JJ Merelo has taken the initiative (again, so kudos!) to set up a list of Google Summer of Code proposals for the Raku Programming Language. The following proposals have arrived already:
Create a libgccjitbackend for MoarVM’s Just In Time compiler
- Moving Raku to GTK 4.0
- Create a Raku Data Analysis library
- Create a Raku implementation of a gRPC client
Please add your proposals as Pull Requests to the GSOC-2021-ideas repository!
Raku CI integration bot Grant Proposal
Patrick Böker has submitted a Grant Proposal to create a Raku CI Bot to orchestrate the testing process of the Rakudo, NQP and MoarVM projects. Please leave your comments on this project proposal, as it will help the Grants Committee to make a decision!
Comma Community Release
This quarter’s release of Comma Community (the IDE of choice for the Raku Programming Language) brings a number of welcome improvements: new code analyses include annotating calls to deprecated routines (those annotated with the
is DEPRECATED trait), passing the wrong number of arguments or mismatched named arguments to a routine, assignment to a readonly parameter, and use of
self in a context where it is not available (examples).
Meanwhile, writing code gets more convenient. The ASCII to Unicode conversion support that arrived in the previous release has been extended, and now covers hyper operators and terms like
pi. When a call to an unknown sub is detected, there’s now a quickfix to stub it. When a sub is annotated as unused, there are quickfixes to delete it or add the
is export trait. A new intention allows switching between fat arrow and colon pair syntax.
Comma’s type inference has improved too, the most visible improvement being that a
for loop over a typed array will provide completion and code navigation on the iteration variable based upon the element type. And, as usual, there’s a whole bunch of smaller improvements and fixes across the IDE.
FOSDEM this weekend
