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.

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`](https://github.com/notepad-plus-plus/notepad-plus-plus/blob/master/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](https://www.boost.org/users/history/version_1_70_0.html).
 2. Unzip boost. In my case, It's unzipped in `C:\sources\boost_1_70_0`
 3. Build regex of boost. With the version 1.70, launch `bootstrap.bat` under the boost root, `b2.exe` will be generated beside of `bootstrap.bat`. For building boost PCRE lib, go into regex build directory by typing `cd C:\sources\boost_1_70_0\libs\regex\build` then launch `C:\sources\boost_1_70_0\b2.exe toolset=msvc link=static threading=multi runtime-link=static address-model=64 release stage`.
 Note that **address-model=64** is optional if you want to build lib in 64 bits. For 32 bits build, just remove **address-model=64** from the command line.
 4. Copy generated message from  `C:\sources\boost_1_70_0\bin.v2\libs\regex\build\msvc-14.1\release\address-model-64\link-static\runtime-link-static\threading-multi\libboost_regex-vc141-mt-s-x64-1_70.lib` to `C:\tmp\boostregexLib\x64\`
 5. Go in `scintilla\win32\` then run `nmake BOOSTPATH=your_boost_root_path BOOSTREGEXLIBPATH=your_built_lib_path -f scintilla.mak`. For example `nmake BOOSTPATH=C:\sources\boost_1_70_0\ BOOSTREGEXLIBPATH=C:\tmp\boostregexLib\x64\ -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 VS2017*](https://msdn.microsoft.com/en-us/library/f2ccy3wt.aspx))
    - 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 VS2017`,
      and click/select the result.
    - From an *already open* command prompt, run `vcvarsall.bat`
      (e.g. "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat").

	For 64-bit, open *VS2017 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 -f scintilla.mak`         (normal build)
    - `nmake 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\`.
