RE: [lazarus] Google's Android OS :)
Im not realy a core guys my specialty is to create programs (GUI) or
SOAP services. Im more a user then a core designer so im not realy
familiar with this.
But im sure it will aid somehow to bringing te Lazarus project to a
other level.
Im stil waiting for the day I can have everyting I need to recompile
osFinancials with Lazarus.
I gess I also need the time to reinvest to see if this is posible yet.
You know how it goes when you have users Bugs first :-)

Hello Pieter,
Yes i am from holland.
i am experienced but ia newby in the lazarus field.
So i start with the grammar.
simply because i got a lot of teaching about grammar at school. i
downloaded the pascal grammar of the web. and run it strough antlrwork
and checked the pascal grammar.
this was the result.
[08:54:51] Checking Grammar...
[08:54:53] warning(200): java.g:777:5: Decision can match input such as
'0'..'9'{'E', 'e'}{'+', '-'}'0'..'9'{'D', 'F', 'd', 'f'} using
multiple alternatives: 3, 4
As a result, alternative(s) 4 were disabled for that input
so thats interesting !!
i have no idea what it means but i will find.
because i did study study 30 years ago
so i have to refresh my knowledge.
i have attached the pascal grammar in this post.
regards
Met vriendelijke groet,
Pieter Valentijn

I was told early in my career that if you can't find at least 1000 defects in a complex software project then the testers aren't doing their jobs properly :-) Hey, it's a ver. 1.00. That already tells users to expect one or two things that don't work correctly to be sorted out in ver. 1.10 More importantly, we have a deadline approaching Systems-2007 promotion time. so we should be looking to exploit all the hard effort so far and show off a bit maybe we can even find some commercial sponsors to help with funds to do it... right ? I have some serious objections to the way this discussion is going. It does seem that catchy logo's and major version numbers are considered more important than quality of code. IMHO nothing beats quality and as long as lazarus has loads of serious bugs there's no use to take the next hurdle already. Want to speed things up? Then start sending patches. If you can find a sponsor, even better. But the baseline is there's a lot of stuff that needs to be fixed. What good is promoting a non finished piece of software in such a high profile way?

RE: [lazarus] going legal, time for a name change....
So is this already posible ? I mean where do I send my 100 Euro to :-) I want to support your effort. When I forked from Turbocash to osFinancials we also made a foundation to make sure rights etc are not under 1 person but under the foundation name. We did register the name osFinancials atleast in the Benelux (belgium Netherlands and Luxembourg) so in our home we can savely use the name. When it was called Turbocash there was a company here in Holland named Cash that tried to Sew me. It cost me about 1000 Euro's on a good loyer but he wrote them a letter and I never heard from them again. I gess theres not mutch to worry about for you gusy theres not mutch compilers out there and im sure theres non starting today that will use the name Lazarus. Enny judge will recognize the global known name for this compiler. Anny other products using the name does not count as the assosiantion must be in the same brance. (a company called OPEL who sells bread cannot be sewd by OPEL who makes cars. Now if they use the same sign and lettres there mite be a case but purly on the name they can forget. Theres manny companies that bare the last name of there founder. If its not in the same market there is no problem. The problem comes from confunsion with the customer. Getting confused with the compiler you use looks to me like something inposible. And im sure annyone will agree this with me. So keep up the good work guys.

Hi Philip, It should be very little - as far as I can see - it should in fact be working - it just isn't yet (I'll bet it's a small problem though), and then packaged so it can be installed with relative ease. To give more idea -there is some major bug that's making it exit without an error message on launch - dunno what that bug is - that needs to be fixed. The windows client should be able to take connection details from a config file, connect to a postgresql server with an outkafe database, and then log in etc. Virtually all this code is written, it simply needs to be properly ported, packaged and shipped - by somebody with the experience to do so (I work as exclusively on Linux as you do on windows :p ) Of course the packaged version should also include whatever dll's are needed for a windows app to be a postgresql client. Are you up for giving it a shot ? You don't REALLY need a Linux server, you could just set up a postgresql server on windows, load the OutKafe table-scheme and manually generate one user to test with. A.J. PS.

