nvim-treesitter's :TSInstall reloads the parsers module from source
(package.loaded['nvim-treesitter.parsers'] = nil), which wipes runtime
config modifications. The old get_parser_configs() approach no longer
works for registering custom parsers with :TSInstall.
New approach:
- The mason build script now compiles parser.c into parser.so during
:MasonInstall tia-lsp (requires cc/gcc)
- The plugin's setup_syntax finds parser.so via:
1. opts.ts_parser_path (explicit override)
2. Mason package dir (resolved from exepath('tia-lsp'))
3. ~/dev/tia-lsp/parser.so (local dev fallback)
- Loads it with vim.treesitter.language.add('scl', { path = parser.so })
- Starts highlighting via vim.treesitter.start(bufnr, 'scl') in the
FileType autocmd
- Falls back to notifying the user if no parser.so is found
- Still registers with nvim-treesitter's parsers table as best-effort
for :TSInstall support (won't survive reload, but works in-session)
Change the default ts_parser_url from the local file:// path to the
Gitea-hosted tia-lsp repository, so :TSInstall scl works out of the
box after the repo split.
Rename the project from scl_lsp to tia_lsp to future-proof for additional
TIA Portal languages (STL/AWL, LAD, FBD). The 'scl' language name is kept
as-is for the SCL filetype and tree-sitter parser; future languages get
their own names (stl, lad, fbd).
Project-wide changes:
- lua/scl_lsp/ → lua/tia_lsp/ (plugin entry point)
- lua/scl/ → lua/tia/ (language modules, shared across TIA langs)
- require('scl.*') → require('tia.*')
- require('scl_lsp') → require('tia_lsp')
- LSP client name: 'scl_lsp' → 'tia_lsp'
- Diagnostic source: 'scl_lsp' → 'tia_lsp' (src/diagnostics.lua)
- package.json name: 'scl-language-server' → 'tia-lsp'
lua/tia_lsp/init.lua:
- Add vim.fn.exepath('tia-lsp') detection so the plugin prefers the
mason-installed executable and falls back to { 'lua', server_path }
for manual installs.
- Add opts.ts_parser_url to configure the tree-sitter parser source.
- Remove hardcoded ~/dev/scl_lsp paths in favor of ~/dev/tia-lsp and
the new ts_parser_url option.
Cleanup:
- Delete lua/tia/init.lua (dead code, unreferenced duplicate of tia_lsp).
- Delete scl_lsp.sh (replaced by the mason-installed bin/tia-lsp wrapper).
- Update README.md and AGENTS.md to reflect the two-repo split
(tia-lsp server + tia-lsp.nvim plugin) and document Mason installation.
Unchanged (intentional):
- grammar.js, src/grammar.json, src/parser.c: tree-sitter language name
remains 'scl' (it's the language, not the project).
- Filetype patterns ('scl', 'udt', 'db') in autocmds.
- :SCL* command names (per-filetype prefix; future :STL* etc.).
Tests pass with the same pre-existing failures as before the rename
(formatter VAR_INPUT test, udt_parser line 199 const-variable bug,
plc_json reference-project-missing). No new failures introduced.
