Ok I will explain better. I have a GUI app. The user loads samples (the rows), my app performs calculations on samples and for every sample give as output thousands of values (the columns). Samples could be from tens to hundreds of thousands. Columns can be tens to thousands. Every column is an attribute of the sample defined by a unique name. After calculations the app/user should be able to search for one/more samples (or for one/more columns) getting all/some values for the sample/column. Briefly I need to be able to rapidly get some values from this huge data matrix. I have two scenarios, both are possible, depending on calculations type: 1. all the columns (the number/type of attributes to be calculated on every sample) are defined by the user before performing calculations, so I know the total number of columns before starting the calculations. Actually I use a sqlite db that I define before calculations started. I create as many tables as I need where every table has 200 fields. The samples are stored in a table, every sample is a row. The attributes are stored in all the other tables (every sample has a row in every attributes tables). 2. The number of columns can vary from a sample to another. The number of columns/attributes for every sample is known only after calculation is performed on that sample. The total number of columns/attributes is known only after all samples are examined/calculated. During calculations I need to modify the number of columns. Using sqlite is quite annoying since I need to alter tables when a new column occurs also closing all the queries, modifying the insert queries and so on. During a calculation process thousands of columns can be created and need to be added. The app can be splitted in 4 different tasks: 1. load of samples (then the user can look at samples, load new samples adding to existing ones..); 2. calculations (can take seconds, minutes, hours depending on the number of samples in the batch and on the number of attributes to be calculated), the user can leave the app working - no interaction, the user is just able to stop/pause the process; 2. calculated data analysis (interactive), the user can perform analysis on data (charts, data views, data manipulation [average, standard deviation...]...) (this should be as fast as possible, data retrieval from the db/datasheet fast); 3. save of calculated data to a txt file/spreadsheet... (not necessarily all calculated data will be saved by the user). The user should also be able to delete/remove samples/columns or add samples/columns. When doing a with a 64 bit program it might be possible and appropriate just to use an array and have the OS do the dirty work of virtual memory management, using a huge swap partition. My app is actually compiled both on 32 and 64 bit.

[Lazarus] TAChart : not reading the OnMarkToText event handler from lfm ?
Hello TAChart devs, on Lazarus 0.9.30 r29749 FPC 2.4.2 i386-win32-win32/win64 it seems the TAChart.AxisList[1] (Bottom) is forgetting to read the OnMarkToText assignment from lfm (excerpt below) item Alignment = calBottom Marks.AtDataOnly = True Title.Visible = True Title.Caption = 'Date' OnMarkToText = Chart2AxisList1MarkToText end (i.e. when starting Lazarus or reopening a project, the OnMarkToText event is empty in the Object Inspector, which leads to a problem if the form is modified, because the assignment is lost and has to be reinstated by hand) Shall I bug or is it fixed in later release(s)? (I guess it's not worth to create example app, try this: - put a TChart on a form - add 3 items to AxisList (left, bottom, right) (this is the order I have them at) - in object inspector go to Chart1, AxisList, 1 - Bottom - change the Title and other properties to it (see above excerpt of lfm) - add a function to OnMarkToText event - save project, compile, etc, - close project/ close lazarus - reopen project / launch lazarus - the title and alignment and visibility is preserved, event OnMarkToText is NOT.)

Thanks.
I realized that this may not work for me. Because I need to compile the
project under both Linux and Windows, and then I need 2 scripts in the same
place :-(
Anyway, I tested with the simplest pre-build script:
git describe --always > REVISION.INC
Then in my program I added:
msgs.Lines.Add('GIT HASH: ' + {$I REVISION.INC});
Unfortunately, it does not compile, the error I got is:
unit1.pas(831,50) Error: Identifier not found "c25d546"
It seems that this directive does not load the include file as simple
string??

If using a relational database, I would also propose that solution. Messing with columns each time is just not what they're designed for. Additionally, if you ever need to scale it up or store data in a database server: different dbs have different limits on max number of columns, performance may suffer when you have a huge amount of columns etc. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

maybe have your script do :
echo "constgithashfrominc : string = \'" > REVISION.INC
git describe --always >> REVISION.INC
echo "\';" >> REVISION.INC
at the implementation section, under const directive do:
{$I REVISION.INC}
and then
msgs.Lines.Add('Git HASH: '+constgithashfrominc);
(i.e. so that you are going to have
const githashfrominc : string = 'whatever';
)
Or have it as resource string (it was mentioned on this list once upon a time).

Yeah, compared to MSEide, Lazarus project build settings are a bit
historic or limited.
To get around problems with scripts vs batch files for cross-platform
use, I found it is better to implement my "scripts" as FPC console
applications. Then simply execute the console application where I would
have used a script. I found that creating such console apps are actually
a lot more powerful that batch files or bash scripts, because I have
full use of the Free Pascal RTL, FCL and whatever else I need.
> Anyway, I tested with the simplest pre-build script:

If you run the 'git describe' from the command line, you would see the
output is simply the "version information" (no constant definition or
string quotes). So you need to place it in your source code with an
identifier as the Pascal language requires. So you need to do something
like the following in your code.
const
cGitRevision = '{$revision.inc}';
Then in your program, use the constant instead.
msgs.Lines.Add('GIT HASH: ' + cGitRevision);

This won't work, because the string takes precedance over the directive.
But you could use the data2inc tool that cones with FPC to convert the
returned data to a include file with constant.

Probably why my original version build script generates the whole line
with identifier.
What about the following...
const
cGitRevision = + {$revision.inc} + ;
Or are expressions not allowed in constant declarations either? Anyway,
I think we gave enough hints for the original poster to find a suitable
solution. I was never pro to spoon-feeding programmers. ;-)

Re: [Lazarus] gtk 3 header
Thats because the files were generated with the introspection files from those two versions. It's pretty easy to generate any version needed for the bindings using the gir2pas program in the Lazarus CCR Regards, Andrew Haines Marco van de Voort wrote: >On Wed, Mar 27, 2013 at 09:53:05AM +, Mark Morgan Lloyd wrote: >> > Was browsing the GTK site a bit, and saw that for recent GTK3 >versions there >> > seem to be Pascal headers? >> > >> > http://www.gtk.org/language-bindings.php >> >> With the link pointing at >http://wiki.lazarus.freepascal.org/GTK2_Interface > >The link of "pascal", yes.

Re: [Lazarus] Limit to the number of forms in a project?

Are your forms created at run- or design-time? They are created at design time. I suppose that I should actually be creating them at run time. I think that the right question is about automatic form creation (on app start) or on demand. I'd let the first form be auto-created, and in its FormCreate handler it creates the other form, before using it or its components. The shared components (list...) also better are moved into a common unit, where they can be created during program initialization. This initialization can reside either in the unit initialization section, or in a routine called from a splash screen, or in the main form creation handler.

Re: [Lazarus] Debugging fixed strings in UTF8 encoding
As you could see in my previous examples, Lazarus shows the content of variable string correctly, no matter how the symbols are encoded. So there is no need in special encoding options in Watches. The point is that when IDE evaluates the string content, there is a difference for it whether the string has variable of fixed length. After all, strings are ordered sequences of characters and should be recognized very very similar. I think it is a bug, and it seems to me that it can be fixed with minimal changes.

I thought {$I revision.inc} is similar as {$I %DAT%}, but apparently they
have different semantic.
