support lookups via language servers (LSP)HEADmaster-fmsbw-cimaster
* 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.
