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

38 | ;; This package only works for Emacs 20 and higher, and for XEmacs 21 |
39 | ;; and higher. (XEmacs 20 is missing the `with-timeout' macro. Emacs | |
40 | ;; 19 is reported to have other problems. For XEmacs 21, you need the | |
41 | ;; package `fsf-compat' for the `with-timeout' macro.) | |
42 | ;; | |
43 | ;; This version might not work with pre-Emacs 21 VC unless VC is | |
44 | ;; loaded before tramp.el. Could you please test this and tell me about | |
45 | ;; the result? Thanks. | |

429 | "*Alist of methods for remote files. | |
430 | This is a list of entries of the form (NAME PARAM1 PARAM2 ...). | |
431 | Each NAME stands for a remote access method. Each PARAM is a | |
432 | pair of the form (KEY VALUE). The following KEYs are defined: | |
16674e4f | 433 | * `tramp-connection-function' |
fb7933a3 KG |
434 | This specifies the function to use to connect to the remote host. |
435 | Currently, `tramp-open-connection-rsh', `tramp-open-connection-telnet' | |
436 | and `tramp-open-connection-su' are defined. See the documentation | |
437 | of these functions for more details. | |
438 | * `tramp-remote-sh' | |
439 | This specifies the Bourne shell to use on the remote host. This | |
440 | MUST be a Bourne-like shell. It is normally not necessary to set | |
441 | this to any value other than \"/bin/sh\": tramp wants to use a shell | |
442 | which groks tilde expansion, but it can search for it. Also note | |
443 | that \"/bin/sh\" exists on all Unixen, this might not be true for | |
444 | the value that you decide to use. You Have Been Warned. | |
b25a52cc KG |
445 | * `tramp-login-program' |
446 | This specifies the name of the program to use for logging in to the | |
447 | remote host. Depending on `tramp-connection-function', this may be | |
448 | the name of rsh or a workalike program (when | |
449 | `tramp-connection-function' is `tramp-open-connection-rsh'), or the | |
450 | name of telnet or a workalike (for `tramp-open-connection-telnet'), | |
451 | or the name of su or a workalike (for `tramp-open-connection-su'). | |
452 | * `tramp-login-args' | |
fb7933a3 KG |
453 | This specifies the list of arguments to pass to the above |
454 | mentioned program. Please note that this is a list of arguments, | |
455 | that is, normally you don't want to put \"-a -b\" or \"-f foo\" | |
456 | here. Instead, you want two list elements, one for \"-a\" and one | |
457 | for \"-b\", or one for \"-f\" and one for \"foo\". | |
b25a52cc KG |
458 | If `tramp-connection-function' is `tramp-open-connection-su', then |
459 | \"%u\" in this list is replaced by the user name, and \"%%\" can | |
460 | be used to obtain a literal percent character. | |
461 | * `tramp-copy-program' | |
462 | This specifies the name of the program to use for remotely copying | |
463 | the file; this might be the absolute filename of rcp or the name of | |
464 | a workalike program. | |
465 | * `tramp-copy-args' | |
fb7933a3 | 466 | This specifies the list of parameters to pass to the above mentioned |
b25a52cc KG |
467 | program, the hints for `tramp-login-args' also apply here. |
468 | * `tramp-copy-keep-date-arg' | |
469 | This specifies the parameter to use for the copying program when the | |
470 | timestamp of the original file should be kept. For `rcp', use `-p', for | |
fb7933a3 | 471 | `rsync', use `-t'. |
b25a52cc KG |
472 | |
473 | What does all this mean? Well, you should specify `tramp-login-program' | |
474 | for all methods; this program is used to log in to the remote site. Then, | |
475 | there are two ways to actually transfer the files between the local and the | |
476 | remote side. One way is using an additional rcp-like program. If you want | |
477 | to do this, set `tramp-copy-program' in the method. | |
fb7933a3 KG |
478 | |
479 | Another possibility for file transfer is inline transfer, i.e. the | |
b25a52cc | 480 | file is passed through the same buffer used by `tramp-login-program'. In |
fb7933a3 | 481 | this case, the file contents need to be protected since the |
b25a52cc | 482 | `tramp-login-program' might use escape codes or the connection might not |
fb7933a3 | 483 | be eight-bit clean. Therefore, file contents are encoded for transit. |
16674e4f | 484 | See the variable `tramp-coding-commands' for details. |
fb7933a3 | 485 | |
16674e4f | 486 | So, to summarize: if the method is an out-of-band method, then you |
b25a52cc | 487 | must specify `tramp-copy-program' and `tramp-copy-args'. If it is an |
16674e4f KG |
488 | inline method, then these two parameters should be nil. Every method, |
489 | inline or out of band, must specify `tramp-connection-function' plus | |
b25a52cc | 490 | the associated arguments (for example, the login program if you chose |
fb7933a3 KG |
491 | `tramp-open-connection-telnet'). |
492 | ||
493 | Notes: | |
494 | ||
495 | When using `tramp-open-connection-su' the phrase `open connection to a | |
496 | remote host' sounds strange, but it is used nevertheless, for | |
497 | consistency. No connection is opened to a remote host, but `su' is | |
498 | started on the local host. You are not allowed to specify a remote | |
16674e4f | 499 | host other than `localhost' or the name of the local host." |

6335 | ;; putting the port number into the filename for ssh and ftp | |
6336 | ;; files. This could be subsumed by the new mechanism as well. | |

6342 | ;; if the remote end doesn't support mimencode or a similar program. | |
6343 | ;; For reading files from the remote host, we can just parse the output | |
6344 | ;; of `od -b'. For writing files to the remote host, we construct | |
6345 | ;; a shell program which contains only "safe" ascii characters | |
6346 | ;; and which writes the right bytes to the file. We can use printf(1) | |
6347 | ;; or "echo -e" or the printf function in awk and use octal escapes | |
6348 | ;; for the "dangerous" characters. The null byte might be a problem. | |
6349 | ;; On some systems, the octal escape doesn't work. So we try the following | |
6350 | ;; two commands to write a null byte: | |
