I’m currently rebuilding my main Windows machine after it had become close to unusable. Given that I upgraded it multiple times from Windows 7 all the way to Windows 11 without ever reinstalling the OS, this shouldn’t have come as a major surprise. Either way, this is the reason for the sudden outburst of Windows related posts so I can go and refer to my blog as my Internet Notes repository.

I’ve blogged about improving the performance of Git on Windows in the past and rightly labelled the suggested solution as a bad hack because it requires you to manually replace binaries that are part of the installation. For people who tend to use DVCSs from the command line, manually replacing binaries is unlikely to be a big deal but it’s clunky and should really be a wakeup call for some people to include a newer base system.

The Windows build of Emacs 24.5 doesn’t ship with SSL and TLS support out of the box. Normally that’s not that much of a problem until you are trying to access marmalade-repo or have org2blog talk to your own blog via SSL/TLS.

Adding SSL and TLS support to the Windows builds of Emacs is easy. SSL/TLS support in the official Emacs build for Windows isn’t enabled because it doesn’t ship with the necessary support libraries, but you can get pre-built binaries from the ezwinports project on Sourceforge. Installation is simple - grab the desired binaries (I used gnutls, but there’s also an older openssl build available) and extract them into the root directory of your Emacs install. The directory layout is the same and mimics the standard Unix directory layout so everything ends up in the correct place.

In a previous blog post I explained how you can substantially improve the performance of git on Windows updating the underlying SSH implementation. This performance improvement is very worthwhile in a standard Unix-style git setup where access to the git repository is done using ssh as the transport layer. For a regular development workstation, this update works fine as long as you keep remembering that you need to check and possibly update the ssh binaries after every git update.

OK, I admit it - I’m a dinosaur. I still use the command line a lot as I’m subscribing to the belief that I can often type faster than I can move my hand off the keyboard to the mouse, click, and move my hand back. Plus, I grew up in an era when the command line was what you got when you turned on the computer, and Windows 2.0 or GEM was a big improvement.

It’s one of those days, thanks to a hard disk going south I ended up having to rebuild the system drive on one of my machines. After putting the important software back on there - “Outlook and Emacs”, as one of my colleagues calls it - I had to reapply some of the usual tweaks that make a generic developer workstation my developer workstation.

One of the changes I wanted to make was to have an “Edit in Emacs” type context menu in Windows Explorer. The only reason I was keeping another editor around was because it’s a feature I use regularly but hadn’t got around to setting up for Emacs.

Admittedly I’m  not the biggest fan of git - I prefer Mercurial - but we’re using it at work and it does a good job as a DVCS. However, we’re mostly a Windows shop and the out of the box performance of Git for Windows is anything but stellar when you are using ssh as the transport for git. That’s not too much bother with most of our repos but we have a couple of fairly big ones and clone performance with those matters.

The Gnu Emacs for Windows distribution appears to be pretty good at inferring where a reasonable place for $HOME is, straight out of the box. In my case, said reasonable place was %USERPROFILE%/AppData/Roaming which was an entirely acceptable default.

That is, until several other tools entered the picture and disagreed with Emacs. We’ve recently switched to using git at work and the git ecosystem  needed to have some ideas where its home was. I’m using Git Extensions as the “regular” Windows GUI and TortoiseGit for the Windows Explorer integration, plus the awesome Posh-Git that even made me learn basic PowerShell.

The default installation of msysgit (aka the official git client for Windows) is unfortunately built without python support. There are understandable reasons as to why this is, starting with “where the heck do I find the various python versions on Windows”. For me the problem was that I needed git-p4 to extract some code history out of a Perforce repository and guess what, git-p4 is written in Python. Only solution for me was that I had to find a way to make this work short of throwing Linux in a VM just to get a git import going.

I was trying to make Windows a little more Emacs-friendly (or was it the other way around?). First step was to enable the emacs server in my .emacs so I could make use of Emacs for quick and dirty editing tasks that require an editor better than Notepad but where the average Emacs startup time was just a little too long to make Emacs a viable alternative. A typical example would be to use Emacs as the editor for commit messages in Mercurial. A quick tweak of my global .hgrc provided me with an appropriate editor setting:
