Description
Technical Field
[0001] The present invention relates to the technical field of YAML configuration files, and specifically, to a method and tool for processing YAML configuration files. Background Art
[0002] Existing YAML editors usually only provide text editing functions and do not provide a visual interface to help users better understand and edit complex YAML structures. This makes it difficult to manage and modify YAML files in large projects. Additionally, some YAML editors and processors may have problems when parsing and validating YAML files, resulting in incorrect configurations being applied to the system. The lack of error checking and prompting functions makes these problems difficult to discover and solve.
[0003] Go is an open-source programming language developed by Google in 2007 and designed specifically for high-performance distributed systems. It combines features such as static typing, garbage collection, and concurrency models (goroutines and channels), providing efficient system programming capabilities while also simplifying the complexity of concurrent programming.
[0004] YAML (YAML Ain't Markup Language) is a human-readable data serialization format commonly used in scenarios such as configuration files and data exchange. Compared with JSON, YAML supports more data structures, such as comments, anchors, aliases, etc., and the format is more compact and readable.
[0005] Based on the simplicity and high performance of the Go language, combined with the readability of the YAML data format, as well as the powerful and flexible logging and file operation capabilities, this article designs an efficient and easy-to-use method and tool for processing YAML configuration files, allowing users to automatically modify YAML while retaining key information such as the original format order and comments. Summary of the Invention
[0006] The present invention aims at the requirements and deficiencies of the current technological development and provides a method and tool for processing YAML configuration files.
[0007] In a first aspect, the present invention provides a method for processing YAML configuration files, and the technical solution adopted to solve the above technical problems is as follows:
[0008] A method for processing YAML configuration files includes the following steps:
[0009] S1. Load the YAML configuration file through the os standard library and parse it into the source yaml.Node;
[0010] S2. Parse the data in the source yaml.Node into a map structure through the Decode method, and preserve the order of the original format.
[0011] S3. Directly perform addition, deletion, and modification operations on the data parsed into a map structure.
[0012] S4. Create a target yaml.Node to store the modified key-value pairs and annotation information; loop through each node in the source yaml.Node and compare it with each node in the target yaml.Node to determine the data type and key-value information: if they are all the same, copy the annotation information in the source yaml.Node to the target yaml.Node; if the data type is map, recursively process the node and its child nodes until all data is processed.
[0013] S5. Use the yaml.Encode method to compile the target yaml.Node into a bytes byte stream, and then create a write stream to write the bytes byte stream into the corresponding yaml configuration file.
[0014] Optionally, to execute step S1, first use the os.Open function to open the yaml configuration file, then use the Go language's ioutil.ReadAll function to read the content of the yaml configuration file, and then use the yaml.Unmarshal method to parse the content of the yaml configuration file into the source yaml.Node.
[0015] Preferably, a yaml.Node is a linked list structure that contains the current key and value information, as well as a pointer to the next data node, and also contains the annotation information around the current key.
[0016] Optionally, the specific operations involved in step S2 are as follows:
[0017] Import the Go language's encoding / yaml package.
[0018] Create an empty variable of type yaml.MapSlice to store the parsed data.
[0019] Use the yaml.Unmarshal method to parse the data in the source yaml.Node into the created yaml.MapSlice variable.
[0020] Use fmt.Println to output the parsed yaml.MapSlice. yaml.MapSlice is a slice containing key-value pairs, and yaml.MapSlice stores elements in the order of the YAML file.
[0021] Optionally, perform step S3 to directly perform addition, deletion, and modification operations on the data parsed into a map structure. Among them, the newly added keys are added through assignment statements, the deleted keys are removed from the map through the delete method, and the modified keys are assigned through the specified keys to complete the modification operation.
[0022] In a second aspect, the present invention provides a processing tool for yaml configuration files. The technical solutions adopted to solve the above technical problems are as follows:
[0023] A processing tool for yaml configuration files, which includes:
[0024] A loading and parsing module, used to load a yaml configuration file through the os standard library and parse it into the source yaml.Node;
[0025] A parsing and processing module, used to parse the data in the source yaml.Node into a map structure through the Decode method and retain the order of the original format;
[0026] A data processing module, used to directly perform addition, deletion, and modification operations on the data parsed into a map structure;
[0027] A creation module, used to create a target yaml.Node to store the modified key-value pairs and annotation information;
[0028] A traversing and comparing module, used to loop through each node in the source yaml.Node and compare it with each node of the target yaml.Node;
[0029] A judgment and processing module, used to judge the data type and key-value information according to the comparison result output by the traversing and comparing module, and copy the annotation information in the source yaml.Node to the target yaml.Node when both the data type and key-value information are the same, and recursively process the node and its sub-nodes when the data type is map until all data processing is completed;
[0030] A compilation and writing module, used to compile the target yaml.Node into a bytes byte stream using the yaml.Encode method and create a writing stream to write the bytes byte stream into the corresponding yaml configuration file.
