brush v0.3.0

🚀 Release Notes

This is a major release, containing architectural improvements and compatibility-focused features and fixes. A big thanks to all of the contributors over the last few months, including issue filers, question-askers, and code contributors 🙏.

Based on user-filed issues (thank you!), targeted work went into improving compatibility with popular tools like fzf and neofetch.

Additionally, a significant amount of work went into refactoring and improving usability of the public API surface within the crate-based libraries that make up brush's core. These come with breaking changes for programmatic clients, but we're confident they will come with significant benefit.

The following summary covers the most notable changes and the full change details are below.

✅ Features and Improvements

Builtins

• The fc builtin received its initial implementation!
• bind implementation received support for binding key sequences to readline functions (e.g., "\C-a":beginning-of-line).
• trap now fully implements the EXIT trap.

Standard variables

• Basic support for use of BASH_XTRACEFD was added. A new command-line parameter to brush (--inherit-fd) enables allow-listing inherited file descriptors for use within the shell.

Control flow

• Support for an undocumented C-like syntax for arithmetic for loops has been implemented for improved compatibility.

🪳 Notable bug fixes

• Fixes for quote handling of \' in double-quoted word contexts.
• Targeted fixes to history importing make it more robust against non-UTF8 compatible text.
• Fixes for parsing of here-documents in quoted command substitutions.
• Fixes for nuanced quote removal in parameter expressions with replacements (e.g., "${var:+'x'}").
• Fixes for command substitution expansions resulting in spawning processes with large volumes of output (e.g., $(emit-a-lot-of-text)).
• Updates to the open file table made by commandless exec (e.g., exec 2>/dev/null) are now reflected immediately, even when in a loop context.

🚧 API Changes

Changes in this section pertain to programmatic clients of the brush-core, brush-parser, and brush-interactive crates. They do not apply to application-level shell users.

brush-builtins

All shell builtins have been moved into a new dedicated brush-builtins crate. With this move, significant refactoring was done to ensure that these builtins are all implementable using public APIs exposed by brush-core. In doing so, this also significantly advanced the richness of the latter APIs.

Important

Programmatic clients of the brush-core crate will find that a constructed Shell is not automatically populated with the usual set of builtins. New optional APIs exist in the brush-builtins crate to retrieve default builtins and in brush-core to register them with a Shell instance.

Parsing and AST

As an important step on our journey to evolve brush's parsers, @lu_zero has made contributions that start enriching our parsed Abstract Syntax Trees (ASTs) with links back to the source text. As part of this work, a new SourceLocation trait was introduced and implemented for many AST node types. Work will continue in the coming releases.

API Ergonomics

To improve ergonomics, we've introduce builder-based construction utilities to key structures like brush_core::Shell. We will continue to expand on this adoption over time to simplify the work of constructing these values.

Note that the signature of Shell::new() has changed and may require adjustment in callers.

Error handling

As preparatory work for future improvements, we've overhauled the core error types and execution result types in brush-core:

• Error has been renamed to ErrorKind, with a new wrapping Error struct type that can carry additional context. This will be used in the future for improved diagnostics.

• Clients of brush-core can now provide their own custom error formatter to render a displayable string from an Error value. This will be used by some of our frontends for fancier diagnostics in the future. It also decouples error formatting from writing.

• Multiple overlapping result types across the core interpreter, command utilities, and builtins have been consolidated into a coherent set of ExecutionResult, ExecutionExitCode, and ExecutionControlFlow types. Along the way a handful of bugs for edge cases were identified and resolved as part of the streamlining.

brush v0.2.20

🚀 Release Notes

This release includes a targeted change to the project's default compiler flags (see #600 for details). Prior to this change, release builds defaulted to optimizing for the build host's hardware platform; while useful for individuals, this is problematic for users who plan to use the built binaries on a different system.

Notable features and fixes:

• Fixed "illegal instruction" issue sometimes seen when building brush on one system and running on another. (Thanks to @kachick for diagnosing and fixing this!)
• Added support for +o/-o on the brush command line.
• Corrected behavior of positional parameter shadowing with source/. builtin.

Notable API improvements:

• Ergonomics improvements to Shell::invoke_function, ShellValue construction, and a few other places. (Thanks to @Elsie19 for contributions here!)

brush v0.2.19

🚀 Release Notes

This release included a batch of compatibility fixes, ergonomics improvements to the API surfaces of brush-core and brush-parser crates, and some targeted performance improvements.

Notable features:

• Add BRUSH_VERSION variable to distinguish versions of brush from the version of bash it targets compatibility with. (Thanks to @kachick for proposing and implementing this one.)
• API adjustments to script parsing in brush-core for ergonomics. (Thanks to @hwittenborn for contributing this.)
• Initial (non-translating) support for gettext quoted strings. (Thanks to @Elsie19 for identifying this gap and merging in an initial implementation.)
• Overhaul of printf builtin using the uucore crate from the Rust coreutils project.
• Added support for >&-, >&N-, and other bash-extended redirection forms.

Highlighted fixes:

• Correct handling of escape sequences in ANSI-C strings.
• Handle here documents terminated by EOF (Thanks to @mati865 for reporting this.)
• Fix behavior of brush when commands are piped to stdin. (Thanks to @andychu for catching and reporting this.)

Other shout-outs:

• Big shout-out to @andychu for onboarding brush to the Oils project's cross-shell compatibility testing! More discussion of this can be found here.

brush v0.2.18

🚀 Release Notes

Since our last release we've seen an influx of interest, thanks in part to getting posted to Hacker News and elsewhere. Welcome all! We appreciate your interest, questions, filed issues, and support 😄

This release focuses on a wave of fixes to address some of the user feedback we've received, as well as some targeted features that had been on our backlog for quite some time.
Some select highlights:

• Ergonomic improvements to the brush-core exported API surface for applications embedding brush. (Particular thanks to @Elsie19 and other contributors on this).
• Support for logical/physical options (-L, -P) to cd, pwd, et al. (This builds on the work that @39555 started several months back; thanks for your patience until we were able to get to it!)
• Significant improvements to the mapfile/readarray builtin. (Thanks to @Elsie19 on overhauling mapfile's core input loop.)
• Initial implementation of the ulimit builtin. (Thanks to @lu-zero for getting it from unimplemented to something reasonable.)
• Initial implementation of bind -x support, used by many shell extensions and users' .bashrc files; there's more to do, but this covers a long asked-for feature request from the community.

There's plenty more bug fixes and changes -- as usual, the full details are below. And a big shout-out to our new contributors as well as contributors who dove in deeper this cycle! 🙏

Release Notes

This release brings an assortment of fixes for reported compatibility issues and an upgrade of reedline to 0.39.0. Most notably:

• arithmetic expressions support base#literal syntax for integer literals
• $PS4 is prompt-expanded when used in set -x et al.
• command -p is now implemented
• targeted fixes to support running our compatibility test suite in more environments (e.g., NixOS)

Release Notes

Another release with a sizable number of targeted fixes for posted issues, performance tweaks, and a couple of smaller features. The most noticeable feature may be the introduction of "dynamic variables" into the shell implementation, which allowed us to add quick support for standard special variables like $SHELLOPTS, $BASHOPTS, et al.
