[ANN] Leiningen support beta

[Laurent PETIT]

Hello,

I'm pleased to announce the availability of a first version of Leiningen support for Eclipse.

This is still beta quality software, but I'd like feedback before I continue adding features.

This Eclipse plugin is currently totally separate from the Counterclockwise plugin, making it easier for me to release both without interfering on each other shoes.

So, there is also a separate Software Update Site for it:

http://ccw.cgrand.net/updatesite-lein-betas

Please tell me how it does work for you!

Tip1 : after installing the plugin, Go to your project's contextual menu, and then Configure > Leiningen
Tip2 : after having installed support, there is a contextual menu entry for Leiningen for the project's root node.

[Laurent PETIT]

As to narrow down the scope : I've focused on proper management of the project's Build Path :

- a "Leiningen Dependencies Container" which holds all deps (transitively) as declared in leiningen
- a Builder which takes care of upgrading the "Leiningen Dependencies Container" everytime the project.clj file is modified
- a Command for resetting the Java Build Path, only invokable "manually" : will reset your source path, add the classes/ folder, etc.

It does not handle (yet) Leiningen plugins/tasks.

Very exciting!  I look forward to playing with it this evening

Ok, first issue reported, which requires to upgrade to a new version of leiningen-core, which cannot be made without adapting to its new API.

Right now, any attempt to download and use the Leiningen support will fail, so please wait for news, and do not try it in the mean time.

News to go probably by thursday.

Cheers,

[Laurent PETIT]

Bug has been fixed and released, you should be able to install and try it, fellow intrepid early adopters !

[Laurent PETIT]

Additional info: I will be able to work on CCW in Thursday. So if I can have some feedback before, it'll be great. 

[Niels van Klaveren]

I've been trying it, and while my project.clj's aren't the most impressive ones, it seems all are handled nicely. And all that without native scripts & bats, which I had some problems with. However, it seems rightclicking folder src in my project > New >  Clojure Namespace now gives an error: "Cannot create Clojure namespace outside a java source folder".

It seems the src folder isn't seen as a source folder anymore (=also shows as a 'plain' folder icon, instead of the folder with brown parcel icon it used to be). Happens both in new and existing projects.

Hi,

Weird, I'll look at that tomorrow. 

In the mean time, does the manual command Leiningen > reset build path help get the src folder back to the required java source path folder it should be ?

Yeah, apparently I released too quickly after having upgraded to a new version of leiningen-core internally. Fixed locally, will be released tomorrow.

Thanks for the report !

That fixed it, thanks much !

I saw the mockups on the wiki, and the whole project looks great (especially for Windos users like me) but will there:
Be a way to create a new leiningen project ?
Be a way to create and execute additional leiningen commands ?

Yeah, eventually, but there are more urgent tasks to do.
Especially, I'd like to have the core logic well tested before building more sugar on top of it.

Yeah, but not in the first stable release.

One of the new features in Leiningen 2 is support for native libraries. For instance, Quil 1.0.0 uses Lein to download the native dependencies.

These are nicely shown in CCW with lein support in the Package Explorer > Leiningen Dependencies >  expand jar > native folder, as well as the subfolder /native/OS/. However, they are not included in the library path of the project.

I was used to open the jar properties and set the native library path there, but these settings are locked (and rightly so) and can only be changed by changes to the project.clj. Trying results in the message "Leiningen Managed Dependencies. Reflects Leiningen Dependencies declared in project.clj.

As a workaround, one can open the Project properties > Java Build Path > Libraries > Leiningen Dependencies > Native Library Location > Edit > Workspace and browse to the native directory.

I'm posting this both to document the workaround as well as ask the obvious: Will the native library support of Lein 2 be included in CCW lein support ?

By the way, not nitpicking. CCW is without a doubt the best Clojure support in any Java IDE, and the first version of lein support is already more than I anticipated.

Yes, definitely. Created an issue if you want to follow progress on this: http://code.google.com/p/counterclockwise/issues/detail?id=343

If I'm postponing the "create a new leiningen project" feature, it's because I think I need more hammock time on this one.
Especially, I need time to contemplate having dedicated support for the lein newnew plugin, once generic lein plugin/targets is in place.

As a workaround, one can open the Project properties > Java Build Path > Libraries > Leiningen Dependencies > Native Library Location > Edit > Workspace and browse to the native directory.

Something weird happens on my Mac: I don't seen the native deps listed as native libraries of the Leiningen container, nor as individual native libraries of Leiningen container entries.
I also took care of deleting the native-deps/ folder created by leiningen-core when it was invoked.

