2022-12-15 04:01:14 +00:00
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
2023-12-26 03:08:46 +00:00
write command in Fennel.< / p > < p > Runners are functions that evaluate user input. The default runners in
Hilbish can run shell script and Lua code.< / p > < p > 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.
2024-08-31 20:51:15 +00:00
(So if there isn’ t an error, just omit < code > err< / code > .)< / p > < ul > < li > < code > exitCode< / code > (number): Exit code of the command< / li > < li > < code > input< / code > (string): The text input of the user. This is used by Hilbish to append extra input, in case
more is requested.< / li > < li > < code > err< / code > (string): A string that represents an error from the runner.
This should only be set when, for example, there is a syntax error.
It can be set to a few special values for Hilbish to throw the right
hooks and have a better looking message.< ul > < li > < code > \< command>: not-found< / code > will throw a < code > command.not-found< / code > hook
based on what < code > \< command>< / code > is.< / li > < li > < code > \< command>: not-executable< / code > will throw a < code > command.not-executable< / code > hook.< / li > < / ul > < / li > < li > < code > continue< / code > (boolean): Whether Hilbish should prompt the user for no input< / li > < li > < code > newline< / code > (boolean): Whether a newline should be added at the end of < code > input< / code > .< / li > < / ul > < p > Here is a simple example of a fennel runner.
