In -depth analysis of the technical principles of the MINIMATCH framework in the Java class library Minimatch is a Java class library for matching and filtering file paths. It provides a powerful mode matching and filtering function.This article will explore the technical principles of the Minimatch framework to explain how it achieves the matching and screening of the file path. 1. What is Minimatch? MINIMATCH is a Java class library developed by the ISAAC Research Institute. It matches and screens the file path according to the path mode.This framework uses simple allocation and regular expression syntax, which can be used to process complex path matching needs.Minimatch can easily implement file filtering, searching, and screening function. 2. MINIMATCH's working principle The working principle of Minimatch can be divided into the following steps: a. Analysis mode: First, minimatch will analyze the input mode and convert it to a regular expression of the underlying layer.It supports the compatriots (such as "*" and "?") And regular expression syntax, which can be used to match the specific character or character sequence in the matching path. b. Construct a path matcher: Once the mode is analyzed, Minimatch will build a path matching device.The matching device can match and screen the path according to the predetermined mode.The path matching device converts the mode to an internal state machine so that the matching operation can be performed when traversing the path. c. Application Filter: When the road matching device is constructed, Minimatch will apply the matching device to the target path collection.MINIMATCH can find the path that matches the mode by iteration and perform the matching operation on the matching device. d. Return the matching result: Finally, the minimatch will return the collection of the path matching the mode.These paths can be processed further as needed, such as file operations, printing, etc. 3. Example of the use of minimatch Below is a simple example, demonstrating how to match and screen the file path with Minimatch: import io.minimatch.Minimatch; public class MinimatchExample { public static void main(String[] args) { // Create a minimatch instance Minimatch minimatch = new Minimatch("src/**/*.java"); // Get all the Java files that match the mode in the current directory String[] matches = minimatch.filter(".", true); // Printing results for (String match : matches) { System.out.println(match); } } } In the above examples, we first created a Minimatch instance to match all Java files with the "SRC" directory.Then, we use the `Filter` method to match the path in the current directory, and pass the second parameter` true` to indicate the recursively matching the child directory.Finally, we print all file paths that match the pattern. Summarize: This article analyzes the technical principles of the Minimatch framework in the Java library.The core principle of Minimatch is to analyze the mode, build a path matching device, apply the filter, and return the matching results.By using Minimatch, we can easily implement the mode matching and screening operation of the file path, and can be further processed as needed.It is hoped that readers will have a deeper understanding of the MINIMATCH framework through this article so that it can be better applied to actual development.
