Ascii-anims

Hi!

As I'm new to this group, here's some questions:

I've seen lots of sites with javascript- ascii anims.

I'm looking for ascii anims that can run in a unix-shell i.e. that use
escape codes - is that what we're talking about here?

Is it possible to convert java-asc-anims into shell-scripts (using printf)
?

You would have to remove extra \ from the JavascriptASCIIanimations but
otherwise I can't see that there would be a huge problem in converting
them. You would copy and paste the frames, remove one \ for every two
you find and remove all \r\n"+ and beginning ".

So the frames for this simple bird animation

"              \r\n"+
"  \<\")   \r\n"+
"   ( \>\\ \r\n"+
"    \" \\\\   \r\n"+
"       \\  ejm\r",

"              \r\n"+
"  \>\")   \r\n"+
"   ( \>\\ \r\n"+
"    \" \\\\   \r\n"+
"       \\  ejm\r"

would become:

               
   <")   
    ( >\ 
     " \\  
        \  ejm

            
   >")   
    ( >\ 
     " \\   
        \  ejm

I know very little about ascii animations that use escape codes but here
is what I found:

First you have to have an understanding of escape codes.  These are the
essential part of animations.  Without them, your animations won't work.
To create the actual "escape" character varies with different systems. 
The
ones I know are:

UNIX (vi editor)  : ctrl-v , then press the "esc" key (in insert mode)

VAX (eve editor)  : ctrl-v , then press the "esc" key

MSDOS editor      : ctrl-p , then press the "esc" key

after you have the initial character, there are several codes you can
enter to
manipulate the text and cursor.  Here is a list of the codes that I
know. 
These are to directly follow the "escape" character.  Also note that in
an
animation every code must have a preceding "escape" character.

(this list was compiled by someone else...not me...but here it is)

 Note that the case of the characters after the [ is important.  That
is, 
 [4a won't move the cursor, and [1;20R won't set any scroll regions)
 (from the vt220 reference book)

 Random Cursor Access on VT220 terminals.

[xA       move up x lines, same col.
[xB       move down x lines, same col.
[xC       move right x columns, same line.
[xD       move left x columns, same line.
E         locates at first spot next line.
[x;yH     locates at row,col (x,y).
[xJ       erases cursor pos to end of screen. x<>0,1,2
[x;0J     erases cursor pos to end of screen.
[x;1J     erases beg. of screen to and including cursor pos.
[x;2J     erases entire screen.
[xK       erases cursor pos to end of line. x<> 0,1,2
[x;0K     erases cursor pos to end of line.
[x;1K     erases beg. of line to and including cursor pos.
[x;2K     erases entire current line.
[xX       erases cursor pos and next x chars.
[t;br     sets lines from t to b as a scroll region.
[r        turns off scroll region.

 Character Attributes on VT220 terminals.

[0m    All attributes off
[1m    Intensity  only on
[4m    Underscore only on
[5m    Blinking   only on
[7m    Reverse    only on
[22m   Intensity  only off
[24m   Underscore only off
[25m   Blinking   only off
[27m   Reverse    only off

 To turn on several things at once, separate them by semicolons. eg:

 [22;7m 

 turns intensity off and reverse video on at the same time, but will not 
 affect other attributes.

 Single Height letters
#5string       prints string in single width.
#6string       prints string in double width.
#3topstring    prints top half of double-height string*
#4botstring    prints bot half of double-height string*
                             *Top and bottom strings must be identical.

***************************************

now back to me.....here some I'd like to add.....

  ** COLORS (my personal favorite) ***

[3#m    (where "#" is a number from 0 - 7) This changes the TEXT color
[4#m    (where "#" is a number from 0 - 7) This changes the BACKGROUND
colors

Colors:
Foreground                      Background
30 black                         40 black
31 red                           41 red
32 green                         42 green
33 yellow                        43 yellow
34 blue                          44 blue
35 magenta                       45 magenta
36 cyan                          46 cyan
37 white                         47 white

----------------------------------------------

Finally, after making the animation you must know how to view it.  
(replace "fiename.vt" with the animation name)

UNIX:           cat filename.vt 

VAX:            type filename.vt

DOS:            type filename.vt
        NOTE: In DOS it is required that ansi.sys is loaded with the
command:
                DEVICE = C:\DOS\ANSI.SYS
              in your CONFIG.SYS file.

...........................END

I hope that helps.

It just occurred to me that if you have more questions, try going to
DejaNews Power Search and search "R L Samuell" in
"alt.ascii-art.animation"

[][ hi... here is an alternative... which may save you some effort...

          if you use 'echo' in a unix shell script the escape char '\'
          will need to be 'escaped' thus '\\' and also some other
          shell-command-translation chars such as ` and " and $
      ... and remove the \r\n+ also

fanx for supplying the pics llizard ... makes it short and sweet

Oooops!

damn ... this don't work!

the variable in the 'for' loop should be FRAME not FRAMES

... i wrote this at work during lunch and re-wrote it, without looking,
from memory ...but didn't check it here :(

fortunately no-one tried it ... else they'd bleat about it

[ps] printf will work also if its on your machine ... but its not
     included in all unix distributions

[][ guess i'll have to go back to double-checking everything again
