[Oorexx-devel] Anyone using a shared source tree between Linux and Windows ?
Hello, My main environment is WinXP, and I run occasionally PuppyLinux in VirtualBox when I want to compile under Linux. For now, I have two separate source trees. I can mount the WinXP source tree under Linux, but can't build because the CR-LF brings troubles (starting with bootstrap :-). Maybe it would work better if the source tree was managed by Linux and made visible from WinXP. So, I'm just curious to know if anyone is successful in sharing the source tree...

There are quite a few that were not implemented becaus they really did
not make much sense for a mutablebuffer. For example, the arithmetic
functions (min, max, sign, abs), the various conversion functions
(d2c(), etc.), datatype(). There might be others, but those are the
ones the spring immediately to mind. I believe the set of "string"
functions is fairly complete, but even here there are exceptions
(abbrev(), the base64 encode/decode).

Ok, here's a souce string" "a"
Use chagestr to replace the characters starting at position 6 for 5
characters with "123"
Now try this with overlay()
Now do you see the benefit of replaceAt() :-)
To do this operation without replaceAt requests two substrings (or a
parse operation, which is the equivalent) + two concatenate
operations. This requires the creation of 4 objects to get one
result. This can also be done with a delstr()/insert() combo, which
only creates one extra object, but replaceAt() does it in one shot.
replaceAt() is particularly useful with mutableBuffer if you're using
it to make editing-type operations.

IdentityTable is used mostly for situations you need to keep track of
actual object instances rather than relying on "equality", which may
not be the same. The interpreter uses this internally, for example,
to keep track of the objects that have a pending uninit() operation.
In this situation, it is important that the table be able to use the
object as an index even if the "==" method of the object claims that
this object is "equal" to another object.
At lot of the uses of this are pretty esotericbut when you need
it, you need it!

Re: [Oorexx-devel] New Feature Questions
replaceAt() does a replacement of one substring with another string. Thus
"abcdef"~replaceAt(" ",3, 3) -> "ab ef"
is correct. It replaces the 3 characters beginning at postion 3 with
the string " ". The resulting string is shorter than the original
string.
In the second example, the replacement position is beyond the original
string. This version is essentially the same as using overlay,
because there are no characters snipped out from the original.

OK, thanks. Still not clear about these examples for replaceAt:

I would think that the first would give "ab f", i.e. 'cde' replaced

There is no such concept of "packages avaiable to a rexx object". Package visibility refers to code instances, not the objecs to which code happens to be attached in the form of methos. An individual object may have methods that are defined with many different levels of visibility. Again, this is a question that can't be answered because it does not map to any concepts in the language. Rick On Sat, May 9, 2009 at 9:04 AM, Rony G.

[Oorexx-devel] Question ad callback (Re: A few questions ad ...
Thanks for clarifiying. In my current state of the code for BSF4Rexx for the new APIs it becomes possible to refer to ooRexx objects from Java. To do that a RexxProxy is defined at the Java side referring to a ooRexx object, which is registered (and locked) at the native layer. There are two fundamentally different modes of operation in BSF4Rexx: one is using external functions only, the other one (the preferred one, because it makes things much easier for the ooRexx coder) requires a package named "BSF.CLS" (this will also change a fundamental setting at the Java side of the respective BSF4Rexx engine and expects data from thereon to be encoded in a special way). Now, if the public routines and public classes of "BSF.CLS" were available at the time the ooRexx proxy was created, I would need to execute a public routine from that package before sending the Rexx object the message received from the Java side. So the question would be: how can I figure out for an ooRexx object what package definitions are available for it, if the call does not come from Rexx, but from JNI ? In this scenario neither GetMessagePackage() nor GetRoutinePackage() are available [in principle it should be possible that a RexxProxy on the Java side can be used for another RexxInterpreter instance spun off via a different engine instance there]. ---rony -- The NEW KODAK i700 Series Scanners deliver under ANY circumstances!

For example, the arithmetic functions (min, max, sign, abs), the various conversion functions (d2c(), etc.), datatype(). There might be others, but those are the ones the spring immediately to mind.

Ok, here's a souce string" "a" Use chagestr to replace the characters starting at position 6 for 5 characters with "123" Now try this with overlay() Now do you see the benefit of replaceAt() :-) To do this operation without replaceAt requests two substrings (or a parse operation, which is the equivalent) + two concatenate operations. This requires the creation of 4 objects to get one result. This can also be done with a delstr()/insert() combo, which only creates one extra object, but replaceAt() does it in one shot. replaceAt() is particularly useful with mutableBuffer if you're using it to make editing-type operations. > > 3) While I believe I understand the difference between a Table and an > IdentityTable, can you give me an example of when I would need to use an > IdentityTable rather than a Table? IdentityTable is used mostly for situations you need to keep track of actual object instances rather than relying on "equality", which may not be the same. The interpreter uses this internally, for example, to keep track of the objects that have a pending uninit() operation. In this situation, it is important that the table be able to use the object as an index even if the "==" method of the object claims that this object is "equal" to another object.

They don't have the concept of "public_routines" and "public_classes" Libraries don't even define "classes", only the code backing methods that can be used in class definitions. A ::requires LIBRARY merely ensures that an external library is a vailable and is loaded befere the program starts executing.

Is this > advisable? Routine objects are just ooRexx objects, so the question of storing a reference of that object with another object is no different just because it happens to be a Routine object. If you can obtain the routine object instance, there are mechanisms that allow you to store it. The big question is what are you really trying to do here?

Again, this question has no meaning. There is no library object you can query, Libraries do not define classes. The routines are part of the global environmemt. If you need the library, just ensure the bloody thing is loaded and make the calls. If you wish to make the load dynamic, there are many mechanisms available to do this.

Do we know of any methods that are NOT in both or should it say "...has all..."? 2) Can you explain when one would use the String Class replaceAt() method rather than overlay() or changeStr()? 3) While I believe I understand the difference between a Table and an IdentityTable, can you give me an example of when I would need to use an IdentityTable rather than a Table? 4) How are the new utility classes for sockets, MIME and SMTP provided, i.e. where are they in the distribution, and what does one need to do to make use of them?

Given the following scenario: 1. an interpreter instance is created with RexxCreateInterpreter(), loading a native library "ABC" via the options argument, all loaded routines will be visible from thereon to every program that gets called 2. using CallProgram() for some program "d.rex" which loads a library "DEF", then ends 3. using CallProgram() for some program "g.rex" which loads a library "GHI", then ends 4. using CallProgram() for some program "j.rex" which loads a library "JKL", then continues to run and via native code there will be callbacks to ooRexx that occur via another CallProgram() from native code Questions: 1. in 3. above: would all public routines and public classes that got loaded in 2. (e.g. via a "::requires DEF") be visible in 3. ? 2. would the program in 4. see all public routines and public classes of the previously loaded libraries DEF and GHI ? 3. for a callback from native code to Rexx in 4. above, which public routines/classes would be available to the callback, how would one be able to use (actually to fetch a reference to) those available public routines/classes? 1. Scenario: the only thing available to native code currently is a reference to an ooRexx object that got stored in the native interface layer in an earlier call from a running Rexx program. 2. It would be possible to fetch a reference to routine's package object and store that with the ooRexx object and then on callbacks use that. Is this advisable? 4. if this is possible at all: how could one determine from native code whether a given library is loaded and if so, how could one get access to its routines and classes? ---rony -- The NEW KODAK i700 Series Scanners deliver under ANY circumstances!
