Based on the research, the disclosure provides a lecture typesetting method and device, electronic equipment and a storage medium, and the typesetting accuracy is high.
To facilitate understanding of the present embodiment, a method for typesetting a lecture disclosed in the embodiments of the present disclosure is first described in detail, and an execution subject of the method for typesetting a lecture provided in the embodiments of the present disclosure is generally a computer device with certain computing power, where the computer device includes: a terminal device, which may be a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, or a server or other processing device. In some possible implementations, the method of handout composition may be implemented by a processor calling computer readable instructions stored in a memory.
Referring to fig. 1, a flowchart of a method for setting lectures provided in the embodiment of the present disclosure is shown, where the method includes steps S101 to S104, where:
s101: acquiring a lecture file in a first document format to be typeset;
s102: based on the standard content model, standardizing the semantic file to obtain a standard file; the standard content model is used for uniformly describing the content and the style of the rich text documents in different document formats;
s103: obtaining a target typesetting system file based on the standard file and the target typesetting system configuration information;
s103: and typesetting the target typesetting system file to generate a lecture file in a second document format after typesetting.
In order to facilitate understanding of the method for composing handout provided by the embodiment of the present disclosure, first, a brief description is given to an application scenario of the method. The lecture typesetting method can be mainly applied to online education scenes, and can help teaching teachers typeset lecture files to be typeset into typeset high-printing-quality lecture files so that teaching teachers can give lessons conveniently. Here, the lecture file to be laid out may be a lecture file edited using an on-line lecture editing tool, and have a special data structure. The high-printing-quality lecture file can be a rendered PDF file, and the visualization effect is better.
The format of the lecture file to be typeset can be a first document format which is described by using an EasySync OT data structure of a collaborative protocol and is related to the content and the style of rich text, and the readability of the EasySync OT data structure is poor.
In order to better realize the typesetting of the lecture file, the lecture file with the first document format can be standardized to obtain a standard file, and the standard file not only can well describe the conversion relationship between the lecture file and other various files, but also can solve the problem of poor readability. Thus, after the standard file is configured by using the target typesetting system configuration information, the target typesetting system file can be obtained.
The target typesetting system file may be a file with a better typesetting performance, for example, a LaTeX file, so that after the target typesetting system file is typeset, a lecture file in the second document format after typesetting can be obtained. For example, in the case of a LaTeX file as the target layout system file, the lecture file of the second document format after layout here may be a PDF file. In a specific application, the final typesetting effect can be realized through a rendering technology, which is not described herein.
In the embodiment of the disclosure, the standardized processing for the lecture file can be realized based on the standard content model, and the standard content model is used for uniformly describing the content and the style of the rich text document in different document formats, that is, can be used as an intermediate model for converting the document formats, so that the universality and the expansibility of the content conversion service can be ensured, and the mutual conversion among the document formats can be realized.
The standard content model can be a standard model extracted from each document format, and can take into account each document format, so that the target typesetting system file can be conveniently and quickly obtained by utilizing the configuration information of the target typesetting system. It can be known that for the lecture file with the first document format with poor readability, the standardization processing under the constraint of high readability can be carried out, and then the typesetting operation aiming at the target typesetting system file with good typesetting characteristics can be realized, so that the obtained lecture file with the second document format greatly reduces the probability of losing and wrong typesetting contents, and the typesetting accuracy is higher.
The target typesetting system configuration information in the embodiment of the disclosure may be a related configuration command for the target typesetting system file. In a specific application, the corresponding configuration command may be selected based on different target typesetting system files. In consideration of the excellent characteristics of the LaTeX file in the layout level, the LaTeX file may be used as the target layout system file.
For the LaTeX file, a preset typesetting engine can be called to realize typesetting in the embodiment of the disclosure. In a specific application, the XeTeX typesetting engine can be used for compiling and rendering so as to support OpenType font technology and generate a PDF file.
The XeTex typesetting engine can be contained in a TeX Live software publishing suit, and publishing images in the TeX Live software publishing suit can be packaged in a service image. Therefore, the LaTeX file can be compiled into the PDF file by directly calling the XeTeX typesetting engine, and the PDF file is rendered on the client side to be displayed.
Considering the key role of the standard document generation for the subsequent typesetting, the following process for generating the standard document can be explained, which specifically includes the following steps:
analyzing a semantic file based on a predefined file analysis model to analyze first file data information matched with the file analysis model;
secondly, determining an analyzed file according to the analyzed first file data information and a file analysis model;
converting the analyzed file based on a predefined standard content model to obtain second file data information matched with the standard content model;
and step four, obtaining a standard file based on the obtained second file data information and the standard content model.
Here, considering that the readability of the lecture file with the first document format is poor, the lecture file may be first parsed by using a predefined file parsing model to parse the first file data information matching with the file parsing model, where the parsing may be parsing of the collaborative data structure EasySync OT of the lecture file to be typeset.
The file parsing model can be used to describe the contents and attributes of each block in a file paragraph and a paragraph, and can be understood as a framework model. Taking online education as an example, the first file data information analyzed here may be contents related to blocks, including special service metadata such as test questions and subject plug-ins owned by the online lecture, or attributes related to blocks, including data such as styles of test questions.
