- Fixed thread starvation in Jupyter integration on systems with few CPUs.
- Support interrupting execution in Jupyter notebook. Process gets terminated, so variables are lost, but other state is preserved.
- Support interrupting execution in REPL by pressing ctrl-c.
- Updated rust-analyzer.
:deplines can now be commented out without breaking subsequent:deplines. Thanks JohnScience!- Reduced interleaving of stdout and stderr.
- Errors now render using ariadne, giving a much nicer presentation. Thanks HKalbasi!
- Small speedup in execution time by bypassing rustup.
preserve_vars_on_panicis now true by default (as it used to be). It now works much better than before, with all variables being preserved if a panic occurs.- By using rustyline's new external printer API, stderr output that hasn't been displayed before we return to the prompt no longer messes up the prompt. In fact, you can now spawn a thread that writes to stderr in the background and the output now appears above your prompt.
- Jupyter kernel now uses a native Rust library for ZMQ, so no longer requires cmake to build.
- The last bit of code that tried to use rustc error messages to determine variable types has been deleted. Now if rust-analyzer can't determine the type of a variable, we ask the user to add an explicit type annotation.
- Update rust-analyzer
- Building evcxr now requires rust 1.63 or higher.
- Added a release workflow so that binaries for the latest Linux (built on Ubuntu), Windows and Mac are available for download on the releases page.
- Now uses Rust edition 2021.
- MSRV is now 1.59.
- Changed completion type in REPL to
list. See evcxr_repl/README.md if you'd like the old behavior. - Update to latest rust-analyzer - const generics now work reasonably well!
- Fix escaping of ampersands in HTML output - Thanks Tim McNamara.
- Use mold for linking if of path - Thanks Will Eaton.
- Fix inline errors showing up for await calls in Jupyter notebook.

- Update to latest rust-analyzer.
- Minimum supported rust version is now 1.55 due to changes in rust-analyzer.
- Update rust-analyzer - fixes a compilation failure.
- Support for crate-level attributes - e.g.
#![feature(...)] - Minimum supported rust version is now 1.53 due to changes in rust-analyzer.
- Use mimalloc. This reduces startup time, at least one Mac. Thanks thomcc.
- Initialize CommandContext in the background. Reduces startup time. Thanks thomcc.
- Updated rustyline. Thanks thomcc
- Use rust-analyzer for infering types for let destructurings.
- Update rust-analyzer. Fixes evcxr on nightly, beta (and next stable release).
- Minimum supported rust version now 1.52 (required for latest rust-analyzer).
- Fix relative paths in deps. Thanks Max Göttlicher!
- Use explicit types for variables when supplied. This is currently required for variables that use const generics.
- Minimum rust version is now 1.51 (since upstream crates are already using const generics).
- Don't misuse JUPYTER_CONFIG_DIR.
- Make
a = 10(no semicolon or let) report an error. - Updated rust-analyzer
- Fixed bug that was affecting HTML export from Jupyter. #153
- Updated rust-analyzer.
- Jupyter kernel now shows errors and warnings inline as you type by running cargo check on the
backend. Running
evcxr\_jupyter --installbefore starting jupyter notebook is recommended. It will auto-update when the evcxr jupyter kernel starts, however that update may not effect the current session. - Fixed
:clearcommand. - Work around imprecise timestamps on Macs that use a HPFS filesystem
- Added
:toolchaincommand to allow specifying rust compiler toolchains (e.g. "nightly"). - Added
:offlineto turn on offline mode when running Cargo. - Various improvements to error reporting.
- Fixed a number of bugs in tab completion.
- Documentation improvements. Thanks Ibraheem!
- Fixed a panic when doing tab completion after loading a crate with a hyphenated name.
- Changed internal parsing logic to use rust-analyzer instead of syn (reduced binary size from 24MB to 20MB).
- Improved semantics for use statements. e.g.
use a::{b, c};followed byuse a::{b, c, d}now won't give you errors. - API changes in the evcxr crate (used by the repl and jupyter kernel).
- Support for rustc 1.48.
- Tab completion based on rust-analyzer (in both Jupyter kernel and REPL).
- Minimum rust version is now 1.46
- Now requires rust-src component
- rustup component add rust-src
- Jupyter kernel now supports prompting for input.
- REPL now supports the quit command. Thanks komi
- Fix for a crash in the REPL when certain multiline error were encountered.
