git clone --depth=1 https://github.com/stevearc/flow-coverage.nvim.git ~/.vim/bundle/

Neovim native package

  "${XDG_DATA_HOME:-$HOME/.local/share}"/nvim/site/pack/flow-coverage/start/flow-coverage.nvim

Setup

Step one is to get Neovim LSP set up, which is beyond the scope of this guide. See nvim-lspconfig for instructions. You will need to use that plugin to set up the flow LSP, for example:

require('lspconfig').flow.setup{}

When the flow LSP client is configured and this plugin is installed, Neovim will automatically start showing uncovered lines using standard diagnostics display. Additionally, you can get the coverage percentage with:

require('flow').get_coverage_percent()

Configuration

Variable	Type	Default	Description
g:flow_coverage_interval	number	5000	How often (in ms) to refresh the type coverage of a file. Set to 0 to disable.
