About the default file:
The defaults are compiled into the IDE.
I know, but that is part of the problem. And it shouldn't be compiled
into the IDE. At the moment as soon as you start the IDE for the first
time, those defaults are written the users profile directory and into
a file called lazarus.dci. Now if the next version of the IDE has new
defaults, the users lazarus.dci is not updated. Defaults should not be
copied to the users profile directory, they should live in a
objectpascal.dci file in the Lazarus install directory. This also
makes it easier to for contributors to find the code templates and
email patches for updates.
Yes, lazarus.dci is an exception and should be changed to follow the
other settings - defaults will not be written to disk.
The IDE has a 'secondary' config path, where pool admins and package
maintainers can put default configs. A secondary config file is
copied to the user's config directory, iff no user config exists.
i.e. the configs are not merged.
I get the idea, but I have never seen this in real life (as far as I
know).
For example the windows installer sets the fpc search path.
The linux packages and OS X packages use the secondaries too.
What is the name of the secondary user config file? I always
only have the one lazarus.dci file in my ~/.lazarus/ directory. I have
searched my $HOME/.lazarus/ directory and I only have one .dci file.
When the IDE starts it writes the primary and secondary config
directory to stdout.
If no primary and no secondary config exists, the IDE uses its
defaults. So there is already a chain of defaults.
I think adding a further default file only complicates things and
will not solve much.
Maybe I misunderstood your comment about secondary config files and
that it relates more that just to .dci files.
I'm thinking in line of something like Project Templates - a directory
with default code templates that the IDE reads. You have the default
template .dci files for various languages (html.dci, objectpascal.dci,
etc..). If the user did not create any custom code templates, no .dci
files are in the lazarus profile directory (~/.lazarus) as it only
uses the ones in the Lazarus install directory. That way if you add
new code templates like your latest one ('ofall' enum template), you
simply need to patch the objectpascal.dci file and on the next update,
everybody will have it. The lazarus profile directory should just
store custom user created code templates.
The internals are little bit more complicated but from users pov you
are right.

Re: [Lazarus] Packages and file loading
On Tue, 5 May 2009 15:35:13 +0200 Lord Satan reimg...@web.de wrote: Hi everyone, I have a problem with the package I am writing. I have some non-pascal source code which my package must load at compile or run time into a TStringList. But as there is nothing like a $PkgDir macro There is one: $PkgDir(asmodaypkg) I don't know how to find the files at run time. Include files would be my only option at compile time which I don't like as they need at least a token, which means that every source line must be in quotes which makes it impossible to use syntax highlighting for the non-pascal code. Of course I could just put the source into my pascal code but that would be cumbersome, ugly and not easy to maintain. You could create lrs files from arbitrary files: compile tools/lazres.lpi to create tools/lazres ./tools/lazres your.lrs your1.something your2.something ... You can update them manually or write a script/program and execute that before package compile. So as a last option I wanted to copy my non-pascal source files after compilation of the package to a known directory (the plattforms config dir for example). So I wrote a little console app to do that just to realize that I cannot add a program to my package. At the moment I am at a loss what to do now. Is my only option to call fpc myself in the 'after compilation step' of the package compilation to compile my copy tool and after that call the tool to copy the files? Maybe this works for you: Create a package (e.g. yourtool), add the source of your program, uncheck 'use unit'. Then put the command to compile into the 'after compilation step': fpc yourprogram.pas -FE$PkgOutDir(yourtool)/ and check 'Scan for FPC messages'. Then add yourtool as requirement to your main package. Whenever your main package is compiled, the yourtool package is compiled too, which automatically compiles your tool.

If the code indeed has an error, then it must be fixed. And code-completion will not work until it has been fixed. - If it was simply highlighted, then the user will (at some time) have to go there by hand. So that (imho) is less convenient. And the position may not be in the visible area, so the user would not notice. Or the user may have continues to type, that usually makes line highlight disappear. - On the other hand, the current behaviour triggers an unexpected jump, and (for me) it always takes a second or two, to figure out what just happened. So what other options are there? Ideas: - code tools display a drop-down, but it simply has an entry, pointing to the error. The entry can be selected (cursor-down-key; then enter) and you jump to the error location. Continue typing, or pressing escape would keep you at your current location. Sounds reasonable. We should test how it works. - instead of a drop-down a hint could be shown - we could keep jumping to the error immediately (as current); but make some extra visible hint, what and why happened (display a hint / highlight the word in red / if still within the visible area, highlight the original position too) And maybe give a hint that you can jump back with Ctrl-h.

