30 | ;; This package provides remote file editing, similar to ange-ftp. | |
31 | ;; The difference is that ange-ftp uses FTP to transfer files between | |
32 | ;; the local and the remote host, whereas tramp.el uses a combination | |
33 | ;; of rsh and rcp or other work-alike programs, such as ssh/scp. | |
34 | ;; | |

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

538 | "*Alist of methods for remote files. | |
539 | This is a list of entries of the form (NAME PARAM1 PARAM2 ...). | |
540 | Each NAME stands for a remote access method. Each PARAM is a | |
541 | pair of the form (KEY VALUE). The following KEYs are defined: | |
16674e4f | 542 | * `tramp-connection-function' |
fb7933a3 KG |
543 | This specifies the function to use to connect to the remote host. |
544 | Currently, `tramp-open-connection-rsh', `tramp-open-connection-telnet' | |
545 | and `tramp-open-connection-su' are defined. See the documentation | |
546 | of these functions for more details. | |
547 | * `tramp-remote-sh' | |
548 | This specifies the Bourne shell to use on the remote host. This | |
549 | MUST be a Bourne-like shell. It is normally not necessary to set | |
550 | this to any value other than \"/bin/sh\": tramp wants to use a shell | |
551 | which groks tilde expansion, but it can search for it. Also note | |
552 | that \"/bin/sh\" exists on all Unixen, this might not be true for | |
553 | the value that you decide to use. You Have Been Warned. | |
b25a52cc KG |
554 | * `tramp-login-program' |
555 | This specifies the name of the program to use for logging in to the | |
556 | remote host. Depending on `tramp-connection-function', this may be | |
557 | the name of rsh or a workalike program (when | |
558 | `tramp-connection-function' is `tramp-open-connection-rsh'), or the | |
559 | name of telnet or a workalike (for `tramp-open-connection-telnet'), | |
560 | or the name of su or a workalike (for `tramp-open-connection-su'). | |
561 | * `tramp-login-args' | |
fb7933a3 KG |
562 | This specifies the list of arguments to pass to the above |
563 | mentioned program. Please note that this is a list of arguments, | |
564 | that is, normally you don't want to put \"-a -b\" or \"-f foo\" | |
565 | here. Instead, you want two list elements, one for \"-a\" and one | |
566 | for \"-b\", or one for \"-f\" and one for \"foo\". | |
b25a52cc KG |
567 | If `tramp-connection-function' is `tramp-open-connection-su', then |
568 | \"%u\" in this list is replaced by the user name, and \"%%\" can | |
569 | be used to obtain a literal percent character. | |
570 | * `tramp-copy-program' | |
571 | This specifies the name of the program to use for remotely copying | |
572 | the file; this might be the absolute filename of rcp or the name of | |
573 | a workalike program. | |
574 | * `tramp-copy-args' | |
fb7933a3 | 575 | This specifies the list of parameters to pass to the above mentioned |
b25a52cc KG |
576 | program, the hints for `tramp-login-args' also apply here. |
577 | * `tramp-copy-keep-date-arg' | |
578 | This specifies the parameter to use for the copying program when the | |
579 | timestamp of the original file should be kept. For `rcp', use `-p', for | |
fb7933a3 | 580 | `rsync', use `-t'. |
90f8dc03 KG |
581 | * `tramp-password-end-of-line' |
582 | This specifies the string to use for terminating the line after | |
583 | submitting the password. If this method parameter is nil, then the | |
584 | value of the normal variable `tramp-default-password-end-of-line' | |
585 | is used. This parameter is necessary because the \"plink\" program | |
586 | requires any two characters after sending the password. These do | |
587 | not have to be newline or carriage return characters. Other login | |
588 | programs are happy with just one character, the newline character. | |
589 | We use \"xy\" as the value for methods using \"plink\". | |
b25a52cc KG |
590 | |
591 | What does all this mean? Well, you should specify `tramp-login-program' | |
592 | for all methods; this program is used to log in to the remote site. Then, | |
593 | there are two ways to actually transfer the files between the local and the | |
594 | remote side. One way is using an additional rcp-like program. If you want | |
595 | to do this, set `tramp-copy-program' in the method. | |
fb7933a3 KG |
596 | |
597 | Another possibility for file transfer is inline transfer, i.e. the | |
b25a52cc | 598 | file is passed through the same buffer used by `tramp-login-program'. In |
fb7933a3 | 599 | this case, the file contents need to be protected since the |
b25a52cc | 600 | `tramp-login-program' might use escape codes or the connection might not |
fb7933a3 | 601 | be eight-bit clean. Therefore, file contents are encoded for transit. |
16674e4f | 602 | See the variable `tramp-coding-commands' for details. |
fb7933a3 | 603 | |
16674e4f | 604 | So, to summarize: if the method is an out-of-band method, then you |
b25a52cc | 605 | must specify `tramp-copy-program' and `tramp-copy-args'. If it is an |
16674e4f KG |
606 | inline method, then these two parameters should be nil. Every method, |
607 | inline or out of band, must specify `tramp-connection-function' plus | |
b25a52cc | 608 | the associated arguments (for example, the login program if you chose |
fb7933a3 KG |
609 | `tramp-open-connection-telnet'). |
610 | ||
611 | Notes: | |
612 | ||
613 | When using `tramp-open-connection-su' the phrase `open connection to a | |
614 | remote host' sounds strange, but it is used nevertheless, for | |
615 | consistency. No connection is opened to a remote host, but `su' is | |
616 | started on the local host. You are not allowed to specify a remote | |
16674e4f | 617 | host other than `localhost' or the name of the local host." |

