cmd — Support for line-oriented command interpreters Source code: Lib/cmd.py The Cmd class provides a simple framework for writing line-oriented command interpreters. These are often useful for test harnesses, administrative tools, and prototypes that will later be wrapped in a more sophisticated interface.
class cmd... | python.library.cmd |
class cmd.Cmd(completekey='tab', stdin=None, stdout=None)
A Cmd instance or subclass instance is a line-oriented interpreter framework. There is no good reason to instantiate Cmd itself; rather, it’s useful as a superclass of an interpreter class you define yourself in order to inherit Cmd’s methods and encapsulate a... | python.library.cmd#cmd.Cmd |
Cmd.cmdloop(intro=None)
Repeatedly issue a prompt, accept input, parse an initial prefix off the received input, and dispatch to action methods, passing them the remainder of the line as argument. The optional argument is a banner or intro string to be issued before the first prompt (this overrides the intro class at... | python.library.cmd#cmd.Cmd.cmdloop |
Cmd.cmdqueue
A list of queued input lines. The cmdqueue list is checked in cmdloop() when new input is needed; if it is nonempty, its elements will be processed in order, as if entered at the prompt. | python.library.cmd#cmd.Cmd.cmdqueue |
Cmd.completedefault(text, line, begidx, endidx)
Method called to complete an input line when no command-specific complete_*() method is available. By default, it returns an empty list. | python.library.cmd#cmd.Cmd.completedefault |
Cmd.default(line)
Method called on an input line when the command prefix is not recognized. If this method is not overridden, it prints an error message and returns. | python.library.cmd#cmd.Cmd.default |
Cmd.doc_header
The header to issue if the help output has a section for documented commands. | python.library.cmd#cmd.Cmd.doc_header |
Cmd.emptyline()
Method called when an empty line is entered in response to the prompt. If this method is not overridden, it repeats the last nonempty command entered. | python.library.cmd#cmd.Cmd.emptyline |
Cmd.identchars
The string of characters accepted for the command prefix. | python.library.cmd#cmd.Cmd.identchars |
Cmd.intro
A string to issue as an intro or banner. May be overridden by giving the cmdloop() method an argument. | python.library.cmd#cmd.Cmd.intro |
Cmd.lastcmd
The last nonempty command prefix seen. | python.library.cmd#cmd.Cmd.lastcmd |
Cmd.misc_header
The header to issue if the help output has a section for miscellaneous help topics (that is, there are help_*() methods without corresponding do_*() methods). | python.library.cmd#cmd.Cmd.misc_header |
Cmd.onecmd(str)
Interpret the argument as though it had been typed in response to the prompt. This may be overridden, but should not normally need to be; see the precmd() and postcmd() methods for useful execution hooks. The return value is a flag indicating whether interpretation of commands by the interpreter shoul... | python.library.cmd#cmd.Cmd.onecmd |
Cmd.postcmd(stop, line)
Hook method executed just after a command dispatch is finished. This method is a stub in Cmd; it exists to be overridden by subclasses. line is the command line which was executed, and stop is a flag which indicates whether execution will be terminated after the call to postcmd(); this will be... | python.library.cmd#cmd.Cmd.postcmd |
Cmd.postloop()
Hook method executed once when cmdloop() is about to return. This method is a stub in Cmd; it exists to be overridden by subclasses. | python.library.cmd#cmd.Cmd.postloop |
Cmd.precmd(line)
Hook method executed just before the command line line is interpreted, but after the input prompt is generated and issued. This method is a stub in Cmd; it exists to be overridden by subclasses. The return value is used as the command which will be executed by the onecmd() method; the precmd() implem... | python.library.cmd#cmd.Cmd.precmd |
Cmd.preloop()
Hook method executed once when cmdloop() is called. This method is a stub in Cmd; it exists to be overridden by subclasses. | python.library.cmd#cmd.Cmd.preloop |
Cmd.prompt
The prompt issued to solicit input. | python.library.cmd#cmd.Cmd.prompt |
Cmd.ruler
The character used to draw separator lines under the help-message headers. If empty, no ruler line is drawn. It defaults to '='. | python.library.cmd#cmd.Cmd.ruler |
Cmd.undoc_header
The header to issue if the help output has a section for undocumented commands (that is, there are do_*() methods without corresponding help_*() methods). | python.library.cmd#cmd.Cmd.undoc_header |
Cmd.use_rawinput
A flag, defaulting to true. If true, cmdloop() uses input() to display a prompt and read the next command; if false, sys.stdout.write() and sys.stdin.readline() are used. (This means that by importing readline, on systems that support it, the interpreter will automatically support Emacs-like line edi... | python.library.cmd#cmd.Cmd.use_rawinput |
code — Interpreter base classes Source code: Lib/code.py The code module provides facilities to implement read-eval-print loops in Python. Two classes and convenience functions are included which can be used to build applications which provide an interactive interpreter prompt.
