Help with the trimleft/trimright function

 

I've taken my favourite script and tried to learn from it. It's probably is a bit complicated for a beginner but I really wanted to add a function to trim any leading and trailing whitespace characters and also add an option for Title case and Sentence case. I read the manual and all I can see is:

 ToLower + ToUpper

Is there another way to achieve Title case and Sentence case?

Any code that I've modified has --------------#### 3dwannab code ###-------------- beside it.

The area that needs attention is:

--------------#### 3dwannab code ###--------------

( if trailing_leading = false then

for i in selection do i.name = trimleft trailing_leading

--------------#### 3dwannab code ###--------------

 

I'm completely suck at the minute and I wanted to chat with someone on here to help me figure out what I need to do. I've managed to get the presets working as they should. It's just the function that needs a look at.

Thanks

I know this is an old thread

I know this is an old thread but you're right about dotnet:

/* FN to change text with arguments. Valid arguements are :-
(fn_changeCaseString "ToUpper") "string here"
(fn_changeCaseString "ToTitleCase") "string here"
(fn_changeCaseString "ToLower") "string here"
*/
fn fn_changeCaseString caseType =
(
	execute("(DotNetClass \"System.Globalization.CultureInfo\").CurrentCulture.TextInfo." + caseType)
)
 
-- FNs with arguements & Results:
(fn_changeCaseString "ToUpper") "test_text is HeRe. Respects ABV. words --> BRB UFC"
-- "TEST_TEXT IS HERE. RESPECTS ABV. WORDS --> BRB UFC"
 
(fn_changeCaseString "ToTitleCase") "test_text is HeRe. Respects ABV. words --> BRB UFC"
-- "Test_Text Is Here. Respects ABV. Words --> BRB UFC"
 
(fn_changeCaseString "ToLower") "test_text is HeRe. Respects ABV. words --> BRB UFC"
-- "test_text is here. respects abv. words --> brb ufc"

*CORRECT FILENAME*

fileP = "C:\temp\tempFolder\newFolder\tempFile.xxx"

(
	str = substituteString str "\n" "\\n"
	str = substituteString str "\t" "\\t"
)
correctString fileP
--> "C:\temp\tempFolder\newFolder\tempFile.xxx"

...

In the next few posts I will show some string functions.
Maybe some of them can be useful. Anyway ...
BTW are you trying to recreate Total Commander "Rename Multipe Files" window? :)

I only use the quick search

I only use the quick search did not elaborate on researching your script.

in your case:

(
if trailing_leading = false then
for i in selection do i.name = trimleft trailing_leading
)

I see in your script, the variable of 'trailing_leading' is a boolean, not a string

trimleft/trimright need a string (ie:name of object or any string)

for example to using them
a snippet from mxs help:

trimleft " \nMAXScript" --space and new line trimmed
 
--"MAXScript" -- it's result
 
 
trimright "$Teapot0911" "1234567890" --remove trailing numbers
 
--"$Teapot" -- it's result

or see example from barigazy
