Bundle Report

Bundle size has no change ✅

[abitrolly]

There is another query I needed - a breakdown of sizes by function for comparison.

gsa /usr/bin/runc -f json | jq -r '.packages."github.com/urfave/cli".files[] |
  "\(.file_path)", (.functions[] | "    \(."type") \(.receiver).\(.name) \t\t\(.code_size)")

But jq doesn't have a function for human readable output and columns are not aligned, and there is extra "." when .receiver is empty.

Thanks for the contribution, but this seems too limited to a specific scenario, and the Bash syntax doesn't look quite right.

[abitrolly]

@Zxilly so what syntax do you propose?
