lolcat.nim

lolcat implemented with nim It's a simple program I made to learn the Nim language

• Fast and with no dependencies (compiles to C)
• Handles lines with terminal width and EOL
• Always uses truecolor
• Animates text print

Comparison

Here is a comparison of lolcat versions running time dmesg | lolcat

lolcat edition	real time	user time	sys time	correct line ending	implemented in
lolcat.nim	0,289s	0,152s	0,102s	yes	Nim
clolcat	0,055s	0,019s	0,043s	no	C

Even with my little experience and probably not the best implementation, Nim shows an impressive speed in comparison with pure C.

The original Ruby version wasn't tested, but in other comparisons it's 10x slower than the C version, while my Nim version is just 5x.

Of course, that's all in my computer, the times may vary.
