How to find Regular Expression

[bpranoto]

In the IDE, I want to find a regular expression.

1. Open the find dialog
2. Check Regular Expression
3. Uncheck Case Sensitive
4. Fill the Text to find: AsFloat *:=
5. Click Find Button

Unfortunately, an Error dialog popped up: TRegExpr exec: empty input string

Did I miss something or i just found a bug?

Environment:
Lazarus 2.0.12
Ubuntu 18.04

Thanks.

Hi JP,

Something like:

Code: Pascal  [Select][+][-]

1. Self.FQupdate.ParamByName('xxx').AsFloat := xxx;
2.  

The problem is not what I want to find, but the IDE find facility. Even when I put a simple text to find like 'a' it will throw the same error message.

Looks like an erratic bug in recent versions up to and including trunk. Works properly in 2.0.6, not sure about intervening versions.

In Windows the same: works in trunk 2.1.0, fails in 2.0.10.

It is a known bug if FPC's regexpr unit. I already posted the fix, try the more recent FPC 3.2 versions.

[bpranoto]

All, thank you.

Glad it is already fix for the next fpc version. Just curious, does it mean TRegExp suffer the same bug?

[AlexTP]

TRegExp is another component, so it does not.
