HelloWorlder
A very specialized programming language that only prints "Hello World!"
Installation
$ cd build
$ ../configure
$ make
$ sudo make install
Usage
A HelloWorlder program can just and only print "Hello World!". So the language was optimized for this task: there are no statements, commands or even comments. Anything beyond an empty source file is considered a syntax error.
So this is how you create and run your first HelloWorlder program:
$ touch my-first-hello-worlder
$ helloworlder my-first-hello-worlder
Hello World!
$
Are there other languages whose recommended editor is touch
?
But it does not stop there. You can use no editor:
$ helloworlder never-written-hello-worlder-source-file
Hello World!
$
or even:
$ helloworlder /dev/null
Hello World!
$
Notice the interpreter is very strict about syntax:
$ helloworlder /dev/random
Syntax error: Unexpected statement
$
Uninstalling
$ cd build
$ sudo make uninstall
But... Why?!
Because I stumbled upon this bad meme attempt (yeah, there are syntax errors):
Apparently claiming that we should evaluate languages on how verbose is "Hello World!" on them.
Well then... now you have the least verbose language, that ONLY prints "Hello World!"!
