Properties
boardDetails
readonlyboardDetails:BoardDetails|undefined
Lightweight representation of the board's detail. This information is
provided by the Arduino
CLI
for the currently selected board. It can be undefined if the fqbn is
defined but the platform is not installed.
Deprecated
Use arduinoContext?.currentSketch?.boardDetails instead.
Inherited from
compileSummary
readonlycompileSummary:CompileSummary|undefined
The summary of the latest sketch compilation. When the sketchPath is
available but the sketch has not been verified (compiled), the buildPath
can be undefined.
Deprecated
Use arduinoContext?.currentSketch?.compileSummary instead.
Inherited from
config
readonlyconfig:CliConfig
The currently configured Arduino CLI configuration.
currentSketch
readonlycurrentSketch:SketchFolder|undefined
The currently active sketch (folder) or undefined. The current sketch is
the one that currently has focus or most recently had focus. The current
sketch is in the opened sketches.
dataDirPath
readonlydataDirPath:string|undefined
Filesystem path to the
directories.data
location.
Deprecated
Use arduinoContext?.config?.dataDirPath instead.
Inherited from
fqbn
readonlyfqbn:string|undefined
The Fully Qualified Board Name (FQBN) of the currently selected board in the Arduino IDE.
Deprecated
Use arduinoContext?.currentSketch?.board?.fqbn instead.
Inherited from
onDidChangeConfig
readonlyonDidChangeConfig:Event<ChangeEvent<CliConfig>>
An event that is emitter when the sketchbook
(directories.data) or the data directory
(directories.data) path has changed.
onDidChangeCurrentSketch
readonlyonDidChangeCurrentSketch:Event<SketchFolder|undefined>
An Event that is emitted when the
current sketch has changed. Note that the event also
fires when the active editor changes to undefined.
onDidChangeSketch
readonlyonDidChangeSketch:Event<ChangeEvent<SketchFolder>>
An event that is emitted when the selected board, port, etc., has changed in the sketch folder.
onDidChangeSketchFolders
readonlyonDidChangeSketchFolders:Event<SketchFoldersChangeEvent>
An event that is emitted when sketch folders are added or removed.
openedSketches
readonlyopenedSketches: readonlySketchFolder[]
All opened sketch folders in the window.
port
readonlyport:Port|undefined
The currently selected port in the Arduino IDE.
Deprecated
Use arduinoContext?.currentSketch?.port instead.
Inherited from
sketchPath
readonlysketchPath:string|undefined
Absolute filesystem path of the sketch folder.
Deprecated
Use arduinoContext?.currentSketch?.sketchPath instead.
Inherited from
userDirPath
readonlyuserDirPath:string|undefined
Filesystem path to the
directories.user
location. This is the sketchbook path.
Deprecated
Use arduinoContext?.config?.userDirPath instead.
