`: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.

+
## 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`

-
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.

+
How to add/remove/clear tags to struct fields:
118
145
1. Place cursor on the struct
119
146
2. Run `:GoTagAdd json` to add json tags to struct fields
120
147
3. Run `:GoTagRm json` to remove json tags to struct fields
148
+
4. Run `:GoTagClear` to clear all tags from struct fields
121
149
122
-
To clear all tags from struct run: `:GoTagClear`
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
+
123
154
124
155
NOTE: if you dont specify the tag it will use `json` as default

*gopher.nvim-impl*
146
213
147
214
Integration of `impl` tool to generate method stubs for interfaces.
148
215
149
216
Usage ~
217
+
150
218
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.
219
+
- Place your cursor on the struct where you want to implement the interface.
220
+
- Run `:GoImpl io.Reader`
221
+
- This will automatically determine the receiver and implement the `io.Reader` interface.
154
222
155
223
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.
224
+
- Place your cursor on the struct
225
+
- Run `:GoImpl w io.Writer`, where:
226
+
- `w` is the receiver.
227
+
- `io.Writer` is the interface to implement.
160
228
161
229
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.
230
+
- No need to place the cursor on the struct if all arguments are provided.
231
+
- Run `:GoImpl r RequestReader io.Reader`, where:
232
+
- `r` is the receiver.
233
+
- `RequestReader` is the struct.
234
+
- `io.Reader` is the interface to implement.

252
Usage ~
185
253

187
-
1. Place your cursor on the desired function/method.
188
-
2. Run `:GoTestAdd`
255
+
1. Place your cursor on the desired function/method.
256
+
2. Run `:GoTestAdd`
189
257
190
258
- Generate unit tests for *all* functions/methods in current file:
191
-
- run `:GoTestsAll`
259
+
- run `:GoTestsAll`
192
260
193
261
- Generate unit tests *only* for *exported(public)* functions/methods:
194
-
- run `:GoTestsExp`
262
+
- run `:GoTestsExp`
195
263
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
264
+
You can also specify the template to use for generating the tests.
