Allow delimiters for output from Stdin about rich-cli HOT 6 CLOSED

Thanks @audunsol for your solution. I like to see the output of ps in colors, thanks to rich-cli. Thanks @willmcgugan for this work.

.

I want to test with other Linux commands.

Yes, I was looking for something similar to rich - --separator=whitespace

from rich-cli.

The above cool way to format ps output using rich did not work for me. That is because my process ids were not all the same length so the tr put some commas at the beginning of some lines which made the output not valid csv.

I modified the sed part to remove all leading and trailing whitespace from all lines. That seemed to work:

ps | sed 's/^[ \t]*//;s/[ \t]*$//' | tr -s '[:blank:]' ',' | rich - --csv

from rich-cli.

Why are you rendering the output of ps as markdown? What output are you expecting?

from rich-cli.

As a table (a rendering similar to that with --csv option). I also tried the following:

ps |rich - -m --csv

This gives the same output as above.

from rich-cli.

The output of ps isn't markdown, so I'm not surprised it wouldn't render. The output can't be markdown and CSV at the same time (the combination of those two switches should really be an error).

The output isn't a CSV either. So I'm afraid there is not much that rich-cli can do about that.

Just found this while looking for something similar, so just wanted to post a workaround to how to use rich-cli to nicely format ps output.

• first remove the spaces before PID column by something like sed 's/\s*PID/PID/i'
• then replace all blank space with , with trto make output CSV-like
• then pipe it to rich-cli with --csv option

ps \
  | sed 's/\s*PID/PID/i' \
  | tr -s '[:blank:]' ',' \
  | rich - --csv

Outputs:

┏━━━━━━━┳━━━━━━━━┳━━━━━━━━━━┳━━━━━━┓
┃   PID ┃ TTY    ┃ TIME     ┃ CMD  ┃
┡━━━━━━━╇━━━━━━━━╇━━━━━━━━━━╇━━━━━━┩

For completeness, since I just looked at the same thing for kubectl output:

kubectl get pods | tr -s '[:blank:]' ',' | rich - --csv

Outputs your pods with Rich CSV table formatting as:

┏━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┳━━━━━━━┳━━━━━━━━━┳━━━━━━━━━━┳━━━━━┓

It could of course be nice if rich-cli had an option to also accept white space separated output tables directly (like we get from a lot popular of command line tools, like docker, kubectl, ps, etc.), e.g.:

kubectl get pods | rich - --table

Or as I interpret the initial question/suggestion in this issue:

kubectl get pods | rich - --separator=whitespace

Anyways, thanks for a very nice CLI tool! 👍
