Marc André Tanner 8f80aa8044 Do not implicilty enable passthrough mode if no session name is given 
Even when no session name was provided the passthrough flag was still
implicitly enabled in case stdin was not a terminal. This behavior
prevented the session list from being printed i.e.

  abduco < /dev/null

would not work as expected. Only enable implicit passthrough if stdin
is not a terminal *and* a session name is given.

Fix #34
 2018-05-16 10:57:39 +02:00
Marc André Tanner c33ee37b43 Expose current session socket as $ABDUCO_SOCKET 
This is an absolute path to the Unix domain socket representing the
current session.

Marc André Tanner 4c3e2c8c70 Expose current session name as $ABDUCO_SESSION 
The supervised command can use it to determine in which session it
is running. It is not necessarily identical to the file name of the
underlying socket as stored in the file system.

Marc André Tanner fd34b98db7 Add explicit option for command pass through 
This allows commands to be send interactively (i.e. when stdin refers
to a terminal). Also imply attach action if none is given, hence:

    $ abduco -p session
    cowsay hi
    ^D

can also be used to send input to a session.
 2018-03-17 13:30:52 +01:00
Marc André Tanner c901f2bbb8 If stdin is not a terminal pass-through its data to the session 
This allows to send commands to a running session:

    echo cowsay hi | abduco -a session

See #8 for initial discussion of the feature.

Marc André Tanner 8964601fe1 Use fixed size integer types in protocol messages 
This should make it possible to connect with a 32bit client to a 64bit
server. This might also make it possible to forward the abduco socket
over SSH as described in #25. Different endianness are not supported at
this time.

This is a breaking protocol change. Make sure to use the same version
as client and server (anything else is unsupported anyway!).

Marc André Tanner fdd0c4163f Use the shell to execute default command given by $ABDUCO_CMD 
This allows to specify a default command with arguments as in:

 $ ABDUCO_CMD="dvtm -m ^b" abduco -c demo
 2016-01-07 23:50:47 +01:00
Marc André Tanner 598fdc396f Print session list if neither action nor session name was given 
In particular

 $ abduco -e ^q

will now also print the session list which is useful if the
default detach key is changed by means of a shell alias.

Marc André Tanner 75dc9a52fa Update usage message to include -l option 2016-01-03 12:02:39 +01:00
Luke Clifton 1fcd6e4f44 Added -l option to move clients to the bottom of the stack. 
This means it wont take control over the window size until
it is the last remaining one, unless another client connects
with the -l option set at a later time.

Marc André Tanner 57e7acba69 Display more meaningful time in session list 
Due to the stale session detection logic we will always access
the socket thus essentially printing the current time which
does not seem useful.

Marc André Tanner 277f4d154d Improve detection and handling of stale sessions 
With this it should be possible to create sessions for which a
dead left over socket still exists. Also the session list as
printed by abduco without any arguments will delete those stale
sockets.

Ross Mohn 91feaaa9f9 Fix strange behavior with abduco -A 
Here are the steps:

1) Run 'abduco -A foo ping suckless.org'

2) Press 'CTRL+\' to detach

3) Run 'abduco -A foo' to reattach

4) Press 'CTRL+\' and it flashes the screen but does not detach

5) Press 'CTRL+\' a second time and it detaches this time

Here's what the output looks like:

    $ abduco -A foo ping suckless.org
    abduco: foo: detached
    $ abduco -A foo
    abduco: foo: detached
    abduco: foo: detached
    $

Also, oddly, I am only seeing this behavior on my Ubuntu Linux host, not
my AIX hosts.

Marc André Tanner ca60dc72f4 Improve -f handling 
As an example -A -f should probably not create a new session
if the old one is still running.

yy 0102cf840e Remove -C mode, in favour of a -f flag 
that works with -c, -n or -A, which forces the creation of a
new session when there is an existing but already terminated
session of the same name.
