09/10/2017, 9:25 PM@simon.vergauwen I mapped the domain on jitpack so the real groupId and artifactId could apply here - s

09/10/2017, 9:50 PMawesome! - v

09/10/2017, 10:14 PMcool. it works! what with annotations? I can add annotation, how to generate? - r
raulraja
09/10/2017, 10:22 PM@vlastachu bear with us while we get some proper docs up for all the modules. For now you can annotate your data class like so..Copy codeimport kategory.optics.lenses @lenses data class A(val b: B, val c: C) - r
raulraja
09/10/2017, 10:22 PMEnsure kapt runs on the source as the lenses are generated at compile time with the annotation processor - v
vlastachu
09/10/2017, 10:22 PMow. kapt - r
raulraja
09/10/2017, 10:22 PMthat will generate lenses for all the properties - r
raulraja
09/10/2017, 10:23 PMAlternatively you can create lenses by hand and @simon.vergauwen can probably offer advice here on how to do that. - v
vlastachu
09/10/2017, 10:26 PMyes, I create already. it works.Copy code
enable kapt. Now somewhere should appear nameLens, right?import kategory.optics.* @lenses data class Child( val name: String ) - s
simon.vergauwen
09/10/2017, 10:33 PMyes it will be generated in
package with a filenamekategory.opticsoptics.kategory.lens.child - s
simon.vergauwen
09/10/2017, 10:34 PMTo access the lenses you can also use the
it should get generated asimport kategory.optics.*childName(): Lens<Child,String> - s
simon.vergauwen
09/10/2017, 10:35 PMMake sure your gradle is set up properly to pickup the generated sources. - v
vlastachu
09/10/2017, 10:44 PMwell, found little bug (sure there is more possible bugs). I named my package:
(yeah not best decision) in generated file was importpackage vlastachu.'fun'Copy codeimport vlastachu.fun.Child - r
raulraja
09/10/2017, 10:54 PM@simon.vergauwen shouldn't lenses be generated in the same user package as where the data class is defined? - v
vlastachu
09/10/2017, 10:55 PMfinally, annotations works. but ide can't see them - r
raulraja
09/10/2017, 10:57 PMIDEA should work with annotations, try opening the file again - r
raulraja
09/10/2017, 10:58 PMalso @vlastachu feel free to also join us in #kategory as these are questions more related to the lib than general FP in Kotlin - r

09/10/2017, 11:52 PMFor those of you looking into Kategory typeclasses, better syntax and implicit discovery without registration is underway https://github.com/kategory/kategory/pull/264😱 1👍 1 - p

pakoito
09/11/2017, 9:10 AM@anstaendig maybe because it’s the infrastracture bits. It’s done so the actual day to day use of typeclasses is transparent for library users. - a

09/11/2017, 9:13 AMPotential to learn a lot☝🏻 - p
pakoito
09/11/2017, 9:14 AMthat’s okay, in the end you only have to learn how to use one API to do sequential and parallel operations 😄 - p
pakoito
09/11/2017, 9:14 AMand it’s as simple as - a

09/11/2017, 9:15 AMBut then my inner urge kicks in that wants to know how stuff works
