TITLE
AslToRT
VERSION
39.8
AUTHOR
Thore Böckelmann <tboeckel@uni-paderborn.de>
REQUIREMENTS
Any Amiga® (compatible) computer with at least OS3.0 and 68020+ cpu.
DESCRIPTION
AslToRT is a utility that is meant to replace RTPatch by Nico François, the
original author of the ReqTools package. RTPatch has several bugs when running
under OS3.x. It uses a very tricky mechanism to patch the desired libraries
only when they are opened. This causes a very annoying behavior with
asl.library. Under OS2.x this library kept its open counter equal to zero,
which is no longer the fact for OS3.x. As a result the library's name is
changed from "asl.library" to "asl.§ibrary", where the "§" stands for an
unprintable character. The effect is, that asl.library will be loaded again
and again, because it is no longer in memory with the correct name. This is
very bad in the way Amiga shared libraries are intended to work. So you have
no longer one copy of the library in memory, but several identical copies, of
which each eats up your machines memory.
AslToRT does all the things that RTPatch does, but in a (hopefully) much
better way. Additionally you can choose very exactly which libraries and which
functions should be patched to use the apropriate ReqTools function.
From version 39.2 on AslToRT can behave like a fictious program called
"RTToAsl", that means it can redirect all of reqtools' requesters to the
equivalent asl requesters. The desired work mode is selected by the new
PATCHMODE option.
USAGE
You can start AslToRT from either Workbench or Shell with the following
options:
ASLFILE/S,ASLFONT/S,ASLSCREEN/S,ASLALL/S,INTUIAUTOREQ/S,INTUIEASYREQ/S,
INTUIALL/S,REQFILE/S,REQFONT/S,REQLONG/S,REQSTRING/S,REQTEXT/S,REQCOLOR/S,
REQALL/S,ARPFILE/S,ARPALL/S,REQTOOLSFILE/S,REQTOOLSFONT/S,REQTOOLSSCREEN/S,
REQTOOLSALL/S,ALL/S,PATCHMODE,IGNOREHEIGHT/S,CENTERTEXT/S,OVERRIDE/S
ASLFILE/S: patch asl.library's file requesters
ASLFONT/S: patch asl.library's font requesters
ASLSCREEN/S: patch asl.library's screenmode requesters
ASLALL/S: patch all of asl.library's requesters
INTUIAUTOREQ/S: patch intuition.library/AutoRequest()
INTUIEASYREQ/S: patch intuition.library/EasyRequest()
INTUIALL/S: patch all of intuition.library's requesters
REQFILE/S: patch req.library's file requesters
REQFONT/S: patch req.library's font requesters
REQLONG/S: patch req.library/GetLong()
REQSTRING/S: patch req.library/GetString()
REQTEXT/S: patch req.library/TextRequest()
REQCOLOR/S: patch req.library/ColorRequest()
REQALL/S: patch all of req.library's requesters
ARPFILE/S: patch arp.library's file requesters
ARPALL/S: patch all of arp.library's requesters
REQTOOLSFILE/S: patch reqtools.library's file requesters
REQTOOLSFONT/S: patch reqtools.library's font requesters
REQTOOLSSCREEN/S: patch reqtools.library's screenmode requesters
REQTOOLSALL/S: patch all of reqtools.library's requesters
ALL/S: patch all requesters of every library (asl/arp/req/intuition/reqtools)
PATCHMODE: either ASL or REQTOOLS (default: REQTOOLS)
IGNOREHEIGHT/S: ignore the height of file/font/screenmode requesters and use
ReqTools' preferred window height
CENTERTEXT/S: center the body text of AutoRequest()/EasyRequest()ers
OVERRIDE/S: override fallback to asl.library for some unsupported features and
use ReqTools requesters nevertheless
You must specify at least one of these options, else AslToRT will exit
immediately without patching anything.
You can start and quit AslToRT at any time. Only requesters allocated after
running AslToRT will be redirected to ReqTools. To quit AslToRT simply start
it again.
INSTALLATION
Copy AslToRT where ever you want, but SYS:WBStartup is a very good place
KNOWN BUGS
reqtools.library is not able to emulate all details of asl.library. Especially
the very new functionality introduced with asl.library V44 (OS3.9) cannot be
done with reqtools.
