Re-expose it ourselves by probing clang-unwrapped's main and python outputs (bin/ first, then the legacy share/clang/ layout) and installing the first hit at $out/bin/run-clang-tidy. 2026-05-22T09:41:23Z sommerfeld sommerfeld@sommerfeld.dev 2026-05-22T09:41:23Z urn:sha1:668b9846a6eccb16a619f57d305f1bd6bdaeb7bc tuicr (TUI git-change reviewer) isn't packaged in nixpkgs, so pull it as a flake input with an overlay exposing pkgs.tuicr. The companion claude-code skill lives in dot_claude/skills/tuicr/ (separate commit). 2026-05-22T09:41:22Z sommerfeld sommerfeld@sommerfeld.dev 2026-05-22T09:41:22Z urn:sha1:7968c511c3c49c98c5b2217240058e9f64c79a68 Interactive python REPL.

Resolution: - nix/common.nix: drop the entire deployment block, drop the my.dotfilesPath option, drop the let..in dotfiles/link helpers. Module is now deployment-agnostic: only installs packages. - nix/host.nix: drop my.dotfilesPath; explicit comment that chezmoi owns dotfile deployment on the host. - nix/vm.nix: gains everything previously in common.nix's deployment block — xdg.configFile (nvim/zellij/zsh/git/ghostty/direnv), home.activation.sshConfig, home.file.".zshenv". The 'dotfiles' let-binding (= $HOME/.local/share/dotfiles) and 'link' helper move here too, since they're vm-only now. Host runbook unchanged (`just sync`); first run after pulling will just be a no-op nix-switch instead of a backup-file storm. 2026-05-20T12:56:10Z sommerfeld sommerfeld@sommerfeld.dev 2026-05-20T12:56:10Z urn:sha1:58f2d61be4c55c7cf7bdbb12f3fed6794e7481b5 - common.nix hardcoded the runtime dotfiles checkout to ~/.local/share/dotfiles, which is correct for the remote-dev VM but not the Arch host (where the canonical clone lives at ~/dotfiles). ssh activation was failing with 'cannot stat /home/sommerfeld/.local/share/dotfiles/private_dot_ssh/config' on every host nix-switch. Promote the path to a typed option (config.my.dotfilesPath) and set it from each profile: nix/host.nix -> $HOME/dotfiles nix/vm.nix -> $HOME/.local/share/dotfiles common.nix now wraps its config in 'config = { ... }' so the options can sit alongside. - dockerfile-language-server-nodejs was renamed in nixpkgs to dockerfile-language-server; pick up the new name to silence the evaluation warning (the rename will eventually become a hard error). 2026-05-20T12:56:10Z sommerfeld sommerfeld@sommerfeld.dev 2026-05-20T12:56:10Z urn:sha1:3bc07df183cba19a9824ccf074041347a8bd1490 nodePackages was removed wholesale from nixpkgs; everything that lived under it must be referenced via its top-level name or dropped. - prettier: moved nodePackages.prettier -> prettier (top-level alias). - jsonlint: not available at top level. Dropped from nix/common.nix AND from the nvim-lint and conform-nvim configs in dot_config/nvim/lua/plugins/lsp.lua. jsonls already provides schema-aware diagnostics; jq still handles formatting. The jsonlint redundancy is acceptable to lose. - github-copilot-cli (1.0.40 in nixpkgs): buildNpmPackage derivation doesn't redirect HOME during npm postinstall, so it fails with EACCES on /var/empty/.cache on Determinate nix. Removed; install manually from https://github.com/github/copilot-cli into /usr/local/bin/ as before (current host already has it there). 2026-05-20T12:56:10Z sommerfeld sommerfeld@sommerfeld.dev 2026-05-20T12:56:10Z urn:sha1:40d8fd056bef4526acbe38a9b6ff98fc0c3fd8c9 - gh-actions-language-server is an npm package (lttb/gh-actions-language-server) not packaged in nixpkgs. Removed from nix/common.nix and from the vim.lsp.enable list in dot_config/nvim/lua/plugins/lsp.lua. Restore later via a per-project flake.nix if working on a workflows-heavy repo. - just runs recipes with a sanitized env where $USER may be unset; home-manager's activation script dereferences it unconditionally and fails with 'USER: unbound variable'. Export USER (and HOME for symmetry) at the top of the nix-switch recipe.
