Refactor the theme registry to store one sub-table per contributor
instead of a single merged hashtable. Each registered theme now holds
a linked list of t_theme_contribution entries:
struct t_theme_contribution {
struct t_weechat_plugin *plugin; /* NULL = core */
const void *script; /* NULL for non-script */
struct t_hashtable *overrides;
...
};
Identity of a contributor is the (plugin, script) pair:
- (NULL, NULL) -> core (theme_builtin_init)
- (plugin, NULL) -> plugin-level contribution
- (plugin, script) -> individual script (filled in by next commit)
theme_register is now (plugin, script, name, overrides). It searches
the existing contributions for a matching (plugin, script) and merges
the new overrides into it; otherwise it appends a fresh contribution.
The public macro weechat_theme_register(name, overrides) still takes
two args - it now expands to pass weechat_plugin and NULL for script.
theme_apply iterates contributions in list order, calling
config_file_option_set for each entry; later contributions naturally
win for duplicate keys.
Two new internal helpers prepare for the lifecycle work in the next
two commits:
- theme_unregister_plugin (plugin): drops every contribution owned
by that plugin (with script == NULL).
- theme_unregister_script (plugin, script): drops every contribution
owned by that script.
Neither is called yet; the auto-purge wiring lands in commits 24
(plugin_unloaded signal) and 25 (script API + script-unload hook).
Other touched code:
- core-theme-builtin.c switches to theme_register (NULL, NULL, ...).
- core-command.c /theme info uses theme_overrides_count helper
instead of reaching into theme->overrides (which no longer
exists).
- WEECHAT_PLUGIN_API_VERSION bumped to 20260527-01 (function-pointer
signature change).
Two new tests cover the new semantics:
- UnregisterByOwner: registers four contributions from distinct
(plugin, script) pairs, then prunes by plugin and by script,
asserting per-contribution removal.
- RegisterMergesPerContributor: two successive register calls from
the same (plugin, script) merge into a single contribution with
later keys overriding earlier ones.
Existing tests are updated to use the new theme_register signature,
theme_overrides_count, and theme_get_override (replacing direct
access to theme->overrides->items_count and hashtable_get on
theme->overrides). No plugin or script call sites change - the
public weechat_theme_register macro keeps the same shape.
Add a small core-theme-builtin.c module containing the core
contribution to the "light" theme: 33 overrides for
"weechat.bar.{status,title}.color_*" and "weechat.color.*" tuned for
light-background terminals.
theme_builtin_init() builds a hashtable from the static entry table and
calls theme_register("light", overrides), then frees the temporary
hashtable. It is called once from weechat_init right after theme_init.
Calling it twice is a no-op (the registry merges identical keys).
Default option values are NOT changed. Existing configs render exactly
as before; users opt in with "/theme apply light".
Add TEST(CoreTheme, BuiltinInit) covering:
- the "light" theme is absent before theme_builtin_init();
- it is present after, with >= 30 overrides;
- three spot-checked values match the source table;
- calling theme_builtin_init() a second time does not change the
override count.
Plugins contribute their own "light" overrides via weechat_theme_register
in subsequent commits.
