            Bug ID: 38520
           Summary: no pager for help.
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at lists.llvm.org
          Reporter: peeter.joot at lzlabs.com

If I invoke the lldb help on a given topic, most of it flies off the screen.
Example:

(lldb) help expression

It would make sense for the lldb help to be paged like gdb (and probably to use
that pager for other long text too).

I understand that there are various workarounds, like using a terminal window
with a scrollbar (provided you don't use a multiplexer like screen, which
messes that up).  The best work around for help appears to be something like
the following from another window:

lldb -b -O 'help expression' | less

which is still somewhat clumsy, especially compared to the ease of use of gdb
help.
