Recently, after each rebuild, I noticed that Emacs' total installation
size has become bigger overtime. That's understandably unavoidable but
there's room for improvement. By analyzing disk usage I discovered
that:
"lisp/leim/"'s compiled elisp files are taking the most significant disk
storage.
By inspecting some of those, I don't think we are able to gain any
practical benefit by compiling them, they don't contain (~)any
function/macro definitions at all.
So I try to disable byte-compilation (by either dir-local vars or
file-local vars) in:
- lisp/leim/ : I disable for the whole directory
And some more .el(s) that I don't find so essential to compile:
- lisp/play/ : not so serious or critical to workflows
- lisp/cedet/{ede,semantic,srecode}/ : we now have LSP/eglot!
- lisp/cedet/{ede.el,semantic.el} : same as above, also a big file by
itself
(I wished pulse.el, mode-local.el, data-debug.el were moved out of this
lisp/cedet/, then putting a single .dir-local.el there would be the
simplest)
- lisp/obsolete/ : already obsolete anyway, but some packages may still
depend on them so no-native-compile only
Then build Emacs again.
The final size of my Emacs installation, compared to before applying
those no-compile local variables:
298.79 MiB -> 253.09 MiB
That's 45.7 MiB disk saved. About 15.3% of total shaved!
Please consider at least "lisp/leim/"'s gigantic files such as
"ZIRANMA.el", "ARRAY30.el", "ja-dic.el" ,etc. as I find those the most
disk-expensive when compiled, yet questionable benefit and waste of time
spending to build.
