0.2.51

This is a minor quality-of-life release.

Bug Fixes

• The IPC server now correctly deletes its UNIX socket after cleanup.
• The IPC server no longer blocks the cleanup process if a worker's socket has been closed by entering a non-blocking state.

Performance Improvements / Refactoring

• std/base64 has been replaced by simdutf. This should, in theory, give us major speedups.
• All the syntactical sugar code has been moved to a separate package called shakar for uniformity.
• Ferus now compiles with Mimalloc as the default memory allocator.

0.2.5

Ferus 0.2.5 is out with about a month's worth of additions and improvements!

Dependencies

Bali

Bumped from 0.6.3 -> master. There are several stability improvements and new features, chief amongst them support for try-except expressions.

Stylus

Bumped from master -> 0.1.3. There is a single new fix that fixes delimiter tokenization in some cases.

0.2.4

It's been quite a while since the last release, hasn't it?

Features

• The old layout engine has been gutted out (AGAIN!) for a new engine that uses Facebook's Yoga layout library.
• Bali has been bumped from 0.3.x to 0.6.3, which brings support for a boat load of JavaScript features, like Set, Number, BigInt, etc. In simpler terms, about 5 months of work (or around 400 commits worth of work) on Bali is now available in Ferus!
• Ferus now supports a subset of CSS3! Currently, only the font-size property is supported, but this list will grow as time passes.

This release is setting in the groundwork for future versions to introduce more CSS features.

0.2.2

This is the first release of Ferus with JavaScript support!
Primitives to modify the DOM with JS are coming next.

Improvements

• The master will no longer be taken down by a hung-up child process
• Child processes will no longer be taken down by a hung-up master

Building Ferus

Ferus requires one external dependency - simdutf

Once that is satisfied, you can run:

$ nimble build

to compile the worker and the master. You must ensure that they're stored in the same directory.

Running Ferus

$ ./ferus <file or URL>