1438 | experiment a bit, e.g. changing the values of `init' and `step' | |
1439 | in the third line of the code. | |
1440 | ||
1441 | When it is necessary to set `tramp-chunksize', you might consider to | |
1442 | use an out-of-the-band method (like \"scp\") instead of an internal one | |

7274 | ;; Currently (as of Emacs 20.5), the function `shell-quote-argument' | |
7275 | ;; does not deal well with newline characters. Newline is replaced by | |
7276 | ;; backslash newline. But if, say, the string `a backslash newline b' | |
7277 | ;; is passed to a shell, the shell will expand this into "ab", | |
7278 | ;; completely omitting the newline. This is not what was intended. | |
7279 | ;; It does not appear to be possible to make the function | |
7280 | ;; `shell-quote-argument' work with newlines without making it | |
7281 | ;; dependent on the shell used. But within this package, we know that | |
7282 | ;; we will always use a Bourne-like shell, so we use an approach which | |
7283 | ;; groks newlines. | |
7284 | ;; | |
7285 | ;; The approach is simple: we call `shell-quote-argument', then | |
7286 | ;; massage the newline part of the result. | |
7287 | ;; | |
7288 | ;; This function should produce a string which is grokked by a Unix | |
7289 | ;; shell, even if the Emacs is running on Windows. Since this is the | |
7290 | ;; kludges section, we bind `system-type' in such a way that | |
7291 | ;; `shell-quote-arguments' behaves as if on Unix. | |

