pycharm optimize imports

Auto import—PyCharm

python argparse

Seems the best current default way to do cli options! Docs tutorial is as accessible as usual: Argparse Tutorial — Python 3.9.1 documentation

parser = argparse.ArgumentParser(formatter_class=argparse.ArgumentDefaultsHelpFormatter) # show default args in help
parser = argparse.ArgumentParser(formatter_class=argparse.RawTextHelpFormatter) # allow newlines in help text
parser.add_argument("-lp", "--localpath", help="Local path. \n %(default)s", default=local_path) # add default text in help text manually

Python shadowing modules

When creating argparse.py, don’t be surprised if you can’t use argparse from import argparse. ¹

Python to read, TODO

Nice article: PyFormat: Using % and .format() for great good!

ag as grep alternative for code

I should make an effort to learn it and use it. ag -G "component.*yaml" regex - searches for regex inside all files whose path matches the regex after -G

ag --python "myregex" automatically looks for it in all python files, and really nicely outputs matches!

vim delete lines not containing a pattern

g!/pattern/d, as opposed to the usual g without exclamation mark.

Using less to copy cli stuff with weird linebreaks

If command returns output with newline breaks that are ignored when copypasting directly, using command | less seems to make it work - I can copypaste from there without problems.