[0031] Optionally, the involved loading and parsing module loads the yaml configuration file through the os standard library and parses it into the source yaml.Node. The specific process is as follows:
[0032] First, use the os.Open function to open the YAML configuration file. Then, use the ioutil.ReadAll function in Go language to read the content of the YAML configuration file. After that, use the yaml.Unmarshal method to parse the content of the YAML configuration file into the source yaml.Node.
[0033] Preferably, the involved yaml.Node is a linked list structure, which contains the current key and value information, as well as a pointer to the next data node. At the same time, it also contains the annotation information around the current key.
[0034] Optionally, the involved parsing and processing module parses the data in the source yaml.Node into a map structure through the Decode method and retains the order of the original format. The specific process is as follows:

[0039] Optionally, the involved data processing module directly performs addition, deletion, and modification operations on the data parsed into a map structure. Among them, the newly added key is added through an assignment statement, the deleted key is removed from the map through the delete method, and the modified key is completed by assigning a value to the specified key.

[0041] 1. The present invention aims to simplify the reading, writing, and merging operations of YAML format configuration files, while maintaining annotation and structural integrity, improving the flexibility and maintainability of configuration management, significantly improving development and operation and maintenance efficiency, and reducing problems caused by manual configuration errors;
[0042] 2. The present invention realizes flexible processing of YAML files through the Go language and its standard library, allowing users to automatically modify YAML while retaining key information such as the original format order and comments.

[0045] FIG. Figure 2 is a block diagram of module connections according to the second embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0046] To make the technical solutions, technical problems to be solved, and technical effects of the present invention clearer and more understandable, the following describes the technical solutions of the present invention clearly and completely in conjunction with specific embodiments.
[0047] The following is an explanation of the English words involved in the embodiments:
[0048] Go language (Golang): Go is an open-source programming language developed by Google in 2007 and designed specifically for high-performance distributed systems. It combines features such as static typing, garbage collection, and concurrency models (goroutines and channels), providing efficient system programming capabilities while also simplifying the complexity of concurrent programming.
[0049] YAML (YAML Ain't Markup Language): YAML is a human-readable data serialization format commonly used in scenarios such as configuration files and data exchange. Compared with JSON, YAML supports more data structures, such as comments, anchors, aliases, etc., and the format is more compact and readable.
[0050] Configuration file: For each project, a method is needed to define different global configuration items, which is usually achieved by means of a configuration file. Nowadays, configuration files usually choose YAML or JSON formats as the configuration standard.
[0051] Standard library: bufio provides buffered I / O to improve file reading and writing performance; bytes provides byte-level operations, such as byte buffers, for processing binary data; os involves functions for operating system interaction, such as file reading and writing, process signal handling, etc.
[0052] Yaml.Node: A linked list data structure provided by the Go language standard library, used to store yaml data for subsequent parsing and mapping of the source file format.
[0053] Example 1:
[0054] Combined with the attached Figure 1 , this example proposes a method for processing yaml configuration files, which includes the following steps:
[0055] S1. Load the yaml configuration file through the os standard library and parse it into the source yaml.Node. The specific operations are as follows:
[0056] First, use the os.Open function to open the yaml configuration file, then use the ioutil.ReadAll function of the Go language to read the content of the yaml configuration file, and then use the yaml.Unmarshal method to parse the content of the yaml configuration file into the source yaml.Node.
[0057] yaml.Node is a linked list structure that contains the current key and value information, as well as a pointer to the next data node. It also contains the comment information around the current key.
[0058] S2. Through the Decode method, parse the data in the source yaml.Node into a map structure and retain the order of the original format. The specific operations include the following:
[0059] Import the encoding / yaml package of the Go language;
[0060] Create an empty variable of the yaml.MapSlice type to store the parsed data;
[0061] Use the yaml.Unmarshal method to parse the data in the source yaml.Node into the created yaml.MapSlice variable;
[0062] Use fmt.Println to output the parsed yaml.MapSlice. yaml.MapSlice is a slice containing key-value pairs, and yaml.MapSlice will store elements in the order of the YAML file.
[0063] S3. For the data parsed into a map structure, directly perform addition, deletion, and modification operations. Among them, the newly added key is added through an assignment statement, the deleted key is removed from the map through the delete method, and the modified key is assigned through the specified key to complete the modification operation.
[0064] S4. Create a target yaml.Node to store the modified key-value pairs and annotation information; loop through each node in the source yaml.Node and compare it with each node in the target yaml.Node to determine the data type and key-value information: if they are all the same, copy the annotation information in the source yaml.Node to the target yaml.Node; if the data type is map, recursively process the node and its child nodes until all data is processed. This process specifically involves finding or creating the corresponding key in the target yaml.Node and copying the child nodes in the source yaml.Node to the target yaml.Node.
[0065] It should be added that: if only one of the data type and key-value information is the same or both are different, a new node needs to be created in the target yaml.Node to store the information of the corresponding node in the source yaml.Node. The specific steps are as follows: check the data type of the current node in the source yaml.Node. a) If the data type is not map (i.e., not a collection of key-value pairs), directly copy the node to the target yaml.Node, including the key, value, and annotation information of the node. b) If the data type is map, recursively process the node and its child nodes until all nodes in the source yaml.Node are processed.
