It’s Coati’s birthday! Let’s do some retrospective
Coati, our cross-platform source explorer for C/C++ and Java is 3 years old today. But wait, how can a software even have a birthday? Well, 3 years ago, on February 24th, we started developing on Coati and committed the first implementation of our main() function to our git repository. And exactly 1 year ago we launched our website coati.io to the public. So I guess it’s fair to call it a birthday.
It’s been an incredibly busy year since our launch. We have had developers from all over the world testing Coati and providing us their feedback. With this post I want to give you a short summary on our biggest milestones throughout last year. Afterwards, I will give a short look ahead as we are slowly approaching our release version Coati 1.0.
Launching a first build to the public
Looking at it retrospectively, we didn’t really know what we were doing when we launched Coati to the public one year ago. There were so many things we hadn’t really thought through at the time. But I’m happy we chose to do it that way, we could benefit a lot from the feedback of our early adopters.
The image on the left shows the interface of our first release build. There wasn’t much change on the surface, but under the hood nearly everything changed since then. What stayed the same was our 3 component interface concept, consisting of search, graph and code, which has proven work really well.
Test Licenses for evaluation
One of the first things people criticised was the lack of test licenses for evaluating Coati before purchasing a license. Indexing your own source code was not possible with the trial build and we thought it was sufficient for developers to test Coati’s user interface on our sample projects. We started offering test licenses via e-mail, which also turned out to be a great way of starting a conversation with our users and collect feedback.
Showed references to local variables
To better support understanding of source code within the function scope, we added highlighting for local variables. Before that we only provided information above function scope level.
Introduced multi-threaded indexing
Decreasing indexing time was probably one of the main goals during last year. There have been numerous improvements, he biggest among them was our move to a multithreaded indexer, which indexes multiple files at once. I’m not totally sure on the numbers, but I estimate we cut down indexing time by about 70–80% over the last year.
Extended project setup capabilities
With more and more people using Coati on more and more source projects we also got a lot of feature requests regarding project setup. There were a lot of configurations we didn’t support at that time. Here are some features that were introduced to our project setup:
- Project setup from compilation database
- Project setup from Visual Studio via plugin
- Defining compiler flags
- Excluding source files from indexing
- Support for environment variables
- Defining source file extensions
Increased search speed
The implementation of our fuzzy search algorithm turned out to perform pretty bad as soon as the indexed project reached a certain size.
We rewrote the algorithm and also improved the design of the auto-completion popup, to show namespace information and file paths in a second line.
Added more code editor plugins
We greatly increased the number of source code editors for communicating with Coati. We now have plugins for:
- Sublime Text
- Visual Studio
Please visit our documentation to find out how to use them.
Added dialogs shown during indexing
Our user feedback during indexing was very basic at first. We only showed some progress information within the status bar at the bottom of the screen. We designed and implemented dialogs for the different steps to provide a better user experience.
Added table listing indexing errors
Similar to the indexing dialogs, we didn’t show errors during indexing that well. We just showed a list of all errors within the source code. Error messages were only available on hover. We added a new log view with an error table listing all error messages to tackle this issue.
Added Java support
Since fall of last year we are also offering support for Java. The indexing is done via JavaParser and JavaSymbolSolver. We have constantly improved our language coverage and look into easier project setup from Java build systems now.
As you can see, we spent a lot of time on feature development during the last year and we are proud of what we achieved. We could fill the biggest gaps in terms of functionality and we are slowly approaching our first release version Coati 1.0. However, there are still a couple of features on the list, that we plan on implementing until then:
- Better indexer crash handling via indexer processes
- Java project setup from Maven
- Faster UI
And one more thing…
There’s a major change about our product coming in a couple weeks. We will change our product name. Please stay tuned for our announcement.
