**-e**

**--editor**

-

  Tells the debugger to open source files using the host's "external editor" mechanism.

-

  Chooses the language for the REPL.

-

  Notes:

- Multiple "-s" and "-o" options can be provided.

  They will be processed

-

  from left to right in order, with the source files and commands interleaved.  The same is true of the "-S" and "-O" options.  The before file and after file sets can intermixed freely, the command parser will sort them out.  The order of the file specifiers ("-c", "-f", etc.) is not significant in this regard.

-

  If you don't provide **-f** then the first argument will be the file to be debugged which means that 'lldb **--** \<filename\> \[\<ARG1\> \[\<ARG2\>\]\]' also works.  But remember to end the options with "--" if any of your arguments have a "-" in them.
