28 | ||
29 | ;; This package provides remote file editing, similar to ange-ftp. | |
30 | ;; The difference is that ange-ftp uses FTP to transfer files between | |
31 | ;; the local and the remote host, whereas tramp.el uses a combination | |
32 | ;; of rsh and rcp or other work-alike programs, such as ssh/scp. | |
33 | ;; | |

39 | ;; This package only works for Emacs 21.1 and higher, and for XEmacs 21.4 |
40 | ;; and higher. For XEmacs 21, you need the package `fsf-compat' for | |
41 | ;; the `with-timeout' macro.) | |

603 | "*Alist of methods for remote files. |
604 | This is a list of entries of the form (NAME PARAM1 PARAM2 ...). | |
605 | Each NAME stands for a remote access method. Each PARAM is a | |
606 | pair of the form (KEY VALUE). The following KEYs are defined: | |
fb7933a3 KG |
607 | * `tramp-remote-sh' |
608 | This specifies the Bourne shell to use on the remote host. This | |
609 | MUST be a Bourne-like shell. It is normally not necessary to set | |
a4aeb9a4 | 610 | this to any value other than \"/bin/sh\": Tramp wants to use a shell |
fb7933a3 KG |
611 | which groks tilde expansion, but it can search for it. Also note |
612 | that \"/bin/sh\" exists on all Unixen, this might not be true for | |
613 | the value that you decide to use. You Have Been Warned. | |
b25a52cc KG |
614 | * `tramp-login-program' |
615 | This specifies the name of the program to use for logging in to the | |
00d6fd04 MA |
616 | remote host. This may be the name of rsh or a workalike program, |
617 | or the name of telnet or a workalike, or the name of su or a workalike. | |
b25a52cc | 618 | * `tramp-login-args' |
fb7933a3 | 619 | This specifies the list of arguments to pass to the above |
00d6fd04 | 620 | mentioned program. Please note that this is a list of list of arguments, |
fb7933a3 | 621 | that is, normally you don't want to put \"-a -b\" or \"-f foo\" |
00d6fd04 MA |
622 | here. Instead, you want a list (\"-a\" \"-b\"), or (\"-f\" \"foo\"). |
623 | There are some patterns: \"%h\" in this list is replaced by the host | |
624 | name, \"%u\" is replaced by the user name, \"%p\" is replaced by the | |
625 | port number, and \"%%\" can be used to obtain a literal percent character. | |
626 | If a list containing \"%h\", \"%u\" or \"%p\" is unchanged during | |
627 | expansion (i.e. no host or no user specified), this list is not used as | |
628 | argument. By this, arguments like (\"-l\" \"%u\") are optional. | |
629 | \"%t\" is replaced by the temporary file name produced with | |
630 | `tramp-make-tramp-temp-file'. \"%k\" indicates the keep-date | |
631 | parameter of a program, if exists. | |
b25a52cc KG |
632 | * `tramp-copy-program' |
633 | This specifies the name of the program to use for remotely copying | |
634 | the file; this might be the absolute filename of rcp or the name of | |
635 | a workalike program. | |
636 | * `tramp-copy-args' | |
fb7933a3 | 637 | This specifies the list of parameters to pass to the above mentioned |
b25a52cc | 638 | program, the hints for `tramp-login-args' also apply here. |
00d6fd04 MA |
639 | * `tramp-copy-keep-date' |
640 | This specifies whether the copying program when the preserves the | |
641 | timestamp of the original file. | |
642 | * `tramp-default-port' | |
643 | The default port of a method is needed in case of gateway connections. | |
644 | Additionally, it is used as indication which method is prepared for | |
645 | passing gateways. | |
646 | * `tramp-gw-args' | |
647 | As the attribute name says, additional arguments are specified here | |
648 | when a method is applied via a gateway. | |
90f8dc03 KG |
649 | * `tramp-password-end-of-line' |
650 | This specifies the string to use for terminating the line after | |
651 | submitting the password. If this method parameter is nil, then the | |
652 | value of the normal variable `tramp-default-password-end-of-line' | |
653 | is used. This parameter is necessary because the \"plink\" program | |
654 | requires any two characters after sending the password. These do | |
655 | not have to be newline or carriage return characters. Other login | |
656 | programs are happy with just one character, the newline character. | |
657 | We use \"xy\" as the value for methods using \"plink\". | |
b25a52cc KG |
658 | |
659 | What does all this mean? Well, you should specify `tramp-login-program' | |
660 | for all methods; this program is used to log in to the remote site. Then, | |
661 | there are two ways to actually transfer the files between the local and the | |
662 | remote side. One way is using an additional rcp-like program. If you want | |
663 | to do this, set `tramp-copy-program' in the method. | |
fb7933a3 KG |
664 | |
665 | Another possibility for file transfer is inline transfer, i.e. the | |
b25a52cc | 666 | file is passed through the same buffer used by `tramp-login-program'. In |
fb7933a3 | 667 | this case, the file contents need to be protected since the |
b25a52cc | 668 | `tramp-login-program' might use escape codes or the connection might not |
fb7933a3 | 669 | be eight-bit clean. Therefore, file contents are encoded for transit. |
00d6fd04 MA |
670 | See the variables `tramp-local-coding-commands' and |
671 | `tramp-remote-coding-commands' for details. | |
fb7933a3 | 672 | |
16674e4f | 673 | So, to summarize: if the method is an out-of-band method, then you |
b25a52cc | 674 | must specify `tramp-copy-program' and `tramp-copy-args'. If it is an |
00d6fd04 MA |
675 | inline method, then these two parameters should be nil. Methods which |
676 | are fit for gateways must have `tramp-default-port' at least. | |
fb7933a3 KG |
677 | |
678 | Notes: | |
679 | ||
00d6fd04 MA |
680 | When using `su' or `sudo' the phrase `open connection to a remote |
681 | host' sounds strange, but it is used nevertheless, for consistency. | |
682 | No connection is opened to a remote host, but `su' or `sudo' is | |
683 | started on the local host. You should specify a remote host | |
684 | `localhost' or the name of the local host. Another host name is | |
685 | useful only in combination with `tramp-default-proxies-alist'.") | |

