I skimmed through the 16 pages of the thread, and there might be an answer, but I have no notion of python and such. I have Windows 7 64bits, calibre 1.2 and Sigil 0.7.2.

FWIW Sigil is at 7.3 and works on W7 64

The message indicates a unicode decode problem.
Try with an English only filename as a test

I downloaded the 7.3 Sigil, and tried it with another English book (I think this morning's was English too), similar problem:

PS: What is FWIW an acronym for? I knew only FYI.

@kiwidude -

UPDATE - Ignore this whole question. I misunderstood Kovid, he's adding what I wanted to calibre's eject feature directly, so I don't need to call anything.

I don't know if you've been following this thread, Nook STRg doesn't eject completely?, but Kovid was kind enough to make a utility program for the next version that unmounts usb devices before ejecting them.

My intention is to make my SmartEject PI (configurably) call it.

Rather than reinvent the wheel, would you mind if I had SmartEject call Open With, since it already knows how to run programs on all the OSes? Something like:

ow_plugin = self.gui.iactions['Open With']
ow_plugin.launch_app("path_to_install\calibre-eject.exe","g h i","")

Except with configurable values, of course.

Initial testing seems like it works fine.

Except not really.

calibre-eject chokes on the empty parameter from the empty path_to_file.

And changing launch_app to work without path_to_file would require changes to all three OS paths, so I'll understand if you don't want to do that.

[JimmXinu]

Just in case you are interested, here's a modified version of launch_app(). I've only tested it with windows.

Spoiler:

    def launch_app(self, external_app_path, app_args, path_to_file=None):
        external_app_path = os.path.expandvars(external_app_path)
        if path_to_file != None:
            path_to_file = path_to_file.encode('utf-8')
        if DEBUG:
            print('Open: ', external_app_path, '(file): ', path_to_file, ' (args): ', app_args)

        if isosx:
            # For OSX we will not support optional command line arguments currently
            if external_app_path.lower().endswith(".app"):
                args = 'open -a '
            else:
                args = ''
            args += '"%s"' % external_app_path
            if path_to_file != None:
                args += ' "%s"' % path_to_file
            subprocess.Popen(args, shell=True)

        else:
            # For Windows/Linux merge any optional command line args with the app/file paths
            app_args_list = []
            if app_args:
                app_args_list = app_args.split(',')
            app_args_list.insert(0, external_app_path)
            if path_to_file != None:
                app_args_list.append(path_to_file)
            if iswindows:
                if path_to_file != None:
                    # Add to the recently opened files list to support windows jump lists etc.
                    from win32com.shell import shell, shellcon

                DETACHED_PROCESS = 0x00000008
                if external_app_path.lower().endswith('sigil.exe'):
                    clean_env = dict(os.environ)
                    del clean_env['PATH']
                    subprocess.Popen(app_args_list, creationflags=DETACHED_PROCESS, env=clean_env)
                else:

                    si = STARTUPINFO()
                    si.dwFlags |= _subprocess.STARTF_USESTDHANDLES
                    print("OW cmd_line:%s"%cmd_line)
                    CreateProcess(None, cmd_line, None, None, False, DETACHED_PROCESS, None, None, si)

[kiwidude]

No worries, ignore is default mode at moment unless a bug due to lack of time

[At_Libitum]

I did search the topic if it was asked but either I chose the wrong search or it's not yet asked.

I see on the menu that it is capable of detecting which items are applicable in a given presence of formats for a book.

I would like to suggest an enhancement if this is possible.

On the configuration dialog, allow us to mark an entry as the default if more than one program is configured to open a specific format, and then on left click on the plugin icon, launch that entry.

e.g. I have a book with an additional .djvu format. WinDjView on the pen drive, and left click would then open WinDjView...(no file associations on portables)

I realize that if multiple formats are present, it would be up to the user to select which is the preferred one, and that there can only be one, as in such cases a choice would need to be made which format is the preferred. That is if there is a combination of multiple formats. If there is only one candidate activated then just launch whatever is the enabled menu entry.

And since epub seems to work from the details panel even without file associations, I am trying to find a way to do same with the non-epub formats, or at least those the built-in viewer can't handle. Since the details panel requires associations for these I was hoping perhaps via Open With would be an option

[kiwidude]

@At_Libitum - its an interesting idea, and not something I can see any major flaws in that you haven't mentioned (other than lack of time at the moment to implement it). I confess to just using keyboard shortcuts to launch applications - you might consider that as a more flexible option as it gets around the multiple formats issue.

[PeterT]

Kiwi; you might be interested in bug 1256198 which seems to indicate a cause for the sporadic reports from calibre on startup of

ERROR: Problem starting the wireless device: The wireless device driver did not start. It said "Failed to connect to port 9090. Try a different value.

[sengian]

A plugin modification adding translation of the plugin (general pot and french done).
Not extensively tested, for review and test.

EDIT:
-19/07/2014 Port to Qt5 (davidfor modifications included)
-18/01/2015: v1.5.9 modifications included

I just went to use Openwith (Sigil) PI which has been solid thru 1.27.

I can still run Sigil. Tap 'O', Use the Windows context manager to "Open with Sigil"

@theducks - Open With Sigil working OK here

Win7-SP1, calibre 64bit 1.28, Sigil Windows build 0.7.4

Pity it doesn't tell us which file it can't find

First callback line # Confirm we have defined an application for that format in tweaks


The second line must be part of Calibre.

OK all Openwiths are failing
I have restarted Calibre.
The timestamp on Open With.json is 12/7/2013
Note the SPACE in the JSON file name
Almost all the JSON's associated with PI's have a space
