javascript - Passing configuration to a CommonJS module -

समस्या

मेरे पास जावास्क्रिप्ट के साथ एक वास्तुकला है I मैंने एक कॉमनजेएस मॉड्यूल लिखा है, लेकिन यह एक आंतरिक कॉन्फ़िगरेशन ऑब्जेक्ट ( var config देखें) के लिए कसकर युग्मित है। मैं इस कॉन्फ़िगरेशन का सार करना चाहता हूं, ताकि मॉड्यूल अन्य वातावरण / परियोजनाओं में पुन: उपयोग किए जा सकें।

पृष्ठभूमि

मॉड्यूल एपीआई संचार के लिए प्रयोग किया जाता है, अर्थात् सिर्फ उपयोगकर्ता प्रमाणीकरण वर्तमान में। यह टोकन आधारित है, जिसके लिए मैं टोकन की समाप्ति का ट्रैक रखूंगा, जिससे कि सभी राज्य क्लाइंट-साइड हो सके। EventEmitter और AppDispatcher का कारण यह है क्योंकि यह फेसबुक द्वारा "फ्लक्स" आर्किटेक्चर पर आधारित है।

इस पर कोई भी निर्देश भयानक होगा मैंने निर्भरता इंजेक्शन पर विचार किया है, लेकिन मैं समझ नहीं पाया कि यह कैसे लागू होगा?

एक बहुत सारे पुस्तकालयों ने विन्यास का प्रबंधन किया है लेकिन मैं इसे सरल रखना पसंद करता हूं:

config / index.js 

  var config = {facebook : {key: 'foo', secret: 'bar'}} {} ('./' + (process.env.NODE_ENV || 'विकास')) की आवश्यकता है () config ()) पकड़ (ई) {} module.exports = Config   
  config / production.js   
  var configure = function (config) {config.facebook.secret = ' सुपर गुप्त '} module.exports = configure   
  app.js   
  var config = require (' ./ config ' )

python - Writing Greek in matplotlib labels, titles -

Image
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 ??

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 ...
