-
- The `term' package includes the major modes `term', `shell', and
-`gud' (for running gbd or another debugger). It is a replacement for
-the comint mode of Emacs 19, as well as shell, gdb, terminal, and
-telnet modes. The package works best with recent releases of Emacs 19,
-but will also work reasonably well with Emacs 18 as well as Lucid Emacs
-19.
-
- The file `nshell.el' is a wrapper to use unless term mode is built
-into Emacs. If works around some of the missing in older Emacs
-versions. To use it, edit the paths in `nshell.el', appropriately, and
-then `M-x load-file nshell.el RET'. This will also load in replacement
-shell and gud modes.

-Overview
-========
-
- The `term' mode is used to control a program (an "inferior process").
-It sends most keyboard input characters to the program, and displays
-output from the program in the buffer. This is similar to the
-traditional comint mode, and modes derived from it (such as shell and
-gdb modes). You can do with the new term-based shell the same sort of
-things you could do with the old shell mode, using more or less the
-same interface. However, the new mode is more flexible, and works
-somewhat differently.

-
-Output from the inferior
-------------------------
-
- In typical usage, output from the inferior is added to the end of
-the buffer. If needed, the window will be scrolled, just like a
-regular terminal. (Only one line at a time will be scrolled, just like
-regular terminals, and in contrast to the old shell mode.) Thus the
-buffer becomes a log of your interaction with the inferior, just like
-the old shell mode.
-
- Like a real terminal, term maintains a "cursor position." This is
-the `process-mark' of the inferior process. If the process-mark is not
-at the end of the buffer, output from the inferior will overwrite
-existing text in the buffer. This is like a real terminal, but unlike
-the old shell mode (which inserts the output, instead of overwriting).
-
- Some programs (such as Emacs itself) need to control the appearance
-on the screen in detail. They do this by sending special control
-codes. The exact control codes needed from terminal to terminal, but
-nowadays most terminals and terminal emulators (including xterm)
-understand the so-called "ANSI escape sequences" (first popularized by
-the Digital's VT100 family of terminal). The term mode also
-understands these escape sequences, and for each control code does the
-appropriate thing to change the buffer so that the appearance of the
-window will match what it would be on a real terminal. (In contrast,
-the old shell mode doesn't handle terminal control codes at all.)
-
- See <...> for the specific control codes.

-
-The sub-buffer
---------------
-
- A program that talks to terminal expects the terminal to have a
-fixed size. If the program is talking a terminal emulator program such
-as `xterm', that size can be changed (if the xterm window is re-sized),
-but programs still assume a logical terminal that has a fixed size
-independent of the amount of output transmitted by the programs.
-
- To programs that use it, the Emacs terminal emulator acts as if it
-too has a fixed size. The "sub-buffer" is the part of a `term'-mode
-buffer that corresponds to a "normal" terminal. Most of the time
-(unless you explicitly scroll the window displaying the buffer), the
-sub-buffer is the part of the buffer that is displayed in a window.
-
- The sub-buffer is defined in terms of three buffer-local-variable:
-
- - Variable: term-height
- The height of the sub-buffer, in screen lines.
-
- - Variable: term-width
- The width of the sub-buffer, in screen columns.
-
- - Variable: term-home-marker
- The "home" position, that is the top left corner of the sub-buffer.
-
- The sub-buffer is assumed to be the end part of the buffer; the
-`term-home-marker' should never be more than `term-height' screen lines
-from the end of the buffer.
-
-\1f
-File: term.info, Node: altsubbuffer, Next: Input to the inferior, Prev: subbuffer, Up: Overview
-
-The alternate sub-buffer
-------------------------
-
- When a "graphical" program finishes, it is nice to restore the
-screen state to what it was before the program started. Many people
-are used to this behavior from `xterm', and its also offered by the
-`term' emulator.
-
- - Function: term-switch-to-alternate-sub-buffer SET
- If SET is true, and we're not already using the alternate
- sub-buffer, switch to it. What this means is that the
- `term-home-marker' is saved (in the variable
- `term-saved-home-marker'), and the `term-home-marker' is set to
- the end of the buffer.
-
- If SET is false and we're using the alternate sub-buffer, switch
- back to the saved sub-buffer. What this means is that the
- (current, alternate) sub-buffer is deleted (using `(delete-region
- term-home-marker (point-max))'), and then the `term-home-marker'
- is restored (from `term-saved-home-marker').
-

