27. I thought I could create 2 days But I couldn’t
28. I couldn’t create 2days Change specification 1. Coding shell script shell script -> Golang Maybe, can not maintenance 2. source command is not work with Go 3. stdout is caught source command
29. source command is not work with Go // golang // not work exec.Command("source", “something.sh").Run() // not work exec.Command("bash", "-c", "source", "something.sh").Run() 1SPDFTT

30. source command is not work with Go $ shway init shway() { case "$1" in init | load) source <( /usr/local/bin/shway $@ ) || /usr/local/bin/shway $@ ;; set | update) /usr/local/bin/shway $@ && source <( /usr/local/bin/shway load $2 ) || /usr/local/bin/shway $@ ;; *) /usr/local/bin/shway $@ ;; esac } _shway() { IFS=' ' read -A reply <<< "help set update load list init" } compctl -K _shway shway source /Users/usk/.shway/default/.alias source /Users/usk/.shway/default/.completions source /Users/usk/.shway/default/.functions source /Users/usk/.shway/default/.golang source /Users/usk/.shway/default/.history #.zshrc source <(shway init)
31. refer. antibody $ antibody init #!/usr/bin/env zsh antibody() { case "$1" in bundle) source <( /usr/local/bin/antibody $@ ) || /usr/local/bin/antibody $@ ;; *) /usr/local/bin/antibody $@ ;; esac } _antibody() { IFS=' ' read -A reply <<< "help bundle update home purge list init" } compctl -K _antibody antibody #.zshrc source <(antibody init) https://getantibody.github.io/
32. stdout is caught source command $ shway init shway() { case "$1" in init | load) source <( /usr/local/bin/shway $@ ) || /usr/local/bin/shway $@ ;; set | update) /usr/local/bin/shway $@ && source <( /usr/local/bin/shway load $2 ) || /usr/local/bin/ shway $@ ;; *) /usr/local/bin/shway $@ ;; esac } _shway() { IFS=' ' read -A reply <<< "help set update load list init" } compctl -K _shway shway source /Users/usk/.shway/default/.alias source /Users/usk/.shway/default/.completions source /Users/usk/.shway/default/.functions source /Users/usk/.shway/default/.golang source /Users/usk/.shway/default/.history update dot files and brews and install brews source dot files
33. stdout is caught source command // Exit finishs requests func Exit(err error, codes ...int) { log.SetOutput(os.Stderr) log.SetPrefix("shway: ") log.SetFlags(0) var code int if len(codes) > 0 { code = codes[0] } else { code = 1 } log.Print(err.Error()) os.Exit(code) }
