StringRegExp problem

[avechuche]

First of all, sorry for my bad English

I need 2 things, first I need to check a username supports only lowercase letters, uppercase and point. [.a-zA-Z]

But I need that username, not start with it a period "."

^[^.][.a-zA-Z]+$

I have that expression, but not fully functional.

 

2) I need to check a number, but I need that number can not start with 0. I have this expression, but does not work very well ^[^0]d+$

 

Thx!

1) ^[^.][A-Za-z]+$

2) ^[^0]d+$

1) ^[^.][A-Za-z]+$

2) ^[^0]d+$

 

No

1) I replace the first expression by "^[a-zA-Z]+(.?[a-zA-Z]+)?$" and it works, but I think it can be smaller.

2) This expression is the same as mine, but it does not work.

Forgot you wanted to match usernames with dots but without starting with a dot. Correction: ^[^.][.A-Za-z]+$

consolewrite("#1 '0321'=>"&StringRegExp("0321",'^[^0]\d+$')&@LF)
consolewrite("#2 '321'=>"&StringRegExp("321",'^[^0]\d+$')&@LF)
consolewrite("#3 '.usErname'=>"&StringRegExp(".usErname",'^[^\.][\.A-Za-z]+$')&@LF)
consolewrite("#4 'usErname'=>"&StringRegExp("usErname",'^[^\.][\.A-Za-z]+$')&@LF)
consolewrite("#5 'usErn.ame'=>"&StringRegExp("usErn.ame",'^[^\.][\.A-Za-z]+$')&@LF)

If in front of "=>" is a "1" = it matched, if is a "0" = failed to match.

If in front of "=>" is a "1" = it matched, if is a "0" = failed to match.

 

Try this 

ConsoleWrite("#2 ' 0321'=>" & StringRegExp(" 0321", '^[^0]\d+$') & @LF)

and

ConsoleWrite("#5 'usErn.ame'=>" & StringRegExp("m", '^[^\.][\.A-Za-z]+$') & @LF)

PD: 

Within [], no need to use "" to escape characters.

 

Ex ==> [?] = [?]

Forgot that kind of scenarios

^[^.]?[.A-Za-z]+$

^[^0]?d+$

both will fail if a space is added,

EDIT: those doesn't work since "?" is lazy, my bad

for what you proposed this works

^[^.][.A-Za-z]+$

^[^0]d+$

 

if you don't care about spaces being on your string

^[^.][.A-Za-zs]+$

[^0]?[ds]+$ ;Still mess up, it willl need lookahead RE

The first was solved so

 

"^[a-zA-Z]+(.[a-zA-Z]+)?$"

 

ave.chuce ==> 1

avechuche ==> 1

.avechuche ==> 0

avechuche. ==> 0

[^0]?[ds]+$ It continues to resist.

ConsoleWrite("#2 '321'=>" & StringRegExp(" 0321", '^[\s][^0][\d\s]+) & @LF) = 0 OK
ConsoleWrite("#2 '321'=>" & StringRegExp("321", '^[\s][^0][\d\s]+) & @LF) = 0 BAD
ConsoleWrite("#2 '321'=>" & StringRegExp("321", '^[\s]?[^0][\d\s]+$') & @LF) = 1 OK
ConsoleWrite("#2 '321'=>" & StringRegExp(" 321", '^[\s]?[^0][\d\s]+$') & @LF) = 1 OK
ConsoleWrite("#2 '321'=>" & StringRegExp(" 0321", '^[\s]?[^0][\d\s]+) & @LF) = 1 DEM BAD

I guess I need some sleep, can't see what I'm doing wrong

I'm not sure why we are including spaces now... but you can add the "s" wherever you see fit.

The neat thing about regex is that there are many ways to skin the cat.

Here's a method that wasn't used:

ConsoleWrite(( _
    StringRegExp("01234", "^(?!0)\d+\z") _
    = True) & @CRLF) ; fails as it should
ConsoleWrite(( _
    StringRegExp("12340", "^(?!0)\d+\z") _
    = True) & @CRLF) ; succeeds as it should

ConsoleWrite(( _
    StringRegExp(".userName", "^(?i)(?!\.)[\.a-z]+\z") _
    = True) & @CRLF) ; fails as it should
ConsoleWrite(( _
    StringRegExp("u.serName", "^(?i)(?!\.)[\.a-z]+\z") _
    = True) & @CRLF) ; succeeds as it should

Great! You can add that you can not use a period at the end and I need to prevent two or more continuous point?

 

avechuche. ==> False.

ave..chuche ==> false

For the first, you can try wiht this : "^[a-zA-Z]+(.[a-zA-Z]+)*$"       or       ^([[:alpha:]]+)(.(?1))*$

It should match something like User.Na.me, UserName ....

For the second : "^[1-9]d*$"

From the help file under 'Datatypes' we have,
"A value 0 will be equal to Boolean False
Any other number value will be equal to Boolean True."

So in the example, if the first regex is true then the first regex does not equal zero.. Therefore, the first expression 'regex <> 0' is true.

If the second regex is false (meaning there are no two dots next to each other) then the second regex  equals zero.   Therefore, the second expression 'regex = 0' is true.

Now when the  first 'regex <> 0' is True And the second 'regex = 0' is true the outcome of the two expressions combined with And  is true
If either or both expressions are false then the combined outcome is false.

Local $aList[4] = ["u.serName", ".userName", "userName.", "u..serName"]

For $i = 0 To UBound($aList) - 1
    ConsoleWrite(((StringRegExp($aList[$i], "^(?i)(?!\.)[\.a-z]+(?<!\.)\z") <> 0) And _
                  (StringRegExp($aList[$i], "\.\.") = 0)) & @TAB & $aList[$i] & @CRLF)
Next

#cs Returns :-
True    u.serName
False    .userName
False    userName.
False    u..serName
#ce

One expression (jguinch's one) should suffice

Local $aList[6] = ["userName", "u.serName", "u.ser.Name", ".userName", "userName.", "u..serName"]

For $i = 0 To UBound($aList) - 1
    ConsoleWrite(StringRegExp($aList[$i], '(?i)^([a-z]+)(\.(?1))*$' ) & @TAB & $aList[$i] & @CRLF)
Next

@mikell : I think the "?" is not useful. Why did you add it ?

[mikell]

It is not. Its a remnant from an other try, sorry

[avechuche]

Thank you all, this is the final expression.

Local $aList[7] = ["userName", "u.serName", "u.ser.Name", ".userName", "userName.", "u..serName", "aaa.bbb"]

For $i = 0 To UBound($aList) - 1
    ConsoleWrite(StringRegExp($aList[$i], '(?i)^([a-z]+)(\.(?1))?$' ) & @TAB & $aList[$i] & @CRLF)
Next
