Glob Patterns

jEdit uses glob patterns similar to those in the various Unix shells to implement file name filters in the file system browser. Glob patterns resemble regular expressions somewhat, but have a much simpler syntax. The following character sequences have special meaning within a glob pattern:

  • ? matches any one character
  • * matches any number of characters
  • {!glob} Matches anything that does not match glob
  • {a,b,c} matches any one of a, b or c
  • [abc] matches any character in the set a, b or c
  • [^abc] matches any character not in the set a, b or c
  • [a-z] matches any character in the range a to z, inclusive. A leading or trailing dash will be interpreted literally

In addition to the above, a number of "character class expressions" may be used as well:

  • [[:alnum:]] matches any alphanumeric character
  • [[:alpha:]] matches any alphabetical character
  • [[:blank:]] matches a space or horizontal tab
  • [[:cntrl:]] matches a control character
  • [[:digit:]] matches a decimal digit
  • [[:graph:]] matches a non-space, non-control character
  • [[:lower:]] matches a lowercase letter
  • [[:print:]] same as [:graph:], but also space and tab
  • [[:punct:]] matches a punctuation character
  • [[:space:]] matches any whitespace character, including newlines
  • [[:upper:]] matches an uppercase letter
  • [[:xdigit:]] matches a valid hexadecimal digit

Here are some examples of glob patterns:

  • * – all files
  • *.java – all files whose names end with ".java"
  • *.{c,h} – all files whose names end with either ".c" or ".h"
  • *[^~] – all files whose names do not end with "~"

 Regular Expressions

jEdit uses regular expressions to implement inexact search and replace. A regular expression consists of a string where some characters are given special meaning with regard to pattern matching.

Within a regular expression, the following characters have special meaning:

Positional Operators

  • ^ matches at the beginning of a line
  • $ matches at the end of a line
  • \b matches at a word break
  • \B matches at a non-word break
  • \< matches at the start of a word
  • \> matches at the end of a word

One-Character Operators

  • . matches any single character
  • \d matches any decimal digit
  • \D matches any non-digit
  • \n matches the newline character
  • \s matches any whitespace character
  • \S matches any non-whitespace character
  • \t matches a horizontal tab character
  • \w matches any word (alphanumeric) character
  • \W matches any non-word (alphanumeric) character
  • \\ matches the backslash ("\") character

Character Class Operator

  • [abc] matches any character in the set a, b or c
  • [^abc] matches any character not in the set a, b or c
  • [a-z] matches any character in the range a to z, inclusive. A leading or trailing dash will be interpreted literally
  • [[:alnum:]] matches any alphanumeric character
  • [[:alpha:]] matches any alphabetical character
  • [[:blank:]] matches a space or horizontal tab
  • [[:cntrl:]] matches a control character
  • [[:digit:]] matches a decimal digit
  • [[:graph:]] matches a non-space, non-control character
  • [[:lower:]] matches a lowercase letter
  • [[:print:]] same as [:graph:], but also space and tab
  • [[:punct:]] matches a punctuation character
  • [[:space:]] matches any whitespace character, including newlines
  • [[:upper:]] matches an uppercase letter
  • [[:xdigit:]] matches a valid hexadecimal digit

Subexpressions and Backreferences

  • (abc) matches whatever the expression abc would match, and saves it as a subexpression. Also used for grouping
  • (?:...) pure grouping operator, does not save contents
  • (?#...) embedded comment, ignored by engine
  • (?=...) positive lookahead; the regular expression will match if the text in the brackets matches, but that text will not be considered part of the match
  • (?!...) negative lookahead; the regular expression will match if the text in the brackets does not match, and that text will not be considered part of the match
  • \n where 0 < n < 10, matches the same thing the nth subexpression matched. Can only be used in the search string
  • $n where 0 < n < 10, substituted with the text matched by the nth subexpression. Can only be used in the replacement string

Branching (Alternation) Operator

  • a|b matches whatever the expression a would match, or whatever the expression b would match.

Repeating Operators

These symbols operate on the previous atomic expression.

  • ? matches the preceding expression or the null string
  • * matches the null string or any number of repetitions of the preceding expression
  • + matches one or more repetitions of the preceding expression
  • {m} matches exactly m repetitions of the one-character expression
  • {m,n} matches between m and n repetitions of the preceding expression, inclusive
  • {m,} matches m or more repetitions of the preceding expression

Stingy (Minimal) Matching

If a repeating operator (above) is immediately followed by a ?, the repeating operator will stop at the smallest number of repetitions that can complete the rest of the match.