-File: term.info, Node: Input to the inferior, Prev: altsubbuffer, Up: Overview
-
-Input to the inferior
----------------------
-
- Characters typed by the user are sent to the inferior. How this is
-done depends on whether the `term' buffer is in "character" mode or
-"line" mode. (A `term' buffer can also be in "pager" mode. This is
-discussed <later>.) Which of these is currently active is specified in
-the mode line. The difference between them is the key-bindings
-available.
-
- In character mode, one character (by default <C-c>) is special, and
-is a prefix for various commands. All other characters are sent
-directly to the inferior process, with no interpretation by Emacs.
-Character mode looks and feels like a real terminal, or a conventional
-terminal emulator such as xterm.
-
- In line mode, key commands mostly have standard Emacs actions.
-Regulars characters insert themselves into the buffer. When return is
-typed, the entire current line of the buffer (except possibly the
-prompt) is sent to the inferior process. Line mode is basically the
-original shell mode from earlier Emacs versions.
-
- To switch from line mode to character mode type `C-c c'. To switch
-from character mode to line mode type `C-c l'.
-
- In either mode, "echoing" of user input is handled by the inferior.
-Therefor, in line mode after an input line at the end of the buffer is
-sent to the inferior, it is deleted from the buffer. This is so that
-the inferior can echo the input, if it wishes (which it normally does).

-
-Connecting to remote computers
-==============================
-
- If you want to login to a remove computer, you can do that just as
-you would expect, using whatever commands you would normally use.
-
- (This is worth emphasizing, because earlier versions of `shell' mode
-would not work properly if you tried to log in to some other computer,
-because of the way echoing was handled. That is why there was a
-separate `telnet' mode to partially compensate for these problems. The
-`telnet' mode is no longer needed, and is basically obsolete.)
-
- A program that asks you for a password will normally suppress
-echoing of the password, so the password will not show up in the buffer.
-This will happen just as if you were using a real terminal, if the
-buffer is in char mode. If it is in line mode, the password will be
-temporarily visible, but will be erased when you hit return. (This
-happens automatically; there is no special password processing.)
-
- When you log in to a different machine, you need to specify the type
-of terminal your using. If you are talking to a Bourne-compatible
-shell, and your system understands the `TERMCAP' variable, you can use
-the command `M-x shell-send-termcap', which sends a string specifying
-the terminal type and size. (This command is also useful after the
-window has changed size.)
-
- If you need to specify the terminal type manually, you can try the
-terminal types "ansi" or "vt100".
-
- You can of course run gdb on that remote computer. One useful
-trick: If you invoke gdb with the `--fullname' option, it will send
-special commands to Emacs that will cause Emacs to pop up the source
-files you're debugging. This will work whether or not gdb is running
-on a different computer than Emacs, assuming can access the source
-files specified by gdb.

-
-Paging
-======
-
- When the pager is enabled, Emacs will "pause" after each screenful
-of output (since the last input sent to the inferior). It will enter
-"pager" mode, which feels a lot like the "more" program: Typing a
-space requests another screenful of output. Other commands request
-more or less output, or scroll backwards in the `term' buffer. In
-pager mode, type `h' or `?' to display a help message listing all the
-available pager mode commands.
-
- In either character or line mode, type `C-c p' to enable paging, and
-`C-c D' to disable it.

-Terminal Escape sequences
-=========================
-
- A program that does "graphics" on a terminal controls the terminal
-by sending strings called "terminal escape sequences" that the terminal
-(or terminal emulator) interprets as special commands. The `term' mode
-includes a terminal emulator that understands standard ANSI escape
-sequences, originally popularized by VT100 terminals, and now used by
-the `xterm' program and most modern terminal emulator software.

-Escape commands for erasing text
---------------------------------
-
- These commands "erase" part of the sub-buffer. Erasing means
-replacing by white space; it is not the same as deleting. The relative
-screen positions of things that are not erased remain unchanged with
-each other, as does the relative cursor position.
-
-`E [ J'
- Erase from cursor to end of screen.
-
-`E [ 0 J'
- Same as E [ J.
-
-`E [ 1 J'
- Erase from home position to point.
-
-`E [ 2 J'
- Erase whole sub-buffer.
-
-`E [ K'
- Erase from point to end of screen line.
-
-`E [ 0 K'
- Same as E [ K.
-
-`E [ 1 K'
- Erase from beginning of screen line to point.
-
-`E [ 2 K'
- Erase whole screen line.

-
-Command hook
-------------
-
- If `C-z' is seen, any text up to a following <LF> is scanned. The
-text in between (not counting the initial C-z or the final LF) is
-passed to the function that is the value of `term-command-hook'.
-
- The default value of the `term-command-hook' variable is the
-function `term-command-hook', which handles the following:
-
-`C-z C-z FILENAME:LINENUMBER:IGNORED LF'
- Set term-pending-frame to `(cons "FILENAME" LINENUMBER)'. When
- the buffer is displayed in the current window, show the FILENAME
- in the other window, and show an arrow at LINENUMBER. Gdb emits
- these strings when invoked with the flag -fullname. This is used
- by gdb mode; you can also invoke gdb with this flag from shell
- mode.
-
-`C-z / DIRNAME LF'
- Set the directory of the term buffer to DIRNAME
-
-`C-z ! LEXPR LF'
- Read and evaluate LEXPR as a Lisp expression. The result is
- ignored.
