ttygif 1.0.718

A asciicast to gif utility

ttygif

A self contained asciicast data file to gif conversion utility

install

pip install ttygif --user

It's portable

ttygif is self contained with no dependencys other than python. GIF encoding and termal emulation are both implimented with internal cython code. The terminal font is embeded within the code. All you need to get ttygif to work is a c compiler, python and its development libs. ttygif is a cython project.

usage

ttygif version 1.0.287
usage: ttygif [-h] [--input FILE] [--output FILE] [--loop COUNT] [--delay MS]
              [--fps FPS]

tty output to gif

optional arguments:
  -h, --help     show this help message and exit
  --input FILE   asciinema .cast file (default: None)
  --output FILE  gif output file (default: None)
  --loop COUNT   number of loops to play, 0=unlimited (default: 0)
  --delay MS     delay before restarting gif in milliseconds (default: 1000)
  --fps FPS      encode at (n) frames per second (0-25) 0=speed of cast file
                 (default: 8)

# Example
#ttygif --input data/232377.cast --output 232377.gif --fps=10

status

• full output terminal emulation support not ready
• support for standard I/O -> Done
• support for colors -> Done
• support for cursor positioning -> Done
• Support for erase line modes 1,2,3 -> Done
• Support for erase screen -> Done

Normal/colorized output work fine.

Features still left to handle

• documentation
• time period ( capture partial recording based on time stamps x-y)
• add progress bar to top/bottom of gif with n of y H:M:I:S
• font generation app
• font mapping for utf 8,16,13 characters to base 256 map
• palette flags, monochrome, grayscale, system, custom, count [n]<256
• gif color consoladataion, for lower bit count (<8) compression
• piped stdout with auto cast generation/emulated timestamps
• asciicast v1 support
• gif error handeling
• file io error handeling
• cursor position saving
• cursor emulation
• erase screen with default bg color
• overflow on cursor position out of bounds
• cythonic definitions for speed improvment - Mostly Done
• image underlay (branding)
• image overlay (branding)
• cliping
• origin x,y
• logging with ansi stripping
• split every n seconds or size
• export as frames
• theme/solarized/bright/microsoft

Profile Times

• minimal speed gains have been put into place about 40% original speed increase
• an additional 20-30% boost once I update to cythonic variables
• 38% drawing characters
• 23% converting stream text to bufer
• 18% frame bounding for giff diff's
• 14% compressing image frames
• 07% other

Notes

asciicast may split data between events, causing escape codes not to be recognised. ttygif moves all trailing unformed escape codes to the next event.
