One of my nerdy colleagues, @mattcaldwell, just gave a neat presentation at a Django-District Meetup on using vim+tmux as Django IDE. To keep it real, he created his presentation using vimdeck and actually presented his slides inside of vim.
I figured it would annoy him to no end to see his presentation in PowerPoint format. So here's a script to do it...
#!/usr/bin/python
# -*- coding: utf-8 -*-
import os
import sys
from cStringIO import StringIO
from argparse import ArgumentParser
from pptx import Presentation
from pptx.enum.shapes import MSO_SHAPE
from pptx.dml.color import RGBColor
from pptx.util import Inches, Pt
def is_md(src, f):
"""Returns true if file exists and has a Markdown extension"""
return os.path.isfile(os.path.join(src, f)) and f.endswith('.md')
def get_pages(src):
"""Returns a list of Markdown filenames in the source directory."""
return [os.path.join(src, f) for f in os.listdir(src) if is_md(src, f)]
def build_deck(pages):
"""Returns the actual PowerPoint deck."""
pres = Presentation()
blank_slidelayout = pres.slide_layouts[6]
for page in pages:
slide = pres.slides.add_slide(blank_slidelayout)
left = top = Inches(0)
width = Inches(10)
height = Inches(5.63)
shape = slide.shapes.add_shape(MSO_SHAPE.RECTANGLE, left, top, width,
height)
shape.fill.solid()
shape.fill.fore_color.rgb = RGBColor(0, 0, 0)
textbox = slide.shapes.add_textbox(left, top, width, height)
textframe = textbox.text_frame
para = textframe.paragraphs[0]
run = para.add_run()
run.font.name = "Consolas"
run.font.size = Pt(7)
run.font.color.rgb = RGBColor(255, 255, 255)
f = open(page)
run.text = f.read()
f.close()
return pres
if __name__ == '__main__':
parser = ArgumentParser(
description='My dorky colleague created a presentation using vimdeck.\
The very last thing he would want to see is it as a real\
PowerPoint deck. So here you go...',
epilog='This thing returns binary data, so you probably want to pipe\
the output to a file with a .pptx extension. Oh, and be sure\
to "pip install python-pptx" first.')
parser.add_argument('source', type=str, nargs=1, help='Path to source\
directory containing vimdeck markdown files.')
args = parser.parse_args()
source = os.path.realpath(args.source[0])
deck = build_deck(get_pages(source))
output = StringIO()
deck.save(output)
sys.stdout.write(output.getvalue())
output.close()
sys.exit()
Or grab the Gist. The
only Python dependency is pptx. pip install python-pptx
will do just fine. For me, this was really just a fun exercise to gain a
better understanding of the pptx library. (note: this example was tested
against python-pptx==0.5.7)
