devel gets breaking changes all the time, I intend to apply fixes once the new version is released. Also, when using devel, remember to install latest Nim compiler to the nimble repo: do nimble install from Nim's folder. That should fix your first error.

[rama0x9]

not working on first error, after doing nimble install in the devel folder ~.choosenim/toolchains/nim-#devel/ and then nake build i get

[...]
Hint: rodutils [Processing]
/home/rama/.nimble/pkgs/godot-0.7.14/godotapigen.nim(9, 26) Error: type mismatch: got <string>
but expected one of: 
proc getIdent(self: IdentCache; identifier: string): PIdent
proc getIdent(self: IdentCache; identifier: string; h: Hash): PIdent
proc getIdent(self: IdentCache; identifier: cstring; length: int; h: Hash): PIdent

expression: getIdent(ident)

I understand that it's tedious to keep up with the regular changes on devel, so don't worry, i don't need the latest. I only need a working devel build because there are some nim packages which require >0.18.1 and i want to use them.

[endragor]

Did you also nake clean after installing the devel? nakefile needs to be recompiled since it depends on Nim compiler through godot API generator module.

[rama0x9]

sure, it's the first thing i do if something not working.
But in this case with compiler 0.18.1, nake clean breaks everything because if i build with stable, switch to devel and build without clean, it compiles.
But If i clean with stable, switch to devel and then build, this error happens, now both nake build & nake clean are showing that error, even after i switch back to stable. To make it work again i need to remove compiler 0.18.1

I am having the same error:
/home/rama/.nimble/pkgs/godot-0.7.14/godotapigen.nim(9, 26) Error: type mismatch: got

proc getIdent(self: IdentCache; identifier: string): PIdent

@Zireael07 are you using Nim v0.18 or 0.19?

[Zireael07]

0.18
(The docs page for the bindings says >= 0.18 is fine)

[zetashift]

@Zireael07 I can't reproduce your error. I cloned the godot-nim-stub and ran nake build and it compiles fine. Using v0.18 and windows 10

[zetashift]

..\..\..\.nimble\pkgs\godot-0.7.17\internal\godotstrings.nim(41, 8) Error: usage of 'isNil' is a user-defined error
       Tip: 11 messages have been suppressed, use --verbose to show them.

Yeah, hoping that fixing the 0.19 changes will be easy. Will the new version also work with 3.1?

[zetashift]

Most of the fixing I could do was change the isNil's and equals to an empty seq and empty string.
Should I make a PR so far with my progress or do you already have a branch up endragor?

[dom96]

Pro Tip: The Nim compiler sources are a moving target, pin the compiler package version to something that works and you won't have issues like this again. (For example requires "compiler#mygithash")

[zacharycarter]

I think there are two separate issues being discussed now - one regarding choosenim and pinned compiler versions and another regarding API codgen errors.

The latter issue can be solved by changing any calls to getIdent in godotapigen.nim to include an indentCache.

I created one in this file - var gic* = newIdentCache() - and then used it as the first argument to all getIdent calls in that file. With 0.18.0, this code compiled fine.

I can issue a PR if desired

Hi, I'm running into the .nimble/pkgs/godot-0.7.17/godotapigen.nim(9, 26) Error: type mismatch: got <string> error. What's the best way to deal with this currently?