OutKafe comprises basically three parts (this I KNOW is on the website). The postgresql database server does all the network serving, so I don't code any of that, I just interact with it. OutKafe has: 1) A daemon which counts down time on logged in accounts (it's done centrally for security reasons) 2) An administration tool which allows the icafe operator to sell time, create user accounts, reset passwords, define offers etc. 3) Client programs which let a user log in, counts him down and logs him out again. Currently only the Linux client is in a working state. The win32 client is very close - but I need somebody with genuine windows coding experience to help me finish it. There is also a WIFI client very similiar to what you describe below, but that is not very complex and at this stage barely started. I guess I'm not familiar with Internet cafes like this. Usually here the cafe has wireless and you get a login code for your laptop when you buy a coffee. That is common in some countries, here in the developing world the kind with computers hooked up that you buy time on is still very common, for many people such outlets ARE their offices. Having a GPL'd tool to manage them is an important (I believe) way to ensure software freedom in the developing world. OutKafe is the only such tool out there (OpenKIOSK is only partially free software - I'm not aware of any other free projects that are still actively developed though there are quite a few proprietory ones like smartlaunch). Of course the whole thing is also done in Lazarus and is one of the oldest continuing lazarus developments (the original app was started in November 2002, the Lazarus website carried a story on the 3.0 release in May 2005).

Just debug the problem, raise hipotesis about what could be wrong and test them until you find the problem. Check if all parameters are correct, check all the values that go to the function, etc... Just debug until you find out what is wrong. Hello, Felipe! So the problem is solved. I had fixed two files - intfbaselcl.inc and graphmath.pp. Now Ring-Chart is working both in GTK and in GTK2. New files with fixes applied are in .ZIP file that is added to the letter. The main problem was in intfbaselcl.inc. In graphmath.pp I had rewrote PolyBezierArcPoints function - I think it is a good solution - it seems that it is faster and more logical in code. Several checks were removed and some important added. Also, I think it is a good idea to check all graphmath.pp - to move some widely used constants to the top of the file and to cleanup some code. It seems that there may be some double checking inside of it (as it was in BezierArcPoints function). Should I do this work? Best regards, Alexey.

Not for as far as I known, but I think you could either
- use classes with published methods RTTI; there might already be some
code dealing with this; have a look at TXMLPropStorage
- write a program that parses the record declaration and produces XML
read/write functions for these record types

Yes you can use this property to find out things or you can remember your own variabel. the key here is that only 1 control will recieve then key down.

RE: [lazarus] StrToDate error
I agree that when you can you should use TDateTime but there are cases
where string presentation for storage is needed. Lets say we make a
export / import function in a CSV file.
There needs to be a contract on how to store dates (and numbers for that
sake) that is the same.
Displaying to me is best left to the operating system. Now with that
date as a string in to the database this can still be a advantage. Like
for systems that don't always know the exact day.
By representing them in String this can be overcome. Searches can be
done on year and month fairly easy.

The case I have is that variants are used in parce thechnieks and
there cnversion is importamt to the rules. (reporting uses parces and
so you need to go from string to date and from date to string using
variants. Im not sure how this is aranged in Laz but I think in Delphi
its not realy working well.
You should not have to worry about it. You use TDateTime, and convert to
string as needed as the user sees fit.
I don't agree with Graeme's solution: it's not up to the programmer to
decide how the date/time is shown to the user. The user has decided that
for us when he configured his regional/localization settings.
To be able to store date/times without worrying about the settings, the
TDateTime format is used. It's the responsability of the data layer to
convert TDateTime correctly to/from something the database understands.
It's the responsability of the GUI layer to display the TDateTime
to the user in the format HE specified. And to convert anything HE
provides to TDateTime format.
I've been working for 10 years with this principle, in databases which
are crowded with date/time fields (the number of fields runs in the
1000s) and the only problem we ever experienced was when we explicitly
converted TDateTime to string representation using some wrong string. We
don't use custom routines, only the standard Delphi routines.
The previous version of the same application, written in VB, was crowded
with problems exactly because the dates were manipulated as strings
instead of as some native date/time format such as TDateTime.
So IMHO Delphi handles it pretty well. But you must stick to the rules
it
and the user set...

