yal is yet another locater application. Click Select on its iconbar-icon to edit the searchfile, then drag a file or a directory onto the iconbar-icon, and it will report in a taskwindow all those lines in the file or in files within the directory that satisfy the criteria specified by the lines of the searchfile. Each criterion may be plain text or a pattern, and may be positive (must occur) or negative (must not occur). Criteria may be written in any order. Click Adjust on the iconbar-icon to edit the configuration file: which filetypes, which leafnames may be searched and whether the search is to recurse through subdirectories.
