This is an old video I found while tidying up my files today. I recorded this back in September 2023, around about a year ago. Figured I might as well publish it on Elliot’s Extras.

In this video I unbox my Yum Cha M6013 Capacitance Meter and my Yum Cha MESR-100 ESR Meter. Then I attach some banana plugs to one of my Yum Cha Probe Tweezers.

Today I was organising my media files and I found this old video. I recorded this back in August 2023 but I never released it. I think back then I didn’t have this second channel and I decided this video wasn’t good enough for the main channel, so it just kind of got forgotten. But I thought it was fun so I have published it here for the record.

In this video I do a time lapse of me cleaning my resistors. While the time lapse is playing I include a narration in which I discuss things I had been reading at the time. There are two links for the show notes, being these:

This is an old video I released on Elliot’s Extras back in September 2023. It didn’t get a write up on the blog at the time, so just doing that now. In this video, which was the first ever video for Elliot’s Extras, my second channel, I organise some of my diodes from AliExpress. This is a really long and really boring video, a perfect fit for the first Elliot’s Extras video. :)

My use case for git submodules

Posted on by
7

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.