New figures feature is an excellent addition, thanks Paul and
Mattias!
It already motivated be to fix some stylistic problems in one of my
projects ;-)
A few questions/suggestions for improvement:
1) Where did the name came from? It is totally meaningless for me.
See
http://www.askoxford.com/concise_oed/figure?view=uk
Maybe 'Stylistic notes' or 'Style' or something along these lines?
Not all are about style.
2) What is wrong with published properties without default?
See
http://wiki.freepascal.org/User_Changes_2.2.4#Default_property_values
If a property is streamed without need it
1. increases the size of the lfm
2. makes updating error prone, because even useless properties are
streamed. For example if a property was introduced and later
removed/renamed it is still in the lfm and the compiler does not notice.
The LCL had the last case a few times in the last years and every time
you have to check all lfm files. Therefore the LCL has a built in list
of ignored properties.
3) I also like that codeexplorer options are now integrated with the
common dialog, however:
3a) Maybe 'Enable figures' checkbox should be moved to or duplicated
on the 'Figures' page?
Yes. But I'm biased about duplicate or move.
3b) Maybe option 'parameters', lice line/procedure counts, should be
placed near the corresponding checkboxes?
3c) What is the reason for 'search char constants' option? I think it
should just be always on.
IMO char constants like #10, #13, 'a' or ' ' don't need to be
listed.
3d) I think '' (empty string) should be added to the default list of
ignored constants.
IMO no one wants to see empty string constants in this list, so no
need for an option.
4) A few wishes/feature requests:
4a) 'Empty procedures' should not trigger if the procedure has comment
in the body,
to take care of a common idiom:
procedure TMyClass.Proc;
begin
// do noting
end;
The figures are hints, not warnings.
I already found with this feature some empty methods with comments that
were useless and could be removed.
4b) Add 'Unsorted procedures' similar to 'unsorted members'
I rarely have seen units where all procedure are sorted alphabetically.
Same for enums, types, variables and constants.
4c) Add 'Empty begin..end' block, probably with the same check for the

So point 1 is correct as they are a collecion of numbers figures Still, maybe they would be better named as statistics? (maybe analytics ?) I would call them IDE Hints or Code Hints. But Figures are also ok for me. My main point with the name is usability. The name should convey at least something about the named object to an unprepared reader -- this is an important rule both in programming and interface design. So yes, 'code hints', 'analytics' -- anything suggested in this thread is better than 'figures'. (Not 'statistics', however, which, by the way, would be another interesting feature) I thought about 'statistics', 'hints' and some more and IMO they are all misleading. The new section should sum up and/or list all kinds of noteworthy numbers, places, lines, structures and facts of the current unit, that don't fit into the other categories. These combine several different types of categories like: -unoptimized code/left over: e.g. empty methods -code formatting: e.g. unsorted members -readability/needs refactoring: e.g. long procedures, unnamed constants -comments: e.g. todos -... About 'statistics': statistics are about summarizing and interpretation. None of the current categories fit into this description. About 'hints': Theoretically you can define 'hint' very generic: some message about a pascal source. But then the term 'hint' becomes almost meaningless and every time a user user reads about 'hint' he doesn't know whether it means fpc hint or lazarus hint. Just like the word 'package' has more than five meanings on this mailing list. IMHO the term 'hint' has already enough meanings. Modelmaker has a similar feature called 'live metrics', which fits, because they mostly list code formatting and readability categories. But IMO the category 'code formatting' is questionable. All other categories list things, that need some manual attention - the programmer must decide if and how to change it. OTOH 'code formatting' can be applied safely. If you don't like long lines, then you need a tool to break them. When such a tool exists, you don't need a tool to show where the long lines are, you just need a flag: this unit needs code formatting. Instead of adding code explorer categories 'unsorted procedures' it makes more sense to improve the jedi code formatter and its lazarus integration. In fact, I added the 'unsorted members' categories just as demonstration and speed test. Another argument for 'figures' is this: At the moment the items are listed in the tree. Eventually the lists should be moved to a second tree below, where some context buttons are shown. Additionally this would waste less space and update time. Then the current tree will only list the available categories and the total numbers, which is afaik often called in English 'figures'.

It is totally meaningless for me. See http://www.askoxford.com/concise_oed/figure?view=uk Hm. I'll quote that: figure, noun: 1 a number or numerical symbol. 2 an amount of money. 3 a person’s bodily shape, especially that of a woman. 4 a person seen indistinctly. 5 an artistic representation of a human or animal form. 6 a shape defined by one or more lines. 7 a diagram or illustrative drawing. 8 (Music) a short succession of notes producing a single impression. Not one meaning correspond to 'a hint about possible problem in the code'. Maybe 'Stylistic notes' or 'Style' or something along these lines? Not all are about style. At least it will give user a vague idea what it is ;-) How about simply 'hints'? See my other mail why not using 'hints'. 2) What is wrong with published properties without default? See http://wiki.freepascal.org/User_Changes_2.2.4#Default_property_values If a property is streamed without need it 1. increases the size of the lfm 2. makes updating error prone, because even useless properties are streamed. For example if a property was introduced and later removed/renamed it is still in the lfm and the compiler does not notice. The LCL had the last case a few times in the last years and every time you have to check all lfm files. Therefore the LCL has a built in list of ignored properties. These are all good arguments, but _against_ the removal of 'default default' property values. IMHO the FPC's team decision is wrong, but I think it is too late ;-( Now I have to to bloat my code with 'default false' lines, which were not necessary before. Both ways are not optimal, but now it is at least Delphi compatible. I see the reason for the hint now -- but I think it should be made a FPC warning then. A warning will annoy more than it helps. 3b) Maybe option 'parameters', lice line/procedure counts, should be placed near the corresponding checkboxes? 3c) What is the reason for 'search char constants' option? I think it should just be always on. IMO char constants like #10, #13, 'a' or ' ' don't need to be listed. Maybe, but how about #34 or 'ё'? Char constant may be just as magical as any other ;) That's why it is optional. 3d) I think '' (empty string) should be added to the default list of ignored constants. IMO no one wants to see empty string constants in this list, so no need for an option. But it _is_ shown now. Where? 4b) Add 'Unsorted procedures' similar to 'unsorted members' I rarely have seen units where all procedure are sorted alphabetically. Same for enums, types, variables and constants. Well, same for methods and properties. True. Although private sections are mostly created by class code completion, which sorts. Does LCL have one unit where 'unsorted members' list is empty? IMO alphabetical sorting makes only sense if you have no obvious logical sorting, OR if you prefix every member, so that alphabetically and logically sorting produce the same results. Still, this list is IMO useful and so it is for procedures. See my other mail why such things are better be done elsewhere. 4c) Add 'Empty begin..end' block, probably with the same check for the comments as in (4a) 4d) Add 'Single statement in begin..end block' 4e) Add 'Too many nesting statements' and 'Too many nesting procedures' 4f) Add 'Line loo long' with default limit of perhaps 80 or 90 characters. 4g) Add 'Incorrect indentation' for the cases where indentation does not correctly represent statement nesting.

So you probably mean 'stylistic nazi'. Well, yes, actually I am ;-) ;) And you want the IDE to be a stylistic nazi like yourself. Well in some way I understand you. I don't like macros and I will eventually add a category to list all macros. But IMO it is more important to provide a tool to help fixing these things. Which means for the examples you gave ...

Beware: The algorithm does not check recursively (e.g. the inherited initialization sections) and the .lpr file contains a lot of 'unused' units. For example the thread manager, the memory manager or the 'interfaces' unit of the LCL. If someone uses this dialog and simply removes all 'unused' he will make his program unrunnable.

In some years you think the bugs are fixed, and then they come back. You have been warned: Don't use the imp sections. I thought this was known: http://wiki.lazarus.freepascal.org/DesignGuidelines This is the first I here of this. I was always taught to limit the usage of the Interface section's uses clause, so you can prevent circular unit issues. So is FPC the opposite of Delphi in this regards? No, but the problem is caused by the way fpc stores info in the .ppu Somehow it is possible that the checksum of the interface part stored in the .ppu is affected by the implementation section. When editing sources this can lead to strange results, the compiler might think in some cases an interface is changed or not. When Lazarus started we put a lot in the uses section of the implementation part. When some source was changed, sometimes a 3 or fourtime compile attempt was needed to compile the while LCL, since everytime the compiler thought a unit was changed whil it was not. Restarting compilation (and keeping the existing units) in most cases resulted in a compiled LCL. To avoid this and to make the LCL usabole as library, most unit cirles were removed. One way to ensure that is by putting all uses in the interface section. I have used FPC since 2.0.2 under Linux and Windows and haven't had any issues. I limit the usage of interface uses clause as much as possible. I believed that is why the smartlinking works so well with fpGUI - I can create a GUI application that is only 340KB in size. It might depend on how you compile fpGUI. Anyway, back to the subject, I cannot imagine why FPC when smartlinking makes a difference between interface and implementation uses. Especially if you use an external linker, like on linux. Marc Doesn't it require anyway recompilation of all lcl units with -CX option (smart linkable) ? Btw a little different question : what is needed to allow lineinfo reading stack trace from external file (in case of exception) for example of the name corresponding to exe name but with different extension. FPC can now dump debug info into such separate file. Such feature would be very useful as compilation option for example. Write a lineinfo unit that supports the external file.

This is usually tested with if AControl is TWinControl then If a TContainerControl that is not a TWinControl has childs this test will break. Then it would be possible to have lightweight panels, where currently TPanel or similar TWinControl descendants have to be used for grouping controls together. Delphi compatibility is not broken by such a layer. When the layout management is implemented by a LayoutManager hook, as is already used for DockManager, less (memory) resources are required for typical (button...) components, which do not normally have child controls, but inherit all the data members and other bloat from TWinControl.

Panel = group of controls You create the groups in MiG via the properties. So, yes, you create nested groups, but you can not access the groups itself. This has pros and cons. MiG layout is a flow/table/rule based layout manager - like gtk. You avoid fixed positions and define everything relative. This avoids overlapping and gives good adaption to various themes and fonts. Contrary to the nesting rules of gtk, MiG uses hundreds of properties and flags. The learning curve is therefore quite steep. MiG solved the complex setup with parameters in text list format. So it is great for source code (means: less typing), but it is hard to create a good graphical designer, let alone an intuitive one. I hope you have some good ideas. * Auto resize of components so translation text NEVER gets clipped. I have fixed things like this a 100 times in Lazarus, until the next person edits something in that form, or somebody changes something in the widgetset code. With LCL as used in Lazarus IDE, such things are always broken. 1. Can you give the bug report number for the broken layouts, where the translation overlap in the IDE? 2. You can overlap in MiG too. * No over lapping components (a constant issue in Lazarus IDE) bug report? * Automatic button order based on the platform - built into the layout manager. No extra components required like the ButtonPanel in LCL. ... instead it needs some extra properties for that. It is semi automatic. * Automatic border and spacing widths based on the platform - built into the layout manager. eg: Mac OS-X has bigger form borders that Windows, GTK etc.. Yes, that's an advantage of rule based layout managers. * Totally screen resolution independent. Max / Min and Preferred components sizes are taken into account. Well. Which layout manager does not take Min/Max/Preferred into account? ;) * DPI independent. * Unit sizes can be specificed in %, inches, cm, pixels, mm, etc.. * The original Java MiG Layout is toolkit independent. It's very simple to add new toolkit support. I hope to make the port the same. Great. * Built-in debug mode, to help with layout design and debugging. Do you mean the red and green borders? That does not help much. IMHO a good designer should visualize the dependencies. Like the guide lines in Lazarus but MiG's hundreds of flags need much more. .the list goes on! ;-) Yes, the hundreds of flags and properties is a problem. The syntax may look strange in the beginning, but it's quite easy to learn. Also you would probably only use a handy full of syntax commands to complete most layouts. The rest of the supported syntax is for more advanced designs and features, but not required to be able to use the layout manager. It is like the many linux daemon config files. You can setup a server with a few lines, but you never get a good gui. The more the gui supports, the less intuitive it becomes.

LCL still has many features missing compared to MiG Layout. If a control does not provide good Min, Max and preferred size, then MiG layout will fail too - it can only be as good as its input. It's true that the current LCL properties are only pixel based and have no properties for cm, inches, percentages, That's a feature of MiG.

The generated LFM file definitely looks like any LFM file (it has a component, with properties first then other nested Components) To store a property that is a component and which is not owned by the Lookuproot (form, datamodule, frame) you must set the csSubComponent flag in ComponentStyle.

