Changes

Internal/api/developer-ish changes in the hledger-lib (and hledger) packages. For user-visible changes, see the hledger package changelog.

1.22.1 2021-08-02

  • Allow megaparsec 9.1

  • journalEndDate’s behaviour has been clarified, journalLastDay has been added.

  • transactionCheckBalanced is now exported. (#1596)

1.22 2021-07-03

  • GHC 9.0 is now officially supported, and GHC 8.0, 8.2, 8.4 are not; building hledger now requires GHC 8.6 or greater.

  • Added now-required lower bound on containers. (#1514)

  • Added useColor, colorOption helpers usable in pure code, eg for debug output.

  • Added a Show instance for AmountDisplayOpts and WideBuilder, for debug logging.

Many internal refactorings/improvements/optimisations by Stephen Morgan, including:

  • Don’t infer a txn price with same-sign amounts. (#1551)

  • Clean up valuation functions, and make clear which to use where. (#1560)

  • Replace journalSelectingAmountFromOpts with journalApplyValuationFromOpts. This also has the effect of allowing valuation in more reports, for example the transactionReport.

  • Refactor to eliminate use of printf.

  • Remove unused String, Text utility functions.

  • Replace concat(Top|Bottom)Padded with textConcat(Top|Bottom)Padded.

  • Export Text.Tabular from Text.Tabular.AsciiWide, clean up import lists.

  • When matching an account query against a posting, don’t try to match against the same posting twice, in cases when poriginal is Nothing.

  • Create mixedAmountApplyValuationAfterSumFromOptsWith for doing any valuation needed after summing amounts.

  • Create journalApplyValuationFromOpts. This does costing and valuation on a journal, and is meant to replace most direct calls of costing and valuation. The exception is for reports which require amounts to be summed before valuation is applied, for example a historical balance report with –value=end.

  • Remove unused (amount|mixedAmount|posting|transaction)ApplyCostValuation functions.

  • Remove unnecessary normalisedMixedAmount.

  • Remove showAmounts*B functions, replacing them entirely with showMixedAmount*B functions.

  • Pull “show-costs” option used by the Close command up into ReporOpts.

  • Add more efficient toEncoding for custom ToJSON declarations.

  • Fix ledgerDateSpan, so that it considers both transaction and posting dates. (#772)

  • Move reportPeriodName to Hledger.Reports.ReportOptions, use it for HTML and CSV output for compound balance reports.

  • Simplify the JSON representation of AmountPrecision. It now uses the same JSON representation as Maybe Word8. This means that the JSON serialisation is now broadly compatible with that used before the commit f6fa76bba7530af3be825445a1097ae42498b1cd, differing only in how it handles numbers outside Word8 and that it can now produce null for NaturalPrecision.

  • A number of AccountName and Journal functions which are supposed to produce unique sorted results now use Sets internally to be slightly more efficient. There is also a new function journalCommodities.

  • More efficiently check whether Amounts are or appear to be zero. Comparing two Quantity (either with == or compare) does a lot of normalisation (calling roundMax) which is unnecessary if we’re comparing to zero. Do things more directly to save work. For reg -f examples/10000x10000x10.journal, this results in

    • A 12% reduction in heap allocations, from 70GB to 62GB
    • A 14% reduction in (profiled) time, from 79s to 70s

    Results for bal -f examples/10000x10000x10.journal are of the same order of magnitude.

  • In sorting account names, perform lookups on HashSets and HashMaps, rather than lists. This is probably not an enormous performance sink in real situations, but it takes a huge amount of time and memory in our benchmarks (specifically 10000x10000x10.journal). For bal -f examples/10000x10000x10.journal, this results in

    • A 23% reduction in heap allocation, from 27GiB to 21GiB
    • A 33% reduction in (profiled) time running, from 26.5s to 17.9s
  • Minor refactor, using foldMap instead of asum . map . toList.

  • Do not call showAmount twice for every posting. For print -f examples/10000x10000x10.journal, this results in a 7.7% reduction in heap allocations, from 7.6GB to 7.1GB.

  • Some efficiency improvements in register reports. Use renderRow interface for Register report.

    For reg -f examples/10000x10000x10.journal, this results in:

    • Heap allocations decreasing by 55%, from 68.6GB to 31.2GB
    • Resident memory decreasing by 75%, from 254GB to 65GB
    • Total (profiled) time decreasing by 55%, from 37s to 20s
  • Split showMixedAmountB into showMixedAmountB and showAmountsB, the former being a simple wrapper around the latter. This removes the need for the showNormalised option, as showMixedAmountB will always showNormalised and showAmountsB will never do so.

  • Change internal representation of MixedAmount to use a strict Map instead of a list of Amounts. No longer export Mixed constructor, to keep API clean. (If you really need it, you can import it directly from Hledger.Data.Types). We also ensure the JSON representation of MixedAmount doesn’t change: it is stored as a normalised list of Amounts.

