I’ve renamed inkpdf to Press (as in printing press).

I reached the point where creating the PDF manually is no longer feasible, so I’ve been working on getting Press to a point where I can implement the PDF generation. The basic structure is in place, sans the PDF part. (That’s next.)

Here’s what a Press script looks like right now:

from press import Press

p = Press('output.pdf', width=6*Press.INCH, height=11*Press.INCH,
          margin=1*Press.INCH)

# Horizontal borders at top and bottom of page
p.stroke('#000')
p.pen(1.0)
p.line(p.page_min_x, p.page_min_y, p.page_max_x, p.page_min_y)
p.line(p.page_max_x, p.page_min_y, p.page_max_x, p.page_max_y)

# Page 2
p.page(2)
p.layer('base')
p.stroke(rgb=(1, 0, 0))
p.line(150, 150, 300, 300)
p.layer('fg')
p.stroke(hsl=(0, 0.5, 0.8))
p.line(300, 300, 450, 150)

# Go back and add another line to page 1
p.page(1)
p.stroke('#025')
p.line(p.page_min_x, p.page_min_y, p.page_min_x, p.page_max_y)

p.save() # this doesn't work yet

You can also do something like this:

with Press('output2.pdf', size=Press.LETTER,
           margin=(0.5*Press.INCH, 1.0*Press.INCH),
           inner_margin=0.5*Press.INCH,
           outer_margin=1.25*Press.INCH,
           bleed=.125*Press.INCH) as p:
    p.line(50, 50, 250, 50)
    # And so on

(Context manager, inner/outer margin, bleed, built-in paper sizes.)

Up next: adding more primitives, designing the font selection mechanism, getting it to generate an actual PDF, embedding fonts, using arbitrary Unicode code points, integrating HarfBuzz, etc.
