Make shell a little bit safer with:
- add-default-case
- check-extra-masked-returns
- check-set-e-suppressed
- quote-safe-variables
- check-unassigned-uppercase
Although there are some stylistic decisions for uniformity:
- avoid-nullary-conditions
- deprecated-which
- require-variable-braces
Editorconfig can only act based on file extension and path, not
attributes, it remains a mean only for multiple collaborators to use the
same configuration on their editor. When it is too restrictive, such as
not considering the file syntax, use a lint tool for the specific file
type instead of trusting editorconfig. Changes were made to increase
readability.
- Maim causes no errors and has region and window capabilities;
- Scrot region capture puts some weird borders when dragging the mouse;
- Spectacle allows editing but is too feature rich (complicated); and
- Xfce4-screenshooter does not allow selecting both region and window.
