🎀 Changelog

This is the changelog for the Hilbish shell made in Go and Lua.

0.5.1 - 2021-06-16

Added

• Add ~/.config/hilbish as a require path

Changed

• cd hook is only thrown after directory has actually changed

Fixed

• Handle error in commander properly, preventing a panic from Lua

0.5.0 - 2021-06-12

An absolutely massive release. Probably the biggest yet, includes a bunch of fixes and new features and convenient additions to the Lua API.

Added

• -n flag, which checks Lua for syntax errors without running it
• exec(command) function, acts like the exec builtin in sh
  • Example: exec 'awesome' in an .xinitrc file with Hilbish as shebang
• Commands from commander can now return an exit code

commander.register('false', function()
return 1
end)

When false is run, it will have the exit code of 1, this is shorter/easier than throwing the command.exit hook and can work if the functionality of that changes

• Added -c description
• args variable, set when Hilbish runs a Lua script. It is an array that includes the execute path as the first argument
• Lua code can be aliased
• Recursive aliases
  • At the moment this only works for the first argument
• Hilbish can now be used with Hilbiline if compiled to do so (currently only for testing purposes)
• goro(func) runs a function in a goroutine. With channels that gopher-lua also provides, one can do parallelism and concurrency in Lua (but go style).
  • coroutine no those dont exist they dont matter goro is easier
• cd - will change to the previous directory
• hilbish.cwd() gets the current working directory
• timeout(func, time) works exactly like the setTimeout function in JavaScript. It will run func after a period of time in milliseconds.
• interval(func, time) works exactly like the setInterval function in JavaScripit. It will run func every time milliseconds
• hilbish.home is a crossplatform Lua alternative to get the home directory easily.
• commander.deregister(cmdName) de-registers any command defined with commander.

Changed

• Breaking Change: Move _user and _ver to a global hilbish table
  • Accessing username and Hilbish version is now done with hilbish.user and hilbish.ver
• hilbish.run(cmd) runs cmd with Hilbish's sh interpreter. Using this function instead of os.execute ensures that sh syntax works everywhere Hilbish does.
• hilbish.flag(flag) checks if flag has been passed to Hilbish.
• Aliases now work with every command and not only the first one
  • Therefore alias1; alias2 works now
• command.not-found hook
• $SHLVL is now incremented in Hilbish. If not a valid number, it will be changed to 1
• fs.mkdir can now make directories recursively if the 2nd argument is set to true
  • fs.mkdir('path/to/dir', true)
• Hilbish runs a preload.lua file in the current directory first, then falls back to the global preload. Before the order was reversed.
• Check if aliased command is defined in Lua, so registered commanders can be aliased
• Add input to history before alias expansion. Basically, this adds the actual alias to history instead of the aliased command.
• Global preload path, require paths, default config directory and sample config directory can now be changed at compile time to help support other systems.

Fixed

• cd now exits with code 1 instead of the error code if it occurs
• Don't append directory to $PATH with appendPath if its already there
• Continued input is no longer joined with a space unless explicitly wanted
• Hilbish won't try to go interactive if it isn't launched in a TTY (terminal)
• Ctrl+D on a continue prompt with no input no longer causes a panic
• Actually handle the -h/--help option

0.4.0 - 2021-05-01

Added

• Ctrl C in the prompt now cancels/clear input (I've needed this for so long also)
• Made Hilbish act like a login shell on login
  • If Hilbish is the login shell, or the -l/--login flags are used, Hilbish will use an additional ~/.hprofile.lua file, you can use this to set environment variables once on login
• -c has been added to run a single command (this works exactly like being in the prompt would, so Lua works as well)
• -i (also --interactive) has been added to force Hilbish to be an interactive shell in cases where it usually wont be (like with -c)
• Use readline in continue prompt
• Added a mulitline hook that's thrown when in the continue/multiline prompt
• Added appendPath function to append a directory to $PATH
  • ~ will be expanded to $HOME as well
• A utility string.split function is now added
  • string.split(str, delimiter)
• Added a _user variable to easily get current user's name

Changed

• BREAKING Change: Lunacolors has replaced ansikit for formatting colors, which means the format function has been removed from ansikit and moved to Lunacolors.
  • Users must replace ansikit with lunacolors in their config files
• A getopt-like library is now used for command line flag parsing
• cd builtin now supports using environment variables
  • This means you can now cd $NVM_DIR as an example
• Function arguments are now more strictly typed (prompt(nil) wouldnt work now)
• Other general code/style changes

Fixed

• Fix makefile adding Hilbish to /etc/shells on every make install

Since Lunacolors is a submodule, you may just want to completely reclone Hilbish recursively and then update (rerun make install) Or instead of recloning, run git submodule update --init --recursive in Hilbish's git directory

0.3.2 - 2021-04-10

Added

• Add more functions to ansikit module
• Add functions stat and mkdir to fs module
• -C flag to define path to config
• Add require path ~/.local/share/hilbish/libs

Changed

• Continue to new line if output doesnt end with it

Observed:

0.3.1 - 2021-04-06

Fixed

• Fix %u in prompt format being full name and instead make it actually username

0.3.0 - 2021-04-05

Added

• Added a multiprompt function to change the prompt of the multiline/continuation/newline prompt
• _ver variable to get Hilbish's version from Lua

Changed

• BREAKING Change: Removed Bait hooks command.success and command.fail, there is now the single hook command.exit, with a single argument passed which the exit code of the command. Use this to determine if a command has failed or not (failure is code != 0)
• BREAKING Change: The Ansikit function text has been renamed to format.
• fs.cd now throws an exception instead of silently failing, which you should handle with pcall
• Enhancements to the cd command:
  • With no arguments will move to $HOME
  • Now throws a cd hook, with a single hook arg being the arguments to the command
  • Now works for directories with spaces
• Lua input now throws a success hook if it succeeded
• Command history is now saved to ~/.hilbish-history
• Globals defined in Lua that are strings will be defined as an env variable (#16)
• Input ending with \ will now go to a newline
• exit command is now written in Lua

Fixed

• Input is now trimmed
• Internals are slightly cleaned up and codebase split up
• Hilbish will now fall back to a builtin minimal config if the user's config has syntax errors on loading
• Commands defined in Lua now report the error to the user cleanly instead of panicking if it has occured

0.2.0 - 2021-03-31

Added

• Hooks (events) are the new and main thing in v0.2, you can now listen for hooks or cast out (emit) custom ones, via the bait package
• ^^ to refer to the previous command. It's for the lazy hands like me, so I can do something like ENV=VAR ^^
• Way more (more like any) comments in the core code.

Changed

• Prompt has been changed to have printf-like verbs to format. This makes it easier on the user's side to configure, and doesn't require hooks to change it for things like current directory.
• Default prompt's changed and the triangle changes color based on if command failed or not.

0.1.2 - 2021-03-24

Added

• Add Lua input to history

0.1.1 - 2021-03-24

Added

• Go to new line if sh input is incomplete

> for i in {1..5}

This input for example will prompt for more input to complete:

0.1.0 - 2021-03-24

Added

• Tab complete files
• Makefile installation
• sh support

0.0.12 - 2021-03-21

First "stable" release of Hilbish.
