Annoying response to source errors while typing
lazarus / 9-Editor

I don't know when this feature was introduced, but the current trunk
version at least has an annoying error checking feature while typing:

Create a new project in Lazarus. After implementation type

Code: [Select]const
  N = 1   // forget the semicolon!

procedure Dummy(

When you type the opening bracket after "Dummy" the cursor jumps to
the start of line, and there is a unimpressive error message in the
event window. Since I normally don't realize that I am messing up the
entire line this way.

This happens when an error exists somewhere in the source code, in
this case it is the missing semicolon after N=1.

The compiler will tell me later that something is wrong somewhere in
the file. Therefore, I don't like this feature at all. Is there a way
to turn it off?

Probably
Tools > Options > Editor > completion and hints > Auto display
prototypes

This triggers codetools and goes to the error.


[edit]: Fixed

Yes, that did the trick.

But I wonder if there's anybody around who understands that "Auto
display prototypes" means "auto-detect errors while typing". And I
wonder also if this feature should not be off by default.

[EDIT]
Just saw in svn that you already have fixed the sourceeditor.
Impressive! Now the editor is behaving correctly even with
AutoDisplayPrototypes turned on. Thanks!

It was not meant to detect the error (and no longer does).

It opens the hint, with the list of params to a procedure, if you type
"("
That is it shows you the prototype of the procedure.

Many people new to the language (and new to the IDE) benefit from
that. (Many have also asked for other similar things, like completion
dropdown, to always show / And many other IDE do)

Of course experienced users on the other side want less of this
automation. So there is no perfect setting.

While the IDE is highly customizable, it is (due to that) also true,
that many options are hard to find.
But they are hard to find to newcomers, as well as experts. Yet I
guess the experts have more means and experience in how to find those
settings. So I thought to make it newcomer friendly...

I completely agree. And thanks again for the immediate fix (see my
posting above)