I didn't follow the full thread, so excuse me if this reply is out of
context. Have you guys ever considered using the International ISO
8601 date format. See the following link for a summary:
{ Summary of ISO 8601 http://www.cl.cam.ac.uk/~mgk25/iso-time.html
}
cIntlDateTimeStor = 'mmddThhmmss';// for storage
cIntlDateTimeDisp = '-mm-dd hh:mm:ss'; // for display
I've also created a few helper functions that convert those date
formats to TDateTime, and the reverse.
function tiDateTimeAsIntlDateStor(const ADateTime: TDateTime):
string;
function tiDateTimeAsIntlDateDisp(const ADateTime: TDateTime):
string;
function tiIntlDateStorAsDateTime(const AValue: string): TDateTime;
function tiIntlDateDispAsDateTime(const AValue: string): TDateTime;
Once it's in a TDateTime, any GUI date/time edit component can do with
it as it pleases, though I still show it in the ISO display format.
Even for storing dates in a database, I don't use the DB's native
date/time types, I rather use the ISO storage format and a plain
string field. This way I always know the date formats and no confusion
with date/time delimiters and no confusion with the date parts order
d/m/y, y/md/, m/d/y, etc...
I've been using this in a production environment for over a year now
without any issues.

I dont understand what you mean.
thats the definition of TranslateUnitResourceStrings in my lazarus:
function TranslateUnitResourceStrings(const ResUnitName, AFilename:

what is ,a,b in your changed one ?
these routiones are just for loading translations so its no big thing if

RE: [lazarus] StrToDate error
Well he makes a point on the redability of reports using the ISO date format. I think its all just depending on what you make. If you have a multy coparate miljoin dollar cross global sales system you would want to go for the ISO standard for dates but in most other cases you would just use TDateTime and let the end user display it in his format. I gess it was just the point Graeme was making. I still enjoyed the discussion guys :-) Met vriendelijke groet, Pieter Valentijn Delphidreams http://www.delphidreams.nl -Oorspronkelijk bericht- Van: Michael Van Canneyt [mailto:[EMAIL PROTECTED] Verzonden: donderdag 1 maart 2007 9:00 Aan: lazarus@miraclec.com Onderwerp: Re: [lazarus] StrToDate error On Thu, 1 Mar 2007, Graeme Geldenhuys wrote: Hi, On 2/28/07, Michael Van Canneyt [EMAIL PROTECTED] wrote: You should not have to worry about it. You use TDateTime, and convert to string as needed as the user sees fit. I don't agree with Graeme's solution: it's not up to the programmer to decide how the date/time is shown to the user. The user has decided that for us when he configured his regional/localization settings. Both you and Peter V. misunderstood my post slightly. You don't have to force the user to see the date/time in a certain format. Though we opted for it after a length discussion. Storing the date/time as a string in the ISO 8601 format is forced and allows you to export data to another application without having to try and guess the date format in the new application (mmdd, ddmm, mmdd, etc). You don't need to guess if it's in the database native format ? Once the string date/time is read and converted it to a TDateTime, the GUI can displays it in the way the user specified in their regional settings, but as soon as it goes back to the database or some file, it gets converted back to the ISO string format. So bottom line, the user sees the date/time it the format they prefer. This is the first choice. We opted to follow the ISO 8601recommendation for display as well, to help remove confusion between various date formats in digital or hardcopy form. To me this sounds contradictory :-) the user sees the date/time it the format they prefer. We opted to follow the ISO 8601recommendation for display as well Which one is it ? You can't have both :-) Imagine the following case: The user in USA generates a report with date/time columns as a PDF document. Emails that to head office in the EU somewhere where in changes hands a few times. Now how do we know what date format that report used? Is 02-06-2002 the 2nd June or is it 6th Feb? So when is the deadline for the multi-million dollar contract? :-) If it uses the ISO 8601 format -mm-dd there is no confusion, hence the reason we opted for that format in our applications (display on screen and paper and in storage). So, the user has no choice... ? (not trying to argue here, but your statements seem contradictory to me.

