Modify file name {fname} according to {mods}. {mods} is a string of characters like it is used for file names on the command line. See |filename-modifiers|. Example: :echo fnamemodify("main.c", ":p:h") results in: /home/mool/vim/vim/src If {mods} is empty then {fname} is returned. Note: Environment variables don't work in {fname}, use |expand()| first then. Can also be used as a |method|: GetName()->fnamemodify(':p:h')
