EclipseFP 2.6.1 released!

I've just released EclipseFP 2.6.1. EclipseFP is a set of Eclipse plugins for Haskell development. This is a bug fixing release, mainly for GHC 7.8 support.

Release notes can be found here.

As usual, download from http://eclipsefp.sf.net/updates.

Happy Haskell Hacking!

Just updated my EclipseFP and noticed that everytime I F4 on a keyword and try to open browser from Hoogle's result, it will crash. Do you experience this too?

Vlatko Bašić said...

No, it works correctly for me. I only noticed a slight delay (first F4 was few secs), but results show and double-clicking opens a browser window in editors (also few secs delay) correctly.

Vlatko Bašić said...

Forgot to mention I'm on Ubuntu 12.04.

Wiria said...

Then I suspect there must be something wrong with my JVM.
I'm on Ubuntu 14.04.

Thanks anyway Vlatko

Impossible to download :
which gives
a 404 error... with
1. Server: eclipse.sourceforge.net
2. URL path: /updates
3. Error notes: NONE
4. Error type: 404
5. Request method: GET
6. Request query string: NONE

What can I do?

JP Moresmau said...

Use Eclipse? you don't download via browser, you just configure an update site pointing to http://eclipsefp.sourceforge.net/updates/

JP Moresmau said...

But Jean-Pierre you were right the message on the HTML page pointed to the wrong address, fixed.

jean-pierre Grumetz said...

Yes, now it's fixed but after that I was unable to install all the packages downloaded by EclipseFP. I had lots of errors with notably "setup-Cabal- does not exist".
I had to uninstall Haskell 64 bits and install Haskell 32 bits and there, everything was correctly settled.
I think there is a bug in Cabal because in fact setup-Cabal- existed !

But now I would need a guide for EclipseFP and an example of project... Do you know something which can help?

JP Moresmau said...

Well EclipseFP contains cheatsheets for the initial steps (creating a project, running it, etc). Also the book Begining Haskell (http://www.apress.com/9781430262503) shows examples of using EclipseFP. The EclipseFP website also shows some screenshots.

Unable to install EclipseFP.
I have cabal 1.18 and it seems that scion-browser needs cabal < 1.17 in order to be installed in sandbox.
Do you need part of the log in Eclipse console?
What can I do?

JP Moresmau said...

No, scion-browser works fine with Cabal 1.18 or more, your conflict is with something else. You can always install scion-browser in its own sandbox if it conflicts with something else.

Jp Ztem said...

Is it rather SourceGraph?
I'm giving you the last part of the log because I don't know what do...:

Backjump limit reached (change with --max-backjumps).

Note: when using a sandbox, all packages are required to have consistent
dependencies. Try reinstalling/unregistering the offending packages or
recreating the sandbox.

JP Moresmau said...

Yes, Sourcegraph is problematic, so in 2.6.2 it's not installed by default anymore. I've just released 2.6.2 with new versions of scion-browser and buildwrapper, why don't you try to install the new version?

Jp Ztem said...

I follow the method in


and in there, I have no choice... I'm taking what Eclipse is downloading from

I didn't know if half an hour ago
I downloaded 2.6.1 or 2.6.2.

What is the version now on http://eclipsefp.sf.net/updates ?

JP Moresmau said...

Now it's 2.6.2...

Jp Ztem said...

I'll try and tell you
