Adding a '$' to wordchars to select the entire variable name on double click no longer works.
in fact I can bugger up the wordchar variable in both share and ,config and it makes no difference as to what is selected on double click.
# wordchars=&@%$_abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789
wordchars=ABCDEFGHIJKLMNOPQRSTUVWXYZ
Operating system and Geany version please.
Adding "$" isn't taken into account because it is listed as a whitespace character in filetypes.common; and the latter overrides wordchars settings. I fixed this in Git so it's the wordchars setting that takes precedence -- which seems more natural.
Why listing only uppercase letters didn't work is similar, but not exactly the same: lowercase letters defaults as wordchars, and the wordchars setting actually only adds more characters, not replaces. This may not be expected nor correct, but at least it's not a common use case not to have the whole set of ASCII letters in wordchars, so it may -- or may not -- get fixed separately.
