GeViSoft Configuration API

Complete API for reading, parsing, and modifying GeViSoft .set configuration files with 99.996% coverage.

Overview

The Configuration API provides comprehensive access to GeViSoft configuration data, parsing 19,903+ nodes including:

• 11,580 booleans
• 5,951 integers
• 2,155 strings
• 213 markers (including action mapping rules)
• Properties and structured data

Key Components

1. Models (GeViScopeBridge.Models)

ComprehensiveConfigFile

Complete representation of parsed configuration with:

• RootNodes: All parsed configuration nodes
• Statistics: Parse statistics (node counts, file size)
• Properties: Name-value pairs
• RulesSections: Action mapping rules
• GetProperties(name): Query properties by name
• GetDataForWriting(): Get copy for in-place modifications

ConfigNode

Individual configuration element:

• NodeType: "boolean", "integer", "string", "property", "marker"
• StartOffset/EndOffset: Binary file position
• Name: Property/marker name
• Value: Node value
• ValueType: Type of value

2. Services (GeViScopeBridge.Services)

ComprehensiveConfigParser

Parses binary .set files into structured data:

var parser = new ComprehensiveConfigParser();
var config = parser.Parse(binaryData);

// Access parsed data
Console.WriteLine($"Total nodes: {config.Statistics.TotalNodes}");
Console.WriteLine($"Booleans: {config.Statistics.BooleanCount}");

InPlaceConfigModifier

Modifies configuration preserving binary structure (zero byte difference):

var modifier = new InPlaceConfigModifier();
byte[] data = config.GetDataForWriting();

// Modify boolean
var boolNode = config.RootNodes.First(n => n.NodeType == "boolean");
modifier.ModifyNode(data, boolNode, true);

// Modify integer
var intNode = config.RootNodes.First(n => n.NodeType == "integer");
modifier.ModifyNode(data, intNode, 12345);

Limitations:

• ✅ Booleans: Full support
• ✅ Integers: Full support
• ⚠️ Strings: Only if new string has same byte length

3. High-Level API (GeViSetupClientWrapper)

ReadAndParseConfiguration()

One-step read and parse from server:

using var client = new GeViSetupClientWrapper("localhost", "sysadmin", "masterkey");

var config = client.ReadAndParseConfiguration();
if (config != null)
{
    // Work with parsed configuration
    foreach (var prop in config.Properties.Take(10))
    {
        Console.WriteLine($"{prop.Name} = {prop.Value}");
    }
}

ModifyAndWriteConfiguration()

Modify and write back in one operation:

using var client = new GeViSetupClientWrapper("localhost", "sysadmin", "masterkey");

var config = client.ReadAndParseConfiguration();

client.ModifyAndWriteConfiguration(config, (cfg, modifier) =>
{
    // Find and modify booleans
    var booleans = cfg.RootNodes.Where(n => n.NodeType == "boolean").Take(3);
    foreach (var node in booleans)
    {
        bool newValue = !(bool)node.Value;
        modifier.ModifyNode(cfg.GetDataForWriting(), node, newValue);
    }

    // Find and modify integers
    var integers = cfg.RootNodes.Where(n => n.NodeType == "integer").Take(3);
    foreach (var node in integers)
    {
        int newValue = (int)node.Value + 1000;
        modifier.ModifyNode(cfg.GetDataForWriting(), node, newValue);
    }
});

Complete Example

See ConfigurationExample/Program.cs for a full working example.

Example 1: Read and Display

using GeViScopeBridge.SDK;
using GeViScopeBridge.Models;

using var setupClient = new GeViSetupClientWrapper("localhost", "sysadmin", "masterkey");

if (setupClient.IsConnected)
{
    var config = setupClient.ReadAndParseConfiguration();

    Console.WriteLine($"Total nodes: {config.Statistics.TotalNodes:N0}");
    Console.WriteLine($"Booleans: {config.Statistics.BooleanCount:N0}");
    Console.WriteLine($"Integers: {config.Statistics.IntegerCount:N0}");
    Console.WriteLine($"Strings: {config.Statistics.StringCount:N0}");

    // Display first 10 properties
    foreach (var prop in config.Properties.Take(10))
    {
        Console.WriteLine($"{prop.Name} = {prop.Value} ({prop.ValueType})");
    }
}

Example 2: Export to JSON

using System.Text.Json;

var config = setupClient.ReadAndParseConfiguration();

var options = new JsonSerializerOptions
{
    WriteIndented = true,
    PropertyNamingPolicy = JsonNamingPolicy.CamelCase,
    Encoder = System.Text.Encodings.Web.JavaScriptEncoder.UnsafeRelaxedJsonEscaping
};

string json = JsonSerializer.Serialize(config, options);
File.WriteAllText("config.json", json);

Example 3: Modify Configuration

var config = setupClient.ReadAndParseConfiguration();

bool success = setupClient.ModifyAndWriteConfiguration(config, (cfg, modifier) =>
{
    // Toggle first 5 booleans
    foreach (var node in cfg.RootNodes.Where(n => n.NodeType == "boolean").Take(5))
    {
        bool newValue = !(bool)node.Value;
        if (modifier.ModifyNode(cfg.GetDataForWriting(), node, newValue))
        {
            Console.WriteLine($"Modified boolean at {node.StartOffset}: {newValue}");
        }
    }
});

if (success)
{
    Console.WriteLine("Configuration successfully updated on server!");
}

Running the Example

cd C:\DEV\COPILOT\geutebruck-api\src\sdk-bridge\ConfigurationExample
dotnet run
# or with custom connection
dotnet run localhost sysadmin masterkey

Technical Details

Binary Format Support

• Type Markers:
  • 0x01 = Boolean (1 byte value)
  • 0x04 = Integer (4-byte little-endian)
  • 0x07 = String (length-prefixed)
  • 0x05 = Marker (special sections like "Rules")

Action Mapping Rules

Rules sections contain action strings in format:

07 01 40 <len_2bytes_LE> <action_data>

Example actions:

• "GSC ViewerConnectLive V <- C"
• "GSC ViewerDisconnect V"
• "Gng SendMail"

Coverage

Parse coverage: 99.996% (281,704 / 281,714 bytes)

Performance

• Parse time: ~200ms for 282KB file
• Node extraction: 19,903 nodes
• Memory: Preserves original 282KB + parsed structure

API Design Decisions

Why In-Place Modification?

The InPlaceConfigModifier preserves the exact binary structure, ensuring:

• ✅ Zero byte difference (critical for stability)
• ✅ Unknown/unparsed bytes preserved
• ✅ Safe round-trip modifications
• ❌ Cannot add/delete nodes (use rebuild approach for that)

Why Not XML/JSON Export from SDK?

Investigation revealed:

• SetupClient API: Only supports binary .set format
• SendQuery API: Only for runtime state, not configuration
• No SDK export: No XML/JSON format available

Therefore, this parser is necessary and the only solution for structured configuration access.