RE: [lazarus] StrToDate error
Wel I gess we all agree on the point that datetime format settings is something where theres a variaty of opinions on how to use it. IT just points out to me that the mater is not simple. If I would ask how to declare a component we would all be saying TMyComponent = class(Tcomponent) end; and agree on it in a instance.

We had similar issues (can't remember exactly what) with Firebird. Hence the reason we now store it as strings. Ok, so there's a bug in the data-layer, db-component or database-server regarding TDateTime fields, so you decided to store it as a string? If there's a bug regarding numerical fields, do you also store them as strings? Or do you fix the bug? (Use another database-server?) MS SQL stores date/time fields in a TDateTime format. (That's why it's such a strange format.) Firebird uses something similar. The client- library has to convert that. If that conversion goes wrong, that's simply a a bug. But understandable, since if you use a simple 'select datefield from table', without using parameters, it'll return the field in a string-format, depending on the database-server settings, the client settings and the connection/transaction settings. The program which retrieves the field, should be aware of that. If it doesn't that's just a bug. It's exactly the same as with your solution: the application has to know in which format the string comes. (in your case some iso-standard) Only the 'build-in'-system is more flexible. You can set the format you want yourself. (including your ISO-standard.) So instead of rewriting everything in string-based fields, you could do a 'set dateformat=iso' or something similar when you open a connection... And third-party software can set it to their own needs...

RE: [lazarus] StrToDate error
Most users here will find this kind of display confusing.
But I agree with the store path. Anny external storae that needs sting
presentation should be in one format or at least s format agreed on. The
case I have is that variants are used in parce thechnieks and there
cnversion is importamt to the rules. (reporting uses parces and so you
need to go from string to date and from date to string using variants.
Im not sure how this is aranged in Laz but I think in Delphi its not
realy working well.

I didn't follow the full thread, so excuse me if this reply is out of
context. Have you guys ever considered using the International ISO 8601
date format. See the following link for a summary:
{ Summary of ISO 8601 http://www.cl.cam.ac.uk/~mgk25/iso-time.html }
cIntlDateTimeStor = 'mmddThhmmss';// for storage
cIntlDateTimeDisp = '-mm-dd hh:mm:ss'; // for display
I've also created a few helper functions that convert those date formats
to TDateTime, and the reverse.
function tiDateTimeAsIntlDateStor(const ADateTime: TDateTime): string;
function tiDateTimeAsIntlDateDisp(const ADateTime: TDateTime): string;
function tiIntlDateStorAsDateTime(const AValue: string): TDateTime;
function tiIntlDateDispAsDateTime(const AValue: string): TDateTime;
Once it's in a TDateTime, any GUI date/time edit component can do with
it as it pleases, though I still show it in the ISO display format. Even
for storing dates in a database, I don't use the DB's native date/time
types, I rather use the ISO storage format and a plain string field.
This way I always know the date formats and no confusion with date/time
delimiters and no confusion with the date parts order d/m/y, y/md/,
m/d/y, etc...
I've been using this in a production environment for over a year now
without any issues.

RE: [lazarus] StrToDate error
Im not sure itds SQL as this is OCI layer finctions it parces params to a prepared SQL statement. They came with a quote that BAAN uses its on format for null dates. I gess they just don't want to write the is not null against the = nuldate. Still I think this should be something the database should take care of. Then I asked them if they could make it a parameter so I can relay on correct date entrys and this guys starts ratteling about the test they would need to preform to make this change.

