When comparing Bitstream DejaVu Sans Mono vs Adobe Source Code Pro, the Slant community recommends Adobe Source Code Pro for most people. In the question“What are the best programming fonts?” Adobe Source Code Pro is ranked 2nd while Bitstream DejaVu Sans Mono is ranked 13th. The most important reason people chose Adobe Source Code Pro is:
The characters in Source Code Pro are easily readable. They have consistent widths across all weights as to not break up words. Commonly used programming symbols (such as various kinds of brackets) are made easily discernible from each other while various punctuation marks are made bigger than normal. This makes them especially good for programmers who keep staring at code for hours.
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Very clear distinction between similar characters
It's easy to distinguish between characters such as I, 1, l, O, and 0 in DejaVu Sans Mono.
Pro Clean, readable design
Reading the text is pleasant and effortless. Letter forms combine nicely into words.
Pro It's subtle, yet stylish and extremely readable, very easy on eyes and very effective for long development sessions
Pro Nice uniform spacing
The font is well spaced and doesn't break up words.
Pro Excellent unicode support
DejaVu Sans Mono has one of the most complete Unicode fonts available. This means you have access to a wide range of special symbols including mathematical symbols like arrows, operators, and special alphabets. This is useful for certain languages that require special characters like Agda.
Some languages allow using these characters optionally. There are editor modes that display characters like this without changing the underlying file, much like syntax highlighting. The Emacs modes for OCaml and Haskell are prime examples.
Pro Available with every linux distribution and works fine in vim, emacs and atom
It's also included in modern versions of Windows.
Pro Bold font is the same width as the regular weight font
The Sans Mono version is graphically close to Andale Mono (Microsoft core web font), slightly bolder, with the added bonus of the bold font being the same width as the regular one (unlike Andale Mono). It is a nice property with some syntax highlighting text editors.
Pro Closely related to MobaFont
For MobaXterm users, this font closely mirrors the embedded MobaFont so they can use a monospace font across other applications.
Pro Easy on user's eyes
The characters in Source Code Pro are easily readable. They have consistent widths across all weights as to not break up words. Commonly used programming symbols (such as various kinds of brackets) are made easily discernible from each other while various punctuation marks are made bigger than normal. This makes them especially good for programmers who keep staring at code for hours.
Pro Legible on all displays
The characters have been made in such a way that they are easily discernible and usable regardless of font size, weight, and display.
Pro Free and open source
The font is licensed under SIL open font license with source code available on GitHub. Being an open source font, it's also reasonable to expect incremental upgrades and additions to character sets and functionality.
Pro Even spacing
Characters are evenly spaced, making for better readability.
Pro Great in print
The font works particularly well when it is in print.
Pro Several styles available
The code comes with seven style variants: ExtraLight, Light, Regular, Medium, Semibold, Bold, and Black.
Pro Offers italics
The beta release version of Source Code Pro introduced italicized characters on Jul 18, 2015.
Pro Available with Google Web Fonts
The font is hosted on Google Web Fonts directory, meaning that it can be easily embedded in web pages.
Pro Powerline symbols included
Powerline symbols are useful for programmers to display a nicer status bar or mode-line on Vim and Emacs.
Pro Version with ligature support for Haskell is available
A version of Source Code Pro with support for common Haskell composite glyphs such as >>= is available here. An editor with ligature support, such as Leksah, is required.
Pro Light and Extra Light weights available
The Light and Extra Light weights make the font less "bold" looking when reading.
Cons
Con Crowded bold styles
At size 12, in bold text, some letters bump up against each other too closely, greatly reducing legibility.
Con Tilde character lacks curvature
The tilde character in this font ('~') does not have enough curvature to be read easily at small sizes. This can be a concern for Unix(-like) shell users and script writers, as the tilde is used relatively often compared to other symbols.
Con The "-" symbol is short
For example, when using the '-' symbol for borders, it's super short in this font.
Con No ligatures
Missing programming ligatures.
Con Dotted zero
Dotted zero is less readable than slashed zero.
Con Not suitable for Vietnamese
This font is really ugly when used with Vietnamese characters.
Con Missing some Vietnamese characters
ấ, ề, ự, etc. are missing in DejaVu Sans Mono.
Con Some characters are similar
Small 'L', capital 'i' and 1 are too similar.
Con Too much serif on lowercase L
Lowercase L has a top left serif and a bottom right curved serif, and both are too long; so long that they make lowercase L look like an uppercase i.
Con Dotted zero lacks clarity
Dotted zero characters are less distinct from capital "O" characters than slashed zero characters.
Con Very difficult to read compared to Consolas or Courier New
The characters are much too widely spaced apart to be easily readable.
Con Excessive line spacing
The lines are spaced too far apart.
Con Ligatures missing but you can try Hasklig font if you want ligature
Con Can be somewhat odd for hex numbers with certain styles
With certain font-size and font-weight combinations (12 pt and regular, for example) capital letters are bigger than integer digits, making hex numbers look weird.
Con Incomplete Unicode support
This font is missing many unicode characters used to "beautify" various terminal apps. Also missing are programming ligatures used in some languages.
