monospaci.py is a Python script utilizing Fontforge, ttftable, and [ttfautohint] (http://www.freetype.org/ttfautohint/) to scale ordinary variable-width fonts to fixed-width suitable for programming in IDE:s, text editors or terminal emulators.
Originally this script was created due to the authors favour of Serif:ed fonts and the general lack of such high quality Serif:ed fonts (there are like three of them), and a bazillion of Monospace Sans fonts. Thus this script became a biproduct of trying to making the venerable Computer Modern fit into a Terminal.
Lowercase letters are kept as-is (with the exceptions of m and w). Uppercase letters are re-scaled in width to fit the lower case ones. The re-scaling works somewhat, due to most text being lowercase, and most lowercase letters having the same width (with the notable exception of i,j,w, and m).
The kerning may get slightly off, but I haven't been bothered by this much, also uppercase letters can get quite badly scaled (note 'Q' in Garamond below, 'M', and 'W' may in some cases get too thin lines.
Some examples below, do note that the depicted fonts aren't available from here, but easily re-created from the linked Original sources:
JUnicode, excellent for studying old languages. (Original)
Sniglet Mono, when your vim needs more kittens. (Original)
EB Garamond Mono, when your C++ isn't classy enough (Original)
Fifth Leg Mono, thinking inside the box with Python (Original)
Comic Sans MS Mono, really makes your Java pop!
