Embodiment 5
With reference to Fig. 6,8,9,10, present embodiment discloses a kind of concrete scheme of method of identification terminal order line.At first, obtain input data and dateout between terminal and the main frame.Then dateout is simulated by pseudo-terminal, obtained output content, described output content comprises displaying contents and SOT state of termination.
Wait for input data or output content; When input, judge the state that the current command is discerned according to input data and dateout, about the method for judging the state that the current command is discerned following three kinds of methods are arranged, be applicable to different concrete applied environments:
Method one, with reference to Fig. 8, establishing default state is the program output state; When receiving input data 802, state transfers the order input state to, is that state transfers the program output state to when ordering acknowledge character, command execution character or order cancellation character 203 until these input data or input data afterwards.
For the ease of understanding the method one in the present embodiment, with the following example that is operating as: when the user after CMD " [user@host dir] ", input command " 1s-1 ", and carry out by carriage return; Computer is carried out the 1s program, shows the output result, and then display command prompt " [user@host dir] $ ".
For the mentioned order input, from user key-press, the state of command recognition becomes the order input state from the program output state variable.At this moment the displaying contents of terminal simulator is " [user@host dir] $ ", and writing down prompt length simultaneously is 17 (spaces that comprise afterbody).When the user pressed enter key by the time, the displaying contents of terminal simulator became " [user@host dir] $1s-1 ", just thought at this moment in the buffering area that the displaying contents behind the 17th character is exactly the order of user's input and gives record; Be the status modifier of command recognition the program output state then, after this show occur from this command execution to next prompt before the terminal output content all regard the direct record of output of program as, so but next prompt itself do not stopped can not exporting immediately as yet owing to this row by line feed character.Write down the order line of identification, this moment, the state of command recognition was got back to the program output state again, waited the order line of next input to be identified.
If the input process of last example is, at first input " 1-1 " moves to cursor by the CTRL-A Macintosh then and presses " s " after capable head moves to second lattice to cursor with Right Arrow or CTRL-F Macintosh again and return the car operation then.Although can produce more complicated terminal control sequence, the displaying contents that is obtained by terminal simulator at last all is the same, and order line still can be by correct identification.
Method two: with reference to Fig. 9, default state is the program output state; When receiving input data 802, state transfers the order input state to, is that state transfers the program output state to when ordering acknowledge character, command execution character or order cancellation character 203 until these input data or input data afterwards; When the input data when helping character 204, state transfers the command cue state to, until when to import data be non-help character 902, state transfers the order input state to.
For the ease of understanding the method two in the present embodiment, with the following example that is operating as: the user presses tab key after having imported " 1s-1R ", this moment tab key to be operated system definition be help button, " EADME " five characters of the automatic completion of operating system meeting back, the user directly carries out this order by carriage return then.
Concrete identifying is, the state of command recognition enters the order input state when the user begins to import, " EADME " that shows after the user presses TAB when terminal enters the buffering area of terminal simulator automatically, and this moment, displaying contents was correct order " 1s-1 README ".
In last example, if the file with the R beginning under the current directory has " README " and " RELEASES " two, the user presses the TAB key after having imported " 1s-1R ", operating system is replenished the E character at first automatically, line feed shows " README " and " RELEASES " two filenames then, again the part order " 1s-1RE " that enters a new line the display command prompt afterwards and finished, the user sees prompting back input A character and presses the TAB key that the automatic completion of operating system " DME " character forms complete order " 1s-1 README ".
Concrete identifying is, system is receiving the user when importing the TAB character, the state of command recognition enters the command cue state, operating system shows that newline, optional file name are pointed out and order line is not finished in the demonstration that enters a new line again afterwards, and the terminal output of this moment can be recorded to the output procedure file but can not be considered to order carries out record.Press A key and last enter key up to the user, the state of command recognition reenters the order input state again, so complete order " 1s-1 README " can go on record.
Method three: with reference to Figure 10, default state is the program output state; When dateout is that state transfers the interactive application state to when entering the characteristic sequence 206 of interaction mode, until being that state transfers the program output state to when withdrawing from the characteristic sequence 207 of interaction mode when dateout; When receiving input data 802, state transfers the order input state to, is that state transfers the program output state to when ordering acknowledge character, command execution character or order cancellation character 203 until these data data or input data afterwards; When the input data when helping character 204, state transfers the command cue state to, until when to import data be non-help character 902, state transfers the order input state to.
For the ease of understanding the method three in the present embodiment, with the following example that is operating as: user's utility command " viREADME " operation vi program is edited the file of a README by name.He need add that content is the delegation of " [user@host dir] $hello " in end of file, therefore he moves on to tail of file to cursor by the G key earlier, sets up a newline by the o key again, word for word squeezes into after this row content by carriage return, press esc key then, ZZ preserves file and withdraws from.
Concrete identifying is, under the VT102 terminal, vi can be by show state when entering interactive editor's pattern sequence " ESC[? 1049h " switch to standby screen (alternative screen), after detecting this sequence, the state of command recognition switches to the interactive application state, ensuing operation can not be recorded, withdraw from vi up to the user, the sequence of terminal output show state " ESC[? 10491 " switch back original screen, after detecting this sequence, the state of command recognition becomes the program output state.Wait for next step operation of terminal use.
Above-mentioned help character 204 be tab key or "? " key.Above-mentioned common character is the input character except helping character or order acknowledge character or command execution character.The above-mentioned characteristic sequence 206 that enters interaction mode is: No. 47, the pattern that is provided with of VT102 and compatible terminal, and/or No. 1047, the pattern that is provided with of VT102 and compatible terminal, and/or No. 1049, the pattern that is provided with of VT102 and compatible terminal, and/or No. 1, the pattern that is provided with of VT100 and compatible terminal.The above-mentioned characteristic sequence 207 that withdraws from interaction mode is: No. 47, the removing pattern of VT102 and compatible terminal, and/or No. 1047, the removing pattern of VT102 and compatible terminal, and/or No. 1049, the removing pattern of VT102 and compatible terminal, and/or No. 1, the removing pattern of VT100 and compatible terminal.
