Re: [lazarus] Error: Invalid Free Pascal Source Directory

[Chris Kirkpatrick]

Source files will be in /usr/share/fpc ... or somewhere close to that 
(you may have to dig around  a little!)


In general, Lazarus will be in the directory in which it is installed, 
fpc compiler will be in /usr/bin (or there will be a symbolic link from 
/usr/bin/ppc386 to /usr/(local)/lib/fpc/$version/..., make sure ppc386 
is pointing to the correct version of the compiler), fpc units will be 
in /usr/lib/fpc/$version ... or /usr/local/lib/fpc/$version ... and fpc 
sources will be in /usr/share/fpc ...

Re: [lazarus] LazDoc for preparing documentation files

No pdf at present;

html docs are built regularly and latest snapshot is at

HTML is also visible on-line at http://lazarus-ccr.sourceforge.net/docs/lcl/

[lazarus] LazDoc for preparing documentation files

[Chris Kirkpatrick]

I have been trying out the new functionality of LazDoc in the IDE, on 
which Mattias Gaertner has been working very hard.


Although it is still incomplete, and has been the subject of several bug 
reports, it has a number of useful features. One of these is the 
facility to 'copy from inherited', ie if a property has been described 
for an ancestor, the description can be pasted into the descendant's 
documentation.


I have recently done this for the properties of TGroupBox and TComboBox 
in StdCtrls.xml, pasting in the descriptions from TCustomGroupBox and 
TCustomComboBox (or earlier ancestors such as TControl or TWinControl if 
the property is described there).


It is very easy to use, but I believe we should not routinely use it 
until we are very sure the description in the ancestor class is correct 
and complete, because if we decide that the ancestor's description isn't 
right and we have already made the copies, we will have to retrace our 
steps and change all the descendants' properties as well.



I should therefore welcome some quality control on the work I (and 
others) have done in writing descriptions for the components in the LCL. 
I started with TControl and other primitive components in Controls.xml, 
and worked through Graphics, Forms, Dialogs, and then into the 
components that are actually visible in the IDE, in StdCtrls, ExtCtrls 
and ComCtrls as well as Menus, and have recently started on Grids, 
DBCtrls and DBGrids.


I tried to write the descriptions for the ancestors such as 
TCustomXx before describing TXx. In general I have not provided 
detailed descriptions for the child classes if the properties have been 
described in the ancestors; the on-line help and LazDoc hinting facility 
can trace the description back to the ancestor. We should wait until the 
descriptions for the primitive classes are complete and correct before 
pasting the descriptions into the visible components. (This will 
ultimately be needed for completion of the LCL manual, to make it like 
the RTL manual. At present, if a property is not described explicitly 
for a component, it doesn't appear in the HTML documentation files).


I have also been concentrating on Public or Published properties, and 
recognise that there is still a lot to be done on the Protected properties.


All comments are most welcome.

Re: [fpc-pascal] Re: FCL-DB/SQLDB docs started

[Chris Kirkpatrick]

The list of possible nodes is found, of course, in the FPDoc manual.
Some examples of fairly densely populated descriptions are in StdCtrls, 
DBCtrls, Dialogs, and also in Controls, Graphics, and Forms. In general 
the TCustom components are the most fully described. StdCtrls, 
DBCtrls, Menus  have got large Topic sections with extensive seealso 
references. (A Topic is not, of course, seen by LazDoc, nor is there a 
mechanism for creating one - there is such a mechanism in LazDE).


I have submitted a new bug report.

Thanks. I was searching for some good examples.
Where can I find a list of all possible nodes that lazde/ladoc creates? Or can
you give me some examples, where I can see all flavors?

Re: [fpc-pascal] Re: FCL-DB/SQLDB docs started

[Chris Kirkpatrick]

Hi Mattias -

I note from the bug report 0010686 that you have fixed the immediate 
problem, and on re-building Lazarus from SVN this morning I find that I 
can now save  descriptions from LazDoc in the IDE, and also 
things that I type in other boxes such as .


However the LazDoc  panel does not show text that 
pre-exists in the XML file, and we run the risk of overtyping anything 
that may already be there by using LazDoc, as entries made using LazDoc 
do get saved; similarly, it fails to display the existing contents of 
 fields in the XML file.


As noted before, LazDoc doesn't display formatted text (such as 
underline, italic or bold, marked by word), and I find that if I 
try to copy inherited  titles I don't copy the italic etc words.


For examples see the first few entries in the public/published section 
for TComboBox and TCustomComboBox in stdctrls.


Should I raise a new Bug report, or add this to the existing one?

Regards - Chris

Re: [fpc-pascal] Re: FCL-DB/SQLDB docs started

[Chris Kirkpatrick]

Explanation of some Lazarus documentation terms:

FPDoc - the command-line tool that is part of FPC and is documented in 
the FPC manuals. Includes MakeSkel, for constructing a skeleton XML file 
from the unit source code.


