v5.0.9200

[lmorg]

Breaking Changes

• unquoted parameters that are formatted like [alpha, numeric, underscore]\(...\) will be parsed as a function rather than a string. eg command foo(bar baz) where foo will be treated as a subshell function with bar baz as its parameters
• brace quotes without a leading % will be first parsed as an expression. eg %(valid string) vs (valid expression)

Deprecation Warnings

These are changes to Murex defaults, however you shouldn't expect any breaking changes to Murex's behaviour:

• $ARGV now preferred instead of $ARGS ($ARGS will remain supported for now)
• command: parameters ... style syntax has been deprecated in favour of the more traditional command parameters ... (without a colon) syntax.

Features

• new website!!

• commands can now be inlined in expressions, eg foobar = uptime() (issue 676)

• commands can also be inlined into statements too, eg echo uptime() (issue 676)

• new event onSignalReceived for catching OS signals

• new builtin signal for sending OS signals

• new builtins which (issue 609)

• new builtin type (issue 609)

• cd defaults to ~ if now parameters are passed (issue 672)

• cd - changes to previous directory (issue 672)

• $SELF.Interactive value to detect if scope is running in an interactive shell (issue 685)

• $COLUMNS reserved variable to output width of terminal

• $MUREX_ARGV reserved variable to output command line parameters of Murex shell (not to be confused with the parameters of the running function, eg $ARGV)

• csv data type and select builtin now support converting maps (eg JSON objects) into tables (issue 689)

• murex-doc / help can now display a greater number of documents when offline

• improved man page parsing

• improved man page displays in preview

• alias now stores FileRef metadata (issue 124)

• packages can now be removed via murex-package remove (issue 687)

• a package creation wizard has been added via murex-package new

• another new flag for murex-package: git. Which allows you to run git commands on a package even when you're not in that package's working directory

• version constraints added to Murex packages (docs to follow)

• readline: up and down arrows on a partial command line will cycle through history of only lines that contain your partial command line

• readline: new hotkey, ctrl+z while readline is open will undo the previous key strokes

• EXPERIMENTAL: logical operators added to expressions: || and && (issue 708)

• EXPERIMENTAL: new command modifier <pid:VARNAME> sets $VARNAME with a commands process ID, if an external process (currently doesn't support local variables)

• EXPERIMENTAL: new command modifier <fid:VARNAME> sets $VARNAME with the Murex function ID of the command (currently doesn't support local variables)

• EXPERIMENTAL: new assignment operator :=, assigns a value but retains the former data type, thus converting the value when required (ideally I'd have preferred this as default option but it ran the risk of some serious and unexpected breaking changes to the behaviour of some existing shell scripts)

• EXPERIMENTAL: Various builtins that require variable names now support $ sigils, eg foreach $var { ... } works as well as foreach var { ... }

• EXPERIMENTAL: new variable group $MOD, like $GLOBAL but scoped to the module level

• EXPERIMENTAL: official support added for a pure Go library for sqlite3 -- thus saving individuals from having to install gcc as well as go compilers. The reduced cgo footprint has already reduced file sizes by a 3rd

Bug Fixes

• homebrew environment set on Intel macOS systems (previous only worked on ARM)
• config functions (eg hint-text-func) now execute with the FileRef of the setter. Meaning they can call privates correctly
• scalars fail expression pre-parser (issue 674)
• readline: prompt can now span multiple lines (issue 612)
• floating point numbers were not loosely compared correctly in expressions
• readline: delay timer hint text should disappear when completed
• $PWDHIST was corrupting upon first update
• fixed bug with git-commit man page parsing, which caused the parser to hang and ramp up CPU usage on git autocompletions
• fixed parsing of nested quotes inside curly braces (issue 697)
• don't carry non-zero exit numbers forward if unit test successful
• fixed instances where FileRef either wasn't being set, wasn't being set correctly, or was missing a timestamp (issue 696)
• printf dependency removed from aliases function -- this means aliases now works on Windows too
• || and && now parse correctly in expressions

Special Thanks

Special thank yous for this release goes to the following contributors:

• orefalo for building the new website (which is now small task!), documentation fixes, and general support
• tiymat for the high quality bug reports and beta testing
• All the downstream package maintainers, who publish Murex to their preferred operating systems/package managers thus making it easier for a wider audience to install and update Murex

You rock!

Congrats - will relay the announcement on the few social networks I participate.

Are you posting on reddit, hackernews... etc?

I'm not on Reddit but have posted on HN in the past. I wasn't going to submit this release personally though I'm more than happy for you to spread the word :)