The space character for a date separator is not part of the enumerated set. It is '-' or '/' for the short date format. With international correspondence, the official date format is usually DD MMM when using English. But the short date format is one of the following: DD-MM- MM-DD- YYYD-MM-DD where the separator is a '-' or '/'. To eliminate this problem in Windows and Delphi I normally read the DateSeperator and ShortDateFormat and save them to a temporary variable, Change the separator to a '/' and set the short date format to mm-dd-. Once the program exits, I restore the DateSeperator and ShortDateFormat globals.

Hi, although I am not a lazarus developer myself, I dare to to add my two cents here... I fully agree with Tom. Quartz 2D is the ONLY future compatible mac way in the moment. For the non-mac people, the problem is follows: You don't have direct access to pixels in Quartz anymore, just floating point coordinates. As I understand some of the canvas methods require pixel access. Yes, and they are slow on all platforms, so no time critical application use them. I have not really thought of this all the way through, but maybe it would be simple to have an offscreen bitmap graphic which acts as canvas and use Quartz 2D to map it to the screen. In this way one would really have pixels to manipulate. Yes, possible. IMO the carbon intf should not use the deprecated API. But the decision is up to the implementer - Tom.

RE: [lazarus] best use of components for mysql query insert performance benchmarking
I gess parameters would be a bit more OO.
So consturct your sql like this.
MySqlCom.sql.text := 'Insert into test(Name) values (:NAME)' ;
Then uses
MySqlCom.ParamByName('NAME').aswhatever = somewhatever ;
This way you only need to set the SQL 1 time.
Don't forget if you set params your Query does not close and open.
So you need to do this.
MySqlCom.close ;
MySqlCom.ParamByName('NAME').aswhatever = somewhatever ;
MySqlCom.open ;
I think this whay you also just pas params and not the full SQL so it
just needs to be parced 1 time by the SQL optimizer (if anny is used).

Onderwerp: [lazarus] best use of components for mysql query insert
performance benchmarking
I'm writing a program to do some informal benchmarking of insert and
query performance using various MySQL storage engines using MySQL 5.1.x
latest beta. I've got it up and running just fine using Lazarus and the
MySQL components. It was a piece of cake.
My question is on what the best way is to do the inserts to get the
truest picture of insert performance. Right now I'm basically
constructing an insert statement string and using ExecSQL to do the
insert. Is there another way (perhaps one a little more
object-oriented) to do inserts other than just piecing together a huge
Insert into table t1 (a, b, c, d,) values ...-style statement? If not,
would I get better performance inserting multiple records with each
statement I execute (insert into t1 values (1), (2), (3), ...
etc.) or inserting one record per statement (insert into t1 values (1);
insert into t1 values (2); etc.?
Any tips you have would be appreciated. I just want to eliminate as much
as possible any performance hits due to the overhead of the tools I'm
using to do the benchmarking, thus getting a better picture of the
performance of the database itself.
Thanks,
Seth Grover

[lazarus] Sugestion tread use for updating forms.
I think the same functions are in Lazarus as in Delphi right ?
i.e.
Somewhere global
var
aThreadLock : TRTLCriticalSection ;
In any procedure that calls the treadlist or tread actions that must
finish before anny other actions take place you can use structures like
this.
EnterCriticalSection(aThreadLock );
try
try
tablo:=TSqlite3Dataset.Create(Nil);
tablo.FileName:='db/services.db';
tablo.SQL:= 'select type_name, server_ip from servers where
id='+ inttostr( record_id) ;
tablo.Active:=True;
type_name:= tablo.FieldByName('type_name').AsString;
server_ip:= tablo.FieldByName('server_ip').AsString;
except
main.StatusBar1.SimpleText:='thread1'+tablo.SqliteReturnString+tablo.SQL
;
end;
finally
LeaveCriticalSection(aThreadLock );
end;
end;
I also gess lazars has the same Synchronize function like the one in
Delphi
There you get this hint tekst
Important: Methods and properties of objects in visual components can
only be
used in a method called using Synchronize, for example,
Synchronize(UpdateCaption);
and UpdateCaption could look like,
procedure ADSLUpdThread.UpdateCaption;
begin
Form1.Caption := 'Updated in a thread';

