<tmdoc-title|Creating sessions>
|
|
|
|
A session can be started from the <menu|Insert|Session> menu. Since
|
|
<TeXmacs> is based on the <name|Scheme> language, it is always possible to
|
|
start a <name|Scheme> session using <menu|Insert|Session|Scheme>. On
|
|
<name|Unix> systems, it is usually also possible to start <name|Bash> shell
|
|
sessions using <menu|Insert|Session|Shell>. The remainder of the items in
|
|
the <menu|Insert|Session> menu depend on the plug-ins which are installed
|
|
on your system.
|
|
|
|
A session consists of a sequence of input and output fields and possible
|
|
text between them. When pressing <shortcut|(kbd-return)> inside an input
|
|
field of a session, the text inside the environment is evaluated and the
|
|
result is displayed in an output field.
|
|
|
|
When entering a command in a session, the application attempts to execute
|
|
it. Several commands may be launched concurrently in the same document, but
|
|
the output will only be active in the session where the cursor is and at
|
|
the place of the cursor. Therefore, we recommend to use different buffers
|
|
for parallel executions.
|
|
|
|
For each type of extern application, one may choose between sharing a
|
|
single process by different sessions, or launching a separate process for
|
|
each different session. More precisely, when inserting a session using
|
|
<menu|Insert|Session|Other>, you may specify both a ``session type''
|
|
(Shell, Pari, Maxima, <abbr|etc.>) and a ``session name'' (the default name
|
|
is ``default''). Sessions with different names correspond to different
|
|
processes and sessions with the same name share a common process.
|
|
|
|
In order to finish the process which underlies a given session, you may use
|
|
<menu|Session|Close session>. When pressing <shortcut|(kbd-return)> in the
|
|
input of a non-connected system, the system will be restarted
|
|
automatically. You may also use <menu|Session|Interrupt execution> in order
|
|
to interrupt the execution of a command. However, several applications do
|
|
not support this feature.
|
|
|
|
In order to evaluate all fields of <abbr|e.g.> a previously created
|
|
session, you may use <menu|Session|Evaluate|Evaluate all>. Similarly,
|
|
<menu|Session|Evaluate|Evaluate above> and <menu|Session|Evaluate|Evaluate
|
|
below> allow you to evaluate all field above or below the current field.
