## NAME

| npiet-foogol - a foogol to piet compiler

## SYNOPSIS

| npiet-foogol [ -v | -d ] [ -w <n> ] [ -b <n> ] inputfile

## DESCRIPTION

| npiet-foogol translates foogol input to a piet program. So npiet-foogol creates a picture from foogol source. The picture is, well should be, a valid piet program and can be executed, eg. by the npiet interpreter.

## OPTIONS

| -h

| print usage help and exit.

| -v

| be somewhat verbose.

| -d

| print debug output (lot's of more or less cryptic and mostly useless blurb).

| -w <n>

| Sets a wrap-width in pixel. This gives the compiler a hint about a block width to use when generating expressions or statements. Usually code is generated left to right until the wrap-width is reached and then to the left. To avoid codel overlaps in loops and conditionals, code is generated with a virtual left border, but this wrap-width too. Here is lot of optimisation possible.

| -b <n>

| Sets the base used by generating a number. The default is 7 and a value greater or equal of 2 is acceptable. In a piet program the number of codels (here pixels) of a color block represents a number. To be able to push a large number on the stack without wasting a lot of ink, the number is calculated and the given base is used to do so.

| -o <filename> Sets the output filename. Default is npiet-foogol.png.

| inputfile

| The foogol program to read. Use a - to read from <stdin>.

## FILES

| npiet-foogol.png - default name of the piet program file to write. It is overwritten if it exists.

## BUGS
