colorizing words in text-info

[Vittorio Cagnetta]

Hi Victor!

Congratulations for your great work.

I added a "yad mode" to my library EasyBashGUI (https://sites.google.com/site/easybashgui)

Beside EBG, I work on an other open source project, related to a karaoke player.
It is finished, but it misses a better karaoke window (now it uses xterm).

I'm working on yad to add such feature:
E.g.:

...

echo "...Singing the song..." | yad --back=grey --fontname="60" --wrap --justify=center --margins=10 --tail --width 800 --height 600 --center --undecorated --text-info --button=Close:1 --button=Fullscreen:9

return_value="${?}"

if [ ${return_value} -eq 1 ]; then

...

...

My problem is that I need to color some words with *two* colors (words sung, and words to sing), and reload phrase with color that "moves" from left to right.

Is it possible?

Thanks in advance

Try to do it adapting a stuff like this:

$ Bold=$(tput bold)

$ Red=$(tput setaf 1)

$ Rst=$(tput setaf 9)

$ Blue=$(tput setaf 4)

$ Reset=$(tput sgr0)

$ echo ${Bold}I can write${Red} RED$Rst or$Blue BLUE$Reset

If it doesn't work, research about Pango Markup Language.

I don't remember how to change colors using Pango, but I do remember how to change size:

yad --text "Using <big>big</big> chars"

Or how to change emphasys:

yad --text "Using <b>bold</b> chars"

Or Both:

yad --text "Using <big><b>bigbold</b></big> chars"

or:

yad --text "Using <big><big><big><big><big><big><b>bigbold</b></big></big></big></big></big></big> chars"

Abcs,

Julio

Hi Julio!


Thanks for the answer.


No. Those tips don't fix my problem.  :(


Those tips modify chars in "normal" dialog, but I need "--text-info" dialog (for its "--tail" option).

In --text-info dialog, chars in file (or in StdIn) remain unchanged: control chars used to colorize are interpreted literally, and this behaviour is for tput chars as well for pango tags.


So my question is: how to change chars visualisation in --text-info depending directly from input text to display/render ???

hi. sorry, but this is impossible right now. i'll plan to add some
subset of html or pango markup for implement rich text functionality to
text-info dialog in a future, but now only plain text can be shown