1476 | It is necessary only on systems which have a buggy `process-send-string' | |
1477 | implementation. The necessity, whether this variable must be set, can be | |
1478 | checked via the following code: | |

1487 | (let ((proc (start-process (buffer-name) (current-buffer) | |
1488 | \"ssh\" \"-l\" user host \"wc\" \"-c\"))) | |
1489 | (when (memq (process-status proc) '(run open)) | |
1490 | (process-send-string proc (make-string sent ?\\ )) | |
1491 | (process-send-eof proc) | |

1507 | ||
1508 | In the Emacs normally running Tramp, evaluate the above code | |
55880756 | 1509 | \(replace \"xxx\" and \"yyy\" by the remote user and host name, |
11948172 MA |
1510 | respectively). You can do this, for example, by pasting it into |
1511 | the `*scratch*' buffer and then hitting C-j with the cursor after the | |
1512 | last closing parenthesis. Note that it works only if you have configured | |
1513 | \"ssh\" to run without password query, see ssh-agent(1). | |
1514 | ||
1515 | You will see the number of bytes sent successfully to the remote host. | |
1516 | If that number exceeds 1000, you can stop the execution by hitting | |
1517 | C-g, because your Emacs is likely clean. | |
1518 | ||
11948172 MA |
1519 | When it is necessary to set `tramp-chunksize', you might consider to |
1520 | use an out-of-the-band method (like \"scp\") instead of an internal one | |
55880756 | 1521 | \(like \"ssh\"), because setting `tramp-chunksize' to non-nil decreases |
11948172 | 1522 | performance. |
c951aecb | 1523 | |
00d6fd04 MA |
1524 | If your Emacs is buggy, the code stops and gives you an indication |
1525 | about the value `tramp-chunksize' should be set. Maybe you could just | |
1526 | experiment a bit, e.g. changing the values of `init' and `step' | |
1527 | in the third line of the code. | |

7876 | ;; Currently (as of Emacs 20.5), the function `shell-quote-argument' | |
7877 | ;; does not deal well with newline characters. Newline is replaced by | |
7878 | ;; backslash newline. But if, say, the string `a backslash newline b' | |
7879 | ;; is passed to a shell, the shell will expand this into "ab", | |
7880 | ;; completely omitting the newline. This is not what was intended. | |
7881 | ;; It does not appear to be possible to make the function | |
7882 | ;; `shell-quote-argument' work with newlines without making it | |
7883 | ;; dependent on the shell used. But within this package, we know that | |
7884 | ;; we will always use a Bourne-like shell, so we use an approach which | |
7885 | ;; groks newlines. | |
7886 | ;; | |
7887 | ;; The approach is simple: we call `shell-quote-argument', then | |
7888 | ;; massage the newline part of the result. | |
7889 | ;; | |
7890 | ;; This function should produce a string which is grokked by a Unix | |
7891 | ;; shell, even if the Emacs is running on Windows. Since this is the | |
7892 | ;; kludges section, we bind `system-type' in such a way that | |
7893 | ;; `shell-quote-arguments' behaves as if on Unix. | |
7894 | ;; | |

7896 | ;; function to work with Bourne-like shells. | |
