Feature/serde feature

[sunng87]

Fixes #50

Added a feature flag to use serde_json as type system, while keeping rustc_serialize as default implementation. Backward compatible.

[sunng87]

This feature is almost down except an example for serde, that works on both stable and nightly channel.

[sorenhoyer]

After testing this locally, I now have this new serde_json feature running successfully with my local fork of handlebars-iron, so I can confirm this is working fine :-)

[sunng87]

@sorenhoyer Are you on nightly or stable? I'm on nightly and blocked by an upstream (quasi_macros) failure for now.

[sorenhoyer]

sorenhoyer@24b9e79 - this seems to solve the quasi_macros compile error, and lets the tests run using "cargo test --features serde_type --no-default-features"

(tested on nightly, doesn't have stable installed on my pc)

[sunng87]

@sorenhoyer thanks! I will try default-features=false on serde_codegen

[sunng87]

unfortunately I'm getting even more errors with default-features turned off on serde_codegen. I'm on nightly 2016-01-03

There have recently been some changes to rustc which broke multiple projects in the @serde-rs organization (see serde-deprecated/quasi#26 for example).

I am using serde successfully with nightly-2015-12-28 in another project of mine, so this should work here too.

I've also been experimenting a little bit with this branch and so far it's working great!

[sorenhoyer]

@sunng87 just it does work on rustc 1.7.0-nightly (b4707ebca 2015-12-27). If they've made breaking changes once again I guess we'll have to wait a little longer while the rust ecosystem matures a bit :/ What errors did you get?

[sunng87]

@TimNN @sorenhoyer thanks for your investigation! I will wait until serde crates are back to normal.

Interesting that most rust developers are still on nightlies even after half a year of stable release.

[sunng87]

We are almost there! I can compile and run the example on nightly 2016-01-03. But it seems the latest nightly breaks rand crate again.

[sunng87]

Oh I finally get these tests passed! Will merge this soon.

[sorenhoyer]

Cool. Great job. Thanks!

[sunng87]

This feature has been released in 0.13.0. Let me know if there is any issue with it.

Document is coming soon.
