OK. Here is another task. Recursively walk directory, find all .jpg files which names are integers, sort the names by numbers and print the result.

Ruby (one line):
Code: [Select]
puts Dir.glob("**/*").select{|a| File.extname(a) == ".jpg" and File.basename(a, ".jpg").to_i.to_s == File.basename(a, ".jpg")}.map {|a| File.basename(a, ".jpg").to_i}.sort

If you want to know what part of the code is responsible for what part of the task, I can explain it to you. It only looks cryptic. If you know basics of Ruby it's clear as
Code: [Select]
for x = 1 to 10 : print x : next x
in BASIC.  ;)

Tomaaz do you have sample screen shot of output. I am probably going to repeat a question about "map" but it might be solved by picture.

Also I assume it doesn't have to be .jpg extension or start with number maybe any base name condition is good.
I'd prefer to build something that actually might have some use for me and this sort of stuff is not but a .bas file starting with certain base names might be very useful. I mean I hate to be accused of playing around ALL of the time with my BASIC's.


@ Mike
The B of B+ mostly stands for Build as in B += .... But standing for Eternal Beginner is OK too, someone should keep the eternal flame alive.

B+,

Actually my remark was there to cut down a little that bitter taste the whole incident left in my mouth. :)

History spins in circles, and we've seen all this before on the old BP.org. But IIRC then the instigator was that narcissistic graphomaniac that used to call himself menn, or mennonite, or bestof, or something similar. It's sad to see other people stepping into his place on this newer forum board.

Output is just a bunch of numbers and it depends on what is in the directory you're running the script in.

You mean the incident where John continued slagging off other BASIC interpreter authors and calling their hobbies and efforts "toys" and worthless pursuits as opposed to his "professional" BASIC interpreter which everyone should be using (either as a template for other languages or outright as the only tool in their box)? Where I decided I'd had enough of his bitching and sniping and called him out on it? And where he flounced out of the forum - as he has done before on previous boards - in righteous indignation?

That incident?

Because god forbid that anyone gets any enjoyment out of something they create for their own pleasure, yeah?

This is all I have to say regarding the topic, and as I have already said, I will abstain from any further fruitless discussions on it here or elsewhere.

Find yourself another target. I've seen enough of it on the old BP.org and am pretty much fed up with it since years.

Oh, I'm not trolling. Even you will be able to tell when I am.

You viciously and without provocation attacked me personally, and I'm not allowed to even defend myself? I'll add that the list of things I'm not allowed to do according to some guy on the internet who goes by the name of Mike, yeah?

Mike, I don't remember ZXDunny trolling anyone. He's never had problems with people using other BASICs, unlike some other members. He's never had problems with me posting code in Python, Ruby or Perl, unlike some other members. You want to see some good trolling? Sorry, you just missed one. It was here. Aurel was having laugh at OOP. It involved words like "pussy", "suck" etc., but Aurel must have gotten sober in the meantime and edited it.

Well I finally got a useful directory walk working from SmallBASIC.

Chris has a Keyword DIRWALK but it isn't easy for me to use but I bet Chris could extract 100 x's faster than I.

Here is code I came up with (not nearly so elegant as Ruby one liner) to extract and sort only .bas files:
Code: [Select]
'Dir Walk.bas for SmallBASIC 0.12.13 B+ 2018-09-24

CONST DEBUG = TRUE

FUNC sto(x)
  IF DEBUG THEN ? x   'debug: line record returned by DIRWALK, you should see how this monster is formatted!!!!
 
  'the extraction begins, remove brackets and split to fields
  SPLIT DISCLOSE(x, "{}"), ",", field
 
  'the name is in the 2nd field but is it a Folder name or File name?
  SPLIT field(1), ":", names
 
  'extract actual name value from names array
  name = MID(names(1), 2, LEN(names(1)) - 2)
  IF DEBUG THEN ? "Name: ";name  '<<< debug: got name right?
 
