    Cool small features in Emacs 30 that I really like:

    • If you have ever tried to create a custom modeline, you may have discovered that right-aligning elements was a massive pain. Emacs 30 adds a new modeline element mode-line-format-right-align which makes all subsequent elements in mode-line-format right-aligned.
    • When Emacs prompts you about recovering an auto-save file, you can now press = to show a diff between the buffer and auto-save. No more guessing whether you had done anything important.
    • E in dired opens a file with the default program for that file type (via xdg-open or OS equivalent).

    Emacs 30 is a more low-key release compared to heavy hitting features like native compilation in 28 and Tree-sitter in 29. Probably the headline change is replacing the libjansson based JSON parser with a homegrown one that is several times (~8x) faster, which will significantly benefit features like LSP. This will also mark the official release of the Android port, as well as the usual scattershot of improvements across the board. The NEWS file has the full changelog.

    The reason that Doom is so portable goes beyond Linux and is an artefact of its development. id developed Doom on NeXTSTEP (i.e. Unix) machines and obviously targeted DOS. This is pretty unique among DOS games at the time and required id to write as much code as possible in a platform agnostic way. This means that the main engine does not care about where it is running and the usual DOS hacks are contained to DOS-specific files. In order to port Doom to a new platform, ideally one only needs to rewrite the system-specific implementation files for video, sound, filesystem access, etc., and this mostly holds true today. (These files are prefixed with i_ in the Doom source).

    The Linux port is just one of many versions developed at the time. I don’t believe that it was commercially released; it was more of a portability test. The reason that the Linux version was chosen for the source release over the DOS version was because it didn’t rely on the proprietary DMX sound library that the DOS port used.









  • Emacs’s regular clipboard is the “kill ring” which also allows you to retrieve any previously cut/copied text. It also has “registers” where you can store and retrieve snippets of text, which can be considered clipboards when used for this purpose. Registers can be referenced by any character you can type on your keyboard, including control characters like ^D.

    This totals… a lot of clipboards.

    I think that this is above all else the reason that I use Arch. Arch Linux makes creating packages trivial, basically just wrapping build instructions into a shell script template. Arch handles the rest. The build systems for deb or rpm packages don’t come close, and good luck rolling your own flatpak.

    This allows me to use pacman for everything outside of my home directory. Pacman is practically the central feature of my computer, and it’s wonderful. I’m sure those Nix people can relate, though I guess my method is a bit less robust.
