Installation

$ pip install ansiescapes

Usage

import ansiescapes
import sys

# Moves the cursor two rows up and to the left
sys.stdout.write(ansiescapes.cursorUp(2) + ansiescapes.cursorLeft)
#=> '\u001B[2A\u001B[1000D'

API

cursorTo(x, [y])

Set the absolute position of the cursor. x0 y0 is the top left of the screen.

cursorMove(x, [y])

Set the position of the cursor relative to its current position.

cursorUp(count)

Move cursor up a specific amount of rows. Default is 1.

cursorDown(count)

Move cursor down a specific amount of rows. Default is 1.

cursorForward(count)

Move cursor forward a specific amount of rows. Default is 1.

cursorBackward(count)

Move cursor backward a specific amount of rows. Default is 1.

cursorLeft

Move cursor to the left side.

cursorSavePosition

Save cursor position.

cursorRestorePosition

Restore saved cursor position.

cursorGetPosition

Get cursor position.

cursorNextLine

Move cursor to the next line.

cursorPrevLine

Move cursor to the previous line.

cursorHide

Hide cursor.

cursorShow

Show cursor.

eraseLines(count)

Erase from the current cursor position up the specified amount of rows.

eraseEndLine

Erase from the current cursor position to the end of the current line.

eraseStartLine

Erase from the current cursor position to the start of the current line.

eraseLine

Erase the entire current line.

eraseDown

Erase the screen from the current line down to the bottom of the screen.

eraseUp

Erase the screen from the current line up to the top of the screen.

eraseScreen

Erase the screen and move the cursor the top left position.

scrollUp

Scroll display up one line.

scrollDown

Scroll display down one line.

clearScreen

Clear the terminal screen.

beep

Output a beeping sound.

image(input, [options])

Display an image.

Currently only supported on iTerm2 >=3

See termimg for a higher-level module.

input

Type: Buffer

Buffer of an image. Usually read in with open.

Example:

import ansiescapes
import sys
from codecs import open

with open('image.png', 'rb') as imageFile:
  f = imageFile.read()
  b = bytearray(f)

sys.stdout.write(ansiescapes.image(b))

options

width

height

Type: string number

The width and height are given as a number followed by a unit, or the word "auto".

• `N`: N character cells.
• `Npx`: N pixels.
• `N%`: N percent of the session's width or height.
• `auto`: The image's inherent size will be used to determine an appropriate dimension.

preserveAspectRatio

Type: boolean

Default: true

setCwd([path])

Type: string

Default: os.getcwd()

Inform iTerm2 of the current directory to help semantic history and enable Cmd-clicking relative paths.

ansiescapes's Issues

AttributeError: 'str' object has no attribute 'escape'

Already fixed it

Implement more escape codes from ANSI X3.64

See https://en.wikipedia.org/wiki/ANSI_escape_code for a list of escape codes. I'm in a rush right now: I will enumerate what's missing later today.

No ansiescapes release with the fix for the `TERM_PROGRAM` issue.

Ansiescapes has a fix for TERM_PROGRAM issue merged in master, but there's no release for it; notably, pypi is still serving version 1.0.0, which does not contain the fix.

Exception on str decode & making it work in terminal

ansiescapes/ansiescapes.py

Line 8 in 25a4b90

def _(s): return s.decode('unicode_escape');

I'm in no way python enthusiast but this line results in error:

  File "/home/pholat/.local/lib/python3.6/site-packages/ansiescapes.py", line 8, in _
    def _(s): return s.decode('unicode_escape');
AttributeError: 'str' object has no attribute 'decode'

So shouldn't it be decode?
Also to actually use to manipulate terminal with sys.stdout.buffer.write imho ESC should be:
\033[ although there is character [ added, while it's not a part of escape key :) as well as it shouldn't be ansii_escaped so that it would actually work.
