Compile error when updating to Bootstrap 2.3.2 about less-sbt

[softprops]

It most likely does have todo with the version of less bootstrap uses. I'm actually in the middle of extract the less compiler the plugin uses as a standalone component. Which the next version of less-sbt will depend on. I was hoping there'd be no issues between now and sbt 0.13.0 but I can try to get one more release out for sbt 0.12.* projects that run into this issue. bootstrap is pretty darn popular! I'll look into this issue and see if the newer version of the less compiler fixes the issue. I do have a test just for bootstap so I should find out pretty soon.

just from a glace it does look like a change in the compiler - https://github.com/cloudhead/less.js/blob/master/CHANGELOG.md#140-beta-1--2 I'll try to get a release out soon

Thanks for looking into this. Now that you mention it ...

https://github.com/cloudhead/less.js/blob/master/CHANGELOG.md
1.4.0 Beta 1 & 2

(~"@var") selector interpolation is removed. Use @{var} in selectors to have variable selectors

The LESS milestone 1.4.0 seems to be at Beta4 at the moment with no open issues. Perhaps it would make sense to wait till the final version is out before you push this out as a release. For me, at least, I have a functional workaround, so waiting a little longer would really not be a problem for me.

Small update on this issue. I can at least reproduce a slightly different error in sbt with in an updated scripted test with the latest version of bootstrap This tree depends on a snapshot version of the extracted compiler which has interfaces for both less 1.3.3 and 1.4.0 ( beta ). The plugin currently uses the 1.3.3 interface. Having this as an automated tests help so I'll keep you posted when I get a clean compile with the bootstrap less sources.

Any progress on this?

hrm, could have swore I fixed this. I look into it this weekend.

I tried to use your lesst branch by installing it in my private nexus, but never got i working. Got weird errors from less compiling bootstrap 3. Went over to sbt-less and finally got a working less 1.4 compile. Thanks anyway!

I'll work on this this weekend. What version of sbt are you on? Sbt 0.13.0 is right around the corner, a number of people are on the lastest rc ( included me ). I ask be sbt compiles on 2.9.2 will 0.13 is on 2.10. I can publish a 2.9.2 version of lesst but if you don't need this for sbt 0.12.* Ill just going to target scala 2.10+

I upgraded to less 1.4.2 and wrote some tests for less's breaking change listed on http://lesscss.org/ in the 1.4 release line in the lesst project ( which the next and all future releases of less-sbt will use. So if you still see this issue in the next version of sbt is a bug with my plugin and not the my adaptations to the less compiler.

[softprops]

Did the first step - http://notes.implicit.ly/post/58547977906/lesst-0-1-0. Next Ill publish a version of less-sbt that uses this. I don't think it would be hard to publish for both versions of sbt. I published less for 2.9.2 so I don't think it will be a problem

Give this a spin and let me know if it solves the issue

addSbtPlugin("me.lessis" % "less-sbt" % "0.2.0")

And now 0.2.1! see #32