    This commit improves performance. Here are some indicative results:

    hledger reg -f examples/10000x1000x10.journal
    - Maximum residency decreases from 65MB to 60MB (8% decrease)
    - Total memory in use decreases from 178MiB to 157MiB (12% decrease)
    
    hledger reg -f examples/10000x10000x10.journal
    - Maximum residency decreases from 69MB to 60MB (13% decrease)
    - Total memory in use decreases from 198MiB to 153MiB (23% decrease)
    
    hledger bal -f examples/10000x1000x10.journal
    - Total heap usage decreases from 6.4GB to 6.0GB (6% decrease)
    - Total memory in use decreases from 178MiB to 153MiB (14% decrease)
    
    hledger bal -f examples/10000x10000x10.journal
    - Total heap usage decreases from 7.3GB to 6.9GB (5% decrease)
    - Total memory in use decreases from 196MiB to 185MiB (5% decrease)
    
    hledger bal -M -f examples/10000x1000x10.journal
    - Total heap usage decreases from 16.8GB to 10.6GB (47% decrease)
    - Total time decreases from 14.3s to 12.0s (16% decrease)
    
    hledger bal -M -f examples/10000x10000x10.journal
    - Total heap usage decreases from 108GB to 48GB (56% decrease)
    - Total time decreases from 62s to 41s (33% decrease)
    

    If you never directly use the constructor Mixed or pattern match against it then you don’t need to make any changes. If you do, then do the following:

    • If you really care about the individual Amounts and never normalise your MixedAmount (for example, just storing Mixed amts and then extracting amts as a pattern match, then use should switch to using [Amount]. This should just involve removing the Mixed constructor.
    • If you ever call mixed, normaliseMixedAmount, or do any sort of amount arithmetic (+), (-), then you should replace the constructor Mixed with the function mixed. To extract the list of Amounts, use the function amounts.
    • Any remaining calls to normaliseMixedAmount can be removed, as that is now the identity function.
  • Create a new API for MixedAmount arithmetic. This should supplant the old interface, which relied on the Num typeclass. MixedAmount did not have a very good Num instance. The only functions which were defined were fromInteger, (+), and negate. Furthermore, it was not law-abiding, as 0 + a /= a in general. Replacements for used functions are:

    0 -> nullmixedamt / mempty
    (+) -> maPlus / (<>)
    (-) -> maMinus
    negate -> maNegate
    sum -> maSum
    sumStrict -> maSum
    

    Also creates some new constructors for MixedAmount:

    mixedAmount :: Amount -> MixedAmount
    maAddAmount :: MixedAmount -> Amount -> MixedAmount
    maAddAmounts :: MixedAmount -> [Amount] -> MixedAmount
    

    Add Semigroup and Monoid instances for MixedAmount. Ideally we would remove the Num instance entirely.

    The only change needed have nullmixedamt/mempty substitute for 0 without problems was to not squash prices in mixedAmount(Looks|Is)Zero. This is correct behaviour in any case.

1.21 2021-03-10

  • Building Hledger.Data.Journal no longer fails if the monad-extras package is installed.

  • Many parts of the hledger-lib and hledger APIs have become more Text-ified, expecting or returning Text instead of String, reducing hledger’s time and resident memory requirements by roughly 10%. Some functions now use WideBuilder (a text “builder” which keeps track of width), to concatenate text more efficiently. There are some helpers for converting to and from WideBuilder (wbUnpack, wbToText..) showAmountB/showMixedAmountB are new amount-displaying functions taking an AmountDisplayOpts. These will probably replace the old show(Mixed)Amount* functions. (#1427, Stephen Morgan)

  • AtThen valuation is now implemented for all report types. amountApplyValuation now takes the posting date as an argument. (transaction/posting)ApplyValuation’s valuation type and transaction/posting arguments have been reordered like amountApplyValuation’s. (Stephen Morgan)

  • Amount, AmountPrice, AmountStyle, DigitGroupStyle fields are now strict. (Stephen Morgan)

  • Amount prices are now stored with their sign, so negative prices can be represented. (They seem to have always worked, but now the internal representation is more accurate.) (Stephen Morgan)

  • normaliseMixedAmount now combines Amounts with TotalPrices in the same commodity. (Stephen Morgan)

  • normaliseMixedAmount now uses a strict Map for combining amounts internally, closing a big space leak. (Stephen Morgan)

  • (multiply|divide)(Mixed)?Amount now also multiply or divide the TotalPrice if it is present, and the old (multiply|divide)(Mixed)?AmountAndPrice functions are removed. (Stephen Morgan)

  • (amount|mixedAmount)(Looks|Is)Zero functions now check whether both the quantity and the cost are zero. This is usually what you want, but if you do only want to check whether the quantity is zero, you can run mixedAmountStripPrices (or similar) before this. (Stephen Morgan)

  • commodityStylesFromAmounts now consumes the list immediately, reducing the maximum heap size per thread from ~850K to ~430K in a real-world register report. (Stephen Morgan)

  • *ApplyValuation functions take two less arguments, and *ApplyCostValuation functions have been added, performing both costing and valuation. (Stephen Morgan)

  • traceAtWith now has a level argument and works properly.

  • API changes include:

    Hledger.Data.Amount:
     setAmountPrecision -> amountSetPrecision
     setFullPrecision -> amountSetFullPrecision
     setMixedAmountPrecision -> mixedAmountSetPrecision
     showMixed -> showMixedAmountB
     showMixedLines -> showMixedAmountLinesB
    -mixedAmountSetFullPrecision
    
    Hledger.Data.Journal:
     mapJournalTransactions -> journalMapTransactions
     mapJournalPostings -> journalMapPostings
    -mapTransactionPostings
    +journalPayeesUsed
    +journalPayeesDeclaredOrUsed
    
    Hledger.Data.Transaction:
    +transactionFile
    +transactionMapPostings
    
    Hledger.Data.Valuation:
    -valuationTypeIsCost
    -valuationTypeIsDefaultValue
    -ValuationType's AtDefault constructor
    
    Hledger.Query:
    +matchesDescription
    +matchesPayeeWIP
    
    Hledger.Utils.Text:
    +textConcatBottomPadded
    +wbToText
    +wbUnpack
    
    Text.Tabular.AsciiWide:
     alignCell -> textCell
    

1.20.4 2021-01-29

  • See hledger.