Some requesters by intuition/AutoRequest() cannot be patched to
reqtools.library because they use some tricky mechanisms to place the text
within the window, which reqtools.library cannot do (i.e. the device info
requester of DiskSalv V2+).
Most of Workbench's and dos.library's message requesters can be redirected to
reqtools.library, but some cannot. These are the requesters that are build by
intuition/BuildSysRequest() and intuition/BuildEasyRequest() and are displayed
asynchronously. Although reqtools.library itself can do the same thing it is
not possible to emulate intuiton.library's way by reqtools.library (i.e.
Workbench's Version/Copyright requester).
Since version 39.2 you can redirect reqtools' requesters to asl, but the
asychronous requesters of reqtools cannot be emulated by asl, therefore these
requesters will not be redirected. But as it is very hard to find programs
using reqtools.library directly these days I assume this is not a very big
drawback.
For those who are interested, AslToRT patches the following functions (if
enabled via options):
asl.library:
AllocAslRequest()
FreeAslRequest()
AslRequest()
intuition.library:
AutoRequest()
EasyRequestArgs()
req.library:
FileRequester()
GetLong()
GetString()
NewGetString()
TextRequest()
ColorRequester()
ExtendedColorRequester()
arp.library:
FileRequest()
reqtools.library:
rtAllocRequest()
rtFreeRequest()
rtFreeFileList()
rtChangeReqAttr()
rtFileRequest()
rtFontRequest()
rtScreenModeRequest()
HISTORY
39.1 (03.01.2001):
- initial Aminet release
39.2 (10.05.2001):
- result for intuition/AutoRequest() was swapped. Fixed.
- added possibility to use AslToRT for redirection of reqtools requesters to
asl instead of vice versa.
39.3 (11.06.2001):
- sometimes files didn't pass the filter functions because the current
directory wasn't set correctly. Thus WBPattern didn't allow to select any
file. This is fixed now. Thanks to Gerhard Pircher for his testing.
- system failure requesters are now centered on the screen
- rewrote TagList handling
- when using the same asl requester several times each requester had the
name of the first request set, instead of a new one. Thanks to Gernod
Schomberg for that hint.
39.4 (16.07.2001):
- added tool ShowReqs. This one will print a list which process allocated
which kind of requester
- when using Asl->RT mode AslToRT will fall back to Asl requesters if some
unsupported functionality of Asl is used (custom screen modes, custom draw
modes, etc). If you don't want that but see the RT requesters
nevertheless, then use the OVERRIDE option to force AslToRT to use
sub-functional RT requesters.
- the filter functions should now finally filter correctly. Many thanks to
Gerhard Pircher for his constant testing.
- new option CENTERTEXT
- added some security checks to avoid invalid default filenames
39.5 (03.08.2001):
- font and screenmode requesters never returned a successful selection due
to some changes made in the last release (ASL -> RT mode). Thanks to Guido
Mersmann and Klaus Just for reporting this bug.
39.6 (23.08.2001):
- file requesters didn't use the old style IDCMP and filter functions. This
is fixed now. I don't know which programs still use these obsolete
functions, but nevertheless: it is working now.
- AslToRT was exiting immediately when using the ALL option and either
arp.library or req.library was not installed. This is fixed now. Not
installed libraries will be ignored now, even if the corresponding options
are specified.
- emulated Asl file requesters didn't accept empty file selections, even if
you selected a directory. MakeCD suffered from this, because you had to
selected at least one file to make MakeCD recognize your directory
selection.
39.7 (03.10.2001):
- file requesters didn't keep their directory buffer in ASL -> RT mode. This
is fixed now.
- when operating in RT->Asl mode the inital drawer was the same as the
requester title. At least this bug appeared with PerfectPaint. Thanks to
Stefan Martens for his hint.
- when operating in RT->Asl mode the inital drawer contained a trailing "/".
Thus PerfectPaint was not able to load a picture, because it seems to
build the complete path itself instead of using dos/AddPart(). Thanks to
Stefan Martens for his hint.
39.8 (02.04.2002):
- AutoRequest() and EasyRequest() now use the underscore character to
highlight hotkeys for gadgets. Very few programs seem to use this, as
intuition doesn't support this!
- the ReqTools patches produced a wrong rtFileList for asynchronous
requesters. Thanks to Stefan Martens for his hint.
