handcrafted

handcrafted is a simple command-line tool to help you list handcrafted go files (files that aren't generated). It takes a list of files in stdin, and outputs the matching files from the list to stdout.

Usage

Get all non-generated files in the current directory:

ls *.go | handcrafted

Add -generated flag to show generated files instead:

ls *.go | handcrafted -generated

Use with find to do the same recursively:

find . -name "*.go" | handcrafted

Use with git ls-files to list all handcrafted files in the git repo

git ls-files -- *.go | handcrafted

Use with go list to get generated files from an arbitrary package:

filter="{{ range .GoFiles }}{{$.Dir}}/{{.}}
{{ end }}{{ range .TestGoFiles }}{{$.Dir}}/{{.}}
{{ end }}{{ range .XTestGoFiles }}{{$.Dir}}/{{.}}
{{ end }}"

go list -f "$filter" runtime/... | handcrafted -generated

Create script/fmt that runs goimports only on handcrafted files:

#!/bin/sh

set -e

cd "$(git rev-parse --show-toplevel)"

if ! [ -f "bin/handcrafted" ]; then
  GOBIN="$(pwd)/bin" go get github.com/willabides/handcrafted
fi

git ls-files -o -c --exclude-standard -- *.go |
 bin/handcrafted | 
 xargs goimports -w
