1. Request for help; A dir cmd (C-001655)

Hi,

I'm in urgent need for a directory command (Must be in Euphoria v3 / Win32Lib) that can list the following information;

- File/folder name - Owner - Accessed date

I'd like to have the output in an csv type file like this; name;owner;accessed

As it is quite urgent, I don't have the time to sit down and figure this out for my self, so I'd appreciate if any of you gentlemen/women could help me out here?

Thank you.

Kenneth / ZNorQ.

To get the file names from a directory ...

   // Check for command-line parameter; otherwise, print usage. 
   if(argc != 2)

I've already wrapped most of the code Derek posted into Euphoria for win_dir.

Hi Greg,

I've had a look through your code, and I see that it is only the "Modified date" that is returned (or am I mistaking?). I found out that with minor modifications I could get the "Created" and "Accessed" date too, but it would be nice to have this implemended in your orignal archive.

My solution is probably rather crude; that's because of my very basic knowledge of lowlevel memory handling, so I didn't want to mess too much around in your code.

What I did was to add a global integer (ZNQ_DATE_OUTPUT) that I'm using in the "format_entry()" function, where;

• 1 - Return Created date.
• 2 - Return Accessed date.
• 3 - Return Modified date.

I made sure that the global integer can't be lower than 1, nor higher than 3.

This is the changed code;

function format_entry( sequence wfd ) 
-- formats a proper dir() entry 
 
    sequence entry 
    object filetime, systemtime, localtime 
    -- 
    entry = repeat(0,9) 
    entry[D_NAME] = wfd[9] 
    entry[D_SIZE] = (wfd[5] * #10000) + wfd[6] 
    entry[D_ATTRIBUTES] = format_attrib( wfd[1] ) 
 
    filetime = FILETIME( wfd[ZNQ_DATE_OUTPUT+1] )     --<< Changes by ZNorQ. 
    localtime = allocate( FILETIME_SIZE ) 
 
    if c_func( xFileTimeToLocalFileTime, {filetime, localtime} ) then 
 
        filetime = localtime 
        systemtime = allocate( SYSTEMTIME_SIZE ) 
 
        if c_func( xFileTimeToSystemTime, {filetime, systemtime} ) then 
     
            systemtime = SYSTEMTIME( systemtime ) 
            entry[D_YEAR] = systemtime[1] - 1900 
            entry[D_MONTH] = systemtime[2] 
            entry[D_DAY] = systemtime[4] 
            entry[D_HOUR] = systemtime[5] 
            entry[D_MINUTE] = systemtime[6] 
            entry[D_SECOND] = systemtime[7] 
 
        end if 
 
    end if 
 
    return entry 
end function 
 
-------------------------------------------------------------------------------------- 
 
global function win_dir( sequence path ) 
-- returns directory information, given the name 
-- of a file or directory. Format returned is: 
-- { 
--  {"name1", attributes, size, year, month, day, hour, minute, second}, 
--  {"name2", ...                                                     }, 
-- } 
 
    sequence attrib 
    integer exit_code 
 
    -- 
    if   (ZNQ_DATE_OUTPUT < 1)    --<< Change by ZNorQ; Makes sure the integer isn't outside the legal range (1-3) 
    or   (ZNQ_DATE_OUTPUT > 3)    --<< ... 
    then  ZNQ_DATE_OUTPUT = 3     --<< Defaults to "Modified" date. 
    end   if                      --<< ... 
    -- 
 
    if path[$] != '\\' then 
        attrib = get_file_attrib( path ) 
        if find( 'd', attrib ) then 
            path &= '\\' 
        end if 
    end if 
     
    files = {} 
 
    exit_code = internal( path, gather_id, 0 ) 
    if exit_code then 
        return exit_code 
    end if 
 
    return files 
end function 

Can you confirm that this is a ok enough way to do this?

Ok, if there isn't anything I've missed, I'll just use it as is. I could ofcourse do as you proposed to do yourself - create a new function that accepts parameters; Should be alot better. I really hate abusing global vars!

Thanks!
