HEAD

0.6.1

• Support GHC 8.8.

0.6.0

Breaking Changes

• anySelector now captures text nodes. This causes different results when used with a plural scraper (e.g. chroots). Usage with a singular scraper (e.g. chroot) should be unaffected.
• The dependency on curl has been replaced with http-client and http-client-tls. This has the following observable changes.
  • scrapeURLWithOpts is removed.
  • The Config type used with scrapeURLWithConfig no longer contains a list of curl options. Instead it now takes a Maybe Manager from http-client.
  • The Decoder function type now takes in a Response type from http-client.
  • scrapeURL will now throw an exception if there is a problem connecting to a URL.

Other Changes

• Remove Ord constraint from public APIs.
• Add atDepth operator which allows for selecting nodes at a specified depth in relation to another node (#21).
• Fix issue selecting malformed HTML where "a" // "c" would not match <a><b><c></c></a></b>.
• Add textSelector for selecting text nodes.
• Add SerialScraper type and associated primitives (#48).

0.5.1

• Fix bug (#59, #54) in DFS traversal order.

0.5.0

• Split scalpel into two packages: scalpel and scalpel-core. The latter does not provide networking support and does not depend on curl.

0.4.1

• Added notP attribute predicate.

0.4.0

• Add the chroot tricks (#23 and #25) to README.md and added examples.
• Fix backtracking that occurs when using guard and chroot.
• Fix bug where the same tag may appear in the result set multiple times.
• Performance optimizations when using the (//) operator.
• Make Scraper an instance of MonadFail. Practically this means that failed pattern matches in <- expressions within a do block will evaluate to mzero instead of throwing an error and bringing down the entire script.
• Pluralized scrapers will now return the empty list instead mzero when there are no matches.
• Add the position scraper which provides the index of the current sub-tree within the context of a chroots’s do-block.

0.3.1

• Added the innerHTML and innerHTMLs scraper.
• Added the match function which allows for the creation of arbitrary attribute predicates.
• Fixed build breakage with GHC 8.0.1.

0.3.0.1

• Make tag and attribute matching case-insensitive.

0.3.0

• Added benchmarks and many optimizations.
• The select method is removed from the public API.
• Many methods now have a constraint that the string type parametrizing TagSoup’s tag type now must be order-able.
• Added scrapeUrlWithConfig that will hopefully put an end to multiplying scrapeUrlWith* methods.
• The default behaviour of the scrapeUrl* methods is to attempt to infer the character encoding from the Content-Type header.

0.2.1.1

• Cleanup stale instance references in documentation of TagName and AttributeName.

0.2.1

• Made Scraper an instance of MonadPlus.

0.2.0.1

• Fixed examples in documentation and added an examples folder for ready to compile examples. Added travis tests to ensures that examples remain compilable.

0.2.0

• Removed the StringLike parameter from the Selector, Selectable, AttributePredicate, AttributeName, and TagName types. Instead they are now agnostic to the underlying string type, and are only constructable with Strings and the Any type.

0.1.3.1

• Tighten dependencies and drop download-curl all together.

0.1.3

• Add the html and html scraper primitives for extracting raw HTML.

0.1.2

• Make scrapeURL follow redirects by default.
• Expose a new function scrapeURLWithOpts that takes a list of curl options.
• Fix bug (#2) where image tags that do not have a trailing “/” are not selectable.

0.1.1

• Tighten dependencies on download-curl.

0.1.0

• First version!
