The Subversion runtime configuration system provides an option, global-ignores , whose value is a whitespace-delimited collection of file patterns also known as globs.
The Subversion client checks these patterns against the names of the files which are candidates for addition to version control, as well as to unversioned files which the svn status command notices. If any file's name matches one of the patterns, Subversion will basically act as if the file didn't exist at all. When found on a versioned directory, the svn:ignore property is expected to contain a list of newline-delimited file patterns which Subversion should use to determine ignorable objects in that same directory.
These patterns do not override those found in the global-ignores runtime configuration option, but are instead appended to that list. And it's worth noting again that, unlike the global-ignores option, the patterns found in the svn:ignore property apply only to the directory on which that property is set, and not to any of its subdirectories.
The svn:ignore property is a good way to tell Subversion to ignore files that are likely to be present in every user's working copy of that directory, such as compiler output or—to use an example more appropriate to this book—the HTML, PDF, or PostScript files generated as the result of a conversion of some source DocBook XML files to a more legible output format.
Subversion's support for ignorable file patterns extends only to the one-time process of adding unversioned files and directories to version control. Once an object is under Subversion's control, the ignore pattern mechanisms no longer apply to it. In other words, don't expect Subversion to avoid committing changes you've made to a versioned file simply because that file's name matches an ignore pattern—Subversion always notices all of its versioned objects.
The Subversion svn:ignore property is very similar in syntax and function to the CVS. In fact, if you are migrating a CVS working copy to Subversion, you can directly migrate the ignore patterns by using the. There are, however, some differences in the ways that CVS and Subversion handle ignore patterns. The two systems use the ignore patterns at some different times, and there are slight discrepancies in what the ignore patterns apply to.
Also, Subversion does not recognize the use of the! The global list of ignore patterns tends to be more a matter of personal taste, and tied more closely to a user's particular tool chain than to the details of any particular working copy's needs. The following characters have special meaning:. Matches any string of characters, including the empty string no characters. Matches any one of the characters enclosed in the square brackets. For example [AGm-p] matches any one of A , G , m , n , o or p.
Pattern matching is case sensitive, which can cause problems on Windows. You can force case insensitivity the hard way by pairing characters, e. If you want an official definition for globbing, you can find it in the IEEE specifications for the shell command language Pattern Matching Notation. You should not include path information in your pattern.
The pattern matching is intended to be used against plain file names and folder names. If you want to ignore all tmp folders when they exist within a prog folder but not within a doc folder you should use the svn:ignore property instead.
There is no reliable way to achieve this using global ignore patterns. Daily Use Guide Next.
