[Bug 941127] [NEW] IDE freezes if parenthesis entered in search field

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Sikuli Version X-1.0rc3 running on Mac OS X Version 10.7.3 - iMac -
Intel Core i5

Steps to reproduce:
1. Open Sikuli-IDE
2. Press Cmd-F
3. Type "example(" into search box

The IDE will freeze, preventing you from typing anything further for
several seconds. Once it unfreezes, entering any text other than
backspacing over the parenthesis mark will result in another temporary
freeze. Error text is included below. The IDE appears to be interpreting
the text in the search field as an erroneous regular expression, which
is nonstandard among OS X GUI applications and unexpected. Even if a
regular expression were intended, the freezing and immediate error make
it extremely difficult to type.

Temporary workaround:
Always use a backslash before searching for any string containing parentheses. E.g., to search for "example(foo)", search instead for "example\(foo\)".