1.20.3 2021-01-14

  • See hledger.

1.20.2 2020-12-28

  • Fix the info manuals’ node structure.

  • Drop unused parsec dependency.

1.20.1 2020-12-15

  • renamed: updateReportSpecFromOpts -> updateReportSpec[With]

1.20 2020-12-05

  • added: journalApplyAliases, transactionApplyAliases, postingApplyAliases

  • a new more robust price lookup implementation, fgl library dropped (#1402)

  • Reverted a stripAnsi change in 1.19.1 that caused a 3x slowdown of amount rendering in terminal reports. (#1350)

  • Amount and table rendering has been improved, so that stripAnsi is no longer needed. This speeds up amount rendering in the terminal, speeding up some reports by 10% or more since 1.19. (Stephen Morgan)

  • global commodity display styles can now be set in InputOpts or Journal, overriding all others (declared or inferred). This is used by the import command and probably command-line options in future.

  • Journal keeps a new piece of parsing state, a decimal mark character, which can optionally be set to force the number format expected by all amount parsers.

  • Remove Empty Query constructor, which does nothing and has done so for a very long time. (Stephen Morgan)

  • In ReportOpts, store query terms term-by-term in a list in querystring_. (Stephen Morgan) This helps deal with tricky quoting issues, as we no longer have to make sure everything is quoted properly before merging it into a string.

  • Implement concat(Top|Bottom)Padded in terms of renderRow, allowing them to be width aware. (Stephen Morgan)

  • Expand Tabular.AsciiWide to allow multiline, custom-width, vertically/horizontally-aligned cells, and optional table borders. (Stephen Morgan)

  • Introduce showMixed*Unnormalised, eliminate most direct calls of strWidth. (Stephen Morgan)

  • showMixedAmountElided now makes better use of space, showing as many Amounts possible as long as they and the elision string fit within 32 characters. (Stephen Morgan)

  • Add Functor instance for CompoundPeriodicReport. (Stephen Morgan)

  • Generalise CBCSubreportSpec to allow more subreport control. (Stephen Morgan)

  • Export some MultiBalanceReport helper functions. (Stephen Morgan)

  • Make Default instances clearer, remove Default instance for Bool. (Stephen Morgan)

  • Many ReportOpts-related changes, such as the addition of ReportSpec, aimed at preventing runtime errors (from parsing: regexps, dates, format strings; from not having today’s date set; etc.) ReportSpec holds a ReportOpts, the day of the report, and the Query generated from these.

  • StringFormat now takes an optional overline width, which is currently only used by defaultBalanceLineFormat. (Stephen Morgan)

  • quoteIfNeeded should not escape the backslashes in unicode code points. (Stephen Morgan)

  • Export OrdPlus and constructors. (Stephen Morgan)

  • Debug output now uses pretty-simple instead pretty-show. This hopefully gives overall nicer debug output (eg in colour), including for values which don’t have Read-able Show output. This means that we can start removing custom Show instances that were a workaround for pretty-show. Eg account names in debug output no longer show their colons as underscores.

    Here’s some old pretty-show output:

    CsvRules { rdirectives = [ ( “skip” , “1” ) ] , rcsvfieldindexes = [ ( “date” , 1 ) , ( “amount” , 2 ) ] , rassignments = [ ( “amount” , “%2” ) , ( “date” , “%1” ) ] , rconditionalblocks = [] }

    And the new pretty-simple output:

    CsvRules { rdirectives= [ ( “skip”, “1” ) ] , rcsvfieldindexes= [ ( “date”, 1 ), ( “amount”, 2 ) ] , rassignments= [ ( “amount”, “%2” ), ( “date”, “%1” ) ] , rconditionalblocks= [] }

    We require pretty-simple 4.0.0.0 to get this compact output. It’s a little less compact than pretty-show, but not too bad. Non-compact pretty-simple output would be:

    CsvRules { rdirectives= [ ( “skip” , “1B” ) ] , rcsvfieldindexes= [ ( “date” , 1 ) , ( “amount” , 2 ) ] , rassignments= [ ( “amount” , “%2” ) , ( “date” , “%1” ) ] , rconditionalblocks=[] }

1.19.1 2020-09-07

  • Allow megaparsec 9

  • stripAnsi: correctly strip ansi sequences with no numbers/semicolons. (Stephen Morgan)

  • Added case-insensitive accountNameToAccountRegexCI, accountNameToAccountOnlyRegexCI, made the default account type queries case insensitive again. (#1341)

1.19 2020-09-01

  • Added a missing lower bound for aeson, making cabal installs more reliable. (#1268)

  • The Regex type alias has been replaced by the Regexp ADT, which contains both the compiled regular expression (so is guaranteed to be usable at runtime) and the original string (so can be serialised, printed, compared, etc.) A Regexp also knows whether is it case sensitive or case insensitive. The Hledger.Utils.Regex API has changed. (#1312, #1330).

  • Typeable and Data instances are no longer derived for hledger’s data types; they were redundant/no longer needed.

  • NFData instances are no longer derived for hledger’s data types. This speeds up a full build by roughly 7%. But it means we can’t deep-evaluate hledger values, or time hledger code with Criterion. https://github.com/simonmichael/hledger/pull/1330#issuecomment-684075129 has some ideas on this.

