Module hilbish

the core Hilbish API

Introduction

The Hilbish module includes the core API, containing interfaces and functions which directly relate to shell functionality.

Interface 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: xit code of the last executed command

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. 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.

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 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.

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.

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. This creates a timer that starts immediately.

multiprompt(str)

Changes the continued line prompt to str

prependPath(dir)

Prepends dir to $PATH

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

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)

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.

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.

timeout(cb, time) -> Timer

Runs the cb function after time in milliseconds. This creates a timer that starts immediately.

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.

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.
