My perl is Rakudo version 2017.09-355-g27131ed8d built on MoarVM version 2017.09.1-575-gd4e230a6. Doing the same process works fine on Linux, though the Linux server is running an older version of Rakudo.
The stub for zmq is generating a META6 with dependency of Cro::ZMQ that seems to not exist. Probably it should be Cro::ZeroMQ

This should produce a summary output of the services that exist, and their basic information: ID, name, and a list of the endpoints. Something like (with stuff in square brackets to be substituted in):
[id] ([Name])
[path]
🔌 Endpoint [id] ([Name])
Host environment variable: [host-env]
Port environment variable: [port-env]
[id] ([Name])
[path]
🔌 Endpoint [id] ([Name])
Host environment variable: [host-env]
Port environment variable: [port-env]
I'd try bold on the top line with id/name, and then grey or similar for the path to deemphasize it a bit. Can show it relative to the current directory, to keep things short/neat.
This example consumes too much RAM ( without freeing it ) every request and sometimes segfaults.
With MVM_SPESH_DISABLE=1 works fine

Thank you for addressing #4 quickly; however, the published example does not work:
Type check failed in binding to parameter '$application'; expected Cro::Transform but got Bool (Bool::True)
Since the example now defines the routes in a variable called $application, the constructor should now read:
:host<localhost>, :port<10000>, :application($application);
$ cro link add my-http-service http-test-2 https
use Cro::HTTP::Client
my $client = Cro::HTTP::Client.new:
base-uri => "http://%*ENV<HTTP_TEST___HOST>:%*ENV<HTTP_TEST___PORT>/";
I think I'd probably put a line between the use and the rest of the code, but then not indent the code.
Created two services and wanted to try the .cro.yml integration.
dice-bag:
---
name: dice-bag
cro: 1
id: dice-bag
env: []
links: []
entrypoint: service.p6
endpoints:
- id: http
name: HTTP (Insecure)
protocol: http
host-env: DICE_BAG_HOST
port-env: DICE_BAG_PORT
...
monster
---
name: monster
cro: 1
id: monster
env: []
links:
- service: dice-bag
endpoint: http
host-env: DICE_BAG_HOST
port-env: DICE_BAG_PORT
entrypoint: service.p6
endpoints:
- id: http
name: HTTP (Insecure)
protocol: http
host-env: MONSTER_HOST
port-env: MONSTER_PORT
...
Both services live within a parent rpg folder. (It's where my brain goes). Doing cro run in this folder I get :
cro run
▶ Starting dice-bag (dice-bag)
🔌 Endpoint HTTP (Insecure) will be at http://localhost:20000/
▶ Starting monster (monster)
🔌 Endpoint HTTP (Insecure) will be at http://localhost:20000/
📓 monster Listening at http://localhost:20000
⚠ dice-bag address already in use
📓 dice-bag Listening at http://localhost:20000
Looking at it I think it's a logic issue in lib/Cro/Tools/Runner.pm6 in assign-ports. If I'm reading it correctly it attempts to connect to localhost on port 20000. If that manages to connect it increments the count and tries again (up to 60000). If it fails it assumes the port is free and returns the number. But it's not incrementing it in this case. As it's not starting the service the port is being assigned to the next service gets the same port and so on.
I'll look at doing a PR fix for it later but I've got plans for tonight.
I have had good success with the Cro Router and Server, but Cro::HTTP::Client gives me grief. Any request I have tried running results in a promise that is neither kept nor broken. e.g.
my $resp = await Cro::HTTP::Client.get('https://www.perl6.org/');
I am running Cro::Core:ver('0.7') with Rakudo 2017.08-59-g0bc1c8774 on Debian 9 in an EC2 instance.
I can ping the external site just fine from the command line.
I suppose that there may be something blocking rakudo from accessing the network, but the eternal hanging and no hint as to what is wrong seems to be a bad behavior.
Otherwise, this is a very neat project. Thank you!
This should be documented in Cro::HTTP::Request.
If you cro stub an HTTPS service using cro 0.7.1, the service.p6 file includes the line:
certificate-file => %*ENV<{$env-name}_TLS_CERT>
(Note that $env-name did not get properly interpolated into the generated code.)
Due to the entry in your Cro modules for the perl 6 ecosystem (/path/to/master/branch), any travis build gets the latest commit and any test failures (which are happening now). I have changed one of my modules to track a stable branch (named release) and do dev on the master branch. I have modified my .travis.yml file to test both branches. I have modified the Perl 6 ecosystem entry to track the release branch (/path/to/release/branch). That seems to work well for me.
Due to the probable wide use of your CRO services, I think your customers would be better served.
I see that you're adding some middlewares to Cro. Are there any plans for something like PSGI/Plack for Cro/Perl6, so that we can avoid the Web-Framework-Trap (c.f. Catalyst, Dancer, Mojo all implementing lot of in theory generic stuff (like Token/Session Handling, ...)) ?
I haven't tried cro (yet), so I'm not sure if cro is more like a web framework (Mojo/Dancer), or more a generic app framework that happens to work good with web, or an abstraction layer / toolkit I can use to build my own web apps (that will also include a significant non-web part (cronjobs, daemons, import/export scripts)
This questions is probably not an 'issue', but afaik there is no mailinglist?
Greetings,
domm
See https://irclog.perlgeek.de/cro/2017-11-26#i_15497139 for more details.
Essentially, recursive directory watching is generally useful, and finicky to get right, so this sub should be pulled out of the class and made available generally (or even moved into the Perl 6 setting, with Cro-specific bits abstracted out).
Is there an option, or planned option, to exclude directories from the cro run / cro trace file monitoring? For example, it scans node_modules and ,precomp. This slows down startup and when using dynamic require causes a cro service restart.
There is a rakudo ticket with more details, but I think it's a good idea to keep another ticket here so that we can discuss cro-specific things. Also, this ticket may need to be moved to another cro repo.

