Racket-Cover.nvim

Shows code coverage for Racket and derived languages in Neovim

Dependencies

racket, obviously

Installation

Simply add gordoncyu/racket-cover.nvim to your favorite package manager. I use packer which looks like:

return packer.startup {
    function(use)
        use 'gordoncyu/racket-cover.nvim'
    end,
}

Then to load the plugin, call require('racket-cover').setup(). The function can take a table of options. The defaults are:

{
    highlight_uncovered = true, -- whether to highlight uncovered expressions or not
    uncovered_diagnostic = true, -- whether to generate diagnostics uncovered expressions or not
    coverage_dir = "/tmp/racket-cover", -- where to store coverage results
    highlight_group = { fg = "#ff0000", undercurl = true } -- how to highlight uncovered expressions
}

Usage

This plugin provides the following commands:

RacketCover: takes whitespace-separated filenames and runs their test modules, using the results to show uncovered expressions in-editor. Accepts % for the current file.
RacketCoverShow: shows uncovered expressions with highlights and/or diagnostics depending on configuration RacketCoverHide: hides uncovered expression highlights/diagnostics
RacketCoverToggle: toggles whether or not to show/hide uncovered expression highlights/diagnostics
