Hey Dav, what about this? - Routine to fetch file list
« on: January 25, 2021, 03:48:07 pm »
Just make sure you don't have any files named $my_tmp.tmp or $my_tmp2.tmp before you try it.

It makes a dir/files list like...

..
[Dir 1]
[Dir 2]
File1.foo
File2.foo
File3.foo

etc.

I have to augment the code for my date and time additions to the files, but without that info, this is all you need.

You probably already have this or a similar solution. I just posted it, since we are working on the same process.

Oh, if you are not familiar with the >> use in the second SHELL, it indicates APPEND to file instead of just WRITE to file.

Code: QB64: [Select]
  1. SHELL _HIDE "dir /b /A:D>$my_tmp.tmp"
  2. ff1% = FREEFILE
  3. OPEN "$my_tmp.tmp" FOR BINARY AS #ff1%
  4. ff2% = FREEFILE
  5. OPEN "$my_tmp2.tmp" FOR OUTPUT AS #ff2%
  6. PRINT #ff2%, ".."
  7. DO UNTIL EOF(ff1%)
  8.     LINE INPUT #ff1%, a$
  9.     a$ = "[" + a$ + "]"
  10.     PRINT #ff2%, a$
  11. CLOSE #ff1%, #ff2%
  12.  
  13. SHELL _HIDE "dir /b /A:-D *.*>>$my_tmp2.tmp"
  14.  
  15.  
  16. ' If you want to remove the $my_tmp.tmp and $my_tmp2.tmp files from the list, include this this...
  17. ' Otherwise use: SHELL _DONTWAIT "notepad $my_tmp2.tmp" here and end the routine.
  18.  
  19. ' Parse out      $my_tmp.tmp and $my_tmp2.tmp files from the list.
  20. ff1% = FREEFILE
  21. OPEN "$my_tmp.tmp" FOR OUTPUT AS #ff1%: CLOSE #ff1%
  22. ff1% = FREEFILE
  23. OPEN "$my_tmp2.tmp" FOR BINARY AS #ff1%
  24. a$ = SPACE$(LOF(ff1%))
  25. GET #ff1%, , a$
  26. CLOSE #ff1%
  27.  
  28. DO UNTIL INSTR(a$, "$my_tmp.tmp") = 0
  29.     a$ = MID$(a$, 1, INSTR(a$, "$my_tmp.tmp") - 1) + MID$(a$, INSTR(a$, "$my_tmp.tmp") + 13)
  30. DO UNTIL INSTR(a$, "$my_tmp2.tmp") = 0
  31.     a$ = MID$(a$, 1, INSTR(a$, "$my_tmp2.tmp") - 1) + MID$(a$, INSTR(a$, "$my_tmp2.tmp") + 14)
  32.  
  33. ff1% = FREEFILE
  34. OPEN "$my_tmp.tmp" FOR BINARY AS #ff1%
  35. PUT #ff1%, , a$
  36. CLOSE #ff1%
  37. REM If you want to KILL the unneeded second temporary file, use: ''IF _FILEEXISTS("$my_tmp2.tmp") THEN KILL "$my_tmp2.tmp"
  38.  
  39. SHELL _DONTWAIT "notepad $my_tmp.tmp"

Yep, That's about the way I'm doing it here.  But yours is working correctly, and mine was showing a duplicate entry for some reason. 

I completely forgot about >>! Thanks for reminding me. 

Edit:  Hey, @Pete, the way you're calling dir fixed my problem.  I was doing it wrong.  Thanks.  I'll update my code with the fix.

Glad it helped.

I'll post what I'm going to try as soon as I expand it to pick up the mix of directories and files with date and time creation. Also keep in mind, DOS did provide a variety of sorting switches:

N|-N - By name (alphabetical or reverse alphabetical).
E|-E - By extension ( alphabetical or reverse alphabetical).
D|-D - By date and time (chronologically or reverse).
S|-S - By size (increasing or decreasing).
C|-C - Sorts by DoubleSpace compression ratio lowest to highest or highest to lowest. (Version 6.0 only)
G|-G - Group directories (before, or after) other files.

Man...I've forgotten so much of dos commandline usage.  Gotta brush up on it again.  Thanks!

