Bash using awk undesirable output

I'm trying to write a script that Highlights TODO comments in a directory or file. The issue that I keep running into is that the I'm trying to have the following output format

TODO: Here is what i need to do -> example-file.txt:linenumber

The parser won't grab the comment because the ':' after the TODO.

#!/bin/bash 
echo "TODO highlighter..." 
grep -Hnr --color 'TODO' $* |  awk -F: '{print $'${@:3}'" -> "$1 ":" $2}'

here is the file ive been using to test (todo-example.java):

//TODO: Bobo region Description
//todo this is good but needs new name
//TODO- John fix

and this is the output:

//output 
todo-example.java:4://TODO: Bobo region Descriptiontodo-example.java:4
todo-example.java:29:   //TODO- John fix todo-example.java:29

//desired output 
//TODO: Bobo region Description -> todo-example.java:4
//TODO- John fix -> todo-example.java:29

I have tried changing the arguments but i cant seem to get the desired results of $3 to $N. Thanks.

you just need the following line in your script:

awk '/TODO/ { print FILENAME": "NR" -> "$0 }' "$@"

to highlight TODO, you can trivially reuse your grep command:

awk '/TODO/ { print FILENAME": "NR" -> "$0 }' "$@" | grep --color 'TODO'
