Re: [Fish-users] $status in prompt
I've done 2 very small pull requests: https://github.com/fish-shell/fish-shell/pull/220 https://github.com/fish-shell/fish-shell/pull/221 I was about to add documentation for the echo builtin... but then I realized that it has already been written and it's there in my local checkout, so apparently even the online documentation is a bit outdated: http://ridiculousfish.com/shell/user_doc/html/index.html#echo I guess it still hasn't been setup to be automatically updated? (the first pull request is for the pwd command doc... not very useful, but at least now the builtins are complete) -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

So, given an abridged version of your example: codemonkey@monkeytree ~/W/grive function dummy nonexistant command echo $status end codemonkey@monkeytree ~/W/grive dummy fish: Unknown command “nonexistant” Standard input: nonexistant command ^ in function “dummy”, called on standard input, nonexistant: command not found 127 codemonkey@monkeytree ~/W/grive echo $status 0 codemonkey@monkeytree ~/W/grive The 'nonexistant' command sets the status to 127, which is displayed, but, since the echo executes after the error, echo itself returned zero, which then zero'ed out the status. In the discussion of setting your prompt, that's why you have to store the value. $status is volatile, and will change after every command. Just like $? in other shells. Hope this helps, -Dave Do you really think I could had written that example without understanding what you just explained? moreover: just try adding unexistantcommand at the bottom of your fish_prompt function: you'll see that it's more complicated than that (due to the fact that other shells usually compose their prompt with an env variable with is own syntax, while fish chose a more flexible -and simpler- approach) I don't want to get through as being hostile, but I'm getting quite frustrated by this back and forth... the issue is imho very simple: either this is recognized as a true inconsistency, and it's chosen to be dealt with by adding something to the documentation or you don't see this as truly inconsistent, and you think I should've thought out better my fish_prompt function in the first place either of these decisions are fine, let's just try to settle it with just few more words, okay? :) Peace :Dario -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

This is my prompt: Thank you, it works... but it seems a bit unintuitive that it has to be the first statement: I mean, fish_prompt is called each time, so having some other instructions inside would reset the $status, and then I don't see how it could still contain the correct value, after returning from fish_prompt whatever... now I don't have to worry about it anymore, thanks :) -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
