Q: Get list of layer names from PSD file.
-
Mar 11, 2015 6:33 AMby VikingOSX,This works for me on a four layer photoshop image. Note. the do shell script returns the layers in a list starting with the bottom layer.
set this_item to POSIX path of (choose file with prompt "Choose file to record path name")
set nLayersName to {}
set matchLayer to "Main Image"
set nLayersName to getNameOfLayers(this_item)
log nLayersName as text
if isMatchLayer(nLayersName, matchLayer) then
display dialog "Matched " & matchLayer
else
display dialog "Layer " & matchLayer & " not found."
end if
on getNameOfLayers(f)
set matchCmdStr to " | egrep -io '(\".+\")'"
set mdlsCmd to "mdls -name kMDItemLayerNames "
return do shell script (mdlsCmd & f's quoted form & matchCmdStr)
end getNameOfLayers
on isMatchLayer(psdLayers, matchItem)
set matched to false as boolean
repeat with layer in paragraphs of psdLayers
if matchItem is in layer then
set matched to true
end if
end repeat
return matched
end isMatchLayer

Updated AppleScript
set this_item to POSIX path of (choose file with prompt "Choose file to record path name")
set nLayersName to {}
set matchList to {}
set matchLayer to "Main Image"
set nLayersName to getNameOfLayers(this_item)
log nLayersName as text
set matchList to isMatchLayer(nLayersName, matchLayer)
if item 1 of matchList then
display dialog "Matched " & matchLayer & space & (item 2 of matchList) & " times."
else
display dialog "Layer " & matchLayer & " not found."
end if
on getNameOfLayers(f)
set matchCmdStr to " | egrep -io '(\".+\")'"
set mdlsCmd to "mdls -name kMDItemLayerNames "
return do shell script (mdlsCmd & f's quoted form & matchCmdStr)
end getNameOfLayers
on isMatchLayer(psdLayers, matchItem)
set matched to false as boolean
set matchCount to 0 as integer
repeat with layer in paragraphs of psdLayers
if matchItem is in layer then
set matchCount to matchCount + 1
set matched to true
end if
end repeat
return {matched, matchCount}
end isMatchLayer

Mar 11, 2015 10:54 AMby VikingOSX,I just realized that the following had to be updated to return *all* layer names – quoted, and unquoted. It looks for anything in quotes, or any alphanumeric string. Finally, it simply excludes the kMDItemLayerNames line from the result.
set matchCmdStr to " | egrep -io '(\".+\"|[[:alnum:]]+)' | egrep -v 'kMDItemLayerNames'"

Basically, it says ignore any lines that match the regular expression (the double \\ is to appease AppleScript), print the others, and the second awk removes the leading white space for nice left flush returns.
set matchStr to " | awk '!/kMDItemLayerNames|\\)/' | awk '{$1=$1}1' "

Mar 12, 2015 10:28 AMby VikingOSX,Glad to help. Using Affinity Designer and Photo here myself.
The following Terminal command will show the Photoshop files that have a Shadow layer in them.
mdfind -onlyin ~/Downloads -name 'kMDItemLayerNames == "*Shadow*"cdw && kMDItemContentType == "*photoshop*"cdw' "
Result: DV25NW07779MU3GO.PSD

Mar 13, 2015 4:57 AMby MattJayC,I'm still trying to apply this in my script.
The error I get
Result:
error "Finder got an error: Can’t continue getNameOfLayers." number -1708
I've added the handlers
This is the script.
tell application "Finder"
set HotDestination to (((path to pictures folder) as text) & "HotDestination")
set HotFolder2do to (((path to pictures folder) as text) & "HotFolder2do")
set HotFolderDone to (((path to pictures folder) as text) & "HotFolderDone")
repeat with tFile in (get document files of folder HotDestination whose name extension is in extension_list and (name does not start with "50" or name does not start with "MJC"))
set nLayersName to getNameOfLayers(tFile)
set matchList to isMatchLayer(nLayersName, matchLayer)
if item 1 of matchList then
move tFile to the folder HotFolderDone -- move to subFolder A
else
move tFile to the folder HotFolder2do
end if
end repeat
end tell

Mar 13, 2015 7:08 AMby MattJayC,Not sure thats the issue, I think it might be to do with the way the file is being located.
repeat with tFile in (get document files of folder HotDestination whose name extension is in extension_listand (name does not start with "50" or name does not start with "MJC"))
There can be more than one file in the folder, so it would need to check and move each one?

Mar 13, 2015 8:42 AMby MattJayC,Here is how I am using it. In full
There was a space on the original code.
property type_list : {"TIFF", "JPEG", "PNGf", "PICT"}
property extension_list : {"tif", "tiff", "jpg", "jpeg", "png", "pict", "psd"}
set nLayersName to {}
set matchList to {}
set matchLayer to "Shadows"
tell application "Finder"
set HotDestination to (((path to pictures folder) as text) & "HotDestination")
set HotFolder2do to (((path to pictures folder) as text) & "HotFolder2do")
set HotFolderDone to (((path to pictures folder) as text) & "HotFolderDone")
repeat with tFile in (get document files of folder HotDestination whose name extension is in extension_list and (name does not start with "50" or name does not start with "MJC"))
set nLayersName to getNameOfLayers(tFile)
set matchList to isMatchLayer(nLayersName, matchLayer)
if item 1 of matchList then
move tFile to the folder HotFolderDone -- move to subFolder A
else
move tFile to the folder HotFolder2do
end if
end repeat
end tell
on getNameOfLayers(f)
set matchCmdStr to " | awk '!/kMDItemLayerNames|\\)/ { sub(/[ ]+/, \"\"); print }' "
set mdlsCmd to "mdls -name kMDItemLayerNames "
return do shell script (mdlsCmd & f's quoted form & matchCmdStr)
end getNameOfLayers
on isMatchLayer(psdLayers, matchItem)
set matched to false as boolean
set matchCount to 0 as integer
repeat with layer in paragraphs of psdLayers
if matchItem is in layer then
set matchCount to matchCount + 1
set matched to true
end if
end repeat
return {matched, matchCount}
end isMatchLayer

Mar 13, 2015 10:15 AMby VikingOSX,Is your script now working correctly?
What happens if tFile is not found/set in that repeat clause logic? Passing an undefined tFIle into the getNameOfLayers function would wreak havoc. I would test for a valid tFile before passing it into the getNameOfLayers function.
