This serie of patches try fix the problem of the timeout in main loop, which
causes st wakeup each 20 ms even thare is noting to do.
Please send comments and suggestion.
Best regards.

The main loop waits until there is some data to read in file descriptors of
the X server or the pseudo tty. But it uses a timeout in select(), which
causes that st awake each 20 ms, even it doesn't have something to do. This

I'm not exactly sure what this feature will be used for. If you want
to script something around a program expecting to run in a term there
are already better tools for that like expect [1]. I'm not the one who
added this goal.

The timeout problem was introduced to speed up the rendering when a
lot of text is printed.
The logic is basically to not redraw on every read when the throughput is
high:
I tried do the same thing putting the draw at the end of the loop, so if you
have a high throughput you will read more
Maybe a way to improve my patches is testing is some data can be read from
the file descriptors and in this case continue the loop. something like:
if(i++ 4) {
struct timeval tv = {0};
FD_ZERO(rfd);
FD_SET(cmdfd, rfd);
If the only use is to debug it shouldn't be exposed to users and it's
I only implemented a goal of the project (I don't know who insert that goal

The ‐f switch allows easy recording of st sessions and so is useful to
the users.
It would be a useful feature for me, acting as a kind of easier to
deal with scrollback thing, for when there's a good deal of text
that flew by, that I need to read, or copy elsewhere

Thinking a bit about it, it is true that you can get the session using
'script -f', and it is not necessary insert this feature inside of st.

Well, you can use a named pipe and script -f, cat -v. But I think this is
too much complex, and the cost of -f option is minimum and don't
