* genvim: take advantage of @(if) in @(output)Kaz Kylheku2020-07-081-10/+2
| | | | | * genvim.txr (generate): Use a single, undivided @(output) block instead of multiple blocks with :continue.
* genvim: work around Vim "contains" bug.Kaz Kylheku2020-04-181-1/+3
| | | | | | | * genvim.txr (tl-sym): Recognize the contains symbol and render it as the string "contain[s]". Vim thinks that contains is reserved a keyword, anywhere in the syn keyword line, and throws an error.
* genvim: colon isn't keyword constituent any more.Kaz Kylheku2020-03-071-1/+1
| | | | | | | | | | | * genvim (iskeyword): Remove the : character from being a symbol constituent. This doesn't work well with tags, which are oblivious to packages. We would not only have to make tags.tl deal with packages, but in the tags file we would have to duplicate every entry with and without the package prefix. It doesn't make a lot of sense. Plus, packages themselves are tags, and if we put the cursor on the package part of a qualified symbol, we can jump to the package.
* genvim: treatment of comments.Kaz Kylheku2019-04-041-0/+2
| | | | | * genvim.txr (comments): new variable. Generate "set comments" command for TXR and TXR Lisp.
* vim: colorize hash bang for Lisp.Kaz Kylheku2018-11-061-1/+2
| | | | | | * genvim.txr: generate the txr_hashbang match in both txr.vim and tl.vim, not only txr.vim. Use Vim's \% regex operator to match only in the first line of a file.
* genvim: include .tlo files in vimrc example.Kaz Kylheku2018-10-281-2/+2
| | | | | * genvim.txr: In the Vim syntax file comment's example .vimrc lines, include .tlo files, which are just TXR Lisp syntax.
* genvim: % is constituent of identifiers.Kaz Kylheku2017-10-301-1/+1
| | | | * genvim.txr (iskeyword): add % character.
* genvim: ^ is constituent of identifiers.Kaz Kylheku2017-08-011-1/+1
| | | | | * genvim.txr (iskeyword): add ^ character. Now r^ and others are colorized properly.
* genvim: flag trailing junk in #x #o #b literals.Kaz Kylheku2017-07-291-9/+14
| | | | | | | | | | | * genvim.txr (txr_pnum): New match; matches a superset of the #x, #o and #b literals with the inclusion of trailing alphanumeric junk. Highlighted as Error. (txr_xnum, txr_onum, txr_bnum): New match categories, formed by renaming the previous #x, #o and #b matches. These are contained in txr_pnum, highlighted as Number. (txr_bracevar, txr_directive, txr_list, txr_bracket, txr_mlist, txr_mbracket): Include txr_pnum.
* genvim: flag invalid # syntax.Kaz Kylheku2017-07-281-0/+2
| | | | | | | * genvim.txr (txr_error): New match in this category for # followed by something other than H, S or R. Some characters other than these are valid after #, but are covered by explicit matches that occur later.
* genvim: fix buggy tl_ident containing #.Kaz Kylheku2017-07-281-1/+1
| | | | | | | * genvim.txr (tl_ident): Fix the incorrect match which allows things beginning with # to be categorized as identifier tokens. The new match reflects the true original intent: the match must not begin with #, but may contain #.
* genvim: highlight buffer literals.Kaz Kylheku2017-07-281-4/+11
| | | | | | | * genvim.txr (txr_buf_error, txr_buf_interior): New matches. (txr_list, txr_bracket, txr_mlist, txr_mbracket): Now also contain txr_buf. (txr_buf): New region, in the new txr_string matchgroup.
* genvim: bugfix for #x, #o and #b integer tokensKaz Kylheku2017-07-271-3/+3
| | | | | | | * genvim.txr (txr_num): Move the syn match definitions for hex, octal and binary integer tokens after tl_ident, which is a more general match that matches them also, and causes them to be colorized as symbols rather than numbers.
* genvim: include ffi type symbols.Kaz Kylheku2017-06-301-2/+4
| | | | | | * genvim.txr: do syntax coloring for symbols that are defined as FFI types or are FFI type operators. Also, include type operators in the Vim lispwords list.
* genvim: remove useless code.Kaz Kylheku2017-06-301-4/+0
| | | | | | | | | * genvim.txr: remove code which probes a few symbols with boundp. The point of this is to stimulate some autoloading, but it is based on a misunderstanding. The symbols in the lisplib.c autoload module are all interned. When the usr package is walked, they all get checked with boundp, and all all library autoloads are triggered.
* vim: colorize #n= and #n#.Kaz Kylheku2016-11-111-6/+8
| | | | | | | | | * genvim.txr (txr_circ): New match. Link to Special highlight group. (txr_bracevar, txr_directive, txr_list, txr_mlist, txr_mbracket): Introduce txr_circ into these regions. * txr.vim, tl.vim: Regenerated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * parser.c (parser_circ_ref): Don't generate the circular reference if circular suppression is in effect. * parser.h (struct parser): New member, circ_suppress. We use this for suppressing the generation of circular #n# references in erased objects. * parser.l (grammar): Scan #; producing HASH_SEMI token. * parser.y (HASH_SEMI): New token. (hash_semis_n_expr, hash_semis_i_expr, ignored_i_exprs, ignored_n_exprs): New nonterminals, needed for supporting the use of #; in front of top-level forms. (spec): Use hash_semis_n_expr and hash_semis_i_expr instead of n_expr and i_expr. (r_expr): Support object erasure within nested syntax. (yybadtoken): Handle H_SEMI token. (parse): Initialize new circ_suppress member of parser struct to zero. * txr.1: Documented. * genvim.txr (txr_ign_par, txr_ign_bkt, txr_ign_par_interior, txr_ign_bkt_interior): New regions for colorizing erased objects (partial support). (txr_list, txr_bracket, txr_mlist, txr_mbrackets): Include erased objects by including regions txr_ign_par and txr_ign_bkt. * txr.vim, tl.vim: Regenerated.
* vim syntax: support #H properly, plus #R, #S.Kaz Kylheku2016-11-071-1/+1
| | | | | | * genvim.txr (txr_list): Rewrite start delimiter regex. * txr.vim, tl.vim: Regenerated.
* Get rid of txl prefix from symbols.Kaz Kylheku2016-05-071-23/+23
| | | | | | * genvim.txr: Let's not get rid of this just from the instructions comment, but from the internals. txl-* replaced with tl-*.
* Don't refer to .txl in install instructions.Kaz Kylheku2016-05-071-3/+3
| | | | | | * genvim.txr: "INSTALL-HOWTO" comment still talks about .txl files, an experimental suffix we didn't go with. Now fixed to .tl.
* Fix Vim syntax highlighting bugs.Kaz Kylheku2016-05-041-2/+2
| | | | | | | | * genvim.txr (txr_splicevar): This match must be contained. (txr_metanum): Must be contained in TXR, need not be contained in TXR Lisp. * txr.vim, tl.vim: Regenerated.
* Add missing txr words to syntax highlighting.Kaz Kylheku2016-01-191-1/+2
| | | | | | * genvim.txr: Add missing single, first, last and other output repeat modifiers. Removing rep, since it's scraped from the table registration in match.c.
* Syntax highlighting regression and omission.Kaz Kylheku2015-12-221-13/+14
| | | | | | | * genvim.txr: Use new mboundp to check for macros, and special-operator-p to detect operators. fboundp doesn't report them any more. Also, :postinit must be included among lispwords.
* Some missing exceptions to indentation rule.Kaz Kylheku2015-11-301-1/+2
| | | | | * genvim.txr: Indent new, lnew, meth, umeth and usel forms like function calls.
* Vim: better indentation for some forms.Kaz Kylheku2015-10-071-1/+7
| | | | | * genvim.txr: Some operators should indent like functions. We don't want these in lispwords.

