Copy Snippet for VS Code

Copy Snippet is a Visual Studio Code extension for copying text with line numbers and the file path to the clipboard. Multi-region selections are delimited with ellipses.

Created to help with writing vulnerability/bug reports where it's useful to include focused snippets of source code to explain an issue.

Installation

Install through the Visual Studio Code Marketplace: https://marketplace.visualstudio.com/items?itemName=chrisjdavies.copy-snippet

Example

See the following screenshot of the before/after:

The verbatim text copied to the clipboard in this case was:

     [kern/kern_exec.c]
      220 int
      221 sys_execve(struct thread *td, struct execve_args *uap)
      222 {
      ...
      230 	error = exec_copyin_args(&args, uap->fname, UIO_USERSPACE,
      231 	    uap->argv, uap->envv);
      ...
      236 	return (error);
      237 }

Notice that:

1. Spaces are used to indent the selection.
2. Ellipses delimit separate regions.

The default indentation included by Copy Snippet is designed to be handy for numbering lines:

     [kern/kern_exec.c]
      220 int
      221 sys_execve(struct thread *td, struct execve_args *uap)
      222 {
      ...
[1]   230 	error = exec_copyin_args(&args, uap->fname, UIO_USERSPACE,
      231 	    uap->argv, uap->envv);
      ...
      236 	return (error);
      237 }

This helps when making references to different parts of the code [1] in a vulnerability/bug report.
