Subject [jira] [Commented] (ODFTOOLKIT-308) GSoC: ODF Command Line Tools
Date Thu, 15 Mar 2012 02:10:41 GMT


charitha Madusanka commented on ODFTOOLKIT-308:

In command-line paser we can identify a command output may input to another command . So implement
own piping machanisum for combaine commands (search, replace, merge) make help to minimue
uncompress/compress attempts.

> GNU/Linux, and UNIX before then has shown the great power of a text processing via simple
command line tools, combined with operating facilities for piping and redirection. This filter-baed
text processing is what makes shell programming so powerful.  But it only works well for text
documents.  But what about more complex, WYSIWYG documents, spreadsheets, word processors,
with more complex formats, often not text based at all?  The tool set becomes far weaker.
> The Apache ODF Toolkit is a Java API that gives a high level view of a document, and
enables programmatic manipulation of a document.  We have functions for doing things like
search & replace.  There is a lot you can do using the ODF Toolkit.  But it still requires
Java programming, and that limits its reach to professional programmers.
> What if we could write, using the ODF Toolkit, a set of command line utilities that made
it easy to do both simple and complex text manipulation tasks form a command line, things
> 1) Concatenate documents
> 2) Replace slide 3 in presentation A with slide 3 from presentation B
> 3) Apply the styles of document A to all documents in the current directory
> 4) Find all occurances of "sausages" in the given document and add a hyperlink to
> and so on.
> Clearly analogs of cat, grep, diff and sed are obvious ones. Maybe something awk-like
that works with spreadsheets?  No need to be slavish to the original tools, but create something
of similar power, but which operate on ODF documents.  For example, an alternative solution
might be to write a new shell processor that has native commands for ODF document manipulation.
