Tackles the critical and high-impact findings from the in-PR review
of commit 7f01be5, plus one consistency fix (M1). All changes are
scoped to the same review branch (PR #12); no behavior changes
elsewhere.
Critical fixes
* C1 -- plugin/22_languages.lua: now does `local Config = require('config')`
at the top, matching every other `plugin/*.lua` file. Previously the
file referenced `Config` as a global, depending on `_G.Config` having
been initialized by `init.lua` before this file loaded. Fragile.
* C2 -- plugin/04_treesitter.lua: removed the hard `<CR>` ->
`smart_send.send_repl` mapping. Override `<CR>` from a per-buffer
`ftplugin/<lang>.lua` if you want enter-to-send behavior. R.nvim's
`<Plug>RDSendLine` (wired by `ftplugin/r.lua`) remains the default
for R files and is no longer silently clobbered.
High-impact fixes
* C3 -- plugin/27_image.lua: `image.setup({ backend = "kitty" })` ->
`backend = "auto"`. The previous value silently failed on every
terminal that is not Kitty. `"auto"` delegates detection to image.nvim.
* H1 -- plugin/10_keymap.lua: `_G.Config = Config` removed from this
file; `init.lua:2` remains the single source. Avoids drift between
two aliasing sites.
* H2 -- plugin/25_lsp.lua: `texlab = { single_file_support = true }`,
so single-file `.tex` buffers attach the LSP without lspconfig's
sometimes-brittle root_dir heuristic.
* H5 -- plugin/04_treesitter.lua: also drops `<S-CR>` from
`M.setup_keybindings` on the same principle as C2. `<S-CR>` was a
hard implicit override in both normal and insert mode, where it
collided with snippet and transient-state plugins.
Consistency fixes
* M1 -- plugin/01_lib.lua: `print(line)` in `Config.execute_lua_line`
switched to `vim.notify(line, vim.log.levels.INFO)`, matching the
print->notify cleanup in `plugin/04_treesitter.lua` from 7f01be5.

Local verification
1. `luac -p plugin/{22_languages,27_image,10_keymap,25_lsp,04_treesitter,01_lib}.lua`
2. `nvim --headless -u NONE -l tests/init.lua`
3. Open a R / quarto / tex buffer; verify `<CR>` is no longer hijacked
by `smart_send` and behaves like the filetype default.
For reviewers
* The text-object configuration in plugin/04_treesitter.lua's
textobjects block is unchanged. H4 (`@assignment.*` queries may not be
defined for R) is left for a follow-up with verification.
* yamlls GitHub-rawURL schema dependency (H3) is left intentionally --
vendoring the schemas is a separate decision.
* Tests (T1-T6 from the review) are deferred; no test infrastructure
exists beyond `tests/init.lua`.
Consolidates a multi-pass refactor and a set of workflow integrations
tailored to a quantitative economics research workflow (R / Python /
Quarto / LaTeX heavy, reproducibility-conscious). The existing terminal
setup is preserved (snacks.nvim was deliberately not adopted).
=== Structural refactors ===
* Replace the `_G.Config` global with a proper `require('config')` Lua
module. `_G.Config` is kept only as a backward-compatible alias.
* Split the monolithic `plugin/10_keymap.lua` into domain-specific
files under `lua/keymap/` (core, helpers, leader, terminal, repl).
* Harden `lua/nix_smart_send.lua` `send_repl`: only skip forward on
comment nodes, and return cleanly when there is no next sibling.
* Add a filetype-aware REPL dispatcher in `lua/keymap/repl.lua`:
pure R scripts -> R.nvim, .qmd/.Rmd chunks -> quarto.runner,
everything else -> vim-slime. Prefer `quarto.runner.run_line()`
when available and fall back to `run_cell()`.
* Add R Treesitter text objects (function / call / assignment) for
faster motion when sending code to the REPL.
* Add `+Send` and `+Debug` leader-clue groups for the new prefixes.
=== LSP and tooling ===
* Register `yamlls` for Quarto YAML frontmatter (`plugin/25_lsp.lua`).
* Register `texlab` and add `vimtex` for a real `.tex` workflow
(`plugin/25_lsp.lua` + new `plugin/28_latex.lua`).
* Wire `nvim-dap` with an R adapter backed by `vscDebugger`
(new `plugin/26_dap.lua`, gated to the `r` cat).
* Add `image-nvim` for in-editor plots, gated to the `r`/`markdown`
cats (new `plugin/27_image.lua`).
* Wire `lintr` into `nvim-lint` for R / Quarto (`plugin/22_languages.lua`).
* Add Treesitter parsers for `stata`, `matlab`, `bibtex` for completeness.
=== Nix updates ===
* Pin `python313Packages.pylatexenc` -> `python3Packages.pylatexenc`
so the markdown cat survives nixpkgs Python default shifts.
* Add `texlab`, `imagemagick`, `luaPackages.magick` to the markdown
cat so `image.nvim` has a working backend.
* Add `vscDebugger` and `lintr` to the R package list.
=== Misc ===
* Prefer the R.nvim v1.0 Lua API (`require('r.run').send_line()` /
`send_selection()`); keep `<Plug>` mappings as a fallback so older
downstream builds don't regress.
* Use `alejandra` (already installed) as the nixd / nil_ls formatter.

Local verification before merge:
1. `nix flake check --no-build`
2. `nvim --headless -u NONE -l tests/init.lua`
3. Open a `.qmd` -> confirm `yamlls` attaches and `image.nvim` renders.
4. Open an `.R` -> `<leader>db`, `<leader>dc` confirm DAP loads.
5. Open a `.tex` -> confirm `texlab` + `vimtex` are active.
