Silence specific warnings about shellcheck

[koalaman]

This is a good suggestion. Numbering error messages to allow things like this is something I've been meaning to do for quite a while.

Added --exclude in fbd85e9

[ptman]

Great. Can you give an example of using it?

[koalaman]

shellcheck --exclude=SC2086,SC2035 file

There's no config file yet, but you can make it somewhat more persistent by adding an alias in .bashrc:

alias shellcheck='shellcheck --exclude=SC2086'

Ah, I see that I failed to use markdown properly when first filing this issue.

Using pylint it is possible to write the disabled checks in comments in the source, close to the location where it should take effect.

# pylint: disable-msg=C0103
a = 1  # pylint will not complain about the one character variable name

That would make this feature even more useful

I tried finding some docs on how this is scoped, but couldn't and I don't want to try it and see. Does pylint does this per line, per structure or per file?

[ptman]

I believe it is scoped by python's scope. A # pylint: -line at the start of a method affects that method. One at the start of a file affects that file.

But even whole-file scoped would help compared to having to use command aliases (or Makefiles).

I added #43 for this functionality.
