   9  Paging capabilities for IPython.core
  10  
  11  Notes
  12  -----
  13  
  14  For now this uses IPython hooks, so it can't be in IPython.utils.  If we can get
  15  rid of that dependency, we could move it there.

  40      This is called by page(). It can raise an error (e.g. when run in the
  41      test suite), so it's separated out so it can easily be called in a try block.

  55  
  56      strng can be a mime-bundle dict, supplying multiple representations,
  57      keyed by mime-type.
  58  
  59      The screen_lines parameter specifies the number of *usable* lines of your
  60      terminal screen (total lines minus lines you need to reserve to show other
  61      information).
  62  
  63      If you set screen_lines to a number <=0, page() will try to auto-determine
  64      your screen size and will only use up to (screen_size+screen_lines) for
  65      printing, paging after that. That is, if you want auto-detection but need
  66      to reserve the bottom 3 lines of the screen, use screen_lines = -3, and for
  67      auto-detection without any lines reserved simply use screen_lines = 0.
  68  
  69      If a string won't fit in the allowed lines, it is sent through the
  70      specified pager command. If none given, look for PAGER in the environment,
  71      and ultimately default to less.
  72  
  73      If no system pager works, the string is sent through a 'dumb pager'
  74      written in python, very simplistic.

  93  
  94      Pager is dispatched via the `show_in_pager` IPython hook.
  95      If no hook is registered, `pager_page` will be used.
