String Inflections for Haskell
This library is a partial port of the
String Inflector
from Ruby on Rails. It currently implements methods such as parameterize
,
transliterate
, camelize
, underscore
and dasherize
. Please see the
haddock documentation for a complete list of the functions implemented by this
library.
Unlike the ActiveSupport (Rails) and Ember implementations of inflections, this
library uses a parser to verify the input to functions like camelize
. This is
done to ensure that the output strings adhere to the syntax that they are
supposed to generate. You can read more about the philosophy behind this library
in the
Haddock documentation.
Usage
The following examples demonstrate usage of the parameterize
, transliterate
and camelize
functions:
λ: parameterize "Hola. ¿Cómo estás?"
"hola-como-estas"
λ: transliterate "Hola. ¿Cómo estás?"
"Hola. ?Como estas?"
λ: import Control.Monad (liftM)
λ: liftM camelize $ parseSnakeCase "hey_there"
"HeyThere"
Customization
Part of parameterizing strings is approximating all characters in the input
encoding to ASCII characters. This library copies the character approximation
table from the Ruby i18n library. This data structure is provided as
defaultCharacterTransliterations
. You can provide your own transliteration map
by passing a Map structure (from Data.Map) to the parameterizeCustom
function.
If you want to specify a custom default replacement or approximation table for
the transliterate
function, you should instead call the transliterateCustom
function which accepts a String for replacements and a Map for substitution.
TODO
I’d like this library to implement other functions found in the Rails inflections library. If you need one of those functions, please submit a pull request!

Changes
Inflections 0.3.0.0
-
A more type-safe API forbidding creation of invalid words.
-
Made the API use
Text
instead ofString
(which significally improved speed). -
Switched to Megaparsec 5 for parsing.
-
Renamed
defaultMap
todefaultTransliterations
. -
Words now can contain digits (recognized by all parsers).
-
parseSnakeCase
now is not confused when a word happens to have prefix coinciding with an acronym. This is harder to fix forparseCamelCase
because acronym may contain capital letters, so old behavior is preserved forparseCamelCase
for now. -
parseCamelCase
andparseSnakeCase
take any instance ofFoldable
as a collection of acronyms, not just lists. -
Added the
CHANGELOG.md
file. -
Switched test suite to Hspec.
-
The
toUnderscore
,toDashed
, andtoCamelCased
are not partial anymore. They return parse error inLeft
just like parsing functions, but this result can be lifted into any instance ofMonadThrow
withbetterThrow
helper. -
Improved documentation.
