Added regex logic to handle errors and warnings displayed on console.

Handles jump-to file, line no, and inline position.
Handles console coloring for errors

The method CWarningAnalyzer::match is called for every line that is printed to NppExec's Console, so it may be too expensive to create the same instance of std_Needle again and again. Let's rather make the std_Needle to be a member variable that is created just once.

Looks somewhat unsafe, no? (I mean, we assume that there is an implicit unsigned char dummy right after unsigned char Blue within the TEffect structure to match the sizeof(COLORREF) and that these members are aligned by exactly 1 byte.). I'd prefer explicit setting of the Effect.Red, Effect.Green and Effect.Blue members.

I changed TEffect so that the three unsigned char variables are in a union with COLORREF variable (rgb). And I changed line 449 to the following:
m_Filter->Effect.rgb = COLOR_CON_TEXTERR;
That allows RGB macro to safely be used to set the colors. It's common programming practice on multiple languages to use RGB for color settings. And it's easy to find RGB color charts online.

We may use lstrcmp to compare the existing last 4 characters of filename with _T(".exe") instead of using a temporary string produced by substr.

Good idea. When I went to make the changed, I realized I could just use lstrcmpi, and removed the previous line that changed it to lowercase.

let's use
match[0].str().compare( 0, 3, _T("...") ) == 0
instead of
match[0].str().substr( 0, 3 ) == L"..."

Done. Although the difference is compiled away.

This else if is not a part of a comment, so let's unindent it (remove the leading spaces) to avoid visual confusion of its scope.
This comment applies to all the other indented else if as well.

I'm still working on DebugAnyThing.NppExec.
Is there a way to select the files that should be included in the pull request?
The only files I intended to include was WarningAnalyzer.cpp, WarningAnalyzer.h, NppExecEngine.cpp, and DlgConsole.cpp.

WarningAnalyzer.cpp and WarningAnalyzer.h are the only ones with the regex code changes.

You may create a separate git branch for each independent change (e.g. one branch for the regex to handle errors, another branch for the NppExec script, etc.).
In your case, when everything is already in your "master" branch, probably the best way to separate different things is to:

cancel this pull request

manually copy your changed files to some temporary folder

reset all your changes in the "master" branch

create a new branch e.g. "feature/regex-warn-analyzer", checkout that new branch and manually copy the related changed files from your temporary folder (created in the step 1 above) to this new branch

create a new pull request against this new branch (it will replace the previously cancelled pull request)

checkout the "master" branch and create a new branch e.g. "feature/nppexec-scripts", checkout that new branch and manually copy the related changed files from your temporary folder to this new branch. Thus you'll have two independent branches with independent changes

when all the changes in the "feature/nppexec-scripts" branch are ready, create a pull request against this branch.

Personally I use a portable version of Notepad++, thus there is no "%APPDATA%\Notepad++\plugins$(TargetName)" on my machine.
Also, there is no "%APPDATA%\Notepad++\plugins$(TargetName)" on a generic build machine where NppExec's sources are built.
Maybe let's customize this command to copy only in case of the folder "%APPDATA%\Notepad++\plugins" exists?

I actually didn't intend to merge NppExec_VC2017.vcxproj change with the master. I pushed it on my fork so I wouldn't loose the change.
I did add the if exist before the copy command, so if you want, you could add it to the master.

Let's enclose the condition in parentheses? Frankly, I needed several attempts to understand how this long construction with && and ? works :)
