Nesty
A small crate to help generate human readable code from rust.
The primary interface is the code!
macro which looks as follows:
code!{
[0] "fn main() {";
[1] "println!(\"hello, world\");";
[0] "}"
}
The bracketed numbers give the desired amount of indentation for the line.
Code blocks can also be nested, like so:
let if_expr = code!{
[0] "if x > 0 {";
[1] "println(\"found one!\")";
[0] "}"
}
code!{
[0] "fn main() {";
[1] if_expr;
[0] "}"
}
which will produce
fn main() {
if x > 0 {
println!("found one!");
}
}
The code macro also supports strings, and vectors of strings which will be properly indented, (vectors are assumed to be a vector of lines, strings are indented after each newline)
With the diff_assert
feature, the crate also has a assert_same_code
macro
which checks two strings for equality, and if they differ, prints a diff before panicing.
