From b8a77260f8cf773a2187b436443341095d63d3e0 Mon Sep 17 00:00:00 2001 From: Chiarandini Date: Mon, 31 Aug 2026 21:58:34 -0400 Subject: [PATCH 01/20] feat(lsp): install the tools a bundle declares, not just its servers `ensure_installed` has always fetched language servers, but nothing did the same for the other three toolchain layers. A bundle could name `black` in `formatters_by_ft` or register a `codelldb` adapter and the reader would still be one manual :MasonInstall away from the feature existing, with only :checkhealth to say so. Formatting silently fell back to the LSP; debugging failed at the moment was pressed. conform already carried a private `mason_install` list for exactly this. This extracts it to util/mason_install.lua so conform, nvim-lint and nvim-dap share one implementation and one opt-out, and makes core install what core claims: prettierd and shfmt join stylua, and `python = { "black" }` moves out to the python bundle, since core should not claim a filetype it will not install for. Enabling a bundle is the opt-in, the same bargain `ensure_installed` already strikes. `vim.g.noethervim_auto_install = false` declines it, for a toolchain managed by Nix, system packages or a project venv where a second copy under Mason is redundant at best. nvim-dap gets `opts_extend` and no seed table: lazy replaces arrays rather than merging them, and the stock init.lua imports languages/ before tools/, so a table on this fragment merges last and silently erases every adapter the language bundles appended. --- doc/noethervim.txt | 22 ++++++++++ doc/tags | 1 + init.lua.example | 6 +++ lua/noethervim/bundles/tools/debug.lua | 25 +++++++++-- lua/noethervim/health.lua | 7 ++++ lua/noethervim/plugins/lsp.lua | 33 ++++++++------- lua/noethervim/util/mason_install.lua | 57 ++++++++++++++++++++++++++ 7 files changed, 130 insertions(+), 21 deletions(-) create mode 100644 lua/noethervim/util/mason_install.lua diff --git a/doc/noethervim.txt b/doc/noethervim.txt index f06eb0d..08be09f 100644 --- a/doc/noethervim.txt +++ b/doc/noethervim.txt @@ -1203,6 +1203,28 @@ can be turned off with a single flag in your init.lua, set before With the flag set, `nvim` opens straight into an empty buffer.

Adding a language meant remembering both, and nobody did, so rf answered "No runner for filetype: rust" inside a cargo crate. util/run.lua now holds project markers plus file and project commands for fifteen filetypes, and both runners read it. rp is new: run the project around the buffer (cargo, go.mod, npm, Maven, make), distinct from rf for the file. Rust runs `cargo run` inside a crate and rustc on a loose file; java uses the JDK 11+ single-file launcher, because javac plus `java -cp ` fails for any class in a package. Also moves code_runner off the refactor namespace: RR becomes rc and RT becomes rT, so R is refactor only, which is what which-key and the vimdoc prefix listing already claimed. Both are declared in `keys` because that is the only load trigger, and RT created inside `config` did not exist until RR had been pressed. --- lua/noethervim/bundles/tools/task-runner.lua | 105 +++++++------ lua/noethervim/plugins/code-runner.lua | 90 ++++++++--- lua/noethervim/util/run.lua | 155 +++++++++++++++++++ 3 files changed, 275 insertions(+), 75 deletions(-) create mode 100644 lua/noethervim/util/run.lua diff --git a/lua/noethervim/bundles/tools/task-runner.lua b/lua/noethervim/bundles/tools/task-runner.lua index 3ca85cb..19ea321 100644 --- a/lua/noethervim/bundles/tools/task-runner.lua +++ b/lua/noethervim/bundles/tools/task-runner.lua @@ -1,8 +1,9 @@ ---@bundle task-runner ---@desc run builds and project tasks from the editor ---@about overseer.nvim runs and tracks tasks, compiler.nvim wraps it in a ---- project compiler UI, and rf runs the current file in a way ---- that respects filetype and version managers. +--- project compiler UI, and rf and rp run the current +--- file or the project around it, respecting filetype, project markers +--- and version managers. ---@requires note="your project build tool" --- why="overseer and compiler.nvim shell out to it" --- install="make, cargo, latexmk, npm, ... whatever the project uses" @@ -14,27 +15,15 @@ -- compiler.nvim: project compiler UI (:CompilerOpen, :CompilerToggleResults) -- -- Keymaps: --- rf run current file (filetype-aware, version-manager-aware) +-- rf run the current file +-- rp run the project around it (cargo, go.mod, npm, Maven, make) -- toggle task list --- Filetype → interpreter command. --- For commands with subcommands (e.g. "go run"), the first word is resolved --- through version managers while the rest is preserved. -local runners = { - python = "python3", - lua = "lua", - javascript = "node", - typescript = "tsx", - go = "go run", - sh = "sh", - bash = "bash", - zsh = "zsh", - ruby = "ruby", - julia = "julia", - perl = "perl", - r = "Rscript", - php = "php", -} +-- What each language runs comes from `noethervim.util.run`, shared with core's +-- code_runner so a language is taught once.

