and when the command character is a control character, encoding the command character and sending the encoded command character to an operating system.
According to some embodiments of the invention, the output processor is to:
judging the type of the output character;
when the output character is a text character, directly sending the output character to a display unit in a byte mode;
and when the output character is the control character, decoding the output character and sending the decoded output character to the display unit.
According to some embodiments of the invention, a display unit is configured to:
and displaying the processed output characters on the interface based on the swing component, in other words, displaying the processed output characters in the form of the interface. The interface is provided by a panel in the swing component and can be used integrally.
According to some embodiments of the invention, the control character of the command character comprises at least one of the following characters: carriage return characters, tabulation characters, deletion characters, space characters, upper key characters, lower key characters, left key characters and right key characters.
According to some embodiments of the invention, the control character of the output character comprises a cursor. If 1A appears in the control character, the cursor needs to be moved up by one line for display.
According to some embodiments of the invention, the states of the cursor include a first state, a second state, and a third state;
a display unit for:
when the interface is selected, the cursor is alternately presented between a first state and a second state by refreshing the interface;
when the interface is not selected, the cursor keeps a third state;
storing historical text characters;
and acquiring and displaying the historical text characters and the latest text characters with the corresponding number according to the size of the current interface.
For example, when the display unit displays the cursor state, because the cursor needs to flash, the interface needs to be refreshed and redrawn continuously, and the precondition for redrawing the interface is that the current interface is selected. The cursor has three states, respectively: colored filled rectangles (first state), hidden (second state) and framed or unfilled (third state). When the interface is selected, the cursor state is alternately presented in a first state and a second state, the alternate presentation of the cursor is realized by refreshing the whole interface, and the state of the cursor is required to be changed and the character content is required to be reprinted when the interface is refreshed; when the interface is not selected, the cursor state is the third state, and the interface is not redrawn at the moment.
When the display unit displays the character content, the characters on the interface need to be stored because the interface needs to be redrawn continuously, and the characters are prevented from being lost during redrawing. The interface character content is divided into two parts: the latest character content and the historical character content. The latest character content refers to the latest character required to be displayed on the interface; the historical character content is displayed, characters which cannot be printed on the current interface are displayed, and the historical characters are displayed mainly when the interface is scrolled. The latest character content or the historical character content is stored according to a certain data structure. Fig. 2 is a schematic diagram of a storage structure of text characters, and it is to be noted here that the storage structure of character contents respectively has two lists, namely a horizontal list and a vertical list, the horizontal list stores the character contents of each line, and the vertical list stores all line objects.
Note that the drawing of the interface includes printing of a cursor and printing of characters, and the cursor printing mainly alternates states every refresh, and it should be noted here that the cursor position changes depending on the content of the drawing. The basic unit of character printing is a single character, a character object list needing to be printed is recalculated according to the size of the current interface before the interface is drawn each time, in the drawing process, each character row object in the list is traversed, each character in each character row object is traversed for drawing, and the current cursor position needs to be continuously updated during drawing so as to facilitate the drawing of a cursor.
According to some embodiments of the invention, the processing unit interacts with the operating system through a virtual terminal PTY.
If the command character is a text character, the input processor will send the text character directly to the PTY in bytes; if the command character is a control character, the input processor will perform preliminary processing on the command character, which mainly includes encoding the command character, and then send the processed command character to the PTY.
And after receiving the processed command characters sent by the input processor, the PTY transfers the command characters to the operating system for processing, and sends the processing result of the operating system to the output processor.
The PTY may be provided by the operating system and the specific meaning of the entered command characters in the operating system is done by the PTY.
The swen-based interactable system command line tool according to embodiments of the present invention is described in detail in one specific embodiment with reference to fig. 1-2. It is to be understood that the following description is illustrative only and is not intended to be in any way limiting. All similar structures and similar variations thereof adopted by the invention are intended to fall within the scope of the invention.
