To obtain and set up MMT, perform the following steps:
Java 8 (both
OracleJDK are supported), and preliminary support for
Java 9 exists.
Java 11 works as well.
Java 7 is no longer officially supported.
jEdit is a Java-based text editor. MMT includes a jEdit plugin, which turns jEdit into an IDE for MMT. This step is optional but highly recommended if you want to write or view MMT files. If you just want to sample MMT, you should definitely do it with jEdit.
MMT uses git internally, so make sure it is installed.
There are two options for this step:
mmt.jar provides a self-contained executable file.
mmt.jar is released roughly every 2 months.
A list of releases can be found on the GitHub Releases page.
The latest one can be downloaded by clicking the top most item on the list.
Clone the MMT repository from GitHub:
git clone email@example.com:UniFormal/MMT.git
Alternatively, if you do not have ssh keys set up, use
git clone https://github.com/UniFormal/MMT.git`
A detailed explanation of the contents of the repository is available here.
MMT is currently built for
Scala 2.12.3 (incuded in the repository) and building is done with sbt (the Scala build tool).
If you do not have sbt, you can get it here.
To build, execute
cd MMT/src sbt mmt/deploy
(Detailed instructions for building can be found here).
This creates many files, in particular the file
mmt.jar in the folder
Change to that directory:
mmt.jar, this directory contains executable scripts (for Windows and Unix) to for running MMT.
In the previous, you obtained the file
mmt.jar (by downloading or building).
To start setup open a shell and run
java -jar mmt.jar.
On Windows, this assumes that
git can be called from within
sh, which means
sh has to be in your PATH; depending on how you installed
git, this may already be the case. If it is not in your PATH, you can also directly issue the
java -jar mmt.jar command from within Git Bash from an existing Git for Windows installation.
This triggers the setup dialog which does the following:
Further instructions for setting up jEdit are available here.
If you want to use MMT via jEdit, you do not have to run MMT itself.
It will act as a plugin within jEdit: just start jEdit and open
Developers or advanced users may want to run MMT directly for various other applications.
The canonical way for this is to run
java -jar mmt.jar.
(This responds with a simple setup dialog if MMT not installed, and drops to a shell otherwise.)
But depending on your OS and configuration, double-clicking or executing
mmt.jar may also work.
Additional instructions for running MMT are available here.
This step is not part of the initial setup. It is only needed later when updating your MMT installation to the latest release.
To update MMT, replace the file
To rerun setup, execute
java -jar mmt.jar :setup
However, rerunning setup is usually not necessary.
