Setting enviroment variables

fummie · 5 March 2021 09:48

So I got environment variables listed in my ~/.config/fish/config.fish

set -x JAVA_HOME $HOME/.jdk-15.0.2
set -x PATH $PATH $JAVA_HOME/bin

set -x NODEJS_HOME $HOME/.node-v14.15.4
set -x PATH $PATH $NODEJS_HOME/bin

set -x PATH $PATH $HOME/.yarn-v1.22.5/bin

set -x GOPATH $HOME/.go1.16
set -x PATH $PATH $HOME/.go1.16/bin

And on printenv they are displayed correctly

But when i’m trying to use node or java from console,

$ ~> node --version
v15.10.0
$ ~> java --version
openjdk 15.0.2 2021-01-19
OpenJDK Runtime Environment (build 15.0.2+7)
OpenJDK 64-Bit Server VM (build 15.0.2+7, mixed mode)

it is using kits installed by pamac as dependencies required by other programs.

I guess it will be kinda newbie question, but can I use specific kits which I manually installed from my terminal, and let programs use whatever dependencies was installed by pamac? Would appreciate any help.

P. S. Same thing is happening, when I’m using bash. My system info:

I don’t know much about fish to help, but i guess setting variables in ~/.config/fish/config.fish only applies to commands executed through fish.

Depending on what you are trying to achieve, you may need to define your variables elsewhere.
https://wiki.archlinux.org/index.php/Environment_variables

Mirdarthos · 5 March 2021 12:00

I suspect that’s why they’re called environment values. they are for the environment. The name kinds gives it away.

I think what you’re looking for is Global Environment Variables. See the Arch wiki page regarding global environment variables.

Edit:

I’m guessing you can also create a startup script to do it and start the script at bootup eith systemd, but that’s just a guess.

Edit 3:

From this page, I’m thinking those environment variables of yours should be defined in/etc/environment:

/etc/environment

This file is system wide file for creating, editing or removing any environment variables. Environment variables created in this file are accessible all throughout the system, by each and every user, both locally and remotely.

So you could define it in /etc/environment. But be careful, because it’ll be available to any user system-wide.

I suspect a better idea would be to define them in ~/.profile file:

.bash_profile

This file is user specific remote login file. Environment variables listed in this file are invoked every time the user is logged in remotely i.e. using ssh session. If this file is not present, system looks for either .bash_login or .profile files.

fummie · 5 March 2021 14:21

Sorry, I didn’t express myself clearly. By that I ment that I already defined them in ~/.bash_profile

#
# ~/.bash_profile
#

[[ -f ~/.bashrc ]] && . ~/.bashrc

export JAVA_HOME=$HOME/.jdk-15.0.2
export PATH=$PATH:$JAVA_HOME/bin

export NODEJS_HOME=$HOME/.node-v14.15.4
export PATH=$PATH:$NODEJS_HOME/bin

export PATH=$PATH:$HOME/.yarn-v1.22.5/bin

export GOPATH=$HOME/.go1.16
export PATH=$PATH:$HOME/.go1.16/bin

And in bash it acts similarly

OpenJDK Runtime Environment (build 15.0.2+7)
OpenJDK 64-Bit Server VM (build 15.0.2+7, mixed mode)

Now I tried both /etc/environment and etc/profile and nothing changed.
Note that that behavior fair only for node and java, yarn and go work as expected

fummie@fummie-laptop ~> yarn --version
1.22.5
fummie@fummie-laptop ~> go version
go version go1.16 linux/amd64

So my best guess, that node 15.10.0-1 and jre-openjdk 15.0.2.u7-1 installed by pamac somehow override node and java varuables of .node-v14.15.4 and .jdk-15.0.2, which I placed in my home folder and defined in ~/.bash_config and ~/.config/fish/config.fish manually. If it’s true, I don’t know how to prevent this or if it even possible.

openminded · 5 March 2021 14:27

None of the above is correct. Use global variables as follows: set -gx %key% %value%. So in fact, you did right initially, just use -gx instead of -x.

Btw never mess with /etc/environment. It’s kinda using a hydraulic press in order to knock a nail.
Oh yeah, and consider reading fishshell.com/doc

As for bash, it’s not the same or similar as you said, it’s just different. For bash you need to set things in .bashrc / .bash_profile - it will ignore your “settings” unless you set variables there.

PS: I’ve changed the title. Hope you don’t mind.

Mirdarthos · 5 March 2021 14:38

Well, it teaches you proper aim and self-control to get it done. And it works

fummie · 5 March 2021 19:23

I have set all variables in as you suggested, so here my ~/.config/config.fish:

set -gx JAVA_HOME $HOME/.jdk-15.0.2
set -gx PATH $PATH $JAVA_HOME/bin

set -gx NODEJS_HOME $HOME/.node-v14.15.4
set -gx PATH $PATH $NODEJS_HOME/bin

set -gx PATH $PATH $HOME/.yarn-v1.22.5/bin

set -gx GOPATH $HOME/.go1.16
set -gx PATH $PATH $HOME/.go1.16/bin

But it still using node and jdk installed from pamac instead of defined above

stargazer · 5 March 2021 20:44

Maybe the arch script archlinux-java will help.

fummie · 5 March 2021 21:49

Nope. It only sees jdk installed by pamac

$ ~> archlinux-java status
Available Java environments:
  java-15-openjdk (default)

openminded · 7 March 2021 16:04

I believe I know what might be the cause of that weird problem. Pls look through your ~/.config/fish/fish_variables. There must be a single section with paths like this:

SETUVAR fish_user_paths:/home/openm/\x2elocal/bin\x3a/usr/local/sbin\x3a/usr/local/bin\x3a/usr/bin\x3a/opt/cuda/bin\x3a/usr/lib/jvm/default/bin\x3a/usr/bin/site_perl\x3a/usr/bin/vendor_perl\x3a/usr/bin/core_perl\x3a/home/openm/\x2ecargo/bin

\x2e means “.” (a dot), \x3a means “:”. Try editing that string the way you need it to be and make sure there’s no other strings beginning with SETUVAR fish_user_paths.
And comment/remove the relevant content of config.fish as well so only fish_variables will be responsible for settings $PATH.

fummie · 8 March 2021 10:31

I entered printenv, found my PATH variable:

PATH=/home/fummie/.local/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/opt/cuda/bin:/opt/cuda/integration/nsight-compute:/opt/cuda/integration/nsight-systems:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:/home/fummie/.jdk-15.0.2/bin:/home/fummie/.node-v14.15.4/bin:/home/fummie/.yarn-v1.22.5/bin:/home/fummie/.go1.16/bin

Copy/pasted that to ~/.config/fish/fish_variables (there was no SETUVAR fish_user_paths so I created one), changed every “.” to “\x2e” and “:” to “\x3a”, like you said, and deleted ~/.config/fish/config.fish. Now my ~/.config/fish/fish_variables looks like this:
