[Lazarus] Lazarus slow on large files
Hi, I was doing some test programming for android. The android SDK unit contains 68000 lines (.pas and .inc together). Opening it in the IDE (by right-clicking an identifier in my sources) virtually stops the IDE. The source of the android include file are drawn, but the scrollbars are not drawn, scrolling or navigating the source does not work, and the IDE is generally totally unresponsive. Only closing the tab again makes the IDE responsive. (and even the closing takes a while). All this is on Linux, GTK, 64-bit, Lazarus from yesterday. Has anyone else experienced similar problems ?

Trim is bad example :) but if you wanted Ctrl+Shift+Alt+Space to expand, e.g.
AnsiReplaceString()
into
AnsiReplaceString('','','')
What would you put as 'empty' parameter for functions that have numeric meaning,

if you expand Divide() to Divide(0,0) and forget to put some meaningful

You do know shift-ctrl-space ?
Which opens a hint showing the possible parameter list(s). That also has the
advantage to work if there are overloaded versions.
I know. Thanks.

only put the comma when the parameter is required.

This idea came when i had to type about ten times a function like this func('',

ctrl+v. This would be only a very subtle behavior. Like every one knows,

This is another flaw in the documentation (system), that it is not properly configurable for the actual user environment. The RTL is almost only documented and pre-configured for *nix (include paths...), so that adding the Windows paths can produce strange results.

so which one is correct?
IMO Integer is a compiler built-in type, and thus it doesn't have a
reference to the current declaration. The same for Char and string types :-(
I already mentioned that flaw, and suggested conditional declarations:
{$IFDEF fpdocsystem}
type
integer = LongInt;
cardinal = LongWord;
...
char = WideChar;
string = UnicodeString;
...
{$ENDIF}
This is on my todo list.
why does basic stuff, eg: 'write' and 'writeln' not have any help at all?
Thanks, I didn't realize that yet. It's for the same reason: these are
compiler magics, for which FPDoc doesn't find a declaration in the source
code, and consequently ignores all such element, even if they exist in the
XML files. See above for possible workarounds.
This is not correct. It has been documented for 12 years at least.
See my direct answer to the orginal post.
where is the help for items like 'PadRight', 'AddChar', 'PadLeft',
'AddCharR' and similar??
I just can't find in which units these are declared. The FCL is only
documented to a small percentage, perhaps these functions reside in such
undocumented units?
remember, we are coming at this as a pure newbie with some coding
knowledge, no books, and an extremely simple background in programing...
yes, much of the basic stuff really does need to be specified ;)
Please create an according FPC bug report, if none exists yet, and hope that
somebody will update the documentation.
It is documented since years, so no need for a bugreport.

You don't like to validate your assumptions, do you?
You're right, the *basic* types (SmallInt...) are not documented, the
*generic* types are. That's why I added IMO, because I was too lazy
ATM to dig deeper into the problems.
rtl/inc/systemh.inc, line 87:
Type
{ The compiler has all integer types defined internally. Here
we define only aliases }
DWord= LongWord;
Cardinal = LongWord;
Integer = SmallInt;
UInt64 = QWord;
One problem is the missing declaration of SmallInt, which makes the
Integer declaration useless.
and rtl/objpas/objpas.pp, line 24:
{ first, in object pascal, the integer type must be redefined }
const
MaxInt = MaxLongint;
type
Integer = longint;
...what causes further confusion. I accept that a documentation
*generator* can not know about the later setting of the compiler mode.
An IDE might know that mode and the target platform, though. But how
should it propagate that knowledge to the help viewer? And how shall the
user know which of the duplicate entries applies?
Please validate first by either checking the documentation by hand
(using lHelp's search) or using IDENTIFER site:freepascal.org on Google.
I trust a user when he says that something doesn't work, e.g. he doesn't
get help displayed for some keyword. Next comes the search for the
reason, maybe a configuration only, or a more general problem. And there
I search in my knowledge base for similar items, but because human
brains work differently from computer storage, my memory may be
misadjusted, but it is not normally plain wrong.

Maybe because the at was introduced rather late by Borland and then they didn't want to break compatibility with code that uses at as a variable or something. until is in the language for a long time (Delphi language, not Pascal language). Same with words like helper, read, write, default, requires, contains. They were all introduced afterwards (though there seem to be exceptions, so it's not easy to decide whether something is a global keyword or a context sensitive one). Correct me, but var until: boolean; does not compile, while var at: boolean; does compile Yes, that is correct. Looking at my message again there might have been a misunderstanding: until is in Object Pascal since the beginning, but maybe the at part was introduced later. Other keywords like helper were also introduced later so instead of breaking working code Borland decided to make them context sensitive. That's my theory for this.

For logging info on nested stuff. have a look at Debugln / DebuglnEnter

Procedure Foo;
begin
DebuglnEnter('now in foo')
try // optional
Bar(Foo());
Debugln('123');
finally
DebuglnExit('leaving foo')

end;
All Debugln in the block are indented with 2 spaces per level (or

So that gives a nice log

Thanks for doing the AVL fix =) I will study it and see if I can substitute FPList in some other projects too with AVL tree. 2012/2/15 Mattias Gaertner nc-gaert...@netcologne.de: The code explorer still needs a lot of time on this unit, because it creates 60.000 nodes and for each node it creates a description. Maybe the descriptions can be created on demand and only for visible nodes. It might be quite hard to do that without affecting accessibility potentially. The information needs to be passively available, just like in the screen where you see anything which fits, in accessibility the accessible software might also demand immediate access to the information and navigate around it even without any input to the software. So it might want to read even invisible stuff. We could add callbacks and change the creation to on demand, but I wonder if it is worth to complicate the code (which already was quite problematic to get working on Carbon). Maybe we should simply add a property to turn off accessibility for objects like the code explorer, which creates huge amounts of items and wants to optimize for speed. And add an option to turn accessibility for it on for those that need. -- Felipe Monteiro de Carvalho -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

so which one is correct?
IMO Integer is a compiler built-in type, and thus it doesn't have a reference
to the current declaration. The same for Char and string types :-(
it was but one of several i assumed would be documented by default :(
I already mentioned that flaw, and suggested conditional declarations:
{$IFDEF fpdocsystem}
type
integer = LongInt;
cardinal = LongWord;
...
char = WideChar;
string = UnicodeString;
...
{$ENDIF}
In my own docs I added topics for all basic types. Common to all these
workarounds is the missing correspondence to the effective declarations, so that
a signed 16-bits integer entry will survive ad nauseam, if nobody happens to
find and update such entries. E.g. AnsiChar is described as an alias for Char,
which in fact should read the opposite way, and nowadays even Char=WideChar.
yeah, i've run into some problems in a tool that i'm trying to complete with
some of this type of stuff... i actually had to set sw_integer for some types
that should have worked with integer... i /just/ found out what sw_integer is
(objects unit - alias for longint)... but that brings me to another problem i
think i may have run into but i gotta find the posts that pointed me in that
direction and it has been a week or two :?
I found no time yet to create an overview of all the basic (built-in) types,
which would allow to update all these types in one single place, whenever the
declarations are changed in the compiler.
ahhh... that might be a bit of a mess?
why does basic stuff, eg: 'write' and 'writeln' not have any help at all?
Thanks, I didn't realize that yet. It's for the same reason: these are compiler
magics, for which FPDoc doesn't find a declaration in the source code, and
consequently ignores all such element, even if they exist in the XML files.
See above for possible workarounds.
ahh... i found them quite quickly by hitting all routines and 'keywords' that
/i/ didn't write in my project ;) for example, i know that i have not written
any help (yet) for my TLEEpoch procedures and functions so testing docs by
trying to find them won't work but a lot of other code i didn't write as it is
mostly library code which i would expect to have been documented after all this
time and these discussions...
where is the help for items like 'PadRight', 'AddChar', 'PadLeft', 'AddCharR'
and similar??
I just can't find in which units these are declared. The FCL is only documented
to a small percentage, perhaps these functions reside in such undocumented
units?
these are in strutils... i found them by using uncle google which is quite the
laugh because all of this is about *offline* help so these things can be found
when one is unable to be online :lol:
remember, we are coming at this as a pure newbie with some coding knowledge,
no books, and an extremely simple background in programing... yes, much of the
basic stuff really does need to be specified ;)
Please create an according FPC bug report, if none exists yet, and hope that
somebody will update the documentation.
i may figure out where and how to start but i've already got too much going on