RE: [lazarus] Gambas
Yes This is cost of sales (when you sell something you dedut the cost price from a balans account and put it on a loss account) This way you know what you made proffit loss. If you buy in goods you don't make a loss you merly exchange cash for goods. When you sell the goods you deduct the cost price. If you do traditional FIFO your cost price mite be to low (and your stock mite look to high) using FIFO is mutch better so the cost of sales is the ammount your last product purchases price was. So you proffit mite be less but its more accurate. In Holland and manny other countries you must select your way of sales cost and stick with that. If you want to change you will have to inform your tax athoitie first and ask permission. Theses are all financials transactions inside The ledger so there also part of the XBRL. I gess XBRL is the global standard so im sure your country also used that in declearing there standards if not they will probably change to this soon. Do you make finnacial software for your market? osFinancials has a verry good basis for accounting. Im sure most of the reports are just a mater of the right SQL and some transformation.

RE: [lazarus] Gambas
Yes the port can be done but it will jest be a lot of work. I am turning all reports to reportman so that needs to be availeble on Lazarus. It now compiles in Delphi 7 and you can create plugins in Lazarus as we connect to Firebird. Do you have anny accounting skills ? Else writing a package is not adviced. I can realy do with people helping met cut the code in to modules so if theres anny takers :-0 That request was a bit odd from Philip it just shows his technical knowledge. I think osFinancials can oneday ron on Lazarus (that will be my end goal) its just not now. Theres mutch structuring to be done in the code to get a better reuseability. We do have a good solid accounting basis and do stock control and cash register systems. Theres links with osCommerce so you can import datat from the webshop and im currently building a plugin for Vtiger so CRM package can be used to get account details and sales (just like the webshop but for diverent markets). The client data gets used a lot so I will use this alternative I wrote to substitute that. Then we have the comercial components that still remain in code. The most work will probebly be the grid (info power) as the relay on the events that grid gives. I think redesiging them is the only option for this but it will be a hell of a job with big impact. I need to sigment the project and currently I use DLLs and fastmm4. Can Lazarus do the same ? The DLL routines can have strings lager then 255 like this type TOSFMenuPlugin = function(AApplicationHandle: Thandle;AConnection:TZConnection; InProcessFile,OutProcessFile :PChar) : TModalresult ; stdcall ; InProcessFile and OutProcessFile can be larger than 255 This would be the only real problem if I cant call DLL's created with lazarus from a lazarus project.

Not the route I want to follow, though would like to use some of their ideas and other ideas from BS/1 Accounting. It happens that I have a strong background in accounting, should you need help. A couple of years ago I was responsible for the accounting of a middle sized firm (something about 1 transactions a day) and for the cost management. There was a lot of transactions in foreign currencies so I gained a lot of experience in that field. The problem I see with an accounting program is the fact that at lower level it has to couple with different laws and forms of taxation, so the greatest work is to build a flexible system that can be easily adopted to the single nation's legislation. I was investigating about innovative ways of handling the business transactions and double entry bookkeeping to discover new ways of doing old stuff and be more efficient (we have computers now, it's stupid to do the same thing that Luca Pacioli did in Medieval times). Very interesting field, but at the end you have to couple with the problems and details of the local legislation, and that really put me off (hope the EU will do more standardisation in the future). You are right however, oop is the way to go and build a strong framework of business classes, combined with an OPF and a good solution to link the business classes to the UI. I've seen a lot of bad code written in Delphi, no tests and validations that were mixed directly with the UI code, completely unmaintainable.

