Customize the interactive script/command runner.
Hilbish is unique, when interactive it first attempts to run input as -Lua and then tries shell script. But if you’re normal, you wouldn’t -really be using Hilbish anyway but you’d also not want this -(or maybe want Lua only in some cases.)
The “runner mode” of Hilbish is customizable via hilbish.runnerMode,
-which determines how Hilbish will run user input. By default, this is
-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)
-end)
-The hilbish.runner interface is an alternative to using hilbish.runnerMode
-and also provides the sh and Lua runner functions that Hilbish itself uses.
-A runner function is expected to return 3 values: the input, exit code, and an error.
-The input return is there incase you need to prompt for more input.
-If you don’t, just return the input passed to the runner function.
-The exit code has to be a number, it will be 0 otherwise and the error can be
-nil to indicate no error.
These are the “low level” functions for the hilbish.runner interface.

-overwrites if the named runner already exists.cmd with a runner. If runnerName isn’t passed,
-the current runner mode is used.
