Installing Stata packages from GitHub

NOTE: to make your repository installable, you need packagename.pkg and stata.toc files. The MarkDoc Package can automatically build these files for you, making your package ready to be installable from any platform. github package provide an option named force that allows you to force install repositories which are not installable. However, the package still gives more credit to installable packages when using the github search command. Therefore, by making your package installable, you will receive much more attention from Stata users on GitHub. Using MarkDoc Package you can write the Stata help files using Markdown and build the toc and pkg files effortlessly.

github is a Stata module for installing Stata packages from GitHub, including previous releases of a package. You can install the latest version of the github command by executing the following code:

net install github, from("https://haghish.github.io/github/")

Installing a package

To install a package, all you need is the GitHub username and the name of the repository. For example, to install MarkDoc package, it is enough to type:

github install haghish/markdoc

Not all packages are installable. Stata repositories must have toc and pkg files in order to be installable. You can check whether a package is installable or not using the check subcommand. The search subcommand automatically checks for this.

github check haghish/markdoc

Uninstalling a package

To install a package, use the uninstall subcommand, followed by the package name. For example:

github uninstall markdoc

to uninstall github package itself, type:

ado uninstall github

Searching for a Stata package

You can search GitHub for Stata package using a keyword. Read the help file for more information

github search weaver, in(all)

Package Versions

GitHub allows archiving unlimited number of package versions. The github command has an option for specifying the package version, allowing installing previous package versions. For example, for installing an older version of MarkDoc package, say 3.8.0. you can type:

github install haghish/MarkDoc , version("3.8.0")

But were can you see the package versions? GitHub has a release tab that lists all of the previous releases of the software (See for example the previous releases of MarkDoc). But the good news is that github has a subcommand for listing all of the previous releases in Stata results windows and allows you to install any of them (as well as their package dependencies for that particular version, if specified) with a single mouse click or programmatically. To do so, type:

github query username/repository

For example, to list MarkDoc's previous releases, type:

. github query haghish/markdoc

Package Dependencies

Some package rely on other packages. The github command allows you to install the package dependencies with the specified version. To do so:

create a file named dependency.do and include it in the repository
this file is not meant to be installed in the PLUS directory therefore it should not be mentioned in the pkg file (see below)
include the code for installing the package dependencies in this do file. If the packages are hosted on GitHub, use the github command for installing the package dependencies and specify the requiered version.
github command looks for dependency.do after installing the package and if it finds it in the repository, it executes it.

For example, MarkDoc package has a dependency.do file that can serve as an example how the dependency file should be created. Naturally, the dependenc.do file is only executable by github install command.

Example of pkg file

The repository should include a file with .pkg suffix and an identical name as the package name. The name of the file doesn't have to be identical to the repository name, but it is strongly adviced to name the repository identical to the package name. Below is an example file of the github.pkg that is used for installing the package on your system. Note that the files that are meant to be copied on your system begin with F (bottom of the file)
