v6.1

This release sees a massive jump in event-driven capabilities as well as several new features and bug fixes.

Breaking Changes

  • core: FID output refactored in runtime and debug. However the output of these builtins shouldn't be depended on as a stable API. They exist for manual inspection and debugging

  • runtime: --flush-cache flag has been renamed to --clear-cache

  • events: key names for namespaced events switched from interrupt_name to name.interrupt. The only event impacted by this change is onPrompt and even there, the only time this change should be noticeable is when manually removing an event read more

  • ANSI Constants: {F1}, {F2}, {F3}, {F4} now produce the same escape sequences as {F1-VT100} (...and so on). This is to bring F1 to F4 keys inline with xterm, and thus all other compatible terminal emulators. You can still use the previous escape codes via {F1-VT220} (...and so on). {F5} and above are unchanged (read more)

Deprecation Warnings

Please read out compatibility commitment to understand how features are deprecated.

  • the ? pipe will be deprecated to make way for a the ternary operator. You can achieve the same result with <err> <!out>, eg command <err> <!out> parameters... | next-command ...

  • the = and let builtins are now officially deprecated. They've been marked as deprecated in the documentation for a couple of years but you'll now receive a deprecation warning when using them. This warning will not impact any functions that call them (they bypass the stdout and stderr pipes and write directly to your TTY) but it is still recommended that you update any existing code not to use it. The change is very simple, Murex supported expressions as first class primitives, so you can simply drop the = and let command names from your expressions

Features

Features marked as EXPERIMENTAL are provided without assurances of future breaking changes. All other features are considered stable as part of Murex's compatibility commitment.

  • preview: support added for ChatGPT. This feature is disabled by default. (read more) EXPERIMENTAL

  • preview: support added for Makefiles

  • new event: onPreview (read more) EXPERIMENTAL

  • onKeyPress: event completely redesigned (read more) EXPERIMENTAL

  • new builtin: key-code. This builtin allows for easy inspection of what control sequences your terminal emulator is sending to the shell (read more) EXPERIMENTAL

  • events: support added for return values -- allowing events to modify state safely (used in onPreview & onKeyPress)

  • events: smarter error handling

  • runtime: new flags: --integrations, --event-types, --cache-db-enabled, --cache-db-path, --cache-namespaces (read more)

  • core: map added for default mimes per Murex data type (read more)

  • get: support added to default a Content-Type header based on stdin data type (read more)

  • post: support added to default a Content-Type header based on stdin data type (read more)

  • readline: home and end hotkeys added to preview for quick navigation (read more)

  • man-summary now returns a non-zero exit number if no man page is found (read more)

  • datetime: improved error messages (read more)

  • hint text: improved status message for cd (PR #806open in new window)

  • autocomplete: improved autocomplete for go (integrations/go_any.mxopen in new window)

  • optimization: removed various nil checks and pipe dependent checks from release builds (improves performance slightly, albeit in the realm of micro-optimisations)

  • core: new flag: --quiet (issue #797open in new window)

  • core: env pipes without = will now pass the local variable of the same name

  • core: crash handling added. While the shell rarely panics these days, such incidents are not caught. This was intentional so that a stack trace could be produced for debugging. However we are now at the point where catching panics is more valuable than a full stack trace

  • dev tooling: new debug flag, panic, raises an exception to test crashing the shell (read more)

  • dev tooling: added tracing tools for debugging Murex's source code (commit 0a158b0open in new window & commit 6454955open in new window)

  • documentation: lots of new docs written!

  • dev tooling: CI/CD support for latest Go versions

  • dev tooling: new functions added to docgen

Bug Fixes

  • caching: cache.db is now opened on demand. This should allow for better support accessing the cache from multiple Murex sessions in parallel

  • csv: missing flush from CSV marshaller (issue #801open in new window)

  • readline: missing whitespace trimming from recall word (issue #808open in new window)

  • readline: unicode support added for preview -- thus fixing some rendering glitches with non-ASCII characters

  • core: improved garbage collection for forks

  • readline: improved garbage collection for preview

  • readline: include errors in preview

  • profile: openagent for image data type wasn't passing path to image correctly

  • profile: openagent for image data type wasn't autodetecting shell correctly

  • profile: openagent default profile included references to deprecated maths lib

  • safe-commands: td should have been tr

  • safe-commands: let removed due to deprecation of maths lib

  • core: 'executing' state was defined too early. Now happens at last moment before process executes

  • readline: check a builtin is compiled before defaulting to builtin docs in preview

  • readline: pane shouldn't jump to top when loading multiple previews

  • get: fix bug in generated docs

  • get: remove unused parameter from dial timeout

  • core: JSON profiles sometimes weren't getting closed properly (PR #800open in new window)

  • readline: preview now reports if there is nothing to preview

  • readline: out-of-bounds error fixed in preview

  • readline: allow slimmer terminal widths in preview (issue #805open in new window)

  • readline: override MaxTabCompleterRows on short terminals (issue #804open in new window)

  • readline: incorrect clear line ANSI escape sequences

  • core: multiline comments parsed incorrectly inside code blocks

  • core: fixed out-of-range crash when handling specially named scalers

  • autocomplete: incorrectly name scaler for yarn completion was causing it to fail
