symbols

So.. This is (to me anyway) the most important feature of this program. I need this to work. Please don't laugh.. (okay you can laugh) but when my program errors, I want it to display this: _ _,---._ ,-',' `-.___ /-;' `._ /\/ ._ _,'o \ ( /\ _,--'\,','"`. ) |\ ,'o \' //\ | \ / ,--'""`-. : \_ _/ ,-' `-._ \ `--' / ) `. \`._ ,' ________,',' .--` ,' ,--` __\___,;' \`.,-- ,' ,`_)--' /`.,' \( ; | | ) (`-/ `--'| |) |-/ | | | | | | | |,.,-. | |_ | `./ / )---` ) _| / ,', ,-' ,'|_( /-<._,' |--, | `--'---. \/ \ | / \ /\ \ ,-^---._ | \ / \ \ ,-' \----' \/ \--`. / \ \ \ Echoing each line doesn't work...

Is it possible to split a symbol without first converting it to a string? For example, I've tried :split_this.split("_") and it only returns an error. I've looked through the Symbol class reference , but all the example use to_s to convert it to a string. I know I can convert it to a string, split it, and convert the two substrings to symbols, but that just seems a bit cumbersome. Is there a more elegant way to do this? Since Ruby 1.9 some string's features are added to the Symbol class but not this much.The best you can do, I think is: :symbol_with_underscores.to_s.split('_').map(&:to_sym)

Actually, I want to display the currency symbols of all currency codes and I'm using code like this,but i only get "$" symbols -(void) showCurrenciesList { NSNumberFormatter *numFormatter = [[NSNumberFormatter alloc] init]; [numFormatter setNumberStyle:NSNumberFormatterCurrencyStyle]; //[numFormatter setLocale: [NSLocale currentLocale]]; NSMutableArray *aryAllCurrencies = [[NSMutableArray alloc] init]; //NSLocale *locale = [[[NSLocale alloc] initWithLocaleIdentifier: @"en_US"] autorelease]; NSArray *currencyArray = [NSLocale ISOCurrencyCodes]; NSLog(@"Currency array : %@",currencyArray); for

Applications compiled on iOS are assigned identifiers (UUID's) at compile time. These identifiers may be revealed by the dwarfdump tool. Does anyone know how UUID's are generated and what information may be encoded within them? Almost certainly they're generated by the CoreFoundation UUID machinery, which creates them based off of the MAC address of your ethernet card, the timestamp, and some other miscellaneous information. You can generate your own UUIDs by running uuidgen . As for the information encoded in them, all that's really there is fragments of your MAC address. Pretty much the only

How can i write H2o in the title of a plot? H2 works: plot(main=expression("H"[2]),0) H2O fails: plot(main=expression("H"[2]"O"),0) This solution will work only, if i have a space in front " " plot(main=expression(" "*H[2]*"O"),0) You were close. This works: plot(1:10, main = expression(H[2]*O)) The reason for this is that the 2 is a subscript to element H and you want to position element O next to the H . The notation x * y in an expression means juxtapose x with y , i.e. place x and y together. See ?plotmath for more. 来源： https://stackoverflow.com/questions/13147591/chemical-formula-or

I want to create a symbol equal to that of a private MethodMirror's simplename. However, Symbol's documentation states the argument of new Symbol must be a valid public identifier. If I try and create a const Symbol('_privateIdentifier') dart editor informs me that evaluation of this constant expression will throw an exception - though the program runs fine, and I am able to use it without any issues. void main(){ //error flagged in dart editor, though runs fine. const s = const Symbol('_s'); print(s); //Symbol("_s"); } It seems the mirror system uses symbols. import 'dart:mirrors'; class

I know how to get Flash CS4 symbols into Flash Builder via .swc. The class names become available in the main class, but I can only instantiate those one by one, writing each name into the code. How can I loop through the .swc and load its assets in an array without mentioning their name, then obtain and use these names for instantiation? ideally, something like (half-assed pseudocode): the_instances: = new Array for(i=0; i<the_SWC.length; i++) { tmp = new eval( the_SWC[i].name + '\(\)' ) the_instances.push( tmp ) } or anything else to get those names in a loop. You have at least 2 options.
