Anyway, the linked demo seems to be about a very particular case of auto-renaming, Notice that identifiers are different, though with the common structure. An actual analogue for FPC/Lazarus would be an option to rename 'TMyClass' to 'TMyNewClass', while simulatneously updating variable names lile 'FMyClass', 'AMyClass', 'myClass'. -- Alexander S.

Differences: - instant typing is more direct, less typing, more eye candy - dialog provides options to reduce scope, for example when doubling an identifier - dialog provides check for duplicates, for example when renaming will create a conflict - instant typing is only possible in small scope. rename something in all dependent sources can not *easily* be done in real time. conclusion: in place renaming can be done for simple things like an identifier in a script or with a *lot* of effort in bigger scopes.

Re: [Lazarus] Interesting TextMate and RedCar feature
Lets say uo have a method inside a big class. You renamed it from RetriveData to GetData, now every place that uses RetriveData that belongs to that class is changed to GetData, and it does so while keyup, so you do not need to start looking for all of the changes or to discover that on line 100,004 it was not changed, i don't know why. It also changes strings that uses the name, so if you have 100 debugging line of writeln (I sometimes have), it also changes the string. but if you change the string on your own for something else, it will not be applied in feature changes. I hope it is more clear.

The .lpk concept is static, not dynamic like Delphi. This means the designtime code is hard linked into the lazarus binary, and the runtime packages are hard linked into the final binaries.

Re: [Lazarus] TFilestream raises exception class External SIGSEGV
Thanks for all the suggestions.
It was indeed nothing to do with the code I'd posted but had to do
with a subroutine which added elements to a dynamic array.
I rewrote the subroutine and it now works fine.

Re: [Lazarus] revision numbers of each SVN tag?
It seems to me that in this discussion of tags vs. branches collectively we are not in disagreement about what tags are, what they mean, and how they were intended to be used. What disagreement there is seems to be in how to manage a release. Specifically, the process of tagging a release and whether that process should be atomic and immutable or whether it can be adjusted, as necessary. If the tool allows tags to be changed, then some see that as a useful option for adjusting a release that was, at first, incorrectly tagged. Others see such an action as a violation of the proper process for managing releases. So, please let's talk about the discipline of managing releases. If a branch has been designated as ready for release it should be tagged and announced. If that process was faulty - for whatever reason - what should happen? It seems to me that the answer to that question should be decided *independently* of the capability of the tools being used and also separately from the amount of effort involved. In other words, doing the "right thing" is always the correct choice and we should work toward making that easy to do. ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

Nowhere it says that a tag should be set in concrete to last Well to me and most other developers a tag is "a snapshot in time". And if you wanted something to move in time and merge, that is what branches are for. Why else would they have tags and branches? If they were meant to be used the same they would just as well just have created a feature called branches - and that's it (no need for tags). 'tags' have a different meaning to 'branches'. Everybody understands it like that and the documentation explains it like that. But Lazarus doesn't differentiate between it. Well you guys did in the past, but since last few releases tags are now handled like branches. So why do you you guys still bother with tags, just use branches then! At least then users will know to periodically do a 'svn up' on a stable branch. That's how I see it, but now that I know you guys treat branches and tags exactly the same, now I know I need to periodically do a 'svn up' no matter where I am in the repository (and even if it doesn't make sense to me). :-) Regards, - Graeme - ___ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

Quite sure you are trashing the stack in the "stuff" part,
maybe an array access ? Pointers ? Do you have range checking enabled
?
In the other hand, use of a TFileStream to read byte by byte is
overkill.

You miss the point, namely that a 'tag' is just a convention between people. Nowhere it says that a tag should be set in concrete to last unaltered for eternity. Every versioning software available provides a means to set a 'tag', and leaves it up to the users how to interpret 'tag'.

Tags should be created after a release has been announced. Before that, a Branch should be used. I have no idea if SubVersion supports deleting or moving tags. I know under Git I can delete or move tags without problems. What worries me now with the current tags in Lazarus, is that they don't have a clean history (specific snapshot in time). You wouldn't expect to do a 'svn up' after you checked out a tag - so some users might be missing those extra commits / merges. You also can't re-tag by simply using the last merged revision, because the history is not sequential any more. I'm not sure what would happen if you created a new branch (using original revision of tag) and recreated what some of those tags do, then re-tag the branch and then delete the branch... Can you do that? The joys of tags and branches under SubVersion! :-( In future I would recommend using branches and when a release is announced, then only create a tag.

Remove the tag and tag again? Or is deleting a directory under tags not allowed in GIT either?

So you cannot simpy use r18898 for the tag. I noticed that... Doesn't that defeat the point of tags??? Branches are used for merging things. Tags should be set in stone - a snapshot at a specific point in time. Now Lazarus developers do not distinguish between tags and branches. :-( How long before a Lazarus tag is not merged to any more?? This strange usage of tags makes any mirroring near impossible (or a lot more work). I still think merging to a tag is wrong though. Maybe I'll just use the base revision number the tag was created on and be done with it.

Re: [Lazarus] TImageList.AddMasked not working with TBitmap.PixelFormat := pf32bit
Hi Mark, Thank you! The reason I need to use pf32bit is that I manipulate the raw image, and I access the pixels as integers. I can't do that if the image is 24 bit. I actually don't care about the Alpha channel in this case. AScanLineImage:=TLazIntfImage.Create(0,0); AImgFormatDescription.Init_BPP32_B8G8R8_BIO_TTB(Images.Width,Images.Height); AScanLineImage.DataDescription := AImgFormatDescription; for Y :=0 to AScanLineImage.Height-1 do begin Ptr := AScanLineImage.GetDataLineStart( Y ); for X := 0 to AScanLineImage.Width-1 do begin AColor := TColor( Ptr^ and $FF ); if( AColor = clWhite ) then Ptr^ := AGlyphColor else if( AColor = clGray ) then Ptr^ := ABorderColor else if( ASecondaryArea and ( AColor = clRed )) then Ptr^ := ABorderColor else if( AColor = clLtGray ) then Ptr^ := AHalfToneColor else if( AColor = clBlack ) then Ptr^ := AButtonColor AIntfImage.CopyPixels( AScanLineImage ); ABitmap.LoadFromIntfImage( AIntfImage ); Images.ReplaceMasked( ImageIndex, ABitmap, InvertColor( AUniqueColor )); As you can see I need this so I can access the pixels fast as a raw image, and need to get the image back. This is significantly more complex in 24 bit image, so the need for 32 bit image being added as masked is obvious.

For instance, lazarus_0_9_26_2 is based on 18716, and r18269 got merged resulting in r18898. So you cannot simpy use r18898 for the tag.

[Lazarus] revision numbers of each SVN tag?
Hi, I forgot to pull in the 'tags' when I mirrored the SubVersion repository to Git. I would like to tag them now, but need to know what revisions was used for each tag. Based on the following URL, is the "revision" column next to every tag the revision numbers I am looking for? http://svn.freepascal.org/cgi-bin/viewvc.cgi/tags/?root=lazarus Regards, - Graeme - ___ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

Yet I don't understand why thos +4 was added here. There is of course not a complete fix, because I have no access to 64 bit windows.
