Explanation
This code is a simple YAML formatter. It takes YAML files as input and outputs the formatted version of the files.
Main Function main()
- The program first defines a flag
-indent
to control the indentation level, defaulting to 2 spaces. - It parses the command-line arguments to get the input file paths.
- It iterates through each input file:
- It reads the YAML content from the file using
os.ReadFile
. - It parses the YAML content into a
yaml.Node
usingfetchYaml
. - It opens the same file for writing (truncating the existing content) using
os.OpenFile
. - It formats and writes the YAML content to the file using
streamYaml
. - Error handling is done in each step by printing error messages to stderr if any error occurs.
fetchYaml()
- It takes the YAML content as a byte slice.
- It unmarshals the content into a
yaml.Node
usingyaml.Unmarshal
. - If there’s an error during unmarshalling, it returns an error.
- Otherwise, it returns the parsed
yaml.Node
.
streamYaml()
- It takes the output writer, indentation level, and the parsed YAML node as input.
- It creates a new
yaml.Encoder
with the provided writer. - It sets the indentation level for the encoder.
- It encodes the YAML node using the encoder’s
Encode
method. - If there’s an error during encoding, it returns an error.
- It closes the encoder using
encoder.Close()
.
Overall
The code demonstrates a basic YAML formatter using the gopkg.in/yaml.v3
package. It reads YAML from files, parses the content, formats it with indentation, and writes the formatted content back to the same files.
