how to colorize files in edit mode depending on the file extension #10

Open chuck-haatvedt opened 2 years ago

after years of using ISPF on the mainframe and then using SPF/SE on windows, I'm looking for a way to colorize COBOL files in the xe or gxe edit session.

is that possible with the Hybrid XE editor ?

if so, any information on how to do it would be greatly appreciated.

   Thanks,

Chuck Haatvedt

I use xe with highlight installed. Highlight is a syntax highlighter that provides a nice way to do different colors to the syntax. there is documentation in XE on how to install highlight. highlight should support COBOL. A little round about way but much easier way to achieve what you need. highlight is available for linux and should be available for other OS as well

I have highlight installed and working on Lubuntu 22.10 however I have a couple of questions.

is it possible to set the background color in the attribute list ?

for example for strings I would like to have them foreground black and background yellow..

another possible option I could use would be a reverse-video attribute.

on another note. is it possible to use --output-format xterm256 with gxe or xe ?

and if so are there different themes that need to be used for that ?

Glad you have highlight working. i have limited success on using color options on the highlight command at xesynl.cfg. what works for me is: SHCMDA= "/usr/bin/highlight -q --out-format=ansi"

I am on debian and ubuntu install but all behave the same. My best bet has been to use 0 option in ISPF and play with colors, using the color palette. It then changes color on the highlighted syntax too.

xe only supports ansi format. The ansi format is supported by both Andre Simon's highlight and GNU's source-highlight. xe expected 0x1b[bg;fgm (bg:background color:41-->47, fg:forground color:31-->37) for the revers display, but 0x1b[07;fgm (07: is reverse attribute) was not expected. The next version will support this, but As a workaround, a method of replacing fg with bg by intermediate shell script is also conceivable. "s/[04;3([0-9])m/[30;4\1m/g" #1b[04;3xm--> 1b[4xm aviding to replace 1b[04;3x;4ym

I haven't confirmed the output of the reverse code in both highlighters. Since the output of Underline 0x1b[04m; has been confirmed, we will also add an option to reverse underline. In other words, when specified in xesynl.cfg and xesynw.cfg, the underline specification is treated as reverse. G_UNDERLINE=R #for wxe and gxe C_UNDERLINE=R #for cmdline xe
