Excellent stuff.

Image in frame, how does that work for syntax ?

Sad, doesn't work.

I posted a howto here for building a simple gtkdialog frontend to a command line program from a template (I forgot to add radio buttons - oops)

http://www.murga-linux.com/puppy/viewtopic.php?t=45474

another thing I found useful was to use pfind to search for files containing gtkdialog (the list more than filled my screen)

any feedback is welcome

Hy.

After i hammered puppypdf for 4.3 release to work, i was thinking on redooing it in gtkdialog for three reasons. First is that newer puppy aps are using gtkdialog, looks better, and all Razz secondly becouse i use some ps2pdf features for optimization so i was thinking why not include them in the gui.
Thirs is that i prefer to have a one step aproach intead of the wizard style of puppypdf.

So as i never touched gtkdialog before i hacked together something which is pre-prealpha. just i cant get one thing going.

When i open a file in the first box, i would like to automatically fill the save box with originalfile.name.pdf

I cant figure out how to do that?

Code:


#! /bin/bash

TITLE="PPDF 0.1.2"
ORIGIFILE=""
PDFFILE=""
GUI="yes"

function ppdf_convert() {
  TMPFILE="/tmp/tmp.ps"
 
  if [ "$GUI" = "yes" ]; then
    `Xdialog --timeout 2 --msgbox "STARTING CONVERSION" 0 0`
  else
    echo "STARTING CONVERSION"
  fi
 
  ABIW_OUT=`abiword --to=ps --to-name=$TMPFILE $ORIGIFILE`

  PSPDFOUT=`ps2pdf -dPDFSETTINGS=/$OPTIMIZE $TMPFILE $PDFFILE`
 
  if [ "$GUI" = "yes" ]; then
    `Xdialog --timeout 2 --msgbox "FINISHED" 0 0`
  else
    echo "FINISHED"
  fi
}

export DIALOG='
<window title="'$TITLE'" icon-name="gtk-dnd">
  <vbox>

    <hbox>
      <pixmap icon_size="8">
   <input file stock="gtk-dnd"></input>
      </pixmap>
      <vbox>
   <text use-markup="true">
     <label>"<b>'$TITLE'</b>"</label>
   </text>
   <text>
     <label>Convert TXT, RTF, DOC, HTML ... etc, to PDF</label>
   </text>
      </vbox>
    </hbox>

    <hbox>
      <text>
   <label>Original file:</label>
      </text>
      <entry accept="filename">
   <variable>ORIGIFILE</variable>
   <input>echo $ORIGIFILE</input>
      </entry>
      <button>
   <input file icon="gtk-open"></input>
   <action type="fileselect">ORIGIFILE</action>
   <action>refresh:ORIGIFILE</action>
   <action>echo $PDFFILE</action>
      </button>
    </hbox>

    <hbox>
      <text>
   <label>PDF file:</label>
      </text>
      <entry accept="savefilename">
   <variable>PDFFILE</variable>
   <input>echo $PDFFILE</input>
      </entry>
      <button>
   <input file icon="gtk-open"></input>
   <action type="fileselect">PDFFILE</action>
   <action type="refresh">PDFFILE</action>
      </button>
    </hbox>

    <hbox>
      <text>
   <label>Optimize for:</label>
      </text>
      <combobox>
   <variable>OPTIMIZE</variable>
   <item>default</item>
   <item>screen</item>
   <item>ebook</item>
   <item>printer</item>
   <item>prepress</item>
      </combobox>
    </hbox>

    <hbox>
      <button>
   <label>Create PDF</label>
   <action type="exit">OK</action>
      </button>
      <button cancel>
      </button>
    </hbox>

  </vbox>
</window>'


I=$IFS; IFS=""
for STATEMENTS in  $(gtkdialog3 --program DIALOG); do
  eval $STATEMENTS
done
IFS=$I

if [ "$EXIT" = "OK" ]; then
  ppdf_convert
else
  echo "Canceled"
fi



Any ideas are welcome.

please consider that it may be rewritt4en to use eventdriven mode

nikin,

Not sure if this would work, but what about adding a function for the first box like this-

<action>FUNCTION-TO-CONVERT-ORIGINALFILENAME-TO-PDF</action>

Then in the second box put <default>$NEW-VARIABLE-CREATED-BY-FUNCTION(originalfile.name.pdf)</default>

Another possibility is just to convert it directly without the second box to "originalfile.name.pdf" -probably what most would do Very Happy

if it is from input such as gtkpdf /path/to/file.extension

put either '$1.pdf' or $1.pdf as default

but this would give you "file.extension.pdf"

there are several bash scripts available to remove extensions using for instance basename and sed

it would look like
DEFAULTFILENAME=......$1
then use $DEFAULTFILENAME in the default section

I don't have my puppypc right now but googling "remove extensions basename sed" give a bunch of examples

You probably could -

Code:

PDFVARNAME="`basename $ORIGINALNAME | cut -d. -f1`.pdf"

Maybe.. but i still would like to write a good program Razz

There is a slight misunderstanding on what i need help in.
Thanks for the tips for file name generation...but what i need is the way how to make gtkdialog use that name.

Quote:

<action>FUNCTION-TO-CONVERT-ORIGINALFILENAME-TO-PDF</action>

Then in the second box put <default>$NEW-VARIABLE-CREATED-BY-FUNCTION(originalfile.name.pdf)</default>


idid try this... with nno luck.
The value justwont get in the box.

Dear nikin,

Please have a look at the attachment. I added some default file name handling and made pdfprint suitable for use in Rox using a right click on html, doc, rtf and txt (Customize Menu in Rox after a right click on one of those files and create a symlink to pdfprint). It works. Thanks for producing it.

With kind regards,
vovchik

Dear vovchik

Nice addition to the code. Thank you.
I think after i get this "filename in gtkdialog" thing done, we can release it. I also consider to add more ps2pdf options to the program.

One thing:

you have written

Code:

cd /root/my-documents


and i would suggest

Code:

cd ~/my-documents


this makes the program multiuser compatible. Even if it is not yet used like that.

Thanks again.

Perhaps this is the problem - your code is using "entry accept"

Quote:
Code:
<entry accept="savefilename">
   <variable>PDFFILE</variable>
   <input>echo $PDFFILE</input>
      </entry>


try this-

Code:
 <entry activates-default="true">
        <default>$PDFFILE</default>
        <variable>PDFFILE</variable>
      </entry>

Dear nikin,

I think this is a nice and useful little app. I restructured the code a little, mostly for optics but also to relegate the processing to functions and to make a minimal main, since I am an old Pascal/Modula freak. Have you tried seaside's suggestion? I am about to.

With kind regards,
vovchik

Sorry I am kind of new in this.
Can you please explain what this changes?

Dear vovchik,

Slowly you can claim to be the author of the program Razz as the number of line writen by you exceed the original Smile
I am ok with the pascal aproach Razz maybe the processPDF could be merged into the connverter routine... but thats all.
I didnt try. i don't realy understand. what that would change, as this is the first time i touch gtkdialog Razz

one question:
why do you export ORIGIFILE and not PDFFILE ?

Bests Razz