RE: [lazarus] Gambas
So you say its all about marketing? I run a opensource Accounting project and I have the same problem try to attract as manny new user as you can meens you need to market it for that user group. I gess writing to all universities we can get a email adres from is a start but calling someone in your local area is probably the most effective. On call to the right person can set things in motion. I think Lazarus is the best choice for students. But we will need to reache the tutors for that to happen so they can point to the right directions (the Lazarus site :-).

There are hundreds of other open source IDEs, we are all already aware of that. If you have some specific need Lazarus does not attend, or something that it could attend better, and Ganbas does it, then we can talk about this specific feature. And even then, consulting how several other projects solve the problem would be better then looking at only one other project. The page I found it mentioned was one that was speaking of Visual Development on Linux (compared to VB on Windows) and didn't mention Lazarus at all (only some replies to that topic mentioned it, but they forgot to post a URL). From the image they had there about Gambas it looked more appealing than Lazarus (for example when you launch Lazarus [if you don't tell it to open something], is there option to autostart with the File/New dialog? [that should be the default option and have checkbox to not show that at start again]). What I mean is that Pascal is almost as easy as Basic to use (apart from VB's With and Case which are better in my opinion, or ForEach which is missing), and isn't case-sensitive as C/C++/Java/C#/etc. and is natural-language friendly (not have to learn some strange symbols and how to put them together to author a program as in some well-known scripting languages), so it's either that Lazarus is missing some IDE touches to make it more appealing to newcomers, or that it needs more/better PR (e.g. try to post nice screenshots of it to such net discussions that newbies [esp. interested in university students] may come across while searching for what IDE to use) _ avast!

RE: [lazarus] TStaticText.TabOrder
Aha a TMemo with Color=clBtnFace and Border=bsNone :-) when the component's accelerator key must belong to a windowed control for example, on an ActiveX property page I gess they mean that Active X needs every control to have a handel. I have looked at it and it seems the property focused can become true for a TStaticText but theres no visual indication. Tobstop is default False.

Are you sure that wasn't a TEdit with Color=clBtnFace and Border=bsNone ? Maybe I am confusing GTK features and Windows, I am not sure anymore :-) Anyway, TEdit with Color=clBtnFace and Border=bsNone still behaves differently (different alignment, no wordwrap, ...).

RE: [lazarus] LazDoc support inside IDE
I also think lazarus is verry good :-) Theres one feature I realy miss working in the IDE thats the back and forward buttons when you used Ctrl+click on a routine and then you can go back to that place with the buttons. I use this to inspect code and get back to where I left off. Met vriendelijke groet, Pieter Valentijn Delphidreams http://www.delphidreams.nl Thanks for your time explaining it all Mattias. The reason I am interested in the LazDoc (part of IDE), is because I am trying to convince the tiOPF (Delphi) developers to rather use the fpdoc format, for documentation compared to embedded docs between the code. Writing a LazDoc type add-in for Delphi is what I am proposing, instead of using the external LazDoc Editor. Lazarus just rocks, compared to Delphi! ;-) I think I am slowly but surely convincing those Delphi developers to move to FPC and Lazarus. - auto create missing fpdoc entries (e.g. after adding a method to the source). Basically the same as makeskel does, but on the fly for single entries. This is started for attributes and simple elements, but not yet for complex things like classes, methods, types, ... . So what happens when you do the opposite? Eg: I refactored a class and removed a method not needed anymore. My fpdoc xml had documentation for that method, but now that method doesn't exist anymore. Will makeskel notify me that the method is now missing? What happens to the documentation in the xml file? - use package/project fpdoc help when pressing F1. At the moment you have to manually register it via design time packages. The idea is: As soon as the lazdoc search path is set for a package: use it. That would be neat! Creating the design time doc packages are really easy and use them a lot. It works perfectly! -- Graeme Geldenhuys Location: S 34° 03.168' E018° 49.342' http://tinyurl.com/y6lc26 There's no place like 127.0.0.1 _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
