Add cli convert subcommand, from raw KLE to JSON (#6898)
* Add initial pass at KLE convert * Add cli log on convert * Move kle2xy, add absolute filepath arg support * Add overwrite flag, and context sensitive conversion * Update docs/cli.md * Fix converter.py typo * Add convert unit test * Rename to kle2qmk * Rename subcommand * Rename subcommand to kle2json * Change tests to cover rename * Rename in __init__.py * Update CLI docs with new subcommand name * Fix from suggestions in PR #6898 * Help with cases of case sensitivity * Update cli.md * Use angle brackets to indicate required option * Make the output text more accurate

|
||||
qmk json-keymap [-o OUTPUT] filename
|
||||
```
|
||||
|
||||
## `qmk kle2json`
|
||||
|
||||
This command allows you to convert from raw KLE data to QMK Configurator JSON. It accepts either an absolute file path, or a file name in the current directory. By default it will not overwrite `info.json` if it is already present. Use the `-f` or `--force` flag to overwrite.
|
||||
|
||||
**Usage**:
|
||||
|
||||
```
|
||||
qmk kle2json [-f] <filename>
|
||||
```
|
||||
|
||||
**Examples**:
|
||||
|
||||
```
|
||||
$ qmk kle2json kle.txt
|
||||
☒ File info.json already exists, use -f or --force to overwrite.
|
||||
```
|
||||
|
||||
```
|
||||
$ qmk kle2json -f kle.txt -f
|
||||
Ψ Wrote out to info.json
|
||||
```
|
||||
|
||||
## `qmk list-keyboards`
|
||||
|
||||
This command lists all the keyboards currently defined in `qmk_firmware`
