Staring from day one of PDT project, a feature request screaming "Support smarty template syntax coloring" was very popular in our bug tracking system. Twenty-three people voted for this issue, many posts were written about it in the newsgroup and users keep sending us e-mails hoping their request is going to be fulfilled in the near future.
Well... if I understand the Eclipse Foundation correctly, PDT developers shouldn't operate fast and fix these kinds of features. PDT was built only as a "PHP Development Tools framework". In the PHP world where there are hundreds of core extensions and dozens of frameworks it is impossible to support all of them.
But... a feature request is a feature request. And feature requests are meant to be resolved. Applying simple logic rules derives that - "PDT Gets Smarty".
So the growing eco-system of PDT has a new sibling called 'smartypdt' which is a project that "enables users to develop Smarty projects utilizing the power of PDT" it is a great initiative developed by William Candillon , that was guided by me and we expect Dave Kelsey to join us soon. The results are really great!!!
For now two basic capabilities are provided: syntax coloring and compilation
error analysis. This makes PDT and smartypdt the best development environment
for Smarty developers.
The idea is that frameworks and extension creators will re-use the
functionality presented in this project and provide it alongside their products
to ease the development with PHP under PDT.
