This is a plugin for rbenv that lets you set global and project-specific environment variables before spawning Ruby processes.
To install rbenv-vars, clone this repository into your
~/.rbenv/plugins directory. (You'll need a recent version of rbenv
that supports plugin bundles.)
$ mkdir -p ~/.rbenv/plugins $ cd ~/.rbenv/plugins $ git clone https://github.com/sstephenson/rbenv-vars.git
Define environment variables in an
.rbenv-vars file in your project,
one variable per line, in the format
VAR=value. For example:
RUBY_GC_MALLOC_LIMIT=50000000 RUBY_HEAP_MIN_SLOTS=15000 RUBY_FREE_MIN=4096
You can perform variable substitution with the traditional
syntax. For example, to append to
You may also have conditional variable assignments, such that a variable will only be set if it is not already defined or is blank:
JAVA_OPTS?=-server -Xmx768m -Xms768m -Xmn128m -Xss20m
In the above case,
JAVA_OPTS will only be set if
currently empty (i.e., if
[ -z "$JAVA_OPTS" ] is true).
Spaces are allowed in values; quoting is not necessary. Expansion and
command substitution are not allowed. Lines beginning with
# or any
lines not in the format VAR=value will be ignored.
Variables specified in the
~/.rbenv/vars file will be set
first. Then variables specified in
.rbenv-vars files in any parent
directories of the current directory will be set. Variables from the
.rbenv-vars file in the current directory are set last.
rbenv vars command to print all environment variables in the
order they'll be set.
