Any reason GUI mode is forced for man pages and the like?

[itamarst]

It'd be nice if eless could be set to always use console or alway use GUI, I found the seemingly random choice of one or the other confusing.

This has been fixed few minutes back (943a513).

Earlier the limitation was the emacs -Q -nw could not received input from the pipe. man always sends data to the end process like less ($PAGER) via a pipe. So the same limitation applied.

This has now been fixed. Please git pull again and let me know if it works.

could be set to always use console or alway use GUI,

Now by default, eless always opens in terminal mode. If you like to force GUI mode, pass the -gui switch.

With latest version for PAGER=eless man grep I am getting console emacs... but split into two panes.

[kaushalmodi]

As we cannot pass the -D flag for eless directly to man grep, set PAGER to eless -D.

• I do not see man started with split windows. What emacs version are you on? I am on the latest build of emacs.
• Here is the debug info I get:

24.5.1

I sorted of guessed that. The good news is that this issue has long been fixed. I would suggest that you upgrade to the recently released emacs 25.2.

I verified that the issue you mentioned happens on 24.5, but not on 25.1.

I'll still try fixing this so that it behaves the same for emacs 24.5 too.

[itamarst]

OK, thanks! I've been thinking about upgrading to latest Ubuntu, might be the excuse I need.

[kaushalmodi]

Let me know if this fixes the issue for you: 57668b7

Now it starts with two panes and then jumps into having only one after a moment. I should probably just upgrade to newer version of Emacs...

Thanks for the help, and for the neat tool!

Yeah, it's just a workaround.. I'll come back to this if I find a better way of fixing this.

Thanks for the help, and for the neat tool!

Glad to help!
