Reduce package size

[Yoric]

I'm trying to land as part of Firefox a package that depends on webidl-rs. That's unfortunately not possible because of the following files:

• 1.9M lalrpop-snap/src/newparser.rs
• 1.9M lalrpop-snap/src/parser/lrgrammar.rs
• 1.9M lalrpop/src/newparser.rs
• 2.3M lalrpop/src/parser/lrgrammar.rs
• 832K webidl/src/parser/grammar.rs
• 177K webidl/tests/mozilla_webidl.zip

It would be great if we could find a way to get rid of these files.

For mozilla_webidl.zip and grammar.rs, I believe it's just a matter of adding an exclude in Cargo.toml. For lalrpop-*, I believe that more recent versions don't contain such huge files anymore.

Apparently, I made a mistake and this doesn't remove all the files I thought it would.

Blocked by lalrpop/lalrpop#333.

Also, for some reason, src/parser/grammar.rs is still included despite the exclude.

That one is blocked by lalrpop/lalrpop#280.

Are you sure grammar.rs is still included? It doesn't seem to be there from what I see.

I believe #13 fixes the cause of grammar.rs sometimes ending up in the vendor directory. This could happen when cargo build builds the file out of the Cargo cache ($HOME/.cargo/registrysrc). The build script would then put its output in that cached source directory because of lalrpop/lalrpop#280. Later runs of cargo vendor then copy the source from that directory, including the generated file.

I'm going to keep this open until lalrpop/lalrpop#333 has been dealt with.

[Yoric]

Ok, at least a new version of lalrpop has just landed (0.15.0), which includes lalrpop/lalrpop#295. That should take care of some of the files.

[sgodwincs]

I'm currently trying to get a new version out, but there's a problem with the include! used. I opened an issue lalrpop/lalrpop#350.

[Yoric]

Lalrpop is just issued a fixed version. @sgodwincs Could you give it a try?

Barring any accident, this is the last blocker for https://bugzilla.mozilla.org/show_bug.cgi?id=1437004, so I'm eager to land it :)

[sgodwincs]

@Yoric Version 0.6.0 has been released. The only change you should have to make is that the Parser struct has been removed, and you can just directly call the parse_string function.

Let me know if there are anymore problems, I'm going to close this for now.

[Yoric]

As far as I can tell, this does the trick.

Thanks!

... and the problem seems to reappear with 0.7.0 :/ Investigating
