fbenv
ATTENTION: Early alpha!
Why should I use this tool?
It is direnv but for a more global scope. So if you want to have directory based environments, use direnv
,
but if you want to have an environment for the current shell, you can use fbenv
.
Prerequisites
- Installation via
cargo install fbenv
- Optionally install fzf helping you with the zsh completion
Usage
- Add a file
fbenv.toml
to your home directory:
[environment1]
SOME_VAR = "foo"
[environment2]
SOME_VAR = "bar"
- Manual usage:
fbenv ls
to show the keys of all your environmentsfbenv get environment1
to get an output like:export FBENV=environment1; export SOME_VAR="foo";
- Switching to a given environment can be done manually:
- Evaluate the output of
fbenv
:eval $(fbenv get environment1)
printenv | grep SOME_VAR
should yield"foo"
- Evaluate the output of
- or via zsh completion
Known limitations
- Only TOML tables are currently supported as of now:
SOME_VAR = "blubb"
[environment1]
SOME_OTHER_VAR = "bla"
will ignore the variable SOME_VAR
!
ZSH completion
- Install
fzf
for adding extra sugar to your workflow :) - Add this to your
zsh
config:
if [[ -x "$(command -v fbenv)" ]];
then
if [[ -x "$(command -v fzf)" ]];
then
eval $(fbenv print-zsh-setup --with-fzf 2>/dev/null);
else
eval $(fbenv print-zsh-setup 2>/dev/null);
fi;
fi;
- Now you are able to switch environments via
switch-env
command
grml ZSH
When you are lucky to use the grml zsh config, you can add the current environment to your prompt:
function fb_env_prompt () {
if [ -n "$FBENV" ];
then
REPLY="fbenv ~ $FBENV "
else
REPLY=""
fi;
}
grml_theme_add_token longpath '%60<..<%~%<<' '%B' '%b
grml_theme_add_token magentahost '%m' '%F{magenta}' '%f'
grml_theme_add_token greenuser '%n' '%F{green}' '%f'
grml_theme_add_token gtprompt "»"
grml_theme_add_token space ' '
grml_theme_add_token fb-env -f fb_env_prompt '%F{cyan}' '%f'
zstyle ':prompt:grml:left:setup' items date space time fb-env change-root greenuser at magentahost newline gtprompt space
This will look like this:
