Feature request: support setting --hyperlinks via the RICH_HYPERLINKS environment variable

[andelink]

Hi team, I've just discovered Rich and this CLI and I'm a big fan. Thanks for making this such an awesome tool!

While using it, I quickly noticed a desire to set-and-forget the --hyperlinks flag so I would not need to pass it every time. So making this an official request and have opened a PR for your review:

• Add support for setting --hyperlinks via the RICH_HYPERLINKS environment variable #61

This is the only change:

rich-cli/src/rich_cli/__main__.py

Line 378 in bc4da55

envvar="RICH_HYPERLINKS",

Hopefully you can take a look when you have a chance. Thanks!

Hey @willmcgugan, do you have any thoughts on this? PR:

• Add support for setting --hyperlinks via the RICH_HYPERLINKS environment variable #61

Seems reasonable. There are probably a few other env vars that could be added. Such as default theme.

I believe a default theme is already supported via RICH_THEME:

rich-cli/src/rich_cli/__main__.py

Lines 350 to 356 in 0721cb1

	@click.option(
	"--theme",
	metavar="THEME",
	help="Set syntax theme to [b]THEME[/b]. [dim]See https://pygments.org/styles/",
	default="ansi_dark",
	envvar="RICH_THEME",
	)

There are a few more listed in the rich docs:

Rich respects some standard environment variables.

Setting the environment variable TERM to "dumb" or "unknown" will disable color/style and some features that require moving the cursor, such as progress bars.

If the environment variable NO_COLOR is set, Rich will disable all color in the output.

If width/height arguments are not explicitly provided as arguments to Console then the environment variables COLUMNS/LINES can be used to set the console width/height. JUPYTER_COLUMNS/JUPYTER_LINES behave similarly and are used in Jupyter.
