Flex SDK Version Manager

FVM is a work in progress! It DOES NOT WORK RIGHT NOW. I'll remove this notice when we're good to go.

fvm is a ruby gem and executable for managing versions of the Adobe Open Source Flex SDK.

It has only been tested on Mac OSX 10.6.4 and is likely to not work on many other configurations. If you have any success stories, however, please let me know and I'll add them here.

The manager provides a command-line installation process for any available Flex SDK versions and the ability to symlink to the SDK's executables from /usr/local/bin (The same place Homebrew suggests). This allows programs like mxmlc, asdoc, and compc to be available from the command line easily. The manager uses the symlink approach to make it easy to switch the symlinks immediately between installed versions of the SDK if you need to.

First, install the fvm gem:

gem install fvm

Next, add the following to your bash initialization script (bashrc, bash_init, /etc/profile, whatever you prefer):

[[ -s $(fvm restart --chomp) ]] && source $(fvm restart --chomp)
# This loads FVM into a shell session.

Note: If you also have rvm installed, make sure these lines go AFTER the rvm initialization.

Restart your shell and you're good to go.

• As of v0.1.1, I've only included mxmlc, asdoc, and compc to the list of executables to link. I'll be adding more as fast as I can test them out, but if you want some programs before others, hit me up.

• I'm still trying to find a clean way to reset $FLEX_HOME after installing/using a new Flex SDK version. Currently, the environment variable cannot be set in the ruby process, so there is a helper script, fvm-restart that you'll need to run after either of those commands. Also, fvm-restart will be run for any new shells (if you followed the installation instructions) so you could just re-start Terminal.

fvm install installs a specific Flex SDK version.

fvm list lists installed Flex SDK versions.

fvm use can switch symlinks to a specific installed Flex SDK version.

fvm unlink removes any symlinks installed by fvm.

fvm which prints the currently-linked Flex SDK version.

fvm-restart re-sets the $FLEX_HOME environment variable.

• fvm langref to install (or build) the language reference for this flex version
