This small utility is designed to rename all files in a folder according to a specified naming convention (camelCase, snake_case, kebab-case, etc.).

It currently supports the following naming conventions:

• camelCase
• kebab-case
• lower case
• PascalCase
• SCREAMING_SNAKE_CASE
• Sentence case
• snake_case
• Title Case
• Train-Case

1. Download the latest binary executable release supported by your OS.

   For most Linux distributions, download stdrename-x86_64-unknown-linux-gnu.

   For Windows, download stdrename.exe.

   No macOS binary is available yet, but stdrename can still be installed using Cargo.

2. Add it to your PATH.

   On Linux and MacOS, this is achieved by executing the following command in your terminal after downloading the file.

   chmod +x ~/Downloads/stdrename && sudo mv ~/Downloads/stdrename /usr/local/bin

   On Windows, you can move the file to a new folder such as "C:\Users\YourName\bin" and then add the folder to your PATH using the instructions here.

If you have cargo installed you can install stdrename with:

cargo install stdrename

The executable file can then be found in $HOME/.cargo/bin/stdrename.

On Linux and MacOS to make sure $HOME/.cargo/bin is in your $PATH add the following line at the end of .bashrc (in your home directory):

export PATH="$HOME/.cargo/bin:$PATH"

You must specify the naming convention you want to use with the appropriate flag. For example, this will rename all files in the current directory using the kebab-case naming convention.

stdrename -k

Here is the full list of naming convention flags that can be used:

You can also specify a different folder to parse with a second argument e.g.:

stdrename -k ~/Pictures

To rename recursively, use the flag -r or --recursive e.g.:

stdrename -kr ~/Pictures

To rename directories as well, use the flag -D or --dir e.g.:

stdrename -kD ~/Pictures

By default, patterns in .gitignore files, global gitignore files and git exclude files will be ignored as well if the directory is a git repository.

You may also add a .ignore file with patterns to ignore in the file's directory and its subdirectories.

This file may use any of the glob patterns that can be used in a .gitignore file. It is functionally the same, just with a different name e.g.:

Adding the following line in a new .ignore file in the same directory as stdrename will ignore all files with the extension .py and all files in the subdirectory ./target/ when renaming.

# ./.ignore
# ignore all files ending with .py
# ignore all files in /target and its subdirectories

*.py
/target

You may even add a second .ignore file in a subdirectory e.g.:

# ./subdir1/.ignore
# match .py files despite previous instructions
# ignore .txt files in this directory and all subdirectories

!*.py
*.txt

All files in that directory and all sub directories will then reinclude .py files and ignore .txt files.

If you'd like to use global ignore patterns specific to stdrename, you can do so by creating an "ignore" (notice this one does not start with a ".") in the following location:

On Windows: %USERPROFILE%\AppData\Local\stdrename\"

On Unix based systems (e.g. MacOS or GNU Linux):

$HOME/.config/stdrename/

This file follows the same pattern matching principles as other .gitignore or .ignore files and has a lower precedence than all other sources of ignore rules.

Text mode allows for either piping through stdin, e.g.:

echo 'Hello World' | stdrename --text -k

or interactive use, e.g.:

stdrename --text -s
reallyCreativeProgramName.js
really_creative_program_name.js
PYTHONISTA_BANANA.py
pythonista_banana.py
This is really just a normal sentence
this_is_really_just_a_normal_sentence

Either way, the program terminates and stops reading as soon as it encounters an empty line.

To suppress the exit message (if piping stdout to another file for example) add the -q or --quiet flag.
