Add a small INI-style parser for *.theme files and wire it into the
/theme command so user themes living in directory "themes" inside the
WeeChat configuration directory can be applied (and inspected) without
ever being cached.
Parser (theme_file_parse in core-theme.c) accepts two sections:
[info]
name = "..." \ shown by /theme info; ignored for apply
description = "..." |
date = "..." |
weechat = "..." /
(unknown keys are ignored with a warning)
[options]
full.option.name = "value"
Surrounding single or double quotes around a value are stripped (same
rule used by the regular config file reader). The parsed result is a
heap-allocated t_theme; the caller frees with theme_free.
Resolution rule in theme_apply: if the path
"${weechat_config_dir}/themes/<name>.theme" is readable it is parsed
and used (file shadows any built-in of the same name); otherwise the
built-in registry is consulted. The transient t_theme is freed before
the final refresh, so user themes have no steady-state memory
footprint regardless of how many .theme files have accumulated.
/theme list now also scans the themes directory and appends user
files to the listing (each marked "(file)"). backup-*.theme are
hidden by default; pass "-backups" to include them.
/theme info <name> works for both sources: file path is shown when the
information comes from disk; "built-in (in-memory)" otherwise.
