All notable changes to this project will be documented in this file.
The format is based on Keep a Changelog and this project adheres to Semantic Versioning.
- Optional-line flag behavior now fixed and ~thoroughly tested. Required a change to the accepted behavior, such that an optional pattern matches (1) the line specified, (2) a blank line, or (3) no line.
- The semantics of the 'decimal' and 'float' number tokens have been swapped. 'Decimal' tokens will only match non-scientific-notation decimal values, while 'float' values match either 'decimal' or 'scinot' formatted values.
- "Misc" token type, '&', matching arbitrary non-whitespace content
- Optional whitespace can now be specified after number, literal, and misc tokens, in addition to 'required whitespace after' and 'no whitespace after'
- New helper function
column_stack_2d- Needs performance improvements for large arrays
- New 'optional line' token type
- Works irregularly, perhaps due to quirks in managing optional groups/capture groups within the Python regex engine?
- New property flags on
Tokento indicate the new features added ('misc' token type, optional-whitespace-after, etc.)
- Switched certain lists within the
Parser.capture_structreturn dict structure to a type that automatically passes through a dict key to the single element of those lists, if they are length-one. This simplifies the syntax of a number of use cases by eliminating explicit[0]indexing. Parserinstances now syntax-check theirhead/body/tailpatterns at instantiation, instead of at the first capture attempt.
- Three token types implemented to date: numeric, string-literal, "any"
- Parsing of multiple levels of recursive nested data; tested only to two leves of nesting to date.
- Each nested level of structure can have head/body/tail
- Captured tokens can be easily retrieved from head/tail at the top level parser; no good head or tail capture yet from within nested structures
