languages layer#

The languages layer is in charge of loading languages layers. These usually provide language-specific features such as:

  • a language server;
  • Tree-sitter parsers-based functionalities;
  • language-specific additional plugins.

Configuration#

A list of names of languages layers as strings. The order is not relevant.

Individual language layers need to be listed among the standard ones only when you want to pass an explicit configuration. Language layers have two common settings:

  • lsp: the LS to use. Defaults to nil, meaning visimp will install one from Mason for you if possible. If set to a string, a preinstalled executable with such name will be looked up on the system. If set to false, no LS is run;
  • lspconfig: if an LS is being used, the default LS-specific settings for it can be overwritten here.

Several language layers diverge from this basic configuration:

  • agda has its own doc page;
  • ampl does not have a LS on Mason, and thus can only be configured if a preinstalled executable is specified;
  • bash adds the fish option (defaults to false) which, if set to true, adds support for the Fish shell;
  • c adds the c and cpp options (both default to true) which enable support for both languages;
  • css adds the scss option (defaults to false) which, if set to true, adds Tree-sitter support for SCSS;
  • dart adds the flutter boolean option (defaults to false) and the flutterconfig table option for integration with the Flutter framework;
  • gleam has its own doc page;
  • hcl adds the terraform boolean option (defaults to true) to indicate whether to use or disable the Terraform LS;
  • idris has its own doc page;
  • javascript adds the typescript boolean option (defaults to true) to add Tree-sitter support for Typescript;
  • latex adds the autocompile (defaults to true) option for automatic compilation via LS and the tectonic (defaults to false) option to ask default LS Texlab to compile via Tectonic;
  • lean has its own doc page;
  • rocq has its own doc page;
  • toml does not have a LS on Mason, and thus can only be configured if a preinstalled executable is specified.

Examples#

-- path/of/your/vim/config/init.lua

require("visimp")({
  languages = {
   'go', -- we only list Go in the languages config as we like its defaults
   'latex',
  },
  latex = {
    -- Uses an externally managed LS rather than installing one from Mason
    lsp = 'texlab',
    -- LS-specific config https://github.com/latex-lsp/texlab/wiki/Configuration
    lspconfig = {
      texlab = {
        build = {
          executable = 'pdflatex',
        },
      },
    },
    -- Unlike lsp and lspconfig, this setting is specific to this language layer
    autocompile = false,
  },
})
