'unattended' export / file conversion?
Hello,
I find OmniGraffle very easy to use and certainly my preferred vector drawing editor. However for one of my acitvities I need to publish lots of small diagrams in a more standard (web-friendly) format (GIF/PNG, maybe PDF or SVG). It is a pain to have to 'make a change, select export, complete the export dialog, repeat". I'd love to set up an automator workflow or similar (even a launchd supervised shell script watching a directory full of graffle files) that would automatically generate a corresponding GIF/PNG/whatever every time it saw a change in the source graffle file. i.e. the workflow becomes: 'make a change, Save, wait a few seconds'. Alas, I can't find any such functionality in the current OmniGraffle - am I asking too much? Thanks, Ben |

Hi Ben, This isn't available built-in to OmniGraffle itself, but it is possible to do it via Graffle's AppleScript support. In fact, it made for a nice little scripting project last night. Just paste the following into Script Editor, and follow the instructions. [CODE] -- Here is an AppleScript that will watch a folder for changes to Graffle files and automatically convert them to another format. Before use you should: -- 1. Change the properties at the beginning to match the behavior you would like as far as where to watch and what type to export as. -- 2. Towards the bottom there is a "here is where you set the export settings" section where you can do the AppleScript equivalent of setting various controls on Graffle's export panel. You may want to change the export settings here. See Graffle's AppleScript dictionary for details on the setting names, and et cetera. -- 3. Finally, you may also need to change the application name from "OmniGraffle Professional" to just "OmniGraffle" in process_item if you have the standard version instead of pro. -- Then just run the script. It will keep running forever until you manually stop it. You could set it up as a startup item if desired. -- a file extension which Graffle supports for export property new_extension : "png" -- the folder to watch property watch_folder : "Macintosh HD:Users:toon:Desktop" -- the subfolder inside the watch folder where the exported documents should go property export_foldername : "Images" -- amount of time to wait in between checking for file changes property seconds_between_checks : 30 tell application "Finder" -- set up the watch folder and create the export folder inside tell application "Finder" set watch_folder to watch_folder as alias if not (exists folder export_foldername of watch_folder) then make new folder at watch_folder with properties {name:export_foldername} end if set the export_folder to (folder export_foldername of watch_folder) as alias end tell -- repeat forever repeat -- get all the graffle files in the watch folder set fileList to files of watch_folder whose kind is "OmniGraffle document" repeat with aFile in fileList -- figure out what the new exported name would be set new_name to my rename(aFile, new_extension) set the target_path to (((export_folder as string) & new_name) as string) -- if there isn't an export file or if the graffle file is newer, do the export if (not (exists document file new_name of export_folder)) or modification date of aFile > modification date of document file new_name of export_folder then my process_item(aFile as alias, new_name, export_folder) end if end repeat -- wait before we look again delay seconds_between_checks end repeat end tell -- this sub-routine just comes up with the new name on rename(this_item, new_extension) tell application "Finder" set the file_name to the name of this_item set file_extension to the name extension of this_item if the file_extension is "" then set the trimmed_name to the file_name else set the trimmed_name to text 1 thru -((length of file_extension) + 2) of the file_name end if set target_name to (the trimmed_name & "." & new_extension) as string end tell return the target_name end rename -- this sub-routine does the export on process_item(source_file, new_name, results_folder) set the source_item to the POSIX path of the source_file set the target_path to (((results_folder as string) & new_name) as string) with timeout of 900 seconds tell application "OmniGraffle Professional" -- save the current export settings so we can replace them later set oldAreaType to area type of current export settings set oldBorder to include border of current export settings -- here is where you set the export settings you want set area type of current export settings to all graphics set include border of current export settings to true -- open the file if it isn't already open set needToOpen to (count (documents whose path is source_item)) is 0 if needToOpen then open source_file end if -- do the export set docsWithPath to documents whose path is source_item set theDoc to first item of docsWithPath save theDoc in file target_path -- if the file wasn't already open, close it again if needToOpen then close theDoc end if -- put the original export settings back set area type of current export settings to oldAreaType set include border of current export settings to oldBorder end tell end timeout end process_item [/CODE] |
[edited to replace my "v0.1" semi-broken hackery of Greg's script]
Woohoo! Thanks Greg! This just about does the trick. I modified the script to a 'droplet', which remembers lists of files and folders to watch and exports the new versions alongside the graffle files (e.g. foo.graffle -> foo.graffle.png). I just drag the graffle files I want auto-exported to this script app, and start the script after I start OG. If OG isn't running when the script is launched, it will 'batch update' any watched files/folders and then exit. [AS rant: I've got years of experience in C, Perl, and other assorted languages, yet AppleScript is just so damned opaque to me.... I wanted to test if OG had any open, modified docs, but I could only get the expression "count (document's modified)" to work - my old English teacher would crucify me :-) I also found weirdness with AppleScript's handling of the quit statement (see comments in the code below), and it took me ages of fiddling to figure out the difference between the alias and 'object' (Finder?) file reference types... I can say for sure Greg that without your script to work from I would've given up in dismay] BTW, I played with calling the script via a Folder Action ('items added'), and via launchd (WatchPaths), and found that in both these cases the script will only be called for *new* files, not modifications to existing files. Presumably OG opens and overwrites the same file when saving, rt. creating a new one and unlinking the old, and thus neither launchd's WatchPaths nor the Folder Action pick up the change (as the file modification doesn't change the containing directory). Pity, as this would be a neat way of on-demand launching the script. Thanks very much for the script!

Exporting Individual (Selected) Objects
Hi,
I have also been working on an export script, but with a little different flavor. I use OG 4 to draw a bunch of buttons/icons in one canvas. Then, in the "Note" for each object I want to export I put the text "ExportTo[filename]" Anyway, this seems to work, and as it wasn't very obvious to me (an intermittent Applescripter at best) I post it here in case its useful: (ps. if anyone has a simple way to do regular expressions in Applescript on the note contents would be nice to simplify into filename = first group of match regex "exportTo[.*?]" on string this_note or something like that!

New version - handles package files
The previous version of the script did not handle package files. There were two problems:[LIST][*] a package is basically a folder (trailing ":" or "/"), so exported files were created as file.graffle/.png, and [*] OG 4.1.2 has a "bug" in that its 'documents whose path ...' strips the trailing "/", which confuses the find-the-document-we-just-opened logic. I just loooove Applescript.[/LIST]
