Janet 1.35.0

[bakpakin]

1.35.0 - 2024-06-15

• Add :only argument to import to allow for easier control over imported bindings.
• Add extra optional env argument to eval and eval-string.
• Allow naming function literals with a keyword. This allows better stacktraces for macros without
  accidentally adding new bindings.
• Add bundle/ module for managing packages within Janet. This should replace the jpm packaging
  format eventually and is much simpler and amenable to more complicated builds.
• Add macros ev/with-lock, ev/with-rlock, and ev/with-wlock for using mutexes and rwlocks.
• Add with-env
• Add *module-make-env*dynamic binding
• Add buffer/format-at
• Add long form command line options for readable CLI usage
• Fix bug with net/accept-loop that would sometimes miss connections.

This discussion was created from the release Janet 1.35.0.

I really like the :only option for (import). Allowing long-form CLI options is a great improvement as well. 👍 Thanks for the release!

[sogaiu]

I agree.

On a side note, has anyone figured out a way to use the :only feature without having to quote things?

What I got working was:

(import spork/fmt :only ['format])

Losing the quote gave me a compile error:

$ janet
Janet 1.35.0-0d9e9991 linux/x64/gcc - '(doc)' for help
repl:1:> (import spork/fmt :only [format])
repl:1:25: compile error: unknown symbol format

Side note to a side note (^^;

Cool use of invert to make a "set" in merge-module's source!

[CFiggers]

It looks like you can quote the whole tuple to avoid the compiler error:

$ janet
Janet 1.35.0-0d9e9991 linux/x64/gcc - '(doc)' for help
repl:1:> (import spork/path :only '[abspath join])
@{_ @{:value <cycle 0>} path/abspath @{:private true} path/join @{:private true}}

Still requires a quote, but at least you can use only one instead of needing to quote every symbol individually.

[sogaiu]

Thanks!

That's much better.

[sogaiu]

Looks like the quoting may not be necessary starting in 1.35.2.

[sivers]

Can bundle currently be used instead of jpm to install libraries like circlet and janet-pq that have .c files?

[sogaiu]

I don't think there is any network fetching, but I think this sample file shows how if one applies bits in spork, compilation of .c is possible.

Perhaps known already, but more discussion is/was here.
