Language Server for RPM spec files

RPM Spec File Language Server

This is a proof of concept implementation of a server implementing the Language Server Protocol for RPM Spec files.

Please share your feature requests with us by opening an issue, creating a discussion or chat with us on matrix in #rpm-spec-language-server:matrix.org.

Supported LSP endpoints

• autocompletion of macro names, spec sections and preamble keywords

• jump to macro definition

• expand macros on hover

• breadcrumbs/document sections

Requirements

• Python >= 3.11

• poetry

Running the server

• Install the dependencies via poetry install

• Launch the server in tcp mode (binds to `127.0.0.1:2087 by default) via poetry run rpm_lsp_server

Alternatively, you can build the python package, install the wheel and run the module directly:

poetry build
pip install --user dist/rpm_spec_language_server-*.whl
python -m rpm_spec_language_server

The server requires the spec.md file. It can either use the locally installed copy from the rpm package or (if the documentation has not been installed) from a locally cached version in ~/.cache/rpm/spec.md.

Clients

VSCode

A very simple VSCode client is available in clients/vscode/. Building requires nodejs and the npm package manager:

$ npm install
$ npm run package

Install the created rpm-spec-language-server-$VERSION.vsix and launch the language server in tcp mode.

vis with vis-lspci

Add to your ~/.config/vis/visrc.lua this code:

lsp = require('plugins/vis-lspc')
lsp.ls_map['rpmspec'] = {
    name = 'RPMSpec',
    cmd = 'python3 -mrpm_spec_language_server --stdio'
}

Neovim with built-in LSP client

local lspconfig = require("lspconfig")
local util = require("lspconfig.util")
local configs = require("lspconfig.configs")
configs.rpmspec = {
    default_config = {
      cmd = { 'python3', '-mrpm_spec_language_server', '--stdio' },
      filetypes = { 'spec' },
      single_file_support = true,
      root_dir = util.find_git_ancestor,
      settings = {},
    },
    docs = {
      description = [[
  https://github.com/dcermak/rpm-spec-language-server

  Language server protocol (LSP) support for RPM Spec files.
  ]],
    },
}

lspconfig["rpmspec"].setup({})
