Is -s option required?

[soichih]

I have a tty record file, but I don't know what width/height it was recorded on. Do I need to know the size before running this tool? In another words, is -s option required?

If I run it without -s option, I get following error message.

Hello,

Yes, size is required. Unfortunately, this information is not recorded in a ttyrec file. You might have to try different values.

Wow. really? It sounds like a serious lack of metadata for ttyrec.

[dtinth]

Yeah, ttyrec just stores the raw terminal data along with time
information.

See the wikipedia page
for more information.

I see.. So this warrants a need to implement ttyrec wrapper with its own data formats that can contain ttyrec data along with the display size; similar to .avi .mpg being a wrapper around the raw codec..

From the Wikipedia page, termrec already
does it. It injects both the encoding information and terminal size
using few control sequences. Maybe that does what you want.

However, right now, tty2js does not parse it. Right now you can parse it
for yourself and put it in the -s option.

yo, i modified ttyrec and made my own version that contains these
metadata.. and much much more.. the output format is no longer compatible
to ttyrec. I'm still planning to add a ctrl key sequence, to signal when to
do capture and when not to, as often times there are times we do extra
stuff in commandline that we do not intend to be part of the record. There
are more features, still i will not mentioned here..
