A simple Ruby command line utility that converts files from camelCase to snake_case and vice-versa.
To install:
$ gem install code_caser
$ code_caser
Commands:
code_caser help [COMMAND] # Describe available commands or one specific command
code_caser to_camel --path=PATH # converts files in PATH from snake_case to camelCase.
code_caser to_snake --path=PATH # converts files in PATH from camelCase to snake_case.
To use, pass in the path to the file or folder:
$ code_caser to_camel --path=/folder/subfolder/example_file.js
Passing a folder will convert all files in that folder (non-recursive):
$ code_caser to_camel --path=/folder/subfolder
code_caser will happily convert files in any directory with the required permissions, so exercise caution when passing in a directory! You will be presented a confirmation dialog before any files are converted.
You may also pass in a globbed directory to convert only files that match a given pattern:
$ code_caser to_camel --path=/folder/subfolder/*.js
If you have a mix of camelCase and snake_case names, you can use the analyze subcommand to determine if converting would potentially cause overlap with any existing names.
$ code_caser analyze to_camel --path=/folder/subfolder/example_file.js --verbose
This can help you avoid introducing bugs that would arise from using names that already exist in your code.
Use the --verbose flag to print any changes made to each file to the terminal.
By default, backup copies of each file converted will be saved to a timestamped backup folder in the --path directory. You can prevent backups from being created by passing in the --no-save flag.
