Vendored from upstream, pinned by commit (see debian/extra/README.source): - gitstatus, gitopen, fontconfig, open_ext, select_colorscheme, smoothcaret, nerdicons (font mapping patched to DATADIR, Ships the Symbols Nerd Font Mono TTF, SIL OFL 1.1) - lite-xl-lsp (complete LSP client; idle until a language server is configured) plus the lite-xl-widgets library it requires - 104 language syntax plugins (none duplicate the nine bundled in core) settings GUI left out upstream is broken: it requires a libraries.widget.fonts widget that does not exist in lite-xl-widgets at any revision. Co-developed-with: ZCode (Z.ai)

["pattern"] field:
|
|
Describes a syntax pattern, this is done with Lua Patterns
|
|
you can learn it works here: https://www.lua.org/manual/5.4/manual.html#6.4.1
|
|
|
|
The pattern can be a string or a table, when is a string, then is just a
|
|
pattern that match everything, when is a table, then it follows this
|
|
logic:
|
|
{ range_start_pattern, range_end_pattern [, escape_character] }
|
|
|
|
The matched range_start_pattern and range_end_pattern text will be highlighted, but the
|
|
text between them will not.
|
|
|
|
["syntax"] field:
|
|
Optional field, when set, the text between matched ranges will use syntax from another language,
|
|
a good common known example of this is using javascript syntax inside a `script` element:

|
|
|
|
["type"] field:
|
|
Set the style that should be used, this is defined on the "style" file from
|
|
the lite-xl's source, at "data/core/style.lua".
