install

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.

• piped stdout with auto cast generation/emulated timestamps
• asciicast v1 support
• documentation
• gif error handeling
• file io error handeling
• cursor position saving

• erase screen with default bg color
• overflow on cursor position out of bounds
• cythonic definitions for speed improvment
• image underlay (branding)
• image overlay (branding)
• palette flags, monochrome, grayscale, system, custom, count [n]<256
• font generation app
• font mapping for utf 8,16,13 characters to base 256 map
• add progress bar to top/bottom of gif with n of y H:M:I:S
• gif color consoladataion, for lower bit count (<8) compression

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
