[Feature request] Allow multicolor progress bars

[ehmicky]

This would be great if the "complete" part of the progress bar could be of a different color than the "incomplete" part of it.

Using ANSI color escapes in the barCompleteChar or barIncompleteChar options does not currently work because the values for those options must currently be 1 character long. Using colors in those options make the progress bar shorter and jump left and right.

(Note that it is possible though to give a color to the whole bar as the shades_grey preset shows.)

use a custom formatter

[ehmicky]

@AndiDittrich What about improving the default formatter instead?

I believe all that is needed is to replace string.substr() by slice-ansi() in the following three lines: https://github.com/AndiDittrich/Node.CLI-Progress/blob/master/lib/formatter.js#L30-L34.

I can submit a PR if you want.

generally the dependencies should be reduced to zero in the near future - it's a big problem to audit each dependency...therefore i won't add any new libraries (it is not neccessary to achive your goal).

[ehmicky]

Alright, no worries!

[AndiDittrich]

whats about an option like "barGlue" ? that's the easiest way to add custom colors for each sub-bar

[ehmicky]

Sure that works. However I would not go for a PR for this anymore. Thanks for the help though!

[AndiDittrich]

the barGlue option has been added to the master branch (upcoming v3.6)

[ehmicky]

Thanks!