Nothing did, which made the bundle's own claim that "it starts on the first .java buffer" false. jdtls is now started from the bundle with a workspace directory per project; it keeps an index there, and pointing two projects at one directory corrupts it. jdtls itself comes through `ensure_installed` instead of being a manual :MasonInstall, and the java parser and google-java-format are declared. Debugging needed more than a Mason package. Java is the one language here whose debug adapter is not a separate process: java-debug-adapter is a jar loaded into jdtls, which then serves DAP over the language server. So there is no dap.adapters.java to define; the jars go through `init_options.bundles`, and `setup_dap()` plus `setup_dap_main_class_configs()` run on attach.

Both of its result paths are broken. The cargo-test path scrapes stdout and attributes the process exit code, 101 whenever anything fails, to every discovered position; the nextest path looks for `` while nextest emits a self-closing ``. Installing cargo-nextest therefore does not help. neotest-rust owns the adapter now and reports 1 and 1. The bundle still requires rustaceanvim.neotest, which is load-bearing rather than leftover: :RustLsp testables picks its executor by asking whether that module is in package.loaded, and when it is, the command resolves a neotest position id and calls neotest.run.run(id) instead of opening a terminal. Both build the same :::: id. Two other fixes here. rustaceanvim loads eagerly, per its own guidance: `ft = "rust"` never reached its ftplugin/toml.lua, so saving a Cargo.toml did not reload the workspace unless a Rust buffer had been opened first. And a .rs file outside a crate starts rust-analyzer detached, where cargo drives rustc with nightly-only flags and every save answered with a compiler backtrace on a stable toolchain; checkOnSave is now off for a client with no project root. Declares the rust and toml parsers, rustfmt, and codelldb for the debug bundle. Corrects the header, which told users to override with `opts = { ... }`; rustaceanvim has no setup(), so lazy would have called nil. --- lua/noethervim/bundles/languages/rust.lua | 153 ++++++++++++++++++---- 1 file changed, 127 insertions(+), 26 deletions(-) diff --git a/lua/noethervim/bundles/languages/rust.lua b/lua/noethervim/bundles/languages/rust.lua index eabd6b2..5b83d60 100644 --- a/lua/noethervim/bundles/languages/rust.lua +++ b/lua/noethervim/bundles/languages/rust.lua @@ -3,65 +3,166 @@ ---@about rustaceanvim goes past plain rust-analyzer with macro expansion, --- runnables and debuggables, the crate graph, hover actions and --- structural search-replace.

Every one of those reads as correct in the bundle source. tests/capability.sh grades all seven language bundles against the eight checkpoints in the language-bundle contract, in an isolated NVIM_APPNAME with its own XDG root: a server attaches, treesitter parses, the formatter changes the buffer to known text, a deliberately broken symbol produces a diagnostic on the line it was injected on, one passing and one failing test are reported as one of each, a debug session stops on a breakpoint and reads a local, and the file and project both run with asserted stdout. Nightly rather than per PR, because it provisions Rust, Go, Python, a JDK, Node and LLVM and then a Mason package set on top. No TeX: gigabytes for one bundle, and the harness gates each row on its toolchain, so latex reports UNCOVERED there instead of failing. Only the harness leaves tests/, not the rest of the private suite. The exclusion moves to tests/* because git does not descend into an excluded directory, so a negation inside one never applies. Every cell resolves to PASS, FAIL, N/A, a tracked GAP, or UNCOVERED when the toolchain is genuinely absent; none may be skipped.

The web test cell was flaky: green alone, red in --all, same fixture, no code change. web-dev registers two neotest adapters, jest and vitest, and only one owns a given project. The poll accepted the first adapter reporting `total > 0` and `running == 0`, which the idle one satisfies exactly -- it discovered the positions and ran nothing. Whichever adapter_ids() yielded first decided the outcome. Now the positions must be resolved, not merely not-running. "Not in progress" and "finished" are different claims, and on any multi-provider surface the difference is a coin flip rather than a visible failure. When a toolchain was absent, only four of the eight cells were recorded and the other four vanished from the report, which is the one thing the coverage rule forbids. All eight now report UNCOVERED. The web fixture's node_modules is not committed, so a clean checkout had no vitest and the test cell would have failed for a missing tool rather than reporting UNCOVERED. Provisioning installs it, and warms vitest so the graded run measures the adapter rather than the first transform. Also drops the vendored doctest.h in favour of fetching it: 363 KB of someone else's header for one fixture is not worth carrying. --- tests/capability.sh | 17 +++++++++++++++++ tests/capability_assert.lua | 15 ++++++++++++++- 2 files changed, 31 insertions(+), 1 deletion(-) diff --git a/tests/capability.sh b/tests/capability.sh index 4ad2cf2..8e85d11 100755 --- a/tests/capability.sh +++ b/tests/capability.sh @@ -162,6 +162,23 @@ run_one() { # run, and the symptom is an adapter that discovers the tests and reports # no results at all -- indistinguishable from a broken adapter.

