Prologue

\n\t

\n\t In this blog, I'll show you how to compile Emacs on\nGNU/Linux Debian 12. But the procedure is of course easily adaptable\nto any GNU/Linux OS, since we'll only be installing a few packages\nusing their package manager. To make everything tutti , we will also\n\t add a native compiler and tree-sitter.\n
\n

Native compilation

\na€¦in Emacs is the process of translating and converting Emacs Lisp source code to machine code, which allows Emacs Lisp to run more efficiently and faster each time it is run.\n
\nNative compilation in Emacs is not a new feature; it was introduced in version 28.1.\n
\nThe result of native compilation is a binary blob that (can) be subsequently loaded when Emacs starts.\n
\n
\n

Tree-sitter

\n\nTree-sitter is a syntax tree analysis library used to parse code as it\nis manipulated. It is a tool that allows you to analyze the syntax\nstructure of a programming language and provides an interface to\nperform various operations such as code refactoring, dependency\nvisualization, or documentation generation.\n\nTree-sitter supports different programming languages and allows users\nto define their own "recipes".\n\nNormally, when working with code (meaning highlighting it, folding it,\nmoving it to definitions,a€¦) some kind of parser working with regular\nexpressions was used.\n\nTree-sitter (supposedly) provides better parsing than a regular\nexpression parser. Regular expressions work with characters or a group\nof characters, and these must appear in the displayed text in a\ndefined order. However, a tree-sitter is capable of parsing and\nrecognizing more complex patterns of structured language, including\nsyntax.\n\nThe regular expression parser requires that the entire input text be\nread and processed at once, which is memory and computing power\nintensive when dealing with large files. Tree-sitter works\nincrementally and performs parsing without the need to load the entire\ntext at once.\n\nThe regular expression parser only works with the linear structure of\nthe text and cannot capture its hierarchy. Tree-sitter is able to\nunderstand the hierarchical structure of the text and provide\ninformation about different levels of structure - such as nested code\nblocks and so on.\n
\n

Installation

\n
\n

Installing the necessary tools and libraries

\n\nTo successfully compile GNU Emacs, we will need some additional tools\nand libraries that may not be present in a normal OS installation.\n\n \n\nThese are:\n\n

\n| git              | tool for storing, managing and tracking changes to project source code                                |\n| autoconf         | (simplified) used to generate a Makefile file for compilation                                         |\n| texinfo          | tool for working with and converting documentation                                                    |\n| gnutls-bin       | libraries for using SSL/TLS protocols (if we want to use Emacs as a mail client)                      |\n| libgccjit-12-dev | library containing the language independent JIT (Just-In-Time) compiler needed for native compilation |\n| gcc              | is probably not necessary to introduce the C compiler                                                 |\n| libgtk2.0-dev    | GTK libraries if Emacs is to run in its own rendered window and not in the terminal                   |\n| libgnutls28-dev  | libraries for compiling for gnutls-bin                                                                |\n| libxpm-dev       | libraries to support xpm graphics filesknižnice pre podporu xpm grafických súborov                    |\n| libgif-dev       | a€¦ and detto for gif                                                                                   |\n| libtinfo-dev     | transition package for libncurses                                                                     |\n

\n
\nWithout hesitation or second thoughts 😏, we copy the command:\n

\n  sudo apt install git autoconf make texinfo gnutls-bin libgccjit-12-dev gcc libgtk2.0-dev libgnutls28-dev lib libxpm-dev libgif-dev

\n

\n\n

Tree-sitter

\n\nAccording to the tutorial on [Mastering Emacs: How to Get Started with Tree-Sitter](https://www.masteringemacs.org/article/how-to-get-started-tree- sitter):\n
\nDownload the latest version of tree-sitter:\n\n

\n  git clone https://github.com/tree-sitter/tree-sitter.git

\n
\nAnd compile the program using the familiar three-line magic:\n
\n

\n  cd tree-sitter/\n  make\n  sudo make install\n

\n
\nAnd (if we haven't already) if we define one more variable so that Emacs doesn't fiddle during starting up:\n