LazDE, aka Lazarus Documentation Editor - an application found in 
/lazarus/docedit/lazde.lpi which you have to compile and use to edit XML 
files built using MakeSkel; this is probably the most useful app for 
doing the documentation, but takes a bit of getting used to.


LazDoc - part of the Lazarus IDE,; if you open a LazDoc window, you 
should (if you have specified the correct paths etc) be able to edit 
documentation XML files in parallel with the .pp or .pas source files. 
I'm afraid I've never got it to work satisfactorily. However, it now has 
a new feature (you don't even have to open a window or anything) whereby 
a hinting pop-up appears if you hover over a keyword etc in your source 
file in the source editor - it searches the source file and the XML file 
to find information about the keyword and displays it (usually the 
 description of the entity). It is very clever, but needs quite a 
lot of tweaking (acknowledged by the developers) to correct it and make 
it fully functional. I use it a lot to check on-line if the changes I 
have made with LazDE produce sensible results.


There is also the option, of course, of hitting F1 for Help while 
highlighting a keyword, in which case you get taken to the appropriate 
SourceForge HTML file, which unfortunately can be several days out of date.


Hope this helps.

Re: [fpc-pascal] Re: FCL-DB/SQLDB docs started

[Chris Kirkpatrick]

Hi John, Joost and Adrian -

As you might know, I have been trying to get the documentation for parts 
of the Lazarus Component Library (LCL) into shape, mainly by putting 
information into the .XML files associated with each Unit, to enable 
generation of .HTML files using FPDoc. Quite a few elements in the LCL 
are now documented to the stage that useful information appears as 
on-line hints when using the Lazarus IDE.


I have started trying to describe some of the Data-Aware components (see 
the DataAccess and Data Control tabs in the Component Palette) but am 
having to delve deeply into the SQLDb and Db files in the FCL in order 
to get information to describe the use of these components. So I should 
very much like to collaborate with you guys in improving the 
documentation of sqldb and fc-db, as well as the stuff in the LCL. I 
agree we should try to use the FPDoc approach as suggested by Joost.


I have been given commit access to the /docs/xml/lcl/ directory in the 
lazarus SVN tree. At present the SQLDb and fcl-db documentation files 
would not appear in that pathway, and we would need to find some way of 
sharing our work on the files - perhaps we need to find a branch of SVN 
to which some or all of us gain access.


I am copying this communication to the lazarus developers list, as they 
are the guys with write-access to the appropriate SVN repositories, and 
may be able to offer suggestions on how best to proceed. I am also 
copying it to the main lazarus mailing list, in the hope that more 
volunteers may emerge!


Please keep in touch and keep the impetus going.

Regards - Chris

[lazarus] Primitive classes in fpc/lazarus

[Chris Kirkpatrick]

Several types and classes that are ancestors of classes in the LCL are 
not found in the RTL, and it is difficult to document the LCL classes 
completely without them. These include many classes with TFPx 
prefixes; some examples are TFPCanvas and related classes, found in 
fpc/packages/fcl-image/src/fpcanvas.pp, fpimage.pp and many others. Is 
there a way of bringing them into the documentation system so that we 
can fully trace the ancestry of LCL components? FPCanvas, for instance, 
has the description of how to do the actual drawing referred to by many 
of the methods in lcl/Graphics/TCanvas.

Re: [lazarus] Search engine for Lazarus and Free Pascal concerned stuff

[Chris Kirkpatrick]

Hi Wanderlan -

I am currently trying to assemble on-line help for the LCL, and if you 
are offering to help, I am delighted!


The tool we use is FPCDoc, which takes the source xx.pas or xx.pp and 
extracts all the identifiers, declared classes and types, procedures and 
functions, etc, and then looks at a descriptor file which we have 
constructed that gives details of the procedures, properties etc. This 
documentation is contained in a xx.xml file, and it is the construction 
of these .xml files that is occupying my time at present. FPCDoc uses 
the original xx.pas file and the xx.xml file to construct HTML files 
that are used to provide the on-line help that is currently accessed 
through SourceForge, but will eventually be included as help-files in 
the distribution.


There is a utility called LazDE (for Lazarus Documentation Editor) that 
is quite useful in constructing and editing the .xml files, although I 
do quite a lot of the work using a conventional test editor. Details of 
LazDE are found here:


http://wiki.freepascal.org/Lazarus_Documentation_Editor

and I suggest you read that thoroughly, together with the FPCDoc manual. 
If you want to collaborate in doing some of the documentation, and 
particularly if yuo have an understanding of some of the more abstruse 
aspects of programming, please let me know and we can decide on priorities.


With kindest regards - Chris Kirkpatrick

Re: [lazarus] DataAccess components in lazarus 2.9.24

[Chris Kirkpatrick]

A live CD is one that you put in your CD rive and boot from it; it 
usually contains a distribution of linux, like Mepis, Ubuntu or Koppix, 
which gets installed in a RAMDISK and you can run it without involving 
the computer's hard drive. Good for evaluating software (you can run 
linux on  windows computer, for example) and can also be used to install 
the operating system. You can download the ISO image from the 
appropriate website and burn your own CD, or get the CD for a trivial 
cost from the distributors.

checksum changed means, the compiler found an old ppu.
This can happen, if some files were renamed. Therefore it is
recommended to use 'make clean all' or even 'make cleanall all' after
an svn update.
If this does not work, compile with 'make OPT=-vut > log.txt'. Then
explore the created log.txt.

