@patrislav1 What do you think? make it behave more similar to other tools... a bit annoying the flag package don't support long options

[patrislav1]

you mean like python argparse? yes would be nice
isn't there a golang equivalent for it?

[patrislav1]

oh I see you already implemented it 😮
I mean it would even better to have short aliases for common stuff like -s, --charboxsize Character box size etc. but don't know how straightforward it is to implement

Yeap! im using https://github.com/rsc/getopt that support short/long but now i noticed that the standard library flag package do seem to allow --flag and --flag= and can probably workaround support short flag also. So maybe can skip using the getopt package. Will have a look.

Ideas for other short flags to support? maybe also if some flags should be renamed?
