@kitsonk I think I fixed all of them. Can you try again?

Ooops... sorry, I missed this. I am trying now but I am starting to wrap up for my day...

[kdy1]

It's okay, I forget things so well.

@kdy1 I have re-tested with this branch. Thank you for fixing lots of the bugs. There are still a couple things:

• I am still getting a stack-overflow with the example I gave in swc_bundler: does not handle namespace re-exports #1110 on my branch here.

• The output for swc_bundler: export * as wrongly emitted #1118 is still the following for me:

  export * as a;

• I have also been using https://deno.land/x/[email protected]/mod.ts and https://deno.land/x/[email protected]/examples/server.ts as bundling tests, which are complex and exercise a lot of scenarios. I've run it again, and with lots of the other issues fixed, I am seeing a new error (possibly one that existed but I didn't see it because of the other errors). I will try to get that one to reproduce as well, but there is at least another potential bug out there.

@kitsonk Did you invoked typescript::strip before bundling?
I tested but

export * as a from "./a.ts";

works with typescript::strip

Also, I got

error: failed to select a version for `swc_common`.
    ... required by package `deno_lint v0.2.0 (/Users/kdy1/projects/deno_lint)`
    ... which is depended on by `deno v1.4.2 (/Users/kdy1/projects/deno/cli)`
versions that meet the requirements `=0.10.3` are: 0.10.3

while trying to build it

[kitsonk]

@kdy1 I will take a look again...

As far as the building, you would have to clone deno_lint and deno_doc and update the swc to local builds as well... a little bit painful at the moment.

@kdy1 I've looked again, and yes, the loader does the stripping before bundling. Our folding though is a bit more complex than the PR you had done, as we have some other things we need to support. Here is the loader in my PR. I am wondering if some of the other passes are causing the problems/challenges?

I think stack overflow may not be related to bundler.

Also, I can't guess why #1118 is still the issue. export * as a from "./a.ts"; should be removed by typescript::strip, not bundler.

[kdy1]

I'll fix remaining issues with a separate pr
