Match () with regex () ()

Information

match with regex block

The match regex block is a reporter block that matches a string with a regular expression, a regex.

Use

This block searches for every instance of the selected rule. The rule can be inserted into the second input box. The third input box acts as a ? (please add what this input box does)

Examples

Foo bar example

Example 1

In this example inputs of the block it searches for the string "foo" in the string "foo bar" which will result in the array ["foo"] since there is only one foo in the string.

Fruit example

Example 2

For this example the block searches for every occurance of the word "banana" which results in the array ["banana","banana","banana"].

Regular expression rule syntax

The rules of regular expressions have their own syntax which you can all look up on this website.

The examples will appear as: [to be matched string] [rule] [third input] -> [result]

Syntax Table

meta characters	Description	Example
.	This is the syntax for any character	["gray grey griy gary"] ["gr.y"] ["g"] -> ["gray", "grey", "griy"]
()	groups a set of characters	No actual change to the result, will be needed later on
+	matches the preceding character or group one or more times	["abbbbbba aba aa"] ["ab+a"] ["g"] -> ["abbbbbba","aba"]
?	matches the preceding character or group zero or one times	["aba aa abba abbbba"] ["a?ba"] ["g"] -> ["aba","aa"]
*	matches the preceding character or group any amount of times	["aba aa abbbbbbbba abbbbbbbbbbbbba"] ["ab*a"] ["g"] -> ["aba", "aa", "abbbbbbbba", "abbbbbbbbbbbbba"]
{M,N}	matches the preceding character or group a minimum of M to a naximum of N times	["aba abbba abbbbba abbbbbbbbbbba"] ["ab{3,5}a"] ["g"] -> ["abbba","abbbbba"]
{,N}	matches the preceding character or group a maximum of N times	["aba abbba abbbbba abbbbbbbbbbba"] ["ab{,5}a"] ["g"] -> ["aba", "abbba", "abbbbba"]
{M,}	matches the preceding character or group a minimum of M times	["aba abbba abbbbba abbbbbbbbbbba"] ["ab{3,}a"] ["g"] -> ["abbba", "abbbbba", "abbbbbbbbbbba"]
{N}	matches the preceding character or group exactly N times	["aba abbba abbbbba abbbbbbbbbbba"] ["ab{3}a"] ["g"] -> ["abbba"]
[...]	syntax for any characters or group within the rectangular parenthesis	["Hello Hallo Hmllo Hkllo"] ["H[ea]llo"] ["g"] -> ["Hello","Hallo"]. This can also used like this: ["Hello Hallo Hmllo Hkllo"] ["H[a-k]llo"] ["g] -> ["Hello","Hallo", "Hkllo"]. which acts as every letter in the alphabet from a to k
|	seperating possible character or groups	["gray grey griy gary"] ["(gray|grey|griy)"] ["g"] -> ["gray", "grey", "griy"]
\w	syntax for all Alphanumericals (a-z A-Z 0-9 and _)	["This is a_text90§!"] ["\w"] ["g"] -> ["T","h","i","s","i","s","a","_","t","e","x","t","9","0"]
\W	syntax for all non-Alphanumericals not (a-z A-Z 0-9 and _)	["This is a_text90§!"] ["\W"] ["g"] -> ["§","!"]
