Haxe Version Manager (HVM)

A version manager for Haxe that lets you switch between multiple Haxe versions easily.

Works by compiling sources from the Haxelib git repo, and keeping a copy of the various compiled versions on hand, and then copying these to your system folders when they are needed.

Only tested on Ubuntu,

Installation

If you already have Haxe installed:

haxelib install hvm

In future we plan to support a bootstrapped version that can run without Haxe installed.

Usage

jason@jason-laptop:~$ haxelib run hvm
The Haxe Version Manager 0.0.1

  --use <version>          Install a version and set it as current.
  --install <version>      Install a version (if it isn't already). This 
                           fetches any updates in the repo, compiles it, and stores it 
                           in the repo. 
  --set <version>          Set an already installed version as current. 
                           Basically this copies a precompiled binary and standard 
                           library to the right location for them to be on the system. 
  --remove <version>       Remove an installed version. Please note this 
                           removes it from the HVM repo, it does not affect the 
                           currently installed version on the system. 
  --reinstall <version>    Remove a version, reinstall, set as current. Same 
                           as calling remove, install, set. 
  --list                   List versions that have already been installed and 
                           are available to be set. 

For version, you can use any git reference - a branch, a tag, a commit hash, etc. For example:

haxelib run hvm --use 3.1.3 # Use 3.1.3
haxelib run hvm --use development # Use the latest development version

Implementation Details

• This works by downloading the Haxe repo from GIT, checking out the appropriate tag/branch/commit, and compiling it.
• We store the compiled files for each version in a repo.
• When --set is used, the compiled version and the standard library are copied to your system path. You may need to use sudo for this to work.
• On Linux & Mac: You will need the build dependencies installed already. See http://haxe.org/documentation/introduction/building-haxe.html This assumes you have your Haxe binary at /usr/lib/haxe/haxe and the standard library at /usr/lib/haxe/std/. It would be nice to make this configurable. * This will place your repo in ~/.hvm/, where ~ is your home directory, found using the HOME environment variable.
• On Windows: * We are lacking an implementation, but it should be dead easy. See https://github.com/jasononeil/hvm/blob/master/src/hvm/platform/WinConfig.hx. Pull requests welcome.
