# Fission Perl environment
|
|
|
|
This is an environment to execute perl code.
|
|
|
|
It is implemented using the lightweight web application framework
|
|
[Dancer2](https://metacpan.org/pod/Dancer2) and the async I/O webserver
|
|
[Twiggy](https://metacpan.org/pod/Twiggy).
|
|
|
|
Since Twiggy is implemented with [AnyEvent](https://metacpan.org/pod/AnyEvent),
|
|
you can write async code using AnyEvent in your function.
|
|
|
|
## Usage
|
|
|
|
The function you upload is actually a perl package returning a coderef (see the
|
|
example).
|
|
|
|
You can use other packages and add more subs, but only the coderef you returned
|
|
from the package is executed directly.
|
|
|
|
Your main-function gets exactly one argument: the Dancer2 request object. You
|
|
may want to `use Dancer2` to get functions like `send_error`.
|
|
|
|
## Example
|
|
|
|
```perl
|
|
# hello.pm
|
|
return sub {
|
|
return 'Hello, Perl!';
|
|
}
|
|
```
