 Then copy & paste into FileMaker Advanced's Edit Custom Function window.

Description:

Isolates the first "word" of names written in camelCase. Useful for calculating names of layouts, fields, table occurrences, etc. Returns nothing if name has no capital letters or has spaces.

v 1.1: now uses recursive custom function to find first capital position (FM's built-in Position function is not case-sensitive):

FirstCapitalPosition ( text ; textLength )

This is my Custom Function and I want to edit it

Discuss:

try "camelCase". Doesn't work.

Thanks Fabrice. Obviously didn't test it thoroughly enough. I created a recursive function to take the place of FileMaker's Position function and edited the function to use it.

Hello,

Hello, here is a test without recursion

Let ([

txt = "camelCase" ;
M = Filter ( txt ; Upper ( Txt ))
];
GetValue ( Substitute ( txt ; left ( M ; 1 ) ; ¶ ) ; 1 )
)

give camel

in other words: to test the position of a capital letter, you'd better use a case sensitive function ;)

Filter ( text ; Upper ( text ) )

could fail if text contains numbers or other chars ( not alfabeth ).

Try this one too:

Let(
a = Left ( Filter ( text ; "ABCDEFGHIJKLMNOPQRSTUVWXYZ" ) ; 1 ) ;
If ( not IsEmpty ( a ) ; GetValue ( Substitute ( text ; a ; ¶ ) ; 1 )
))
