Práctica gh-cli-graphql

Estamos estudiando las extensiones en GitHub Cli:

Objetivos

  1. Intentaremos publicar la extensión para que sea utilizable por otros usuarios gh extension install ...
    1. Haremos un fork al espacio del usuario y renombraremos los ficheros
    2. Documentación y mejora de los mensajes

    3. Automatizaremos en lo posible las comprobaciones de error

      ➜  gh-cli-graphql-casiano-rodriguez-leon-alumnoudv5 git:(main) ✗ ./gh-repo-rename-aluXXXX -o ULL-ESIT-DMSI-1922 -r prueba-funciona  -n prueba
gh: Could not resolve to a Repository with the name 'ULL-ESIT-DMSI-1922/prueba-funciona'.
➜  gh-cli-graphql-casiano-rodriguez-leon-alumnoudv5 git:(main) ✗ ./gh-repo-rename-aluXXXX -o ULL-ESIT-DMSI-1920 -r prueba  -n prueba-antonella
gh: Name already exists on this account
    4. Publicaremos la extensión
  2. Publicaremos un módulo npm con el código js y el ejecutable en el ámbito del alumno
  3. Modificaremos la extensión para que use el módulo npm