It should be noted that, for different educational disciplines, the specific pointing content of the corresponding document paragraph may be different. For example, in a mathematical subject, a document paragraph herein may point to a mathematical subject, which may include a subject, a subject stem, and the like, where the subject and the subject stem may respectively correspond to a block and have respective attributes, for example, the subject is a style of font four, and the subject stem is a style of picture; for another example, in a Chinese subject, a document paragraph herein may correspond to a paragraph of an article.
Here, the first file data series information is input to the file analysis model, so that the analyzed file can be determined. For the parsed file, embodiments of the present disclosure may convert the parsed file based on a standard content model. The standard content model is also understood to be a framework model describing a common document format. Similarly, here, the second file data information obtained by converting the parsed file may be input to the standard content model, so that the standard file may be determined.
The lecture typesetting method provided by the embodiment of the disclosure can generate a target typesetting system file based on the standard file. Under the condition that the LaTeX file is used as a target typesetting system file, the LaTeX file can be obtained according to the following steps:
reading each paragraph of a standard file in sequence; each paragraph includes at least one partition;
secondly, performing attribute analysis on each block in each read paragraph based on a preset attribute analyzer to determine the attribute of the block;
determining a LaTeX command matched with the attribute of each block based on the preset corresponding relation between each attribute and each LaTeX command;
and step four, obtaining a LaTeX file based on the LaTeX command matched with the attribute of each block.
In order to better implement batch modification based on attributes, the embodiments of the present disclosure provide a scheme for separately configuring the attributes and contents of the partitions with commands.
Here, the attribute analysis of each block may be implemented based on an attribute analyzer, and then the LaTeX command matching the attribute of the block is determined, and then the final LaTeX file is determined according to the inclusion relationship between the blocks and the paragraphs and the arrangement order between the paragraphs. The method is realized by the following steps:
step one, aiming at each block in each paragraph, binding a LaTeX command matched with the attribute of the block and the content of the block to obtain a LaTeX command line corresponding to the block;
step two, aiming at each paragraph, combining the LaTeX command lines corresponding to the blocks belonging to the paragraph to obtain the LaTeX command line corresponding to the paragraph;
and step three, combining the LaTeX command lines corresponding to the paragraphs according to the arrangement sequence of the paragraphs to obtain a LaTeX file.
Considering that in the actual writing process, LaTeX may refer to a large number of macro packages and custom macro commands, and often needs to modify the style definition used to realize the setting of the style required for typesetting. Thus, the LaTeX command herein may be primarily a predefined macro command. That is, each attribute may point to a macro command, and after the corresponding macro command is determined, the content of the corresponding block may be bound to the macro command, so as to obtain a LaTeX command line corresponding to the block. Therefore, under the condition that the style is required to be modified subsequently, only the pre-definition of the macro command needs to be modified, and the time for typesetting and editing is greatly saved.
The composition operation in the disclosed embodiment may include a modification operation on the LaTeX file. Here, an editing window may be provided at the client, and when it is determined that an editing instruction for the LaTeX file is received by the client, the LaTeX file is modified based on the editing instruction to obtain a modified LaTeX file, and then the modified LaTeX file is typeset to generate a typeset PDF file.
The editing instruction may be determined by receiving a style editing instruction of a macro command for matching an attribute of any partition included in the LaTeX file, that is, by modifying the macro command at the client to select a style to be applied, or by receiving a content editing instruction for any partition included in the LaTeX file, that is, by modifying the content of the partition at the client to determine the modified content.
Any of the above editing instructions can be initiated by an online LaTeX editor set on the client, mainly for the typesetter to perform better editing operations.
In order to facilitate understanding of the above interaction process between the server and the client, the following can be further described with reference to fig. 2.
As shown in fig. 2, an editor interface is presented on the client. On the current editor interface, a user can initiate an editing instruction by using a LaTeX editor, so that relevant modification operation pointing to a specific LaTeX file can be carried out on the server side based on typesetting item management. The modification can be the modification of the content of the handout and the modification of the format of the handout.
Regardless of the modification manner, in the embodiment of the present disclosure, the LaTeX file may be compiled at the server, and the PDF file obtained by compiling may be rendered on an editor interface of the client.
The method for setting handout provided by the embodiment of the disclosure can also realize the conversion between different files by using the standard file so as to meet the file conversion requirements of users. Here, the method may include obtaining a standard file corresponding to the target layout system file when it is determined that a conversion instruction pointing to another target layout system file from the target layout system file is received, and obtaining another layout system file based on the standard file and the configuration information of the other layout system.
The other typesetting system files may be HTML files, Word files, or other system files, which is not limited in this disclosure.
It will be understood by those skilled in the art that in the method of the present invention, the order of writing the steps does not imply a strict order of execution and any limitations on the implementation, and the specific order of execution of the steps should be determined by their function and possible inherent logic.
Based on the same inventive concept, the embodiment of the present disclosure further provides a device for lecture material composition corresponding to the method for lecture material composition, and because the principle of solving the problem of the device in the embodiment of the present disclosure is similar to the method for lecture material composition described above in the embodiment of the present disclosure, the implementation of the device may refer to the implementation of the method, and repeated details are not described.
