|
|
|
|
## Install
|
|
|
|
Pre-dependency: [go](https://github.com/golang/go) (tested on 1.17 and 1.18)
|
|
|
|
```lua
|
|
use {
|
|
"olexsmir/gopher.nvim",
|
|
requires = { -- dependencies
|
|
"nvim-lua/plenary.nvim",
|
|
"nvim-treesitter/nvim-treesitter",
|
|
},
|
|
}
|
|
```
|
|
|
|
Also, run `TSInstall go` if `go` parser if isn't installed yet.

|
|
|
|
By `.setup` function you can configure the plugin.

|
|
|
Note:
|
|
|
|
- Installer does not install the tool in user set path
|
|
|
|
```lua
|
|
require("gopher").setup {
|
|
commands = {
|
|
go = "go",
|
|
gomodifytags = "gomodifytags",
|
|
gotests = "~/go/bin/gotests", -- also you can set custom command path
|
|
impl = "impl",
|
|
},
|
|
}
|
|
```
|
|
|
|
## Features
|
|
|
|
1. Installation requires this go tool:
|
|
|
|
```vim
|
|
:GoInstallDeps

|
|
- [impl](https://github.com/josharian/impl)
|
|
- [gotests](https://github.com/cweill/gotests)
|
|
|
|
2. Modify struct tags:
|
|
By default `json` tag will be added/removed, if not set:
|
|
|
|
```vim
|
|
:GoTagAdd json " For add json tag
|
|

|
|
```

```
|
|
|
|
5. Interface implementation
|
|
|
|
Command syntax:
|
|
|
|
```vim
|
|
:GoImpl [receiver] [interface]
|
|
|
|
" Also you can put cursor on the struct and run:
|
|
:GoImpl [interface]
|
|
```
|
|
|
|
Example of usage:
|
|
|
|
```vim
|
|
" Example
|
|
:GoImpl r Read io.Reader
|
|
" or simply put your cursor in the struct and run:
|
|
:GoImpl io.Reader
|
|
```
|
|
|
|
6. Generate tests with [gotests](https://github.com/cweill/gotests)
|
|
|
|
Generate one test for spesific function/method:
|
|
|
|
```vim
|
|
:GoTestAdd
|
|
```
|
|
|
|
Generate all tests for all functions/methods in current file:
|
|
|
|
```vim
|
|
:GoTestsAll
|
|
```
|
|
|
|
Generate tests only for exported functions/methods in current file:
|
|
|
|
```vim
|
|
:GoTestsExp
|
|
```
|
|
|

```vim
|
|
" Run `go generate` in cwd path
|

|
|
:GoGenerate %
|
|
```