* Don't scan C source code for Lisp symbols.Kaz Kylheku2015-09-101-33/+17
| | | | | | | | | | | | | | * eval.c (eval_init): Register package-alist, package-name and package-symbols intrinsics. * genvim.txr: Rather than scanning C sources for TXR Lisp symbols, iterate over the packages and their symbols, collecting anything which has a binding or is self-evaluating. To get the stdlib symbols, we trigger the autoloads by doing boundp queries on a few symbols. * txr.1: Document package-alist, package-name and package-symbols.
* Version 114.txr-114Kaz Kylheku2015-09-021-3/+3

* Support trailing semicolon after hex/octal characters.Kaz Kylheku2015-07-021-3/+4
| | | | | | | | | | | | | | | | * parser.l (%option): Remove nounput option since we need yyunput. (grammar): Rule for matching hex and octal escape in SPECIAL state recognizes optional semicolon. In 109 compatibility, this is pushed back into the stream, otherwise consumed. * txr.1: Updated documentation, including compat notes. * genvim.txr (txr_char): Include optional semicolon in match. Corrected some errors where 8 and 9 were being included as matches for octal digits. (txr_error): Default match for \x or \o not followed by digits.
* Handle escapes accurately in Vim syntax highlighting.Kaz Kylheku2015-07-021-5/+14

(dwim_set, dwim_del): New functions. * lib.h (sys_rplaca, sys_rplacd, dwim_set, dwim_del): Declared. * genvim.txr: Include place.tl in scan. * tests/010/seq.txr: The del operator test case no longer throws at run-time but at macro-expansion time, so the test case is simply removed. * tests/010/seq.expected: Updated output. * tests/011/macros-2.txr: Reset *gensym-counter* to zero, because the textual output of the test case includes gensyms, whose numberings fluctuate with the content of the new Lisp library material. * tests/011/macros-2.expected: Updated output.
* * unwind.c (unhandled_hook_s): New static variable.Kaz Kylheku2015-02-061-1/+2
| | | | | | | | | | | | | | | | | | | (uw_throw): In the unhandled case, check if *unhandled-hook* variable has a function, and use it instead of the default logic. If it's not a function, abort with an error message. Clear it so that if the hook function re-enters this code, it will not be used. Always exit now on unhandled exceptions; do not abort. (uw_late_init): New function. * unwind.h (uw_late_init): Declared. * lib.c (init): Call uw_late_init. * txr.1: Documented *unhandled-hook*. * genvim.txr: Scan the unwind.c file, since it has a reg_var now. * tl.vim, txr.vim: Updated.
