BLT Launcher

A small wrapper around BLT for your global $PATH.

Why?

BLT must be installed on a per-project basis via Composer (composer require acquia/blt). This makes BLT available to your project by placing it at vendor/bin/blt.

However, it is inconvenient to type vendor/bin/blt in order to execute BLT commands. By installing the BLT launcher globally on your local machine, you can simply type blt on the command line, and the launcher will find and execute the project specific version of BLT located in your project's vendor directory.

Installation - Phar

1. Download latest stable release via CLI (code below) or browse to https://github.com/acquia/blt-launcher/releases/latest.

   OSX:

   curl -OL https://github.com/acquia/blt-launcher/releases/latest/download/blt.phar

   Linux:

   wget -O blt.phar https://github.com/acquia/blt-launcher/releases/latest/download/blt.phar

2. Make downloaded file executable: chmod +x blt.phar

3. Move blt.phar to a location listed in your $PATH, rename to blt:

   sudo mv blt.phar /usr/local/bin/blt

4. Windows users: create a blt.bat file in the same folder as blt.phar with the following lines. This gets around the problem where Windows does not know that .phar files are associated with php:

   @echo off
   php "%~dp0\blt.phar" %*

Update

The BLT Launcher Phar is able to self update to the latest release.

Alternatives

If you only have one codebase on your system (typical with VMs, Docker, etc,), you should add /path/to/vendor/bin to your $PATH. BLT is smart enough to find the PROJECT_ROOT and DRUPAL_ROOT when it is run from the bin directory.

Xdebug compatibility

BLT Launcher, like Composer automatically disables Xdebug by default. This improves performance substantially. You may override this feature by setting an environment variable. BLT_ALLOW_XDEBUG=1 blt [command]
