Crate str_block

str-block

str_block is a proc macro for processing string literals. It removes the first line from its input if it’s empty except for whitespace, and removes common indentation from the rest of the lines. Lines that are empty except for whitespace are treated as if they have the common indentation.

assert_eq!(str_block! {"
    Hello
    World
"}, "Hello\nWorld\n");

Use with {} to stop rustfmt from moving around your string.

You can pass multiple string literals to str_block, and it’ll concatenate them for you before processing the result. You can also pass raw string literals.