The stub for zmq is generating a Dockerfile that uses a base image that doesn’t have the libzmq installed
Because SSL up to version 3.0 is already deprecated by RFC7568 I'd suggest renaming all classes to TLS to reflect that it's new code which supports currently security standards.
I'd supply ;-) a pull-request if you want.
Provide an example to show how to get at an uploaded file.
This should give an overview of all of the links. I'd list them grouped by the service they originate from.
If a service name is provided, it should show two groups of links: links from that service, and then links to that service, if any.
https://cro.services/docs/approach#Composition mentions reply, but it throws an error, as it has to be transformer instead.
Hi All,
I tried to follow the Getting started with Cro guide. The install was fine (other than #75 ) and the hello.p6 example produced the expected result. On the other hand, cro stub http hello hello failed because cro is under
/home/david/.rakudobrew/moar-master/install/share/perl6/site/bin
I would assume cro should, by default, reside under a handy place similar to zef which is at
/home/david/.rakudobrew/bin/
So should I manually add the needful to PATH or is there any good practice to deal with that under rakudobrew?
Thanks in advance for the help.

In this page, I found the method $resp.body-blob or $resp.body-text, but couldn't find the method $resp.body.
I think some of the users generally use the method $resp.body rather than the former two methods, since this example sets JSON parser when initializing a client.
Can a route pass a hash back in a response? If so, the Cro::HTTP[S]::Server could emulate a CGI server by returning the standard CGI [with TLS extensions] %*ENV hash with known values for testing.

If writing a client for a JSON API, it may become tedious to set the content type on every request.
After copy/pasting example I didn't noticed that Accept => 'application/json' header is missing so server was returning text/html back. We should at least extend section with header => { Accept => ... or even introduce Cro::HTTP::Client.new: accept => ... as we have content-type already. @jnthn, what do you think? Thx.
I may be doing this wrong, but I tried using cro stub to get something running, and cro run then fails, in two different ways:

The documentation for cro stub templates should include at least one example of extending an existing template. For example, the http template could be extended to set up .gitignore and the extra config files needed for webpack, npm, etc. to make a template that more completely stubs out a React/Redux SPA like the big tutorial page builds.
Dynamic variables get lost inside of route HTTP method (get, post, etc.) routines:
use Cro::HTTP::Router;
use Cro::HTTP::Server;
my $*dyn = 'I am dynamic';
my $application = route {
say $*dyn; # works
{
say $*dyn; # works
}
say -> {
$*dyn; # works
}();
get -> {
content 'text/html', "{$*dyn}"; # Dynamic variable $*dyn not found
}
}
my Cro::Service $hello-service = Cro::HTTP::Server.new(
:host('localhost'), :port(8888), :$application
);
$hello-service.start;
react whenever signal(SIGINT) {
$hello-service.stop;
exit;
}I don’t see that the server provides CGI environment variables. Are they planned or would a PR for them be considered?
I’m looking at using the cro services to test my CGI module—so far it’s working great! I haven’t yet figured out how to add new code inside a route handler but I’m sure there’s a way.
Installed the new version 0.7.4 and created a test project with cro stub.
Works fine. However, starting the app with "cro run" always fails with:
~/repos/tmp/testApp % cro run
An operation first awaited:

First I encountered that with perl6 2017.10. So I installed 2018.01. Problem still exists.
Starting the service directly works flawlessly.
Hi all, just started tinkering with cro and wanted to make a note about how I got it installed on Debian sid. I am using moar 2017.09, zef v0.1.30.
Debian package:
libssl1.0-devThe zef install --/test cro required installing specific versions of:
I installed those by cloning their respective repos and checkout out the required version, and installing.
Is there a simpler way to handle the Perl 6 modules versions and get a successful install only using zef install --/test cro?

Failure is irregular though it passes in about 1 time out of 5-7 attempts.
In the "Set up your routes, and serve them" example on http://mi.cro.services/, the $app variable is created, but not referenced after that. It should probably be passed to the Cro::HTTP::Server.new constructor:
:host<localhost>, :port<10000>, :application($app);
At least, doing this allowed the example to work OK on Windows 10.
In the "Set up your routes, and serve them" example on http://mi.cro.services/ there's:
react whenever signal(SITINT) { $hello.stop; exit; }
That should probably be SIGINT
In "http://cro.services/docs/reference/cro-http-router" there is a
section named "Accessing the Cro::HTTP::Request instance" with this example:
my $app = route {
get -> {
say "Request headers:";
for request.headers {
say "{.name}: {.value}";
}
}
}
When I try to use it I get the following exception:
Request headers:
Host: localhost
Connection: close
Cannot unbox a type object (Cro::HTTP::Response::StatusCode) to int.
