new(github.com/J-Siu/go-png2ico): PNG → ICO CLI in pure Go#13678
Merged
Conversation
Small CLI that reads one or more PNG files and writes a Windows .ico container with the standard `00 00 01 00` header (icon type). Useful for favicon/branding pipelines that only have PNGs on hand. - Pure Go (CGO=0), no runtime deps - Builds against go.dev ^1.26; linux uses -buildmode=pie to avoid the well-known Go+glibc segfault noted upstream (docker-library/golang#402) - Test 1 asserts `--version` reports the built tag - Test 2 base64-decodes a 1x1 PNG, runs the round-trip, checks the ICO magic bytes Verified locally on darwin/arm64 against upstream v2.0.8: $ go-png2ico --version go-png2ico version v2.0.8 $ printf '%s' 'iVBORw0…' | base64 -d > one.png $ go-png2ico one.png out.ico $ od -An -tx1 -N4 out.ico | tr -d ' \n' 00000100
Updated build script and test commands in package.yml.
