- Fixed syntax highlighting for ksh93 namespace variables starting
with '${.'
- Added support for the alarm, eloop, fds, mkservice, pids, poll and
sha2sum builtins (which are indeed ksh93 builtins, albeit whether or
not they are available depends on the ksh release and the compiled
SHOPT options).
- Added support for the many Unix commands provided by ksh93's libcmd
as builtin commands (since these are general commands, scripts for
other shells like bash will also highlight these).
- The dumps for the sh_0{2,5,6,8,9}.sh were recreated due to this
change affecting commands those scripts call (e.g. 'wc').
- Enabled ${parameter/pattern/string} and friends for ksh syntax.
- Enabled case modification for ksh. See also:
https://github.com/ksh93/ksh/commit/c1762e03
- Enabled ;;& support for ksh. See also:
https://github.com/ksh93/ksh/commit/fc89d20a
- Added many special ksh variables using 93u+m's data/variables.c
as a reference.
If vim can't figure out which ksh release is in play using e.g.
the hashbang path, in such a case a generic default that enables
everything and the kitchen sink will be used. Otherwise, features will
be disabled if it's absolutely known a certain feature will not be
present. Examples:
- ERRNO is ksh88 specific, so that is locked to ksh88.
- Only 93u+m (assumed for generic) has SRANDOM, and only 93u+m
and 93v- have case modification support.
- 93u+ and 93v- have VPATH and CSWIDTH variables (the latter
is vestigal, but still present in the hardcoded variable table).
- 93v- and ksh2020 have (buggy and near unusable) implementations
of compgen and complete.
- Only mksh provides function substitutions, i.e. ${|command;}.
This took the better part of my day to implement. It seems to work well
enough though. (Also had to regenerate the dumps again while testing
it, as now there are dup scripts with mere hashbang differences, used
solely for testing syntax highlighting differences.)

This directory contains Vim scripts for syntax highlighting.
These scripts are not for a language, but are used by Vim itself:
syntax.vim Used for the ":syntax on" command. Uses synload.vim.
manual.vim Used for the ":syntax manual" command. Uses synload.vim.
synload.vim Contains autocommands to load a language file when a certain
file name (extension) is used. And sets up the Syntax menu
for the GUI.
nosyntax.vim Used for the ":syntax off" command. Undo the loading of
synload.vim.
The "shared" directory contains generated files and what is used by more than
one syntax.
A few special files:
2html.vim Converts any highlighted file to HTML (GUI only).
colortest.vim Check for color names and actual color on screen.
hitest.vim View the current highlight settings.
whitespace.vim View Tabs and Spaces.
If you want to write a syntax file, read the docs at ":help usr_44.txt".
If you make a new syntax file which would be useful for others, please send it
to the vim-dev mailing list <vim-dev@vim.org>. Include instructions for
detecting the file type for this language, by file name extension or by
checking a few lines in the file. And please write the file in a portable way,
see ":help 44.12".
If you have remarks about an existing file, send them to the maintainer of
that file. Only when you get no response send a message to the vim-dev
mailing list: <vim-dev@vim.org>.
If you are the maintainer of a syntax file and make improvements, send the new
version to the vim-dev mailing list: <vim-dev@vim.org>
For further info see ":help syntax" in Vim.
