# From man gitignore 5:
|
||||
# If the pattern ends with a slash, it is removed for the purpose of the
|
||||
# following description, but it would only find a match with
|
||||
# a directory. In other words, foo/ will match a directory foo and paths
|
||||
# underneath it, but will not match a regular file or a symbolic link
|
||||
# foo (this is consistent with the way how pathspec works in general in
|
||||
# git).
|
||||
#
|
||||
# A leading slash matches the beginning of the pathname. For example,
|
||||
# "/*.c" matches "cat-file.c" but not "mozilla-sha1/sha1.c".
|
||||
#
|
||||
# If the pattern does not contain a slash /, git treats it as a shell
|
||||
# glob pattern and checks for a match against the pathname relative to
|
||||
# the location of the .gitignore file (relative to the toplevel of the
|
||||
# work tree if not from a .gitignore file).
|
||||
#
|
||||
# Otherwise, git treats the pattern as a shell glob suitable for
|
||||
# consumption by fnmatch(3) with the FNM_PATHNAME flag: wildcards in the
|
||||
# pattern will not match a / in the pathname. For example,
|
||||
# "Documentation/*.html" matches "Documentation/git.html" but not
|
||||
# "Documentation/ppc/ppc.html" or "tools/perf/Documentation/perf.html".
|
||||
#
|
||||
# If you can't tell what the hell this means you're not alone, because git's
|
||||
# documentation is fucking inscrutable. Here's what I've come up with from
|
||||
# trial and error:
|
||||
#
|
||||
# 0. Patterns ending in a slash will only match directories, and then you
|
||||
# can ignore that slash for the rest of these rules.
|
||||
# 1. Patterns are shell globs, except * doesn't match / and there's no **.
|
||||
# 2. Patterns without a slash search the basename of the path, for example:
|
||||
# the 'file.txt' in '/foo/bar/file.txt'.
|
||||
# 3. Patterns with a slash search against the entire path.
|
||||
# 4. All matching must match the entire string it's searching. For example:
|
||||
#
|
||||
# 'am' will not ignore '/foo/bar/spam'
|
||||
# it matches against the basename 'spam' but does not match all of it
|
||||
#
|
||||
# 'bar/spam' will not ignore '/foo/bar/spam'
|
||||
# it matches against the full path (because it has a slash) but does not
|
||||
# match all of it.
|
||||
# 5. A leading slash doesn't affect the matching, but does turn a
|
||||
# "pattern with no slash" into a "pattern with a slash". So:
|
||||
#
|
||||
# 'bar' will ignore '/foo/bar/spam' (actually it'll ignore bar entirely)
|
||||
# it matches against the basename 'bar' (because there's no slash) when
|
||||
# at that level
|
||||
#
|
||||
# '/bar' will not ignore '/foo/bar/spam'
|
||||
# it matches against the entire path '/foo/bar' (because there is
|
||||
# a slash) when at that level
