How to convert a number to a string? #52

Closed denilsonsa closed 9 years ago

denilsonsa commented 9 years ago

I'm trying to generate a list of filenames from numbers, but I'm failing to convert a number to a string.

This is obviously wrong: [ "foo" ++ [row] ++ ".png" :: row <- [0..2] ]

$ nip2 --version

Installed on Ubuntu 15.04 using apt-get. I see a new libvips and nip2 version is available, it would be great to have them on Debian/Ubuntu.

Hi, print is a built-in which converts anything to a string. For example:

["hello " ++ print x :: x <- [1..]]
