The quickest way to try out Phel is to run our REPL Docker container.
docker run -it --rm phellang/replKudos to @jenshaase -> https://phel-lang.org/#try-phel
Specifically the performance mentioned when loading your blog
To me it looks like you've resolved it with the compile ability
I've managed to get the compile command to work and my TTFB went from cca. 1.06s down to 140ms!

I came across this https://openswoole.com/ and thought it would be an interesting project to use that with phel
I'm using this repo for reference https://github.com/mabasic/mariobasic-n7 but I can't figure out how to handle the compiling
I see
out-dir set in phel-config.php and composer.json references running a local php webserver, and public/index.php contains code that references the compiled phel code
btw, this is a lot of fun
probably helped if I read the man page
phel compile
ah maybe Mario does that outside of the repo which is why i couldnt find it

I created a ticket to explain all the command in a separate chapter on the website: phel-lang/phel-lang.org#34
So I got something working https://github.com/adam-stokes/phel-framework-x, the one thing im trying to figure out is when i do
phel compile it'll compile the phel language into dist but my custom code doesn't seem to be written into dist

Im loving being able to use the huge php ecosystem with phel
My goal is to have a website created using RoadRunner application server, framework-x.org (which uses reactphp underneath)
If using an application server like RoadRunner that doesn't spin up php on every request could I get similar performance with https://github.com/adam-stokes/phel-framework-x/blob/main/public/index.php#L14-L16?
So this line https://github.com/adam-stokes/phel-framework-x/blob/main/src/boot.phel#L9 is being executed by
phel compile, is there a recommended way to get around this?
Use the
*compile-mode* variable as a condition: https://phel-lang.org/documentation/api/#compile-mode
diff --git a/src/boot.phel b/src/boot.phel
index 529c0c5..32facf4 100644
--- a/src/boot.phel
+++ b/src/boot.phel
@@ -6,4 +6,5 @@
(php/-> site-app (get "/" (fn [] (php/:: Response (plaintext "Hello There")))))
-(php/-> site-app (run))
\ No newline at end of file
+(when-not *compile-mode*
+ (php/-> site-app (run)))
Works great!
@mabasic: Maybe you know, I was looking at RoadRunner as my app server, do you think I need to compile still?

Yep that's the same php file im using :)
This is what im currently working on https://github.com/adam-stokes/phel-framework-x

good call on that, i had 8955 __phel tmp files
I really like this approach, I can be productive and then start bringing in more of the functional aspects of the language
In some of the php docs i've come across
use in closures, return new React\Promise\Promise(function ($resolve, $reject) use ($body) how would I represent that in phel?
use is not required in phel. You can just use fn and reference variables outside of the scope of the function.
Probably a stupid question and my ignorance of functional programming, but for things like creating a controller https://symfony.com/doc/current/controller.html#a-basic-controller, since there is no class creation in phel is this possible still?
Or inheriting an abstractcontroller https://symfony.com/doc/current/controller.html#the-base-controller-class-services
hmm symphony uses type-hints too for declaring services to be injected
You can not create real classes in Phel. However, structs are classes and you can add methods to them by using interfaces: https://phel-lang.org/documentation/interfaces/
The struct
my-type-with-two-interfaces is a PHP class that implements the interfaces MyFirstInterface and MySecondInterface.
Ah ok, I did read about that in your docs, I'll give that a go
Hey everybody, I just publish a new repository in the phel-lang organization. This repository contains a router library. It is still work in progress and requires some changes of Phel that have not been released yet but are already in master. Feel free to check it out: https://github.com/phel-lang/router

I created some good first issues for Phel, in case you are looking for a testing challenge/opportunity in a new project, like a testing kata. They are about adding unit tests for some
SpecialForm that I did miss a year ago when I was working on them, and I learned a lot by doing this. I found this now, so instead of doing them myself, I think it's good to let others try themselves if someone wants to contribute doing anything but they don't know where to start. These are like "exclusives testing katas" with a lot of learning opportunities :)
