 with `:GoTest`. Run a single test with `:GoTestFunc`).
* Quickly execute your current file(s) with `:GoRun`.

* Debug programs with integrated `delve` support with `:GoDebugStart`.
* Completion and many other features support via `gopls`.

* Add or remove tags on struct fields with `:GoAddTags` and `:GoRemoveTags`.

## Install
vim-go requires at least Vim 8.2.5072 or Neovim 0.4.0.
The **latest stable release** is the
recommended version to use. If you choose to use the master branch instead,
please do so with caution; it is a _development_ branch.
vim-go follows the standard runtime path structure. Below are some helper lines
for popular package managers:
* Vim 8 packages
 * `git clone https://github.com/fatih/vim-go.git ~/.vim/pack/plugins/start/vim-go`
* Neovim packages
 * `git clone https://github.com/fatih/vim-go.git ~/.local/share/nvim/site/pack/plugins/start/vim-go`
* Pathogen
 * `git clone https://github.com/fatih/vim-go.git ~/.vim/bundle/vim-go`
* vim-plug
 * `Plug 'fatih/vim-go', { 'do': ':GoUpdateBinaries' }`
* Vundle
 * `Plugin 'fatih/vim-go'`
You will also need to install all the necessary binaries. vim-go makes it easy
to install all of them by providing a command, `:GoInstallBinaries`, which will
`go install` all the required binaries.
Check out the Install section in the documentation for more
detailed instructions (`:help go-install`).
## Usage
The full documentation can be found at doc/vim-go.txt. You can
display it from within Vim with `:help vim-go`.
Depending on your installation method, you may have to generate the plugin's
`help tags`
manually (e.g. `:helptags ALL`).
We also have a tutorial in the official vim-go wiki.
