comment-strip

Strip comments away.
Delete comments out of text files.

Comments are helpful in configuration files, source code, shell scripts and any other text based files. But sometimes they only distract from the actual content. So with this tool you can strip away the comments of the most common formats.

Currently supported comment styles:

• Shell style
• XML style (CDATA tag is not escaped)
• C style

I started this project to enhance my practical knowledge of the rust programming language. I could not find an easy applicable solution to the problem with detecting comments, except for some sed magic, so I decided to give it a try. If you like the tool and would like to contribute or simply leave a note, feel free to open an issue.

Installing / Compiling

To install comment-strip you can use cargo. Simply run cargo install comment-strip to install the latest version.

To compile comment-strip yourself, you need somewhat recent version of rust. If you are using cargo, it's easy to get an executable.

1. git clone git@github.com:XOSplicer/comment-strip.git
2. cd comment-strip
3. cargo build --release
4. cargo test (optional)
5. ./target/release/strip --help to display usage
