v4.2

Murex usage has raised considerably in recent weeks. This release addresses a number of feature requests and bugs raised on Github.

Breaking Changes

none

Features

• new flag in foreach: --step <int>. This allows the foreach to jump indexes at a time. When used, all the lines jumped are merged into a JSON array and that is passed to the foreach nested code block
• new alias builtin => fexec builtin. This was added to bring more familiarity to those coming from Bash et al (#608)
• on Darwin, Homebrew defaults are imported, just like you’d expect them to be from any other shell
• new hotkeys (#611) (#613):
  1. ctrl+a: jump to beginning of line
  2. ctrl+e: jump to end of line
  3. alt+f: jump forwards a word at a time
  4. alt+b: jump backwards a word at a time
  5. ctrl+k: clear line after cursor position
  6. ctrl+l: clear entire screen
  7. ctrl+g: same as esc
• open builtin should fallback to system default if type unknown (#620)
• pre-prompt-func added to config. Block runs before the interactive prompt is displayed
• post-prompt-func added to config. Block runs after the interactive prompt has been exited but before any command lines have been executed
• auto-cd option added to config: config: set shell auto-cd true. This allows you to traverse directories without having to prefix cd. By default it is disabled
• Meta values added to foreach, formap, and while. Meta values are a $. variable that holds meta-information about the running block, such as the number of iterations in a loop
• command alias for exec (for familiarity with Bash)
• builtin alias for fexec builtin (for familiarity with Bash)

Bug Fixes

• brace encapsulated variables, eg $(foobar), now autocomplete as expected
• improvements to inlining images in iTerm2 when shell running on top of tmux. It still doesn’t work reliably but this is an issue with tmux rather than Murex
• method forwards exceptions rather than errors. This behaviour has been changed to surface issues as errors
• profile_preload.mx added to profile defaults. This will be loaded before any of the OS-specific profiles
• missing rune length check causing the shell to panic (#617)
• fixed deadlock in flag parsing
• zero length string title bars should be ignored (#614)
• minor improvements to documentation
