I will agree, variable naming is very important, but it
really depends upon scope. If i am writing a one-liner,
i'll use the fewest characters possible, such as $f, @f,
or %f. If i am writing a throw away script, i don't feel
quilty for using foo, bar, baz, and qux here and there.
If it is a script that i plan for others to use, i sit
and think very carefully about the names. If i am working
with a group, i will do my best to stick to whatever
standards they have agreed upon.
Coming from Java, i used to name my variables like
employeeRecord and thingWithNoName, but now i stick to the
convention of using all lower case and separating words
with the underscore - thing_with_no_name. This also keeps
me from chosing long names since i hate reaching for the
underscore key. ;)
When confronted with mental block on finding a good name,
if i can't think of one in 5 minutes or less, i will pick
something and move on. Leaving a comment that promises to
rename the variable reminds me of why i did so. I really
feel that names are important, but not so important as to
get stuck in rut over them. This is similar to listening to
someone's conversation when they pause for far too long
trying to find the right word, completely losing
their train of thought.
Final comment - plurals. tye finally convinced me to
avoid using plurals for arrays and hashes, because they
already indicate a colletion: @file, @line, %record. This keeps me from guessing between $file and @file, $record and
%record. This is also a new practice for me, so i sometimes
Consistency is golden