  • Query no longer has a custom Show instance

  • Hledger.Utils.String: quoteIfNeeded now actually escapes quotes in strings. escapeQuotes was dropped. (Stephen Morgan)

  • Hledger.Utils.Tree: dropped some old utilities

  • Some fromIntegral calls have been replaced with safer code, removing some potential for integer wrapping bugs (#1325, #1326)

  • Parsing numbers with more than 255 decimal places now gives an error instead of silently misparsing (#1326)

  • Digit groups are now limited to at most 255 digits each. (#1326)

  • Exponents are parsed as Integer rather than Int. This means exponents greater than 9223372036854775807 or less than -9223372036854775808 are now parsed correctly, in theory. (In practice, very large exponents will cause hledger to eat all your memory, so avoid them for now.) (#1326)

  • AmountStyle’s asprecision is now a sum type with Word8, instead of an Int with magic values.

  • DigitGroupStyle uses Word8 instead of Int.

  • Partial helper function parsedate has been dropped, use fromGregorian instead.

  • Partial helper function mkdatespan has been dropped.

  • Helper function transaction now takes a Day instead of a date string. (Stephen Morgan)

  • Old CPP directives made redundant by version bounds have been removed. (Stephen Morgan)

  • Smart dates are now represented by the SmartDate type, and are always well formed. (Stephen Morgan)

  • accountTransactionsReport (used for hledger aregister and hledger-ui/hledger-web registers) now filters transactions more thoroughly, so eg transactions dated outside the report period will not be shown. Previously the transaction would be shown if it had any posting dated inside the report period. Possibly some other filter criteria now get applied that didn’t before. I think on balance this will give slightly preferable results.

  • The old BalanceReport code has been dropped at last, replaced by MultiBalanceReport so that all balance reports now use the same code. (Stephen Morgan, #1256).

    • The large multiBalanceReport function has been split up and refactored extensively.
    • Tabular data formerly represented as [[MixedAmount]] is now HashMap AccountName (Map DateSpan Account). Reports with many columns are now faster.
    • Calculating starting balances no longer calls the whole balanceReport, just the first few functions.
    • displayedAccounts is completely rewritten. Perhaps one subtle thing to note is that in tree mode it no longer excludes nodes with zero inclusive balance unless they also have zero exclusive balance.
    • Simon’s note: “I’ll mark the passing of the old multiBalanceReport, into which I poured many an hour :). It is in a way the heart (brain ?) of hledger - the key feature of ledgerlikes (balance report) and a key improvement introduced by hledger (tabular multiperiod balance reports) … Thanks @Xitian9, great work.”

1.18.1 2020-06-21

  • fix some doc typos (Martin Michlmayr)

1.18 2020-06-07

  • added: getHledgerCliOpts’, takes an explicit argument list

  • added: toJsonText

  • changed: isNegativeMixedAmount now gives an answer for multi-commodity amounts which are all negative

  • changed: multiBalanceReport now gets the query from ReportOpts (Dmitry Astapov)

  • renamed: isZeroAmount -> amountLooksZero isReallyZeroAmount -> amountIsZero isZeroMixedAmount -> mixedAmountLooksZero isReallyZeroMixedAmount -> mixedAmountIsZero isReallyZeroMixedAmountCost dropped

  • renamed: finaliseJournal -> journalFinalise

  • renamed: fixedlotpricep -> lotpricep, now also parses non-fixed lot prices

  • dropped: transactionPostingBalances

  • dropped: outputflags no longer exported by Hledger.Cli.CliOptions

  • fixed: documentation for journalExpenseAccountQuery (Pavan Rikhi)

1.17.1 2020-03-19

  • require newer Decimal, math-functions libs to ensure consistent rounding behaviour, even when built with old GHCs/snapshots. hledger uses banker’s rounding (rounds to nearest even number, eg 0.5 displayed with zero decimal places is “0”).

  • added: debug helpers traceAt, traceAtWith

  • Journal is now a Semigroup, not a Monoid (since <> is right-biased). (Stephen Morgan)

1.17.0.1 2020-03-01

  • fix org heading comments and doctest setup comment that were breaking haddock (and in some cases, installation)

1.17 2020-03-01

  • Reader-finding utilities have moved from Hledger.Read to Hledger.Read.JournalReader so the include directive can use them.

  • Reader changes:

    • rExperimental flag removed
    • old rParser renamed to rReadFn
    • new rParser field provides the actual parser. This seems to require making Reader a higher-kinded type, unfortunately.
  • Hledger.Tabular.AsciiWide now renders smoother outer borders in pretty (unicode) mode. Also, a fix for table edges always using single-width intersections and support for double horizontal lines with single vertical lines. (Eric Mertens)

  • Hledger.Utils.Parse: restofline can go to eof also

  • Hledger.Read cleanup

  • Hledger.Read.CsvReader cleanup Exports added: CsvRecord, CsvValue, csvFileFor. Exports removed: expandIncludes, parseAndValidateCsvRules, transactionFromCsvRecord

  • more cleanup of amount canonicalisation helpers (#1187) Stop exporting journalAmounts, overJournalAmounts, traverseJournalAmounts. Rename journalAmounts helper to journalStyleInfluencingAmounts.

  • export mapMixedAmount

  • Don’t store leaf name in PeriodReport. (Stephen Morgan) Calculate at the point of consumption instead.

  • Generalise PeriodicReport to be polymorphic in the account labels. (Stephen Morgan)

  • Use records instead of tuples in PeriodicReport. (Stephen Morgan)

  • Use PeriodicReport in place of MultiBalanceReport. (Stephen Morgan)

  • Calculate MultiReportBalance columns more efficiently. (Stephen Morgan) Only calculate posting date once for each posting, and calculate their columns instead of checking each DateSpan separately.

  • Moved JSON instances from hledger-web to hledger-lib (Hledger.Data.Json), and added ToJSON instances for all (?) remaining data types, up to Ledger.

