I'm trying to script the Save Document command

What I've got will run to the first 'asecho ' command and not reach the second.

What I'd like to do is create a backup of any file being edited on my local host even if it is a remote document. I'm quite sure that the fault is in my script and not in BBEdit. I searched the archives here and found nothing related to this problem.

Anyone smarter about AppleScript (and almost everyone here would fit that statement) care to point out the error of my ways?

Thanks

David

-- text document doc

on documentDidSave(doc)

-- do shell script "~/asecho 1 running"

set fromFTP to doc is FTP

-- do shell script "~/asecho 2 post fromFTP"

if fromFTP then

-- set path to URL of doc

set _ftpinfo to FTPInfo of doc

set _path to path of _ftpinfo

set _host to host of _ftpinfo

do shell script "~/asecho 3 " & quoted form of _host

set u to URL of doc

do shell script "~/asecho 4 " & u

set p to POSIX path of _path

do shell script "~/UnixEnvironment/src/script/backuptext " & p

else

set f to file of doc

set p to POSIX path of f

do shell script "~/UnixEnvironment/src/script/backuptext " & p

end if

end documentDidSave

Hi David,

`try ... on error` blocks are very useful for debugging scripts.

Before porting it to a Document Script, test your logic in the Script Editor where you can use the `log` and `display alert/dialog` commands to debug.

Use `the quoted form of` for paths included in your `do shell script` commands, otherwise any space in the path will break your command.

This example snippet run from the Script Editor might help you.

tell application "BBEdit"
try
set vDocument to first text document
if vDocument's is FTP then
set vFTPInfo to (vDocument's FTP Info) as record
set vFile to vFTPInfo's file
set vHost to vFTPInfo's host
-- set vURL to vFTPInfo's URL -- WARNING: triggers an error even though the property exists and is visible in the results pane.
set vURL to vDocument's URL
log {vHost, vURL}
else
if vDocument's modified then
save vDocument
end if
set vFile to vDocument's file
end if
log vFile
set vPosixPath to POSIX path of (vFile as string)
log vPosixPath
do shell script "ls -al" & space & the quoted form of vPosixPath
on error aMessage
display alert aMessage
end try
end tell

Jean, your script works when run as an osascript, however I'm trying to run the script as a BBEdit OnDocumentSave

In that case I've fixed the syntax errors (as best I can, probably incorrectly) and it only runs to the first 'do shell script', nothing after that executes.

$HOME/asecho is just "echo $* >> $HOME/Desktop/trace" for logging purposes.

-- text document doc

on documentDidSave(vDocument)

do shell script "$HOME/asecho run"

if vDocument is FTP then

do shell script "$HOME/asecho is FTP file"

set vFTPInfo to FTPInfo of vDocument

set vFile to vFTPInfo's file

set vHost to vFTPInfo's host

-- set vURL to vFTPInfo's URL -- WARNING: triggers an error even though the property exists and is visible in the results pane.

set vURL to vDocument's URL

log {vHost, vURL}

do shell script "$HOME/asecho is FTP file" & vHost & " " & vURL

else

do shell script "echo is NOT FTP file"

if vDocument's modified then

save vDocument

end if

set vFile to vDocument's file

set vPosixPath to POSIX path of (vFile as string)

do shell script "$HOME/asecho is NOT FTP file" & the quoted form of vPosixPath

end if

log vFile

set vPosixPath to POSIX path of (vFile as string)

log vPosixPath

do shell script "$HOME/asecho run ls on " & the quoted form of vPosixPath

do shell script "ls -al" & space & the quoted form of vPosixPath

end documentDidSave

David,

A couple of reasons your script is not working:

• `if vDocument is FTP then`

As this is not in a `tell application "BBEdit` block, AppleScript interprets
the `is` as the equals operator `=` as in `if Document = FTP then`.
To interpret the `is FTP` as a BBEdit `Document` property AppleScript needs the
BBEdit terminology which is imported by the `tell application "BBEdit"`.

There is a second issue. `is FTP` is a property of `vDocument`.
This should be stated as `is FTP of vDocument` or in the shorter possessive
form `vDocument's is FTP` (note the `'s`).

• `FTPInfo`

This property of `Document` should be spelled `FTP info` in two words as
indicated in the BBEdit terminology.

Here is a snippet that seems to work on my setup:

use AppleScript version "2.7"
use scripting additions
--
on trace(aMessage)
set vDesktopFolder to POSIX path of (path to desktop folder as string)
set vTraceFile to vDesktopFolder & "trace.txt"
do shell script ("echo" & space & (the quoted form of aMessage) & ">>" & (the quoted form of vTraceFile))
end trace
--
on documentDidSave(vDocument)
try
tell application "BBEdit"
if class of vDocument is text document then

if vDocument's is FTP then

set vFTPInfo to FTP Info of vDocument

set vFile to vFTPInfo's file
set vHost to vFTPInfo's host

set vURL to vDocument's URL

my trace("is FTP file" & linefeed & vHost & linefeed & vURL)
else
my trace("is NOT FTP file")

set vFile to vDocument's file

end if

set vPosixPath to POSIX path of (vFile as string)

my trace(vPosixPath)
my trace("")
end if
end tell

on error aMessage
display alert aMessage
end try

end documentDidSave

HTH,

Jean Jourdain
