Hi, all:
After several rounds of discussion, I think that adding a -t option to the
`info mtree` command, which enables the display of tree-like node characters
(e.g., +--, |--), is a better approach.
As BALATON Zoltan pointed out, retaining space-based indentation for displaying
memory region (mr) nodes helps ensure that the output remains easily parseable
by other programs. This also provides better compatibility with existing tools
and scripts.
If people really feed the output of HMP info mtree to parsers, we should
probably provide the information via QMP.
Thank you for your helpful advice. I think the next step is to try
implementing "info mtree" via QMP first, and then have it called by HMP.
I’ve added it to my to-do list, and I’ll try to implement it using QMP
in the next phase.
Users can choose between:
- Without '-t': The default format using spaces for indentation, suitable for
scripting and parsing;
- With '-t': The tree-style format using visual characters, ideal for
human-readable output.
This way, both usability and compatibility are preserved.
Maintaining compatibility is a choice in HMP, not a requirement. I'm
not judging, mind.
