[Lazarus] ZeosLib and FPC 2.2.5
Hello,
I'm trying to install ZeosLib 6.6.5 on Lazarus 0.9.29 using FPC 2.2.5, and
it has a problem with the current code:
BaseFieldTypes: array[TFieldType] of TFieldType = (
ftUnknown, ftString, ftInteger, ftInteger, ftInteger, ftBoolean,
ftFloat,
ftFloat, ftBCD, ftDateTime, ftDateTime, ftDateTime, ftBytes, ftVarBytes,
ftInteger, ftBlob, ftBlob, ftBlob, ftBlob, ftBlob, ftBlob, ftBlob,
ftUnknown,
ftString, ftString, ftLargeInt, ftADT, ftArray, ftReference, ftDataSet,
ftBlob, ftBlob, ftVariant, ftInterface, ftInterface, ftString,
ftTimeStamp, ftFMTBcd
{$IFDEF FPC2_1UP}, ftString, ftBlob{$ENDIF});
FPC claims that it ends prematurely and more items should be added.
Has anyone solved this error (it will be easier then do a parameter by
parameter checking by hand) ?
Thanks,
Ido

Current trunk has: (db.pas)
TFieldType = (ftUnknown, ftString, ftSmallint, ftInteger, ftWord,
ftBoolean, ftFloat, ftCurrency, ftBCD, ftDate, ftTime, ftDateTime,
ftBytes, ftVarBytes, ftAutoInc, ftBlob, ftMemo, ftGraphic, ftFmtMemo,
ftParadoxOle, ftDBaseOle, ftTypedBinary, ftCursor, ftFixedChar,
ftWideString, ftLargeint, ftADT, ftArray, ftReference,
ftDataSet, ftOraBlob, ftOraClob, ftVariant, ftInterface,
ftIDispatch, ftGuid, ftTimeStamp, ftFMTBcd, ftFixedWideChar,
ftWideMemo);
That seems to mostly match. Maybe the FPC2_1up construct fails?

Re: [Lazarus] ZeosLib and FPC 2.2.5
Thanks, I updated the records (with the FPC version) and it compiles
properly, but it seems that ZeosLib is not a 64 bit ready.
It uses pointer of integer and I experience a lot of weird behavior
regarding bookmarks.
I require to use Firebird and perform tasks on it. SQLdb does not push the
transaction to the database, so I do not know what else to use in Lazarus 64
bit.

No. The sync (for fixes branch) is not a automated process, but I try and update it once a week (normally Mondays). If somebody urgently needs a fix they can contact me directly or simply cherry-pick the patch they need from "upstream" to there local "fixes" branch. As of 15 minutes ago, the "fixes 0.9.28" branch in Git is synced with SubVersion fixes branch. PS: Please note this "manual sync" process in ONLY for the "fixes" branch. Trunk in SubVersion is automatically synced every 15 minutes with Git's "upstream" branch. Reason for "manual sync" of fixes branch: - Now for the long answer... :-) * SubVersion does not distinguish between tags and branches. * SubVersion does not keep a good history of when branches are started and from what commit they started (I think this is fixed in latest SubVersion) * Git's svn support is not perfect. So based on the above points I decided to manually sync the "fixes" branch. If I automate the "fixes" sync, then the Git repository grows much bigger than needed because (I think) it actually duplicates patches (commits) for the branch and not reuse them. So I simply get a changelog from my previous sync to current revision in fixes branch. I then cherry-pick those revisions into "fixes". This does not increase the Git repository at all because it reuses the original patch (commit). And yes, I do allow for custom changes in fixes branch, which were not merges (like changing the revision number for a release). -- Regards, - Graeme - ___ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

I've added the queries into the InsertSQL nd UpdateSQL however it seems like it is using the SQL code and make "it's own" update and insert (I know this because the index is set to not null, and in the select statement I retrieve it, but on Update and Insert it raises an exception that the ID is mandatory and is null).

