I have done a quick test and ran : ctags *.pas which has successfully generated the tags file for all the pascal files in the current directory. I've opened the pas with vim, and i can go on a procedure call and press ctrl+] which jumps to the definition of that procedure. Ctrl+T jumps back . In my case the procedure was defined in the same source file, but there is no reason for this mechanism not to work with functions defined in another file. The version of ctags that i've used is : Exuberant Ctags 5.5.4 (http://ctags.sourceforge.net/) Cheers, Adrian Maier _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

I just stumbled on Ctrl-Delete the other day. I must lead a sheltered life. I am more spoiled with Delphi than I am with Lazarus because of one little add-in that works with Delphi: http://www.cnpack.org It's a suite of productivity tools like GExperts for those of you who haven't seen it. Someone suggested it to me on borland NG's a while back. Lots of cool features, but to me the best reason for installing it, is auto suggestion code insight like C#/VS2005. It's like hitting Ctrl-Space automatically. You start typing tstr and assuming you have SysUtils in your uses clause, the suggestion box pops up automatically with contextual suggestions like : TStringList TStrings ... and it works with declare variables, keywords, etc. You hit tab or enter to accept the suggestion and one less word to type. For actual coding, I have not seen a better little feature than this as far as productivity is concerned. 1. Speeds typing in two ways: 1) You obviously don't have to type the entire keyword, variable, etc out and 2) No shift key necessary to get nicely camel cased variables. 2. Improves readability of code and lessens coding mistakes.

The main bottleneck of an OPF is the database access, how the OPF builds DMLs, Yes, that's the easy part. do object cache, lazy loading, bulk retrieving, etc. That's where things become interesting, because you have to figure out how to interface with your non-OO db, aka relational-DB, without incurring any duplicate overhead.

If I understood you correctly, this means build an OPF tied to an specific database, and this isn't a nice approach. I know it does not sound nice, but an OPF should not be considered an independent layer, but rather as a wrapper/converter/adapter to the non-OO db, much like the connection broker, only the connection broker output is a tdataset wheras the OPF should give you direct access to your native objects. In the current design I have: user - mvp - data type - opf engine broker - connection broker (tied with) db engine You can change every part without changing the others. If you implement the OPF as a pluggable system, then you may do the same. A small overhead do exist actually, I don't think it's small, unless you mean small apps which deal with textual data only. For large apps that deal with blobs, the overhead may bring down your system. and the way to remove it is writing a connection broker that doesn't depend of a db suite like SQLdb or Zeos, and that doesn't depend of the tdataset as well. If you do it this way, then you are actually implementing proxies, and proxies should not be used unless there is a need for them like for border-gateways, because proxies add overhead. What you may want to try is to refactor the OPF, dataBroker, and dbConnectionLib into their respective layering components, and then recompose a native OPF wrapper based on those layering components.

Interesting and amusing. an OPF should not be considered an independent layer, but rather as a wrapper/converter/adapter to the non-OO db, An OPF and its connection brokers consist of an independent layer that binds objects of an oo model and a storage mechanism. A small overhead do exist actually, I don't think it's small, unless you mean small apps which deal with textual data only. For large apps that deal with blobs, the overhead may bring down your system. No, small overhead even to applications that handle large objects. There are three points to consider: 1. the real bottleneck is in the database and in the network; 2. moving data between layers doesn't mean big overhead due to refcount of ansistrings or other managed objects; 3. lazy loading of objects and attributes mixed with bulk retrieving. and the way to remove it is writing a connection broker that doesn't depend of a db suite like SQLdb or Zeos, and that doesn't depend of the tdataset as well.

Dominique, I think you can enter -XM under Custom options on the Compiler Options' Other tab. Glad to hear that you got it to compile.

Sometimes it is, eg building smart DMLs and smart strategies to retrieve data, using prepared statements when possible, and so on. Then comes the client-side, which we can control. Improvements in the client side sometimes doesn't worth the effort. If, lets say, 90% of the time is in the server side and the network, a perfect client side would increase 10% of the performance. The side effect is the complexity to maintain and extend the code. Other improvements that can be made regarding performance is creating threads to perform some slow tasks in the background, while the application answer some key or mouse events of the user. Where is the data cached? Attributes belong to business objects. BOs are reference counted and the ones that wasn't removed from the memory are referenced by a cache that belongs to the persistence service. 3.lazy loading of objects and attributes mixed with bulk retrieving. And how does the app access this object-data? Retrieving its OID through the persistence service. This service will query the cache (binary tree -- todo list) in order to know if the object was already instantiated. If it exist, its address is returned, otherwise the persistence (xml, database, whatever) is queried in order to retrieve information to instantiate such object. and the way to remove it is writing a connection broker that doesn't depend of a db suite like SQLdb or Zeos, and that doesn't depend of the tdataset as well.

