Code Logic

  • save SSH configurations into a SQLite.db in $HOME/.felix.db
  • use spf13/cobra as command framework

felix ginbro Logic

  1. use SQL query get all tables and column schema from database
  2. transform SQL type into Golang type and Swagger Doc type
  3. use Golang Std Lib(text/template) to output Gin's handler and Route files and GORM model files
  4. os.exec call go fmt to format the output codebase

felix sshls Logic

  1. use GORM retrieve all SSH configuration from SQLite.db
  2. use olekukonko/tablewriter write table into terminal

felix ssh 9 Logic

  1. get a ssh configuration by ID
  2. use golang.org/x/crypto/ssh package start ssh session
  3. customize stdin and stdout to listen Sudo command for password message then input sudo password automatically
