[0043] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0044] The text printing method provided by the embodiments of the present application can be applied to an application environment as shown in Figure 1 . Wherein, the terminal 102 communicates with the server 104 through the network, and the printer 106 communicates with the server 104 through the network. The data storage system can store the data required to be processed by the server 104. The data storage system can be integrated on the server 104, or placed on other network servers. The server 104 is used to determine the source statement in the print instruction when the print instruction sent by the terminal 102 is obtained, and perform lexical analysis on the source statement to obtain a data stream including a plurality of word nodes; the server 104 is also used to perform syntax analysis on the data stream, according to the target statement, and load resources on the preset environment, so that the printer 106 prints out the text printing result. Wherein, the terminal 102 can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things device can be a smart speaker, a smart TV, a smart air conditioner, a smart vehicle device, etc. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, etc. The server 104 can be a cloud server, or can be implemented by an independent server or a server cluster composed of multiple servers.

[0045] In one of the embodiments, as shown in Figure 2 , a text printing method is provided, which is described by taking the application of the computer device as an example. The computer device can be the terminal or the server in Figure 1 , including the following steps:

[0046] Step 202, when the print instruction is obtained, the source statement in the print instruction is determined.

[0047] Wherein, the source statement can be a kind of source code, such as C-Lodop source code. The source statement can also represent a statement edited by the user according to different printing requirements.

[0048] Specifically, the computer device can determine the print instruction in response to the triggering operation of the user. At this time, the print instruction includes all the codes required to execute the printing task. Since all the codes also include the basic printing statements that do not need to be modified at each printing, the computer device can parse the source statement edited and modified by the user from the print instruction.

[0049] In one of the embodiments, before determining the source statement in the print instruction, further comprising: obtaining a technical document; obtaining the source statement according to the technical document and in response to an editing operation on the print function; and generating the print instruction in response to a triggering operation on the print control and in combination with the source statement and a print statement corresponding to the print control.

[0050] The technical document includes a plurality of print functions; the print functions are embodied by corresponding functions; the technical document can be a technical document of different versions of C-Lodop print control, i.e., the technical document specifies the standard of C-Lodop print control; the print control exists in the form of a special plug-in; the special plug-in can be a browser plug-in, i.e., in the traditional scheme, the user can execute the corresponding print instruction only when the user triggers the computer device that only provides a browser.

[0051] Specifically, since the technical document can be pre-stored in a database, such as a third-party database corresponding to a preset environment, when the technical document is obtained from the database, the user can use it as an editing basis to obtain the corresponding source statement. For example, when there is a function ADD_PRINT_TEXT, the specification of the corresponding source statement is ADD_PRINT_TEXT(intTop, intLeft, intWidth, intHeight, strContent), and the embodied print function is to add a pure text print option, set the position and area size of the print item in the paper, and automatically wrap the text content in the area, i.e., after initialization, a line drawing class function is called to implement printing. When the computer device responds to the triggering operation of the user on the print control, the edited source statement and the basic print statement corresponding to the print control can be combined to generate the print instruction.

[0052] In one of the embodiments, the source statement is not limited to the edited code, but can also refer to all the codes required to execute the print task.

[0053] In step 204, the source statement is subjected to lexical analysis to obtain a data stream including a plurality of word nodes.

[0054] Specifically, the computer device pre-processes the source statement, and then filters out redundant information such as spaces and comments. Then the computer device can scan the source statement as a character sequence from left to right, i.e., scan the word stream constituting the source statement according to the lexical rules of the source code language, and identify the words according to the word formation rules. Since lexical analysis is the process of converting a character sequence into a token sequence, a token is a word, which is the smallest unit constituting the source code, therefore, the process of generating tokens from the input character sequence is called tokenization, i.e., each word in the input character sequence is divided into tokens.

[0055] For example, the character sequence of the source statement is LODOP. ADD_PRINT_TEXT (10, 10, 100, 100, "hello"), and ten lexical units are formed by lexical analysis as follows: <lodop>、<.>、<ADD_PRINT_TEXT> 、<(>、 <10> , <10> , <100> , <100> 、<"hello">、<)>.

