[Fish-users] Re: Proper behavior on very long prompt?
I dig around the code. And there was such comment before the judgement if to show “ /* Ignore prompts wider than the screen - only print a two character placeholder... It would be cool to truncate the prompt, but because it can contain escape sequences, this is harder than you'd think. */ I’d like an example how the “escape sequence” breaks the wrapping, and also I can check how bash/zsh handle it. I tried to remove the “ “ code and it seems working fine. I say, if the user has really crazy stuff to reach the right end of the prompt, he should take care of the crappy situation. I believe for most users, that’s not the case. (Or am I being naive?) At least, I’m thankful if (at least) there can be a variable to control it. no replacement to “ “ should be the default. -- BR, Tony Wang On June 17, 2013 at 15:18:23, ridiculous_fish (corydo...@ridiculousfish.com) wrote: Hi Tony, fish does not attempt to wrap or truncate long prompts. Prompts often contain ANSI escape sequences, which make them difficult to wrap or truncate. What you can do is inspect the value of $COLUMNS in your fish_prompt, and avoid outputting one that is too long. If you have any other ideas or suggestions for what fish should do here, I'd love to hear them.

What’s the consideration behind it? I don’t think it’s friendly to users. I tried to google, but found nothing. Is there any configuration to change that? Or, can I check if it happens, so I can try to show something abbreviated instead?

[Fish-users] “fg -”
Hi, In bash, I regularly use the “fg -” shortcut (it means switch to “previous job“, while “fg +” means “current job”). It is handy for alternating between two jobs. As far as I can see, fish's “fg” cannot do this, or am I missing something? If not, are there any plans to support this particular “bashism“ in fish?

Re: [Fish-users] “fg -”
Elias, I do this all the time under fish and have no problem. ^z to background a running task, `jobs` to see what is running, `fg` or `fg N` to bring something forward. It even works with the `command ` syntax to background a job at command time.

Re: [Fish-users] “fg -”
Synopsis: fg [PID] So if you have the PID of the process, you can use that directly. Otherwise you can use the job - process mapping operation, '%', to specify which job to put to the foreground. 2013/6/20 Robert Carpenter rob...@robacarp.com Ah, indeed, I think I read your initial post too quickly. In playing around with fg/bg just now, I've noticed that you have can't just specify a number: `fg 1`, but instead have to specify it like this: `fg %1` On Thu, Jun 20, 2013 at 11:05 AM, Elias Assmann elias.assm...@gmail.comwrote: On 06/20/2013 06:49 PM, Robert Carpenter wrote: I do this all the time under fish and have no problem. ^z to background a running task, `jobs` to see what is running, `fg` or `fg N` to bring something forward. It even works with the `command ` syntax to background a job at command time. “fg” and “fg %n” are very similar in both shells; “fg” means “bring the most recent job to the foreground”. Bash offers the additional syntax “fg -” which brings the next-most-recent job to the foreground. This is useful for alternating between two jobs. Let's say we start two terminal applications: $ octave octave:1 ^Z [1]+ Stopped octave $ emacs -nw ^Z [2]+ Stopped emacs -nw $ jobs [1]- Stopped octave [2]+ Stopped emacs -nw Note the “+” and “-”. Now, successive “fg -”s switch back and forth: $ fg - octave ^Z $ fg - emacs -nw By the way, bash's “fg” offers another nicety: it remembers which jobs were started in the background (i.e. with “”, rather than sent to the background later) and excludes them from “fg [-]”. In the example, say I open a document with “gv ”; if I then say “fg” it is unlikely that I want to bring “gv” to the foreground.
