26 | ;;; Commentary: | |
27 | ||
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 | ;; | |

182 | Each NAME stands for a remote access method. Each PARAM is a | |
183 | pair of the form (KEY VALUE). The following KEYs are defined: | |
fb7933a3 KG |
184 | * `tramp-remote-sh' |
185 | This specifies the Bourne shell to use on the remote host. This | |
186 | MUST be a Bourne-like shell. It is normally not necessary to set | |
a4aeb9a4 | 187 | this to any value other than \"/bin/sh\": Tramp wants to use a shell |
fb7933a3 KG |
188 | which groks tilde expansion, but it can search for it. Also note |
189 | that \"/bin/sh\" exists on all Unixen, this might not be true for | |
190 | the value that you decide to use. You Have Been Warned. | |
b25a52cc KG |
191 | * `tramp-login-program' |
192 | This specifies the name of the program to use for logging in to the | |
00d6fd04 MA |
193 | remote host. This may be the name of rsh or a workalike program, |
194 | or the name of telnet or a workalike, or the name of su or a workalike. | |
b25a52cc | 195 | * `tramp-login-args' |
fb7933a3 | 196 | This specifies the list of arguments to pass to the above |
00d6fd04 | 197 | mentioned program. Please note that this is a list of list of arguments, |
fb7933a3 | 198 | that is, normally you don't want to put \"-a -b\" or \"-f foo\" |
00d6fd04 MA |
199 | here. Instead, you want a list (\"-a\" \"-b\"), or (\"-f\" \"foo\"). |
200 | There are some patterns: \"%h\" in this list is replaced by the host | |
201 | name, \"%u\" is replaced by the user name, \"%p\" is replaced by the | |
202 | port number, and \"%%\" can be used to obtain a literal percent character. | |
203 | If a list containing \"%h\", \"%u\" or \"%p\" is unchanged during | |
204 | expansion (i.e. no host or no user specified), this list is not used as | |
205 | argument. By this, arguments like (\"-l\" \"%u\") are optional. | |
206 | \"%t\" is replaced by the temporary file name produced with | |
207 | `tramp-make-tramp-temp-file'. \"%k\" indicates the keep-date | |
208 | parameter of a program, if exists. | |
a7723e05 MA |
209 | * `tramp-async-args' |
210 | When an asynchronous process is started, we know already that | |
211 | the connection works. Therefore, we can pass additional | |
212 | parameters to suppress diagnostic messages, in order not to | |
213 | tamper the process output. | |
b25a52cc KG |
214 | * `tramp-copy-program' |
215 | This specifies the name of the program to use for remotely copying | |
216 | the file; this might be the absolute filename of rcp or the name of | |
217 | a workalike program. | |
218 | * `tramp-copy-args' | |
fb7933a3 | 219 | This specifies the list of parameters to pass to the above mentioned |
b25a52cc | 220 | program, the hints for `tramp-login-args' also apply here. |
00d6fd04 MA |
221 | * `tramp-copy-keep-date' |
222 | This specifies whether the copying program when the preserves the | |
223 | timestamp of the original file. | |
b88f2d0a MA |
224 | * `tramp-copy-keep-tmpfile' |
225 | This specifies whether a temporary local file shall be kept | |
226 | for optimization reasons (useful for \"rsync\" methods). | |
227 | * `tramp-copy-recursive' | |
228 | Whether the operation copies directories recursively. | |
00d6fd04 MA |
229 | * `tramp-default-port' |
230 | The default port of a method is needed in case of gateway connections. | |
231 | Additionally, it is used as indication which method is prepared for | |
232 | passing gateways. | |
233 | * `tramp-gw-args' | |
234 | As the attribute name says, additional arguments are specified here | |
235 | when a method is applied via a gateway. | |
90f8dc03 KG |
236 | * `tramp-password-end-of-line' |
237 | This specifies the string to use for terminating the line after | |
238 | submitting the password. If this method parameter is nil, then the | |
239 | value of the normal variable `tramp-default-password-end-of-line' | |
240 | is used. This parameter is necessary because the \"plink\" program | |
241 | requires any two characters after sending the password. These do | |
242 | not have to be newline or carriage return characters. Other login | |
243 | programs are happy with just one character, the newline character. | |
244 | We use \"xy\" as the value for methods using \"plink\". | |
b25a52cc KG |
245 | |
246 | What does all this mean? Well, you should specify `tramp-login-program' | |
247 | for all methods; this program is used to log in to the remote site. Then, | |
248 | there are two ways to actually transfer the files between the local and the | |
249 | remote side. One way is using an additional rcp-like program. If you want | |
250 | to do this, set `tramp-copy-program' in the method. | |
fb7933a3 KG |
251 | |
252 | Another possibility for file transfer is inline transfer, i.e. the | |
b25a52cc | 253 | file is passed through the same buffer used by `tramp-login-program'. In |
fb7933a3 | 254 | this case, the file contents need to be protected since the |
b25a52cc | 255 | `tramp-login-program' might use escape codes or the connection might not |
fb7933a3 | 256 | be eight-bit clean. Therefore, file contents are encoded for transit. |
00d6fd04 MA |
257 | See the variables `tramp-local-coding-commands' and |
258 | `tramp-remote-coding-commands' for details. | |
fb7933a3 | 259 | |
16674e4f | 260 | So, to summarize: if the method is an out-of-band method, then you |
b25a52cc | 261 | must specify `tramp-copy-program' and `tramp-copy-args'. If it is an |
00d6fd04 MA |
262 | inline method, then these two parameters should be nil. Methods which |
263 | are fit for gateways must have `tramp-default-port' at least. | |
fb7933a3 KG |
264 | |
265 | Notes: | |
266 | ||
00d6fd04 MA |
267 | When using `su' or `sudo' the phrase `open connection to a remote |
268 | host' sounds strange, but it is used nevertheless, for consistency. | |
269 | No connection is opened to a remote host, but `su' or `sudo' is | |
270 | started on the local host. You should specify a remote host | |
271 | `localhost' or the name of the local host. Another host name is | |
272 | useful only in combination with `tramp-default-proxies-alist'.") | |

