Hacking instructions don't work

[DamienCassou]

In http://nixos.org/nix/manual/#chap-hacking, the instructions to start working on the project don't work for me (I'm on NixOS unstable).

[projects/nix]$ echo $SHLVL

[projects/nix]$ ./dev-shell 

[projects/nix]$ echo $SHLVL

This works fine for me, against NixOS/nixpkgs@c5cbda2 (release-16.03) and NixOS/nixpkgs@ed0eb59 (master).

[DamienCassou]

@shlevy can it be related to nix-community/emacs2nix#23 ?

[shlevy]

No idea, sorry

[projects/nix]$ echo $SHLVL

Can you reproduce this without extra shell layer?

Also, your prompt text didn't change, but I have this

danbst@jolly ~/nix$ ./dev-shell

[nix-shell:~/nix]$ 

Maybe you have some magic in .bashrc?

[DamienCassou]

I removed by ~/.bashrc. The gnome-terminal seems to always start at level 2, no idea why. If I switch to a tty, I have a level of 1 but the problem persists. Also, the prompt doesn't change.

[shlevy]

@DamienCassou Do you have a bash_profile? Can you share your configuration.nix? I suspect this is some kind of weird interaction with your shell configuration but it's hard to tell what it might be

[DamienCassou]

@shlevy I don't have any ~/.bash_profile. My configuration.nix is at https://gist.github.com/anonymous/8ac0a1e8b4b1f538e2e911674db92b2f.

[shlevy]

@DamienCassou Can you paste the output printed when you run bash -x (ideally from a vty, just to reduce confounders)

[DamienCassou]

@shlevy what do you mean by vty? How can I copy/paste the output of bash -x from a tty? I tried redirections, but this didn't work. When done from gnome-terminal, the output contains many many things that are not printed from a tty.

[shlevy]

Can you try in screen/tmux with a suitable scrollback? Again otherwise in a tty.

[DamienCassou]

@shlevy I found something interesting. ./dev-shell starts to work (i.e., the prompt is changed to nix-shell:[...]) as soon as I turn program.bash.enableCompletion off. If I turn it back on, it fails again. I reproduced that many times.

Here is the output of bash -x from gnome-terminal with bash completion off and removed ~/.bashrc.

$ bash -x
+ '[' -n '' -o -n '' ']'
+ __ETC_BASHRC_SOURCED=1
+ '[' -z 1 ']'
+ '[' -n '\s-\v\$ ' ']'
+ shopt -s checkwinsize
+ set +h
+ '[' xterm-256color '!=' dumb -o -n '' ']'
+ PROMPT_COLOR='1;31m'
+ let 1000
+ PROMPT_COLOR='1;32m'
+ PS1='\n\[\033[1;32m\][\u@\h:\w]\$\[\033[0m\] '
+ test xterm-256color = xterm
+ alias 'l=ls -alh'
+ alias 'll=ls -l'
+ alias 'ls=ls --color=tty'
+ test -f /etc/bashrc.local

[shlevy]

Hmm, I have enableCompletion too. What packages have anything in $profile/etc/bash_completion.d and $profile/share/bash-completion/completions, where $profile=/run/current-system or ~/.nix-profile?

[hedning]

Sounds exactly like #976, I'm guessing nix-shell -A etc. doesn't work either if you have completion on? #1034 should probably fix it.

[DamienCassou]

@shlevy nothing in /run/current-system. In ~/.nix-profile: dconf, subversion, git, password-store, backintime-common, bash-completion.

@hedning how can I apply this patch on top of NixOS please?
