[jira] [Commented] (ARROW-12735) [C++][Dev] Write gdb plugin

    [ https://issues.apache.org/jira/browse/ARROW-12735?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17342787#comment-17342787 ] 

Weston Pace commented on ARROW-12735:
-------------------------------------

+1  for this.  I played  around with it a bit.   Some specific features that would be nice:

 
 * Better pretty printing of `Datum`, right now I think it shows up as a giant variant blob
 * Ability to easily get at the buffers of an array and visualize them as hex
 * gdb functions that hook into the Arrow pretty print methods

> One common issue when using gdb with Arrow is that it's non-trivial to explore and display Arrow data and metadata using built-in gdb functionality. One usually needs lots of hand typing of expressions.
> One way to alleviate this would be to write a gdb plugin giving a higher-level view of Arrow C++ objects. This should be possible using the gdb Python API (though not trivial):
> https://sourceware.org/gdb/current/onlinedocs/gdb/Python.html#Python
> A sophisticated example of this is the gdb plugin for Python itself:
