ansi cursor escape codes prevent finding source file for compiler errors

I am running platformio with the current (MELPA installed) platformio-mode.el. When compile errors are generated, the escape characters for cursor motion are causing problems with the error file,line matching in emacs. I can work around this in two ways so far:

Modifying system .bashrc to define

export PLATFORMIO_NO_ANSI=true 
export PLATFORMIO_FORCE_ANSI=false

resolves the issue.

Changing command in platformio-mode.el in the platformio--exec function to run/build on line 81 from (cmd (concat "platformio -f -c emacs " target))) to (cmd (concat "platformio -f --no-ansi -c emacs " target)))

I was tying to figure out how to add the --no-ansi flag to the platformio.ini file, but have had no luck with this yet.

I am running emacs 26.3 on Ubuntu20.04

Thank you for the nice package - Rick Sorensen

Hi Rick,

Glad you like the package!

I had the morning off today so I finally got to sit down and take a look at this.

I'm guessing from the reading I did that there is no value in trying to keep these escape codes and properly format everything?

If so, I did find a few pages of interest:

--no-ansi seems to be the cleanest way of dealing with this.

They also provide the PLATFORMIO_NO_ANSI env var.

To be honest I don't even have platformio installed right now. I'll get everything set up on my end and see how the output looks.
