Prompts

Module: Prompts

Inheritance diagram for IPython.Prompts:

Classes for handling input/output prompts.

Classes

BasePrompt

class IPython.Prompts.BasePrompt(cache, sep, prompt, pad_left=False)

Bases: object

Interactive prompt similar to Mathematica’s.

__init__()

cwd_filt()

Return the last depth elements of the current working directory.

$HOME is always replaced with ‘~’. If depth==0, the full path is returned.

cwd_filt2()

Return the last depth elements of the current working directory.

$HOME is always replaced with ‘~’. If depth==0, the full path is returned.

p_template

Template for prompt string creation

set_p_str()

Set the interpolating prompt strings.

This must be called every time the color settings change, because the prompt_specials global may have changed.

write()

CachedOutput

class IPython.Prompts.CachedOutput(shell, cache_size, Pprint, colors='NoColor', input_sep='n', output_sep='n', output_sep2='', ps1=None, ps2=None, ps_out=None, pad_left=True)

Class for printing output from calculations while keeping a cache of reults. It dynamically creates global variables prefixed with _ which contain these results.

Meant to be used as a sys.displayhook replacement, providing numbered prompts and cache services.

Initialize with initial and final values for cache counter (this defines the maximum size of the cache.

__init__()

display()

Default printer method, uses pprint.

Do ip.set_hook(“result_display”, my_displayhook) for custom result display, e.g. when your own objects need special formatting.

flush()

set_colors()

Set the active color scheme and configure colors for the three prompt subsystems.

update()

Prompt1

class IPython.Prompts.Prompt1(cache, sep='n', prompt='In [\#]: ', pad_left=True)

Bases: IPython.Prompts.BasePrompt

Input interactive prompt similar to Mathematica’s.

__init__()

auto_rewrite()

Print a string of the form ‘—>’ which lines up with the previous input string. Useful for systems which re-write the user input when handling automatically special syntaxes.

set_colors()

Prompt2

class IPython.Prompts.Prompt2(cache, prompt=' .\D.: ', pad_left=True)

Bases: IPython.Prompts.BasePrompt

Interactive continuation prompt.

__init__()

set_colors()

set_p_str()

PromptOut

class IPython.Prompts.PromptOut(cache, sep='', prompt='Out[\#]: ', pad_left=True)

Bases: IPython.Prompts.BasePrompt

Output interactive prompt similar to Mathematica’s.

__init__()

set_colors()

Functions

IPython.Prompts.multiple_replace()

Replace in ‘text’ all occurences of any key in the given dictionary by its corresponding value. Returns the new string.

IPython.Prompts.str_safe()

Convert to a string, without ever raising an exception.

If str(arg) fails, <ERROR: ... > is returned, where ... is the exception error message.
