feat: new realm /r/demo/microblog

[schollz]

Description

This is a realm exploring the idea of microblogging, where each page is routed by the user's address and each page shows a sorted list of entries from that user. This is a starting point for future realms that may incorporate incentivizing of posts, but wanted to get a working MVP. I believe this realm also serves as a nice intro into Gno (similar to blog) but here it has an exceedingly simple API and demonstrates the utility of content addressing.

How has this been tested?

Yes, I've tested this by setting up my own genesis block and using that to add the package, realm, and submit posts to the realm.

This check is failing on the CI:

go run ./gnovm/cmd/gno build --verbose ./examples
./examples/gno.land/r/demo/microblog
github.com/gnolang/gno/examples/gno.land/p/demo/microblog
command-line-arguments
# command-line-arguments
Error: examples/gno.land/r/demo/microblog/microblog.gno.gen.go:30:2: imported and not used: "github.com/gnolang/gno/gnovm/stdlibs/stdshim" as std
Error: examples/gno.land/r/demo/microblog/microblog.gno.gen.go:53:24: cannot convert "" (untyped string constant) to interface{Error() string}

I don't understand why. I can run the same command on my local repo and it reports no errors.

I don't understand why. I can run the same command on my local repo and it reports no errors.

The difference might be that the CI runs gno precompile before gno build. To streamline the process, I suggest making precompile automatic when build is called. Can you please look into this, @harry-hov?

To improve error clarity, it would be helpful to display the mapped .gno line for each generated .go line. This will provide better context for developers to debug the errors.

Thanks that was the trick I needed. I added that to my workflow and I'll be able to catch these errors from now on.

I love the idea 💯

Thank you for opening up the PR 🙏

I've left a few comments we should discuss before merging

[schollz]

Thanks @ajnavarro, @zivkovicmilos will make edits for these this weekend! Appreciate your help.

great realm 👍

I personally find Page for the user's posts confusing. (page makes me think of pagination, of a limited set of entries). What about Feed or Profile?

Have you thought about possibly integrating gno.land/r/demo/users for friendlier names? :)

Yes, @thehowl - this is a great idea. I'm not sure about the strategy do I either

1. make a realm-to-realm call for /r/demo/users data (if so, how?)

OR

2. import /r/demo/users into /r/demo/microblog

?

[thehowl]

@schollz just do an import! a key feature of gno is that realm-to-realm calls are done just by importing the realm :)

[schollz]

Its much better now, thanks @thehowl . The microblog now automatically displays user names if they are found in the users realm.

pre-approving, looks good everywhere else 👍
