Re: [Lazarus] A simple event problem in console program

[DougC]

A TNotifyEvent must be a procedure that is a method of a class. You have 
created and tried to use a plain procedure instead.

That sounds good to me!

DougC: I rebuilt the Windows setup program it now says "Free Pascal 3.0 with 
Lazarus" and in small text below "December 2015 Release". I hope that clears up 
any confusion. In the future I'll keep the build date (month and year) in the 
description.

Re: [Lazarus] FPC Pestering Peacock (3.0.0) release

[DougC]

Download the windows installer and run it. The very first window says "Welcome 
to the Free Pascal 3.0 with Lazarus Setup Wizard" then "This will install Free 
Pascal 3.0 with Lazarus version 3.0 on your computer." This is confusing!

The setup name is now "Free Pascal 3.0 with Lazarus" as defined on Windows at 
least by the setup script.



https://github.com/sysrpl/Codebot.Setup/blob/master/windows/setup.iss



Sometimes Inno Setup mangled the name (which you can edit during install) based 
on some previous install information it keeps around. Regardless of the name, I 
now use the Free Pascal fixes 3.0 branch and Lazarus trunk branch when building 
setups for all platforms. All setups (Windows, Linux, Mac) were updated this 
past weekend and have gone through several rounds of testing to ensure 
everything works as intended.

Re: [Lazarus] FPC Pestering Peacock (3.0.0) release

[DougC]

Why does this installer say it is installing FPC 3.0 and Lazarus 3.0? Has 
Lazarus changed their version numbering? At best I would expect a Lazarus 1.5 
at this point.

wkitty, I just updated the installers at:



http://www.getlazarus.org/setup/



It is built from FPC 3.0 now. It installs to your home folder without needing 
any special rights to install.

Linux/Mac users can change the install folder by changing the $BASE variable at 
the top of the script.

Windows users can just pick a folder in the installer program. 

Lazarus and FPC configurations are read from their own directories and wont 
interfere with other existing installations.

Re: [Lazarus] Encryption compatible with .net

[DougC]

So why is vector in your code? Including irrelevant parts just makes it harder 
for others to help you.



Rewrite your Pascal code to use the same variables as the VB code!

Re: [Lazarus] Encryption compatible with .net

[DougC]

After quick look I noticed that



var

  Vector : array of Byte;



  SetLength(Vector, 8);

  Vector[0] := 1;

  Vector[1] := 2;

  Vector[2] := 3;

  Vector[3] := 4;

  Vector[4] := 5;

  Vector[5] := 6;

  Vector[6] := 7;

  Vector[7] := 8;



does not match



  Dim vector As String = "12345678"



Should be something like

  Vector[0] := '1';

  Vector[1] := '2';

  Vector[2] := '3';

  Vector[3] := '4';

  Vector[4] := '5';

  Vector[5] := '6';

  Vector[6] := '7';

  Vector[7] := '8';



I didn't look at the rest.

Re: [Lazarus] Working on big units

[DougC]

I think you have taken the advice you read somewhere too seriously. You have 
taken it to an extreme that invalidates it.



Having a small number of units is not in any way disadvantageous in terms of 
efficiency from the system's viewpoint. Remember that the unit structure was 
invented to solve the very problems you are experiencing!



You do not have to split your unit based on the classes it now contains. You 
can use other rationale for the split. I have a set of units named



DateSupport

LogSupport

FileSupport

CodeListSupport

SortSupport



Makes it easy to see where the items I want to find are.

Re: [Lazarus] Working on big units

[DougC]

The best way to deal with big units is to avoid them completely.



Can you explain why you are using such a big unit if it is causing you these 
problems?

I Just work on one of my units with about 10,000 line of code that have 7 class

sometimes I get lost that where am I. Just want to ask you how you work with 
big units? how you move,browse and edit?

Hi All,

I was wondering what people thought about using a Google Doc as a help file?



It looks like you can have a contents, use anchors and obviously have pictures.



Any thoughts?





Are you talking about a help file for your app or for Lazarus, itself?



If for Lazarus, what's the problem you are solving by suggesting this? Is the 
existing wiki so bad?



It is a really bad idea to tie your documentation to a single vendor.

I have almost finishing writing a unit - which I will commit to FPC very 
soon - that takes a *sample* json file and creates an object from it. 
The object does not depend on anything, and contains code to stream it 
from/to json in the format that was used to create it. 
 
It should make consuming/producing REST services (using JSON, obviously) very 
easy. 
I will integrate it in the jsonviewer application distributed with Lazarus.

[Lazarus] Recommended install methods

[DougC]

Graeme just posted this to the fpc list as a recommended way to install fpc:
 
Remove all copies of FPC, no matter the 
versions. Remove all copies of the fpc.cfg too. Look in /usr/local/etc 
and $HOME. 

Then download the official FPC release install: 

http://sourceforge.net/projects/freepascal/files/FreeBSD/2.6.4/ 

Untar the file to a temp directory and run the install script. Install 
to your own home directory location - that way you don't need root 
privileges. For example: 

/home/freds/devel/fpc-2.6.4/ 

Using version numbers in the install location also means that you can 
install other versions of FPC concurrently. You can then tweak the 
~/.fpc.cfg to use $fpcversion macros instead of hard-coded version 
numbers. That way all FPC install share the same ~/.fpc.cfg file. 

If you need the FPC source code, download that from SF.net too, and 
unpack that in /home/freds/devel/fpc-2.6.4/src/ 

I then amend my PATH environment variable to include the stable FPC 
"bin" directory, so I can use FPC from anywhere in my system, simply by 
typing 'fpc '. Other FPC versions can be used by 
specifying the full path to the fpc binary. 

I've used this setup for years - first with Linux, then the last 3 years 
with FreeBSD. This has always worked without fail. I NEVER use any 
package management version of FPC, and neither to I use FreeBSD ports to 
install FPC. The official FPC release installer is all you need. 


Regards, 
- Graeme - 

I like this approach. Is there a similar (not any more complex) recommended way 
to handle Lazarus installs that allows for multiple versions to be 
simultaneously installed and used interchangeably?
