For fonts, agreed with Luigi, it would be nice to see some lua code that
a) takes a bunch of fonts as input (like:
regular/italic/bold/bolditalic/script) and writes some simple sentence
with all variants; switching options on and off (after thinking a bit,
this can just as well be done in almost-plain-TeX in LuaTeX, so maybe
it's not such a good idea)
b) takes a font as input and makes a really nice graphical representation:
- font name (under different OS systems?), file name, ...
- available features
- glyph repertoire (index/Unicode point/name/big drawing)
- alternatives of the same glyph (under small caps or when alternative
styles play some role), ... [i know it's incomplete]
- ...
- takes some input string and writes out that sentence under different
permutations of available features (with some user's help)
c) shows some OpenType math tricks (visually?) or even does the same
as showttf/poin b, but for math (challenge :) :) :)
One of possible ideas for an advanced example (just brainstorming; you
need to judge whether it makes sense or not; it might be too long &
complicated, but it would be instructive to see both parsing and
drawing at the same time):
- parse some very simple text input
- draw the image with mplib
For example, one could try to parse:
http://www.daylight.com/dayhtml/doc/theory/theory.smiles.html
(but with some strict restrictions, like: no cycles allowed, no
reactions, ... only element names, =, # and parenthesis with at most
one branch; no nested ones)
and then try to draw a full circle for every element and connect the
circles with single/double/triple lines (no attempt for optimal
placement and nothing complicated).
