| icyjug | could someone help with postscript? i have an array that i want to sort "naturally", i.e. like the command "ls -v" | 07:02.19 |
| camelopard | icyjug: Ghostscript has a bubble sort procedure in gs_init.ps. | 07:53.02 |
| | icyjug: % <array> <lt-proc> .sort <array> | 07:53.27 |
| icyjug | camelopard the problem with that is, if say there is a file named A9 and another A20, A20 gets listed before A9.. | 07:54.41 |
| | the "natural" sort, as in ls -v, doesnt do that | 07:55.23 |
| kens | You can write your own less than procedure | 07:55.24 |
| icyjug | kens complicated or easy? :S | 07:56.02 |
| kens | Depends what you want to do. I imagine most people would think it complicated | 07:56.19 |
| | But I have not had time yet to read the logs | 07:56.35 |
| icyjug | yeah i guess the sorting algorithm behind ls -v should be pretty complicated | 07:56.57 |
| | kens is it possible to mix bash and postscript? | 07:57.31 |
| | i have another bash script that sorts the filenames naturally in an array | 07:58.10 |
| kens | mix in what sense ? You can do processing in each interpreter and have it pass its results to the otheer via files for example. There is no interpreter that will handle both PostScript and bash scripting | 07:58.26 |
| camelopard | icyjug: Ghostscript can read and write files; the files can be named pipes. | 08:02.07 |
| icyjug | please have a look http://pastebin.com/ziB1f8sS http://pastebin.com/3iP8NXFc | 08:03.19 |
| | camelopard i just dont know how to declare files in postscript | 08:07.48 |
| | let alone process them | 08:08.00 |
| kens | the file operator takes a filename, an access flag and returns a file object | 08:08.14 |
| | You can then use readstring and readline to read from the file object | 08:08.32 |
| icyjug | readstring uses space as delimiter? | 08:09.10 |
| kens | But its probably easier to write the data as a PostScript file you can then 'run' from PostScript | 08:09.11 |
| | No, readstrsing has no delimiters | 08:09.20 |
| | It fills the string up to the decalred string size or until it runs out of data | 08:09.37 |
| | See the PostScript Language Reference Manual | 08:09.51 |
| | icyjug : I assume this is still down to creating bookmarks. I would suggest that you write a bash script which sorts the files into the order you want, then runs Ghostscritp with each file to determine the number of pages in each. Then write a *PostScript* program containing each pdfmark, using the number of pages at each point for the destination. | 08:13.44 |
| | Then have the same script invoke GS to process each PDF file in turn, feeding the files in the order you determined earlier. Finally send the PostScript program containing all the pdfmarks. | 08:14.25 |
| | I expect that will be easier for you than trying to program this in PostScript. | 08:14.39 |
| camelopard | icyjug: gs -dBATCH -dNODISPLAY -sLIST=<(ls) -c "LIST (r) file 10000 string readstring pop ==" | 08:20.38 |
| Robin_Watts | tkamppeter: Do you have a tool for converting cups rasters to some more standard image format? | 17:10.55 |
| camelopard | Robin_Watts: The tool was attached to one of the cups bugs. I used it. | 17:23.52 |
| Robin_Watts | camelopard: yeah, doesn't work for me :( | 17:24.03 |
| | If you mean readcups.c | 17:24.14 |
| chrisl | There is a viewer, if that would help | 17:24.26 |
| Robin_Watts | chrisl: ooh, that'd be ideal. | 17:24.36 |
| chrisl | http://www.msweet.org/projects.php?Z7 | 17:24.42 |
| Robin_Watts | I've just hacked a simple cups -> pbm converter. | 17:29.09 |
| chrisl | TBH, I thought bmpcmp already handled cups rasters | 17:31.02 |
| Robin_Watts | bmpcmp does :) | 17:39.49 |
| _johndoe | well it's more crowded than i expected | 18:56.42 |
| | hello the children of earth | 18:56.52 |
| | it seems like it's as quiet as it's crowded | 19:00.25 |
| tkamppeter | Robin_Watts, you should be able to convert CUPS Raster with any rasterto... filter of cups-filters and there is also rasterview to dispay files on the screen. | 21:10.56 |
