snake case...

I did it for years in Perl then moved to camel with Java. Now, I sort of like not having to type underscores.

I went the other way. I like it when my code doesn't look like a jumble of random letters with the least important words capitalized.

I went back and forth, both ways. I started out in Python with snake_case identifiers, then moved to Javascript with camelCase, and now I mostly use Rust with snake_case for names and UpperCamelCase for types.

I don't find either style better than the other, the only time I notice anything is when I switch between style conventions (e.g. switch between JS and Rust or C++), because I need to break the habit of typing one way rather than the other.

Still, I find readability of the two styles pretty much identical at all times once you get used to both.

For me it's more about ease in typing. I find typing underscore so many times a bug deterrent in fast typing speed.

My current style convention mixes several naming styles to help in distinguishing code visually.

I prefer camelCase for variables, which need to be typed repeatedly, and camel is fastest to type. I use snake_case for functions, UpperCamelCase for classes/types, and ALL_CAPS_SNAKE for configuration variables a user would be expected to edit.

What language is that in? Conventions tend to follow with programming languages.

In C, snake case is historically the default, but I tend to use UpperCamelCase for functions, UpperCamelCase for file-level static variables, lowerCamelCase for function-level static variables and ALL_CAPS_SNAKE for #defines.

    camel is fastest to type

iAgree but englishIsAlso fasterToType byRemovingSpacesAnd capitalizingFewerWordsThan usual. iDonT knowWhy weProgrammers shouldConsiderThat aWorthwhile tradeOff

In Perl 6, you can also use "kebab-case":

    my $is-it-time = True;

The hyphen is allowed inside an identifier as long as it is not the first and as long as it is followed by at least one letter.

    my $foo-42;  # interpreted as my $foo - 42

This is also the standard for Common Lisp, Scheme, emacs-lisp.
