I know is possible to generate the swagger json from a Scalatra app.(it's clear on the documentation)

Hi,
is there any schedular we can incorporate into scalatra to execute periodically?

Hi guys! I have some warnings during development.
To reproduce:

  • Basic project setup with sbt new scalatra/scalatra.g8 and all defaults;
  • Add JettyLauncher.scala as described in Standalone deployment + adjust build.sbt.

Now when I run in sbt ~Jetty/start console logs ≈ 1100 lines of warnings with similar content as: 

WARN:oeja.AnnotationParser:qtp1427810650-12: javax.servlet.AsyncEvent scanned from multiple locations: jar:file:///Users/emris/scala/sanga/target/webapp/WEB-INF/lib/javax.servlet-api-3.1.0.jar!/javax/servlet/AsyncEvent.class, jar:file:///Users/emris/Library/Caches/Coursier/v1/https/repo1.maven.org/maven2/org/eclipse/jetty/jetty-runner/9.4.29.v20200521/jetty-runner-9.4.29.v20200521.jar!/javax/servlet/AsyncEvent.class

Do I miss some configuration option to fix these conflicts?

I can reproduce this, though most of the warning messages refer to the org.eclipse.jetty.xml package. I'm using Jetty 10.0.6 but "Jetty / start" is, as in your case, pulling in a ton of Jetty 9.x jars from the Coursier cache. Starting the app with the sbt "run" command works fine which is why I hadn't noticed this before. Deleting the cache doesn't help - the next time I start sbt it pulls down a ton of old jars again and "start" yields the same list of warnings.

My project directory is polluted from experimentation with Idea and VSCode/metals (finally decided on Idea) and I think that metals has mucked things up with its insistence on installing bloop. When I nuke the Coursier cache and restart sbt, a lot of what gets pulled down again are libs for scala 2.12 whereas my project is "scalaVersion := "2.13.6". I have not studied the architecture of sbt (yeah, I really should) but since "sbt run" is happy and "sbt Jetty/start" isn't, I suspect the difference (and problem) is related to where - what jvm instance - the app is being run, and the differing classpaths of each. Have you been playing with Metals in your project by any chance?

Sounds like the issue is related to xsbt-web-plugin that provides ~jetty/start functionality. How does it work if you run sbt ~jetty/start in a fresh Scalatra project created by sbt new scalatra/scalatra.g8?

Just upgraded to 2.8.2 and find out that Scalate has been deprecated. Can someone point to some of the background for this? Sad to say that I'm disappointed in this, as it means I'll be stuck at some point. Twirl doesn't really seem like a workable alternative for those of us with Jade/Pug codebases.
Naoki Takezoe
@takezoe
@nilskp Scalate heavily depends on Scala compiler internally and it doesn't seem to be going to support Scala 3 (scalate/scalate#253). Deprecating Scalate is preparation for supporting Scala 3 in Scalatra.

Hello, I am learning scalatra. I am familiar with cake pattern. I have implemented repository using the cake pattern. But I am running into 1. design issues about mixing RepositoryComponent into ScalatraServlet. 2. How is the cake pattern applicable to scalatra servlets? Any references will help.

Hi we're facing a very strange issue when trying to enable CORS, when the header "Access-Control-Request-Method: POST" is set it is not matching our options route to augment the response header for allow-access-control-origin. This header is automatically added by most browser and when trying via postman/curl without this header it is matching our route. Any idea what i'm missing?

@jnatten
We've been using enumeratum for enums (mostly because they allow exhaustive pattern matching checks), is there a way to get scalatra-swagger to work with them?
I see there is some work here with macros, but the @ApiModel from scalatra doesn't have the same fields as the one from io.swagger so i can't find a way to get this to work
Naoki Takezoe
@takezoe
Yeah, Twirl doesn't support Scala3 yet.
Naoki Takezoe
@takezoe
Just adding sbt plugin to your project and enabling it should be enough as described in https://github.com/playframework/twirl. You can put template files under src/main/twirl. Template files will be compiled to Scala methods so you can simply call them from your Scala code.
Naoki Takezoe
@takezoe
Ah, it might be possible to compile Twirl template in Scala2 project and use compiled templates from Scala3 project as a library.
Twirl compiler depends on Scala2 compiler so sbt plugin wouldn't work in Scala3 project anyway.
By the way, why did you ask about Twirl here in a gitter room for Scalatra? I'm just curious...

@Paul-Folbrecht
Oh boy. I had several gitter tabs open and posted in the wrong one. Apologies! I will delete.

@takezoe
No worries! You didn't need to delete your messages :-)

Hi, I set a Content-Type header like "text/cvs;charset=utf-8" but looks Scalatra is trying to guess the charset and for whatever reason the header reaches the client like "text/cvs;charset=GB18030". How can I indicate Scalatra to resopect the charset in the header? (scalatra 2.8.2)
Naoki Takezoe
@takezoe
@bcoromina Could you show your actual code that sets Content-Type?
bcoromina
@bcoromina
val contentTypeHeader: GenericHeader = HttpHeader.ContentType("text/cvs;charset=utf-8")
ActionResult(HttpStatus.SC_OK, file.content, contentTypeHeader.toMap)
I think when Scalatra renders the ActionResult something is out of control
bcoromina
@bcoromina
I've seen the ContentTypeTest.scala but it doesn't include the rendering of the response
Naoki Takezoe
@takezoe
@bcoromina You can set Content-Type by contentType = "text/cvs;charset=utf-8" inside your action.
bcoromina
@bcoromina
@takezoe sorry, what do you mean by 'inside your action'? indide the case class ActionResult?
Naoki Takezoe
@takezoe
@bcoromina like this:
get("/hoge") {
  contentType = "text/cvs;charset=utf-8"
  Ok(file.content)
}
