[shuaijinchao]

代码

string.match([[/mnt/tmp/myfile.txt]], "(.-)([^\/]-%.?([^%.\/]*))$")
-- "/mnt/tmp/" "myfile.txt"    "txt"

string.match([[/mnt/tmp/myfile.txt.1]], "(.-)([^\/]-%.?([^%.\/]*))$")
-- "/mnt/tmp/" "myfile.txt.1"  "1"

string.match([[c:temptestmyfile.txt]], "(.-)([^\/]-%.?([^%.\/]*))$")
-- "c:\temp\test\"  "myfile.txt"    "txt"

string.match([[/test.i/directory.here/filename]], "(.-)([^\/]-%.?([^%.\/]*))$")
-- "/test.i/directory.here/"   "filename"  "filename"
