"--pure" won't work

In exploring Culturia, here

https://github.com/amirouche/Culturia/

I reach this line


guix environment --ad-hoc --pure guile-next


what happens is this (I'm not on Fedora anymore but rather on Ubuntu 16.04)


Command 'lesspipe' is available in the following places
 * /bin/lesspipe
 * /usr/bin/lesspipe
The command could not be located because '/usr/bin:/bin' is not included in
the PATH environment variable.
lesspipe: command not found
Command 'dircolors' is available in '/usr/bin/dircolors'
The command could not be located because '/usr/bin' is not included in the
PATH environment variable.
dircolors: command not found
Command 'ls' is available in '/bin/ls'
The command could not be located because '/bin' is not included in the PATH
environment variable.
ls: command not found



Without the "--pure" it works like a charm

Is this normal ? Or is there anything wrong ?

Am I supposed to put ls, dircolors and lesspipe in the --ad-hoc clause ?

I ask this because in order to have Geiser with all its features in
Culturia, gesier-next is needed (because guile-next is used)

But because the plain vanilla geiser is installed in my profile, I guess I
can't have guile-next in an environment and guile in the profile, unless
the environment is pure

Am I right here ?

Guix isn't doing any of this, your shell is.  Check your .bashrc or
the equivalent file for whatever shell you use.

Both with and without --pure works on my side. I don't remember why I've
put --pure in the README.

I use ubuntu 16.04.1, I have this in my ~/.zshrc

export PATH="/home/amirouche/.guix-profile/bin":$PATH
export GUIX_LOCPATH=~/.guix-profile/lib/locale
export 
GUILE_LOAD_PATH="/home/amirouche/.guix-profile/share/guile/site/2.2${GUILE_LOAD_PATH:+:}$GUILE_LOAD_PATH"
export 
GUILE_LOAD_COMPILED_PATH="/home/amirouche/.guix-profile/share/guile/site/2.2${GUILE_LOAD_COMPILED_PATH:+:}$GUILE_LOAD_COMPILED_PATH"
export 
INFOPATH="/home/amirouche/.guix-profile/share/info${INFOPATH:+:}$INFOPATH"

Thanks to the both of you

David's answer was a bit terse althought straight to the point

Just to widen the discussion a bit, yes, in order to have basic commands in
a "pure" environment, even ls, they need to be explicitly included (either
with the --ad-hoc clause or because they're dependencies of some of the
packages you're creating the env for)

In fact

guix environment --pure --ad-hoc guile-next --search-paths

will show the "bin" that'll be included in the environment path. Just ls
that bin folder and you'll find nothing more than the guile-next
dependencies. No ls, no lesspipe, no dircolors

On this, David's was assuming that I had read the manual already ;-)

Now, as for the reason why ls, lesspipe and dircolors get called, David is
right: the default .bashrc is full of stuff, it's a page long.

So those "errors" are harmless. The resulting environment will be perfectly
functional for Culturia to be explored ;-)

Thanks again !

This command drops you in a shell where only Guile is in $PATH—no
Coreutils, sed, grep, etc.  Maybe this isn’t intended?

Exactly, Ludo. No Coreutils, sed, grep, not even ls

I don't know wether this was intended or not. I was following the
instructions

AND I had misunderstood the effect of "--pure" myself.

It's all right now. I understood better, Amirouche declared that he doesn't
remember why he chose "--pure" and he didn't run into this because he uses
zsh, not bash (so the ubuntu .bashrc didn't affect him)

Thank you very much for chiming in !
