Cursive creates invalid Clojure namespaces?

I have a project that has a hyphen in its name (e.g., abc-def).  When I create a new Clojure namespace (e.g., ghi) using IDEA/Cursive it creates the ghi.clj file but uses the hyphenated name in its 'ns' statement: "(ns abc-def.ghi)".  This should be creating the 'ns' statement as (ns abc_def.ghi).  I can't tell you the amount of time I've spent debugging code because of this one simple oversight.

Generally speaking, Clojure always has hyphens in code and underscores in filenames and maps between the two as such. So the hyphen in the namespace and underscore on disk follows that convention.

Yes, this behaviour is correct - Clojure usually uses hyphens in names, but those are mapped to underscores in file and directory names in the file system.

Cheers,

I'm not sure how I should be using IDEA/Cursive together with command-line Leiningen.  The behavior between IDEA/Cursive Leiningen and command-line Leiningen seems to be different.  

I started running into these differences almost immediately and I'm not sure what I'm doing wrong.  I've taken it back a step to the simplest state that has this problem...  setting up a skeleton Leiningen project on the command line (zyx-wvu) and under IDEA (abc-def) and I still run into problems.

Setting up a simple Leiningen project on the command line works without any problems:

Setting up a Leiningen project in IDEA/Cursive behaves differently:

Running the Leiningen task fails:

I'm running Leiningen 2.9.3-1 on Java 1.8.0_261 Java HotSpot(TM) 64-Bit Server VM on the command line.

Any guidance you could give me as to what I'm doing wrong here would be appreciated!

Hi Peter,

In the command line version, you have a :main entry in your project.clj, which is missing from the version in Cursive. That's required so that lein run knows what to run.

Cheers,
Colin

So... shouldn't Cursive have that same :main entry in its project.clj file?

Thanks,

Ah, I see the difference - when you created the project on the command line, you used "lein new app zyx-wvu". The "app" part of that is the template name. To achieve the same in Cursive, put "app" in the Template field.

Cheers,
Colin

what settings do I need to set to make it so whatever I do in IntelliJ it never formats my code in any other way than 2 spaces indented ? I never want it to align expressions over to the right in odd ways or any of that.

had that checked for ages - it doesn't work - try using any structural editing and the indenting is all over the place

I'll take a look at this. What that flag does it uses Only Indent for any form without other config, but thinking about it many of the built in forms have config out of the box. Either that flag should make everything use 2 spaces, or there should be another one which does.

BTW I forgot to update this thread. There's a new flag allowing this in the latest EAP. Let me know how it works.
