| 2 Alternatives to cmd and cmd2 | |
| 3 ============================ | |

| 5 For programs that do not interact with the user in a continuous loop - | |
| 6 programs that simply accept a set of arguments from the command line, return | |
| 7 results, and do not keep the user within the program's environment - all | |
| 8 you need are sys_\ .argv (the command-line arguments) and optparse_ | |
| 9 (for parsing UNIX-style options and flags). | |
| 10 | |
| 11 .. _optparse: http://docs.python.org/library/optparse.html#module-optparse | |
| 12 | |
| 13 .. _sys: http://docs.python.org/library/sys.html#module-sys | |
| 14 | |
| 15 .. _curses: http://docs.python.org/library/curses.html#module-curses | |
| 16 | |
| 17 .. _cmd: http://docs.python.org/library/cmd.html#module-cmd | |
| 18 | |
| 19 The curses_ module produces applications that interact via a plaintext | |
| 20 terminal window, but are not limited to simple text input and output; | |
| 21 they can paint the screen with options that are selected from using the | |
| 22 cursor keys. However, programming a curses_-based application is not as | |
| 23 straightforward as using cmd_. | |
| 24 | |
| 25 Several packages in PyPI enable interactive command-line applications | |
| 26 approximately similar in concept to cmd_ applications. None of them | |
| 27 share cmd2's close ties to cmd, but they may be worth investigating | |
| 28 nonetheless. | |
| 29 | |
| 30 * CmdLoop_ | |
| 31 * cly_ | |
| 32 * CmDO_ (As of Feb. 2010, webpage is missing.) | |
| 33 * pycopia-CLI_ | |
| 34 | |
| 35 cmdln_, another package in PyPI, is an extension to cmd_ and, though it | |
| 36 doesn't retain full cmd_ compatibility, shares its basic structure with | |
| 37 cmd_. | |
| 38 | |
| 39 .. _cmdln_ http://pypi.python.org/pypi/cmdln | |
| 40 | |
| 41 .. _CmdLoop: http://pypi.python.org/pypi/CmdLoop | |
| 42 | |
| 43 .. _cly: http://pypi.python.org/pypi/cly | |
| 44 | |
| 45 .. _CmDO: http://pypi.python.org/pypi/CmDO/0.7 | |
| 46 | |
| 47 .. _pycopia-CLI: http://pypi.python.org/pypi/pycopia-CLI/1.0 | |
| 48 | |
| 49 I've found several alternatives to cmd in the Cheese Shop - CmdLoop, cly, CMdO, and pycopia. cly looks wonderful, but I haven't been able to get it working under Windows, and that's a show-stopper for many potential sqlpython users. In any case, none of the alternatives are based on cmd - they're written from scratch, which means that a cmd-based app would need complete rewriting to use them. I like sticking close to the Standard Library whenever possible. cmd2 lets you do that. | |