You might try looking at the on-line help for the LCL. The easiest way
to get there is to put the cursor on a key-word in your editor, and
press F1. Provided yu have an internet connection, you will be taken to
a HTML document describing the item, and you should find plenty of links
to help you, for example, to trace the ancestry of a particular
component and the properties defined in the ancestors.

I don't know if this helps; please be aware that the LCL documentation
for Lazarus is still in a pretty primitive state and needs a lot of work
(do I hear offers of help?), but you can discern the underlying
structure of any components you use.

 Subject: Mouse wheel and Lazarus IDE editor
 To: lazarus@miraclec.com


 Hi,

 I'm using Lazarus under Linux compiled with the GTK1 toolkit.
 Lazarasu v0.9.23 (r11831).   When I scroll the mouse wheel up or
 down, the editor always scrolls down. It seems to happen more
 frequent now than a couple months back.  Lazarus seems to ignore
 the wheel direction and always scroll down.

I have observed this behaviour in gtk1. I find that if the edit window
scrolls the wrong way using the mouse-wheel, clicking the pointer on the
scroll bar itself restores correct behaviour, at least for a while.

FpDoc works OK  from the command line when I remove the quotes, and
generates HTML as expected.

Therefore there seems to be a bug in LazDE, which is inserting spurious
quotes around filenames before invoking FpDoc. Might this be coming from
the file-picker that is used in setting up the 'Build' action in LazDE?

Should I file a bug report about the insertion of spurious quotes in
filenames?

[lazarus] LazDoc

[Chris Kirkpatrick]

I have recently started trying to create documentation for Lazarus,
after a prolonged break.

Running a variant of Debian Linux (Mepis 6.5) I have checked out the
latest SVN for lazarus and fpc, compiled lazde and started trying to
edit. If I run the just-compiled version of lazde and try to open an XML
file that already contains data, the app closes with a message
'execution stopped'. If I run lazde from the command line and try to
open a file containing data, I get a segmentation fault and the
application terminates.

Any suggestions?

I am happy to report that with the latest, final issue of Mepis 6.0 (ie
not the Beta or release candidate versions) Lazarus instals and runs OK
without the above errors. Whatever pathological things were happening
seem to have been cured. I hope other users will have a similar happy
experience.

[lazarus] Gdk-error on launching lazarus

[Chris Kirkpatrick]

Hi folks -

New installation of Mepis 6 (with ububtu kernel) on Toshiba satellite - 
512MB RAM

Latest libgdk-pixbuf-dev from Debian repository
Latest libgtk2

latest subversion fpc and lazarus - both compile OK

on launching lazatus I get the following errors

[EMAIL PROTECTED] ./lazarus
TApplication.IconChanged - TODO: convert this message...no 
implementation in gtk or win32

NOTE: editor options config file not found - using defaults
NOTE: miscellaneous options file not found - using defaults
NOTE: codetools config file not found - using defaults
NOTE: help options config file not found - using defaults

snip

Gdk-ERROR **: BadAlloc (insufficient resources for operation)
 serial 7630 error_code 11 request_code 53 minor_code 0
Gdk-ERROR **: BadDrawable (invalid Pixmap or Window parameter)
 serial 7631 error_code 9 request_code 62 minor_code 0

I have looked for Gdk-ERROR in Google - lots of entries (rather old, 
circa 20001-2003) reporting the error for a random selection of 
applications (SSH, Firefox, dillo, etc) but no bright ideas about solutions.


Any ideas?

[lazarus] Relative paths for Lazarus and FPC libraries

[chris . kirkpatrick]

I quote something I wrote on the Lazarus-CCR Wiki:

 Installing Lazarus under Windows
The current releases of the Windows Lazarus binary packages install very 
easily, and should work 'out-of-the-box'. 

It is even possible to install the whole Lazarus/FPC package on a portable USB 
drive (capacity at least 256 MB), for use in environments where you are not 
allowed to install software on your Windows workstation or where you haven't 
got administrator privileges. You do have to be a little careful about 
adjusting the paths in the compiler and environment options and the fpc.cfg 
file. It may also be necessary to keep the directory for test compilation on 
your portable drive. 

DOES ANYONE KNOW HOW TO SET UP RELATIVE PATHS IN THESE TAGS AND FILES, SO THAT 
THE ADDRESSING WORKS WHEN YOU MOVE THE USB DEVICE TO ANOTHER MACHINE WHERE IT 
HAS A DIFFERENT DRIVE LETTER?  

It would be helpful to be able to make a single entry in the Environment 
Options and Project Options rather having to change between E:\... and F:\... 
if I move my USB drive from one windows machine to another.

Any ideas?
Regards - Chris
