Here is what I want to do but doesn't work:
mystring = "hello world"toUpper = ['a', 'e', 'i', 'o', 'u', 'y']array = list(mystring)for c in array: if c in toUpper: c = c.upper()print(array)
"e"
and "o"
are not uppercase in my array.
What is the idiomatic and most effecient way to check if a single character in Elisp is lowercase, uppercase, alphanumeric, digit, whitespace, or any other similar character category? For example Python has string methods like isdigit()
, but converting a character (which is just a number) to a string in Elisp to check if it belongs to a certain case or category seems like a wrong approach:
(string-match-p "[[:lower:]]" (char-to-string ?a))
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.
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 want to make the text that a user is typing into a textbox become uppercase. I know two ways to do this, which are:
Textbox1.Text = UCase(Textbox1.Text)orTextbox1.Text = Textbox1.Text.ToUpper
HOWEVER: both have the same problem (when embedded in a Textbox1_TextChanged
event handler), which is that the cursor keeps being moved back to the start, so if you slowly type in, say abcdef, it comes out as FEDCBA. Is there a way to move the cursor back to the end of the string after each time it works to make the text uppercase?
