Janet 1.12.1

on GitHub

This release brings several bug fixes, improvements to threading, os/execute, the getline implementation, and even C++ support with jpm. This means you can easily use C++ in native modules for Janet, as well as standalone mixed Janet and C++ executables.

• Make zero?, one?, pos?, and neg? polymorphic.
• Add C++ support to jpm and improve C++ interop in janet.h.
• Add %t formatter to printf, string/format, and other formatter functions.
• Expose janet_cfuns_prefix in C API.
• Add os/proc-wait and os/proc-kill for interacting with processes.
• Add janet_getjfile to C API.
• Allow redirection of stdin, stdout, and stderr by passing keywords in the env table in os/spawn and os/execute.
• Add os/spawn to get a core/process back instead of an exit code as in os/execute.
  When called like this, os/execute returns immediately.
• Add :x flag to os/execute to raise error when exit code is non-zero.
• Don't run main when flychecking.
• Add :n flag to file/open to raise an error if file cannot be opened.
• Fix import macro to not try and coerce everything to a string.
• Allow passing a second argument to disasm.
• Add cancel. Resumes a fiber but makes it immediately error at the yield point.
• Allow multi-line paste into built in repl.
• Add (curenv).
• Change net/read, net/chunk, and net/write to raise errors in the case of failures.
• Add janet_continue_signal to C API. This indirectly enables C functions that yield to the event loop
  to raise errors or other signals.
• Update meson build script to fix bug on Debian's version of meson
• Add xprint, xprin, xprintf, and xprinf.
• net/write now raises an error message if write fails.
• Fix issue with SIGPIPE on macOS and BSDs.
