Error: type mismatch Expression: httpbeast.initSettings

Does the Custom router code on the README still work?

import asyncdispatch, jester, os, strutils

router myrouter:
  get "/":
    resp "It's alive!"

proc main() =
  let port = Port(parseInt(getEnv("PORT")))
  let settings = newSettings(port=port)
  var jester = initJester(myrouter, settings=settings)
  jester.serve()

when isMainModule:
  main()

dotenv -o -f ".env" nim c -o:bin/app -r src/app.nim

Returns this compliation error:

~/.nimble/pkgs2/jester-0.6.0-4834f85e61ae39f6b6acfb74d3bbba62d8779b66/jester.nim(531, 29) Error: type mismatch

Hi @ejstembler

The example works fine for me with jester == 0.6.0 and httpbeast == 0.4.1/0.4.2. It looks like you are compiling against an old httpbeast version.

1. What's your Nim compiler?
2. What's your httpbeast version?

Please try to compile with --forceBuild:on and in the compile log find the folder reference to httpbeast and ensure, that it's actually pointing to your httpbeast == 0.4.1 folder. I have the same httpbeast with checksum b23e57a401057dcb9b7fae1fb8279a6a2ce1d0b8 and that includes the full initSettings() proc.

Jester + Httpbeast on Nim v2.0
You are running Jester with Nim v2.0. There's a known problem with Httpbeast, since dom96 has not created new tags for it. I'm using this fork: https://github.com/ThomasTJdev/jester_fork which uses this fork: https://github.com/ThomasTJdev/httpbeast_fork. Please see:

• Request: Make Github tag for version 0.4.2 httpbeast#91

@ThomasTJdev I tried removing jester and httpbeast, then re-installing jester. However, the error persists.

Where can I find the compile log? I didn't see any reference of it at Nim Compiler User Guide.

What else should I try?

Thanks.

Hi @ejstembler

1. I'm not familiar with Mac - so I can only test on Linux. I don't know whether that could affect it.
2. There has been some trouble for some users when upgrading from Nim v1.6.x to Nim v2.0.x with the nimble-packages. Some users had to delete the .nimble/pkgs* folders. Maybe try using the nimbledeps folder to ensure that it's the correct packages: https://forum.nim-lang.org/t/11293#73882
3. The compile-log is truncated in your message - all the ........... Try to compile with --forceBuild:on and then inspect the the compile outputs directory references to the httpbeast folder, which should be like: CC: ../../.nimble/pkgs/httpbeast-0.4.2/httpbeast.nim

If that's not providing any answers, then you might want to try https://github.com/guzba/mummy with https://github.com/ThomasTJdev/mummy_utils
