Regular expressions might match empty ranges, which weren't handled properly, but generally simply omitted. For example, the regular expression "^$" (empty line) never matched because we assumed empty results were not interesting, and actually needed more care in the code. Alike, an expression matching only on its lookahead part, like "a?(?=b)" against "b", would stop further search, although it could even match a non-empty range if "ab" is present later in the input. This last kind of expressions also lead to double-replacement because they first matched "ab" and then "b" alone when re-matching after the "a" replacement. This commit fixes: * searching when the matched range is empty; * step-by-step search when matching an empty range; * double replacement when the pattern re-matches an empty range straight after a replacement; * replacement to and empty string when the matching an empty range. A know issue though is the step-by-step replacement that won't replace an empty match but rather find the next match.
Geany - A fast and lightweight IDE ---------------------------------- About ----- Geany is a small and lightweight integrated development environment. It was developed to provide a small and fast IDE, which has only a few dependencies from other packages. Another goal was to be as independent as possible from a special Desktop Environment like KDE or GNOME. So it is using only the GTK2 toolkit and therefore you need only the GTK2 runtime libraries to run Geany. Features -------- The basic features of Geany are: - syntax highlighting - code completion - auto completion of often used constructs like if, for and while - auto completion of XML and HTML tags - call tips - folding - many supported filetypes like C, Java, PHP, HTML, Python, Perl, Pascal - symbol lists - embedded terminal emulation Requirements ------------ For compiling Geany yourself, you will need the GTK (>= 2.16.0) libraries and header files. You will also need its dependency libraries and header files, such as Pango, Glib and ATK. All these files are available at http://www.gtk.org. Furthermore you need, of course, a C compiler and the Make tool; a C++ compiler is also needed for the required Scintilla library included. The GNU versions of these tools are recommended. Installation ------------ Installing Geany is done by the following three commands: $ ./configure $ make (as root) % make install For more configuration details run $ ./configure --help If there are any errors during compilation, check your build environment and try to find the error, otherwise contact the mailing list or one of the authors. See the manual for details (geany.txt/geany.html). Usage ----- To run Geany just type $ geany on a console or use the applications menu from your desktop environment. There a few command line options. See the manual page of Geany or run $ geany --help for details. Or look into the documention in the doc/ directory. The most important option probably is -c or --config, where you can specify an alternate configuration directory. Windows ------- Geany runs also under Windows. To download the binary with all necessary files, visit Geany's homepage. But you should know, that the Windows version is not yet well tested and there are some features missing: - build support (implemented but might be still buggy) - embedded terminal emulation (VTE) - Windows 9x users: in order to run Geany on Windows 95, 98 or ME you need to install the file SHFolder.dll either in the Geany installation directory or in your Windows directory.
