sed to parse compiler warning message

I am trying to use sed to grab file path, line number, compiler warning number and warning message but I am failing.

grep -E "C6001|C6011|C28197" release-log.txt |
head |
sed -r 's/^([a-zA-Z\\:.]+)\(([0-9]+)\) warning (C[0-9]+): (.+).(.+)$/(\3) \1:\2 \4/g'

For example, given:

C:\WindowsFabric\src\prod\ktl\src\inc\kallocator.h(196): warning C6011: Dereferencing NULL pointer 'Allocator'. : Lines: 189, 196 [C:\WindowsFabric\src\prod\src\Lease\KTransport\user\KTransport.user.vcxproj]

I want:

(C6011) C:\WindowsFabric\src\prod\ktl\src\inc\kallocator.h:196 Dereferencing NULL pointer 'Allocator'
Solution

  • This job is much easier with awk. You may use:

    awk -F ': ' -v OFS='\t' '{sub(/.* /, "", $2); print "(" $2 ")", $1, $3}' release-log.txt

(C6011) C:\WindowsFabric\src\prod\ktl\src\inc\kallocator.h(196) Dereferencing NULL pointer 'Allocator'.
