Hacking OpenOffice 140

prostoalex writes "Peter Sefton appreciates OpenOffice Writer's open and documented XML format and hence tries to customize and configure OO Writer to his own liking. In the article on XML.com he plays with OpenOffice XML, introduces an XSTL style sheet to a Writer document, creates a keyboard shortcut for applying his own style, and creates a macro."

    That's a lot you can do with xsltproc and unzip - but xsltproc is way to neat to call it a hack.
    Most day-to-day manipulations of Open-Office-Documents can easiely be done with perl:

      I've had similar issues. It's the i18n module that is most annoying to me, in that it is listed as a dependency (and so gets downloaded and installed) but isn't really required in a lot of cases. Yes the i18n support is a great thing... but could the packagers at the distros make it a little more optional?

Optional dependencies are usually not listed, and even if they are, you can use the Arch Build System to make your own package from the Arch stock PKGBUILD.

        I installed the openoffice package and couldn't figure out why it wouldn't run until I realized I hadn't installed the i18n-en files.

But I can install a subset of the suite, just the WP, and start it up, without failing for missing dependencies? Can I just install each component of the suite separately, and use each one independently? Would I be losing any "suite-wide" features? Maybe there's a way to startup just the WP, even if the whole suite is installed.

I'd select "File:Open", and wait a minute or so for a dialog to appear. That doesn't seem to have much to do with an installed spreadsheet. Though it did seem to be a problem with loading libraries on demand from disk, slowing interactivity of the GUI, rather than preloading the basic libraries at app startup.