  • Dropped nullassertion’s “assertion” alias, fixing a warning. Perhaps we’ll stick with the null* naming convention.

1.16.2 2020-01-14

  • add support for megaparsec 8 (#1175)

1.16.1 2019-12-03

  • Drop unnecessary mtl-compat dependency

  • Fix building with GHC 8.0, 8.2

1.16 2019-12-01

  • drop support for GHC 7.10, due to MonadFail hassles in JournalReader.hs

  • add support for GHC 8.8, base-compat 0.11 (#1090)

    We are now using the new fail from the MonadFail class, which we always import qualified as Fail.fail, from base-compat-batteries Control.Monad.Fail.Compat to work with old GHC versions. If old fail is needed (shouldn’t be) it should be imported qualified as Prelude.Fail, using imports such as:

    import Prelude hiding (fail)
    import qualified Prelude (fail)
    import Control.Monad.State.Strict hiding (fail)
    import "base-compat-batteries" Prelude.Compat hiding (fail)
    import qualified "base-compat-batteries" Control.Monad.Fail.Compat as Fail
    
  • hledger and hledger-lib unit tests have been ported to tasty.

  • The doctest suite has been disabled for now since it doesn’t run well with cabal (#1139)

  • accountTransactionsReportItems: rewrite using catMaybes and mapAccumL (Henning Thielemann)
  • optionally save the current date in ReportOpts
  • Hledger.Cli tests now have correct prefix; add Cli.Utils tests
  • MultiBalanceReport now returns zero for row totals when in cumulative or historical mode (#329)

1.14.1 2019-03-20

  • require easytest <0.3 to fix build issue

1.14 2019-03-01

  • added:
    transaction, [v]post*, balassert* constructors, for tests etc.

  • renamed:
    porigin -> poriginal

  • refactored:
    transaction balancing & balance assertion checking (#438)

1.13.1 (2019/02/02)

  • stop depending on here to avoid haskell-src-meta/stackage blockage.

1.13 (2019/02/01)

  • in Journal’s jtxns field, forecasted txns are appended rather than prepended

  • API changes:

    added: +setFullPrecision +setMinimalPrecision +expectParseStateOn +embedFileRelative +hereFileRelative

    changed:

    • amultiplier -> aismultiplier

    • Amount fields reordered for clearer debug output

    • tpreceding_comment_lines -> tprecedingcomment, reordered

    • Hledger.Data.TransactionModifier.transactionModifierToFunction -> modifyTransactions

    • Hledger.Read.Common.applyTransactionModifiers -> Hledger.Data.Journal.journalModifyTransactions

    • HelpTemplate -> CommandDoc

1.12 (2018/12/02)

  • switch to megaparsec 7 (Alex Chen) We now track the stack of include files in Journal ourselves, since megaparsec dropped this feature.

  • add ‘ExceptT’ layer to our parser monad again (Alex Chen) We previously had a parser type, ‘type ErroringJournalParser = ExceptT String …’ for throwing parse errors without allowing further backtracking. This parser type was removed under the assumption that it would be possible to write our parser without this capability. However, after a hairy backtracking bug, we would now prefer to have the option to prevent backtracking.

    • Define a ‘FinalParseError’ type specifically for the ‘ExceptT’ layer
    • Any parse error can be raised as a “final” parse error
    • Tracks the stack of include files for parser errors, anticipating the removal of the tracking of stacks of include files in megaparsec 7
      • Although a stack of include files is also tracked in the ‘StateT Journal’ layer of the parser, it seems easier to guarantee correct error messages in the ‘ExceptT FinalParserError’ layer
      • This does not make the ‘StateT Journal’ stack redundant because the ‘ExceptT FinalParseError’ stack cannot be used to detect cycles of include files
  • more support for location-aware parse errors when re-parsing (Alex Chen)

  • make ‘includedirectivep’ an ‘ErroringJournalParser’ (Alex Chen)

  • drop Ord instance breaking GHC 8.6 build (Peter Simons)

  • flip the arguments of (divide|multiply)[Mixed]Amount

  • showTransaction: fix a case showing multiple missing amounts showTransaction could sometimes hide the last posting’s amount even if one of the other posting amounts was already implicit, producing invalid transaction output.

  • plog, plogAt: add missing newline

  • split up journalFinalise, reorder journal finalisation steps (#893) (Jesse Rosenthal) The journalFinalise function has been split up, allowing more granular control.

  • journalSetTime –> journalSetLastReadTime

  • journalSetFilePath has been removed, use journalAddFile instead

1.11.1 (2018/10/06)

  • add, lib: fix wrong transaction rendering in balance assertion errors and when using the add command

1.11 (2018/9/30)

  • compilation now works when locale is unset (#849)

  • all unit tests have been converted from HUnit+test-framework to easytest

  • doctests now run quicker by default, by skipping reloading between tests. This can be disabled by passing –slow to the doctests test suite executable.

  • doctests test suite executable now supports –verbose, which shows progress output as tests are run if doctest 0.16.0+ is installed (and hopefully is harmless otherwise).

  • doctests now support file pattern arguments, provide more informative output. Limiting to just the file(s) you’re interested can make doctest start much quicker. With one big caveat: you can limit the starting files, but it always imports and tests all other local files those import.

  • a bunch of custom Show instances have been replaced with defaults, for easier troubleshooting. These were sometimes obscuring important details, eg in test failure output. Our new policy is: stick with default derived Show instances as far as possible, but when necessary adjust them to valid haskell syntax so pretty-show can pretty-print them (eg when they contain Day values, cf https://github.com/haskell/time/issues/101). By convention, when fields are shown in less than full detail, and/or in double-quoted pseudo syntax, we show a double period (..) in the output.

