Make any terminal app into server/client. Basically
single-window-single-panel tmux(1), but dumber.
$ ./build # or just cc *.c -o daety
$ ./daety --help
Usage: ./daety [opts] <prog> [<args...>]
--help -h display this help
--version show the build version
--list -l list known (local) servers
--kill terminate the server
shared client/server:
--id -i <id> the default is form prog and args
--addr -a <addr> similar to id, but for an IP address
addr and id are mutually exclusive;
addr should be of the form
IPv4: '123.123.123.123:1234'
server only:
--server -s starts only the server
--cwd -C change working directory
--quiet -q do not output anything, and
--verbose output everything going through;
by default the server outputs some
information on what it going on
--track (also when starting first client)
the server will keep track on all
the program sent, and stream it back
to new incoming clients
client only:
--key -k <key> use the following leader key
(use ^x notation for controls)
--cmd -c <keys..> --
send the sequence upon connection
(joined with no separator); it
must be terminated with -- even
if there are no args after it
(use ^x notation for controls)
an empty string indicates that the
client should stop after sending
--cooked do not set raw mode; in that case
the leader key has no meaning$ ./daety vi # in one terminal
... (vi)
$ ./daety -c '^[^[:e ' README.md ^M -- vi # in another terminal
... (same vi)daety prog args... will start prog on a server if an
existing instance was not already started with the exact
same arguments. Then it connects a client to interract
with the program. If a server already existed, a client is
created and connected to it. Multiple client can connect
to a same server.
Options for daety must be position before prog. --
is recognised as ending the options.
--id/-i can be used to identify a server not by
the combination of arguments. A server can be started
explicitely with --server/-s. It will then not be
a daemon. IDs have a max length of 1019.
Client can be specified a 'leader key' with --key/-k.
The ^ notation is used (for example esc is ^[, see
showkey -a). The default is ^\. The leader key is used
to talk with the client itself:
<key>^C: terminate the server, close the client<key>^D: close the client, keep the server<key>^Z: pause the client (SIGTSTP)
By default, the client sets itself into raw mode, ie
each key press is immediately sent to the server. To
keep in cooked mode (typically when the program is not an
interactive TUI), --cooked can be used.
Both the client and the server are perfectly dumb and
oblivious to transiting bytes. Nothing is stored (well
except for --track). However, the server scans the
program's output to track entering / leaving alternate
buffer, and the client scans for the leader key.
