Its README positions the server as an editor-agnostic way to give fish users a consistent development environment rather than depending on each editor's local fish support. ### Adoption history fish-lsp is packaged for multiple developer workflows: the official README documents npm, yarn, pnpm, Nix, Homebrew, conda, mamba, standalone GitHub release binaries, and source builds. It also links client configuration examples and nvim-lspconfig integration, which is a strong signal that adoption is editor-driven. ### How it is used A normal setup installs the `fish-lsp` binary, configures an editor language client to run `fish-lsp start` for fish files, and optionally installs shell completions with `fish-lsp complete > ~/.config/fish/completions/fish-lsp.fish`. ### Why package nerds care For package nerds, fish-lsp is notable because it turns fish from an interactive shell with nice built-ins into a language that participates in the modern LSP/editor tooling stack. It also has unusually broad distribution paths for a young shell-specific tool. ### Timeline - 2022: GitHub repository created. - 2025: 1.0.x releases established regular packaged releases. - 2026: 1.1.4 published, with releases continuing through GitHub and package managers. ### Related projects - Related projects include fish shell, the Language Server Protocol, editor LSP clients, nvim-lspconfig, and fish completion tooling. ### Sources - - - ## Security Notes generalized runtime or code generation signal. - **Geiger risk:** yellow / medium - generalized runtime or code generation signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** fish-lsp - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Nix - fish-lsp: normalized package name match | nixpkgs package indexes: pkgs/by-name/fi/fish-lsp/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Related links - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [node](https://www.automicvault.com/pkg/brew/node/) - Runtime dependency declared by Homebrew. - [fish](https://www.automicvault.com/pkg/brew/fish/) - Build dependency declared by Homebrew. - [efm-langserver](https://www.automicvault.com/pkg/brew/efm-langserver/) - Shares av.db curated category or tags: cli, developer-tools, editor-integration, formatting, language-server. - [codebook-lsp](https://www.automicvault.com/pkg/brew/codebook-lsp/) - Shares av.db curated category or tags: cli, developer-tools, editor-integration, language-server, lsp. - [dhall-lsp-server](https://www.automicvault.com/pkg/brew/dhall-lsp-server/) - Shares av.db curated category or tags: cli, developer-tools, editor-integration, language-server, lsp. - [gopls](https://www.automicvault.com/pkg/brew/gopls/) - Shares av.db curated category or tags: cli, developer-tools, editor-integration, language-server, lsp. - [jq-lsp](https://www.automicvault.com/pkg/brew/jq-lsp/) - Shares av.db curated category or tags: cli, developer-tools, editor-integration, language-server, lsp. - [pkl-lsp](https://www.automicvault.com/pkg/brew/pkl-lsp/) - Shares av.db curated category or tags: cli, developer-tools, editor-integration, language-server, lsp. - [python-lsp-server](https://www.automicvault.com/pkg/brew/python-lsp-server/) - Shares av.db curated category or tags: cli, developer-tools, editor-integration, language-server, lsp. - [terraform-ls](https://www.automicvault.com/pkg/brew/terraform-ls/) - Shares av.db curated category or tags: cli, developer-tools, editor-integration, language-server, lsp. - [texlab](https://www.automicvault.com/pkg/brew/texlab/) - Local metadata places this package in an adjacent workflow.
