If the selected text is - a null string, it is indicated by a hairline cursor between two - characters. The selected text may be edited by mousing and typing. - Text is selected by pointing and clicking button 1 to make a null- - string selection, or by pointing, then sweeping with button 1 - pressed. Text may also be selected by double-clicking: just inside - a matched delimiter-pair with one of <tt><font size=+1>{[(<`'"</font></tt> on the left and <tt><font size=+1>}])>`'"</font></tt> - on the right, it selects all text within the pair; at the beginning - or end of a line, it selects the line; within or at the - edge of an alphanumeric word, it selects the word. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Characters typed on the keyboard replace the selected text; if - this text is not empty, it is placed in a <i>snarf buffer</i> common - to all windows but distinct from that of <a href="../man1/sam.html"><i>sam</i>(1)</a>. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Programs access the text in the window at a single point maintained - automatically by <i>9term</i>. The <i>output point</i> is the location in the - text where the next character written by a program to the terminal - will appear; afterwards, the output point is the null string beyond - the new character. The output point is also the location - in the text of the next character that will be read (directly - from the text in the window, not from an intervening buffer) by - a program. Since Unix does not make it possible to know when a - program is reading the terminal, lines are sent as they are completed - (when the user types a newline character). - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - In general there is text in the window after the output point, - usually placed there by typing but occasionally by the editing - operations described below. A pending read of the terminal will - block until the text after the output point contains a newline, - whereupon the read may acquire the text, up to and including the - newline. After the read, as described above, the output point - will be at the beginning of the next line of text. In normal circumstances, - therefore, typed text is delivered to programs a line at a time. - Changes made by typing or editing before the text is read will - not be seen by the program reading it. Because of the - Unix issues mentioned above, a line of text is only editable until - it is completed with a newline character, or when hold mode (see - below) is enabled. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Even when there are newlines in the output text, <i>9term</i> will not - honor reads if the window is in <i>hold mode</i>, which is indicated - by a white cursor and blue text and border. The ESC character - toggles hold mode. Some programs automatically turn on hold mode - to simplify the editing of multi-line text; type ESC when done - to allow <i>mail</i> to read the text. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - An EOT character (control-D) behaves exactly like newline except - that it is not delivered to a program when read. Thus on an empty - line an EOT serves to deliver an end-of-file indication: the read - will return zero characters. The BS character (control-H) erases - the character before the selected text. The ETB character - (control-W) erases any nonalphanumeric characters, then the alphanumeric - word just before the selected text. ‘Alphanumeric’ here means - non-blanks and non-punctuation. The NAK character (control-U) - erases the text after the output point, and not yet read by a - program, but not more than one line. All these - characters are typed on the keyboard and hence replace the selected - text; for example, typing a BS with a word selected places the - word in the snarf buffer, removes it from the screen, and erases - the character before the word. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - An ACK character (control-F) or Insert character triggers file - name completion for the preceding string (see <a href="../man3/complete.html"><i>complete</i>(3)</a>). - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Text may be moved vertically within the window. A scroll bar on - the left of the window shows in its clear portion what fragment - of the total output text is visible on the screen, and in its - gray part what is above or below view; it measures characters, - not lines. Mousing inside the scroll bar moves text: clicking - button 1 - with the mouse pointing inside the scroll bar brings the line - at the top of the window to the cursor’s vertical location; button - 3 takes the line at the cursor to the top of the window; button - 2, treating the scroll bar as a ruler, jumps to the indicated - portion of the stored text. Holding a button pressed in the scroll - bar will - cause the text to scroll continuously until the button is released. - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Typing down-arrow scrolls forward one third of a window, and up-arrow - scrolls back. Typing page-down scrolls forward two thirds of a - window, and page-up scrolls back. Typing Home scrolls to the top - of the window; typing End scrolls to the end. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The DEL character sends an <tt><font size=+1>interrupt</font></tt> note to all processes in - the window’s process group. Unlike the other characters, the DEL - and arrow keys do not affect the selected text. The left (right) - arrow key moves the selection to one character before (after) - the current selection. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>9term</i> relies on the kernel’s terminal processing to handle EOT - and DEL, so the terminal must be set up with EOT as the “eof” - character and DEL as the “intr” character. <i>9term</i> runs <a href="../man1/stty.html"><i>stty</i>(1)</a> - to establish this when the terminal is created. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Normally, written output to a window blocks when the text reaches - the end of the screen and the terminal buffer fills; a button - 2 menu item toggles scrolling. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>9term</i> changes behavior according to the terminal settings of the - running programs. Most programs run with echo enabled. In this - mode, <i>9term</i> displays and allows editing of the input. Some programs, - typically those reading passwords, run with echo disabled. In - this mode, <i>9term</i> passes keystrokes through directly, - without echoing them or buffering until a newline character. These - heuristics work well in many cases, but there are a few common - ones where they fall short. First, programs using the GNU readline - library typically disable terminal echo and perform echoing themselves. - The most common example is the shell - <a href="../man1/bash.html"><i>bash</i>(1)</a>. Disabling the use of readline with “<tt><font size=+1>set +o emacs</font></tt>” [<i>sic</i>] - usually restores the desired behavior. Second, remote terminal - programs such as <a href="../man1/ssh.html"><i>ssh</i>(1)</a> typically run with echo disabled, relying - on the remote system to echo characters as desired. Plan 9’s <i>ssh</i> - has a <tt><font size=+1>−C</font></tt> flag to disable this, leaving the terminal in - “cooked” mode. For similar situations on Unix, <i>9term</i>’s button - 2 menu has an entry to toggle the forced use of cooked mode, despite - the terminal settings. In such cases, it is useful to run “<tt><font size=+1>stty - −echo</font></tt>” on the remote system to avoid seeing your input twice. - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Editing operations are selected from a menu on button 2. The <tt><font size=+1>cut</font></tt> - operation deletes the selected text from the screen and puts it - in the snarf buffer; <tt><font size=+1>snarf</font></tt> copies the selected text to the buffer - without deleting it; <tt><font size=+1>paste</font></tt> replaces the selected text with the - contents of the buffer; and <tt><font size=+1>send</font></tt> copies the snarf buffer to - just after the output point, adding a final newline if missing. - <tt><font size=+1>Paste</font></tt> will sometimes and <tt><font size=+1>send</font></tt> will always place text after the - output point; the text so placed will behave exactly as described - above. Therefore when pasting text containing newlines after the - output point, it may be prudent to turn on hold mode first. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The <tt><font size=+1>plumb</font></tt> menu item sends the contents of the selection (not the - snarf buffer) to the <i>plumber</i> (see <a href="../man1/plumb.html"><i>plumb</i>(1)</a>). If the selection - is empty, it sends the white-space-delimited text containing the - selection (typing cursor). A typical use of this feature is to - tell the editor to find the source of an error by plumbing the - file and - line information in a compiler’s diagnostic. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Each <i>9term</i> listens for connections on a Unix socket. When a client - connects, the <i>9term</i> writes the window contents to the client and - then hangs up. <i>9term</i> installs the name of this socket in the environment - as <tt><font size=+1>$text9term</font></tt> before running <i>cmd</i>.<br> - -</table> -<p><font size=+1><b>SOURCE </b></font><br> - -<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - <tt><font size=+1>/usr/local/plan9/src/cmd/9term<br> - </font></tt> -</table> -<p><font size=+1><b>BUGS </b></font><br> - -<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - There should be a program to toggle the current window’s hold - mode. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Unix makes everything harder.<br> - -</table> -<p><font size=+1><b>SEE ALSO </b></font><br> - -<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - <a href="../man1/wintext.html"><i>wintext</i>(1)</a><br> - -</table> - -<td width=20> -<tr height=20><td> -</table> -<!-- TRAILER --> -<table border=0 cellpadding=0 cellspacing=0 width=100%> -<tr height=15><td width=10><td><td width=10> -<tr><td><td> -<center> -<a href="../../"><img src="../../dist/spaceglenda100.png" alt="Space Glenda" border=1></a> -</center> -</table> -<!-- TRAILER --> -</body></html> |