  • Amount has a new Show instance. Amount’s show instance hid important details by default, and showing more details required increasing the debug level, which was inconvenient. Now it has a single show instance which shows more information, is fairly compact, and is pretty-printable.

    ghci> usd 1
    OLD:
    Amount {acommodity="$", aquantity=1.00, ..}
    NEW:
    Amount {acommodity = "$", aquantity = 1.00, aprice = NoPrice, astyle = AmountStyle "L False 2 Just '.' Nothing..", amultiplier = False}
    

    MixedAmount’s show instance is unchanged, but showMixedAmountDebug is affected by this change:

    ghci> putStrLn $ showMixedAmountDebug $ Mixed [usd 1]
    OLD:
    Mixed [Amount {acommodity="$", aquantity=1.00, aprice=, astyle=AmountStyle {ascommodityside = L, ascommodityspaced = False, asprecision = 2, asdecimalpoint = Just '.', asdigitgroups = Nothing}}]
    NEW:
    Mixed [Amount {acommodity="$", aquantity=1.00, aprice=, astyle=AmountStyle "L False 2 Just '.' Nothing.."}]
    
  • Same-line & next-line comments of transactions, postings, etc. are now parsed a bit more precisely (followingcommentp). Previously, parsing no comment gave the same result as an empty comment (a single newline); now it gives an empty string.
    Also, and perhaps as a consequence of the above, when there’s no same-line comment but there is a next-line comment, we’ll insert an empty first line, since otherwise next-line comments would get moved up to the same line when rendered.

  • Hledger.Utils.Test exports HasCallStack

  • queryDateSpan, queryDateSpan’ now intersect date AND’ed date spans instead of unioning them, and docs are clearer.

  • pushAccount -> pushDeclaredAccount

  • jaccounts -> jdeclaredaccounts

  • AutoTransaction.hs -> PeriodicTransaction.hs & TransactionModifier.hs

  • Hledger.Utils.Debug helpers have been renamed/cleaned up

1.10 (2018/6/30)

  • build cleanly with all supported GHC versions again (7.10 to 8.4)

  • support/use latest base-compat (#794)

  • support/require megaparsec 6.4+

  • extensive refactoring and cleanup of parsers and related types and utilities

  • readJournalFile(s) cleanup, these now use InputOpts

  • doctests now run a bit faster (#802)

1.9.1 (2018/4/30)

  • new generic PeriodicReport, and some report-related type aliases

  • new BudgetReport

  • make (readJournal|tryReader)s?WithOpts the default api, dropping “WithOpts”

  • automated postings and command line account aliases happen earlier in journal processing (see hledger changelog)

1.9 (2018/3/31)

  • support ghc 8.4, latest deps

  • when the system text encoding is UTF-8, ignore any UTF-8 BOM prefix found when reading files.

  • CompoundBalanceReport amounts are now normally positive. The bs/bse/cf/is commands now show normal income, liability and equity balances as positive. Negative numbers now indicate a contra-balance (eg an overdrawn checking account), a net loss, a negative net worth, etc. This makes these reports more like conventional financial statements, and easier to read and share with others. (experimental)

  • splitSpan now returns no spans for an empty datespan

  • don’t count periodic/modifier txns in Journal debug output

  • lib/ui/web/api: move embedded manual files to extra-source-files

  • Use skipMany/skipSome for parsing spacenonewline (Moritz Kiefer) This avoids allocating the list of space characters only to then discard it.

  • rename, clarify purpose of balanceReportFromMultiBalanceReport

  • fix some hlint warnings

  • add some easytest tests

1.5 (2017/12/31)

  • -V/–value uses today’s market prices by default, not those of last transaction date. #683, #648)

  • csv: allow balance assignment (balance assertion only, no amount) in csv records (Nadrieril)

  • journal: allow space as digit group separator character, #330 (Mykola Orliuk)

  • journal: balance assertion errors now show line of failed assertion posting, #481 (Sam Jeeves)

  • journal: better errors for directives, #402 (Mykola Orliuk)

  • journal: better errors for included files, #660 (Mykola Orliuk)

  • journal: commodity directives in parent files are inherited by included files, #487 (Mykola Orliuk)

  • journal: commodity directives limits precision even after -B, #509 (Mykola Orliuk)

  • journal: decimal point/digit group separator chars are now inferred from an applicable commodity directive or default commodity directive. #399, #487 (Mykola Orliuk)

  • journal: numbers are parsed more strictly (Mykola Orliuk)

  • journal: support Ledger-style automated postings, enabled with –auto flag (Dmitry Astapov)

  • journal: support Ledger-style periodic transactions, enabled with –forecast flag (Dmitry Astapov)

  • period expressions: fix “nth day of {week,month}”, which could generate wrong intervals (Dmitry Astapov)

  • period expressions: month names are now case-insensitive (Dmitry Astapov)

  • period expressions: stricter checking for invalid expressions (Mykola Orliuk)

  • period expressions: support “every 11th Nov” (Dmitry Astapov)

  • period expressions: support “every 2nd Thursday of month” (Dmitry Astapov)

  • period expressions: support “every Tuesday”, short for “every th day of week” (Dmitry Astapov)

  • remove upper bounds on all but hledger* and base (experimental) It’s rare that my deps break their api or that newer versions must be avoided, and very common that they release new versions which I must tediously and promptly test and release hackage revisions for or risk falling out of stackage. Trying it this way for a bit.

1.4 (2017/9/30)

  • add readJournalFile[s]WithOpts, with simpler arguments and support for detecting new transactions since the last read.

