Recently I’ve switched to proportional fonts for programming, and have been looking for font choices, but find I’m missing some vocabulary.
There was a post on variable width fonts for coding here: http://typophile.com/node/13090
But aside from a few choices, I couldn't glean how to look for good fonts.
Here are the characteristics I’m looking for:
0 - The font needs to work well at small sizes and coarse resolutions.
1 - The lowercase L and number 1, as well as capital i, need to be distinct at small sizes. Same with zero and o (upper and lowercase).
2 - Punctuation needs to be prominent. A period and a comma mustn’t be confused. Same with primes and hatches. (Helvetica and Fira Sans crash and burn here).
