Re: [mat-dev] New Feature Requirement: Enhance MAT working under command line.

Hi Dian Guo (and rest of MAT team),

Please provide comments on a proposed new feature to support your request "(b)" to compare two heapdumps from the command line and print the histogram difference as text: https://bugs.eclipse.org/bugs/show_bug.cgi?id=483418

> Run this compare function in command line.

Given that org.eclipse.mat.api.parse only accepts a single dump path, it seems MAT will need a new application extension which accepts more than one dump. My first thought is that it only takes two dumps so that it's clear (by convention) which is the baseline, in which case the new extension should probably be solely a "compare" extension.

Dear development team:

This is a new feature requirement, not sure if it can be implemented or not.

When considering to integrate the memory analysis in the automation procedure, we'd like MAT behavior could work under command line. The current requirement is:

a. Export the whole histogram to a txt file. Current Eclipse Memory Analyzer can show histogram in GUI.
b. The Eclipse Memory Analyzer can compare two heapdumps, Run this compare function in command line.
c. And export the compare result to a txt file.

Thanks!
