Hi list,
please have a look at the patch I have attached.
I am trying to build a patch that reads from a txt file then outputs the text into Gem. I have done this. But I have a few questions that would help me take it further.
At the moment I am getting a lot of errors, its probably something simple but I have not found what it is yet?
One of the things I would like to do is get a piece of ascii art into Gem via a txt file, how do I get Gem to leave the spaces in? at present it just ignores more than one space.
I have the text moving up the screen, how would i get it to read each line of the txt file in order one at a time and display them without killing the previous line (think titles at start of starwars, ish).
Any other comments and advice greatly appreciated.
thanks
dominic

As I removed the connection between [textfile] and [text3d] I didn't get any errors - your patch seems to work properly. To ensure showing all words of a line add "list" to the begin of every line in your text file.

AFAIK [text3d] displays elements of a list and I don't know a way to generate an element of list with a blank. You'd want to use an escape character to code blanks in lists - AFAIK pd doesn't support such a thing (does it?).
I have the text moving up the screen, how would i get it to read each line of the txt file in order one at a time and display them without killing the previous line (think titles at start of starwars, ish).
What about one [text3d] for every line, moving up? It'll be a little bit sofisticated to synchronize all the [text3d] with one [textfile] - maybe you could try one [textfile] for every [text3d]?

all the text objects of the current gem cvs support multiple lines now - so you can load them in one object ... but you have to compile the gem version from cvs your self of course ...

if you want words, just use separate list atoms: a 3-atom list "1 2 3" will result in a text "1 2 3" (with blanks!) if you really want symbols with blanks, use [makefilename] and or [list2symbol], but there should be no need for it here.

yes, i'd also suggest using something like multiple [text3d]s. in the current CVS of Gem, the text-objects support multilined text (but you are on your own to generate a linebreak within a list!). it really depends on the text you want to do, whether this fits or not (e.g. if you have 1000 lines of text but you only want to display 5 lines at a time, you might be better off using 5 [text3d] objects instead of going through the hazzle with linebreaks)

Thanks for the advice everyone.
Yes the error was obvious, sorry.
The blanks is causing a problem as in some ascii art there can be just one character placed at any point on a line. But I need to keep the formatting of the line.
I'll have a play around with multiple text3d's
Cheers

sorry i didn't fully understand your problem. hopefully i now do: you need to preserve multiple blanks in a row. actually this is a problem with the parser of [textfile]/[msgfile], which automatically strips duplicate whitespaces.
however, multiple whitespaces are per se not a problem when it somes to [text3d]: using a tricky combination of whitespace symbols (made with [makefilename]) and concatenating them with [l2s] can produce any number of blanks within a symbol.
another possibility is, that the CVS-version of the text-objects can also be fed by ascii-code instead of symbols, compatible with moocow's pd-string library.
see attached file for examples for both ideas.
most probably it would be the simplest way, to just write an ascii-art reading object that outputs the ascii-encoded image. (using symbols for strings is sub-optimal)

Maybe it's a silly newbie question, but: I couldn't generate a list with multiple blanks in it. I tried following versions:
- [list 1 2 3( which results in 1 2 3 (as I'd expect)
- your example: [list "1 2 3"( which results in "1 2 3", cause " is not
a string quota
- [list 1 / 2 3( results in 1 / 2 3
- [list 1 \ 2 3( can't be input (pd: "\: dropped")
I even tried some weird things like:
- [list 1 2 3(
- [list '1 2 3'(
- [list 1 /0x20 2 3(
- [list 1 #0x20 2 3(
- [list 1 &0x20 2 3(
Blanks you suggested are just atom separators, so it's a special case of blanks in a string. Dominic wrote about ascii art with multiple blanks. How to encode a text file with multiple blanks which will be correctly read by [textfile]?

Hallo!
How to encode a text file with multiple blanks which will be correctly read by [textfile]?
also can't imagine how to do it with textfile ... anyway, there is a nother problem with textfile: if you have "," in a text you won't see the rest in text3d, because it is handled as a new message ... because of this I read the textfiles in python (py/pyext), where it should be also possible to generate symbols with more blanks ... (not tested)

actually it is fairly simple (piotr's attempts to escape characters made me think...) using "\ " instead of just " " is fairly trivial in your favourite editor (as long as it is not Pd...)
attached is an example how to load ascii-art into Gem.
anyway, there is a nother problem with textfile: if you have "," in a text you won't see the rest in text3d, because it is handled as a new message ...
like the spaces, it is just a matter of escaping: use "comma,comma" instead of "comma,comma" in your textfile (tested!)
