DEVirion is the virion dependency manager. It can be used to run plugins from source if they require virions.

Install this plugin
Create a directory called virions next to the plugins folder (not inside it!)
Drop the virions you use into the virions folder. Both packaged (.phar) virions and source (folder) virions are acceptable. (Just like how you install plugins with DevTools)

Notes

DEVirion will not shade plugins. Hence, this plugin must only be used for virion/plugin development. Released plugins must not depend on DEVirion to load virions.
DEVirion cannot automatically detect what virions are needed. Use the CLI to automatically download virions required for a certain project.

Command Line Options (for PocketMine)

You may also use the command-line option --load-virions to specify an additional folder to scan virions from (similar to the plugin path), or --load-virion (singular) to explicitly load a folder virion at the specified path (does not work with phar virions). For example, if you have this folder structure:

/ /server/ /server/PocketMine-MP.phar /server/start.sh /server/virions/ /server/virions/libweird.phar /server/virions/libstrange/ (with a virion.yml in this folder) /libs/ /libs/libodd.phar /libs/librare/ (with a virion.yml in this folder) /misc/ /misc/libnormal.phar /misc/libtrivial/ (with a virion.yml in this folder)

Running ./start.sh in /server/ will automatically load libweird and libstrange.
Running ./start.sh --load-virions=/libs/ will additionally load libodd and librare
Running ./start.sh --load-virion=/misc/libtrivial/ will additionally load libtrivial.
Running ./start.sh --load-virion=/misc/libnormal.phar will not load libnormal, because --load-virion does not support phar virions — it's usually not necessary, and you should copy it to virions folder instead.

Command Line Interface (Standalone executable)

Usage

=== DEVirion.phar usage === php /path/to/DEVirion.phar install [--replace]

Downloads all virions required by a project
is the path to the .poggit.yml of the project. You may put an URLs here.
is the case-insensitive name of the project.
is the path to the folder that virions should be installed in. This should be /path/to/your_server/virions
--replace will cause DEVirion to overwrite existing virions with the same name DEVirion uses ({VirionName}_v{MajorVersion}.phar)

php /path/to/DEVirion.phar download [--branch=":default"] [--output="/path/to/output.phar"]

Downloads a virion build from Poggit
, and are the case-insensitive names of the repo owner, repo and project containing the virion. can be ~ if same as .
is the SemVer version constraint for the virion required. Same as the version field in .poggit.yml
Only builds from the --branch branch will be used. ":default" means the current default branch of the repo. --branch or --branch=* will accept all branches.
If --output is provided, the virion will be downloaded to there. Otherwise, it is downloaded to .phar (or "_(n).phar" if exists). --output without a value will echo the file contents to stderr. (There is no option to echo to stdout because stdout is used for showing verbose information)

Requirements

To run the CLI,

PHP 7.0 or above is required
The OpenSSL extension must be present to provide the https:// wrapper (cURL is not required)
The YAML extension is required.
(Will be fixed soon) The production phar may not contain the shebang line #!/usr/bin/env php in the stub, so directly executing devirion.phar blah blah blah may not work.
