Glob - Extended unix style pathname expansion
Using Glob Patterns
Suppose you want SpaceConsistencyBear
to perform an analysis on a filefirst.c
, you should use the command:
- coala --files=src/first.c --bears=SpaceConsistencyBear --save
Note
If you don’t know the functions of a bear or how to perform the analysiswith a bear, you should go through Tutorial first.
Now, if you want all the .c
files in a specific directory to be analysed,you can take help of glob patterns.
- coala --files='src/*.c' --bears=SpaceConsistencyBear --save
Here, *.c
matches all .c
files in the src
directory.Going further, if you want all .c
as well as .java
files tobe analysed:
- coala --files='src/*.(java|c)' --bears=SpaceConsistencyBear --save
If you want your files
argument to match all directories andsubdirectories, you can use **
glob pattern for that.
- files = **/*.c
Note
While using files = */.c
, since we have used /
in the globpattern, all .c
files at least one subdirectory below the rootdirectory will be matched.
In coala, files and directories are specified by file name. To allowinput of multiple files without requiring a large number of filenames,coala supports a number of wildcards. These are based on the unix-styleglob syntax and they are not the same as regular expressions.
Note
Any glob that does not start with a /
in Linux or a drive letterX:
in Windows will be interpreted as a relative path. Please use commaseparated values instead of absolute path globs that start with aglob expression.
Syntax
The special characters used in shell-style wildcards are:
PATTERN | MEANING |
---|---|
[seq] | Matches any character in seq. Cannot be empty. Anyspecial character loses its special meaning in a set. |
[!seq] | Matches any character not in seq. Cannot be empty. Anyspecial character loses its special meaning in a set. |
(seq_a|seq_b) | Matches either sequence_a or sequence_b as a whole. Morethan two or just one sequence can be given. |
? | Matches any single character. |
| Matches everything but the directory separator. |
* | Matches everything. |
Note
If you’re looking for a negation pattern to exclude paths, check out the—ignore
argument or ignore
.coafile option here.
Examples
[seq]
Matches any character in seq. Cannot be empty. Any special characterloses its special meaning in a set.
Opening and closing brackets can be part of a set, although closingbrackets have to be placed at the first position.
- >>> from coalib.parsing.Globbing import fnmatch
- >>> fnmatch("aaa", "a[abc]a")
- True
- >>> fnmatch("aaa", "a[bcd]a")
- False
- >>> fnmatch("aaa", "a[a]]a")
- False
- >>> fnmatch("aa]a", "a[a]]a")
- True
- >>> fnmatch("aaa", "a[]abc]a")
- True
- >>> fnmatch("aaa", "a[[a]a")
- True
- >>> fnmatch("a[a", "a[[a]a")
- True
- >>> fnmatch("a]a", "a[]]a")
- True
- >>> fnmatch("aa", "a[]a")
- False
- >>> fnmatch("a[]a", "a[]a")
- True
[!seq]
Matches any character not in seq. Cannot be empty. Any specialcharacter loses its special meaning in a set.
- >>> fnmatch("aaa", "a[!a]a")
- False
- >>> fnmatch("aaa", "a[!b]a")
- True
- >>> fnmatch("aaa", "a[b!b]a")
- False
- >>> fnmatch("a!a", "a[b!b]a")
- True
- >>> fnmatch("a!a", "a[!]a")
- False
- >>> fnmatch("a[!]a", "a[!]a")
- True
(seq_a|seq_b)
Matches either sequence_a or sequence_b as a whole. More than twoor just one sequence can be given.
Parentheses cannot be part of an alternative, unless they are escaped bybrackets. Parentheses that have no match are ignored as well as|
-separators that are not inside matching parentheses.
- >>> fnmatch("aXb", "a(X|Y)b")
- True
- >>> fnmatch("aYb", "a(X|Y)b")
- True
- >>> fnmatch("aZb", "a(X|Y)b")
- False
- >>> fnmatch("aXb", "(a(X|Y)b|c)")
- True
- >>> fnmatch("a", "a|b")
- False
- >>> fnmatch("a|b", "a|b")
- True
- >>> fnmatch("(aa", "(a(a|b)")
- True
- >>> fnmatch("a(a", "(a(a|b)")
- False
- >>> fnmatch("a(a", "(a[(]a|b)")
- True
- >>> fnmatch("aa", "a()a")
- True
- >>> fnmatch("", "(abc|)")
- True
?
Matches any single character.
- >>> fnmatch("abc", "a?c")
- True
- >>> fnmatch("abbc", "a?c")
- False
- >>> fnmatch("a/c", "a?c")
- True
- >>> fnmatch("a\\c", "a?c")
- True
- >>> fnmatch("a?c", "a?c")
- True
- >>> fnmatch("ac", "a?c")
- False
*
Matches everything but the directory separator.
Note
The directory separator is platform specific. /
is nevermatched by *
. \
is matched on Linux, but not on Windows.
- >>> fnmatch("abbc", "a*c")
- True
- >>> fnmatch("a/c", "a*c")
- False
- >>> fnmatch("ac", "a*c")
- True
**
Matches everything.
- >>> fnmatch("abbc", "a**c")
- True
- >>> fnmatch("a/c", "a**c")
- True