[0066] S5. Use the yaml.Encode method to compile the target yaml.Node into a bytes byte stream, and then create a write stream to write the bytes byte stream into the corresponding yaml configuration file.
[0067] It should be added that this embodiment also introduces the logrus logging library to record error information. When errors occur during file operations, yaml parsing, or serialization, the error information will be detailedly recorded through the log, and the program will be terminated in case of serious errors, ensuring the timely discovery and handling of errors.
[0068] Logrus: is a popular Go logging library that provides a structured logging method, supports custom output formats, levels, and hooks, making the log information richer and easier to analyze. In the above code, logrus is used to record error information to help developers quickly locate and solve problems.
[0069] Embodiment 2:
[0070] Combined with the attached Figure 2 , this embodiment proposes a processing tool for yaml configuration files, which includes:
[0071] A loading and parsing module, used to load a YAML configuration file through the os standard library and parse it into the source yaml.Node;
[0072] A parsing and processing module, used to parse the data in the source yaml.Node into a map structure through the Decode method and retain the order of the original format;
[0073] A data processing module, used to directly perform addition, deletion, and modification operations on the data parsed into a map structure. Among them, newly added keys are added through assignment statements, deleted keys are removed from the map through the delete method, and modified keys are assigned through the specified keys to complete the modification operation;
[0074] A creation module, used to create a target yaml.Node to store the modified key-value pairs and annotation information;
[0075] A traversing and comparing module, used to loop through each node in the source yaml.Node and compare it with each node in the target yaml.Node;
[0076] A judgment and processing module, used to judge the data type and key-value information according to the comparison result output by the traversing and comparing module, and copy the annotation information in the source yaml.Node to the target yaml.Node when both the data type and key-value information are the same. When the data type is map, recursively process the node and its child nodes until all data is processed;
[0077] A compilation and writing module, used to compile the target yaml.Node into a bytes byte stream using the yaml.Encode method and create a writing stream to write the bytes byte stream into the corresponding YAML configuration file.
[0078] In this embodiment, the involved loading and parsing module loads the YAML configuration file through the os standard library and parses it into the source yaml.Node. The specific process is as follows:
[0079] First, use the os.Open function to open the YAML configuration file, then use the ioutil.ReadAll function in Go language to read the content of the YAML configuration file, and then use the yaml.Unmarshal method to parse the content of the YAML configuration file into the source yaml.Node.
[0080] yaml.Node is a linked list structure, containing the current key key and value value information, as well as a pointer to the next data node, and also containing the annotation information around the current key.
[0081] In this embodiment, the involved parsing and processing module parses the data in the source yaml.Node into a map structure through the Decode method and preserves the order of the original format. The specific process is as follows:
[0082] Import the encoding / yaml package of the Go language;
[0083] Create an empty variable of type yaml.MapSlice to store the parsed data;
[0084] Use the yaml.Unmarshal method to parse the data in the source yaml.Node into the created yaml.MapSlice variable;
[0085] Use fmt.Println to output the parsed yaml.MapSlice. yaml.MapSlice is a slice containing key-value pairs, and yaml.MapSlice stores elements in the order of the YAML file.
[0086] It should be added that: the judgment processing module judges the data type and key-value information according to the comparison result output by the traversal and comparison module. If only one of the data type and key-value information is the same or both are different, a new node needs to be created in the target yaml.Node to store the information of the corresponding node in the source yaml.Node. The specific steps are as follows: Check the data type of the current node in the source yaml.Node. a) If the data type is not map (i.e., not a set of key-value pairs), directly copy the node to the target yaml.Node, which includes the key, value, and comment information of the node. b) If the data type is map, the node and its child nodes need to be processed recursively until all nodes in the source yaml.Node are processed.
[0087] It should be added that this embodiment also introduces the logrus logging library to record error information. When an error occurs during file operation, yaml parsing, or serialization, the error information will be detailedly recorded through the log, and the program will be terminated in case of a serious error, ensuring the timely discovery and handling of errors.
[0088] Logrus: is a popular Go logging library that provides a structured logging method, supports custom output formats, levels, and hooks, making the log information richer and easier to analyze. In the above code, logrus is used to record error information to help developers quickly locate and solve problems.
[0089] In summary, by using the method and tool for processing a YAML configuration file of the present invention, it aims to simplify the reading, writing, and merging operations of YAML format configuration files, while maintaining comment and structural integrity, enhancing the flexibility and maintainability of configuration management, and can significantly improve development and operation and maintenance efficiency, and reduce problems caused by manual configuration errors.
[0090] The above specific application examples have elaborated in detail the principle and implementation manner of the present invention. These examples are only used to help understand the core technical content of the present invention. Based on the above specific embodiments of the present invention, any improvements and modifications made by those skilled in the art of this technical field without departing from the principle of the present invention shall fall within the scope of patent protection of the present invention.