946 | the `*scratch*' buffer and then hitting C-j with the cursor after the |

950 | You will see the number of bytes sent successfully to the remote host. | |

3653 | ;; * In Emacs 21, `insert-directory' shows total number of bytes used |
3654 | ;; by the files in that directory. Add this here. | |
3655 | ;; * Avoid screen blanking when hitting `g' in dired. (Eli Tziperman) | |

fb7933a3 | 3657 | ;; * abbreviate-file-name |
8e754ea2 | 3658 | ;; * Better error checking. At least whenever we see something |

00d6fd04 | 3665 | ;; * Make `tramp-default-user' obsolete. |
3e2fa353 MA |
3666 | ;; * Implement a general server-local-variable mechanism, as there are |
3667 | ;; probably other variables that need different values for different | |
3668 | ;; servers too. The user could then configure a variable (such as | |
3669 | ;; tramp-server-local-variable-alist) to define any such variables | |
3670 | ;; that they need to, which would then be let bound as appropriate | |
6e4f5731 | 3671 | ;; in tramp functions. (Jason Rumney) |

3672 | ;; * IMHO, it's a drawback that currently Tramp doesn't support |
3673 | ;; Unicode in Dired file names by default. Is it possible to | |
3674 | ;; improve Tramp to set LC_ALL to "C" only for commands where Tramp | |
3675 | ;; expects English? Or just to set LC_MESSAGES to "C" if Tramp | |
6e4f5731 | 3676 | ;; expects only English messages? (Juri Linkov) |

44ffae96 MA |
3678 | ;; * I was wondering it it would be possible to use tramp even if I'm |
3679 | ;; actually using sshfs. But when I launch a command I would like | |
3680 | ;; to get it executed on the remote machine where the files really | |
3681 | ;; are. (Andrea Crotti) | |
