I've made a package available on github, which can be installed with


Is there a way to have a stable URL that always points to the latest release, so that I don't need to change the installation instructions with every version?

    $\begingroup$ I think if you want to make this work using Mathematica technology you need to provide a PacletSite.mz file and use a bit more of the (I think still undocumented) Paclet functionality. How to do that is answered here, although the question is not really a duplicate to this one. There might be possibilities to achieve this (latest release URL) with github functionality, but there might be better places to get answers to that... $\endgroup$ Commented Nov 7, 2019 at 16:43

    $\begingroup$ In addition to the resource function Kuba mentions, check out the updateMaTeX[] function here: github.com/szhorvat/MaTeX#installation IGraph/M has a more complicated version of the same: github.com/szhorvat/IGraphM/blob/master/IGInstaller.m The FEMAddOns installer was also based on a version of this code. $\endgroup$

Assuming all we want to use is GitHub, the best way does not exist but there are couple of alternatives used by folks around.

Regardless of the final installation method it is safe to say that it is beneficial to first have a .paclet file created (search around for PackPaclet) and, depending on the method, attached to a GitHub release.

TLDR I am using ResourceFunction["GitHubInstall"][ author_, name_ ]

1.1. install.m script

You can add an install.m script in your repository. User is supposed to call Import @ "url/to/install.m" and the installation procedure does whatever you want it to do.



  • flexible installation routine


  • ugly url to type by the user: https://raw.githubusercontent.com/`username`/`pacletName`/master/install.m, sure it can be copied but the fewer steps the better.

1.2 ResourceFunction installation script

Presented in Szabolcs' MaTeX where the installation script is a ResourceFunction:



  • flexible installation routine
  • simple call e.g. ResourceFunction["MyPacletInstall"]


  • The resource function needs to be verified by WRI before it is available

2. GitHub hosted PacletSite

You just build .paclet to your repository and update PacletSite.info.



  • once paclet site is added user can quickly check for updates etc.
  • all WRI built-in functions based deploy-release-install


  • Adds a lot of weight to your repository since binary .paclets need to be kept there. For this reason probably not the best for large or frequently updated projects.

3.1. A paclet installation manager

The idea is to install a 'paclet manager' once and it should handle standard Github released packages.


  • MPM`

    I created a simple installation manager MPM`: https://github.com/kubaPod/MPM

    Once you install it (using install.m :)) you can just call MPMInstall["szhorvat", "MaTeX"]. Check more examples in the GitHub wiki or this answer

        Import["https://raw.githubusercontent.com/kubapod/mpm/master/install.m"] (*only once*)
        Needs @ "MPM`"
        MPMInstall["kubapod", "devtools"]
  • PDInstallPaclet

    Alternatively take a look at b3m2a1's PDInstallPaclet


  • easy to use
  • full of utilities


  • you need to trust the source of the manager like MPM (otoh with plain text .m it is easy to inspect)
  • unless standards are expanded it only does paclet install and any fancy setup needs to be run separately

3.2. ResourceFunction["GitHubInstall"]

I pushed a reduced version of the MPMInstall to the function repository. It is straightforward to use:

ResourceFunction["GitHubInstall"]["szhorvat", "matex"]

see ResourceFunction["GitHubInstall", "DocumentationNotebook"] for more information.

Cons and Pros the same as with 3.1 + it is easier to use.

  • $\begingroup$ Thanks for the comprehensive answer -- I'm still digesting it. Could you make your MPMInstall available as a ResourceFunction? $\endgroup$

  • $\begingroup$ @ChrisK I could but currently it contains few experimental features, like installing to a custom directory. I do not know if that is ok for them. I also plan to expand it and a resource function format does not feel right for anything more that a block of code. I need to think about it. $\endgroup$

  • $\begingroup$ I currently distribute my Mathematica applications manually with all files in a zip-file. Users just download the program from a homepage (e.g. packagex.hepforge.org) and place it in $UserBaseDirectory. Will this method be deprecated or no longer possible? Would I have to use paclets now? $\endgroup$

You can have a look at the resource functions FEMAddOnsInstall or MaTexInstall that are both interfacing paclets hosted on GitHub. Both packages have code to automatically find the latest asset and install it.

This is what it looks like in practice:

(* PacletObject["FEMAddOns", "1.3.2", <> ] *)

That's it. No URLs, Paclet manger stuff or any other monkey business, nothing. You do not even need to visit a web page. Just open M- and install the paclet. It can not get easier than that.

Update Info: For the first use of a ResourceFunction you need to be log into your account. That is a possible disadvantage I have been made aware of. At the time of writing the answer I was not aware of this.

Have a look at the code provided in the resource functions. Note that you need to write and get the resource function approved only once (copy it form either one of the two mentioned pages). Since there are already two functions that do this, I think yours will be approved too. You can then update your github repo to your hearts content.

  • $\begingroup$ I did mention ResourceFunction for MaTeX :) To be clear, author needs to write and submit that function and in case of quick fixes any delay in approval can be stresfull. Anyway, your and Szabolcs' comments convinced me that this way deserves a separate section with pros and cons. $\endgroup$

    $\begingroup$ Thanks for the idea. It seems a bit redundant to have a separate ResourceFunction for every package though. Could we make a more generic GitHubInstall ResourceFunction that takes a github username and repo as arguments -- i.e. ResourceFunction["GitHubInstall"]["WolframResearch","FEMAddOns"]? $\endgroup$

    $\begingroup$ @ChrisK that's what my PDInstallPaclet does (I wrote it to interface with packagedata.net originally). On the other hand, I refuse to contribute anything to the function repository on principle because I think it's a distraction and wasted time that could have been better spent elsewhere :) $\endgroup$

    $\begingroup$ @ChrisK I just did it with a stripped version of the MPMInstall and called it GitHubInstall. There is no point in pasting package contents to FR. I highly recommend to use MPM or PDInstallPaclet. This was my first, and last, submission so I don't know how long will it take. I will let you know. $\endgroup$
