A simple package manager for Matlab (inspired by pip). Downloads packages from Matlab Central's File Exchange, GitHub repositories, or any other url pointing to a .zip file.
Download/clone this repo and add it to your Matlab path (using addpath). Now try the following:
mpi install [package-name]: install package by namempi uninstall [package-name]: remove package, if installedmpi search [package-name]: search for package given name (checks Github and Matlab File Exchange)mpi freeze: lists all packages currently installedmpi init: adds all installed packages to path (run when Matlab starts up)
By default, mpi installs all Matlab packages to the directory mpi-packages/. (You can edit mpi_config.m to specify a custom default installation directory.)
If you restart Matlab, you'll want to run mpi init to re-add all the folders in the installation directory to your Matlab path. Better yet, just run mpi init from your Matlab startup script.
Install (searches FileExchange and Github):
>> mpi install export_fig
When installing, mpi checks for a file in the package called install.m, which it will run after confirming (or add --force to auto-confirm). It also checks for a file called pathlist.m which tells it which paths (if any) to add.
Install a Github release (by tag, branch, or commit)
By tag:
>> mpi install matlab2tikz -t 1.0.0
By branch:
>> mpi install matlab2tikz -t develop
By commit:
>> mpi install matlab2tikz -t ca56d9f
Uninstall
>> mpi uninstall matlab2tikz
When uninstalling, mpi checks for a file in the package called uninstall.m, which it will run after confirming (or add --force to auto-confirm).
Search without installing:
>> mpi search export_fig
Install from a url:
>> mpi install covidx -u https://www.mathworks.com/matlabcentral/fileexchange/76213-covidx
OR:
>> mpi install export_fig -u https://github.com/altmany/export_fig.git
(Note that when specifying Github repo urls you must add the '.git' to the url.)
Install local package:
>> mpi install my_package -u path/to/package --local
The above will copy path/to/package into the default install directory. To skip the copy, add -e to the above command.
Overwrite existing packages:
>> mpi install matlab2tikz --force
Install/uninstall packages in a specific directory:
>> mpi install matlab2tikz -d /Users/mobeets/mypath
Note that the default installation directory is mpi-packages/.
mpi has rudimentary support for managing collections of packages. To specify which collection to act on, use -c [collection_name]. Default collection is "default".
>> mpi install cbrewer -c test
Using collection "test"
Collecting 'cbrewer'...

Downloading https://www.mathworks.com/matlabcentral/fileexchange/58350-cbrewer2?download=true...
>> mpi init -c test
Using collection "test"
Adding to path: /Users/mobeets/code/mpi/mpi-packages/mpi-collections/test/cbrewer
Added paths for 1 package(s).
>> mpi install -i /Users/mobeets/example/requirements.txt
Specifying a requirements file lets you install or search for multiple packages at once. See 'requirements-example.txt' for an example. Make sure to provide an absolute path to the file!
To automatically confirm installation without being prompted, set --approve. Note that this is only available when installing packages from file.
mpi was previously known as "mpm". (We had to change the name because Matlab started using "mpm" as a way of installing Matlab toolboxes.)
One way of transitioning from (our) mpm to mpi is to simply reinstall all packages/collections using mpi, which will use the new default installation path in mpi-packages/. Alternatively, point mpi to the folder containing any previously installed packages by changing mpi-packages to mpm-packages in mpi_config.m.
Because there's no standard directory structure for a Matlab package, automatically adding paths can get a bit messy. When mpi downloads a package, it adds a single folder within that package to your Matlab path. If there are no *.m files in the package's base directory, it looks in folders called 'bin', 'src', 'lib', or 'code' instead. You can specify the name of an internal directory by passing in an -n or internaldir argument. To install a package without modifying any paths, set --nopaths. Or to add all subfolders in a package to the path, set --allpaths.
mpi keeps track of the packages it's downloaded in a file called mpi.mat, within each installation directory.
If you are having trouble, please submit an issue.
mpi should work cross-platform on versions Matlab 2014b and later. Also note that, starting with Matlab 2022, you may see a warning when using mpi, as Matlab includes a built-in command of the same name (used for installing Matlab products). You may need to rename the file mpi.m to something else, and then rename the function name on line 1 of this file to match, as well as the line containing "help mpi".
