Status...: Is it still true?
|
|
|
|
***
|
|
|
|
Assign to: Ryszard, Przemek
|
|
Detail...: Debugger with basic interface written in C - it's enough to

|
|
|
***
|
|
|

|
|
Tasks for v.1 release:
|
|
----------------------
|
|
|
|
Assign to: <nobody>
|
|
Detail...: Rewrite filesys.c to use native platform specific file I/O
|
|
with unlimited number of file handles, while maintaining
|
|
compatibility with the CA-Cl*pper legacy handle numbering
|
|
system. This either involves adding a linked list for the
|
|
translation table, or we should state that only handles 0-4
|
|
are number compatible.
|
|
Status...: Open.
|
|
|
|
***

|
|
|
|
***
|
|
|
|
Assign to: <nobody>
|
|
Detail...: Add support for virtual file handles and registering some
|
|
meta handles so it will be possible to make:
|
|
h := fopen( "gzip:/tmp/myarchive.gz", FO_WRITE )
|
|
fwrite( h, cData )
|
|
fclose( h )
|
|
or:
|
|
h := fopen( "tcp:some.host:port", FO_WRITE )
|
|
...
|
|
or:
|
|
h := fopen( "|lpr -PLaserJet", FO_WRITE )
|
|
...
|
|
or:

h := fopen( "gunzip /tmp/myarchive.gz|", FO_READ )
|

|
etc.
|
|
Status...: Open.
|
|
|
|
***
|
|
|
|
Assign to: Przemek
|
|
Detail...: Define multi platform platform API for GTs which can mix
|
|
graphics objects with standard text output. Now it's
|
|
possible in GTXWC, GTWVT and GTALLEG. This I will discuss
|
|
yet also with xHarbour developers.
|
|
Status...: Open.
|
|
|
|
***
|
|
|
|
Assign to: <nobody>
|
|
Detail...: Add GTNET driver which will allow to run Harbour application
|
|
remotely. GTNET will be used on server side and on client
|
|
side any native GT driver.
|
|
Status...: Open.
|
|
|
|
***
|
|
|
|
Assign to: <nobody>

***
|
|
|
|
Assign to: <nobody>
|
|
Detail...: Add NETRDD - meta RDD which will allow transport layer
|
|
between client application and server application with any
|
|
other chosen RDD driver. Idea similar to GTNET but for RDD
|
|
drivers - it's sth like ADS does.
|
|
Status...: Open.
|
|
|
|
***
|
|
|
|
Assign to: Przemek
|
|
Detail...: Extended HB_IT_POINTER. In practice we can give them the
|
|
same functionality as for objects and use them for fast
|
|
creation objects at C level. We can also add HB_VALTYPE()
|
|
function which will return the extended type name, f.e.
|
|
"WINDOW", "FONT", "SOCKET" or anything what 3-rd party
|
|
programmers may want to use. It will greatly simplify
|
|
writing some libraries.
|
|
Status...: Open.
