Introduction
The Hilbish module includes the core API, containing interfaces and functions which directly relate to shell functionality.
Functions
| alias(cmd, orig) | Sets an alias of cmd to orig |
| appendPath(dir) | Appends dir to $PATH |
| complete(scope, cb) | Registers a completion handler for scope. |
| cwd() -> string | Returns the current directory of the shell |
| exec(cmd) | Replaces running hilbish with cmd |
| goro(fn) | Puts fn in a goroutine |
| highlighter(line) | Line highlighter handler. This is mainly for syntax highlighting, but in |
| hinter(line, pos) | The command line hint handler. It gets called on every key insert to |
| inputMode(mode) | Sets the input mode for Hilbish's line reader. Accepts either emacs or vim |
| interval(cb, time) -> @Timer | Runs the cb function every time milliseconds. |
| multiprompt(str) | Changes the continued line prompt to str |
| prependPath(dir) | Prepends dir to $PATH |
| prompt(str, typ) | Changes the shell prompt to str |
| read(prompt) -> input (string) | Read input from the user, using Hilbish's line editor/input reader. |
| run(cmd, returnOut) -> exitCode (number), stdout (string), stderr (string) | Runs cmd in Hilbish's sh interpreter. |
| runnerMode(mode) | Sets the execution/runner mode for interactive Hilbish. This determines whether |
| timeout(cb, time) -> @Timer | Runs the cb function after time in milliseconds. |
| which(name) -> string | Checks if name is a valid command. |
Static module fields
| ver | The version of Hilbish |
| goVersion | The version of Go that Hilbish was compiled with |
| user | Username of the user |
| host | Hostname of the machine |
| dataDir | Directory for Hilbish data files, including the docs and default modules |
| interactive | Is Hilbish in an interactive shell? |
| login | Is Hilbish the login shell? |
| vimMode | Current Vim input mode of Hilbish (will be nil if not in Vim input mode) |
| exitCode | Exit code of the last executed command |
hilbish.complete(scope, cb)
Registers a completion handler for scope.
A scope is currently only expected to be command.<cmd>,
replacing with the name of the command (for example command.git).
cb must be a function that returns a table of "completion groups."
Check doc completions for more information.
Parameters
This function has no parameters.
hilbish.cwd() -> string
Returns the current directory of the shell
Parameters
This function has no parameters.
hilbish.highlighter(line)
Line highlighter handler. This is mainly for syntax highlighting, but in
reality could set the input of the prompt to display anything. The
callback is passed the current line and is expected to return a line that
will be used as the input display.
Note that to set a highlighter, one has to override this function.
Example:
function hilbish.highlighter(line)
return line:gsub('"%w+"', function(c) return lunacolors.green(c) end)
end
This code will highlight all double quoted strings in green.
Parameters
This function has no parameters.
hilbish.hinter(line, pos)
The command line hint handler. It gets called on every key insert to
determine what text to use as an inline hint. It is passed the current
line and cursor position. It is expected to return a string which is used
as the text for the hint. This is by default a shim. To set hints,
override this function with your custom handler.
Parameters
This function has no parameters.
hilbish.inputMode(mode)
Sets the input mode for Hilbish's line reader. Accepts either emacs or vim
Parameters
This function has no parameters.
hilbish.interval(cb, time) -> Timer
Runs the cb function every time milliseconds.
This creates a timer that starts immediately.
Parameters
This function has no parameters.
hilbish.multiprompt(str)
Changes the continued line prompt to str
Parameters
This function has no parameters.
hilbish.prompt(str, typ)
Changes the shell prompt to str
There are a few verbs that can be used in the prompt text.
These will be formatted and replaced with the appropriate values.
%d - Current working directory
%u - Name of current user
%h - Hostname of device
Parameters
This function has no parameters.
hilbish.read(prompt) -> input (string)
Read input from the user, using Hilbish's line editor/input reader.
This is a separate instance from the one Hilbish actually uses.
Returns input, will be nil if ctrl + d is pressed, or an error occurs (which shouldn't happen)
Parameters
This function has no parameters.
hilbish.run(cmd, returnOut) -> exitCode (number), stdout (string), stderr (string)
Runs cmd in Hilbish's sh interpreter.
If returnOut is true, the outputs of cmd will be returned as the 2nd and
3rd values instead of being outputted to the terminal.
Parameters
This function has no parameters.
hilbish.runnerMode(mode)
Sets the execution/runner mode for interactive Hilbish. This determines whether
Hilbish wll try to run input as Lua and/or sh or only do one of either.
Accepted values for mode are hybrid (the default), hybridRev (sh first then Lua),
sh, and lua. It also accepts a function, to which if it is passed one
will call it to execute user input instead.
Parameters
This function has no parameters.
hilbish.timeout(cb, time) -> Timer
Runs the cb function after time in milliseconds.
This creates a timer that starts immediately.
Parameters
This function has no parameters.
hilbish.which(name) -> string
Checks if name is a valid command.
Will return the path of the binary, or a basename if it's a commander.
Parameters
This function has no parameters.
Types
Sink
A sink is a structure that has input and/or output to/from a desination.
Methods
autoFlush(auto)
Sets/toggles the option of automatically flushing output. A call with no argument will toggle the value.
flush()
Flush writes all buffered input to the sink.
read() -> string
Reads a liine of input from the sink.
readAll() -> string
Reads all input from the sink.
write(str)
Writes data to a sink.
writeln(str)
Writes data to a sink with a newline at the end.
