Cobra Forums

Hey guys, I'm getting ready to cut a new release of the add-in for MonoDevelop and Xamarin Studio and was looking to get some people to help with testing.

New features for this release will include:

* Mouseover tooltips

* Support for parameter completion when typing '(' or hitting Ctrl+Shift+Space when inside parenthesis. Then press up or down to see the different overloads. You can press Esc to dismiss the tooltip if desired.

* Some support for showing extension methods when hitting '.' after an identifier. This doesn't always work due to race conditions with the non-thread safe compiler.

* A new Go To Declaration right-click menu command.

* Support for building with msbuild or xbuild which is the new default in Xamarin Studio and MonoDevelop. This also means you can now compile .cobraproj files from the command line.

* Support for installing via a package repository at http://mdrepo.ramonrocha.com/ This isn't set up yet but the infrastructure and code to create the package is in place (thanks, sephthir!)

Here's a screenshot


The add-in requires the latest version of Cobra from svn. See here for instructions on how to do that: http://cobra-language.com/trac/cobra/wi ... FromSource

If you are running Windows 64-bit, then you need to install Cobra targetting the x86 platform. So, instead of running 'bin\install-from-workspace' you would run 'bin\install-from-workspace -x86'. You don't need to mess around with 'Ldr64.exe setwow' or 'Ldr64.exe set64' anymore.

You can grab the add-in code here: https://github.com/ramon-rocha/MonoDeve ... didate.zip

cd to whereever you unzip it and then run the installer by executing:

Code: Select all

cobra install.cobra

Or on Windows 64-bit run this instead:

Code: Select all

cobra -clr-platform:x86 install.cobra

Oh, and of course you will also need Xamarin Studio. Binary packages can be downloaded here for Windows and Mac.

http://monodevelop.com/download

On Linux, you will need to build MonoDevelop from source which you can grab from here: https://github.com/mono/monodevelop

Installing MonoDevelop from source can be a bit daunting to set up for a beginner so if anyone tries this route and runs into any issues, you can post here and I will try to help.

You can post any issues encountered here on the forums or on GitHub: https://github.com/ramon-rocha/MonoDeve ... ing/issues

Thanks in advance!

I just found Cobra today, and was setting up my environment. I had found your MonoDevelop plugin, and was having problems installing it [with Cobra 0.9.4]. While in the process of debugging, I saw this post pop up here, and immediately switched to the svn version of Cobra.

Everything is working as intended. Built my first Cobra programming (by built, I mean compiled. Not designed! haha.)

Excellent so far, all working on this end.

I'll keep playing with it, and report any issues here!

Thanks for testing it, guys. The more the better.

That warning means you won't be able to build in Xamarin Studio using MSBuild (which you wouldn't be able to do without using the -x86 option anyway if you are on 64-bit). I wonder why it couldn't find it?

What happens if you run the MSBuild target manually? From the <cobra-workspace>\Source folder, can you run this command?

Code: Select all

@DelphiGuy, the switch has an "x" in it:

-x86

Based on the output, it looks like you entered -86 instead of -x86

regarding me using the wrong switch, my response is "DOH!"

regarding the warning, i'll follow the troubleshooting tips nerdzero posed and respond later.
