1c Devtools Cursor

1C Dev Tools for Cursor

Skill by ara.so — Devtools Skills collection.

Extension for Cursor IDE that provides comprehensive development tools for the 1C:Enterprise 8 ecosystem. Offers command palette integration, task tree navigation, configuration management, extension handling, and BSL debugging capabilities.

What It Does

1C Dev Tools integrates 1C:Enterprise development workflow into Cursor IDE:

• Information Base Management: Create, update, export/import databases
• Configuration Operations: Load/unload configurations from sources (src/cf), build .cf files
• Extension Management: Work with multiple extensions (src/cfe), compile .cfe files
• External Files: Build and disassemble external reports/processors
• Dependency Management: Initialize and manage packagedef dependencies
• Launch Tools: Start Enterprise or Configurator from IDE
• BSL Debugging: Attach debugger with variable inspection, watch expressions, and call stack navigation

All commands accessible through:

• 1C Dev Tools panel
• Command palette (Ctrl+Shift+P)
• Task tree in bottom panel

• Remote: Attempts connection
• Protocol: HTTP only (configure in Configurator)

Fine-tune debug timings via settings (1c-dev-tools.debug.timings):

{
    "1c-dev-tools.debug.timings": {
        "varFetchDelayMs": 50,
        "calcWaitingTimeMs": 100,
        "pingIntervalMs": 50,

        "immediatePingDelaysMs": [25, 50, 100],
        "evalExprRetryDelaysMs": [50, 100],
        "variablesRequestRetryDelaysMs": [50, 100, 150],
        "pingDbgtgtIntervalMs": 5000
    }
}

Debugging BSL Modules

Starting Debug Session

1. Set breakpoints in .bsl files (click left margin)
2. Press F5 or Run → Start Debugging
3. Select configuration: "1C: Launch with background jobs" or "1C: Attach"
4. Extension connects to dbgs.exe on specified port
5. Launch 1C:Enterprise (manually or via command)

Variable Inspection

Watch panel (add expressions):

• Right-click variable in editor → "Show value in separate window"
• Click "Calculate value" button in Watch panel header
• Enter expression: Query.TemporaryTablesManager.Tables[0]

Supported types:

• Структура (Structure): Expands with fields and values
• Соответствие (Map): Expands with Key/Value pairs
• ТаблицаЗначений (ValueTable): Shows columns, indexes, rows [0], [1], etc.
• МенеджерВременныхТаблиц (TempTablesManager): Shows temporary tables tree

Calculate Expression

Right-click in editor → "Calculate value":

// In stopped context, evaluate:
Query.TemporaryTablesManager.Tables[0].GetColumns()
Result.Find("MyValue", "FieldName")
Collection.Count() > 10

Result displays in table: Property | Value | Type

Call Stack Navigation

Note: Local variables don't display in default view. To inspect:

1. Select stack frame (procedure/function) in Call Stack panel
2. Add variable to Watch panel
3. Variable evaluates in selected frame context

Step Commands

F10 - Step Over
F11 - Step Into
Shift+F11 - Step Out
F5 - Continue
Shift+F5 - Stop

Extension auto-refreshes stack and variables with optimized ping intervals.

Common Patterns

Initial Project Setup

# 1. Create project structure
mkdir my-1c-project
cd my-1c-project
mkdir -p src/cf src/cfe build/ib build/commit

# 2. Initialize packagedef
# Open in Cursor, press Ctrl+Shift+P → "1C: Initialize packagedef"

# 3. Create env.json (see Configuration section)

# 4. Create empty infobase
# Ctrl+Shift+P → "1C: Create empty infobase"

Load Configuration from External Source

# 1. Place 1Cv8.cf in project root
# 2. Ctrl+Shift+P → "1C: Load from 1Cv8.cf"
# 3. Export to sources: "1C: Export to src/cf"

Incremental Development Workflow

1. Work in Configurator, make changes
2. Export changes: 1C: Export update to src/cf
3. Commit to version control
4. Teammates update: 1C: Update from src/cf (reads build/commit/Commit.txt)

build/commit/Commit.txt format (one file per line):

src/cf/Documents/Документ1/Ext/ManagerModule.bsl
src/cf/Catalogs/Справочник1.xml
src/cfe/Extension1/Documents/Документ1/Ext/ObjectModule.bsl

Working with Multiple Extensions

# Extensions stored in subdirectories:
src/cfe/
├── Extension1/
│   ├── Configuration.xml
│   └── Documents/...
└── Extension2/
    ├── Configuration.xml
    └── Catalogs/...

