I think ligatures can be a great feature, but they should not be decided by the font, but by the editor. So you can can destinguish between 'input >> var' and 'vector<vector<int>>' and render the literature in one case but not the other. This and more creative text decorations can be really helpful to read code. Other examples are rendering css colors inline, rendering of tables and formulas in emacs, ...
- kd5bjo 9y agoThat's a hard one to get right; for a long time, C++ compilers would tokenize 'vector<vector<int>>' incorrectly and throw a syntax error -- the final two angle brackets had to be separated by a space for the code to compile.

- lucideer 9y agoThey aren't implicitly decided by the font, they are supported (or not supported) by the font and explicitly decided by the editor, so your recommendation is the case in practice. i.e. OpenType fonts optionally accept a range of settings flags to toggle various features. For standard ligatures this is the `liga` flag, this flag is off by default and an editor sets the flag to display ligatures (if the particular font supports that flag).
- captainmuon 9y agoReally? That would be nice. Last time I checked, Atom was one of the only editors that supported it anyway, and it just applied ligatures indiscriminately. Same for the terminals that supported ligatures, I don't even know how e.g. vim would signal to a terminal to use a ligature.