[0056] Since each lexical unit corresponds to a word, when a computer device connects multiple lexical units sequentially, a data stream is obtained, and the lexical unit is the corresponding word node in the data stream. This data stream can be a token-formatted data stream.

[0057] In one embodiment, lexical analysis can be performed using a lexical analyzer.

[0058] Step 206: Perform syntax analysis on the data stream to obtain the target syntax tree, and compile the target syntax tree into a target statement suitable for a preset environment.

[0059] In one embodiment, performing syntactic analysis on the data stream to obtain a target syntax tree includes: determining the target function corresponding to the data stream from multiple word nodes; determining the target grammar corresponding to the target function; and constructing the target syntax tree from the bottom up based on the target grammar.

[0060] Among them, word nodes include nodes that represent functions; the function's functionality corresponds to the printing function in technical documents; the target grammar includes top-and-bottom-free grammars, which are a way of describing programming languages, using simple symbols to describe a set of languages.

[0061] Specifically, because word nodes in a data stream have different word types, computer devices can identify string-type word nodes by parsing the data stream, and then identify the word node representing the function's functionality from among multiple word nodes. For example, referring to the example above, the identified word node is...<ADD_PRINT_TEXT> Since ADD_PRINT_TEXT is a function described in the technical documentation, it is used as the target function corresponding to the data stream. Because the target grammar is used to construct the syntax tree, it is necessary to determine the target grammar corresponding to the target function. This allows for a bottom-up approach to construct the target syntax tree from the data stream.

[0062] Furthermore, the computer device compiles the target syntax tree (AST) to perform code conversion according to pre-defined conversion rules between natural language code and the code of a preset environment, thereby obtaining the final target statement. The target statement is the code that can be executed by the printer to implement C-Lodop functionality. The preset environment can be the environment in which a Java program runs.

[0063] In one of the embodiments, the syntax analysis can be completed by a syntax analyzer. The syntax analyzer can form a plurality of lexical units into an Abstract Syntax Tree (AST) according to the relationship between the plurality of lexical units.

[0064] In one of the embodiments, the target grammar can be obtained by being pre-defined by a user, thereby improving the flexibility of constructing different syntax trees.

[0065] In step 208, the text printing result is obtained by loading resources of the preset environment according to the target sentence.

[0066] In one of the embodiments, the text printing result is obtained by loading resources of the preset environment according to the target sentence, including: loading database resources corresponding to the preset environment, and obtaining an installation package file by integrating the target sentence and the database resources; when the installation package file is triggered, a printer interface is called to make a target printer corresponding to the printer interface print the text printing result.

[0067] The installation package file includes the printer interface. The installation package file integrates a function interface provided by a software development kit and installation package resource information corresponding to the software development kit, etc. The software development kit is, for example, an SDK. The SDK can be regarded as a software delivery form. Through the SDK, the complete content of the software code and resources of an initial application program can be packaged, and the packaged file can be integrated when delivered to another party.

[0068] Specifically, since the target sentence is applicable to the preset environment, when the target sentence with the corresponding printing function is formed, the computer device can also load other database resources corresponding to the preset environment, thereby expanding the ecology of the preset environment, realizing the use of the third-party database, and further forming an installation package file with small memory size and easy to trigger.

[0069] Further, when the computer device adopts a server of a Spring framework, the resources of the corresponding server can be directly used. By introducing the installation package file, when the user triggers the installation package file, the computer device can call the printer interface to make a target printer corresponding to the printer interface print the text printing result. Since the installation package file includes a plurality of function interfaces, the computer device integrated with the C-Lodop printing control expands the function, and further realizes the system call of the interface operation.

[0070] In one of the embodiments, the computer device can also print the trigger by remote JavaScript programming.

