Although a little more convoluted than I would like, another solution is to use the Chars iterator and its position() function: “Program”.chars().position(|c| c == ‘g’).unwrap() find used in the accepted solution returns the byte offset and not necessarily the index of the character. It works fine with basic ASCII strings, such as the one in … Read more
It appears that StaticString can hold string literals. You can’t assign a variable of type String to it, and it can’t be mutated (with +=, for example). “Knowable at compile time” doesn’t mean that the value held by the variable will be determined at compile time, just that any value assigned to it is known … Read more
Looking at the text package, I see a module called Data.Text.Read. It seems to work: λ> decimal (T.pack “99 bottles”) Right (99,” bottles”) λ> decimal (T.pack “a digit”) Left “input does not start with a digit”
In the debugging console you can get the string value by doing something like: (gdb) print (void)CFShow(myCFString) or: (gdb) po (NSString*)myCFString Either of those will display the entire string’s contents to the debugging console. It’s probably the easiest way to deal with large, variable-length strings or data structures of any kind. For more information, the … Read more
You can’t simply convert []interface{} to []string even if all the values are of concrete type string, because those 2 types have different memory layout / representation. For details see Cannot convert []string to []interface {}. You have to define how you want values of different types to be represented by string values. The easiest … Read more
Probably because String?.plus(Any?) is the only plus function which accepts a nullable type as a receiver in Kotlin library. Therefore, when you call null + null, the compiler will treat the first null as String?. If you define an extension function where the receiver type is Int? and the return type is Int, then x … Read more
Well, you can’t nest ${var%}/${var#} operations, so you’ll have to use temporary variable. Like here: var=”http://whatever/score/” temp_var=”${var#http://}” echo “${temp_var%/score/}” Alternatively, you can use regular expressions with (for example) sed: some_variable=”$( echo “$var” | sed -e ‘s#^http://##; s#/score/$##’ )”
why did not delphi give any error saying the length is beyond 255 for myExtremlyLongString? You have your answer a bit down in the text in section Long String (AnsiString). In current versions of Delphi, the string type is simply an alias for AnsiString, So string is not limited to 255 characters but a string … Read more
If you must do this parsing, I’m sure you’ll get lots of good suggestions here. My suggestion is – don’t do this parsing. Instead, create your input fields so that the information is already separated out. Have separate fields for title, first name, middle initial, last name, suffix, etc.