Here's how I do this type of thing -- I call one command, and have it sort things out for me into two arrays; one for directories and one for files.

Code: QB64: [Select]
  1.     FUNCTION load_dir& (s AS STRING)
  2.     FUNCTION has_next_entry& ()
  3.     SUB close_dir ()
  4.     SUB get_next_entry (s AS STRING, flags AS LONG, file_size AS LONG)
  5.  
  6. REDIM Dir(0) AS STRING, File(0) AS STRING
  7.  
  8.  
  9. GetFileList _CWD$, Dir(), File()
  10.  
  11. PRINT "SUBDIRECTORIES OF:"; _CWD$
  12. FOR i = 1 TO UBOUND(dir)
  13.     PRINT Dir(i),
  14. PRINT "FILES OF:"; _CWD$
  15. FOR i = 1 TO UBOUND(file)
  16.     PRINT File(i),
  17.  
  18. SUB GetFileList (SearchDirectory AS STRING, DirList() AS STRING, FileList() AS STRING)
  19.     CONST IS_DIR = 1
  20.     CONST IS_FILE = 2
  21.     DIM flags AS LONG, file_size AS LONG
  22.  
  23.     REDIM _PRESERVE DirList(100), FileList(100)
  24.     DirCount = 0: FileCount = 0
  25.  
  26.     IF load_dir(SearchDirectory + CHR$(0)) THEN
  27.         DO
  28.             length = has_next_entry
  29.             IF length > -1 THEN
  30.                 nam$ = SPACE$(length)
  31.                 get_next_entry nam$, flags, file_size
  32.                 IF _DIREXISTS(nam$) THEN
  33.                     DirCount = DirCount + 1
  34.                     IF DirCount > UBOUND(DirList) THEN REDIM _PRESERVE DirList(UBOUND(DirList) + 100)
  35.                     DirList(DirCount) = nam$
  36.                 ELSEIF _FILEEXISTS(nam$) THEN
  37.                     FileCount = FileCount + 1
  38.                     IF FileCount > UBOUND(filelist) THEN REDIM _PRESERVE FileList(UBOUND(filelist) + 100)
  39.                     FileList(FileCount) = nam$
  40.                 END IF
  41.             END IF
  42.         LOOP UNTIL length = -1
  43.         close_dir
  44.     END IF
  45.     REDIM _PRESERVE DirList(DirCount)
  46.     REDIM _PRESERVE FileList(FileCount)
  47.  
  48.  

Just copy direntry.h and put it in your folder with your BAS file and you're good to go.  Once compiled, it doesn't need to be shared (just like you don't have to share the BAS file itself), if all you want to do is distribute the executable.

Works on Windows, Mac, and Linux systems.

That does work very well, Steve.  I can get the filesize too fairly easy, STR$(file_size).

Works with the same direntry.h as above, so be certain to have that header file in the same folder as the BAS file which includes this.  Usage should be simple enough to sort out -- it's basically just a single line to call the routine, after the DECLARE LIBRARY is added.  In this case, it's a simple litte:

PRINT SelectFile$("*.bas;*.bi;*.bm;*.txt", 50, 50)

Nice one!  I'm saving it.  I think I'll add arrows to it, tab to switch panes.

Thanks for sharing!

And here's how I do it, but I'm shy, so I only do it over at my forum...

Last post.

Hey Dav and Steve,

If you could both check out the link above, you will see Bob commented on Dav's two latest programs, posted a very old keyboard routine of his own) and it looks like with some QB64 encouragement, he might expand that puzzle project of his to include all jpgs, like Dav's. He just isn't up on the new stuff, which limited him from doing it with QBasic in the first place. I can't help him with any of that, because I don't use the graphics statements. Anyway, it would be great to see TheBOB actively programming again. Maybe I'm not reading this right, but I think if he got acquainted and comfortable with some of new tools, he might just get the urge to write some more apps.

@Steve - I'll have a look at it. I've got a couple of alternate ways, Windows API, the code you posted, which I've seen somewhere around here, before, and the good ol' SHELL method posted at QBF.

Cool!  I would love to see TheBob active in QB64.  And I'm sure would be making some real pro stuff too!

Thanks for the link,@Pete.
