| 25 | ;; Access functions for FIles transferred over SHell protocol from Tramp. | |
| 26 | ||
| 27 | ;; FISH is a protocol developped for the GNU Midnight Commander | |
| 28 | ;; <https://savannah.gnu.org/projects/mc>. A client connects to a | |
| 29 | ;; remote host via ssh (or rsh, shall be configurable), and starts | |
| 30 | ;; there a fish server via the command "start_fish_server". All | |
| 31 | ;; commands from the client have the form "#FISH_COMMAND\n" (always | |
| 32 | ;; one line), followed by equivalent shell commands in case there is | |
| 33 | ;; no fish server running. | |
| 34 | ||
| 35 | ;; The fish server (or the equivalent shell commands) must return the | |
| 36 | ;; response, which is finished by a line "### xxx <optional text>\n". | |
| 37 | ;; "xxx" stands for 3 digits, representing a return code. Return | |
| 38 | ;; codes "# 000" and "# 001" are reserved for fallback implementation | |
| 39 | ;; with native shell commands; they are not used inside the server. See | |
| 40 | ;; <http://cvs.savannah.gnu.org/viewcvs/mc/vfs/README.fish?root=mc&view=markup> | |
| 41 | ;; for details of original specification. | |
| 42 | ||
| 43 | ;; The GNU Midnight Commander implements the original fish protocol | |
| 44 | ;; version 0.0.2. The KDE Konqueror has its own implementation, which | |
| 45 | ;; can be found at | |
| 46 | ;; <http://websvn.kde.org/branches/KDE/3.5/kdebase/kioslave/fish>. It | |
| 47 | ;; implements an extended protocol version 0.0.3. Additionally, it | |
| 48 | ;; provides a fish server implementation in Perl (which is the only | |
| 49 | ;; implementation I've heard of). The following command reference is | |
| 50 | ;; based on that implementation. | |
| 51 | ||
| 52 | ;; All commands return either "### 2xx\n" (OK) or "### 5xx <optional text>\n" | |
| 53 | ;; (NOK). Return codes are mentioned only if they are different from this. | |
| 54 | ;; Spaces in any parameter must be escaped by "\ ". | |