- REPL now supports
--edit-mode vithanks to aminroosta - REPL now has history-based tab completion thanks to aminroosta
- Works on FreeBSD. Thanks dmilith!
- Multiline errors look much better in the REPL thanks to aminroosta!
- Improved cursor navigation in REPL thanks to Ma27!
- Fixed colored text outputs on Windows. Thanks Mirko and Dmitry!
- Supports async / await using Tokio as the executor.
- Question mark operator can now be used (errors are printed to stderr).
- Now requires rustc >= 1.40.0
- REPL now support multiline input (thanks Thom Chiovoloni!)
- Don't use lld on MacOS, it's broken (thanks Thom Chiovoloni for figuring this out)
- Fixed segfault if executing code without variables followed by code with variables.
- Automatically use lld if it's installed. Use :linker command to override.
- Handle variables that contain type inference placeholders
_. - Added support for overriding the config dir with the environment variable EVCXR_CONFIG_DIR (thanks Thom Chiovoloni).
- Run prelude.rs after init.evcxr if one exists (thanks Thom Chiovoloni).
- Allow output format to be specified. e.g. :fmt {:#?} (thanks κeen)
- Fixes to work with rust 1.41
- Improved handling of cargo workspaces.
- Now works if the user has overridden Cargo's default target directory (thanks Aloxaf).
- Fixed prompt color (thanks Dmitry Murzin).
- Added a flag to disable use of readline (thanks Dmitry Murzin).
- Fix for binder (thanks Luiz Irber)
- Escape reserved words "async" and "try" when encountered in types.
- Use vendored ZMQ library by default.
- Now support sccache.
- These release notes previously said that this release added support for mixing commands like :dep with code. That feature was actually added a long time ago by David Bernard. Thanks David, and sorry for the confusion.
- No longer preserves variables on panic by default.
- Turns out this was significantly slowing down compilation.
- You can get back the old behavior with
:preserve_vars_on_panic 1 - Put that in your ~/.config/evcxr/init.evcxr or equivalent to always have it.
- Optimization is now back on by default. With the above change, there's now not really any noticable difference in eval times for small amounts of code.
- Fixed runtime error on windows due to something not liking the dll having been renamed.
- Added option :preserve_vars_on_panic, which still defaults to on, but which if turned off will speed up some compilations at the expense of all variables being lost if a panic occurs.
- Revert change to not preserve copy variables on panic as it broke mutation of copy variables. Will reenable in future once it's properly fixed.
- Optimization is now off by default, since many people using a REPL or Jupyter
kernel are experimenting and faster compile times are more important than
faster runtimes.
- If you want it always on, see README.md for how to do that.
- New execution model.
- A single crate is now reused for all compilation. This is a bit faster than the old model where each execution was a separate crate that had a dependency on the previous crates.
- Defined items no longer need to be pub.
- Optimization level can now be set (as opposed to just toggled).
- Reads commands (one per line) from a startup file.
- e.g. ~/.config/evcxr/init.evcxr (on Linux)
- Now uses Rust 2018 edition.
- Don't preserve variables that are Copy on panic.
- Results in a small speedup in some evaluation times.
- If you really want this, you can opt back in via :preserve_copy_types.
- Fix for another upcoming cargo change (due in 1.37).
- Fix with upcomming beta release (1.36) where Cargo started intercepting and wrapping JSON errors from the compiler.
- Give proper error message if a closure or an impl trait is stored into a variable.
- Recover from compilation failure in a case where we previously got out-of-sync with what variables should exist.
- Windows and Mac support! Big thanks to Daniel Griffen for the final fixes and David Bernard for Travis setup.
- Fixed handling of crates with "-" in their name.
- Support relative crate paths.
- Don't error if the same extern crate is given multiple times with slightly different formatting.
- Fix optimization (wasn't actually working before for some reason).
- Give better error message if rustc suggests a private type for a variable.
- Allow variables to be given explicit types.
- A couple of fixes for Windows (probaly not enough for it to actually work though, but it's a start).
- Support for running in Binder.
- :dep no longer automatically adds extern crate. extern crate still automatically adds a dependency, but only if there isn't already a library with the specified name.
- Including ":help" command now works properly in the Jupyter kernel.
- Various fixes related to running on MacOS.
- Numerous other improvements to the Jupyter kernel, in particular making it work with Jupyter Lab.
