Findr

Bored with finding and replacing files by find . -type f -name "*.rb" | xargs sed -i "" -e "s/${1}/${2}/" ?

findr is optimized tool to find files in directory recursively and replace texts in the files. findr has the following features:

• Replace by ruby regexp : You can replace strings by using regexp in ruby. The behavior of sed sometimes differ depends on your os (expecially GNU and BSD ). Moreover, it's hard to replace strings with some contextby using sed, for example when replace strings with new line.
• Show stats : findr shows searched files and results of replacement 🎉 It will really help your development. (use --no-verbose option to supress stats)

$ gem install findr_null

# Replace 'apple' to 'lemon' in all files in current and children directory
$ findr "apple" "lemon"

# Delete a line with 'require' in all ruby file
$ findr "require(.*?)\\n" "" "**/*.rb"

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
