|
The addin name (passed through the `name` argument) is optional here. In
|
|
this case, the name will use the internal name...which can be guessed using
|
|
the binary name (e.i '/path/to/the/super_addin.elf' -> internal name =
|
|
'super_addin' -> output name = '/path/to/the/super_addin').
|
|
|
|
The output path for the generated file is, by defautl, the same path that
|
|
the binary but the suffix '.vxos' will be added.
|
|
|
|
if the icon is not specified, a default blank icon will be used.
|
|
|
|
Args:
|
|
> binary (str) - binary path
|
|
> icon (str) - addin icon path (optional)
|
|
> name (str) - addin name (displayed in the menu) (optional)
|
|
> output (str) - output path for the generated addin (optional)
