BUILD INSTRUCTIONS ARE OUT OF DATE

[drposts]

I am unable to build the latest commit.

The following refers to the build instructions in SciTE4AutoHotkey/README.MD and in
SciTE4AutoHotkey/scipatches/README.MD

1. I suspect the prerquisites to build SciTE4AutoHotkey are not complete.
   The instructions state that msys2 with clang64-toolchain plus git, and mercurial are prerequisites.
   Other packages including base-devel, make, patch, and mingw-w64-i686-toolchain may be required.

2. The scintilla and scite cloning instructions are cloning the current version (532) instead of the reported build version 5.2.2.

3. The patch files cannot be accessed by the current instructions. It appears that the files in the scipatch folder need to be
   copied from SciTE4AutoHotkey/scipatches to the primary folder

4. Scintilla.dll and lexilla.dll appear to build correctly. The SciTE.exe build locks up at the make CLANG=1 command.
   HERE IS THE MSYS2 CLANG SHELL INPUT AND OUTPUT:
   =====================================================
   CLANG64 /d/_GITMSYS2/SCITE4AHK
   $ cd scite/win32 && make CLANG=1 -d && cd ../bin && strip *.exe *.dll && cd ../..

HERE ARE THE LASTEST AND ALMOST WORKING SET OF BUILD INSTRUCTIONS:

OBTAIN MSYS2
Obtain msys2 from https://msys2.org/ and install it using all default recommendations. This will install MSYS2 in "C:\msys64".

NOTES:
- FOR SUBSEQUENT LINES BEGINNING WITH "○", THE TEXT AFTER THE "○" SHOULD BE ENTERED ON THE SHELL COMMAND LINE.
- Use cut and pasted to avoid typos

*Open the "MSYS2 MSYS" shell from the Start menu:

UPDATE MSYS2:
○ pacman -Syuu
NOTE: The above line will update msys2. Repeat this step until there are no more packages to update.
(ref: https://www.msys2.org/wiki/MSYS2-installation/)
○ pacman -S --needed bash pacman pacman-mirrors msys2-runtime
- Answer "y" to all requests.
*Exit and restart MSYS2
○ pacman -Su
* Repeat the above step until there is nothing to update and nothing to do.
* Restart the MSYS2 MSYS shell and repeat the above command until there is nothing to update and nothing to do.

PREPARE MSYS2 development environment (NOTE THERE IS SOMETHING MISSING HERE)
○ pacman -S base-devel git make mercurial patch
○ pacman -S mingw-w64-i686-toolchain mingw-w64-clang-x86_64-toolchain
- Consider pacman -S cvs wget p7zip (ref: https://wiki.qt.io/MSYS2)

*Close "MSYS2 MSYS" shell.

NOTE: The "MSYS2 CLANG64" shell will be used for all of the remaining command lines.

*Open the MSYS2 CLANG64 shell

GETTING THE SOURCE AND PATCHING IT:
Make a repository directory to work in
- Make the repository directory. FORMAT: mkdir //
_--- (I used "○ mkdir /d/GITMSYS2/SCITE4AHK")
- Change to the repository directory. FORMAT: cd //
_--- (I used "○ cd /d/GITMSYS2/SCITE4AHK")
Clone data to the repository directory
○ git clone --recursive https://github.com/fincs/SciTE4AutoHotkey
○ hg clone http://hg.code.sf.net/p/scintilla/code -u rel-5-2-2 scintilla (MODIFIED)
○ git clone https://github.com/ScintillaOrg/lexilla -b rel-5-1-6 lexilla
○ hg clone http://hg.code.sf.net/p/scintilla/scite -u rel-5-2-2 scite (MODIFIED)
Copy patch data to base directory (THIS STEP WAS NOT IN THE README.MD BUT SEEMED THE MOST LOGICAL)
○ cp SciTE4AutoHotkey/scipatches/. ./
Patch the code
○ cd scintilla && hg update rel-5-2-2 && cd ..
○ cd lexilla && git apply ../lexilla.diff && cd ..
○ cd scite && hg update rel-5-2-2 && hg import --no-commit ../scite.diff && cd ..
Copy the icon
○ cp SciTE4AutoHotkey.ico scite/win32/

**BUILDING THE COMPONENTS:**
	○ cd scintilla/win32 && make CLANG=1 && cd ../..
	○ cd lexilla/src && make CLANG=1 && cd ../..
	○ cd scite/win32 && make CLANG=1 -d && cd ../bin && strip *.exe *.dll && cd ../..   

(THE ABOVE LINE IS WHERE THE BUILD CURRENTLY FAILS)

**MOVING THE COMPONENTS:**  _(THIS IS ALL NEW)_
	**Rename old files to be replaced in working directory:**
	○ cd "/c/Program Files/AutoHotkey/SciTE"
	○ rename Scintilla.dll Scintilla.dll.old
	○ rename lexilla.dll lexilla.dll.old
	○ rename SciTE.exe SciTE.exe.old

	**Copy new files to working directory**
	**NOTE:** "/d/_GITMSYS2/SCITE4AHK" below is my repository.  Yours might be different.  
                       _(See: Make a repository ... above)_
	○ cp /d/_GITMSYS2/SCITE4AHK/scintilla/bin/Scintilla.dll ./
	○ cp /d/_GITMSYS2/SCITE4AHK/lexilla/bin/lexilla.dll ./
	○ cp /d/_GITMSYS2/SCITE4AHK/scite/bin/SciTE.exe ./

	**Finally copy the latest AutoHotkey Unicode 32-bit binary into the same folder as InternalAHK.exe.**
	○ rename InternalAHK.exe InternalAHK.exe.old
	○ cp "/c/Program Files/AutoHotkey/AutoHotkeyU32.exe" ./

*Close "MSYS2 CLANG64" shell and run the updated SciTE4AutoHotkey. You can revert to the old version by deleting the transferred files and renaming the .old files.
