ChangeLog

2020-06-02: parce-0.13.0

  • documentation updates and improvements

  • added rule.anyof() and rule.gselect()

  • added the @lexicon consume argument, which puts a switching token in the target context

  • added transform.Items.grouped() and .objects()

  • TreeBuilder.replace_pos() now gets the index as second arg, not the slice

2020-05-18: parce-0.12.0

  • the built-in CSS parser now uses CssTransform to parse a CSS file instead of using the query module

  • added Transformer.connect_treebuilder() to keep a transformed result auto- matically up-to-date.

  • a BackgroundTransformer was added

  • the parent attribute of a tree Node now uses a weak reference

  • the group attribute of a _GroupToken is not a tuple of _GroupTokens anymore, it’s just an integer value indicating the index of the token in the group. This is done to annihilate circular references.

2020-05-13: parce-0.11.0

  • fix NameError: name ‘Escape’ is not defined in parce/css.py

  • in the bundled languages __all__ is defined and from import * is not used anymore

  • documentation improvements

2020-05-13: parce-0.10.0

  • dynamic rule item infrastructure completely rewritten, rule items are simpler, more powerful and fine-grained

  • some modules have been renamed: action → StandardAction is now in standardaction, ActionItem in ruleitem stdactions → action

  • the rule item helpers are not in the parce namepace, but in parce.rule

  • the standard actions are not in the parce namespace, but in parce.action

  • parce.document.Document now inherits from Observable and emits events

  • fixed: AttributeError: ‘str’ object has no attribute ‘IfArg’

2020-05-04: parce-0.9.0

  • initial version of a transform module, that can transform a parce tree to any structure you want using a Transform class, potentionally using caching on contexts

  • added util.Observable, and use it in TreeBuilder to emit events

  • added unicharclass module

  • added using(), like in Pygments, it lexes a match with another lexicon

  • added JavaScript parser

  • added Python console session parser (with prompts)

  • added basic GNU Texinfo parser

  • added groff/troff parser, even includes LilyPond (as per the groff manual!)

  • fixed parsing resume when first part of a match was skipped or not used (e.g. r’( )(“)’, bygroup(skip, String) or r’ (“)’, bygroup(String))

2020-04-25: parce-0.8.5

  • restructured standard actions, easier to combine actions

  • improved default styles, added a template for new CSS styles

  • added oldfashioned terminal CSS style (see parce/themes)

  • parce is now fully recursion proof, there is no limit on the depth of a tree

  • added toml parser

  • added tex/latex parser

  • added HTML parser, building on the XML parser and supporting CSS

  • support score inside markup in LilyPond

  • added the registry module, and the main find() function

  • TreeBuilder.peek(start, tree) now also gets start position

  • default_action can now be a dynamic item (TextItem)

  • added the main maparg() helper

2020-04-07: parce-0.8.0

  • added documentation with examples for bundled languages

  • added ini file parser

  • added mapmember and mapgroupmember rule items

  • tree builder: simpler API, all types now simply use rebuild()

  • tree builder: while building new tree, keep old tree intact

  • tree builder: now it is possible to get fine-grained updates

  • added treebuilder.peek() functionality to get a quick first part of a build

2020-03-14: parce-0.7.0

  • bytext() and bymatch() are now generic “replacables”, they can be used to specify an alternative action, target or both in one go. tomatch() was not needed anymore and is gone.

  • much more replacables, all replacable items now inherit from DynamicItem, (except for Pattern)

  • make it possible to create derived lexicons, e.g. to parse here documents

  • improved LilyPond and Scheme parser

  • added JSON parser

  • lexer resurrected, now generates an event stream, which is used by the tree builder

  • documentation improvements, more examples in doc strings

2020-02-16: parce-0.6.0

  • Large improvements in theme module, MetaTheme working well

  • MetaTheme can render embedded themes with their own window style

  • Added formatter module to format/highlight/colorize text using a Theme

  • More queries in query module, and a query evaluates to False when no results

  • Smart Context.context_slices method that yields slices of nodes per-context for every range. When processing the nodes from each slice we know they originated in the same lexicon and language.

  • Documentation improvements, better cross-linking

2020-02-07: parce-0.5.0

  • Added CSS module to parse and use stylesheets, using CSS lang def

2020-01-22: parce-0.3.0

2020-01-21: livelex-0.3.0

  • add query module

  • fixed util.merge_adjacent_tokens()

  • optimize: when there is only one rule in a lexicon and the pattern does not use regexp classes or qualifiers, and there are no dynamic actions or targets that depend on a match object; convert it to a string and use str.find instead of re.search.