7621 | ;; * Allow putting passwords in the filename. |
7622 | ;; This should be implemented via a general mechanism to add | |
7623 | ;; parameters in filenames. There is currently a kludge for | |
7624 | ;; putting the port number into the filename for ssh and ftp | |
7625 | ;; files. This could be subsumed by the new mechanism as well. | |
7626 | ;; Another approach is to read a netrc file like ~/.authinfo | |
7627 | ;; from Gnus. | |
7628 | ;; * Handle nonlocal exits such as C-g. | |
16674e4f | 7629 | ;; * Autodetect if remote `ls' groks the "--dired" switch. |
b1d06e75 KG |
7630 | ;; * Add fallback for inline encodings. This should be used |
7631 | ;; if the remote end doesn't support mimencode or a similar program. | |
7632 | ;; For reading files from the remote host, we can just parse the output | |
7633 | ;; of `od -b'. For writing files to the remote host, we construct | |
7634 | ;; a shell program which contains only "safe" ascii characters | |
7635 | ;; and which writes the right bytes to the file. We can use printf(1) | |
7636 | ;; or "echo -e" or the printf function in awk and use octal escapes | |
7637 | ;; for the "dangerous" characters. The null byte might be a problem. | |
7638 | ;; On some systems, the octal escape doesn't work. So we try the following | |
7639 | ;; two commands to write a null byte: | |
7640 | ;; dd if=/dev/zero bs=1 count=1 | |
7641 | ;; echo | tr '\n' '\000' | |
16674e4f KG |
7642 | ;; * Separate local `tramp-coding-commands' from remote ones. Connect |
7643 | ;; the two via a format which can be `uu' or `b64'. Then we can search | |
7644 | ;; for the right local commands and the right remote commands separately. | |
fb7933a3 KG |
7645 | ;; * Cooperate with PCL-CVS. It uses start-process, which doesn't |
7646 | ;; work for remote files. | |
fb7933a3 | 7647 | ;; * Rewrite `tramp-shell-quote-argument' to abstain from using |
b1d06e75 | 7648 | ;; `shell-quote-argument'. |
fb7933a3 | 7649 | ;; * Completion gets confused when you leave out the method name. |
fb7933a3 KG |
7650 | ;; * In Emacs 21, `insert-directory' shows total number of bytes used |
7651 | ;; by the files in that directory. Add this here. | |
7652 | ;; * Avoid screen blanking when hitting `g' in dired. (Eli Tziperman) | |
7653 | ;; * Make ffap.el grok Tramp filenames. (Eli Tziperman) | |
7654 | ;; * When logging in, keep looking for questions according to an alist | |
7655 | ;; and then invoke the right function. | |
7656 | ;; * Case-insensitive filename completion. (Norbert Goevert.) | |
7657 | ;; * Running CVS remotely doesn't appear to work right. It thinks | |
7658 | ;; files are locked by somebody else even if I'm the locking user. | |
7659 | ;; Sometimes, one gets `No CVSROOT specified' errors from CVS. | |
7660 | ;; (Skip Montanaro) | |
7661 | ;; * Don't use globbing for directories with many files, as this is | |
7662 | ;; likely to produce long command lines, and some shells choke on | |
7663 | ;; long command lines. | |
fb7933a3 KG |
7664 | ;; * Find out about the new auto-save mechanism in Emacs 21 and |
7665 | ;; do the right thing. | |
7666 | ;; * `vc-directory' does not work. It never displays any files, even | |
7667 | ;; if it does show files when run locally. | |
7668 | ;; * Allow correction of passwords, if the remote end allows this. | |
7669 | ;; (Mark Hershberger) | |
fb7933a3 KG |
7670 | ;; * How to deal with MULE in `insert-file-contents' and `write-region'? |
7671 | ;; * Do asynchronous `shell-command's. | |
7672 | ;; * Grok `append' parameter for `write-region'. | |
7673 | ;; * Test remote ksh or bash for tilde expansion in `tramp-find-shell'? | |
7674 | ;; * abbreviate-file-name | |
7675 | ;; * grok ~ in tramp-remote-path (Henrik Holm <henrikh@tele.ntnu.no>) | |
fb7933a3 KG |
7676 | ;; * Also allow to omit user names when doing multi-hop. Not sure yet |
7677 | ;; what the user names should default to, though. | |
7678 | ;; * better error checking. At least whenever we see something | |
7679 | ;; strange when doing zerop, we should kill the process and start | |
7680 | ;; again. (Greg Stark) | |
7681 | ;; * Add caching for filename completion. (Greg Stark) | |
bf247b6e | 7682 | ;; Of course, this has issues with usability (stale cache bites) |
fb7933a3 KG |
7683 | ;; -- <daniel@danann.net> |
7684 | ;; * Provide a local cache of old versions of remote files for the rsync | |
7685 | ;; transfer method to use. (Greg Stark) | |
7686 | ;; * Remove unneeded parameters from methods. | |
7687 | ;; * Invoke rsync once for copying a whole directory hierarchy. | |

fb7933a3 KG |
7692 | ;; * Make it work for different encodings, and for different file name |
7693 | ;; encodings, too. (Daniel Pittman) | |
7694 | ;; * Change applicable functions to pass a struct tramp-file-name rather | |
7432277c | 7695 | ;; than the individual items MULTI-METHOD, METHOD, USER, HOST, LOCALNAME. |
fb7933a3 KG |
7696 | ;; * Implement asynchronous shell commands. |
7697 | ;; * Clean up unused *tramp/foo* buffers after a while. (Pete Forman) | |
7698 | ;; * Progress reports while copying files. (Michael Kifer) | |
7699 | ;; * `Smart' connection method that uses inline for small and out of | |
7700 | ;; band for large files. (Michael Kifer) | |
7701 | ;; * Don't search for perl5 and perl. Instead, only search for perl and | |
7702 | ;; then look if it's the right version (with `perl -v'). | |
7703 | ;; * When editing a remote CVS controlled file as a different user, VC | |
7704 | ;; gets confused about the file locking status. Try to find out why | |
7705 | ;; the workaround doesn't work. | |
fb7933a3 KG |
7706 | ;; * Change `copy-file' to grok the case where the filename handler |
7707 | ;; for the source and the target file are different. Right now, | |
7708 | ;; it looks at the source file and then calls that handler, if | |
7709 | ;; there is one. But since ange-ftp, for instance, does not know | |
7710 | ;; about Tramp, it does not do the right thing if the target file | |
7711 | ;; name is a Tramp name. | |
3cdaec13 | 7712 | ;; * Username and hostname completion. |

7713 | ;; ** If `partial-completion-mode' isn't loaded, "/foo:bla" tries to |

16674e4f | 7716 | ;; ** Try to avoid usage of `last-input-event' in `tramp-completion-mode'. |
