Pmodules are a hierarchical module environment based on Environment Modules. For the time being they are still using the C implementation of the Environment Modules.

Future plans

Version 2 will be a re-implementation in Tcl using the modulecmd of Environment Modules.
Version 3 will be implementat as extension of Environment Modules.

Install a new Pmodules environment

All Pmodules and all required software is installed in a directory hierarchy in one unique root directory. If required or prefered dedicated directories can be defined for temporary files and/or downloaded files.

In the most cases a Pmodules environment will be installed on a network file-system, but local disk is of course also possible. Just make sure you have write access to to Pmodules root directory. The Pmodules root directory defaults to /opt/psi.

Installation

clone this repository and cd into it.
create the Pmodules root directory and make sure you have write access with the user you want to use to setup the new Pmodules environment. In the following steps we use $PMODULES_ROOT as symbols for the root directory.
Run
```
./build configure --prefix=$PMODULES_ROOT
```
to configure a new Pmodules environment. This command creates the configuration file $PMODULES_ROOT/config/modbuild.conf and some directories under $PMODULES_ROOT required in the next steps.
Run
```
./build compile --prefix=$PMODULES_ROOT
```
to compile and install the required tools.

Run

./build install --prefix=$PMODULES_ROOT

to install the Pmodules scripts.

If you don't want to use $PMODULES_ROOT/var/tmp/${USER} for temporary files you can override the default by using the option --tmpdir=TEMP_DIR in step 3.

If you don't want to use $PMODULES_ROOT/var/distfiles for downloaded files you can override the default by using the option --distfilesdir=DISTDIR in step 3.
