PRINT breaks up long strings that contain lots of spaces

[cbruce]

Strange behavior with PRINT command:

PRINT outputs additional newlines when simply printing long strings that contain lots of spaces to the console.

Just execute these two PRINTs and copy the output from the console and paste it into an editor that can handle long strings. You will see that the X-string wraps (had returns inserted) and the Z-string does not.

Code: Select all

print "[X                    X X          X  X  X   XX       X X          X      X    XX   X X   X X      X        XX  X      X  X  X     X X  XX   XX   X    X   X   XX     X       XXXX X  XX   X    X       X    X  XX  X XX X     X        XXX X   X   XX        XXXX    XXXXX  XX X    XX X   X X X      X  X  X   XXXX      X     X      XX X XXX  X      XX XXX    X        X   X]"
print "[Z____________________Z_Z__________Z__Z__Z___ZZ_______Z_Z__________Z______Z____ZZ___Z_Z___Z_Z______Z________ZZ__Z______Z__Z__Z_____Z_Z__ZZ___ZZ___Z____Z___Z___ZZ_____Z_______ZZZZ_Z__ZZ___Z____Z_______Z____Z__ZZ__Z_ZZ_Z_____Z________ZZZ_Z___Z___ZZ________ZZZZ____ZZZZZ__ZZ_Z____ZZ_Z___Z_Z_Z______Z__Z__Z___ZZZZ______Z_____Z______ZZ_Z_ZZZ__Z______ZZ_ZZZ____Z________Z___Z]"

Tested with FreeBASIC 1.09 and 1.08.

Although the line breaks can be different, depending on the string, they always show up at the same points for any given string.

Any ideas as to why PRINT doesn't always output to the console as expected?

Thanks,

No problem with Windows 10 and notepad.exe.

No problem here also W10 and another editor.

@cbruce Windows or Linux ?

With word wrap in notepad the first line of X's and Z's remains exact, the second line is one space off, the third two spaces off . . .
Similar with wordpad wrap to ruler, (but not exactly the same)
But using the crt puts and printf has the same effect in each also.

Same offsets with print directly to a file.
Win 10.

No problem with Windows 10 and notepad.exe.

I used notepad with word wrap turned off.

[dodicat]

With no word wrap everything matches here.

Word wrap (notepad) wraps differently with spaces and visible characters.
After all, words are generally separated by a space.
I tested on C also, same results as fb.

I am running Windows 10.

Here's what my output is like:

Code: Select all

[X                    X X          X  X  X   XX       X X          X      X    XX   X X   X X      X        XX  X      X  X  X     X X  XX   XX   X    X   X   XX     X       XXXX X  XX   X    X       X    X  XX  X XX X     X        XXX X   X   XX        XXXX    XXXXX  XX X 
   XX X   X X X      X  X  X   XXXX      X     X      XX X XXX  X      XX XXX    X        X   X]                                         
[Z____________________Z_Z__________Z__Z__Z___ZZ_______Z_Z__________Z______Z____ZZ___Z_Z___Z_Z______Z________ZZ__Z______Z__Z__Z_____Z_Z__ZZ___ZZ___Z____Z___Z___ZZ_____Z_______ZZZZ_Z__ZZ___Z____Z_______Z____Z__ZZ__Z_ZZ_Z_____Z________ZZZ_Z___Z___ZZ________ZZZZ____ZZZZZ__ZZ_Z____ZZ_Z___Z_Z_Z______Z__Z__Z___ZZZZ______Z_____Z______ZZ_Z_ZZZ__Z______ZZ_ZZZ____Z________Z___Z]                                         

For me, the line of X's gets broken into two lines.

Some more examples showing where the line breaks happen at different places for different strings:

Do you have width settings for the console?

Code: Select all

Sub changeconsolesize(cols As Long,lines As Long)
    Shell "MODE CON: COLS="+Str(cols)+ "LINES="+Str(lines)

changeconsolesize(400,20)

MODE CON: is cool @dodicat! Thanks!

For later searchers... after you've copied the data from the resized console... don't forget to reset the console size before exiting your program. Mine is normally 150w x 64h, so I just gave it this after I was done:

Code: Select all

changeconsolesize(150,64)

Here's a full example:

End Sub
Sub ChangeConsoleSize(iCols As Long, iRows As Long)
  Shell "MODE CON: COLS="+Str(iCols)+ "LINES="+Str(iRows)
