New Features

  • What feature(s) did you add?
  • I have added a more advanced shell to the fantasy console, that allows the user to chain commands.
    It currently allows for running the new shell in a non-interactive mode.
  • Currently, it allows for the chaining of commands conditionally (&) or unconditionally (;).
  • In conditional chaining the next command only runs if the last command exited successfully, and in unconditional chaining, the next command runs no matter what happened with the last.

  • How did you implement it/them?
  • I modified the general terminal code, to return the result of ran commands, allowing conditional chaining of commands.
  • At first, it used code in the xshell program for parsing. Now, however, it organizes the code better through use of the built-in language parser to parse the input, and interpret it as a chain of commands separated by characters.
  • This edit contains two new files, one contains the new language for the parsing system, and the other contains the main program for xhsell.
  • The existing programs still need to be modified to return their error status, to further improve xshell's conditional chaining.
  • A lot of the code that was used was already used in parts of LIKO-12
