specific Embodiment 1

[0037] Such as Figure 1a and Figure 1b As shown, the embodiment of the present invention provides a LaTeX-based formula editing method, including:

[0038] Input step S101, receiving the data entered into the editor by the editor;

[0039] Code obtaining step S102, obtaining the LaTeX code corresponding to the data in the current editor;

[0040] Rendering step S103, rendering the acquired LaTeX code, generating and displaying a formula in a normal writing format;

[0041] Inquiry step S104, ask the editor whether to finish editing; when the editor chooses yes, output the LaTeX code rendered last time as the final code; when the editor chooses no, return to input step S101;

[0042] In the formula generation step S105, according to the final code, a target formula text in a normal writing format that can be directly edited and copied is generated.

[0043] The embodiment of the present invention applies LaTeX typesetting technology, and on this basis, combined with webpag...

specific Embodiment 2

[0049] Such as figure 2 As shown, the embodiment of the present invention provides a LaTeX-based formula editor, including:

[0050] The input module 201 is used to perform the input step: receiving the data entered into the editor by the editor;

[0051]The code acquisition module 202 is used to perform the code acquisition step: acquire the LaTeX code corresponding to the data in the current editor;

[0052] The rendering module 203 is used to perform a rendering step: rendering the obtained LaTeX code, generating and displaying a formula in a normal writing format;

[0053] Inquiry module 204 is used to perform the inquiry step: ask the editor whether to finish editing; when the editor selects yes, output the LaTeX code of the latest rendering as the final code; when the editor selects no, return to the input step;

[0054] The formula generating module 205 is configured to execute the formula generating step: according to the final code, generate the target formula text...

Abstract

The invention provides a LaTex-based formula editing method and a formula editor. By applying the LaTex typesetting technology, on the basis, PHP, AJAX and other webpage developing technologies are combined for obtaining the formula editor capable of being opened under a browser. A formula symbol clicked by a compiler can be obtained in real time, LaTex codes and the normal writing form can be previewed, after the compiler completes edition and submission, the normal writing form can be shown, the copied target formula text can be directly edited, and the formula editing efficiency of the compiler can be improved. The invention further provides a checking and approving function based on preset checking and approving rules, and the compiler can be reminded to avoid some common errors. The invention further provides a synchronous function, data in the editor can be saved at any time, and the phenomenon that data loss in the editor is caused due to equipment outage is avoided.

Description

technical field [0001] The invention relates to the technical field of formula-based editing, in particular to a formula editing method and a formula editor based on LaTeX. Background technique [0002] In the process of study and life, we often deal with texts with complex formats such as formulas. Due to its complex format, it is difficult to input or edit it with general text input editing tools. In the existing mode, there are two common ways to input and edit formulas: one is to display the formula in an abnormal writing state (for example, one-half is often written as 1 / 2 in many texts), and the other is to display the formula Convert it to a picture after editing with a third-party plug-in (such as the formula editor of Microsoft Word). Either way, the problem of displaying and editing the normal writing format of the formula cannot be well solved. Contents of the invention [0003] LaTeX (LATEX, transliterated "La Taihe") is a typesetting system based on TEX, de...
