I am new in regular expression. I want to remove a uppercase letter if it has lowercase before and after it. If the input is "I wilYl go theXre"
then the output should be "I will go there"
. How can I get it?
I have to rename a complete folder tree recursively so that no uppercase letter appears anywhere (it's C++ source code, but that shouldn't matter).
Bonus points for ignoring CVS and Subversion version control files/folders. The preferred way would be a shell script, since a shell should be available on any Linux box.
There were some valid arguments about details of the file renaming.
I think files with the same lowercase names should be overwritten; it's the user's problem. When checked out on a case-ignoring file system, it would overwrite the first one with the latter, too.
I would consider A-Z characters and transform them to a-z, everything else is just calling for problems (at least with source code).
The script would be needed to run a build on a Linux system, so I think changes to CVS or Subversion version control files should be omitted. After all, it's just a scratch checkout. Maybe an "export" is more appropriate.
What is an easy way in Golang to check if all characters in a string are upper case or lower case?
Also, how to handle a case where the string has punctuation?
See these examples:
package mainimport ( "fmt" "unicode")func main() { s := "UPPERCASE" fmt.Println(s.IsUpper()) // Should print true s = "lowercase" fmt.Println(s.IsUpper()) // Should print false s = "lowercase" fmt.Println(s.IsLower()) // Should print true s = "I'M YELLING AT YOU!" fmt.Println(s.IsUpper()) // Should print true}
Note: s.IsUpper() and s.IsLower() doesn't really exist, but would be nice to find an equivalent.
How can I convert all values in an array to lowercase in PHP?
Something like array_change_key_case
?
