coding style - The Stepdown Rule in Clean Code -


there stepdown rule (high level function @ top , low level next) in clean code (chapter 3, 1 level of abstraction per function ).
should when use coffeescript since there no function declarations in coffeescript.

example:

 seeamovie = ()->      buytheticket()      watch()   buytheticket = ()->      //some thing   watch = () ->      //some thing

i want this.

coffeescript doesn't affect rule. rule doesn't have declarations, if did, coffeescript does have declarations anyway. @muistooshort said, here's coffeescript function declaration:

functionname = (arg1, arg2) ->    functionbodyline1   functionbodyline2

those parenthesis optional in declaration if there no arguments. here's example of step-down rule in coffeescript in action:

highlevel = ->   dosomethingalmostashighlevel1()   dosomethingalmostashighlevel2()  dosomethingalmostashighlevel1 = ->   dosomethingalittlelowerlevel1()  ...

note edit: that's fine , follows step-down rule. wrong sample?

not mentioned in book, uncle bob clarified me when 2 functions - @ same level of abstraction - use same lower level function, should ordered so:

highlevel1 = -> lowlevel() highlevel2 = -> lowlevel() lowlevel = -> ...

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