The `build` step compiled `vsDebugServerBundle`, which is the VS Code flavour: it expects the editor to answer a `startDebugging` reverse request and run the debuggee in a child session. `dapDebugServer` is the standalone-DAP entry point and speaks to a plain DAP client directly. The symptom was a debugger that did nothing. A session started, breakpoints were acknowledged, `configurationDone` was answered, and then nothing stopped, `stopOnEntry` included, because the child session that would own the debuggee was never created. nvim-dap advertises `supportsStartDebuggingRequest` and implements the handler for both adapter types, so both ends were capable and the request still never arrived. Mason's `js-debug-adapter` packages the DAP release, so the adapter now comes through the same `mason_install` path as codelldb, debugpy and delve. That retires a ~430 MB `microsoft/vscode-js-debug` checkout whose `build` ran `npm i` at install time, and `mxsdev/nvim-dap-vscode-js`, which is unmaintained and no longer needed. Verified before the rewrite rather than after: pointing an adapter at a downloaded `dapDebugServer.js` stopped on a breakpoint on the first attempt, in the same environment where every other approach hung.

The cell passed locally only because cargo-nextest had been installed by hand while investigating something else. Now declared in the bundle's `@requires` and gated on in the matrix, so its absence reads as UNCOVERED rather than as a broken adapter. **java: jdtls needs a JDK 21.** On the runner's 17 it does not start at all, which presents as "the Java bundle attaches no language server" -- the same symptom this branch fixed for a different reason. The bundle said "17 or newer", which is the version a project may target, not the one jdtls itself runs on. **c and cpp: a breakpoint in the prologue.** `add` was a one-line function and the breakpoint sat on its signature, so it bound before the parameters reached their stack slots: Linux read `a=32767` where macOS happened to read 40. The fixtures now have a body statement to stop on, which is what a breakpoint should target anyway. **A failed build reported as a broken adapter.** When a `prepare` command fails, the test cell said "no results within budget", blaming the adapter for something that happened before it ran. It now reports the command, its exit code and its output. --- .github/workflows/capability.yml | 10 ++++++-- README.md | 2 +- docs-site/src/content/docs/guides/bundles.md | 6 +++-- lua/noethervim/bundles/languages/java.lua | 5 ++-- lua/noethervim/bundles/languages/rust.lua | 4 +++ tests/capability_assert.lua | 27 +++++++++++++++----- tests/fixtures/lang/c/main.c | 5 +++- tests/fixtures/lang/cpp/main.cpp | 5 +++- 8 files changed, 49 insertions(+), 15 deletions(-) diff --git a/.github/workflows/capability.yml b/.github/workflows/capability.yml index bdf9dde..57d0d5c 100644 --- a/.github/workflows/capability.yml +++ b/.github/workflows/capability.yml @@ -69,7 +69,11 @@ jobs: # run honestly instead of turning it red for the wrong reason -- but the # point of installing them is that UNCOVERED should stay empty. - name: Rust toolchain - run: rustup component add rust-analyzer rustfmt + run: | + rustup component add rust-analyzer rustfmt + # neotest-rust drives `cargo nextest`, not `cargo test`. + curl -fsSL https://get.nexte.st/latest/linux \ + | tar zxf - -C "${CARGO_HOME:-$HOME/.cargo}/bin" - uses: actions/setup-go@v5 with: { go-version: "stable" } @@ -78,7 +82,9 @@ jobs: with: { python-version: "3.12" } - uses: actions/setup-java@v4 - with: { distribution: temurin, java-version: "17" } + # 21, not 17: jdtls itself runs on 21, and on 17 it does not start at + # all, which reads as "the Java bundle attaches no language server". + with: { distribution: temurin, java-version: "21" } - uses: actions/setup-node@v4 with: { node-version: "22" } diff --git a/README.md b/README.md index ea8eb0f..e2b9965 100644 --- a/README.md +++ b/README.md @@ -123,7 +123,7 @@ header. - `c-cpp` needs compile_commands.json - `go` needs Go toolchain -- `java` needs a JDK +- `java` needs a JDK 21 or newer - `latex` needs latexmk - `python` needs Python 3 - `rust` needs rust-analyzer, Cargo diff --git a/docs-site/src/content/docs/guides/bundles.md b/docs-site/src/content/docs/guides/bundles.md index 617b510..764d544 100644 --- a/docs-site/src/content/docs/guides/bundles.md +++ b/docs-site/src/content/docs/guides/bundles.md @@ -64,8 +64,8 @@ jdtls needs workspace management and jar paths that plain lspconfig cannot suppl Requires: -- **a JDK**: jdtls will not start without one -
