gysb is Generate Your Swifty Boilerplate.
Swift implementation of swift/gyb
$ cat TestResources/simple1/a.txt.gysb
Hello 100%%
%{
let y = 10
let x = 42
func succ(_ a: Int) -> Int {
return a + 1
}
}%
I can assure you that ${x} < ${succ(x)}
% if y > 7 {
% for _ in 0..<3 {
y is greater than seven!
% }
% } else {
y is less than or equal to seven
% }
The End.
$ swift run gysb Examples/simple1/a.txt.gysb
Hello 100%
I can assure you that 42 < 43
y is greater than seven!
y is greater than seven!
y is greater than seven!
The End.