And even without all this in place, I'm able to run a repl, start quill, and draw the first "The moon delights the night" paint.

Is there some already configured stuff making this work out-of-the-box with my Mac book air ?

Should I try with another OS to reproduce a bug ?

Is it Eclise (3.71) ., or the version of the JVM I'm using (Java SE 6 Mac OS X default) ?

[Laurent PETIT]

I just pushed to the Leiningen Software Update  Site ( http://ccw.cgrand.net/updatesite-lein-betas/ ) a new version with Native libraries support.

Cheers,

By the way, I noticed you opted for changing the classpath in the run configuration. Is that because run configurations are created dynamically, and they would work independently of the platform Eclipse is run under ?

Another option might have been to add an attribute to one or more classpath entries in the classpath file

 <classpathentry kind="con" path="ccw.LEININGEN_CONTAINER"
  <attribute
   name="org.eclipse.jdt.launching.CLASSPATH_ATTR_LIBRARY_PATH_ENTRY"
   value="native/windows/x86_64"/>
</classpathentry>

However, this would mean the .classpath file would have to be rewritten when it is loaded on a different platform ?

Not necessarily, if you check in your version control system the .project and .classpath files.


I did it this way because I thought it would be best placed inside what is managed by the Leiningen Classpath Container, rather than a user editable place.

It also allowed me to start playing with some parts of the JDT (Eclipse Java Development Tools) API which I'll need to use again when I'll implement the "Download sources / Download javadoc artifacts" feature.

I have not used Leiningen before,so I thought I would install this to find out what it's about.
Is there any documentation about this?
Your Tip1: there is only Convert to Maven Project on my project context menu.

Any advice how to get started with this?

The menu will only show up if you have a project.clj file in your project root dir (and of course if you have installed the leiningen plugin from ccw.cgrand.net/updatesite-lein-betas

Well yes, of course I installed the leiningen plugin :)

So this plugin can't create a new leiningen-based project? One has to create it outside Eclipse?

[Niels van Klaveren]

You can't directly create a leiningen project yet, I hope that's next on the development roadmap. You can create a normal Clojure project, add a project.clj and switch the project to Leiningen support. However, the default project structures don't exactly match lein's, you even need to manually create namespace subdirs in src etc.

Currently I use lein 2's lein new to make a new project, and lein 1's lein-ccw plugin to create a classpath and project file. This is far from ideal, so I've been wanting to make a lein 2 plugin version of lein-ccw, so a simple lein new ccw should be all that's needed to make and convert a lein project, and make it ready to import through the default eclipse import project.

Being pretty new to Clojure & Leiningen, and doing it as a hobby, this might take me a bit though.

[Laurent PETIT]

Hello,

Yes, the first work has been focusing on the "core problem" of managing dependencies well, not adding the (useful!) additions such as a project wizard, etc.
Please note it's still alpha, and still 0.0.1 version, tho :-)

Especially, I've postponed the creation of a wizard because I wanted to think more about how to add it : specific, or using "lein new new" under the hoods ... ?

Given that what we have is already good, and that the missing piece is only really just a wizard for creating new projects from scratch, I think I'll just do a quick & dirty wizard which does what lein1 currently does, label the whole thing 0.1.0 STABLE, and then start working on additional features ( among them, and high priority, tasks support ).

Yes, I will have to change this.

The idea is that when tasks are available, I'd like to let users be able to create shortcuts for launching their favorite tasks from customized shortcuts. But still have an "umbrella" under which all these shortcuts would be found ( the current not-so-good-idea "Ctrl+L" thingy).

What could be a better pref shortcut which could work for Win/Lin/OS X ?

Maybe Alt + L ?  (then have Alt + L + ...) ?
 

and "run as > clojure app" shortcut Ctrl+Alt+L is not working for me
(don't know if this is related to ccw-lein, however)

My guess is I introduced a regression in a recent "fix" related to Ctrl+Alt+L.
Would removing your existing Clojure "run configuration" ( Run > Run Configuration ... ) fix this ?

Yes, since a week, CCW and Lein integration updatsites have been merged. Now you can grab both, in a single operation, from http://ccw.cgrand.net/updatesite-betas/

You may have to uninstall existing CCW/Lein support the first time.

Hello,

Leiningen support is integrated with counterclockwise 

But currently still in the beta update site:

http://ccw.cgrand.net/updatesite-betas/

Then you can create a new Leiningen project, or project > configure > enable leiningen support for an existing leiningen project.

Maybe you'll have to reset your perspective to get the commands show in the menus.
