<a href=#aliascmd-orig class=heading-link><i class="fas fa-paperclip"></i></a></h4><p>Sets an alias of <code>cmd</code> to <code>orig</code></p><h4 id=appendpathdir class=heading>appendPath(dir)

|
|
<a href=#completescope-cb class=heading-link><i class="fas fa-paperclip"></i></a></h4><p>Registers a completion handler for <code>scope</code>.
|
|
A <code>scope</code> is currently only expected to be <code>command.<cmd></code>,
|
|
replacing <cmd>with the name of the command (for example <code>command.git</code>).
|
|
<code>cb</code> must be a function that returns a table of “completion groups.”
|
|
Check <code>doc completions</code> for more information.</p><h4 id=cwd---string class=heading>cwd() -> string
|
|
<a href=#cwd---string class=heading-link><i class="fas fa-paperclip"></i></a></h4><p>Returns the current directory of the shell</p><h4 id=execcmd class=heading>exec(cmd)

|
|
<a href=#highlighterline class=heading-link><i class="fas fa-paperclip"></i></a></h4><p>Line highlighter handler. This is mainly for syntax highlighting, but in
|
|
reality could set the input of the prompt to <em>display</em> 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:</p><pre tabindex=0><code>function hilbish.highlighter(line)
|
|
return line:gsub('"%w+"', function(c) return lunacolors.green(c) end)
|
|
end
|
|
</code></pre><p>This code will highlight all double quoted strings in green.</p><h4 id=hinterline-pos class=heading>hinter(line, pos)
|
|
<a href=#hinterline-pos class=heading-link><i class="fas fa-paperclip"></i></a></h4><p>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.</p><h4 id=inputmodemode class=heading>inputMode(mode)

<a href=#inputmodemode class=heading-link><i class="fas fa-paperclip"></i></a></h4><p>Sets the input mode for Hilbish’s line reader.

<a href=#promptstr-typ class=heading-link><i class="fas fa-paperclip"></i></a></h4><p>Changes the shell prompt to <code>str</code>
|
|
There are a few verbs that can be used in the prompt text.
|
|
These will be formatted and replaced with the appropriate values.
|
|
<code>%d</code> - Current working directory
|
|
<code>%u</code> - Name of current user
|
|
<code>%h</code> - Hostname of device</p><h4 id=readprompt---input-string class=heading>read(prompt) -> input (string)
|
|
<a href=#readprompt---input-string class=heading-link><i class="fas fa-paperclip"></i></a></h4><p>Read input from the user, using Hilbish’s line editor/input reader.
|
|
This is a separate instance from the one Hilbish actually uses.
|
|
Returns <code>input</code>, will be nil if ctrl + d is pressed, or an error occurs (which shouldn’t happen)</p><h4 id=runcmd-returnout---exitcode-number-stdout-string-stderr-string class=heading>run(cmd, returnOut) -> exitCode (number), stdout (string), stderr (string)
|
|
<a href=#runcmd-returnout---exitcode-number-stdout-string-stderr-string class=heading-link><i class="fas fa-paperclip"></i></a></h4><p>Runs <code>cmd</code> in Hilbish’s sh interpreter.
|
|
If returnOut is true, the outputs of <code>cmd</code> will be returned as the 2nd and
|
|
3rd values instead of being outputted to the terminal.</p><h4 id=runnermodemode class=heading>runnerMode(mode)
|
|
<a href=#runnermodemode class=heading-link><i class="fas fa-paperclip"></i></a></h4><p>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.</p><h4 id=timeoutcb-time---a-hrefhilbishdocsapihilbishhilbishtimerstimer-styletext-decoration-nonetimera class=heading>timeout(cb, time) -> <a href=/Hilbish/docs/api/hilbish/hilbish.timers/#timer style=text-decoration:none>Timer</a>
