## Introduction
The runner interface contains functions that allow the user to change
The runner interface contains functions that allow the user to change
how Hilbish interprets interactive input.
Users can add and change the default runner for interactive input to any
language or script of their choosing. A good example is using it to
write command in Fennel.
Runners are functions that evaluate user input. The default runners in
Hilbish can run shell script and Lua code.
A runner is passed the input and has to return a table with these values.
All are not required, only the useful ones the runner needs to return.
(So if there isn't an error, just omit `err`.)
- `exitCode` (number): A numerical code to indicate the exit result.
- `input` (string): The user input. This will be used to add
to the history.
- `err` (string): A string to indicate an interal error for the runner.
It can be set to a few special values for Hilbish to throw the right hooks and have a better looking message:
`[command]: not-found` will throw a command.not-found hook based on what `[command]` is.
`[command]: not-executable` will throw a command.not-executable hook.
- `continue` (boolean): Whether to prompt the user for more input.
Here is a simple example of a fennel runner. It falls back to
shell script if fennel eval has an error.
```lua
local fennel = require 'fennel'
hilbish.runnerMode(function(input)
local ok = pcall(fennel.eval, input)
if ok then
return {
input = input
}
end
return hilbish.runner.sh(input)
end)
```

Hilbish has a pretty good completion system. It has a nice looking
menu, with 2 types of menus: grid (like file completions) or
list.
Completions for commands can be created with the [`hilbish.complete`](../api/hilbish#complete)
function. See the link for how to use it.
To create completions for a command is simple.
The callback will be passed 3 parameters:
- `query` (string): The text that the user is currently trying to complete.
This should be used to match entries.
- `ctx` (string): Contains the entire line. Use this if
more text is needed to be parsed for context.
- `fields` (string): The `ctx` split up by spaces.
In most cases, the completer just uses `fields` to check the amount
and `query` on what to match entries on.
In order to return your results, it has to go within a "completion group."
Then you return a table of completion groups and a prefix. The prefix will
usually just be the `query`.
Hilbish allows one to mix completion menus of different types, so
a grid menu and a list menu can be used and complete and display at the same time.
A completion group is a table with these keys:
- `type` (string): type of completion menu, either `grid` or `list`.
- `items` (table): a list of items.
The requirements of the `items` table is different based on the
`type`. If it is a `grid`, it can simply be a table of strings.
Otherwise if it is a `list` then each entry can
either be a string or a table.
Example:
```lua
local cg = {
items = {
'list item 1',
['--command-flag-here'] = {'this does a thing', '--the-flag-alias'}
},
type = 'list'
}
local cg2 = {
items = {'just', 'a bunch', 'of items', 'here', 'hehe'},
type = 'grid'
}
return {cg, cg2}, prefix
```
Which looks like this:

# Completion Handler
Like most parts of Hilbish, it's made to be extensible and
customizable. The default handler for completions in general can
be overwritten to provide more advanced completions if needed.
This usually doesn't need to be done though, unless you know
what you're doing.
# Completion Handler
By default, it provides 3 things: for the first argument,
The default completion handler provides 3 things:
binaries (with a plain name requested to complete, those in
$PATH), files, or command completions. With the default
completion handler, it will try to run a handler for the
command or fallback to file completions.
$PATH), files, or command completions. It will try to run a handler
for the command or fallback to file completions.
To overwrite it, just assign a function to
`hilbish.completion.handler` like so:
To overwrite it, just assign a function to `hilbish.completion.handler` like so:
```lua
-- line is the entire line as a string
-- pos is the position of the cursor.
function hilbish.completion.handler(line, pos)
-- do things
end
It is passed 2 arguments, the entire line, and the current
cursor position. The functions in the completion interface
take 3 arguments: query, ctx, and fields.
- The `query`, which what the user is currently trying to complete
- `ctx`, being just the entire line
- `fields` being a table of arguments. It's just `ctx` split up,
delimited by spaces.
It's expected to return 2 things: a table of completion groups, and
a prefix. A completion group is defined as a table with 2 keys:
`items` and `type`.
- The `items` field is just a table of items to use for completions.
- The `type` is for the completion menu type, being either `grid` or
`list`.
The prefix is what all the completions start with. It should be empty
if the user doesn't have a query. If the beginning of the completion
item does not match the prefix, it will be replaced and fixed
properly in the line. It is case sensitive.
If you want to overwrite the functionality of the general completion
handler, or make your command completion have files as well
(and filter them), then there is the `files` function, which is
mentioned below.
# Completion Interface
## Functions
- `files(query, ctx, fields)` -> table, prefix: get file completions,
based on the user's query.
- `bins(query, ctx, fields)` -> table, prefix: get binary/executable
completions, based on user query.
- `call(scope, query, ctx, fields)` -> table, prefix: call a completion
handler with `scope`, usually being in the form of `command.<name>`

Hilbish allows you to change how interactive text can be interpreted.
This is mainly due to the fact that the default method Hilbish uses
is that it runs Lua first and then falls back to shell script.
In some cases, someone might want to switch to just shell script to avoid
it while interactive but still have a Lua config, or go full Lua to use
Hilbish as a REPL. This also allows users to add alternative languages like
Fennel as the interactive script runner.
Runner mode can also be used to handle specific kinds of input before
evaluating like normal, which is how [Link.hsh](https://github.com/TorchedSammy/Link.hsh)
handles links.
The "runner mode" of Hilbish is customizable via `hilbish.runnerMode`,

set to `hybrid` which is the previously mentioned behaviour of running Lua
first then going to shell script. If you want the reverse order, you can
set it to `hybridRev` and for isolated modes there is `sh` and `lua`
respectively.
You can also set it to a function, which will be called everytime Hilbish
needs to run interactive input. For example, you can set this to a simple
function to compile and evaluate Fennel, and now you can run Fennel.
You can even mix it with sh to make a hybrid mode with Lua replaced by
Fennel.
An example:
hilbish.runnerMode(function(input)
local ok = pcall(fennel.eval, input)
if ok then
return input, 0, nil
end
return hilbish.runner.sh(input)