As shown in FIG. 1, the swing-based interactive system command line tool of the embodiment of the present invention comprises an input processor, an output processor, and a display unit (i.e., the interface shown in the figure).
The input processor is used for creating a monitor to monitor the input operation of the keyboard, and whether the input command character is a text character or a control character is judged in the input processor. If the character is a text character, the character is directly sent to the PTY in a byte mode; if the control character is the control character, the input processor needs to perform preliminary processing, mainly encode the command character, and then send the processed command character to the PTY.
The PTY is used for receiving the command characters sent by the input processor, transferring the command characters to an operating system for processing, and then sending the processing result to the output processor.
The output processor is used for receiving the output character returned by the PTY. There are two types of output characters, text characters and control characters. If the received characters are common text characters, directly delivering the characters to an interface of a display unit for printing; if the received control character is the control character, the control character needs to be analyzed, and then corresponding operation is carried out according to the result.
It should be noted here that it is necessary to distinguish between control characters in the input processor and control characters in the output processor, where the control characters represent different meanings in different processors. In the input manager, the control characters are non-displayable characters such as enter, tab, delete, space, up, down, left, right, and the like. In the output manager, the control character is a character for controlling printing behavior, and is mainly used for controlling the position of a cursor in an interface (the cursor represents the starting position of the next character printing and is displayed in a flashing manner), and if 1A appears in the control character, the cursor needs to be moved upwards by one line for display.
The display unit is responsible for printing the output characters to be displayed, and the characters seen on the interface are not directly input by the keyboard but are controlled by the output processor.
The interface printing mainly comprises two parts, namely character content and a cursor, and the printing principle of the interface is explained in detail below.
1. Cursor state:
because the cursor needs the effect of flickering, the interface needs to be refreshed and redrawn continuously, and the precondition for redrawing the interface is that the current interface is selected. The cursor has three states, respectively: colored filled rectangles (first state), hidden (second state) and framed or unfilled (third state). When the interface is selected, the cursor state is alternately presented in a first state and a second state, the alternate presentation of the cursor is realized by refreshing the whole interface, and the state of the cursor is required to be changed and the character content is required to be reprinted when the interface is refreshed; when the interface is not selected, the cursor state is the third state, and the interface is not redrawn at the moment.
2. The character content structure is as follows:
because the interface needs to be redrawn continuously, the characters on the interface need to be stored, and are prevented from being lost during redrawing. The interface character content is divided into two parts: the latest character content and the historical character content. The latest character content refers to the latest character required to be displayed on the interface; the historical character content is displayed, characters which cannot be printed on the current interface are displayed, and the historical characters are displayed mainly when the interface is scrolled. The latest character content or the historical character content is stored according to a certain data structure. Fig. 2 is a schematic diagram of a storage structure of text characters, and as shown in fig. 2, the storage structure of character contents respectively includes two lists, namely a horizontal list and a vertical list, the horizontal list stores the character contents of each line, and the vertical list stores all line objects.
3. Drawing an interface:
the drawing of the interface includes the printing of the cursor and the printing of the characters, the cursor printing mainly alternates states every time the refresh is performed, which is described in detail in 1, and it should be noted that the cursor position may change according to the content of the drawing. The basic unit of character printing is a single character, a character object list needing to be printed is recalculated according to the size of the current interface before the interface is drawn each time, in the drawing process, each character row object in the list is traversed, each character in each character row object is traversed for drawing, and the current cursor position needs to be continuously updated during drawing so as to facilitate the drawing of a cursor.
The embodiment of the invention can really realize the execution of the command line of the operating system, because the PTY mechanism based on the operating system can run all commands in the operating system, and the commands can be interactive or non-interactive. The method can be integrated into graphical software developed based on java, can be independently operated, can also be embedded into other graphical software developed based on java for use, meets most of use requirements, is realized based on linux bottom layer PTY, is developed by using java, is independent of a platform architecture, and has a wide use range.
It should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention, and those skilled in the art can make various modifications and changes. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