  'extract path from 6th field   
  path = DISCLOSE(RIGHTOF(field(5), ":"))
 
  'I think either "\" or "/" is being mistaken for escape code but works so... you know...
  IF MID(path, LEN(path)) = CHR(47) OR MID(path, LEN(path)) = CHR(92) THEN path = MID(path, 1, LEN(path) - 1)
  IF debug THEN ? "Path: ";path '<<<<<< debug: got path right?
 
  pathedName = path + CHR(92) + name
  IF DEBUG THEN ? "Pathed Name: ";pathedName
   
  'debug: view each return one at a time
  IF DEBUG THEN
    INPUT "OK, press enter to continue, any other + enter to quit ";wate
   
    'This doesn't always stop DIRWALK ???
    IF LEN(TRIM(wate)) THEN sto = FALSE : EXIT FUNC
    ?
  FI
 
  IF LCASE(RIGHT(pathedName, 4)) = ".bas" THEN container << pathedName
  IF x <> "" THEN sto = TRUE
END

DIRWALK "." USE sto(x)
SORT container

'check and file results
FOR i IN container DO ? i
tsave "BAS files.txt", container


Attached is a view of a debug session when everything was working to my satisfaction (good enough). You need to see the string DIRWALK returns until it's USE function returns FALSE.

Here is output file, BAS files.txt:

Too many I's in BASIC and the alternating slants or slashes :P

I like Tomaaz challenges, both interesting and productive for me even if they fail to be impressive.

Oh sorry Chris, I guess I didn't like pixelate? was that the cat thing? I mostly didn't like it because it didn't fit the screen, the lines were too long and printing over into next line ruining the image produced.

You know this challenge was originally directed at Script Basic, I confess now that I worked up my boring example (probably not a great example of SmallBASIC) and Peter his, could someone offer a good representative one of Script Basic code? Maybe AlyssonR or (old) Mike?

Heck! I wouldn't mind seeing new Mike's version either! :) maybe a GUI sample, I would think it actually useful and not waste of time.

And D, can SpecBas do this?

Well I knew John couldn't answer my question. This is probably his real reason for leaving, this challenge.

And the attached shows the Standard response when you ask a question he can't answer about Script Basic and he is the one who wants to be surrounded by professional programmers.

Just for fun - pure assembly, of course:
Code: [Select]
include \masm32\MasmBasic\MasmBasic.inc
  Init
  Let esi=ExpandEnv$("%WINDIR%\")+"*.*" ; usually C:\Windows
  PrintLine "Searching ", esi
  GfCallback cbGetFiles ; define a callback function
  GetFiles esi
  Print Str$("\n%i files found\n", eax) ; 2805 files found
  For_ ecx=0 To Min(19, Files$(?)) ; print a few
PrintLine Files$(ecx)
  Next
  Store "NumericalFiles.txt", Files$() ; write the complete list to disk
  Exit
cbGetFiles:
  test ecx, 1048575 ; file or folder counter
  If_ Zero? Then Print "*" ; console mode progress bar ;-)
  .if [ebx.WIN32_FIND_DATAW.dwFileAttributes]==FILE_ATTRIBUTE_DIRECTORY
clc
  .else
void Val(Utf8$(esi))
.if edx==-127
stc
.elseif edx<20
clc
.else
stc
.endif
  .endif
  ret
EndOfCode
Typical output:

To list all files, all you need in Ruby is:
Code: [Select]
puts Dir.glob("**/*")

Hey JJ,

Nice to see MasmBasic in action again. Are the files coming out sorted automatically?



Hi all,

Last night I rediscovered this crucial line for QB64 processing of pathedfile lists:
Code: [Select]
SHELL _HIDE "DIR " + spec$ + " /b /s /o:gen > " + TmpFile$
Which brings back fond memories of my days with DOS.

When you launch SmallBASIC you are actually looking at the output from the DIRWALK command.

(SmallBASIC runs main.bas which provides the user interface)