I've couldn't pickup it from what was on the wiki.

Re: [lazarus] Using SDL.framework within Lazarus project on Mac OS X
Hi Philip, Thanks again, that does the trick. As soon as I finish this project sometime in Jan/Feb I'll be sure to add stuff to the Wiki. Dominique. Hess, Philip J wrote: Dominique, I think you can enter -XM under Custom options on the Compiler Options' Other tab. Glad to hear that you got it to compile. Maybe you could write up something in the wiki about how to use SDL with Lazarus. Perhaps a small test app to help get folks started.

Thank Felipe and thank you Philip for your patience throughout this thread. Hopefully one last question when it come to passing parameters to the compiler from lazarus. How do I pass the -XM parameter via the Lazarus IDE, as I need to redefine the main function it currently uses? I could not find a tab that allowed me to set this up.

[lazarus] Fix for PrintersDlgs error in current snapshots on Mac OS X...
Hi all,
I sent the following fix to Jesus a few days ago, but I have not
heard back so don't know if he received it or if he has checked it in yet.
Basically in PrintersDlgs you have code that looks similar to this just
after the implementation.
{$IFDEF LCLCarbon}
uses Unit Names Here
{$ELSE}
{$I cupsprndialogs.inc}
uses Unit Names Here
{$ENDIF}
This should really read
{$IFDEF LCLCarbon}
uses Unit Names Here
{$I cupsprndialogs.inc} // Moving it here works
{$ELSE}
uses Unit Names Here
{$ENDIF}
I currently do not have access to a patch facility so I can't provide
one this time, so I hope someone can move that include to fix this error
and check it in.
Thanks,
Dominique.

Basically, I sent you this patch with instructions on how to apply it
and recompile Printer4Lazarus pacakge, and the last message I
received from you was that it didn't work.
Anyway, in r12807 I commited the patch that I think should fix the
issue.

The code in r12545 doesn't look like this ...
This should really read
{$IFDEF LCLCarbon}

{$I cupsprndialogs.inc} // Moving it here works
{$ELSE}

{$ENDIF}
Maybe that would be an error under *nix. The whole LCLCarbon can be
well removed, but well, lets the code as it is until carbon printer
support is implemented, which seems to be work in progress by the
way.

Hmmm... the rdb or the suite that access the rdb caching data means extra resource usage I think, on behalf of performance. Exactly. But you wouldn't want to do this caching twice. Ok, I had a quick look through the docs, and it seems that you have the design tightly coupled to the MVP. The MVP _is_ the design, or even better, is the presentation framework. Oh, I meant the OPF design. Is it possible to isolate the OPF from the MVP? Is there a way to directly attach LCL objects to your OPF? You don't need to do this. Eg: create a form without code or non-visual components, bind BO attributes and components in a single line, and the MVP will do the rest for you using informations from the model. Sure, this is great when you are working with a disconnected presentation layer like a web interface. But for native apps, you don't need this, because your presentation layer is already connected to your model via TForm. So what we need is for a TForm to directly connect to the OPF without going through the redundant MVP framework. Is this possible? BTW, as I said, the MVP would be great for a disconnected presentation layer like in web development, so it would be really useful to have an MVP to WebPresentation proxy. Does your MVP include this feature? Also, I tried to compile the demo, but it gives this error: ObjectModel.pas(23,3) Error: Only class which are compiled in $M+ mode can be published Thanks! -- Al _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: [lazarus] Fix for PrintersDlgs error in current snapshots on Mac OS X...
Hi Jesus,
I sent you an email last week ( 6th of November to be exact ),
confirming that this fix works.
I've been away in New York, so could not send you a confirmation
earlier. This was all mentioned in that email. Obviously you did not get
it which is what I feared, hence why I sent the email to the list.
Dominique.
