Formatting doesn't work with watch

[david-jointech]

When using watch --color khal calendar the formatting (bold text and colors) doesn't seem to work.

I don't know exactly if this is an issue with khal or if it is one with watch. But watch does work for me with other programs (for example todotxt doesn't lose its color or boldness), so I am guessing khal is doing something differently here.

Using khal without watch (even with sh) works as expected. Does someone have an idea what the problem could be?

Okay, I figured it out. watch --color khal --color does the trick. Only the calendar-color doesn't get shown, which I guess has to do with that one not being part of the shells color-theme.

Still sounds like a bug then, I'll reopen the issue. Can you post the output?

[david-jointech]

Which output exactly? The one from watch --color khal?
If I read the help correctly it kinda works as intended: --color / --no-color Use colored/uncolored output. Default is to only enable colors when not part of a pipe.. I guess watch does count as a pipe and thus disables colors.

$ watch --color khal --color

Doesn't display any color for me, while khal alone (without watch) does colorize the output.
Both commands are able to display bold text.

$ khal --version
khal, version 0.9.9

$ watch --version
watch from procps-ng 3.3.15

This seems to be an issue with the watch command itself.
Other command line tools such as taskwarrior are also impacted equally.

Foreground colors not in the 16 colors palette are displayed in the default color.
Background colors aren't displayed at all.

khal should perhaps try to match the closest available color in this case.