[0071] In the text printing method, the source statement in the printing instruction is determined, and the source statement is subjected to lexical analysis to obtain a data stream including a plurality of word nodes; when the data stream is subjected to syntax analysis, a target syntax tree is obtained, and the target syntax tree is compiled into a target statement suitable for a preset environment; in this way, the target statement can be obtained according to the target statement, and resource loading is performed on the preset environment to obtain a text printing result. Since the source statement is analyzed by lexical analysis and syntax analysis in sequence, the target statement suitable for the preset environment can be obtained, and in this way, the C-Lodop printing control is separated from the use of the browser, and the use of the C-Lodop printing control in the preset environment is expanded. In addition, during the resource loading process on the preset environment, a plurality of function interfaces can be obtained, so that system calls such as interface operations can be implemented.

[0072] In one of the embodiments, the source statement is subjected to lexical analysis to obtain a data stream including a plurality of word nodes, including: determining a plurality of words in the source statement, and performing semantic recognition on each word by a finite state automaton to obtain a word node and a word type corresponding to each word respectively; marking the corresponding word node with a plurality of word types to obtain a marked word node; and concatenating a plurality of marked word nodes in the order of arrangement of each word to obtain the data stream.

[0073] Specifically, the computer device performs semantic recognition on each word in the source statement by a finite state automaton (DFA) to obtain a word node and a word type corresponding to each word respectively. The DFA is a five-tuple M = Σ (S, S0, f, Z), where Σ represents each character, i.e., each word; S represents the state of each character; S0 represents the initial state; f represents the transformation function; and Z represents the final state set. The word type can include a string, an integer, a floating-point number, and a punctuation mark, etc. When the five-tuple M is represented in the form of a node set of a graph, an initial structure of the data stream can be obtained. Since each word node corresponds to a word type, when the corresponding word node is marked by the word type, a marked word node can be obtained, and then a plurality of marked word nodes are concatenated in the order of arrangement of each word to form a data stream corresponding to the source statement, i.e., a data stream in the Token format with states.

[0074] For example, when the source statement is LODOP.ADD_PRINT_TEXT(10, 10, 100, 100, "hello"), the DFA graph obtained by recognition is as shown in Figure 3 Figure 3 which is a structural schematic diagram of the data stream in one of the embodiments.

[0075] ​In one embodiment, when the source statement is INT:'-'? [0-9]+, it represents the recognition of positive and negative integers, numbers such as 10, -10, etc.; when the source statement is FLOAT:([0-9]+'.'[0-9]+), it represents the recognition of numbers with decimal points, such as 0.12, etc.

[0076] In this embodiment, by using a finite state automaton to perform lexical analysis on the source statement, the lexical units of the source statement can be accurately analyzed, so that the corresponding syntax tree can be accurately obtained when constructing the syntax tree in the subsequent process, thereby improving the accuracy of printing the text.

[0077] In one embodiment, such as Figure 4 As shown, Figure 4 This is a flowchart illustrating the process of constructing the target syntax tree. Based on the target grammar, the data flow is constructed into the target syntax tree from the bottom up, which also includes the following steps:

[0078] Step S402: Take the initial node in the data stream as the root node in the target syntax tree, and traverse the multiple word nodes in the data stream.

[0079] Specifically, the computer device identifies the initial node in the data stream and uses it as the root node in the target syntax tree. (See reference) Figure 3 The initial node in is <lodop>The computer device starts from the root node and traverses multiple word nodes in the data stream. Since the matching process of each word node is the same, the current word node is taken as an example for illustration. For example, the current word node is <ADD_PRINT_TEXT>.

[0080] In step S404, the current word node is matched with multiple productions in the target grammar to obtain matching sub-results, and the multiple matching sub-results and the root node are integrated to obtain the target syntax tree.

[0081] In one embodiment, matching the current word node with multiple productions in the target grammar to obtain matching sub-results includes: taking the current word node as an edge node in the target syntax tree; determining a target production matched with the edge node from the multiple productions, and taking a non-terminal symbol in the head of the target production as a parent node of the edge node; taking the parent node as a new edge node, and returning to the process of determining a target production matched with the edge node from the multiple productions, until the non-terminal symbol is the root node; and integrating all edge nodes to obtain the matching sub-result corresponding to the current word node.

