It might help if I explain what I want to do first. I would like to select a file from a folder, and then use walk_dir() to select and process all files in the same directory, but in a particular order based on the timestamp of the file. So I will select the oldest and then need the program to select progressively "newer" files which will be processed in turn.
Here is some example code, written using Euphoria v4 ...
include std/filesys.e include std/sort.e include std/io.e function process_file(sequence path_name, sequence item) -- this function accepts two sequences as arguments -- it displays all C/C++ source files and their sizes if find('d', item[D_ATTRIBUTES]) then return 0 -- Ignore directories end if sequence t t = fileext(item[D_NAME]) if not find(t, {"c","h","cpp","hpp","cp"}) then return 0 -- ignore non-C/C++ files end if writefln(1, "[][][]: [] []/[z:2]/[z:2] [z:2]:[z:2]:[z:2].[z:3]", {path_name, {SLASH}, item[D_NAME], item[D_SIZE], item[D_YEAR], item[D_MONTH], item[D_DAY], item[D_HOUR], item[D_DAY], item[D_SECOND], item[D_MILLISECOND]}) return 0 -- keep going end function function my_dir(sequence path) object d d = dir(path) if atom(d) then return d end if -- Sort in ascending time stamp. return sort_columns(d, {D_YEAR, D_MONTH, D_DAY, D_HOUR, D_MINUTE, D_SECOND, D_MILLISECOND}) end function integer exit_code sequence cmds cmds = command_line() exit_code = walk_dir(cmds[3], routine_id("process_file"), 1, routine_id("my_dir"))
