4 This is an experimental tool that generates GIF animations of console
5 sessions. Like scriptreplay(1), it reads the output of script(1),
6 including timing information. Unlike scriptreplay(1), congif parses the
7 session dialogue and encodes it as a GIF animation that can be viewed on
8 graphical programs (e.g. web browsers).
14 Only dialogues generated for the Linux console can be correctly parsed
15 by congif. This means that if your $TERM environment variable is not
16 "linux" then it probably won't work. You can manually set $TERM when
17 calling script(1), but then your terminal may not work correctly while
18 the session is recorded. It's recommended that you record your sessions
19 on the Linux console itself, or on a terminal emulator that is
20 compatible with console_codes(4).
22 congif needs to know the terminal size used during the execution of
23 script(1) and this size must be constant per session (i.e. if you resize
24 the terminal while recording a session, congif won't work). By default,
25 congif assumes that the terminal size of the session is equal to the
26 current terminal size. Use the options -w and -h if you need to specify
33 A C99 compiler is needed. There are no library dependencies.
41 congif [options] timings dialogue
43 timings: File generated by script(1)'s -t option
44 dialogue: File generated by script(1)'s regular output
47 -o output File name of GIF output
48 -m maxdelay Maximum delay, as in scriptreplay(1)
49 -d divisor Speedup, as in scriptreplay(1)
50 -l count GIF loop count (0 = infinite loop)
51 -f font File name of MBF font to use
52 -h lines Terminal height
53 -w columns Terminal width
54 -c on|off Show/hide cursor
55 -q Quiet mode (don't show progress bar)
56 -v Verbose mode (show parser logs)
62 For simplicity, congif uses a custom font format, MBF. The font
63 misc-fixed [1], included in this distribution, is used by default.
65 For more information on the MBF format, see the mbf-util [2]
66 project. It includes a bdf2mbf tool that converts fonts from the
67 popular BDF format to the MBF format.
74 $ script -t 2> foo.t foo.d
76 Generating a GIF file with defaults (creates "con.gif"):
79 Generating a faster version:
80 $ congif -d3 -m1 -o fast.gif foo.t foo.d
