[jira] [Created] (PIG-2584) Command line arguments for Pig script
Command line arguments for Pig script
-------------------------------------
Key: PIG-2584
URL: https://issues.apache.org/jira/browse/PIG-2584
Project: Pig
Issue Type: Improvement
Components: impl
Reporter: Daniel Dai
Priority: Minor
Fix For: 0.11
We did that for Jython embeded script. It is also useful in Pig script itself:
command line: pig a.pig student.txt output
a.pig:
a = load '$1' as (a0, a1);
store a into '$2';

------------------------------------------
Nice improvement recommendation! I think dollar notation could be confused with positional reference? Agree with Jonathan, may be we should plan on using a different symbol.

---------------------------------------
why not use @1, @2, and so on, consistent with bash? @argv[1] is pretty ugly...

---------------------------------
Oh yes, we cannot use $1, $2, maybe $argv[1], $argv[2]?

---------------------------------------
Agree 400% that this is useful, though do we want to do $1, $2, etc? It is a bit confusing given the $name syntax we also have... I guess we can just distinguish between $number and $name.
