hgignore - syntax for Mercurial ignore files
The Mercurial system uses a file called .hgignore in the root directory
of a repository to control its behavior when it finds files that it is
not currently managing.
Mercurial ignores every unmanaged file that matches any pattern in an
ignore file. The patterns in an ignore file do not apply to files
managed by Mercurial. To control Mercurial's handling of files that it
manages, see the hg(1) man page. Look for the "-I" and "-X" options.
In addition, a Mercurial configuration file can point to a set of
per-user or global ignore files. See the hgrc(5) man page for details
of how to configure these files. Look for the "ignore" entry in the
An ignore file is a plain text file consisting of a list of patterns,
with one pattern per line. Empty lines are skipped. The "#" character
is treated as a comment character, and the "\" character is treated as
an escape character.
Mercurial supports several pattern syntaxes. The default syntax used is
Python/Perl-style regular expressions.
To change the syntax used, use a line of the following form:
where NAME is one of the following:
Regular expression, Python/Perl syntax.
The chosen syntax stays in effect when parsing all patterns that
follow, until another syntax is selected.
Neither glob nor regexp patterns are rooted. A glob-syntax pattern of
the form "*.c" will match a file ending in ".c" in any directory, and a
regexp pattern of the form "\.c$" will do the same. To root a regexp
pattern, start it with "^".
Here is an example ignore file.
# use glob syntax.
# switch to regexp syntax.
