Setting up MMT
There are 2 ways to use MMT:
- download the binary distribution
- recommended for casual users
- self-contained except for needing the usual Java run time environment (Java 7 works fine, Java 8 has not been tested extensively, open-jdk has occasionally caused minor problems)
- clone the source distribution and build MMT yourself
- recommended for advanced users or developers
- additionally needs sbt (the Scala build tool) for building
Before installing MMT, you can optionally install jEdit. If jEdit is installed, MMT will automatically configure it to serve as an MMT IDE.
A list of releases can be found on the GitHub Releases page. The newest binary can be downloaded by clicking the top most item on the list.
To keep up-to-date, you can subscribe to the Atom Feed.
Clone the MMT repository from github:
git clone firstname.lastname@example.org:UniFormal/MMT.git
svn checkout https://github.com/UniFormal/MMT.git/trunk
A detailed explanation of the contents of the repository is available here.
If you do not have sbt, get it here.
Then build MMT using sbt (detailed instructions for building can be found here):
cd MMT/src sbt deploy
This should create many files, of course, in particular the file
mmt.jar in the folder
../deploy/. Change to that directory:
This assumes jEdit is installed and the MMT jar is obtained as described above. It is sometimes required to start jEdit once before running MMT setup as it creates some folders on first run that MMT installer uses.
To start setup run
java -jar mmt.jar.
This triggers the setup dialog which does the following:
- asks for directories into which MMT and MMT content should be placed.
- checks out some example content repositories into that directory (This requires git and internet access.),
- guesses the location of your jEdit settings directory and - if it exists - adds the MMT plugin to jEdit.
Further instructions for setting up jEdit are available here. In particular, the MMT plugin depends on some other standard plugins that you have to install.
To run MMT it is sufficient to run the jar file obtained as described above.
The canonical way for this is run
java -jar mmt.jar.
But depending on your OS and configuration, double-clicking or executing
mmt.jar may also work.
This responds with a simple setup dialog if MMT not installed, and drops to a shell otherwise.
If you have obtained MMT by building from sources make sure to go to the deploy folder first.
cd ../deploy java -jar mmt.jar
Additional instructions for running MMT are available here.
To update MMT, replace the file
- binary distribution: download the new file and save it over
- source distribution: update your working copy and rebuild.
To rerun setup, execute
java -jar mmt.jar :setup
However, rerunning setup is usually not necessary.
