# Snippets

Snippets är ett slags "genvägar" som gör det lättare att skriva kod snabbt. En snippet fungerar genom att man skriver ett par tecken och sedan väljer rätt snippet hur autocomplete-listan.

Några inbyggda snippets:

* cw = System.Console.WriteLine()
* if = en if-sats
* while = en while-loop
* for = en for-loop
* try = ett try-catch-block
* ctor = en konstruktor
* prop = en property

## Lägga till egna snippets

Man kan skapa egna snippets. Man går då till File, Preferences och User Snippets. Där väljer man det språk man vill skapa snippets för. Då öppnas en json-fil där du kan skriva in dina snippets.

```javascript
{
  "Readline": {
      "prefix": "cre",
      "body": "Console.ReadLine()",
      "description": "Inserts a console readline"
  },
  "Writeline":{
    "prefix": "cw",
    "body": "Console.WriteLine(\"$0\");",
    "description": "Inserts a console writeline"
  }
}
```

"Readline" och "Writeline" är namnen på de två snippets som deklareras ovan.

**Prefixen** är de saker man kan skriva för att aktivera dem.

**Bodyn** är det som infogas.

$0 betyder att det är där textmarkören hamnar när man använt snippeten.

Allt du behöver göra sedan är att spara filen.

Man kan läsa mer om att skriva egna snippets [här](https://www.google.com/url?q=https%3A%2F%2Fcode.visualstudio.com%2Fdocs%2Feditor%2Fuserdefinedsnippets\&sa=D\&sntz=1\&usg=AFQjCNHxi86ymlDUghJiBvyTVgMRy2aJsg).

### C\#

{% code title="csharp.json" expandable="true" %}

```json
{
  "Readline": {
    "prefix": "cre",
    "body": "Console.ReadLine();"
  },
  "Writeline": {
    "prefix": "cw",
    "body": "Console.WriteLine($0);",
    "description": "Inserts a console writeline"
  },
  "Clear": {
    "prefix": "cc",
    "body": "Console.Clear();",
    "description": "Inserts a console clear"
  },
  "Random integer": {
    "prefix": "rnd",
    "body": "Random.Shared.Next($0);",
    "description": "Inserts a random next int"
  },
  "Raylib-boilerplate": {
    "prefix": "rayl",
    "body": [
      "using Raylib_cs;\n",
      "Raylib.InitWindow(${1:800}, ${2:600}, \"${3:Title}\");",
      "Raylib.SetTargetFPS(60);\n",
      "while (!Raylib.WindowShouldClose())",
      "{",
      "  $0\n",
      "  Raylib.BeginDrawing();",
      "  Raylib.ClearBackground(Color.White);",
      "  Raylib.EndDrawing();",
      "}"
    ]
  },
  "For-nested": {
    "prefix": "forn",
    "body": [
      "for (int y = 0; y < $1; y++)",
      "{",
      "  for (int x = 0; x < $2; x++)",
      "  {",
      "    $0",
      "  }",
      "}"
    ]
  }
}
```

{% endcode %}

### XML (för csproj)

De här gör det enkelt att använda [resursfiler](/filhantering/resursfiler.md).

{% code title="xml.json" expandable="true" %}

```json
{
  "Include content": {
    "prefix": "include",
    "body": "<Content Include=\"$0\" CopyToOutputDirectory=\"Always\"/>",
  },
  "Item group": {
    "prefix": "ig",
    "body": [
      "<ItemGroup>",
      "  $0",
      "</ItemGroup>"
    ]
  }
}
```

{% endcode %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://csharp.progdocs.se/mjukvara/visual-studio-code/snippets.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
