In the quest for localization I need to find all the string literals littered amongst our source code. I was looking for a way to script this into a post-modification source repository check. (I.E. after some one checks something in have a box setup to check this stat) I'll probably use NAnt and CruiseControl or something to handle the m...
A recent question about string literals in .NET caught my eye. I know that string literals are interned so that different strings with the same value refer to the same object. I also know that a string can be interned at runtime: string now = DateTime.Now.ToString().Intern(); Obviously a string that is interned at runtime resides on t...
I'm having a hard time with the setup statement in Python's timeit.Timer(stmt, setup_stmt). I appreciate any help to get me out of this tricky problem: So my sniplet looks like this: def compare(string1, string2): # compare 2 strings if __name__ = '__main__': str1 = "This string has \n several new lines \n in the middle" s...
Similar to Is hard-coding literals ever acceptable?, but I'm specifically thinking of "magic strings" here. On a large project, we have a table of configuration options like these: Name Value ---- ----- FOO_ENABLED Y BAR_ENABLED N ... (Hundreds of them). The common practice is to call a generic function to test an ...
The static analysis tool we use is flagging C code similar to the following as a critical buffer overflow. #define size 64 char buf [size + 1] = ""; memset (buf, 0, size + 1); The tool's error message is: Buffer Overflow (Array Index Out of Bounds): The array 'buf' size is 1. Array 'buf' may use the 0..64 index. Is this legitimat...
How can I encode the Unicode character U+0048 (H), say, in a Powershell string? In C# I would just do this: "\u0048", but that doesn't appear to work in Powershell. ...
Is there any way to have multiline plaintext constant literals in C++, ala Perl? Maybe some parsing trick with #includeing a file? I can't think of one, but boy, that would be nice. I know it'll be in C++0x. ...
I'm attempting to compare two strings with is. One string is returned by a function, and the other is just declared in the comparison. is tests for object identity, but according to this page, it also works with two identical strings because of Python's memory optimization. But, the following doesn't work: def uSplit(ustring): #...
I have a C++ source file and a Python source file. I'd like the C++ source file to be able to use the contents of the Python source file as a big string literal. I could do something like this: char* python_code = " #include "script.py" " But that won't work because there need to be \'s at the end of each line. I could manually copy a...
I have a character array and I'm trying to figure out if it matches a string literal, for example: char value[] = "yes"; if(value == "yes") { \\ code block } else { \\ code block } This resulted in the following error: comparison with string literal results in unspecified behaviour. I also tried something like: char value[] = "...
I need to localize error messages from a compiler. As it stands, all error messages are spread throughout the source code as string literals in English. We want to translate these error messages into German. What would be the best way to approach this? Leave the string literals as-is, and map the char* to another language inside the erro...
hi i want to convert a string literal in to string value, can any one guide me in doing that for eg i want o convert the following string literal in to stringvalue. "hello \r\n world" in to "hello world" ...
I'm having difficulties parsing filepaths sent as arguments: If I type: os.path.normpath('D:\Data2\090925') I get 'D:\\Data2\x0090925' Obviously the \0 in the folder name is upsetting the formatting. I can correct it with the following: os.path.normpath(r'D:\Data2\090925') which gives 'D:\\Data2\\090925' My problem is, how d...
If I call a function like myObj.setType("fluid"); many times in a program, how many copies of the literal "fluid" are saved in memory? Can the compiler recognize that this literal is already defined and just reference it again? ...
I'm experimenting to learn flex and would like to match string literals. My code currently looks like: "\""([^\n\"\\]*(\\[.\n])*)*"\"" {/*matches string-literal*/;} I've been struggling with variations for an hour or so and can't get it working the way it should. I'm essentially hoping to match a string literal that can't conta...
Is it possible to create a constructor (or function signature, for that matter) that only accepts a string literal, but not an e.g. char const *? Is it possible to have two overloads that can distinguish between string literals and char const *? C++ 0x would kind-of allow this with a custom suffix - but I'm looking for an "earlier" sol...
Greetings, I'm sure that this is probably an incredibly stupid question, but... What does the following line actually do? string = @"Some text"; Assuming that "string" is declared thusly in the header: NSString *string; What does the "=" actually do here? What does it do to "string"'s reference count? In particular, assuming th...
I'm referring to the syntax for writing strings in code, including multiline strings and verbatim strings. (Context: I'm working on a tool that scans code, and it's important to determine when tokens are inside a string.) Thanks! ...
Like in: u'Hello' My guess is that it indicates "unicode", is it correct? If so, since when is it available? ...
In c# and ruby and many other languages you can denote a string as to not need escaping. in c# its like this string s = @"\whatever\this\is"; the results are when printed \whatever\this\is my question is, is this supported in any form in javascript? ...
