Add autoterminal

[basxto]

It’s not finished yet.
A PTY and multithreading is used now.
Terminal capabilities get communicated via a custom terminfo file.

• The makefile needs some improvement since I’m currently linking all modules against libutil and pthread.

Broken:

• ncurses looks shifted
  
• lolcat doesn’t end

Also do:

• clean up code
• outsource the writing logic for cyriax

Small review:

• use oscore (src/oscore.h) insted of pthread directly
• fix code formatting, make CI compile this successfully

Code looks good, now that it allocates a PTY and does threading, it's really nice! :)

[basxto]

* make CI compile this successfully

build.sr.ht needs to have ncurse installed, otherwise it can’t compile the terminfo file with tic

Codecy is just rediculous.

[basxto]

Apparently parse_sgr_value breaks for default values.
But htop looks a bit weird on that terminal

Edit: htop expects bold black to be gray hishamhm/htop#35

• Evaluate how to support ANSI graphics (ponysay, doge)

[vifino]

Code looks good now!
Just a few nitpicks.

[vifino]

You should store the thread handle and join it when it is done, otherwise you'll be leaking memory.

[basxto]

oscore_event_* is not suitable, I don’t wanna block draw. I need some polling.
I always draw the buffer and I only want to do the autotyping if no child process is running.

You can add ncurses to packages: in .builds/freebsd.yml. We should perhaps bundle a precompiled terminfo as to not require ncurses everywhere.

Travis complains differently... https://travis-ci.com/shinyblink/sled/jobs/274459240#L262

tic -o terminfo autoterminal.terminfo
"autoterminal.terminfo", line 12, col 34, terminal 'autoterminal': Illegal character - 'M-t'
"autoterminal.terminfo", line 12, col 34, terminal 'autoterminal': Entry does not start with terminal names in column one

Codecy is just rediculous.

shrug

[basxto]

tic also fails on Mac, make just does not notice.
And builds.sr.ht does not draw my terminal, where do I have to add it?

[vifino]

Can you prefix it? Having something global with clear_buffer etc.. is bound to cause trouble.

[basxto]

I postfixed it for whatever reason, I think I’ll go with:

#include "printbuffer.h"
printbuffer_init_default();
printbuffer_write_default("foo", 12, 42);//just writes to the buffer
// write understands \n and \r, but \r will jump to column 0
printbuffer_draw_default();//draws whole buffer
printbuffer_deinit();

EDIT: I renamed it

[basxto]

Altchars 🙌

while true; do echo " "; sleep 1; done | myman

asciiquarium is nearly flawless now, I do have some general drawing issues with the last column and line

htop looks a lot better now, but some text is still hidden and I have no idea what weird stuff it’s doing there.

[basxto]

• Add UTF-8 detection: Show one unprintable character instead of up to 4

[basxto]

pipes.sh -t 2 uses unicode instead of altchars, but I understand that too.

[basxto]

Ponysay works now too 😁

EDIT: and doge

[vifino]

That is incredible!

[basxto]

TERM=xterm-256color tmux

[basxto]

It’s pretty much finnished now. I think it could be merged as soon as I support multiple scripts.
Stuff that’s left to do: (Don’t consider them very high priority)

• Allow multiple scripts and randomly load one on reset
• Look into tic errors on builds.sr.ht
• Find out why asciiquarium sometimes draws characters on the wrong side
• Find out why htop shows no text (TERM=xterm-256color htop works more or less)
• Check whether I can link only autoterminal against libutil
• Punch Codacy

[basxto]

• kill child process on deinit

[basxto]

htop is finally working!

[basxto]

I added a little utility script that sends /next to fish after some specified time.
Things like ./next 10 & while true; do echo " "; sleep 1; done | myman are now possible.
timeout sadly does not work with piping.

EDIT: Since htop does not fit on the screen, it can also make use of this.

./next 30 & while true; do sleep 5; echo '^'; sleep 5; echo '$'; done | htop
