glaucus-s6-x86-64-v3-28042023

[firasuke]

What's new?

This release is a modest attempt to follow a regular release cycle for glaucus.

A summary of changes that took place:

• radula was rewritten in Nim (previous version was in Rust), reasons for this include:
  • code is reasonably more readable (more so than the Rust version)
  • much less LOC even with more features added (compared to the Rust version)
  • code is written in a reasonable amount of time (much less than Rust version, again the rewrite itself took about a month, but the speed at which newer features was added is like 4 - 8 times faster than the time it took me to implement them in Rust, probably because I suck in Rust even after a year of using it, but who knows...)
  • uses less system resources (1/3 of what the Rust version uses)
  • much smaller executable size (200 to 300 KB) (compared to the Rust version 3 MB)
  • can be built using glaucus's existing toolchain because Nim transpiles to C; thus, making use of the optimized toolchain glaucus uses (unlike Rust which is very hard to bootstrap, and does not work all that great with shared musl...)
  • slightly faster (parsing cerata is around 6 - 20% faster overall) (this is probably because I suck with Rust even after a year of using it, but then again I've only been writing in Nim for a month or two so...)
• glaucus's toolchain now uses mold by default, and all executables (with the exception of the Linux kernel) are being linked with it
• glaucus now uses yash as the default shell for interactive use instead of oksh for the following reasons:
  • more strict POSIX compliance compared to oksh
  • much more user friendly compared to oksh
  • about 50% the size of bash and only slightly bigger (10 - 20%) than oksh
  • about 30 - 40% faster than bash and has identical performance to oksh and loksh
  • multiline support, which is not available in oksh
• glaucus now uses OpenBSD M4 as the default M4 implementation
• glaucus now uses BLAKE3 as the default hashing algorithm instead of SHA-512
• Update default ASCII art
• Updated cerata

This release is more stable compared to previous releases but it still is not production ready.
