tree-sitter-validatetest

GStreamer ValidateTest grammar for tree-sitter.

This grammar parses .validatetest files used for testing GStreamer pipelines. These files are executed by gst-validate-1.0, ges-launch-1.0, or any GStreamer tool that supports the validate test format.

Features

• Full support for GstStructure serialization format
• Comments (# ...)
• Variables ($(variable_name))
• Expressions (expr(...))
• Type casts ((type)value)
• Property paths (element.pad::property)
• Arrays with nested structures ([...])
• GstValueArray (<...>)
• Value blocks ({...})

Installation

Neovim (with nvim-treesitter)

Add the following to your neovim configuration (e.g., lua/plugins/validatetest.lua for LazyVim):

-- Register the filetype
vim.filetype.add({
  extension = {
    validatetest = "validatetest",
  },
})

-- Register custom parser with nvim-treesitter
vim.api.nvim_create_autocmd("User", {
  pattern = "TSUpdate",
  callback = function()
    require("nvim-treesitter.parsers").validatetest = {
      install_info = {
        url = "https://github.com/thiblahute/tree-sitter-validatetest",
        files = { "src/parser.c" },
        branch = "main",
      },
    }
  end,
})

return {}

Then restart neovim and run :TSInstall validatetest.
