#Native emacs editor for windows upgrade#

IвЂ™ve been using the origin/native-comp branch in the Emacs git tree for a while now and IвЂ™ve not experienced any issues. I believe this change is a significant step forward, even with the added dependencies in the build chain on libgccjit. UPDATE: Great news! The native compilation branch is now merged into EmacsвЂ™s master branch and is slated for inclusion in Emacs 28. However, one change that did not make it into Emacs 27 вЂ“ and the topic of todayвЂ™s blog post вЂ“ is an exciting experimental feature called вЂњnative compilation.вЂќ Briefly, Andrea Corallo discovered that you can use GCC to compile Emacs Lisp and reap the benefits of the speedups and, with a generous amount of elbow grease from Andrea over the past year, very few downsides - except the initial compilation speed, but more on that in a moment.

If youвЂ™re a heavy user of lsp-mode or eglot then I highly recommend you upgrade for that reason alone. There are some ministrations that balm the performance pains, though: Emacs 27 now supports libjansson, a C library for working with JSON. Common sources of performance bottlenecks include completion frameworks the Emacs client libraries that talk to Language Servers and other highly trafficked code paths used widely in EmacsвЂ™s many packages. Cyril Northcote Parkinson wrote in his book ParkinsonвЂ™s Law that вЂњwork expands so as to fill the time available for its completion.вЂќ If you squint your eyes, youвЂ™ll see that this is also the case for modern software, and in particular Emacs.ДЇor every incrementation in performance, there will be a new gizmo to dial it back down again.
