Glob-like file and pattern matching utility.
Requirements
- PHP >= 7.2
Installation
Install Splat with Composer.
composer require phlak/splat
Then import the Glob
or Pattern
classes as needed.
use PHLAK\Splat\Glob;
use PHLAK\Splat\Pattern;
Patterns
Glob
methods accept a $pattern
as the first parameter. This can be a string or an instance of \PHLAK\Splat\Pattern
.
$pattern = new Pattern(...);
$pattern = Pattern::make(...);
A pattern string may contain one or more of the following special matching expressions.
Matching Expressions
?
matches any single character*
matches zero or more characters excluding/
(\
on Windows)**
matches zero or more characters including/
(\
on Windows)[abc]
matches a single character from the set (i.e.a
,b
orc
)[a-c]
matches a single character in the range (i.e.a
,b
orc
)[^abc]
matches any character not in the set (i.e. nota
,b
orc
)[^a-c]
matches any character not in the range (i.e. nota
,b
orc
){foo,bar,baz}
matches any pattern in the set (i.e.foo
,bar
orbaz
)- Sets may contain other matching patterns (i.e.
{foo,ba[rz]}
)
- Sets may contain other matching patterns (i.e.
Assertions
The following assertions can be use to assert that a string is followed by, or not followed by, another pattern.
(=foo)
matches any string that also containsfoo
(!foo)
matches any string that does not also containfoo
For example, a pattern of *.tar(!.{gz,xz})
will match a string ending with .tar
or .tar.bz
but not tar.gz
or tar.xz
.
Converting Patterns To Regular Expressions
Glob patterns can be converted to a regular expression pattern.
Pattern::make('foo')->toRegex(); // Returns '#^foo$#'
Pattern::make('foo/bar.txt')->toRegex(); // Returns '#^foo/bar\.txt$#'
Pattern::make('file.{yml,yaml}')->toRegex(); // Returns '#^file\.(yml|yaml)$#'
You can control regular expression line anchors via the $options
parameter.
Pattern::make('foo')->toRegex(Glob::NO_ANCHORS); // Returns '#foo#'
Pattern::make('foo')->toRegex(Glob::START_ANCHOR); // Returns '#^foo#'
Pattern::make('foo')->toRegex(Glob::END_ANCHOR); // Returns '#foo$#'
Pattern::make('foo')->toRegex(Glob::BOTH_ANCHORS); // Returns '#^foo$#'
Pattern::make('foo')->toRegex(Glob::START_ANCHOR | Glob::END_ANCHOR); // Returns '#^foo$#'
Pattern Character Escaping
Sometimes you may have characters in a string that shouldn't be treated as matching expression characters. In those situations you can escape any character by preceeding it with a backslash (\
).
Pattern::make('What is happening\?');
Pattern::make('Wall-E \[2008\].mp4');
You may also escape glob pattern characters from a string programmatically with the Pattern::escape()
method.
Pattern::escape('What is happening?'); // Returns 'What is happening\?'
Pattern::escape('*.{yml,yaml}'); // Returns '\*.\{yml\,yaml\}'
Pattern::escape('[Ss]pl*t.txt'); // Returns '\[Ss\]pl\*t.txt'
Methods
Files In
Get a list of files in a directory matching a glob pattern.
Glob::in('**.txt', 'some/file/path');
Returns a Symfony Finder Component containing the files matching the glob pattern within the specified directory (e.g. foo.txt
, foo/bar.txt
, foo/bar/baz.txt
, etc.).
Exact Match
Test if a string matches a glob pattern.
Glob::match('*.txt', 'foo.txt'); // true
Glob::match('*.txt', 'foo.log'); // false
Match Start
Test if a string starts with a glob pattern.
Glob::matchStart('foo/*', 'foo/bar.txt'); // true
Glob::matchStart('foo/*', 'bar/foo.txt'); // false
Match End
Test if a string ends with a glob pattern.
Glob::matchEnd('**.txt', 'foo/bar.txt'); // true
Glob::matchEnd('**.txt', 'foo/bar.log'); // false
Match Within
Test if a string contains a glob pattern.
Glob::matchWithin('bar', 'foo/bar/baz.txt'); // true
Glob::matchWithin('bar', 'foo/baz/qux.txt'); // false
Filter an Array (of Strings)
Filter an array of strings to values matching a glob pattern.
Glob::filter('**.txt', [
'foo', 'foo.txt', 'bar.zip', 'foo/bar.png', 'foo/bar.txt',
]);
// Returns ['foo.txt', 'foo/bar.txt']
Reject an Array (of Strings)
Filter an array of strings to values not matching a glob pattern.
Glob::reject('**.txt', [
'foo', 'foo.txt', 'bar.zip', 'foo/bar.png', 'foo/bar.txt',
]);
// Returns ['foo', 'bar.zip', 'foo/bar.png']
