Installing Cordova plugins

Before usage, Cordova plugins need to be installed in the GMA or GMI development environment.

Requirements for Cordova plugins installation

The following tools and utilities are required to install Cordova plugins:

Cordova plugins are available on a GitHub repository. Therefore, the git command line tool is required to install Cordova plugins.
The gmabuildtool uses the make utility to compile FGL wrappers and install Cordova plugins. Therefore, the make utility must be installed in the computer.

Cordova plugin installation basics

GitHub contains a large number of Cordova plugins that can be used in your app, like those from the Apache GitHub for example, or the FOURJS Cordova GitHub.

Before installing the Cordova plugins in the GMA / GMI installation directories, you must first clone the GitHub repository to your local disk.

Upgrading GMA, GMI or FGL with GMI with installed Cordova plugins

Cordova plugins need to be re-installed, after upgrading the GMA package (GMADIR), the GMI package (GMIDIR), or the FGL package if GMI is installed in FGLDIR.

The GMI package can be installed into the FGLDIR installation directory, or in a separate GMIDIR installation directory.
The GMA package is always installed in a GMADIR installation directory.

Important: In all cases, after upgrading an FGL, GMI or GMA environment where plugins have been installed, you need to re-execute the plugin installation with a gmabuildtool cordova --install-plugin or gmibuildtool --install-plugin command.

Installing a Cordova plugin from a local clone of the GitHub repository

First clone the GitHub repository into a local directory:

$ cd /usr/dev/myplugins
$ git clone https://github.com/apache/cordova-plugin-network-information.git

Then install the plugin:

For GMI / iOS:

$ gmibuildtool --install-plugins=/usr/dev/myplugins/cordova-plugin-network-information

For GMA / Android (note that you need to use the "scaffold" command):
```
$ gmabuildtool scaffold \
    --install-plugins /usr/dev/myplugins/cordova-plugin-network-information
```
Note: The gmabuildtool compiles cordova plugins FGL wrappers at installation with the make command. Compiled .42m modules will be bundled inside the scaffold archive. Before building an apk, FGL wrapper binaries will be copied inside the application directory.

Checking out a particular version from GitHub

If you want to test a particular version of a Cordova plugin, make a clone of the repository, and check out that version, then install the plugin:

$ cd cordova-plugin-network-information
$ git checkout specific-version
$ cd -

It is now possible to use the gmibuildtool or gmabuildtool to install this specific version.

Note: If a plugin with the same name is already installed, it is replaced by the new installation.

Checking Cordova plugin installation

Use the --list-plugins option of the GMA or GMI build tool, to check that the plugin is properly installed:

For GMI / iOS:

$ gmibuildtool --list-plugins
...
cordova-plugin-network-information
...

For GMA / Android (note that you need to use the "scaffold" command):

$ gmabuildtool scaffold --list-plugins
...
cordova-plugin-network-information
...

The cordova-plugin-network-information name can now be used for bundling an application using that plugin.

Finding Cordova plugin wrapper libs in development environment

After installing the Cordova plugin, if the plugin repository includes a BDL wrapper library, the fglrun runtime system needs to know where the .42m p-code modules can be found.

If there is a local clone of the GitHub repository, search for *.4gl files (typically prefixed with "fglcdv"), make sure they are compiled to .42m modules, and set the FGLLDPATH to the directory where the .42m files are located.

For example (on Unix/Linux), with the cordova-plugin-media repository clone:

$ cd cordova-plugin-media
$ find . -name "fglcdv*.4gl"
./fgl/fglcdvMedia.4gl
$ cd fgl
$ fglcomp fglcdvMedia.4gl      (or make, if makefile is present)
$ export FGLLDPATH=$PWD        (or export FGLLDPATH=$PWD:$FGLLDPATH)
