all of this seem to have been hardcoded 🙈 well, not like anything broke because of it, but indeed not a good practice.

unless if was intentional? but I can't see a reason.

I can't see a reason either, and we need this unhardcoded moving forward to work with the frame umbrella crate

Def. on the right path, just need more tests.

I recall this was one of the BIG BIG fixes in this PR when I was working on it.
Try this for yourself: if you are familiar with the tt_call pattern a bit, instead of passing in the your_tt_return
, pass frame_support
as it was in the past to the caller. Then have the caller call #frame_support::__private::tt_return
instead of plain your_tt_return
. These two seem equivalent, but the former never worked.

But, hearing what I just said, in the scope of this PR, it is pretty unclear why we are doing this. I recall my working example was minimal-runtime
. Would be good if you also bring back some sort of example here to demonstrate that this change is actually needed. Ideally, this example will just a test in frame-support and not the frame
crate.

Yes, that's what looks at a glance... did you find out what's the reason?

@kianenigma Probably the best example is by using the frame-crate itself, which makes me reconsider if bringing this change here was a good idea and instead bring it in the 'main' frame umbrella PR. WDYT?

I highly suspect that it didn't work before because the "receiver" didn't expect to see any "arguments" named your_tt_return
and have been coded to only recognize frame_support
as an "argument". If you take a look at tt_default_parts.rs
, you'll see what I mean.

If my memory is good, the former didn't work because there was another error when giving a path instead of a single ident:
Like code was something like this:
frame_support = [{ $($frame_support:ident)::* }]
} => {
$($frame_support::)*__private::tt_return! {
but it should have been like this for path to work
frame_support = [{ $($frame_support:ident)::* }]
} => {
// see the semicolon is after the parentheses here
$($frame_support)::*__private::tt_return! {
but when you implemented with your_tt_return
you fixed this kind of error.

macro_magic
might make this easier to reason about perhaps 😇

the specific workaround for passing paths to these btw is to do an interpolation of idents segmented by ::
and with an optional leading ::
. For some reason that just works positionally where path
doesn't,

Relates to #173
As part of the efforts towards making the FRAME umbrella crate in #1337, we need macros to work without
frame-support
,frame-system
andcodec
, andtype-info
being in scope.This PR leaves
generate_crate_access_2018
ready to check for theframe
crate once this one is ready and use its reexports instead of the local dependencies.
