Tarmo's ascii printing language, 47 bytes.
1 /\| /_/\|/__\_\2 \__|/ 0n{n-a-1{½1}1a{2#1}$} Just by looking to such odd programming languages like CJam, it's makes me bit dizzy how complex, unnatural and cryptic language can be, that I wanted to "boldly go where no man has gone before", and invent my own language. As a result I've created my own language for ascii patterns printing.
Basic idea is that you can define first patten and then printing - using same kind of character '1' or '2' or whatever number - you can define your own print pattern.
Once pattern is defined (Starts from number till number end) - next numbers will execute pattern printing.
For example
1 /\| /_/\|/__\_\01 Outputs like this:
/\ /_/\ /__\_\ Will define pattern 1 and then print it right away. Pattern is defined everything separated with '|' character. 0 at the end - acts like pattern termination.
Special characters like '$' are reserved as line-feed, and '½' is reserved for spacing - half - of specific pattern.
1 /\| /_/\|/__\_\01$½11$½1½11 Will outputs text like this:
/\ /_/\ /__\_\ /\ /_/\ /__\_\ /\ /_/\ /__\_\ Next goes for-loops. That one needs to be easily visible - so I've retained {} brackets for for-loops, but variable names are auto-named - so first bracket will use 'a' variable, second 'b' and so on. Iteration will go always from 0 to specific number - and that number is defined before {} brackets.
'n' is reserved variable for whole function input.
So code:
1 /\| /_/\|/__\_\0n{1$} Will outputs ( With n == 4 ):
/\ /_/\ /__\_\ /\ /_/\ /__\_\ /\ /_/\ /__\_\ /\ /_/\ /__\_\ And '#' is special modifier for trim lead whitespace.
And finally whole solution:
