`:GoJson` opens a temporary buffer where you can paste or write JSON.
197
+
Saving the buffer (`:w` or `:wq`) automatically closes it and inserts the generated Go struct into the original buffer at the cursor position.
198
+
199
+
Alternatively, you can pass JSON directly as an argument:
200
+
```vim
201
+
:GoJson {"name": "Alice", "age": 30}
202
+
```
203

204

Additionally, `gopher.json2go` provides lua api, see `:h gopher.nvim-json2go` for details.

287
+
## Troubleshooting
288
+
The most common issue with the plugin is missing dependencies.
289
+
Run `:checkhealth gopher` to verify that the plugin is installed correctly.
290
+
If any binaries are missing, install them using `:GoInstallDeps`.
291
+
292
+
If the issue persists, feel free to [open a new issue](https://github.com/olexsmir/gopher.nvim/issues/new).

`gopher.install_deps`
39
-
Gopher.nvim implements most of its features using third-party tools.
40
-
To install these tools, you can run `:GoInstallDeps` command
41
-
or call `require("gopher").install_deps()` if you want to use lua api.
42
-
By default dependencies will be installed asynchronously,
43
-
to install them synchronously pass `{sync = true}` as an argument.

113
-
`struct_tags` is utilizing the `gomodifytags` tool to add or remove tags to struct fields.
114
115
Usage ~
116
117
-
How to add/remove tags to struct fields:
118
1. Place cursor on the struct
119
2. Run `:GoTagAdd json` to add json tags to struct fields
120
3. Run `:GoTagRm json` to remove json tags to struct fields
121
122
-
To clear all tags from struct run: `:GoTagClear`
123
124
NOTE: if you dont specify the tag it will use `json` as default

145
*gopher.nvim-impl*
146
147
Integration of `impl` tool to generate method stubs for interfaces.
148
149
Usage ~
150
1. Automatically implement an interface for a struct:
151
-
- Place your cursor on the struct where you want to implement the interface.
152
-
- Run `:GoImpl io.Reader`
153
-
- This will automatically determine the receiver and implement the `io.Reader` interface.
154
155
2. Specify a custom receiver:
156
-
- Place your cursor on the struct
157
-
- Run `:GoImpl w io.Writer`, where:
158
-
- `w` is the receiver.
159
-
- `io.Writer` is the interface to implement.
160
161
3. Explicitly specify the receiver, struct, and interface:
162
-
- No need to place the cursor on the struct if all arguments are provided.
163
-
- Run `:GoImpl r RequestReader io.Reader`, where:
164
-
- `r` is the receiver.
165
-
- `RequestReader` is the struct.
166
-
- `io.Reader` is the interface to implement.
167
168
Example:
169
>go
···
184
Usage ~
185
186
- Generate unit test for specific function/method:
187
-
1. Place your cursor on the desired function/method.
188
-
2. Run `:GoTestAdd`
189
190
- Generate unit tests for *all* functions/methods in current file:
191
-
- run `:GoTestsAll`
192
193
- Generate unit tests *only* for *exported(public)* functions/methods:
194
-
- run `:GoTestsExp`
195
196
-
You can also specify the template to use for generating the tests. See |gopher.nvim-config|
197
-
More details about templates can be found at: https://github.com/cweill/gotests
198
199
If you prefer named tests, you can enable them in |gopher.nvim-config|.
200
···
217
This module provides a way to generate comments for Go code.
218
219
Usage ~
220
-
Set cursor on line with function/method/struct/etc and run `:GoCmt` to generate a comment.

*gopher.nvim-struct-tags*

139

`struct_tags` is utilizing the `gomodifytags` tool to add or remove tags to
140
+
struct fields.
141
142
Usage ~
143
144
+
How to add/remove/clear tags to struct fields:
145
1. Place cursor on the struct
146
2. Run `:GoTagAdd json` to add json tags to struct fields
147
3. Run `:GoTagRm json` to remove json tags to struct fields
148
+
4. Run `:GoTagClear` to clear all tags from struct fields
149
150
+
If you want to add/remove tag with options, you can use `json=omitempty`
151
+
(where json is tag, and omitempty is its option).
152
+
Example: `:GoTagAdd xml json=omitempty`
153
+
154

NOTE: if you dont specify the tag it will use `json` as default

178
+
Convert json to go type annotations.

184
+
generated Go struct into the original buffer at the cursor position.
185

258
- Generate unit tests for *all* functions/methods in current file:
259
+
- run `:GoTestsAll`
260
261
- Generate unit tests *only* for *exported(public)* functions/methods:
262
+
- run `:GoTestsExp`
263
264
+
You can also specify the template to use for generating the tests.
265
+
See |gopher.nvim-config|.
266
+
More details about templates: https://github.com/cweill/gotests
267
268
If you prefer named tests, you can enable them in |gopher.nvim-config|.
