Plack-extending micro framework

[Stefan Geneshky]

Hello everyone,

I got Miyagawa's OK to post this, and I hope it doesn't come off as spam, since it's intended to be more of a reach towards the general Perl/Plack community.

I began working on this a while back, when I needed a Plack-centric web framework. Over time it got pretty big, and I thought I'd post it on CPAN, hoping that it would be useful to other people too:

https://metacpan.org/module/Kelp

It's a micro web framework that wraps around Plack, and uses its helper modules for its internals. In other words, Kelp is a pure-Plack framework. 

I'd be happy to answer any questions, and I hope the community finds this useful.

Regards,

Stefan

Looks nice. Thanks for publishing it!

Nice framework.

 

It was hard to install it though because cpanm gave the error:
"! The distribution doesn't have a proper Makefile.PL/Build.PL"

 

And trying to install it manually I found that it needs Config::Hash which can't be installed with cpanm either.

 

After installing Config::Hash manually I found that Kelp has a test that gave an error:

 

D:\Kelp-0.216\Kelp-0.216>prove t/module.t
t/module.t .. Can't locate Kelp/Base.pm in @INC (@INC contains: D:/usr/site/lib/
MSWin32-x86-multi-thread D:/usr/site/lib D:/usr/lib .) at t/module.t line 2.
BEGIN failed--compilation aborted at t/module.t line 2.
t/module.t .. Dubious, test returned 2 (wstat 512, 0x200)
No subtests run
Test Summary Report
-------------------
t/module.t (Wstat: 512 Tests: 0 Failed: 0)
Non-zero exit status: 2
Parse errors: No plan found in TAP output
Files=1, Tests=0,  0 wallclock secs ( 0.00 usr +  0.02 sys =  0.02 CPU)
Result: FAIL

 

I installed it however, and I've seen that as expected the test app needs a little less memory than the test apps for Dancer2, Mojolicious or Catalyst.

In this kind of manual testing situation, I believe you need the -l flag
for prove, which causes it to consider modules located in ./lib

What does this report?

prove -lv t/module.t

Octavian,

Thank for catching this problem. One of the .t files required Config::Hash and that was not properly written in the Makefile.

I removed that dependency and released Kelp 0.217 on CPAN, which should install with no errors.

Keep in mind that Kelp may not be fully Windows compliant. I can not guarantee that it will fully work under non *nix operating systems.

It's a good sign, however, that you were able to get it going.

I have not run any comparison test and benchmarks (I intend to do that this weekend), but I suspect that Kelp will rank significantly higher than the rest in both performance and memory use.

In order to not hijack Plack's group, I have created a new one specifically for Kelp:

https://groups.google.com/forum/?fromgroups=#!forum/perl-kelp

Please feel free to post any issues, questions or comments there.

Regards,

Stefan
