Re: EXWM: file or program not found, ls

[Gary Johnson]

Hi Olivier,

I'm also on GuixSD, using EXWM as my window manager. It sounds like you
have an issue with your PATH environment variable.

I set my environment variables in ~/.bash_profile, so that they are
automatically set on login and are therefore propagated to Emacs when it
is started by EXWM.

Here's an excerpt from my ~/.bash_profile to get you started:

#####################################################################
# Shell variables
export MYPROFILE=$HOME/.guix-profile
GUIX_PROFILE=$MYPROFILE source $MYPROFILE/etc/profile
export ASPELL_DICT_DIR=$MYPROFILE/lib/aspell
export GIT_EXEC_PATH=$MYPROFILE/libexec/git-core
export PATH=$MYPROFILE/bin:$MYPROFILE/sbin:$PATH
export CPATH=$MYPROFILE/include${CPATH:+:}$CPATH
export LIBRARY_PATH=$MYPROFILE/lib${LIBRARY_PATH:+:}$LIBRARY_PATH
export LD_LIBRARY_PATH=$MYPROFILE/lib${LD_LIBRARY_PATH:+:}$LD_LIBRARY_PATH
export 
PKG_CONFIG_PATH=$MYPROFILE/lib/pkgconfig:$MYPROFILE/share/pkgconfig${PKG_CONFIG_PATH:+:}$PKG_CONFIG_PATH
export

export ACLOCAL_PATH=$MYPROFILE/share/aclocal${ACLOCAL_PATH:+:}$ACLOCAL_PATH
export NODE_PATH=$MYPROFILE/lib/node_modules${NODE_PATH:+:}$NODE_PATH

# Remove duplicates from *PATH* variables
export PATH=`awk -F: '{for(i=1;i<=NF;i++){if(!($i in a)){a[$i];printf 
s$i;s=":"}}}'<<<$PATH`
export INFOPATH=`awk -F: '{for(i=1;i<=NF;i++){if(!($i in a)){a[$i];printf 
s$i;s=":"}}}'<<<$INFOPATH`
export CPATH=`awk -F: '{for(i=1;i<=NF;i++){if(!($i in a)){a[$i];printf 
s$i;s=":"}}}'<<<$CPATH`
export LIBRARY_PATH=`awk -F: '{for(i=1;i<=NF;i++){if(!($i in a)){a[$i];printf 
s$i;s=":"}}}'<<<$LIBRARY_PATH`
export LD_LIBRARY_PATH=`awk -F: '{for(i=1;i<=NF;i++){if(!($i in 
a)){a[$i];printf s$i;s=":"}}}'<<<$LD_LIBRARY_PATH`
export PKG_CONFIG_PATH=`awk -F: '{for(i=1;i<=NF;i++){if(!($i in 
a)){a[$i];printf s$i;s=":"}}}'<<<$PKG_CONFIG_PATH`
export GIO_EXTRA_MODULES=`awk -F: '{for(i=1;i<=NF;i++){if(!($i in 
a)){a[$i];printf s$i;s=":"}}}'<<<$GIO_EXTRA_MODULES`
export ACLOCAL_PATH=`awk -F: '{for(i=1;i<=NF;i++){if(!($i in a)){a[$i];printf

export NODE_PATH=`awk -F: '{for(i=1;i<=NF;i++){if(!($i in a)){a[$i];printf 
s$i;s=":"}}}'<<<$NODE_PATH`

I also make ~/.bashrc a symlink to ~/.bash_profile since these variable
definitions are idempotent. I don't do any other fancy magic with
~/.profile, ~/.xsession, or ~/.xinitrc other than using xsetroot, xset,
setxkbmap, xrdb, and friends to tweak my X setup in .xsession and then
call exwm on its final line.

Hope that helps!
