Capturing Visual Stadio Command Line Compilier (CL.EXE) Output With Regular Expressions - json

Question

I've been trying to set up VS command line compiler to use in VS code IDE. I have read the examples and can use GCC with no problem but need to use VS compiler now too.
I have tried a single line problem matcher and I multiple one. Yet VC code seems to capture nothing.
Here is an example of output with error from the compiler:
Microsoft (R) C/C++ Optimizing Compiler Version 18.00.40629 for x86
Copyright (C) Microsoft Corporation. All rights reserved.
helloWorld.c
..\Code\helloWorld.c(7) : error C2143: syntax error : missing ';' before '}'
Using the regExpr Expression:
(.*\n){2,3}\S+(\d+)\W+:\s(\bwarning|error\b\s\w+):\s(\w+\s\w+)\s+:\s(.*)$
It captures all the info I need (checked my work here: https://regex101.com/)
but when I put it in a Tasks.json file for VS code it doesn't work.
{
"version": "0.1.0",
"command": "Build",
"args": [
"${fileBasename}"
],
"isShellCommand": true,
"tasks": [
{
"taskName": "Build",
// Make this the default build command.
"isBuildCommand": true,
// Show the output window only if unrecognized errors occur.
"showOutput": "always",
// No args
"args": [
"all"
],
// Use the standard less compilation problem matcher.
"problemMatcher": {
"owner": "cpp",
"fileLocation": [
"relative",
"${workspaceRoot}"
],
"pattern": {
"regexp": "(.*\n){2,3}\\S+(\\d+)\\W+:\\s(\bwarning|error\b\\s\\w+):\\s(\\w+\\s\\w+)\\s+:\\s(.*)$",
"file": 1,
"line": 2,
"severity": 3,
"code": 4,
"message": 5
}
}
}
]
}
Anyone know how to setup VS Code IDE to use VS command line compiler? Any help would be greatly appreciated

Answer 1

The first two lines in your output can be avoided by adding /nologo flag to the compiler. So your tasks.json should be:
"tasks": [
{
"taskName": "Build",
"isBuildCommand": true,
"showOutput": "always",
"args": [
"all"
],
"problemMatcher": {
"owner": "cpp",
"severity": "info", // treat note as info
"fileLocation": "absolute",
"pattern": {
"regexp": "^(.*)\\((\\d+)\\):\\s+(warning|error|note)\\s*(\\w+)?:\\s+(.*)$",
"file": 1,
"location": 2,
"severity": 3,
"code": 4,
"message": 5
}
}
}
]
