These are things I have picked up from 18 years in the industry.
Let me comment some of it then …
camelCase
use prefixes
prefixes should be one word followed by an underscore.
Highly depends on your environment, your naming convention, etc.
functions should be prefixed with the file in which they’re defined
In modern day programming the file names are pretty much irrelevant. All somewhat recent programming languages have modules and namespaces. I don’t care in what file fooBar was defined. ALso: what happens if you refactor stuff and rename the file? Do you want to go through everything where the function is mentioned? (This can be automated, though, but still.)
Start Bools with is
Or with whatever is the naming convention you or your team follows. I do embedded scripting and one of the projects explicitly wants can_verb_thing when it comes to user permissions (can_change_foobar, can_run_baz, etc.). It is a good advice but heavily depends on your environment.
start output with _
Paraphrasing the naming convention I mostly work with: Start everything with _ that will be exported to global namespace. Also use the name of your module. Instead of foobar use _mymodule_foobar.
Globals should be g_VARIABLENAME
Globals should be properly namespaced to global context. constants are uppercase.
calc_ImportantValueThatWillDecideTheUsersView is better than calc_SumYears
And summarizeYears is even better. Do not use abbreviations and describe what the function does. If it summarizes the years there is no need to name it something else. Document your code (in-code documentation as well as user-facing documentation if applicable).
I appreciate your emacs perspective, thanks for the input.
I get the sense that programmerhumor hates prefixes, but I’m telling you, they have changed my life. Next project-for-fun, just give it a try and see what happens. I think you’ll be surprised.
To many of your points, I say I agree that a lot of naming conventions depend on context. The environment you’re working in, the IDE, the team you’re working on, the language you’re coding in.
However, prefixes I’m firm on. I think it’s unpopular because it’s from a bygone era where IDEs were non-existent. And while yes, ides have replaced many of the uses, they have been the most radical change to my readability and comprehension of the code I’ve written.
Also, I’m mostly a js programmer, so yes, very different from emacs.
Also, for calc_SumYears, I literally meant to add the years together, hense the prefix. So, maybe the prefixes are a little more useful than you give them credit.
