Chris Cammack fd51703ad8 Fix a performance issue for swiching back to folded document. 
Use the _isFolding flag to fix several overlooked edge case hangs.
This pull request fixes additional hangs I found after #4867 when working with deeply-nested fully-folded files. The hangs are easy to reproduce by following these steps:

Download the sample file https://raw.githubusercontent.com/notepad-plus-plus/notepad-plus-plus/master/PowerEditor/src/Parameters.cpp
Open the downloaded file by itself in NPP and fold it using Alt-0
Create a new empty tab and remain focused on it
Perform the six actions below, each of which will produce a hang as NPP tries to change focus back to the first tab. On my machine, each hang lasts about 30 seconds. After control returns, refocus the empty tab again and try the next action.
Use File>>Open to reopen the downloaded file, even though it is already open
Drag and drop the downloaded file onto NPP to reopen it
Double-click the downloaded file to reopen it
Right-click the downloaded file and select Edit with Notepad++ in the context menu
Open the downloaded file from the command line: C:\Program Files (x86)\Notepad++\notepad++.exe" .\Parameters.cpp
Click the red [X] in the upper right corner to close NPP
After applying the patch, none of the hangs should happen any more.

Notepad++ is a free (free as in both "free speech" and "free beer") source code editor and Notepad replacement that supports several programming languages and natural languages. Running in the MS Windows environment, its use is governed by GPL License.

Build Status

Appveyor build status GitHub release

To build Notepad++ from source:

There are two components that need to be built separately:

  • notepad++.exe: (depends on SciLexer.dll)
  • SciLexer.dll : (with nmake)

You can build Notepad++ with or without Boost - The release build of Notepad++ is built with Boost.

Since Notepad++ version 6.0, the build of SciLexer.dll that is distributed uses features from Boost's Boost.Regex library.

You can build SciLexer.dll without Boost, ie. with its default POSIX regular expression support instead of boost's PCRE one. This is useful if you would like to debug Notepad++, but don't have boost.

To build notepad++.exe:

  1. Open PowerEditor\visual.net\notepadPlus.vcxproj
  2. Build Notepad++ like a normal Visual Studio project.

To build SciLexer.dll with boost:

Here are the instructions to build SciLexer.dll (for both 32-bit & 64-bit) for Notepad++:

  1. Download the Boost source code. v1.55 should be used with VS 2013. Then unzip it. In my case, boost_1_55_0 is copied in C:\sources\
  2. Go to scintilla\boostregex\ then run BuildBoost.bat with your boost path. In my case: BuildBoost.bat C:\sources\boost_1_55_0 If you are compiling a 64 bit Scintilla under your VS2013 x64 Native tool command prompt, add -x64 flag. In my case: BuildBoost.bat C:\sources\boost_1_55_0 -x64
  3. Go in scintilla\win32\ then run nmake -f scintilla.mak

To build SciLexer.dll without boost:

This will work with notepad++.exe, however some functionality in Notepad++ will be broken.

To build SciLexer.dll without PCRE support (for both 32-bit & 64-bit):

  1. For 32-bit, open a command prompt for building (a.k.a. the Developer Command Prompt for VS2013)

    • From the IDE, you can do this by right clicking on a file in Solution Explorer, and clicking "Open Command Prompt". This will open up a command prompt with all the proper environment variables.
    • From the Windows Start screen/menu, type Developer Command Prompt for VS2013, and click/select the result.
    • From an already open command prompt, run vcvarsall.bat (e.g. "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat").

    For 64-bit, open VS2013 x64 Native tool command prompt.

  2. Change directory (cd or pushd) to scintilla\win32\

  3. Build SciLexer.dll with one of the following commands:

    • nmake NOBOOST=1 -f scintilla.mak (normal build)
    • nmake NOBOOST=1 DEBUG=1 -f scintilla.mak (debugging build)

  4. Copy SciLexer.dll from scintilla\bin\ to the same directory as notepad++.exe.

    • For the Unicode Release configuration, the output directory (where notepad++.exe is) is PowerEditor\bin\.
    • For the Unicode Debug configuration, the output directory (where notepad++.exe is) is PowerEditor\visual.net\Unicode Debug\.