class code.InteractiveInterpreter(local... | python.library.code |
code.compile_command(source, filename="<input>", symbol="single")
This function is useful for programs that want to emulate Python’s interpreter main loop (a.k.a. the read-eval-print loop). The tricky part is to determine when the user has entered an incomplete command that can be completed by entering more text (as ... | python.library.code#code.compile_command |
code.interact(banner=None, readfunc=None, local=None, exitmsg=None)
Convenience function to run a read-eval-print loop. This creates a new instance of InteractiveConsole and sets readfunc to be used as the InteractiveConsole.raw_input() method, if provided. If local is provided, it is passed to the InteractiveConsole... | python.library.code#code.interact |
class code.InteractiveConsole(locals=None, filename="<console>")
Closely emulate the behavior of the interactive Python interpreter. This class builds on InteractiveInterpreter and adds prompting using the familiar sys.ps1 and sys.ps2, and input buffering. | python.library.code#code.InteractiveConsole |
InteractiveConsole.interact(banner=None, exitmsg=None)
Closely emulate the interactive Python console. The optional banner argument specify the banner to print before the first interaction; by default it prints a banner similar to the one printed by the standard Python interpreter, followed by the class name of the c... | python.library.code#code.InteractiveConsole.interact |
InteractiveConsole.push(line)
Push a line of source text to the interpreter. The line should not have a trailing newline; it may have internal newlines. The line is appended to a buffer and the interpreter’s runsource() method is called with the concatenated contents of the buffer as source. If this indicates that th... | python.library.code#code.InteractiveConsole.push |
InteractiveConsole.raw_input(prompt="")
Write a prompt and read a line. The returned line does not include the trailing newline. When the user enters the EOF key sequence, EOFError is raised. The base implementation reads from sys.stdin; a subclass may replace this with a different implementation. | python.library.code#code.InteractiveConsole.raw_input |
InteractiveConsole.resetbuffer()
Remove any unhandled source text from the input buffer. | python.library.code#code.InteractiveConsole.resetbuffer |
class code.InteractiveInterpreter(locals=None)
This class deals with parsing and interpreter state (the user’s namespace); it does not deal with input buffering or prompting or input file naming (the filename is always passed in explicitly). The optional locals argument specifies the dictionary in which code will be ... | python.library.code#code.InteractiveInterpreter |
InteractiveInterpreter.runcode(code)
Execute a code object. When an exception occurs, showtraceback() is called to display a traceback. All exceptions are caught except SystemExit, which is allowed to propagate. A note about KeyboardInterrupt: this exception may occur elsewhere in this code, and may not always be cau... | python.library.code#code.InteractiveInterpreter.runcode |
InteractiveInterpreter.runsource(source, filename="<input>", symbol="single")
Compile and run some source in the interpreter. Arguments are the same as for compile_command(); the default for filename is '<input>', and for symbol is 'single'. One of several things can happen: The input is incorrect; compile_command()... | python.library.code#code.InteractiveInterpreter.runsource |
InteractiveInterpreter.showsyntaxerror(filename=None)
Display the syntax error that just occurred. This does not display a stack trace because there isn’t one for syntax errors. If filename is given, it is stuffed into the exception instead of the default filename provided by Python’s parser, because it always uses '... | python.library.code#code.InteractiveInterpreter.showsyntaxerror |
InteractiveInterpreter.showtraceback()
Display the exception that just occurred. We remove the first stack item because it is within the interpreter object implementation. The output is written by the write() method. Changed in version 3.5: The full chained traceback is displayed instead of just the primary tracebac... | python.library.code#code.InteractiveInterpreter.showtraceback |
InteractiveInterpreter.write(data)
Write a string to the standard error stream (sys.stderr). Derived classes should override this to provide the appropriate output handling as needed. | python.library.code#code.InteractiveInterpreter.write |
codecs — Codec registry and base classes Source code: Lib/codecs.py This module defines base classes for standard Python codecs (encoders and decoders) and provides access to the internal Python codec registry, which manages the codec and error handling lookup process. Most standard codecs are text encodings, which enc... | python.library.codecs |
codecs.backslashreplace_errors(exception)
Implements the 'backslashreplace' error handling (for text encodings only): malformed data is replaced by a backslashed escape sequence. | python.library.codecs#codecs.backslashreplace_errors |