Re: [Lazarus] TAChart: double-buffering (issue 0012377) questions

In issue http://bugs.freepascal.org/view.php?id=12377, reporter said:
Painting to an Bitmap and paint this on the Canvas would be much
faster
This assertion is, of course, incorrect. I assume that the reporter's
problem is actually that the TChart flickers when repainted.
The flickering is caused by two sources:
1) The TChart is TGraphicControl, so Parent control erases chart's
background before every repaint.
2) TChart itself draws directly to screen, first clearing the canvas.
First source obviously needs fixing, and I attached to the issue a
patch which fixes it.
The only caveat is that TChart is now TWinControl -- can it lead to
some undesirable consequences I am not aware of?
All direct TWinControl descendants must be implemented in all
widgetsets.
You can use TCustomControl.
The second source can also easily be fixed by double-buffering, but
before I do that,
I have two questions:
1) TWinControl.WMPaint already contains double-buffering code, but it
is protected
by {$ifdef BUFFERED_WMPAINT}. What is the reason of this? Is there
some ongoing work to implement double-buffering globally?
It was an idea to implement double buffering, but it does not work on
all platforms. Gladfully most widgetsets have double buffering
themselves.
2) If double-buffering will be implemented in TAChart itself, it will
have some negative
performance impact. So, should I make it optional via DoubleBuffer
property?
Please try first TCustomControl.

Here is another issue. When working on a program involving multiple
units, it may turn out that the Use AnsiStrings was not set
consistently.
Students are advised to enable this globally in the Compiler Options,
but they sometimes forget. Some (given/generated) units also contain
their own {$H+}, others don't.
Is this a student bug or an IDE bug?
This may give rise to inconsistencies
(usually flagged by the compiler, but not understood by beginners).
When you change Compiler Options later, and then do Run, the relevant
unit may not be (re)compiled, because its source code did not change.
One is required to do a Build All first. But a beginner will not be
aware of this.
Yes, that's why the IDE adds -B when the compiler parameters changed
(except for search path changes). 0.9.26 has this feature. 0.9.24 not.
Is it possible to have the IDE suggest a Build All when doing Run,
if the Compiler Options were changed after the previous build?
It does.
Please provide an example, where it does not work.
Or even better have a three-way global setting:
When doing Run and the Compiler Options changed after the previous
build:
* Always do a Build All -- this would be better for beginners
* Always ask to either Build or Build All (the latter as default
choice)
* Always do a Build -- this seems to be the current situation

If not, is there a list of what needs changing? I have not seen one. Personally, I do not know how to compile Lazarus at all, so certainly would not now how to compile without cwstrings, and this would be true for anybody meeting lazarus for the first time on a recent Mac, which will be either 10.4 or 10.5. I think a lot of Macs are still on 10.4. As Felipe already said: Formerly compiling on Mac was quite difficult because of the many linker issues. The FPC team did a great job, so there are only a few issues left. As I said: Normally a user should not need to know about cwstrings. Maybe I will implement a more 'dynamic' widestring manager.

If it is extended with the path it would probably have the same problem: components outside the lazarus directory will be fine, components in the lazarus directory will point to the old one once imported. Again, maybe the solution could be the use of relative paths. Yes, you need a filter option for the import/export.

When you setup a second config directory it needs to know the outside packages. Well, when I switched from svn to 0.9.28, and built it with lazbuild, I ended up with components and the lcl from svn instead of 0.9.28.

By default I need to press Shift to access the numbers on the top row keps, so obviously the standard bookmark shortcuts don't work for me. :-) Programmer Dvorak is a blessing and a pain. It's great for typing source code, but it's a pain with any program that has many default shortcuts. Luckily Lazarus IDE is configurable. I had to sit for a while and reconfigure all my most used shortcuts in Lazarus IDE so they are more comfortable to type. A once off pain, but I'm pretty happy now. :-) Maybe you want to post your dvorak key mapping for laz somewhere.

In detail not when Delphi doesn't remember bookmarks across sessions :-( I see no special advantage in remembering bookmarks across sessions. :-) Since my Delphi 4 days, I have always used bookmarks as a quick way to jump to section of code - that are relevant to what I am currently working on. Tomorrow or a week from now that code will not be relevant anymore, because I will be working on a different section of the project. An IDE should not guess about what is how long important to the user. When I quit today, and want to resume my work tomorrow, I appreciate to have my current bookmarks as I left them. I also would like persistent folding. I second that. Such session information is a big time saver for me. Also, I can see a potential problem with Lazarus's persistent bookmarks. What if I set bookmark 1 in Unit2.pas. Then remove (delete) Unit2.pas from the project. What happens now if I press Ctrl+Shift+1 while I am in Unit1.pas? Nothing. If a unit is closed its bookmarks are removed. When the unit is reopened the bookmarks are restored (unless you changed them). You can see the active bookmarks in the popup menu of the source editor. Depends on the context. Breakpoints, bookmarks and folding can be seen as project specific, but they also can be seen as file specific. Every IDE will have to specify the implemented handling, depending on reasonable thoughts. The best solution would make everything configurable by the user, with according save/recall features ;-) Mattias ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
