The method of extracting files without paths in VIM configuration encountered a headache during the configuration of previewing php files with VIM: I don't know how to extract files without paths, this is because php file preview uses a combination of URLs and file names without paths. For example, exec "! Google-chrome http: // 127.0.0.1/% ". In this case, enter" 127.0.0.1 // var/www/index. php ", an error will occur; then I searched on the Internet and finally found the solution, that is, using" %: t ", % is the file name with a path, followed by": t "indicates the file name without a path. in this way," 127.0.0.1/index. in this way, php can be previewed at any time during editing, which is much easier.