Both are correct. The default size of Integer in FPC is 2 Bytes (16 Bit). Only
if you use mode Delphi or ObjFPC the size is 4 Bytes (32 Bit) and there it is
indeed introduced by the ObjPas unit which is automatically included by the
compiler in these modes.
yes, so i've found out... my project is (now) {$mode objfpc}{$H+} whereas
before it was in turbo pascal mode when i started it in text mode FPC... i had
to switch to using lazarus because i wanted the HasOption stuff for easier
command line processing which seems to only be available in a TApplication...
this is something else i tentatively plan to write about and ask why HasOption
and related functions are not available for all and a TApplication then uses
them... i made some rather large changes to my project which should be quite
simple and small :?
why are both being shown to me?
why does basic stuff, eg: 'write' and 'writeln' not have any help at all?
I don't know. At least the two ARE documented.
yes, they are documented but i guess that lhelp shows all entries when it cannot
determine which one is specific to the code in question... there were a few
others that showed me 5 or 6 options to choose from to see their definitions...
another thing with that is that i then had to close lhelp and hit F1 again to go
back to the choice dialog to choose another reference to read and see if it was
what i was after...
where is the help for items like 'PadRight', 'AddChar', 'PadLeft',
'AddCharR' and similar??
If you have the unit StrUtils included then it should work (it should be
rtl.chm).
i do and they, themselves, work but the latest stable documentation pointed to
by the default F1 help page - the wiki takes you to sourceforge where i chose
the before named file to download...
earlier i followed another path from the wiki (i believe dodi pointed me to it)
and come up with a whole different set of documentation archives that appear to
also be for the latest stable version :?

For the writeln() keyword as you put it, DocView took me to RTL -
Reference for unit 'System' Procedures and Functions Writeln
It seems to be a problem of the IDE or the integration package, because
searching for Writeln in the search tab of lHelp works
interesting... it doesn't make sense (yet) but it is interesting...
(Note: Other identifiers that are not physically present in the system unit
are not shown either, like Boolean. But e.g. PtrInt exists)
@graeme: does docview work with chm files? i haven't looked at it, yet, if if
does, i'm curious if it will find things that lhelp doesn't in the same chm
files when invoked by placing the cursor on a {dang, what terms to use??} word
in the IDE and hitting F1 (or CTRL-F1 for docview as an external app)...

FWIW2: i haven't updated this and my other main dev box to FPC 2.6.0 because, as has happened in the past, i've had to wipe everything and start all over pulling from the SVN and then bootstrapping up from there... it is easy to do lazarus but updating FPC and then trying to make it and then laz always break some how for me :( -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

LCLProc has procedure DebuglnThreadLog which refers to vtUnicodeString
which doesn't compile with FPC 2.4.4.
It should be embedded in IFDEF. Is VER2_6 the right define? Like:
{$ifdef VER2_6}
vtUnicodeString:
s:=AnsiString(UnicodeString(s)+UnicodeString(Args[i].VUnicodeString));
{$endif}
AFAIK 2.6 does not have it.

Once again you are creating unnecessary work for yourself. Michael van Canneyt has already documented all the basic (built-in) types in the FPC Language Reference (the chapter on Types). Can't get more clear than that. the problem, then, must either be in the latest stable chm files i downloaded OR in lhelp... my path was this... 1. Help-Online Help 2. browser loads file:///C:/freepascal/laz/docs/index.html 3. click on Installing CHM help in the IDE - http://wiki.freepascal.org/Installing_Help_in_the_IDE#Installing_CHM_Help_for_The_RTL.2C_FCL_and_LCL_in_the_Lazarus_IDE 4. follow the instructions (as i detailed in my first post) to download the latest stable Lazarus CHM help files from http://sourceforge.net/projects/lazarus/files/Lazarus%20Documentation/ 5. there i chose Lazarus 0.9.30.2 since it has the newest date (2011 Nov 25) http://sourceforge.net/projects/lazarus/files/Lazarus%20Documentation/Lazarus%200.9.30.2/ 6. there i chose fpc-lazarus-doc-chm-0.9.30.2.tar.bz2 because it has the same date AND it is CHM whereas the only other option in there is HTML... 7. i completed the rest of the installation and here we are... i note that martin has added a step 6 to those wiki instructions... it has you confirm that HelpExe is proper and also says to set HelpFilesPath to where the chm files are... but[!!] i _have not_ changed HelpFilesPath from its blank setting and the help /is/ working but not for all terms tested... i'm not sure, at all, what is going on there or why it is working without that field being filled in...
