Function JsonEdit 

pub fn JsonEdit(
    File: &Path,
    Product: &str,
    Id: &str,
    Version: &str,
    SidecarPath: Option<&str>,
) -> Result<bool, Error>

Dynamically modifies fields in a tauri.conf.json or tauri.conf.json5 file, including the sidecar path.

This function updates the following fields in the Tauri configuration:

• version - The application version
• productName - The product name displayed to users
• identifier - The bundle identifier (reverse domain format)
• bundle.externalBin - Adds the sidecar binary path if provided

The function automatically detects and handles both JSON and JSON5 formats, ensuring compatibility with different Tauri configuration styles.

Parameters

• File - Path to the Tauri configuration file
• Product - The product name to set (displayed to users)
• Id - The bundle identifier to set (reverse domain format)
• Version - The version string to set
• SidecarPath - Optional path to the sidecar binary to bundle

Returns

Returns a Result<bool> indicating:

• Ok(true) - The file was modified and saved
• Ok(false) - No changes were needed (all values already match)
• Err(BuildError) - An error occurred during modification

Errors

• BuildError::Io - If the file cannot be read or written
• BuildError::Json - If JSON parsing or serialization fails
• BuildError::Jsonfive - If JSON5 parsing fails
• BuildError::Utf - If UTF-8 conversion fails

Behavior

• Only modifies fields that don’t match the specified values
• Creates nested structures (bundle, externalBin) as needed
• Writes output with tab indentation for human-readable formatting
• Logs configuration changes at INFO level

JSON5 Support

JSON5 is a superset of JSON that allows:

• Trailing commas
• Unquoted property names
• Comments
• Multi-line strings

The function automatically detects JSON5 files by their .json5 extension and uses the appropriate parser.

Example

use crate::Maintain::Source::Build::JsonEdit;
let path = PathBuf::from("tauri.conf.json");
let modified = JsonEdit(
&path,
"Debug_Mountain",
"land.editor.binary.debug.mountain",
"1.0.0",
Some("Binary/node")
)?;