[Lazarus] ASCII - IBM's (old) extended character set
Hi, Does Lazarus have a unicode conversion table for this ASCII character set? See url. http://www.web-wise-wizard.com/programming/ascii-ibm-extended-character-set.html As you can see from the url, the characters below Char(32) is very different to standard ASCII table or the ASCII table with CodePage 437. I'm reading old binary data files that used the IBM Extended ASCII characters in text content. At the moment I simply do a the following to replace certain characters. For example, what we know as the standard ascii (bell character), was the a bullet character. s := StringReplace(s, Char(7),'•', [rfReplaceAll, rfIgnoreCase]); Times have changed!

Re: [Lazarus] syncro mode[Re: Auto indentation]
I just stumbled on the below if SrcEdit.EditorComponent.SelectionMode<>smNormal then exit; will not prevent the indent if an smColum mode block is inserted. The mode of the data inserted has nothing to do with the mode of the current block. And after the insert, there is no block, therefore it can not be checked. the new event will explicitly report the mode. The advantage of OnPaste is that it will also be called for quick-paste (middle mouse) which indenter currently is not. Only thing that will not call anything, is drop-drag-edit (can be addressed later) Martin ecPaste: begin if not CodeToolsOpts.IndentOnPaste then exit; if SrcEdit.EditorComponent.SelectionMode<>smNormal then exit; if LogCaret.X>1 then inc(FirstLinePos); if LogCaret.Y=LastLinePos then dec(LastLinePos); if LastLinePos -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Re: [Lazarus] Auto indentation
Graeme Geldenhuys schrieb: Source code formatting is a matter of taste. Regardless of the internal storage of horizontal formatting, the result does not please everybody. Yes I know that, but elastic tabstops is so far the best formatting option I could find. And I would definitely us it for my own projects - if it existed in Lazarus. Also, as I mentioned, the gEdit plugin that enables elastic tabstops has a option to automatically do conversions. So you can work with elastic tabstops enabled, but when saved, the file gets converted back to using spaces. What will happen when you commit your changes? Will everybody have to work with your formatting, casted into spaces? Also elastic tabstops touch on a point that most formatting arguments (tabs vs spaces) do not pick up on. Formatting MUST be done by the Editor in a visual only way - same as what editors visually do Code Folding, or drawing Procedure Divider lines. Code Folding markers or Procedure Divider lines are not something in your actual code content. This "eye candy" is applied over your code and *not* in the source code itself. That's acceptable, even if I have no use for such eye candy. Same thing should apply to code formatting, which is what Elastic Tabstops does. You press the Tab key, which inserts the char $09 - nothing more! Now the editor does the formatting for you, but doesn't modify the source code contents to do it. I'd agree with different tabstop codes, so that the formatting can be undone or suppressed at any time. I'd appreciate a version control system that separates formatting from content, and thus would track only changes in the content, regardless of whitespace and line breaks. Then switch to Git. It has had this option since the beginning of Git (a few years back). Maybe you didn't understand my point? essential changes. Furthermore the *language* should allow for automatic formatting, and the OPL has certain deficiencies in this area. Rubbish, you just said formatting is a personal thing! Plus the compiler doesn't give a crap what formatting you use, as long as the code syntax is valid. This is exactly how it should work. Formatting is definitely NOT a language feature. Automatic formatting has to know about the language, in order to know where to indent and outdent blocks, or how to build columns of other items. If somebody wants to have formatted tables, he'll have to insert formatting *instructions*, so that the layout can be restored later - but where should such instructions be stored? This has been done for years in C programming. Have you not noticed the first line in many C source code files, it specifies the tab width in a commented line. I never saw that, but what's the use of such indicators? But that is also not ideal, because now you are forcing YOUR formatting onto other people that open that file. Again, Elastic tabstops solves the problem nicely, because you personally define the formatting of a Tab character ($09) in your editor - *without* needing to modify the source code to get formatting correctly. This only applies to tabs at the begin of a line, where formatting also can be done automatically. If you are still confused as to what Elastic Tabstops do, then re-read my earlier post that explains it. Sorry, it doesn't explain much. It shows how the output could look like, if everything works. Each line in that example only uses two Tab characters, but based on your customizations of elastic tabstop settings, the formatting will be different between users, but still align correctly for everybody. Where "correct" reflects the opinion of the inventor. That applies even if you use a variable width font too! So you are no more limited to only coding with monospace type fonts. That's right, from the technical view. Nonetheless the use of proportional fonts is limited in programming, in detail with tables and numbers. At least all (hex) digits should have the same width. With small characters, like 'i', it's hard to position the cursor for insertion or deletion. Moving the cursor through consecutive lines can become a nightmare :-( DoDi -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

