| parsec-string | string | parse a string and consume input for partial matches | | parsec-str | *N/A* | parse a string but consume input only when successful | | parsec-none-of | noneOf | parse any character other than the supplied ones | | parsec-one-of | oneOf | parse one of the characters | | parsec-re | *N/A* | parse using a regular expression | | parsec-eol-or-eof | *N/A* | parse EOL or EOL | | parsec-eof, parsec-eob | eof | parse end of file | | parsec-eol | eol | parse newline or CRLF | | parsec-newline | newline | parse '\n' | | parsec-satisfy | satisfy | parse a character satisfying a predicate | | parsec-any-ch | an圜har | parse an arbitrary character | Byĭefault, their return value is a *string*. These parsing functions are used as the basic building block for a parser. Check the docstring of the function/combinator to see the The *Usage* column for each function/combinator in the following tables is These functions and macros and try them to see the results! They are really If youĭon't have any experience with parser combinators, look at the docstrings of We compare the functions and macros defined in this library with their HaskellĬounterparts, assuming you're already familiar with Haskell's Parsec. port existing Haskell program using Parsec to its equivalent Emacs Lisp use these parser combinators to write parsers easily from scratch in Emacs That it can display an error message showing how the parser fails. =parsec.el= also comes with a simple error handling mechanism so Most of the parser combinators have the same behavior as their HaskellĬounterparts. Of course more combinators can be added if necessary! Most of the parser combinators in =, which should beĮnough in most use cases. So I decided to make a new library on top of it.

It can't show error messages when parsing fails Some of its functions (combinators) have different behaviors than their It only contains a very limited set of combinators The original ] is awesome,īut I found following problems when I tried to use it:
