I just received my copy of Linux Journal:
Issue 185 with the 5-page Lazarus article by Mattias Gaertner.
After many years, finally Lazarus in Linux Journal,

Good job, Mattias !

Hi,
Does the Lazarus IDE use multi-threading for anything? Will it take
advantage of a Quad Core processor?
Examples where I think it could be used (if not already)
- background parsing of units
- fpdoc lookups
- compile project in separate thread (currently the IDE is

The IDE itself is single threaded.

Threads require less overhead than forking or spawning a new process

Before submitting a bug, I just want to check my understanding is correct.
crDefault (at least on Windows) is supposed to show the Systems default
for wherever the cursor is.
That means over an Edit field this is a IBeam cursor and not an arrow.

IMO crDefault means that the actual shape of the cursor is not
determined by the control under the cursor, but instead the control's
parent cursor is used (recursively). When

Interesting, I'll take a peak at that.
The disadvantage of using the same process is that the coupling is much
tighter: No easy switching between compiler versions, and crashing the
compiler
Can somebody that is more familiar with the internals of the Lazarus IDE
tell me, would it be hard to implement the IDE with FPC built in, so that
compiling can be done in a separate thread instead of separate process? I'll
do the work of course - if it's not a major job. ;-)
The most hardest

Anyone using LazReport in production environment? I'd like to start doing more

for may types of projects that I do.

Probably simple. The compiler is started by the compile function in