  • query: add payee: and note: query terms, improve description/payee/note docs (Jakub Zárybnický, Simon Michael, #598, #608)

  • journal, cli: make trailing whitespace significant in regex account aliases Trailing whitespace in the replacement part of a regular expression account alias is now significant. Eg, converting a parent account to just an account name prefix: –alias ‘/:acct:/=:acct’

  • timedot: allow a quantity of seconds, minutes, days, weeks, months or years to be logged as Ns, Nm, Nd, Nw, Nmo, Ny

  • csv: switch the order of generated postings, so account1 is first. This simplifies things and facilitates future improvements.

  • csv: show the “creating/using rules file” message only with –debug

  • csv: fix multiple includes in one rules file

  • csv: add “newest-first” rule for more robust same-day ordering

  • deps: allow ansi-terminal 0.7

  • deps: add missing parsec lower bound, possibly related to #596, fpco/stackage#2835

  • deps: drop oldtime flag, require time 1.5+

  • deps: remove ghc < 7.6 support, remove obsolete CPP conditionals

  • deps: fix test suite with ghc 8.2

1.3.1 (2017/8/25)

  • Fix a bug with -H showing nothing for empty periods (#583, Nicholas Niro) This patch fixes a bug that happened when using the -H option on a period without any transaction. Previously, the behavior was no output at all even though it should have shown the previous ending balances of past transactions. (This is similar to previously using -H with -E, but with the extra advantage of not showing empty accounts)

  • allow megaparsec 6 (#594)

  • allow megaparsec-6.1 (Hans-Peter Deifel)

  • fix test suite with Cabal 2 (#596)

1.3 (2017/6/30)

journal: The “uncleared” transaction/posting status, and associated UI flags and keys, have been renamed to “unmarked” to remove ambiguity and confusion. This means that we have dropped the --uncleared flag, and our -U flag now matches only unmarked things and not pending ones. See the issue and linked mail list discussion for more background. (#564)

csv: assigning to the “balance” field name creates balance assertions (#537, Dmitry Astapov).

csv: Doubled minus signs are handled more robustly (fixes #524, Nicolas Wavrant, Simon Michael)

Multiple “status:” query terms are now OR’d together. (#564)

deps: allow megaparsec 5.3.

1.2 (2017/3/31)

journal format

A pipe character can optionally be used to delimit payee names in transaction descriptions, for more accurate querying and pivoting by payee. Eg, for a description like payee name | additional notes, the two parts will be accessible as pseudo-fields/tags named payee and note.

Some journal parse errors now show the range of lines involved, not just the first.

ledger format

The experimental ledger: reader based on the WIP ledger4 project has been disabled, reducing build dependencies.

Misc

Fix a bug when tying the knot between postings and their parent transaction, reducing memory usage by about 10% (#483) (Mykola Orliuk)

Fix a few spaceleaks (#413) (Moritz Kiefer)

Add Ledger.Parse.Text to package.yaml, fixing a potential build failure.

Allow megaparsec 5.2 (#503)

Rename optserror -> usageError, consolidate with other error functions

1.1 (2016/12/31)

journal format

  • balance assignments are now supported (#438, #129, #157, #288)

    This feature also brings a slight performance drop (~5%); optimisations welcome.

  • also recognise *.hledger files as hledger journal format

ledger format

  • use ledger-parse from the ledger4 project as an alternate reader for C++ Ledger journals

    The idea is that some day we might get better compatibility with Ledger files this way. Right now this reader is not very useful and will be used only if you explicitly select it with a ledger: prefix. It parses transaction dates, descriptions, accounts and amounts, and ignores everything else. Amount parsing is delegated to hledger’s journal parser, and malformed amounts might be silently ignored.

    This adds at least some of the following as new dependencies for hledger-lib: parsers, parsec, attoparsec, trifecta.

misc

  • update base lower bound to enforce GHC 7.10+

    hledger-lib had a valid install plan with GHC 7.8, but currently requires GHC 7.10 to compile. Now we require base 4.8+ everywhere to ensure the right GHC version at the start.

  • Hledger.Read api cleanups

  • rename dbgIO to dbg0IO, consistent with dbg0, and document a bug in dbg*IO

  • make readJournalFiles [f] equivalent to readJournalFile f (#437)

  • more general parser types enabling reuse outside of IO (#439)

1.0.1 (2016/10/27)

  • allow megaparsec 5.0 or 5.1

1.0 (2016/10/26)

timedot format

  • new “timedot” format for retroactive/approximate time logging.

    Timedot is a plain text format for logging dated, categorised quantities (eg time), supported by hledger. It is convenient for approximate and retroactive time logging, eg when the real-time clock-in/out required with a timeclock file is too precise or too interruptive. It can be formatted like a bar chart, making clear at a glance where time was spent.

timeclock format

  • renamed “timelog” format to “timeclock”, matching the emacs package

  • sessions can no longer span file boundaries (unclocked-out

    sessions will be auto-closed at the end of the file).

  • transaction ids now count up rather than down (#394)

  • timeclock files no longer support default year directives

  • removed old code for appending timeclock transactions to journal transactions.

    A holdover from the days when both were allowed in one file.

csv format

  • fix empty field assignment parsing, rule parse errors after megaparsec port (#407) (Hans-Peter Deifel)

journal format

  • journal files can now include timeclock or timedot files (#320)

    (but not yet CSV files).

  • fixed an issue with ordering of same-date transactions included from other files

  • the “commodity” directive and “format” subdirective are now supported, allowing

    full control of commodity style (#295) The commodity directive’s format subdirective can now be used to override the inferred style for a commodity, eg to increase or decrease the precision. This is at least a good workaround for #295.

