Alcor6L/eLua/term

This module contains functions for accessing ANSI-compatible terminals (and terminal emulators) from Lua. Functions term.clrscr Clear the screen term.clrscr() term.clreol Clear from the current cursor position to the end of the line term.clreol() term.moveto Move the cursor to the specified coordinates term.moveto( x, y ) x - the column (starting with 1) y - the line (starting with 1) term.moveup Move the cursor up term.moveup( delta ) delta - number of lines to move the cursor up. term.movedown Move the cursor down term.movedown( delta ) delta - number of lines to move the cursor down term.moveleft Move the cursor left term.moveleft( delta ) delta - number of columns to move the cursor left term.moveright Move the cursor right term.moveright( delta ) delta - number of columns to move the cursor right term.getlines Get the number of lines in the terminal numlines = term.getlines() Returns: numlines - The number of lines in the terminal term.getcols Get the number of columns in the terminal numcols = term.getcols() Returns: numcols - The number of columns in the terminal term.print Write one or more strings in the terminal term.print( [ x, y ], str1, [ str2, ..., strn ] ) x (optional) - write the string at this column. If x is specified, y must also be specified y (optional) - write the string at this line. If y is specified, x must also be specified str1 - the first string to write str2 (optional) - the second string to write strn (optional) - the nth string to write getcx Get the current column of the cursor cx = term.getcx() Returns: cx - The column of the cursor term.getcy Get the current line of the cursor cy = term.getcy() Returns: cy - The line of the cursor term.getchar Read a char (a key press) from the terminal ch = term.getchar( [ mode ] ) mode (optional) - terminal input mode. It can be either: term.WAIT - wait for a key to be pressed, then return it. This is the default behaviour if mode is not specified. term.NOWAIT - if a key was pressed on the terminal return it, otherwise return -1. Returns: ch - The char read from a terminal or -1 if no char is available. The 'char' can be an actual ASCII char, or a 'pseudo-char' which encodes special keys on the keyboard. The list of the special chars and their meaning is given in the table below: Key code MeaningKC_UP the UP key on the terminalKC_DOWN the DOWN key on the terminalKC_LEFT the LEFT key on the terminalKC_RIGHT the RIGHT key on the terminalKC_HOME the HOME key on the terminalKC_END the END key on the terminalKC_PAGEUP the PAGE UP key on the terminalKC_PAGEDOWN the PAGE DOWN key on the terminalKC_ENTER the ENTER (CR) key on the terminalKC_TAB the TAB key on the terminalKC_BACKSPACE the BACKSPACE key on the terminalKC_ESC the ESC (escape) key on the terminal
