From 44f5bf677282308b959411c416da2b5b08db2062 Mon Sep 17 00:00:00 2001 From: Robin Haberkorn Date: Sun, 2 Aug 2026 15:24:45 +0200 Subject: support lookups via language servers (LSP) * The main interface is the `FT` command. `FT` was an undocumented Video TECO command for etags/ctags lookups. I don't want to exactly copy its interface, though. * `FT` allows looking up symbol names, definitions and references. * ctags will be supported via ctags-lsp. LSP support is more powerful though and works without regenerating TAGS files all the time. The LSP will also allow you to customize auto-completions using SciTECO itself (i.e. by writing a language server in SciTECO). * For multiple results, `FT$` can be used to cycle through results - this should mimic repeated `S$` or `N$`. * `:FT...$` does a fuzzy search. IMHO it's not important to return a status integer instead. `FT` will only really be used in interactive mode. * Document synchronization is supported via hooks from ring.c and via Scintilla notifications. * Currently, the LSP communication is based on blocking GIOChannels. This means that a misbehaving hanging server could "lock up" the entire editor (FIXME). Only on ncurses you can always kill the subprocess by pressing CTRL+C. We need helper functions in spawn.c to read and write with interruptions. * The textDocument/didChange notification transmits not only all edits, but all files' contents as well during initial synchronization. Therefore it is optimized to write and JSON-escape data without copying them around in memory and without destroying the buffer gap. * Use $SCITECO_LSP to configure the language server. You can also use `tee` to capture stdin and stdout. Perhaps $SCITECO_LSP should be saved in .teco_session, so you can change it between projects? * $SCITECO_LSP_ROOT is used to point to the project's root directory. session.tes will set it up automatically. --- lib/session.tes | Bin 3180 -> 3299 bytes 1 file changed, 0 insertions(+), 0 deletions(-) (limited to 'lib/session.tes') diff --git a/lib/session.tes b/lib/session.tes index 845db25..6f3c7cc 100644 Binary files a/lib/session.tes and b/lib/session.tes differ -- cgit v1.2.3
