Thanks to Joerg Desch for explaining how it needs to work.
Note: this breaks the plugin API for indentation editor_prefs.
Add separate Width indent pref (as well as the Tab Width pref).
Add 'Tabs & Spaces' Indent Type radio option pref.
Add 'Tabs and Spaces' Document menu indent option.
Note: Tabs & Spaces cannot be detected (yet) when opening files;
default file templates still only use tabs.
Set 'Detect from file' indent type setting insensitive when Tabs &
Spaces is set.
Don't change per-document auto-indent setting after changing default
auto-indentation type.
- API changes:
Add GeanyIndentPrefs struct from some GeanyEditorPrefs fields.
Replace GeanyIndentPrefs::use_tabs with GeanyIndentType field 'type'.
Add editor_get_indent_prefs() to the API, which should be used to
get the right settings for a document/editor instead of reading
any struct fields. This could also support project/filetype
indentation prefs quite easily.
- Core code changes:
Move toggle_prefs to a function toggle_items_foreach(), which takes
a PREF_DISPLAY or PREF_UPDATE argument. This means the PrefEntry
array can contain runtime fields, so can read pointer contents.
Add pref_item_callbacks array of functions to call;
toggle_items_foreach(), spin_items_foreach(), radio_items_foreach(),
combo_items_foreach().
Update keyfile.c to use foreach-style functions for SettingEntry
arrays, like the new PrefEntry code in prefs.c.
Add get_indent_size_after_line() to replace get_indent() for
clarity, and to fix Tabs & Spaces auto-indentation > basic.
Remove opening-brace indent code from get_indent() as it's now in
get_brace_indent().
Change editor_close_block() to use sci_get_line_indentation() for
clarity.
Make editor_close_block() static.
Add editor_init().
