Change selected text case?

[tsilvs]

Is there a command or a shortcut to switch cases for each selection (single or multicursor)?

If not, which micro Lua API to use to make an extension with such feature?

I can also probably try using textfilter perl for that.

For a single instance, textfilter is very convenient.

For one-liners, I recommend Python 'py' command. At least for me, Python is needed often and commands are thus easy to remember. I rarely use perl outside one-liners, and now 'py' can do that in Python, too.

My plugin palettero has case change with Python, but you can easily add perl, too. Palettero uses

textfilter py -x x.title()       # Title Case # apt-get install pythonpy

And similar for lower(), upper(), translate to ASCII, urlencode...

I would also be curious if it's possible to apply textfilter for each multicursor instance. Currently, textfilter seems to only apply to first selected instance. Maybe this could be a feature for micro itself?

Seems like a reasonable change to make. Implemented in #3511.

textfilter tr [:lower:] [:upper:] and textfilter tr [:upper:] [:lower:] can be used in Bash.

And even you can use:

• python3 -c "import sys; sys.stdout.write(sys.stdin.read().capitalize())" to put only the first letter to uppercase
• python3 -c "import sys; sys.stdout.write(sys.stdin.read().title())" to put the first letter of each word to uppercase

Remember to escape (\") the quotes to use it in bindings.json
