cargo build --release

The executable will be found in:

target/release

Usage/Examples

./grep_clone pattern path_to_file

if found

Pattern:        "pattern"
Path:           "path_to_file"
# "pattern" found at line [n]:
        "[...]pattern[...]"

For searching multiple patterns use '|' to separate them inside the same argument passed to the function, as in grep:

./grep_clone "pattern1\|pattern2\|..." path_to_file

The output it's slightly different, more grep-y, since the single pattern output could result confusing for multiple outputs:

Pattern:        "pattern"
Path:           "path_to_file"

        "[...]pattern1[...]pattern2[...]"

It automatically ensures if errors occur while executing and reports them in the stdout.

Roadmap

• Make it work for one pattern ✅
• Add colouring of the pattern searched inside the line printed ✅
• Multiple patterns search ✅
• Implementing grep flags ❌
• Adding test cases ❌
