Generics from 1.18 not working

[nesymno]

I'm using a package https://github.com/samber/do to implement DI in my project. This package uses at least 1.18 and generics. And when I'm trying to swag init --pd it doesn't work.

cd cmd/api && swag fmt && swag init --pd

I did some research. This issue was mentioned before here, here, and here and it seems to have been implemented here, and released here.

However, having that said, I'm also struggling to get it working nevertheless:

swag init --pd -g v1/v1.go                                                                                                                                        ⇡ master 47m ⬡

try the master branch of swaggo. You can install it with the following command.

go install github.com/swaggo/swag/cmd/swag@master

@mrusme - looks like the fix for that bug made it in #1310

[mrusme]

@TomHellier thank you for pointing it out / linking the PR!

Thanks so much, it works! And, as I understood, the fix will be in the nearest release, isn't it?

[TomHellier]

Yes my understanding is this repo gets monthly releases and the maintainer will be doing one soon

The idea of having a 1-month time frame between releases is that the new version will get enough window to be tested and to have time to write fixes for known bugs.

v1.8.6 is now available.

[lowang-bh]

why same error to me: pkg/common/util.go:29:14: expected '(', found '['

have try v1.8.8, master branch.

Maybe your swag is compiled by go lower than v1.8
