  - by nevalu

  How to create a new data type for Go which to can check/validate its schema when is created a new variable (of that type)? By example, to validate if a string has 20 characters, I tried: // Format: 2006-01-12T06:06:06Z func date(str string) { if len(str) != 20 { fmt.Println("error") } } var Date = date() type Account struct { domain string username string created Date } but it fails because Date is not a type.

• Is it bad OOP practice to have objects reference each other?

  - by lala

  Pardon my noobness. I'm making a game in which several characters have relationships with each other and they need to be able to interact with each other and store some relationship data regarding how they feel about each other. I have an object for each character. Is it bad for each of those character objects to have an array of all the other character objects in order to perform these interactions? Is there a better way to do this?

• How to append to an array that contains blank spaces - Java

  - by Cameron Townley

  I'm trying to append to a char[] array that contains blank spaces on the end. The char array for example contains the characters 'aaa'. When I append the first time the method functions properly and outputs 'aaabbb'. The initial capacity of the array is set to 80 or multiples of 80. The second time I try and append my output looks like"aaabbb bbb". Any psuedocode would be great.

• Regex: Match any character (including whitespace) except a comma

  - by selecsosi

  I would like to match any character and any whitespace except comma with regex. Only matching any character except comma gives me: [^,]* but I also want to match any whitespace characters, tabs, space, newline, etc. anywhere in the string. For example, I would like to be able to match all of this up until the comma: "bla bla bla" "asdfasdfasdfasdfasdfasdf" "asdfasdfasdf", Is there a simple way to do this without knowing where the whitespace may be?

• strict string to int[long]

  - by baskin

  Do we have a standard way of converting a char* to int (or long) in a strict way, i.e. we should get proper result only if all characters are digits and can fit in an int (or long) -- some way by using strtol etc.. ? Thus "sbc45", "4590k", " 56", "56 ", should be all invalid using that function.

• Javascript regex: remove space(s) if not surrounded by a letter

  - by user326433

  I'm trying to clean some html text with javascript, there are white spaces included before and after some words (text is poorly formatted). Currently I have this regex: $("#" + target + " *").replaceText(/([\S][\u05B0-\u05C4]*)/gi, '<span class="marked">$1<\/span>'); This will capture all the non white-space characters and wrap them in a span element, but will not capture spaces between words (I need the span). How would you solve this?

• When does the @ become usefull?

  - by DaNieL

  As you know, the @ characters before a php istruction suppress every eventual warning, error or notice from being raised. Personally, i dont like this tecnique, becose i prefer to handle those errors, and in a real life, the error must no happen or have to be managed. By the way, i find this tecnique to be applied in many scripts (cms plugins, open-source classes). So, could the @ really be usefull (in this case, an example would be appreciated), or is just for lazy developers?

  Can CodeMirror 2 be used to set part of the code to be uneditable? I do not wish to do it like fully editable code. Example: Code inline: example public static void main(String args[]){ //content } I hope to be able to make Line 1 and 3 uneditable BUT able to edit lines in between them adding characters/spaces increasing the number of lines inside the method as we speak AND still unable to edit the starting and closing bracket lines.
