gitignore

I’m reading Pro Git and I learned that GitHub maintains a list of .gitignore templates. Those might come in handy.

My use case for git submodules

Posted on 2024-08-10 [Saturday] by Jay Jay

I have been chatting on IRC about how I’m learning git so I can use submodules and my friend @indigo wants to know my use case, so this post makes some effort to explain that with reference to one specific example.

I have a web framework/toolkit I am experimenting with called Mudball which is here: https://github.com/jj5/mudball

I use Mudball in (some of) my web projects, for example: https://github.com/jj5/www.jjlab.net

In the main project (in this case www.jjlab.net) I have a copy of Mudball in the ext/mudball directory. At the moment ext/mudball is setup as a git submodule.

I open the main project in my IDE (or text editor) and I want to be able to work on both the main application and the web framework/toolkit at the same time. Then when I’m done with some changes I want to run my `gui` script (it stands for “git update interactive”, not “graphical user interface”) which will increment my version numbers in inc/version.php and ext/mudball/inc/version.php and then add/commit/push any changes in both the main project and the web framework/toolkit.

The code for the `gui` command is here: kickass-libexec/bin/lx-gui.sh, it mostly just defers to lx_vcs_sync() which is here: kickass-libexec/src/2-module/vcs/vcs.sh.

The code which updates the version numbers is here: kickass-libexec/bin/lx-version-increment-patch.sh, it mostly just defers to other modules which are here: kickass-libexec/bin/libexec/version-increment-patch.php and here: kickass-libexec/bin/libexec/inc/version.php.

I have been using a similar setup for a long time with Subversion which uses the svn:externals facility (in place of git submodules) and I have a few scripts which help me manage that. My main tooling for this is known as svnman which is a bunch of scripts I wrote myself: Svnman.

This is the inaugural Mini Project! I introduced the Mini Projects recently. They are developed and published by Silicon Chip magazine, and sponsored by Jaycar Electronics (which is an Austrlaian electronics store, similar to Radio Shack in the USA, hopefully it doesn’t end up suffering the same fate.)

In this project, codenamed JMP001, we develop a USB keyboard which can send interesting and unusual symbols (which aren’t usually available on a keyboard) to a Windows computer using the alt-codes that it supports in a typical codepage.

For this first Mini Project I felt it was important to actually buy my components from Jaycar which I did for roughly eighty Australian dollary doos. Approximately US$50. The parts I ordered were these:

Belatedly I did also search for rubber feet.

There was quite a lot that went into the production of this video, and we accumulated a lot of links. Those are here:

In the end this first project was relatively successful, and we did get it to work fairly well on one of my Windows computers. As for the rest you can find out for youself in the video!
