New expression parser for OPT 2.1

Open Power Template Tagged under: development OPT2

The incoming Open Power Template 2.1 will have a new, more powerful expression parser. Basically speaking, expressions are those pieces of language that evaluate something, producing a value, i.e. variables and operators. Both OPT 1.1 and 2.0 use a nice, manually-written parser that compiles them to a PHP code, validating their syntax and performing some extra transformations. While it works well, I think I reached the end of possible ways to extend it. It would be simply too complicated to implement new features to it, so I decided I must rewrite it into a formal grammar. Today, the main works on it are finished.

New OPT tutorial

Other Tagged under: OPT2 tutorials

I have published a new tutorial for Open Power Template today. It shows how to use sections and data formats for OPT. I chose this topic, because I noticed that some users have problems with understanding them and decided that an extra tutorial would help them. Before the end of the year, I'll try to write one more text about working with XML in OPT. The article is available on Invenzzia website both in English and Polish language versions.

Open Power Template 2.1 - a closer look

Open Power Template Tagged under: development OPL OPT2

In this note, I would like to show some new features of the incoming Open Power Template 2.1. The new branch, which is currently under development, will bring many new tools and improvements to the template language syntax and the library API. Some of them are already implemented, but there is still a lot of work to do. It is hard to say when it is going to be released, but I'll do my best, so that you would not have to wait another year for it.

In this short entry, I'd like to make a small introduction to the project history for you, as it is quite interesting and could give some clue, how this all began.

Open Power Template 2.0-RC1

Open Power Template Tagged under: OPT2 releases

Finally, the first Release Candidate of Open Power Template is available to download, after 4 months of testing and implementing the remaining features. The library seems to be completed and stable enough for both development and production environments. Of course, there is still a small possibility that a fatal bug will be found, but I do not think this will happen, as there are lots of unit tests present and the code has been checked with two real-world web applications.

Zend Framework port is available!

Projects Tagged under: framework OPL OPT2 releases zend framework

I've recently uploaded the first revision of Open Power Libs port for Zend Framework to our SVN repositories and it is available there for public audience. The port is not completed yet, but the basic functionality is present and seems to work. I encourage everyone to test it and submit suggestions or noticed bugs. The package includes a test ZF application, and the source code is well-commented. I'll put some extra information on wiki soon, as well as set up the "real" user manual.

Zend Framework port for OPL

Projects Tagged under: development framework kohana OPL OPT2 zend framework

One of the goals in the OPL project is not only to provide a set of great libraries, but also teach the popular PHP software, how to use them. Currently, lots of applications are designed with the help of frameworks which often provide their own solutions. It is obvious that the users do not want to deal with all the integration stuff, especially if the library is in fact a replacement for a whole part of the framework. This situation perfectly suits to Open Power Template that is rather a presentation layer framework than just a simple template engine. Currently, the programmers may already use OPT in Kohana Framework thanks to the efforts of Damian Nowak who prepared a nice port. And now, we would like the announcement of the Zend Framework port that will be released soon.

OPT 2.0-beta2

Open Power Template Tagged under: development OPT2 releases

It's true, the new beta version of Open Power Template is available to download. It was planned to be released a week ago, but because of problems with SVN I didn't manage to do that (again, but hopefully for the last time). This is mostly a bugfix release, but there are some small improvements and changes in the component API, which was not documented then. The changes are not too big and were quite necessary to be introduced.

OPT 2.0.0-beta1 released

Open Power Template Tagged under: OPT2 releases

Well, after many adventures with SVN and recently discovered problems with XML prologs and DTD I finally managed to release the first beta version of Open Power Template. From now, we are going to focus on removing as many bugs and problems as possible and we need here your help. Furthermore, we also need to complete the English manual, which is quite big now, but still does not explain some issues.

SVN layout changes in OPL

Tagged under: development OPL OPT2 svn

Merry Christmas everyone! We've had a small delay with OPT 2.0.0-beta1 concerning SVN problems, but they seem to be solved. After the Christmas, we are planning to make important changes in OPL repository layout and everybody whose scripts depend on checking out should upgrade their paths. It is connected with introducing the independent development cycles for each library. The details can be found below.

One year of hard work

Open Power Template Tagged under: development OPT2 releases

Somewhere in the middle of November 2007, I wrote the first (working!) lines of the Open Power Template 2.0.0 source code. After a year of hard work, I've already uploaded a revision that finally gives you all the invented features implemented. For that time, OPTv2 grew and changed its shape. The first development releases resembled OPT 1.1.x when it comes to API and some features. They were just ported to the new XML compiler. Nowadays, OPT is a totally different library. It is much more modularized and designed to make the integration with frameworks easier. There is still a lot to do. The incoming release will be the last one with the "-dev" prefix, and in the next few weeks, the beta versions will appear, then Release Candidates and at last, the first stable release.

OPT requirements

Open Power Template Tagged under: development OPT2 optimization

I've found a new entry on the bugtracker recently. The author informed that he gets "Nesting level too deep - recursive dependency" error while running the development examples provided by the newest OPTv2 dev version. I looked at it deeper and found out that he lowered the default nesting level limit 4 times from 64 to just 16. Obviously, this is a quite drastic change and would affect not only OPT, but many other scripts as well. However, I think it is time to take a look at the OPT issues concerning the requirements, because several of them needs a deeper explaination.

OPT 2.0.0-dev5

Open Power Template Tagged under: components development OPT2

The new development version became available a bit later that I planned, but on the other hand, I managed to add much more new things. The DTD issue is solved, as well as XML prologs, CDATA support and code escaping. The expression compiler is done and the programmers may use now brand new component implementation. This is a significant step towards the first beta release and the end is closer than further. There are only a few instructions to code, the rest is almost completed and works. The compiler, programmers' API and most of the stuff also works. I think of making the first real tests on my home website and creating the Open Power Forms library compatible with the new OPT.

OPT 2.0.0-dev4

Open Power Template Tagged under: OPT2

There is a new Open Power Template development version available to download. The project begins to gel, as the main parser class is almost completed. Inspite of the output cache system mentioned earlier, I've implemented new instructions and completed the snippets. It means that all the template inheritance should work now. I hope the library will be usable by the end of this month. The real projects are really necessary to detect possible bugs and various shortcomings.
