Observations on FreePascal and Lazarus Development

After beginning to use Lazarus more and more I there a few things I want to write about. I can't say I have studied its workings well enough, or asked around enough. Perhaps there are solutions to the issues, or there are reasons for their being the way they are, but I feel I must raise them all the same. I am welcome to any corrections or criticisms.

Does new FCL functionality need to depend on 2.5.1 compiler or LCL/IDE features?

The first point I want to raise is the matter of the FCL, the LCL and the Lazarus IDE.

Sysadmin Docs:

07/10/2010 - After some rereading and some observations made in the mailing list, I have made some corrections, with notes, and added some notes to help those new to FreePascal (like myself) and those new to some of the Linux tools.

After some struggles to install Lazarus and FreePascal from source I created some scripts to set them up properly and they are working well. I think I am 90% there, enough to get me focused on programming than installing.

Freeswitch G729 pass through for Linksys Sipura

Submitted by devblog on Sun, 11/04/2010 - 17:40

After a rather long thread on the Freeswitch mailing lists I managed to get G729 passthru working on Freeswitch (svn 17048).

Requirements

mod_g729 should be enabled in modules.conf.xml.

In vars.xml G729 should be added to the codec prefs, or should be the only one if you are sure the provider(s) support G729.

  <X-PRE-PROCESS cmd="set" data="global_codec_prefs=G729,PCMU,PCMA,GSM,[email protected],[email protected],G722"/>

Free Pascal Win32 VersionInfo.pas

Submitted by devblog on Tue, 30/03/2010 - 00:01

I wanted to add some Windows version information into my Lazarus/FreePascal programs and tried these two options, one from Anders Melander , http://melander.dk/articles/versioninfo/ and the other a part of RXLib, a general Component Library developed for Delphi and ported to FreePascal, both of which are wrappers around the Win32 GetFileVersionInfo (and related) API functions.

Changing the font size in Drupal's Administration menu

Something you don't think you need until you see it.

The font size in the Administration Menu is 9pt, too small for my liking (your eyes, you mean - Ed).

To change it edit the file //sites/all/modules/admin_menu/admin_menu.css and change the font size. I prefer 12px.

Line breaks, paragraphs and drupal input filters

Submitted by devblog on Sun, 27/12/2009 - 20:43

One area in Drupal that has always tripped me up is the matter of line breaks, paragraph breaks and formatting.

The culprits here are the Line Break Converter, the HTML Filter and the HTML Corrector.

It is an issue I have always had to work my head around, but I think I am now getting the hang of it.

Wherever the Line Break Converter comes across a line of text ending without a <br /> it adds a <br /> to ensure that when the web browser displays the page, the following text starts on a new line.

Setting up Domain Access on Drupal

Configuring Drupal for different publishing roles can be very time consuming. There are lots of modules to install, settings to configure, permissions and roles to grant, input formats, content types, and the whole bandwagon, and these can be very difficult to setup again when you create a new website.

You have to duplicate your database, delete your content and start again, hoping that you don't forget stuff you need.

Down with Grey on White fonts!!

One of my pet hates on the web is grey on white fonts. They really annoy me, perhaps my eyesight isn't that good. For 600 years since Gutenberg mankind has been fed a healthy diet of black fonts on a white background, and all of a sudden the last twenty years has seen web page designers using grey and other pastel colours on a white background.
