# File Name Glob Patterns


A [glob pattern][glob] is a text expression that matches one or more
file names using wild cards familiar to most users of a command line.
For example, `*` is a glob that matches any name at all and
`Readme.txt` is a glob that matches exactly one file. 

Note that although both are notations for describing patterns in text,
glob patterns are not the same thing as a [regular expression or
regexp][regexp].

A number of fossil setting values hold one or more file glob patterns
that will identify files needing special treatment.  Glob patterns are
also accepted in options to certain commands as well as query
parameters to certain pages.

In many cases more than one glob may be specified in a setting,
option, or query parameter by listing multiple globs separated by a
comma or white space.


Of course, many fossil commands also accept lists of files to act on,
and those also may be specified with globs. Although those glob
patterns are similar to what is described here, they are not defined
by fossil, but rather by the conventions of the operating system in
use.

    [^...]  Matches one character not in the enclosed list.

Special character sequences have some additional features: 

 *  A range of characters may be specified with `-`, so `[a-d]` matches
    exactly the same characters as `[abcd]`. Ranges reflect Unicode
    code points without any locale-specific collation sequence.

 *  Include `-` in a list by placing it last, just before the `]`.

 *  Include `]` in a list by making the first character after the `[` or
    `[^`. At any other place, `]` ends the list. 

 *  Include `^` in a list by placing anywhere except first after the
    `[`.

 *  Some examples of character lists: 
    `[a-d]` Matches any one of `a`, `b`, `c`, or `d` but not `ä`;
    `[^a-d]` Matches exactly one character other than `a`, `b`, `c`,
    or `d`; 
    `[0-9a-fA-F]` Matches exactly one hexadecimal digit;
    `[a-]` Matches either `a` or `-`;
    `[][]` Matches either `]` or `[`;
    `[^]]` Matches exactly one character other than `]`;
    `[]^]` Matches either `]` or `^`; and
    `[^-]` Matches exactly one character other than `-`.

    Beware that ranges in lists may include more than you expect: 
    `[A-z]` Matches `A` and `Z`, but also matches `a` and some less
    obvious characters such as `[`, `\`, and `]` with code point
    values between `Z` and `a`.

    Beware that a range must be specified from low value to high
    value: `[z-a]` does not match any character at all, preventing the
    entire glob from matching.

 *  Note that unlike typical Unix shell globs, wildcards (`*`, `?`,
    and character lists) are allowed to match `/` directory
    separators as well as the initial `.` in the name of a hidden
    file or directory.


White space means the ASCII characters TAB, LF, VT, FF, CR, and SPACE.

### Commands that Refer to Globs

Many of the commands that respect the settings containing globs have
options to override some or all of the settings. These options are
usually named to correspond to the setting they override, such as
`--ignore` to override the `ignore-glob` setting. These commands are:

 * [`add`][]
 * [`addremove`][]
 * [`changes`][]
 * [`clean`][]
 * [`extras`][]
 * [`merge`][]
 * [`settings`][] 
 * [`status`][]
 * [`unset`][]

The commands [`tarball`][] and [`zip`][] produce compressed archives of a
specific checkin. They may be further restricted by options that
specify glob patterns that name files to include or exclude rather
than archiving the entire checkin.

The commands [`http`][], [`cgi`][], [`server`][], and [`ui`][] that
implement or support with web servers provide a mechanism to name some
files to serve with static content where a list of glob patterns
specifies what content may be served.

[`add`]: /help?cmd=add
[`addremove`]: /help?cmd=addremove
[`changes`]: /help?cmd=changes
[`clean`]: /help?cmd=clean
[`extras`]: /help?cmd=extras
[`merge`]: /help?cmd=merge
[`settings`]: /help?cmd=settings
[`status`]: /help?cmd=status
[`unset`]: /help?cmd=unset

[`tarball`]: /help?cmd=tarball
[`zip`]: /help?cmd=zip

[`http`]: /help?cmd=http
[`cgi`]: /help?cmd=cgi
[`server`]: /help?cmd=server
[`ui`]: /help?cmd=ui


### Web Pages that Refer to Globs



The [`/timeline`][] page supports the query parameter `chng=GLOBLIST` that
names a list of glob patterns defining which files to focus the
timeline on. It also has the query parameters `t=TAG` and `r=TAG` that
names a tag to focus on, which can be configured with `ms=STYLE` to
use a glob pattern to match tag names instead of the default exact
match or a couple of other comparison styles.

The pages [`/tarball`][] and [`/zip`][] generate compressed archives
of a specific checkin. They may be further restricted by query
parameters that specify GLOBs that name files to include or exclude
rather than taking the entire checkin.

[`/timeline`]: /help?cmd=/timeline
[`/tarball`]: /help?cmd=/tarball
[`/zip`]: /help?cmd=/zip


## Platform quirks

The versioned settings files have no platform-specific quirks. Any
GLOBs that matter to your workflow belong there where they can be
safely edited.
