How to run filtertext to italicize text?

[bound-variable]

I can run echo -e "\e[3mSample Text\e23m" to output "Sample Text" in italics. How can I run micro's filtertext command with some selected text to accomplish this?

textfilter perl -0pe 's/(.*)/\x1b[3m$1\x1b[23m/gms' seems to work.

Explanation because Perl is a write-only language:

• perl -e executes a one line script
• -p makes it print the result
• -0 makes it work with multiline selections
• s/A/B/gms is a global multiline regex that replaces A with B

Micro will likely not render the control characters correctly though, so you will need to for example save the file and cat it to see the effect.

Thanks,

But didn't work for me. I got: x1b[3mSample Textx1b[23mx1b[3mx1b[23m. And cat just displayed those characters literally.

Oops, apparently I lost the quotes around the script somewhere along the way. With the quotes it should work (https://asciinema.org/a/7Ckq0jL9mrKw1f9HFki0n6MyV):

textfilter perl -0pe 's/(.*)/\x1b[3m$1\x1b[23m/gms'

It works! But, like you said, micro can't display them :(

I tried running textfilter into this bash script, but it just repaced the selected text with nothing:

while IFS= read -r text
do printf "\e[3m%s\e[23m" "$text"
done
