We almost done with newer version of Eclipse-based Fantom IDE and plan to release it in the end of this week.

small teaser - http://www.youtube.com/watch?v=zVqHsFs_RJo

key features

• Most part of IDE is written on Fantom
• Usage of sys::compiler API instead of launching external process (much faster on pure fantom projects)
• Integration with Java (can refer to Java projects and libraries from IDE)
• Launching and debugging Fantom code from IDE (including fwt and web server)
• Fant tests launching and debugging
• Support for breakpoints (including closures)
• Advanced completion and type inference
• View Fandoc tooltips by pointing to source elements
• Search for declaration/references of types/slots

Sweet!

These are very good news. I will try it!

Finally, Milestone 1 has been released! Tested with Eclipse 3.5 and 3.6 on Linux, Mac, Windows

Installation instructions

Has anyone else tried installing this, are there elcipse update sites for the dependencies needed. I tried to install the dependencies (ANTLR, EMF, DLTK) manually, but that just did horrible things to my eclipse installation.

I'd love to be able to use eclipse to write Fantom code, does anyone have a more step by step guide to installing everything.

geo, The current update site includes necessary versions of DLTK and ANTRL, the EMF runtime dependency resolves to Galileo or Helios update site automatically, there is no need to install prerequisites now

You can connect to #fantom irc channel and I can assist you in real-time

geo, I've just used the update site (http://download.xored.com/fanide/updates/) and everything went smoothly

ivan, are you using xtext? http://www.eclipse.org/Xtext/

dfreire,

We use Xtext in our company on other projects and quite happy with it, but for Fantom we use DLTK as platform and Fantom-written parser.

Hi, I'm new to both Fantom and Eclipse.

@ivan I'm trying your IDE, and encountered a problem. When running the project, I got this error:

Errors occurred during the build.
  Errors running builder 'Script Builder' on project 'myproject'.
  compiler::CompilerErr: Pod not found 'sys'

I'm on Windows 7, using Eclipse Classic version: 3.6.0

I followed the steps from your screencast. But for the interpreter, I use fan.exe instead of the fan script.

Can you help me with that? Thanks.

Nice video.

I can't seem to get it working for me. It seems my DLTK is 2.0 and F4 won't work with it...

Cannot complete the install because of a conflicting dependency.

I've downloaded a fresh version of eclipse and reinstalled, however others might not want to compromise in such way.

@DanielFath You have DLTK 1.0.2 installed, but F4 depends on DLTK HEAD (just released as 2.0)

Yeah, I figured that one out, but my update didn't work. GC overhead while resolving dependencies.

Regarding my problem, that was because JDK is not installed properly. msvcr71.dll doesn't exist in Windows 7 (or at least not the place that Java can see).

@ivan, it seems to me that the building of pods is not generating the javascript for @Js anotated classes, can you confirm it?

@dfreire,

Yes, looks like we didn't hook all the necessary API :( Created a bug for it

Good work, it works very fine now.

One very small detail, set the default preferences of color highlighting of the dsl expression to bold instead of italic. Italic text is not very fine to read in regular expressions.

@ivan are you able to propose talking about F4 at Eclipse Summit Europe?

http://www.eclipsecon.org/summiteurope2010/submissions/?page=submissions

I am likely to present one or the other project (if they're accepted ;-) so I may help if you feel unable or are too far from Europe...? Eclipse normally doesn't pay your flight or accomodation, just waiving the conference cost.

Hi Keilw,

@ivan is on short vacation now, so let me please reply on behalf of him. He is working at xored software, and we're one of ESE 2010 sponsors. So Ivan definitely will be at the summit this year.

We're not sure if F4 talk would gain much interest at the conference, however some aspects could be interesting. At least ability to write 100% pure Fantom Eclipse plugins, additionally to the fact that F4 is a first eclipse-based IDE written in non-Java programming language...

Anyway, thank you very much raising the point, and we definitely would be happy to participate in relevant events like IDEs for JVM-based languages BoF (like one at eclipsecon 2010 this year), etc. Please feel free to share your ideas and we're open to any cooperation possibilities if you're interested.

Thank you, Andrey

Hi Andrey,

Thanks for the update. I was at EclipseCon, but speaking there myself. So I may have missed the BoF. You seem committer behind the DLTK already, so there are potential synergies especially with UOMo. We haven't specially targeted dynamic languages, but those supporting Units of Measure like Fantom are clearly prefered. Others like Scala with extensions, too.

What can you or Ivan tell me about Q7? The booklet looks interesting. Does it offer an IDE especially to Concordion or related TDD/BDD solutions? If so this may be a big synergy since we currently run a few projects at big companies.

Are you UK-based since many customers are there like BT?

Regards, Werner

Hey Guys,

Back towards the original thread of the topic - do you have an issue tracker that's publicly accessible for F4?

Cheers - great tool (so far it's my pick of the bunch!)

Martin

Hey Martin,

Thank you very much for appreciating the tool, and we're looking forward for bugs/ideas /etc. Bugtracker is here http://bugs.xored.com (you need to signup first).

Kind Regards, Andrey

Ivan, Andrey,

I can't seem to get F4 to work. After creating a Fantom project at a location that already contains a few .fan files, Eclipse goes into "Building workspace" mode and it never exits. The only way out is to kill it.

The .log doesn't contain any errors and I also tried to create the project on a brand new workspace, but same behavior.

I'm using the following Eclipse:

Eclipse for RCP and RAP Developers

Version: Helios Release Build id: 20100617-1415

Any thoughts?

cbeust,

Which version of Fantom do you use in F4? We haven't tested ut on versions < 1.0.52 and I guess that it may not work correctly (however in this case something should appear in error log). Also, while Building workspace... job hangs, can you explore containers like Interpreter libraries and Fantom Native Libraries? Are they contain correct information?

@ivan:

I am trying your plugin to open an existing project (fantomongo) but I keep getting this exception. Is there anyway to get around this?

Great IDE by the way. It works quite well when creating the project from scratch and most IDE feathers are implemented

it seems that the dependency is not parsed when adding existing source to create a fantom project. Edit the depends var in build.fan will trigger the parsing and thus adding the necessary dependencies and it will work fine from there.

Great IDE. feather complete and very fast. Very impressed with its quality at first release.

zyhong,

Thanks for a feedback! I've created an issue in our Jira - http://bugs.xored.com/browse/FAN-400, this definitely will be fixed with a new release.

Can anybody on the project say when Milestone 2 is planned for release?

I'm getting bitten by FAN-393 at the moment, with no known workaround.

Also, there is a typo in the link to JIRA on http://kb.xored.com/display/FDT/F4+Installation+Instructions. The URI scheme is "hhttp" instead of "http".

Hi qualidafial, Right now the installation instructions are located at http://www.xored.com/fantom/fantom-installation and the new update site always contains the latest version (last build was 2 days ago). Unfortunately right now we are not making active development, but today I'm working on some F4 bugs and will take a look at this bug.

Ivan, thanks for the reply.

For what it's worth I found a workaround and posted it to FAN-393. Since following those steps everything is working great.

Thank you again for working on this great plugin!
