I'm happy to announce Tera 0.4 has been released on crates.io!

Tera is a template engine based on Jinja2 and the Django template language. I say based as it's not a 1:1 port and has some minor differences with them but is close enough that you should be able to use the same syntax highlighting.

This version introduces the last big features:

• Macros
• Multiple level extend, super() and nested blocks
• Autoescape

It also adds the filesizeformat filter thanks to the humansize crate.

Some bits are experimental (named endblock/endmacro, kwargs only) and subject to changes depending on feedback.

There are probably features that others deem essential (please create an issue if you can think of one missing!) but for my own use case it seems feature complete, apart from the missing not operator in conditions. Custom tags would be nice too.

The focus for the next version will be on:

• fixing the inevitable bugs
• add the not operator
• improving documentation: a website and more examples
• improving error handling and reporting (maybe error-chain could help there?)
• optimizations and code cleanup

As you can see, no new big features planned, it will be mostly polishing.

To ensure Tera is easy to use, I'm thinking of making a static site engine using it but that will depend on how much free time I have. I'm currently using Hugo for all my sites but the Golang template engine is godawful.

Making the templates compile to Rust functions is still not planned in the near future. Check out Maud or horrorshow if you want type-safe HTML.

If you want to help you have 2 options: use it and report bugs and/or look at the issues tagged for the 0.5 milestone on github. The code is fairly clean, commented and has lots of tests so it should be easy to jump in.

Thanks to SergioBenitez and yonran for the help!

Other crates🔗

bcrypt (0.1.2)🔗

This one has an explicit name and is stable. I was thinking of extracting the bcrypt specific code from rust-crypto but someone already started on that: https://github.com/RustCrypto so I'll just wait.

dbmigrate (0.2.7)🔗

A CLI tool to general and manage SQL migrations for MySQL, SQLite and Postgres. It is stable and I don't foresee the API or the migration file format changing so I will probably promote it to 1.0 soon.

jsonwebtoken (1.1.5)🔗

Strongly typed JWT library. I like the current API but a few more features are planned for 2.0:

• moving to Serde from rustc-serialize
• implementing the missing algorithms

Issues are created on the github repo so feel free to take one of these before I get to them.

vat (0.1.0)🔗

Validate EU VAT number and VAT rates for each country. Still not entirely sure why I made that crate but I think I'll try switching it to reqwest when I have time.

I also never got around handling errors from the VIES API since it was always working when I was looking at it and they don't (AFAIK) detail their error messages anywhere.