  • Ledger-style “apply account”/“end apply account” directives are now used to set a default parent account.

  • the Ledger-style “account” directive is now accepted (and ignored).

  • bracketed posting dates are more robust (#304)

    Bracketed posting dates were fragile; they worked only if you wrote full 10-character dates. Also some semantics were a bit unclear. Now they should be robust, and have been documented more clearly. This is a legacy undocumented Ledger syntax, but it improves compatibility and might be preferable to the more verbose “date:” tags if you write posting dates often (as I do). Internally, bracketed posting dates are no longer considered to be tags. Journal comment, tag, and posting date parsers have been reworked, all with doctests.

  • balance assertion failure messages are clearer

  • with –debug=2, more detail about balance assertions is shown.

misc

  • file parsers have been ported from Parsec to Megaparsec \o/ (#289, #366) (Alexey Shmalko, Moritz Kiefer)

  • most hledger types have been converted from String to Text, reducing memory usage by 30%+ on large files

  • file parsers have been simplified for easier troubleshooting (#275).

    The journal/timeclock/timedot parsers, instead of constructing opaque journal update functions which are later applied to build the journal, now construct the journal directly by modifying the parser state. This is easier to understand and debug. It also rules out the possibility of journal updates being a space leak. (They weren’t, in fact this change increased memory usage slightly, but that has been addressed in other ways). The ParsedJournal type alias has been added to distinguish “being-parsed” journals and “finalised” journals.

  • file format detection is more robust.

    The Journal, Timelog and Timedot readers’ detectors now check each line in the sample data, not just the first one. I think the sample data is only about 30 chars right now, but even so this fixed a format detection issue I was seeing. Also, we now always try parsing stdin as journal format (not just sometimes).

  • all file formats now produce transaction ids, not just journal (#394)

  • git clone of the hledger repo on windows now works (#345)

  • added missing benchmark file (#342)

  • our stack.yaml files are more compatible across stack versions (#300)

  • use newer file-embed to fix ghci working directory dependence (https://github.com/snoyberg/file-embed/issues/18)

  • report more accurate dates in account transaction report when postings have their own dates

    (affects hledger-ui and hledger-web registers). The newly-named “transaction register date” is the date to be displayed for that transaction in a transaction register, for some current account and filter query. It is either the transaction date from the journal (“transaction general date”), or if postings to the current account and matched by the register’s filter query have their own dates, the earliest of those posting dates.

  • simplify account transactions report’s running total.

    The account transactions report used for hledger-ui and -web registers now gives either the “period total” or “historical total”, depending strictly on the –historical flag. It doesn’t try to indicate whether the historical total is the accurate historical balance (which depends on the user’s report query).

  • reloading a file now preserves the effect of options, query arguments etc.

  • reloading a journal should now reload all included files as well.

  • the Hledger.Read.* modules have been reorganised for better reuse.

    Hledger.Read.Utils has been renamed Hledger.Read.Common and holds low-level parsers & utilities; high-level read utilities are now in Hledger.Read.

  • clarify amount display style canonicalisation code and terminology a bit.

    Individual amounts still have styles; from these we derive the standard “commodity styles”. In user docs, we might call these “commodity formats” since they can be controlled by the “format” subdirective in journal files.

  • Journal is now a monoid

  • expandPath now throws a proper IO error

  • more unit tests, start using doctest

0.27 (2015/10/30)

  • The main hledger types now derive NFData, which makes it easier to time things with criterion.

  • Utils has been split up more.

  • Utils.Regex: regular expression compilation has been memoized, and memoizing versions of regexReplace[CI] have been added, since compiling regular expressions every time seems to be quite expensive (#244).

  • Utils.String: strWidth is now aware of multi-line strings (#242).

  • Read: parsers now use a consistent p suffix.

  • New dependencies: deepseq, uglymemo.

  • All the hledger packages’ cabal files are now generated from simpler, less redundant yaml files by hpack, in principle. In practice, manual fixups are still needed until hpack gets better, but it’s still a win.

0.26 (2015/7/12)

  • allow year parser to handle arbitrarily large years
  • Journal’s Show instance reported one too many accounts
  • some cleanup of debug trace helpers
  • tighten up some date and account name parsers (don’t accept leading spaces; hadddocks)
  • drop regexpr dependency

  • fix combineJournalUpdates folding order
  • fix a regexReplaceCI bug
  • fix a splitAtElement bug with adjacent separators
  • mostly replace slow regexpr with regex-tdfa (fixes #189)
  • use the modern Text.Parsec API
  • allow transformers 0.4*
  • regexReplace now supports backreferences
  • Transactions now remember their parse location in the journal file
  • export Regexp types, disambiguate CsvReader’s similarly-named type
  • export failIfInvalidMonth/Day (fixes #216)
  • track the commodity of zero amounts when possible (useful eg for hledger-web’s multi-commodity charts)
  • show posting dates in debug output
  • more debug helpers

0.23.3 (2014/9/12)

  • allow transformers 0.4*

0.23.2 (2014/5/8)

  • postingsReport: also fix date sorting of displayed postings (#184)

0.23.1 (2014/5/7)

  • postingsReport: with disordered journal entries, postings before the report start date could get wrongly included. (#184)

0.23 (2014/5/1)

  • orDatesFrom -> spanDefaultsFrom

0.22.2 (2014/4/16)

  • display years before 1000 with four digits, not three
  • avoid pretty-show to build with GHC < 7.4
  • allow text 1.1, drop data-pprint to build with GHC 7.8.x

0.22.1 (2014/1/6) and older: see http://hledger.org/release-notes or doc/CHANGES.md.
