Why use monospace fonts in your IDE?ide
I've never even considered coding in a proportional font before. So in the interests of science I just switched my editor over to give it a go.
Here are a few observations after fixing a couple of easy tickets:
- Code seems extremely dense. Most of my code is around 80 columns, rarely over 100. A proportional fonts squishes it down to a tiny strip on the left hand side of my editor. Maybe useful if you're short screen space, but it seems unnecessarily compact.
- The 'texture' of the code is lost. It's hard to tell what kind of structure I'm looking at - it's just a big slab of text that needs to be read almost character-by-character.
- It's very easy to miss the
if (!foo). (if (!foo), see!)
- Punctuation characters are very badly defined. Many are hard to tell apart (
- Some punctuation characters are much larger than others, inferring emphasis where none is intended (
- Some characters are very narrow, and very hard to identify (
- Some numbers and letters are very similar (
0Oo iIlvs 0Oo iIl)
- I am extremely reliant on syntax highlighting, without it it's nearly impossible to do things like confirm quotes are balanced, etc.
- Alignment (apart from simple indenting) is completely broken. You can sort of wing it by throwing in extra spaces, but because of the proportional nature of the fonts, the lines may not line up exactly - code looks messier.
- Regular expressions are.. interesting!
There are some positive points, though. Admittedly I've only been using it for a little while, but there are certainly some aspects that work a little better with proportional fonts:
- 'words' are easier to read - spelling errors (eg spelling a variable incorrectly) jump out at you.
- I feel better about using longer, more descriptive variable names (maybe because they scan better, maybe because the horizontal size of the text is compressed)
- It seems slightly easier to read code like this. It's easier for my brain to 'tokenise' each word and understand its meaning. Although because the punctuation characters are harder to read it's still hard going - but maybe that will change given a bit of time to get used to it
I'll update this answer again tomorrow (assuming I can make it through an entire day like this!)
I've seen a couple of font topics on SO and it seems a majority of people use monospace fonts for programming tasks. I have been using Verdana for programming for a couple of years and I really like the enhanced readability, without missing anything monospace related.
Why do you use a monospace font?
Why do we use fixed-width fonts in our IDEs?
ask those guys.
It greatly enhances readability - expecially of punctuation characters which have a very important role in code and which variable width fonts often "squeeze" into minimal space.
