James Cherti has announced a new package, Compile Angel. The idea is to keep all your Elisp files compiled with both the byte compiler and the native compiler. It has modes to compile any outdated “binaries” when a modified Elisp file is saved or when one is loaded. Both compilations are important because byte compilation helps Emacs to load faster while native compilation, of course, help Emacs run faster by generating native hardware code.
In his announcement, Cherti explains how Compile Angel differs from auto-compile. The TL;DR is that Compile Angel is lighter weight and compiles more files than auto-compile.
This seems like a nice package. Strictly speaking, it’s not necessary, of course, but it’s another way reducing the friction of maintaining your Emacs installation. Unless you’re the type of person who enjoys a completely hands-on approach to system maintenance, Compile Angel is probably worth looking into.
The project GitHub repository is here but except for the code is essentially the same as the announcement.
