The bulk of this manual + page describes the user interface. + + The _r_e_a_d_l_i_n_e routine returns a line of text with the trailing newline + removed. The data is returned in a buffer allocated with _m_a_l_l_o_c(3), so the + space should be released with _f_r_e_e(3) when the calling program is done with + it. Before accepting input from the user, the specified _p_r_o_m_p_t is dis- + played on the terminal. + + The _a_d_d___h_i_s_t_o_r_y routine makes a copy of the specified _l_i_n_e and adds it to + the internal history list. + + User Interface + + A program that uses this library provides a simple emacs-like editing + interface to its users. A line may be edited before it is sent to the + calling program by typing either control characters or escape sequences. A + control character, shown as a caret followed by a letter, is typed by hold- + ing down the ``control'' key while the letter is typed. For example, + ``^A'' is a control-A. An escape sequence is entered by typing the + ``escape'' key followed by one or more characters. The escape key is + abbreviated as ``ESC.'' Note that unlike control keys, case matters in + escape sequences; ``ESC F'' is not the same as ``ESC f''. + + An editing command may be typed anywhere on the line, not just at the + beginning. In addition, a return may also be typed anywhere on the line, + not just at the end. + + Most editing commands may be given a repeat count, _n, where _n is a number. + To enter a repeat count, type the escape key, the number, and then the com- + mand to execute. For example, ``ESC 4 ^f'' moves forward four characters. + If a command may be given a repeat count then the text ``[n]'' is given at + the end of its description. + + The following control characters are accepted: + ^A Move to the beginning of the line + ^B Move left (backwards) [n] + ^D Delete character [n] + ^E Move to end of line + ^F Move right (forwards) [n] + ^G Ring the bell + ^H Delete character before cursor (backspace key) [n] + ^I Complete filename (tab key); see below + ^J Done with line (return key) + ^K Kill to end of line (or column [n]) + ^L Redisplay line + ^M Done with line (alternate return key) + ^N Get next line from history [n] + ^P Get previous line from history [n] + ^R Search backward (forward if [n]) through history for text; + must start line if text begins with an uparrow + ^T Transpose characters + ^V Insert next character, even if it is an edit command + ^W Wipe to the mark + ^X^X Exchange current location and mark + ^Y Yank back last killed text + ^[ Start an escape sequence (escape key) + ^]c Move forward to next character ``c'' + ^? Delete character before cursor (delete key) [n] + + The following escape sequences are provided. + ESC ^H Delete previous word (backspace key) [n] + ESC DEL Delete previous word (delete key) [n] + ESC SP Set the mark (space key); see ^X^X and ^Y above + ESC . Get the last (or [n]'th) word from previous line + ESC ? Show possible completions; see below + ESC < Move to start of history + ESC > Move to end of history + ESC b Move backward a word [n] + ESC d Delete word under cursor [n] + ESC f Move forward a word [n] + ESC l Make word lowercase [n] + ESC u Make word uppercase [n] + ESC y Yank back last killed text + ESC v Show library version + ESC w Make area up to mark yankable + ESC nn Set repeat count to the number nn + ESC C Read from environment variable ``_C_'', where C is + an uppercase letter + + The _e_d_i_t_l_i_n_e library has a small macro facility. If you type the escape + key followed by an uppercase letter, _C, then the contents of the environ- + ment variable ___C__ are read in as if you had typed them at the keyboard. + For example, if the variable ___L__ contains the following: + ^A^Kecho '^V^[[H^V^[[2J'^M + Then typing ``ESC L'' will move to the beginning of the line, kill the + entire line, enter the echo command needed to clear the terminal (if your + terminal is like a VT-100), and send the line back to the shell. + + The _e_d_i_t_l_i_n_e library also does filename completion. Suppose the root + directory has the following files in it: + bin vmunix + core vmunix.old + If you type ``rm /v'' and then the tab key. _E_d_i_t_l_i_n_e will then finish off + as much of the name as possible by adding ``munix''. Because the name is + not unique, it will then beep. If you type the escape key and a question + mark, it will display the two choices. If you then type a period and a + tab, the library will finish off the filename for you: + rm /v[TAB]_m_u_n_i_x.TAB_o_l_d + The tab key is shown by ``[TAB]'' and the automatically-entered text is + shown in italics. + + + +BUGS AND LIMITATIONS + Cannot handle lines more than 80 columns. + + + + +AUTHORS + Simmule R.
