How to Expand Truncated Variable Values in VSCode Debug Mode for Go?

Expanding Variable Values in VSCode Debug Mode

While debugging in Go, encountering truncated variable values represented as "..." can be frustrating. This problem arises when variable values exceed VSCode's default display limit.

To resolve this issue and display the entire value, you can modify the settings for the delve debugger, which is integrated into VSCode. Navigate to your settings.json file. Under "go.delveConfig," locate the "maxStringLen" parameter. This parameter controls the maximum string length displayed in the debugger.

Set "maxStringLen" to a higher value. However, it's important not to set this value too high, as it can significantly slow down the debugger. Other parameters, such as "maxArrayValues" and "maxStructFields," can also be adjusted to increase the amount of data displayed in the debugger.

An example of modified delve configuration settings is provided below:

"go.delveConfig": {
"dlvLoadConfig": {
"maxStringLen": 1000,
"maxArrayValues": 1000,
"maxStructFields": -1
}
}

By configuring these settings, you can fully view the values of variables while debugging in Go in VSCode. Keep in mind that adjusting these values too high may impact debugger performance, so it's recommended to optimize these settings for your specific debugging needs.
