Priority: medium
Bug ID: 82580
CC: libreoffice@lists.freedesktop.org
Assignee: libreoffice-b...@lists.freedesktop.org
Summary: get rid of prewin.h / postwin.h wrapper headers
Severity: normal
Classification: Unclassified
OS: Windows (All)
Reporter: mst...@redhat.com
Hardware: Other
Status: NEW
Version: Inherited From OOo
Component: Libreoffice
Product: LibreOffice
includes of Win32 headers in LO are wrapped with
#include <prewin.h>
and
#include <postwin.h>
this is because old LO code, especially in "tools" and "vcl",
defines types that have the same names as Win32 types,
so the headers do a bunch of stupid macro hackery
to rename the Win32 types so they don't collide with LO types.
it would be obviously much simpler if the LO types
simply had names that don't collide with Win32 types.
"git grep" or ctags or opengrok.libreoffice.org
should find the definitions of types in LO that are re-defined
in the wrapper headers.
there are several ways to clean up collisions:
1) if there is no equivalent in LO of the redefined type,
it can just be removed from the wrapper header
2) in some cases it can be avoided to have the Win32 type
and the LO type visible in the same LO source file
by not including both the defining LO and Win32 headers
3) if the Win32 type is not a macro, then putting the LO
type into a namespace and namespace-qualifying the uses
should avoid the collisions
4) if the Win32 type is a macro, then adding a namespace-like
prefix to the LO type is probably required
