idlwave: Starting the Shell

 
 5.1 Starting the Shell
 ======================
 
 The IDLWAVE shell can be started with the command ‘M-x idlwave-shell’.
 In ‘idlwave-mode’ the function is bound to ‘C-c C-s’.  It creates a
 buffer ‘*idl*’ which is used to interact with the shell.  If the shell
 is already running, ‘C-c C-s’ will simply switch to the shell buffer.
 The command ‘C-c C-l’ (‘idlwave-shell-recenter-shell-window’) displays
 the shell window without selecting it.  The shell can also be started
 automatically when another command tries to send a command to it.  To
 enable auto start, set the variable ‘idlwave-shell-automatic-start’ to
 ‘t’.
 
    In order to create a separate frame for the IDLWAVE shell buffer,
 call ‘idlwave-shell’ with a prefix argument: ‘C-u C-c C-s’ or ‘C-u C-c
 C-l’.  If you always want a dedicated frame for the shell window,
 configure the variable ‘idlwave-shell-use-dedicated-frame’.
 
    To launch a quick IDLWAVE shell directly from a shell prompt without
 an IDLWAVE buffer (e.g., as a replacement for running inside an xterm),
 define a system alias with the following content:
 
      emacs -geometry 80x32 -eval "(idlwave-shell 'quick)"
 
    Replace the ‘-geometry 80x32’ option with ‘-nw’ if you prefer the
 Emacs process to run directly inside the terminal window.
 
    To use IDLWAVE with ENVI or other custom packages which change the
 ‘IDL> ’ prompt, you must change the ‘idlwave-shell-prompt-pattern’,
 which defaults to ‘"^ ?IDL> "’.  Normally, you can just replace the
 ‘IDL’ in this expression with the prompt you see.  A suitable pattern
 which matches the prompt for both ENVI and IDL simultaneously is ‘"^
 ?\\(ENVI\\|IDL\\)> "’.
 
  -- User Option: idlwave-shell-explicit-file-name (‘idl’)
      This is the command to run IDL.
 
  -- User Option: idlwave-shell-command-line-options
      A list of command line options for calling the IDL program.
 
  -- User Option: idlwave-shell-prompt-pattern
      Regexp to match IDL prompt at beginning of a line.
 
  -- User Option: idlwave-shell-process-name
      Name to be associated with the IDL process.
 
  -- User Option: idlwave-shell-automatic-start (‘nil’)
      Non-‘nil’ means attempt to invoke idlwave-shell if not already
      running.
 
  -- User Option: idlwave-shell-initial-commands
      Initial commands, separated by newlines, to send to IDL.
 
  -- User Option: idlwave-shell-save-command-history (‘t’)
      Non-‘nil’ means preserve command history between sessions.
 
  -- User Option: idlwave-shell-command-history-file
           (‘~/.emacs.d/idlwave/.idlwhist’)
      The file in which the command history of the idlwave shell is
      saved.  Unless it’s an absolute path, it goes in
      ‘idlwave-config-directory’.
 
  -- User Option: idlwave-shell-use-dedicated-frame (‘nil’)
      Non-‘nil’ means IDLWAVE should use a special frame to display the
      shell buffer.
 
  -- User Option: idlwave-shell-use-dedicated-window (‘nil’)
      Non-‘nil’ means use a dedicated window for the shell, taking care
      not it replace it with other buffers.
 
  -- User Option: idlwave-shell-frame-parameters
      The frame parameters for a dedicated idlwave-shell frame.
 
  -- User Option: idlwave-shell-raise-frame (‘t’)
      Non-‘nil’ means ‘idlwave-shell’ raises the frame showing the shell
      window.
 
  -- User Option: idlwave-shell-temp-pro-prefix
      The prefix for temporary IDL files used when compiling regions.
 
  -- User Option: idlwave-shell-mode-hook
      Hook for customizing ‘idlwave-shell-mode’.
