# 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:
|
||||
```csharp
|
||||
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):
|
||||
```csharp
|
||||
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:
|
||||
```csharp
|
||||
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($"{prop.Name} = {prop.Value}");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### `ModifyAndWriteConfiguration()`
|
||||
Modify and write back in one operation:
|
||||
```csharp
|
||||
using var client = new GeViSetupClientWrapper("localhost", "sysadmin", "masterkey");
|
||||
|
||||
var config = client.ReadAndParseConfiguration();
|
||||
|
||||
client.ModifyAndWriteConfiguration(config, (cfg, modifier) =>
|
||||
{
|
||||
// Find and modify booleans
|
||||
var booleans = cfg.RootNodes.Where(n => n.NodeType == "boolean").Take(3);
|
||||
foreach (var node in booleans)
|
||||
{
|
||||
bool newValue = !(bool)node.Value;
|
||||
modifier.ModifyNode(cfg.GetDataForWriting(), node, newValue);
|
||||
}
|
||||
|
||||
// Find and modify integers
|
||||
var integers = cfg.RootNodes.Where(n => n.NodeType == "integer").Take(3);
|
||||
foreach (var node in integers)
|
||||
{
|
||||
int newValue = (int)node.Value + 1000;
|
||||
modifier.ModifyNode(cfg.GetDataForWriting(), node, newValue);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
## Complete Example
|
||||
|
||||
See `ConfigurationExample/Program.cs` for a full working example.
|
||||
|
||||
### Example 1: Read and Display
|
||||
```csharp
|
||||
using GeViScopeBridge.SDK;
|
||||
using GeViScopeBridge.Models;
|
||||
|
||||
using var setupClient = new GeViSetupClientWrapper("localhost", "sysadmin", "masterkey");
|
||||
|
||||
if (setupClient.IsConnected)
|
||||
{
|
||||
var config = setupClient.ReadAndParseConfiguration();
|
||||
|
||||
Console.WriteLine($"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
|
||||
```csharp
|
||||
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
|
||||
```csharp
|
||||
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
|
||||
|
||||
```bash
|
||||
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.
