Previously, all of the README files have been renamed to README.md and now, the contents of these files were changed to use Markdown format. Other than format inconsistency, some README.md files lacked information about modules, or were out of date. By using LibreOffice / OpenOffice wiki and other documentation websites, these files were updated. Now every README.md file has a title, and some description. The top-level README.md file is changed to add links to the modules. The result of processing the Markdown format README.md files can be seen at: https://docs.libreoffice.org/ Change-Id: Ic3b0c3c064a2498d6a435253b041df010cd7797a Reviewed-on: https://gerrit.libreoffice.org/c/core/+/113424 Tested-by: Jenkins Reviewed-by: Michael Stahl <michael.stahl@allotropia.de> Reviewed-by: Adolfo Jayme Barrientos <fitojb@ubuntu.com>

# Import Filter for File Format of Lotus Word Pro (lwp)
|
|
|
|
## Description
|
|
|
|
The import is not direct, but via an intermediate format: StarOffice
|
|
XML, the predecessor of ODF (yes, the code is old). The entry point to
|
|
the filter is class LotusWordProImportFilter (refer to Source code
|
|
section), but that just hooks up the necessary machinery for processing
|
|
StarOffice XML produced by the filter. The real fun starts in function
|
|
`ReadWordproFile()` (`source/filter/lwpfilter.cxx`); this function
|
|
initializes the parser (class `Lwp9Reader`) and the SAX XML handler that
|
|
produces the output (class `XFSaxStream`). The Lwp9Reader class then does
|
|
the actual parsing.
|
|
|
|
If the module is built with debug level greater than 0, it is possible
|
|
to examine the intermediate XML: set environment variable
|
|
`DBG_LWPIMPORT_DIR=` to an existing directory and, on opening an lwp
|
|
document, a file named `lwpimport.xml` will be created in that directory.
