A very naive script that converts any SVGs in the current directory into PNGs using the rsvg-convert tool. Requires installing librsvg (brew install librsvg).

convert-svg-to-png.sh

#!/bin/zsh

# Convert all SVG files in current directory to PNG using librsvg.
for svg_file in *.svg; do
    #  Check that this is in fact an SVG file.
    if [[ ! -f "$svg_file" ]]; then
        echo "$svg_file is not an SVG file"
        continue
    fi
    
    # Get filename without extension.
    base_name="${svg_file:r}"
    
    # Run rsvg-convert command.
    echo "Converting: $svg_file -> ${base_name}.png"
    rsvg-convert --width 1024 --keep-aspect-ratio "$svg_file" --output "${base_name}.png"
    
    # Check if conversion was successful.
    if [[ $? -eq 0 ]]; then
        echo "✓ Successfully converted $svg_file"
    else
        echo "✗ Failed to convert $svg_file"
    fi
done

echo "Conversion complete!"

    if [[ ! -f "$svg_file" ]]; then
        echo "No SVG files found in current directory"
        break
    fi

Interesting that Claude thinks that the non-existence of a particular file means that no SVG files were found. You kind of don't really need this test at all, since every output of the glob expression can safely be assumed to be a file. (I can't think of a scenario where the match of a glob expression isn't as file or symlink or link. The only case I can think of would be if you had a sub-directory named subdirectory.svg, in which case the edge case error message should be "Not a file," not "No svg files".

This was interesting to look at. It's really interesting to see the solution patterns that Claude (et al) predict.

The only case I can think of would be if you had a sub-directory named subdirectory.svg, in which case the edge case error message should be "Not a file," not "No svg files".

@apotek Good point. I updated the script to echo a more useful message and also to continue instead of break in such a case.

Thanks for the feedback!
