cfi.coffee to cfi.js

[Anthon]

I updated to 0.8.36 from the repository on an Ubuntu 11.04 box.

The EPUB book viewer is not running because cfi.js cannot be found.
After searching and finding cfi.coffee I installed coffeescript which did not improve anything, no install errors, and the same viewer message.

running "coffee -c cfi.coffee" by hand showed an error (either coffee is not called by "python setup.py install" or error output is gobbled), namely that nodejs is not found.
I changed the first line of /usr/bin/coffee from "#!/usr/bin/env nodejs" to "#!/usr/bin/env node"
and got errors that seem to have to do with coffee not being the right version.
Then on the coffeescript page somewhere it says:

If installing on Ubuntu or Debian, be careful not to use the existing out-of-date package.

and points to http://opinionatedprogrammer.com/201...ian-or-ubuntu/

Is there any list of prequisites and minimal versions of external software? Could setup.py install not check on the versions (assuming cfi.js is generated at install time, I am not sure).

There is no need for coffee or nodejs. If you are running from repository use python setup.py develop not python setup.py install. If you want to use install, use the source tarball of the release, not the repository version.

[Anthon]

Installing the package from ppa:gias-kay-lee/coffeescript does not work on 11.4.
The npm route (option 2 on opiniatedprogrammer.com) gets a working coffee.
Howerever setup.py would not call it.

I had to:
pushd src/calibre/ebooks/oeb/display
coffee -c cfi.coffee
cp cfi.js cp cfi.js ../../../../../resources/display/
popd
sudo python setup.py install

After that I could read books once more.

[Anthon]

python setup.py develop comes back with:

You need to ensure you have all of Qt installed, including QScriptEngine

I'd sure like to know what installs QScriptEngine in Ubuntu, as I can't seem to find it anywhere. I have all these installed (plus various others):

pyqt4-dev-tools
python-qt4
python-qt4-dev

For the time being I've simply reversed the recent changes serve_coffee.py so that I can continue to build calibre.

On gentoo it's qt-script, I have no idea about Ubuntu

Probably: libqt4-script

Sadly, that doesn't seem to help -- I've had that installed all along. I see the class being defined in this sip file:

python-qt4-dev: /usr/share/sip/PyQt4/QtScript/qscriptengine.sip

Aha! I need to change the source like this (in src/calibre/utils/serve_coffee.py):

-from PyQt4.Qt import QCoreApplication, QScriptEngine, QScriptValue
+from PyQt4.Qt import QCoreApplication
+from PyQt4.QtScript import QScriptEngine, QScriptValue

... then it works.

Talking it through works wonders (almost every time )

[kovidgoyal]

I've changed it in trunk. Though you might want to update your PyQt4 as that implies a rather old release.
