CHANGELOG.md
View File

@ -3,6 +3,18 @@ All notable changes to this project will be documented in this file.
## Unreleased - ???
- Silence warnings in some compilers.
- 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.