\n  export LD_LIBRARY_PATH=/usr/local/lib/\n

\n
\n\n

GNU Emacs 30

\n\nFrom the savannah repositories we'll download the Emacs source code:\n

\n  git clone -b master git://git.sv.gnu.org/emacs.git\n

\n
\nNext up:\n

\n  cd emacs\n

\n
\nRun autogen.sh , which is used to generate configuration files and scripts for compilation and installation\n
\n

\n  ./autogen.sh\n

\n
\nAnd then we run configure , with parameters\nfor tree-sitter support and native compilation. \n\n
\n

\n  ./configure --with-tree-sitter --with-native-compilation --with-mailutils --with-pop\n

\n\n( --with-pop - if we also require POP3 protocol when downloading emails)\n
\n \nFollowed by the classic:\n

\n  make\n  sudo make install\n

\n
\n

Tree-sitter setting

\n
\n\nSomewhere in the initialization file, we put a list of addresses from where the rules for that language can be downloaded:\n

\n  (setq treesit-language-source-alist\n    \'((bash "https://github.com/tree-sitter/tree-sitter-bash"))\n     (cmake "https://github.com/uyha/tree-sitter-cmake")\n     (c "https://github.com/tree-sitter/tree-sitter-c")\n     (css "https://github.com/tree-sitter/tree-sitter-css")\n     (elisp "https://github.com/Wilfred/tree-sitter-elisp")\n     (go "https://github.com/tree-sitter/tree-sitter-go")\n     (html "https://github.com/tree-sitter/tree-sitter-html")\n     (javascript "https://github.com/tree-sitter/tree-sitter-javascript" "master" "src")\n     (json "https://github.com/tree-sitter/tree-sitter-json")\n     (make "https://github.com/alemuller/tree-sitter-make")\n     (markdown "https://github.com/ikatyang/tree-sitter-markdown")\n     (python "https://github.com/tree-sitter/tree-sitter-python")\n     (toml "https://github.com/tree-sitter/tree-sitter-toml")\n     (tsx "https://github.com/tree-sitter/tree-sitter-typescript" "master" "tsx/src")\n     (typescript "https://github.com/tree-sitter/tree-sitter-typescript" "master" "typescript/src")\n     (yaml "https://github.com/ikatyang/tree-sitter-yaml")))\n

\n
\nAnd run the\n

\n  M-x treesit-install-language-grammar\n

command.\n
\n
\n\nWell, we have compiled Emacs in versiona€¦ well, last version, for me it was testing version 30.\n\nBut I haven't deployed it to full operation yet.\n\n\t

So the issue that I'm having wasn't entirely noticeable at first, so I didn't realize that I might need to revert something until I went ahead and made a lot more changes to my install. I've learned something here about the value of a GitHub repo to store my configurations.

So as of five days ago, I had a perfectly functional KDE Plasma NixOS daily driver. I recall having an issue with Discord and crackling audio that resulted me toggling some pulse audio and pipewire options to avoid a conflict. It seemed to work. Then on the next day, I did nix-channel --update and nixos-rebuild switch --upgrade just because I wanted to update since it'd been awhile.

We then had a situation where we had to adopt a dog for re-homing, so I didn't spend long with these changes. A few days later, I've finally been able to settle down and use my computer again, but I'm noticing that SO MUCH of my UI is being ridiculously slow to respond. Mostly my Application Launcher and the password prompt to login. But it's pervasive through most apps except Firefox (thankfully, so I can post this).

If I load the generation from the 8th, everything behaves just as expected. But unfortunately, I do not have the configuration.nix from that day or any day prior to now. But I have a decent recollection of what I've changed in the configuration file since. Regardless, nothing I do seems to resolve it. I'm not sure if the channel and package upgrades did something that isn't under the configuration.nix file's control.

Any help is appreciated. I will post my sanitized configuration.nix below. Any other feedback for optimizations is more than welcome. Thanks.
