604829 - more helpful usage info for js -h

Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect)

Description

[Dave Herman [:dherman]]

The JS shell produces a pretty cryptic usage info, and I can never remember which toggles take which characters. I'll submit a patch with more detailed usage info.

Instead of this, please say:

>+    fprintf(gErrFile, "  -w            Report strict warnings\n"
>+                      "  -W            Do not report strict warnings\n"
>+                      "  -x            Toggle JSOPTION_XML flag\n"
>+                      "  -C            Compile-only; do not execute\n"
>+                      "  -i            Enable interactive read-eval-print loop\n"
...

until you get down to the part where you're actually printf-ing something, of course. r=me with that, and thanks.