So you can work with elastic tabstops enabled, but when saved, the file gets converted back to using spaces. What will happen when you commit your changes? Will everybody have to work with your formatting, casted into spaces? If any commit converts tabs to spaces, then elastic tabs do not solve any problem any more or less than any other tab handling does. In this case the stored text has only spaces. If you check it out again, and wish to edit it, you need an editor, that detects where those spaces should be tabs (magical guessing according to your taste) Such conversion (to spaces / from spaces) can be applied to any form of tabs that you have in your source code NOTE: The conversion of tabs to spaces can be defined in 2 ways: 1) tabs a converted to an as many spaces as needed, so the look on the pc of the converter does not change 2) tabs and consecutive tabs (as well as consecutive spaces) are converted to a single space nly (except in strings or other white space sensitive areas) The first solution does not solve anything, as the checked in text still expresses the format of the one writer who converted it. => Format is still part of the content, not applied to a content The 2nd form will work (exceptions see further down) but requires are really good formater for any one wanting to work with this text Same thing should apply to code formatting, which is what Elastic Tabstops does. You press the Tab key, which inserts the char $09 - nothing more! Now the editor does the formatting for you, but doesn't modify the source code contents to do it. I'd agree with different tabstop codes, so that the formatting can be undone or suppressed at any time. Tab stops in the source (white space insensitive area / outside strings etc) are formating. They are formatting, because they cause different layout, unless they can be ignored / handled same as spaces After all Graeme would only need a single (or 2) tab char in the source, in order to align comments at the end of several lines I need maybe between 1 and 10 tab stops per line so my editor shows the comments aligned (using normal tabs) If all editors are to handle them elastic, then they carry format into the content content, and thus would track only changes in the content, regardless of whitespace and line breaks. Line breaks are interesting. Since some people write: if a then begin or: if a then begin the line break itself embeds formatting into the content. If you want to archive, what you describe (format free content) then all whitespaces (including tabs, newline) must be stored as simple space (except some basic interpreters, which have linebreak as part of the language) Applying tabs and linebreaks is eye candy, that your editor should apply on top of the content. Linebreaks could be used for paragraph like grouping of statements, that represent a logical entity in your code, yet are not presented as a procedure of their own. --- I may have shlightly disconnected from reality while writing the above Martin -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

See url. http://www.web-wise-wizard.com/programming/ascii-ibm-extended-character-set.html As you can see from the url, the characters below Char(32) is very different to standard ASCII table or the ASCII table with CodePage 437. I'm reading old binary data files that used the IBM Extended ASCII characters in text content. At the moment I simply do a the following to replace certain characters. For example, what we know as the standard ascii (bell character), was the a bullet character. s := StringReplace(s, Char(7),'•', [rfReplaceAll, rfIgnoreCase]); Times have changed! I remember those smiley face characters in a old pac-man game I used to play. :-) Regards, - Graeme - Hi Graeme, I don't know if it helps, but the Windows font "Terminal" contains exactly all those 255 ASCII characters... cheers, Paul -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
