getContents
GetContents is a function name used in several programming environments for retrieving the full contents of a source into a single string or buffer. In practice, it often refers to reading an entire input stream, typically standard input, into memory in one operation. The exact behavior and typing depend on the language and library, but the concept remains a convenience for obtaining all input at once rather than iterating line by line.
In Haskell, getContents is a standard IO action with type IO String. It reads from the standard
Common usage in Haskell includes examples such as:
- main = do s <- getContents; putStrLn s
These patterns demonstrate reading all input and either printing it or transforming it with a pure function,
Caveats and considerations include the implications of lazy IO, which can cause space leaks if the program
