The path and functions builtins have been ported, as well as some of the spawn machinery and the last pieces of the killring.

@chfkch I would be interested in contributing, but I can't promise that I get time to do so :/

Not a lot of movement this week, with some of our committers on break. Personally, I decided it is more important (but less interesting) for me to work on getting a release of the old codebase out than porting little builtins.

The string builtin port has been merged, which has seen the removal of a lot of C++. There's PRs in for another few builtins but no review as yet. There's work being done on the port of the parser but there's a huge chunk of interlinked code.

I think the string builtin is interesting when you look at fish's history. Under the 1.x design goals it would never have been added - there's already enough string manipulation tools in the standard Unix toolkit. Under the newer guidelines, there's clearly a place for a unified command with consistent UI and the improved performance in loops that comes from builtins.

@zanchey

How does the code-base continue working if you progressively replace C++ with Rust? Are you going class-by-class, module-by-module and have some inter-language communication? Or are these separate services? Is there more information about this process?

The function module and its accompanying builtin have been ported. The string builtin PR edges ever closer to being merged (and currently removes nearly 3000 lines of C++).

No new areas ported this week but some refactoring and cleanup, including some unused C++. Any claims that I went looking for unused C++ just to enlarge my progress bar are unfounded.

Some work on parallelising the tests. I've ported the cd builtin, and the hype is real - Rust's error messages really are good, and if it compiles it's most of the way to working. Already feel confident in Rust in a way I never did in C++.

Port of status builtin has been merged, string is still in progress. I tried to do some work on the input side and there's a lot of global variables to be untangled.

Nothing new merged since last report, but there's a PR in for the output module and the set_color builtin.

The tiny print_help module and the killring module have been ported. There's been a lot of discussion around some of the supporting data structures.

The env_dispatch port has been merged. This took a lot of work from the author and reviewers!

Haters (colleagues) continue to attack (provide reasoned discussion on) my methodology for measuring our progress. I don't see them getting dozens (dozens!) of stars though.

The most important port this week was my shell script which generates the progress updates. Rewriting in Rust slashed 50% off the (40 msec) runtime.

Also the test builtin, which has maybe the worst UI in the history of shell commands.

Nothing major merged this week, but the gnarly env_dispatch module, which handles propagating environment changes, is nearly ready for merge. There's a lot of work being done on the parser but that's hard to port in parts.

The threading and signal handling modules have been ported. These are both pretty tricky areas. Environment variable handling and the actual parser look like they're on the way.

@hjvt it's mostly grinding away through the various modules at the moment. If you've got CXX/autocxx experience that would probably help. We've had a few new contributors who aren't finding it too hard to navigate.
