Recently as a result of using Git I've noticed a number of
inconsistencies in the RSpec codebase with respect to whitespace
(mixed line endings, mixed use of spaces and tabs for indentation,
and trailing whitespace at the end of lines). I never would have
noticed, but Git produces nice colorized diff output which highlights
these kinds of inconsistencies.
I wanted to ask if the core RSpec team had established any
conventions/standards for these things. The basic rationale is that
if all contributors agree to a small number of conventions for
whitespace there are less likely to be changesets with non-
substantive whitespace differences (really, false alarms).
The procedure I used to explore this was as follows:
First export a clean copy of the trunk:
svn export svn://rubyforge.org/var/svn/rspec/trunk rspec-trunk
cd rspec-trunk
Then use the following Bash incantation to see which files had UNIX,
Mac or Windows line endings:
IFS="
"
for FILE in $(find . -type f)
do
if ! perl -ne "exit 1 if m/\r/;" "$FILE"; then
echo "CR detected in : $FILE"
else
echo "ok : $FILE"
fi
done
All text files used UNIX line endings (LF) with the exception of
these four, which used Windows line endings (CRLF):
doc/src/default.css
rspec/bin/spec_translator
spec_ui/examples/selenium/README.txt
spec_ui/History.txt
I did a similar Bash thing to find out which files had tabs in them;
many of them appear to consistently use tabs for indentation but some
do not, using a mixture of tabs and spaces.

Finally I did a search for trailing whitespace. Which yielded the
following list. Many of the lines contain nothing but whitespace;
sometimes this use is consistent (ie. the whitespace corresponds to
the nesting level of the current scope) but at other times it is not.