[0082] The target grammar includes multiple productions; a production includes a head; and the head is a non-terminal symbol. For example, the production 1 corresponding to an integer in the target grammar is D->0|1|...|10, the production 2 corresponding to a letter is L->a|b|c|d...|z, and the production 3 corresponding to the integration of a digit and a letter is P->L|D, i.e., P can be derived as L or D. The left P in the production 3 is the head, and the right L|D is the body. For another example, the target grammar includes the production 4 LODOP.ADD_PRINT_TEXT”('(ARG(','ARG)*)?')' and the production 5 ARG->INT|FLOAT|STRING, where LODOP.ADD_PRINT_TEXT is the current word node to be matched; '('(ARG(','ARG)*)?')' is the target parameter to be matched; (','ARG)*)?' indicates that the target parameter can be 0 or more; and the production 5 indicates that the target parameter ARG can be derived as an integer, a string, or a floating-point type.

[0083] Specifically, the computer device takes the current word node as an edge node in the target syntax tree, the edge node being a node farthest from the root node and at the end when matching from bottom to top. The computer device searches the body corresponding to each of the plurality of productions for a production identical to the edge node, i.e., a target production matching the edge node, and takes the non-terminal in the head of the target production as the parent node of the edge node. For example, when the integer 10 is the edge node, the computer device determines production 1 as the target production, and D in production 1 as the parent node of 10.

[0084] Since the target syntax tree is composed of nodes at multiple levels, for each round of construction, the process of taking the parent node as a new edge node and returning to determining the target production matching the edge node from the plurality of productions is performed. For example, when D is the new edge node, the computer device determines production 3 as the target production, and P in production 3 as the parent node of D.

[0085] When the non-terminal is the root node, the round ends, at which time there is no matching production, and the computer device synthesizes all edge nodes to obtain a matching sub-result corresponding to the current word node, the matching sub-result representing a sub-structure tree constructed by the current word node. As shown in Figure 5 Figure 5 is a schematic diagram of the principle of constructing the target syntax tree. For example, the specification of the source statement ADD_PRINT_TEXT(intTop, intLeft, intWidth, intHeight, strContent) can obtain five parameters, and when the source statement edited by the user is LODOP.ADD_PRINT_TEXT(10, 10, 100, 100, "hello"), the computer device can determine the word type corresponding to each parameter and assign values to the corresponding parameters.

[0086] In this embodiment, the target grammar is used to construct the data stream into the target syntax tree from bottom to top, so that the source statement can be quickly recognized, and since the source statement only needs to edit a small number of parameters, the corresponding target syntax tree can be quickly constructed when the different printing functions are triggered multiple times, ensuring the efficiency of text printing. In addition, since the target grammar can be obtained by being predefined by the user, the flexibility of constructing different syntax trees is also improved.

[0087] ​In one of the embodiments, the computer device can encrypt the target syntax tree according to a preset encryption algorithm to obtain an encrypted syntax tree. The preset encryption algorithm can be, for example, an MD5 (Message-Digest Algorithm 5) encryption algorithm, a base64 encryption algorithm, or the like. The computer device can encrypt each node in the target syntax tree respectively to generate the encrypted syntax tree, or encrypt part of the nodes in the target syntax tree and combine the encrypted part of the nodes with the unencrypted nodes to form the encrypted target syntax tree. In this way, the security of compiling the target syntax tree can be ensured.

[0088] It should be understood that, although each step in the flowchart involved in the above embodiments is shown in sequence according to the arrow, these steps are not necessarily executed in the order indicated by the arrow. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other orders. Moreover, at least part of the steps in the flowchart involved in the above embodiments can include multiple steps or stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily sequential, but can be executed alternately or alternately with at least part of other steps or steps or stages in other steps.
