question & exclaimation marks

2020-08-24T00:38:51-04:00

What do you mean by filtering? If you mean to see if the string has any of the two then you got two options: string index or regexp.

string first

Code:

% set text "something ! in here"something ! in here% string first "!" $text10

notice that this returns the position of the needle in the haystack, so you need to do something like:

Code:

if {[string first "!" $text] > -1 || [string first "?" $text] > -1} {# do something}

regexp:

Code:

% regexp -- {\!|\?} $text1

notice that this one returns 0/1 (false or true) if any of the two is in there.

If you meant to replace/remove them from the string then you need string map like this:

Code:

% string map {"!" ""} $textsomething  in here% set text "something ? in here"something ? in here% string map {"?" ""} $textsomething  in here

Edit: Fixed a typo.

question & exclaimation marks

2020-08-22T23:07:06-04:00

Hi there

Am just trying to filter question marks or exclaimation marks in a string...just wondering if something like this is the right way about it:

Code:

if {[string match {*\?*} $var] || [string match {*\!*} $var]} {         do some stuff here etc}

Thanks in advance for any help!
