svgo-sandbox

Script to launch svgo in a bubblewrap sandbox. An executable file for svgo is built using pkg.

Usage

1. Create a svgo package in the vendor directory, as described below.

2. Add an alias to the ./run script in this repository.

3. Use the alias to invoke svgo.

   The current directory at the moment of executing ./run is the only directory writable in the sandbox. If you want to use the -o option in svgo, the path has to be relative to the current directory.

Example

$ alias svgo=~/path/to/svgo-sandbox/run

$ svgo --help
