How do I make an sbt plugin for compiler plugin with cross build support -

-

I have an SBT-plugin that updates the Skelek option to add the compiler-plugin with the release of Scala 2.11 I need to change the version of the compiler-plugin based on the version of skeleton used in users' projects.

I understand that SBT itself uses 2.10, so I think my SBT-plugin should be compiled with only 2.10.

However, I change the version of the compile-plugin to build on runtime. At the moment I do this:

Val device settings: Seek [setting [_]] = {sec (library dispersion + = "group" %% "artifact"% "version%" range)}

Is this the right thing to do? I only have one SBT-plugin release (2.10) and tries to find the correct compiler-plugin version (2.10 or 2.11) on runtime.

In addition, the SBT-plugin is the compiler-plugin, so I declare that as a general dependency in build.sbt. In this case SBT-plugin will only use version 2.10?

I am not quite clear what are the actual questions, but here are some ideas that came to my mind. :

  • SBT plugins are your building project-dependent libraries, which will not affect your actual project code or classpath. Therefore, your plugins for SBT 0.13 series have been published at Scala 2.10.
  • Scala compiler plugins are stored in scalacOptions . By declaring library dependencies on the Sbt "plugin" configuration, it can be managed for you. See.

    Then something like this should be done: 

      wal device settings: seq [def.Setting []] = Seq (libraryDependencies + = "com.example" %% "foo_plugin"% "0.1.0"% "plugin", scalacOptons + = ("-Pfoo: base-directory:" + (scalaSource in compiling) .value .getAbsolutePath ))

c# - LINQ to Entities does not recognize the method 'Int32 IndexOf(System.String, System.StringComparison)' method -

I have performed a linq query using Entityframework as below GroupMaster getGroup = Null; GetGroup = DataContext.Groups.FirstOrDefault (item = & gt; keyword.IndexOf (item.Keywords, StringComparison.OrdinalIgnoreCase)> = 0 & amp; amp; item.ISNAmd) I found an exception like the method when executing it LINQ units do not recognize the 'Inter 32 index of (system string, system. String compromise)' method, and This method can not be translated to Store expression. Includes () method is sensitive by default, then I need to convert to minimize. Is there any method in which a string match match is examined and whether there is any method to solve the index question of the method? You actually have four options Databases globally Change the colon of it can be done in many ways, a simple Google search should reveal to them. Change the mix of individual tables or columns. Use a stored procedure and specify the call statement on your query Perform...

Pygame memory leak with transform.flip -

-
Today I came across an interesting issue which, by writing a small side scroller, instead of a sprite sheet, I was planning to use because I lacked a good "packer" for making phantom sheets (and honestly with patience and passion as it is only a test project). Anyway, I showed the animation running on the right of 8 PNG (with transparency). I considered it a good idea to prepare the flipped images to run on the left in the consultant, and the frame is not framed when the game is running (Flip actually consumes a lot of CPU like I Was measured). > To get access to the loop, I get the memory leak self.move_l = [# 8 PNG images with transparency to the right] For the self in IMG. Move_l: self.move_r.append (pygame.transform.flip (img, true, false) error traceback: traceback (most recent Call final): The file "D: \ Python 34 \ _Projects \ efg \ efg.py", in line 196, in the & lt; module & gt; main = master program ((1024, 680)) "D: \ Python ...

python - Writing Greek in matplotlib labels, titles -

I'm trying to write some text for labels, shape titles etc. with my plots, but no benefit till now Has not happened . I do not want to print specific characters (I know how to use special characters), I want to write the entire text in Greek (maybe Unicode and text ' ?). , suggesting that I would like to mention that for some reason I can not get matplotlib to cooperate with Tex (using IPython notebook from Anaconda in Ubuntu 14.10) so that there really is an option Will not be the first. I tried loading the Arial font and it loads successfully but again I get square blocks instead of characters. I import matplotlib.font_manager FM PROP = FM Font Properties (fname = '/ usr / share / fonts / truetype / msttcorefonts / Arial.ttf') And then to display the string I u'Î? ? I ?? Î¿Ï ??
