I guess I will have to get around to learning how to build fpc and
lazarus on Windows then...


Install fpc from the fpc installer. Or keep the fpc as installed by the 
lazarus installer. (If you move the directory, you need to edit fpc.cfg)


Keep a lazarus.exe

Get the lazarus source (svn or otherwise; or patch the existing one).

- Copy the lazarus.exe into the top level of your source folder.
- Optional: create a lazarus.cfg file with the primary conf path 
http://wiki.freepascal.org/Multiple_Lazarus#Using_lazarus.cfg_file
- Run it (make sure all pathes are correct in Tools Options / or run 
with --setup)

- choose menu Tools > build lazarus

Open and build the ide/startlazarus project.

Please check this kind of errors, with 1.8.2 (once released) or the bug 
fix patch applied.

If an incorrect bracket is highlighted with the fix, then please report it.

Note that, brackets in strings or comments, will/should not be matched 
with brackets in code.


   if (a = '(' ) then // (
        a := ')';  // )

should match
- the 2 brackets in code
- AND the 2 brackets inside the 2 strings
- AND the 2 brackets inside the 2 comments

It should also match the correct quotes '.

Bracket matching only ever looks at one kind of brackets.
When matching (), it will totally ignore any [].
So erroneous code like
  if (a[1]] = 2) then
will match the ().
As well as the [] directly around the 1.
And the extra ] will not match anything.

OK, I see
There are strange highlighting going on, example:
Parms.Add(IntToStr(Rev));
Here if I put the cursor left of the ; I get hightlight properly.
But any place before or after any other ( or ) no highlight!

In another code line if I do the same and put the cursorat the end );
between the last chars, then the highlight comes on and boxes the last

Well, the other highlightings seem to work at least.

Martin, thanks for your detailed description! It made it possible for
me to at least partially solve the problem!
which part (about begin/end) is NOT solved? (Or does "partly" refer to 
brackets?)




brackets are already answered in the other mails.

But the links in these replies go to a webpage that says a bit down:

"Bracket Highlight

If the cursor is behind or in front of a bracket, highlight matching
bracket"

And that is all. No description on *how* to actually activate this
function, which was clearly not working in my Lazarus...

Same options dialog/page as above "Markup and Matches"

There is a dropdown "Bracket highlight" (below the 1st divider / unamed 
divider)
 with options such as "on both sides", "Left of cursor",  "no 
highlight"


I am not sure, it may require that the text has some highlighter active 
(but pascal sources always have this).

If you load plain text, then it may not work on that file...

It matches (), {}, [], and single quotes. It toggles between bold and 
not bold, and applies a frame (at least for me, I may have changed settings)
But again in color options you can change what highlight to apply: 
Editor > Display > Colors:

   Entry "Bracket Highlights" (1st in section "Text").


Furthermore the webpage directs me to the "Automatic feature" page of
the editor option, which in fact does not exist in my Lazarus.
Under Editor there are 8 subpages, none named "Automatic feature". If
one expands the Display node there are Colors, Markup and Matches,
User defined markup. So the wiki page is misleading.

The wiki is indeed outdated. (If anyone has time...)
"Automatic ..." was probably the name of a sub page in an older Lazarus 
version.



begin/end is not on the wiki (yet), but it is in the Options dialog
under > Editor > Display > Markup and Matches

It is called "Word Brackets on caret"

There is a listbox with: "Procedure","Begin/end", "repeat" .
you can select each entry and check "Markup (on caret), to get the highlight

In my case these are all checked except for the last 4 boxes.
Additionally the checkbox to the right "Markup (on  caret)" is checked
as is the top "Word Brackets on caret" and yet I did not see anything
in the IDE...
Do I have to use some kind of hot key to make it display?
Well, it seems to be a mis-match in the default settings where the
feature is enabled by default but the colors are set by default to
completely hide the highlight


Which color profile are you using? (Default, Delphi, Ocean)
In the Default it should have a red frame (for begin/end pairs)

You can always check the default by deleting (BACK UP !) your 
editor_options.xml

This is in the primary config path (View Menu > Ide Internals > About IDE


After a lot of fiddling I managed to get the following working:

begin-end:  A red box pink background via "Word-brackets" color
[ ]: basically the same, but via "Brackets highlights" color
if-then-else: same via "Word-brackets" color

Not working:
( ): Controlled by what?

Should be the same as ()

Just remember, I think there is a bug in 1.8 (already fixed for the not 
yet released 1.8.2)


brackets only work if they are surrounded by spaces (or maybe it was NOT 
surrounded...)

And that is all. No description on *how* to actually activate this

Also the definition of a "bracket" is a bit muddy. Does it refer to
square parenthesis [ ] or normal ( ) or begin end or all of these?

the editor option, which in fact does not exist in my Lazarus.
Under Editor there are 8 subpages, none named "Automatic feature". If

"Procedure"  is just Procedure ...end
