Description

Markdown grammar extension-based text editing method and system

Technical Field

The invention relates to the technical field of software engineering, in particular to a text editing method and system based on markdown grammar extension.

Background

Markdown is a lightweight markup language that allows people to compose documents using a plain text format that is easy to read and write. It has a set of fixed grammar rules. It is difficult to write a more personalized document in Markdown language.

At present, a plurality of markdown editors and readers are available on the market, but the following problems exist:

1. lack of functionality for personalized grammar configuration;

2. meanwhile, the ability of personalized configuration of reader styles is lacked;

3. the problem of very unsmooth reading of large markdown texts.

The invention provides a text editing method and system based on markdown grammar extension, which aim to overcome the defects of the prior art.

In one aspect, the present invention provides a method for editing a text based on markdown syntax extension, the method comprising the following steps:

s1: reading a markdown text file uploaded by a user, and converting the markdown text file into a markdown plain text;

s2: according to rules configured by a user in a self-defined manner and rules of a product used at present, generating a grammar rule for processing the markdown plain text correspondingly by utilizing each rule, and compiling each grammar rule with a corresponding function to generate a corresponding function for analyzing the markdown plain text by utilizing the grammar rule when the function is operated;

s3: writing css according to a user-defined configuration pattern, storing the pattern in a css mode, and loading the css to a header head of html to realize configuration of the grammar rule when analyzing the markdown plain text, wherein the pattern is defined by a user according to the user-defined configuration rule;

s4: and analyzing the markdown plain text in sequence based on the grammar rule corresponding to the function in a mode of operating the functions one by one, obtaining an analyzed text after operating all the functions, and converting the analyzed text into an html text.

The method reads the markdown text, analyzes the modified text by the chain analysis algorithm according to the self-defined grammar rule and the rule by rule, converts the modified text into the html text which can be read by the browser, and loads the user-defined style at the same time, thereby finally realizing grammar expansion and style personalized configuration.

In a specific embodiment, the api of the filereader is used when reading the markdown text file uploaded by the user.

In a particular embodiment, the style specifically includes a grammar extension and a style personalization.

In a specific embodiment, before the markdown plain text is sequentially analyzed based on the grammar rule corresponding to the function by operating the functions one by one, paging the markdown plain text is further performed, and the specific steps include:

sequentially reading L lines of texts in the markdown plain text, taking the L lines of texts as a page of text to be analyzed after each L line of texts is read, executing the step in S4 on the page of text to be analyzed, and reading the next L lines of texts;

and L is the number of lines occupied by each page of text to be analyzed, and L is the screen height/the fixed occupied height of each line. The method for asynchronously analyzing the text by paging avoids the problem of jamming caused by analyzing all markdowns at one time.

In a specific embodiment, when the user jumps to the nth to-be-analyzed text during reading the markdown plain text, the step in S4 is performed on the nth to-be-analyzed text, where the nth to-be-analyzed text is specifically the text from the (N-1) th line to the nth line in the markdown plain text.

In a specific embodiment, the S4 further includes:

when the function which is currently operated is found to be abnormal during analysis, the rule which is configured by the user self-definition and corresponds to the function is positioned and fed back, and meanwhile, the function which is abnormal is skipped to continuously operate the next function. When any rule is abnormal, the user can skip the rule, continue to analyze downwards and prompt the user that a certain custom rule is abnormal in writing.

Through the chain analysis of the S4, any rule can be formed by combining any plurality of sub-rules in a chain mode, and therefore the rule expandability is improved; a plurality of rules can be combined and sequenced with each other, so that a special translation effect is achieved; when a user customizes the rule, if the rule is wrongly written, the chain analysis can accurately position the rule with the exception, so that the application of other rules is not influenced, and the fault tolerance of the product is improved.

In a specific embodiment, the user-defined rule includes a plurality of sub-rules, and the plurality of sub-rules are used to be executed in sequence when the function is executed.

In a specific embodiment, the method is used in a markdown reader to facilitate reading.

S202: and correspondingly generating a grammar rule for processing the markdown plain text by utilizing each rule according to the rule configured by the user and the rule carried by the product used at present, and compiling each grammar rule with the function corresponding to the grammar rule to generate a corresponding function for analyzing the markdown plain text by utilizing the grammar rule when the function is operated.

In a specific embodiment, the following function (denoted F) is used as a carrier of the grammar rules, where T denotes markdown plain text generated in S201:

function F(T){

1. matching according to grammatical rules

2. Conversion to target text T0

3. Return converted text TO

}

The function F is specifically described below by way of example:

if the user defines a grammar rule F0, matching ([ B ] arbitrary markwon text) in the markdown grammar, which indicates that text beginning with [ B ] as a line is uniformly converted into bold font < B > arbitrary markwon text. Then the grammar rule F0 corresponds to the writing of the function F0 as follows:

it should be appreciated that these rules can be custom configured by the user, or can be obtained by loading off-the-shelf rules.

S203: and compiling cs according to a user-defined configuration pattern, storing the pattern in the cs, and loading the cs to a header of html (hypertext markup language) when analyzing the markdown plain text so as to configure the grammar rule, wherein the pattern is defined by a user according to the user-defined configuration rule.

S204: and analyzing the markdown plain text in sequence based on the grammar rule corresponding to the function in a mode of operating the functions one by one, obtaining an analyzed text after operating all the functions, and converting the analyzed text into an html text.

The following illustrates the chain analysis in step S204:

for example, the existing product has its own rules F1, F2, F3 and user-defined rules Fa, Fb, Fc, then the parsing method is as follows:

t ═ markdwon plain text'

R＝F1(T)

R＝F2(R)

R＝F3(R)

R＝Fa(R)

R＝Fb(R)

R＝Fc(R)

……

And after the analysis is finished, R is the text after the final analysis.

and L is the number of lines occupied by each page of text to be analyzed, and L is the screen height/the fixed occupied height of each line.

In a specific embodiment, the S204 further includes:

when the function which is currently operated is found to be abnormal during analysis, the rule which is configured by the user self-definition and corresponds to the function is positioned and fed back, and meanwhile, the function which is abnormal is skipped to continuously operate the next function.
