Full description

Emacs wisi package 3.0.1

The wisi package provides utilities for using generalized
error-correcting LR parsers (in external processes) to do indentation,
fontification, and navigation; and integration with Emacs package.el.
See ada-mode for an example of its use.

It also provides wisitoken-parse_table-mode, for navigating the
diagnostic parse tables output by wisitoken-bnf-generate.

* wisi 3.0.1
30 Jan 2020

** fix packaging bugs

** improve xref integration

* wisi 3.0.0
19 Dec 2019

** parser process protocol version 5

** Add project.el integration. See wisi.info for more information.

** Move autocase functions from ada-mode to wisi.

** Replace most ada-mode function variables with dispatching on wisi-prj.

** New commands `wisi-goto-containing-statement-start', `wisi-indent-containing-statement'.

** Displayed parser errors are sorted in increasing error position.

* wisi 2.2.1
17 Aug 2019

** parser process protocol version 4

** fix packaging bugs

* wisi 2.2.0
13 Aug 2019

** parser process protocol version 3

** Support for the elisp parser and lexer is deleted; only the Ada
   process parser is supported.

** New user variable `wisi-indent-context-lines' specifies the minimum
   number of lines before point to include in a parse for indenting a
   single line. This gives better results when indenting in a nested
   'if then else', for example. The default value is 0; you must
   change it to see an effect.

** Error correction is faster by approximately 30%;
   %mckenzie_enqueue_limit can be raised accordingly.

** %mckenzie_enqueue_limit is now applied to the total of all parsers
    in recovery; previously, it was applied to each parser separately.
    Applying to the total gives a more consistent maximum user wait
    time for recovery, at the cost of not finding solutions when there
    are many parsers involved. You may want to increase
    %mckenzie_enqueue_limit for this as well.

** In the process parser, `wisi-statement-start' now sets 'containing'
   in all contained caches to the start token, if not set already;
   previously it only did this if the token was mentioned in the
   `wisi-statement-start' action. This makes `wisi-containing-action'
   unnecessary.

** `wisi-containing-action' is deleted.

** An argument of `wisi-motion-action' that is a vector may now
   provide only one token ID. That token ID is searched for in the
   containing token region, and the motion token chain starting at the
   first one found is included in the current right hand side motion
   token chain.

** The process parser supports a new parse command `wisi-refactor',
   which returns a new message "Edit". It is intended for performing
   syntax-guided refactoring of code statements.

* wisi 2.1.1
11 Jul 2019

** parser process protocol version 3

** User variable wisi-mckenzie-cost-limit is deleted; set
   wisi-mckenzie-enqueue-limit instead, it gives better results.

** `wisi-show-parse-errors' now shows errors in a dedicated window, so
   it will not be resized or reused.

** New grammar action `wisi-name-action'; sets a name that will be
   fontified. This replaces the previous 'name' navigate class.

** Support 'nil' as an indent argument; useful for the first token,
   whose indent is typically unknown. Indent functions that do not
   accumulate now only check for "nil", not "zero or nil".

** New file wisi-xref.el provides a completion table built from tokens
   marked by the new grammar action `wisi-name-action'.

** The process parser checks the parser process protocol version, to
   ensure the elisp code matches the process code.

** The process parser supports passing data to a language-specific
   elisp function, via the `language-action-table' field of the
   `wisi-process--parser' struct.

** New user option `wisi-parse-max-parallel' to set the number of
   parallel parsers used; Java needs more than Ada.

* wisi 2.1.0
21 Mar 2019

** parser process protocol version 2

** Add support for partial parsing; useful in very large files. Files
   larger than wisi-partial-parse-threshold (default 100_001) will be
   parsed partially.

** Miscellaneous speed-ups in the Ada code; 'pragma Inline', better use of Ada tasks.

** Better error correction in the Ada process parser; insert minimimal
  tokens to complete a statement/declaration before or after the error
  point.

* wisi 2.0.1
8 Dec 2018

** parser process protocol version 1

** Assign copyright in Ada files to FSF

** Update user guide, include it in elpa package

* wisi 2.0.0
17 Nov 2018

** Change indentation engine to compute indent directly in parser actions.

** Add error correcting external process parser.

** Factor out wisi-elisp-lexer.el from wisi.el, and
   ada-wisi-elisp-parse.el from ada-wisi.el. Move elisp grammar
   actions from wisi.el to wisi-elisp-parse.el; they are not used with
   the process parser.

** Add support for error corrections in parser; 'wisi-repair-error'
   can apply the corrections to the buffer text.

** Display marks in fringe at location of errors detected by
   background parser.

** include sources for wisitoken parser runtime, parser generator.

* wisi 1.1.6
3 Oct 2017

** wisi-forward-find-cache-token - new function.

** New minor-mode parse_table-mode helps navigating parse table
   listings output by 'wisi-generate -v 1'; useful when debugging
   grammars.

* wisi 1.1.5
9 Jul 2017

** wisi-indent-fallback allows setting the indent engine to use when
   the wisi engine fails.

** wisi-comment-indent now uses comment-column for comments following
   code on the same line.

** wisi-forward-statement-keyword tolerates end of buffer, and uses
   either cache-next or cache-end.

** forward-sexp-function is set to wisi-forward-sexp, which handles
   parens, strings, and statements.

* wisi 1.1.4
31 Oct 2016

** wisi-validate-cache takes optional error-on-fail arg.

* wisi 1.1.3

** improve use of quotes in doc strings.

* wisi 1.1.2

   external parser, catches more errors.

* wisi 1.0.6