# Commands operate on all extensions:
1C: Load from src/cfe          # Loads Extension1 + Extension2
1C: Export update to src/cfe   # Exports changes from all

Build External Processor

// src/ExternalReports/MyReport/ObjectModule.bsl
Процедура ПриКомпоновкеРезультата(ДокументРезультат, ДанныеРасшифровки, СтандартнаяОбработка)
    // Report logic
КонецПроцедуры

1. Place sources in src/ExternalReports/MyReport/
2. Ctrl+Shift+P → 1C: Build external report/processor
3. Select MyReport
4. Output: MyReport.erf in project root

Debug BSL Code Example

// CommonModule.bsl
Функция ВыполнитьЗапрос(ТекстЗапроса)
    Запрос = Новый Запрос;
    Запрос.Текст = ТекстЗапроса;
    
    // Set breakpoint here ⬅
    Результат = Запрос.Выполнить();
    
    ТЗ = Результат.Выгрузить();
    Возврат ТЗ;
КонецФункции

When stopped at breakpoint:

1. Add Запрос to Watch
2. Expand Запрос.МенеджерВременныхТаблиц.Таблицы
3. Right-click ТЗ → "Show value in separate window" (after step-over)

Troubleshooting

Extension Not Activating

Symptom: 1C Dev Tools panel not visible
Solution:

• Ensure packagedef exists in project root
• Restart Cursor
• Check Output panel → "1C Dev Tools" for errors

oscript Command Not Found

Symptom: Commands fail with "oscript not recognized"
Solution:

• Install OneScript: https://oscript.io/
• Create Windows environment variable: oscript = C:\Program Files\OneScript\bin\oscript.exe
• Restart Cursor after setting variable

Debug Server Connection Failed

Symptom: Cannot connect to debug server
Solution:

• Verify dbgs.exe running (Task Manager)
• Check launch.json → debugServerHost matches actual hostname
• Ensure port 1560 (or configured) not blocked by firewall
• In Configurator: Debug → Change protocol to HTTP
• Restart debug server manually: dbgs.exe --addr localhost --port 1560

Variables Not Showing in Watch

Symptom: Watch panel empty or shows "unavailable"
Solution:

• Select correct Call Stack frame (click procedure name)
• Manually add variable name to Watch (don't rely on auto-detection)
• Increase varFetchDelayMs in settings if timing issue
• Use "Calculate value" button instead for complex expressions

Load from src/cf Fails

Symptom: "Configuration load error"
Solution:

• Verify src/cf/Configuration.xml exists
• Check env.json → --ibconnection path correct
• Ensure infobase not locked (close Configurator/Enterprise)
• Try "1C: Create empty infobase" first

Update from src/cfe Skips Files

Symptom: Changes not applied
Solution:

• Check build/commit/Commit.txt contains modified file paths
• Use full export first: 1C: Export to src/cfe
• Verify extension names match subdirectory names exactly
• Manually add missing paths to Commit.txt (relative to project root)

Build External Processor No Output

Symptom: Build completes but no .erf/.epf file
Solution:

• Check source structure includes ObjectModule.bsl or ManagerModule.bsl
• Verify XML metadata files present
• Look in project root and build/ directory
• Check Output panel for oscript errors

Incremental Update Applies Wrong Files

Symptom: Unrelated modules changed after update
Solution:

• Commit.txt format must be: one file path per line, relative to project root
• Use forward slashes: src/cf/Documents/Doc1.xml not src\cf\Documents\Doc1.xml
• No empty lines or comments in Commit.txt
• Regenerate with 1C: Export update to src/cf after known state

TypeScript API (for Extension Development)

If extending this project:

import * as vscode from 'vscode';

// Access extension context
const ext = vscode.extensions.getExtension('asweetand-a11y.devtool1c');
if (ext) {
    const api = await ext.activate();
}

// Register custom command
vscode.commands.registerCommand('1c-dev-tools.customCommand', () => {
    // Execute oscript
    const terminal = vscode.window.createTerminal('1C Tools');
    terminal.sendText('oscript build.os');
});

// Read env.json configuration
const workspaceRoot = vscode.workspace.workspaceFolders?.[0].uri.fsPath;
const envPath = path.join(workspaceRoot, 'env.json');
const envConfig = JSON.parse(fs.readFileSync(envPath, 'utf8'));
const ibConnection = envConfig.default['--ibconnection'];
