gdb: Guile Commands

 
 23.3.2 Guile Commands
 ---------------------
 
 GDB provides two commands for accessing the Guile interpreter:
 
 'guile-repl'
 'gr'
      The 'guile-repl' command can be used to start an interactive Guile
      prompt or "repl".  To return to GDB, type ',q' or the 'EOF'
      character (e.g., 'Ctrl-D' on an empty prompt).  These commands do
      not take any arguments.
 
 'guile [SCHEME-EXPRESSION]'
 'gu [SCHEME-EXPRESSION]'
      The 'guile' command can be used to evaluate a Scheme expression.
 
      If given an argument, GDB will pass the argument to the Guile
      interpreter for evaluation.
 
           (gdb) guile (display (+ 20 3)) (newline)
           23
 
      The result of the Scheme expression is displayed using normal Guile
      rules.
 
           (gdb) guile (+ 20 3)
           23
 
      If you do not provide an argument to 'guile', it will act as a
      multi-line command, like 'define'.  In this case, the Guile script
      is made up of subsequent command lines, given after the 'guile'
      command.  This command list is terminated using a line containing
      'end'.  For example:
 
           (gdb) guile
           >(display 23)
           >(newline)
           >end
           23
 
    It is also possible to execute a Guile script from the GDB
 interpreter:
 
 'source script-name'
      The script name must end with '.scm' and GDB must be configured to
      recognize the script language based on filename extension using the
      'script-extension' setting.  Extending GDB Extending GDB.
 
 'guile (load "script-name")'
      This method uses the 'load' Guile function.  It takes a string
      argument that is the name of the script to load.  See the Guile
      documentation for a description of this function.  (
      (guile)Loading).
