Extension Settings

This extension contributes the following settings:

• presentation-buddy.delay: Delay (in ms) between keys entered. Defaults to 100ms.

Instructions

Note: Any instruction will accept a "skip": true settings causing it to be ignored

TypeText

Type some text at the current cursor position of the currently open file. The text setting can either be a string or an array of strings. In the case of an array of strings each string is entered on a new line.

Example:

{
  "type": "typeText",
  "text": [
    "// Some comment",
    "const lineTwo = true;"
  ]
}

TypeTextFromFile

Type some text at the current cursor position of the currently open file. The text is read from the file indicated by the path. The path is relative to the .presentation-buddy folder.

Example:

{
  "type": "typeTextFromFile",
  "path": "./text-source.js"
}

OpenFile

Opens the file specified in the editor. Note that the file needs to exist.

See also: CreateFile

Example:

{
  "type": "openFile",
  "path": "src/my-file.js"
}

GoTo

Go to a specific position in the currently open file. The positions are 1 based so they match up with what Visual Studio Code displays. Both the line and column default to 1 if not specified.

Example:

{
  "type": "goto",
  "line": 75,
  "column": 21
}

Select

Select from the current position to a specific position in the currently open file. The positions are 1 based so they match up with what Visual Studio Code displays. Both the line and column default to 1 if not specified.

Example:

{
  "type": "select",
  "line": 75,
  "column": 21
}

Command

Executes one of the standard Visual Studio Code commands. The command should be one of the standard Visual Studio Code command names. See the Keyboard shortcuts for the known commands. When the command requires additional parameters an args array or primitive types can be passed along. Add an optional repeat settings if a command needs to be execured multiple times.

Note: Not all commands might work as expected so your mileage may vary.

Examples:

{
  "type": "command",
  "command": "workbench.action.files.save"
},
{
  "type": "command",
  "command": "editor.action.smartSelect.expand",
  "repeat": 2
},
{
  "type": "command",
  "command": "editor.action.clipboardPasteAction"
}

CreateFile

Creates the file specified and opens it in the editor.

Note: If the file specified already exists it is replaced with an empty file.

Example:

{
  "type": "createFile",
  "path": "src/my-file.js"
}

Wait

Pauses playback for a pecified period. A delay can be passed as either a number representing the number of milliseconds to wait or and the "manual". In the case of "manual" playback will only resume when the Presentation Buddy: Continue command is executed. If the save option is set to true all dirty editor files in the workbench will be saved first.

Examples:

{
  "type": "wait",
  "delay": 10000
},
{
  "type": "wait",
  "delay": "manual",
  "save": true
}
