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)
