`cb` must be a function that returns a table of "completion groups."

|
</h4>
|
|
|
|
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.

</h4>
|
|
|
|
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.
