Programmatically disable colors in error messages

[thorn0]

When prettier is used programmatically and throws an exception, this exception contains color codes, On Windows, if it isn't caught, the exception outputs in such a way that the color codes make it to the screen, so it looks like this:

d:\dev\asdf\node_modules\prettier\index.js:23135
      throw error;
      ^

SyntaxError: Invalid character. (1:8)
←[0m←[31m←[1m>←[22m←[39m←[90m 1 | ←[39mlodash ←[33m#←[39m(x as number )←[0m
←[0m ←[90m   | ←[39m       ←[31m←[1m^←[22m←[39m←[0m
    at createError (d:\dev\asdf\node_modules\prettier\parser-typescript.js:1:194)
    at.parser [as parse] (d:\dev\asdf\simple.js:7:19)
    ...

I found that I can pass the --no-color command line argument to my program to turn off those codes, but I'd like to hard code it somehow, and I didn't find a good way to do it.

It even might make sense to disable colors by default and only enable them when prettier is used from CLI.

You might be able to set the environment variable FORCE_COLOR=0 before require():ing anything. See: https://github.com/chalk/supports-color#info. Pretty ugly solution, but it might get you unblocked for now :)

The worst part of these soluions is that they disable chalk globally for the whole program, not for prettier only.
