在我的 VS Code 擴展中，我注冊了一個洗掉診斷的命令：
extension.ts
context.subscriptions.push(
vscode.commands.registerCommand(
DELETE_DIAGNOSTIC_COMMAND,
() => removeDiagnostic()
)
);
這是removeDiagnostic函式的樣子：
utils.ts
export function removeDiagnostic(): void {
const editor = window.activeTextEditor;
if(editor){
const diagnosticStart = editor.selection.start;
const diagnosticEnd = editor.selection.end;
const diagnosticRange = new Range(diagnosticStart, diagnosticEnd);
editor.edit(editBuilder => {
editBuilder.replace(diagnosticRange, "");
});
}
在DELETE_DIAGNOSTIC_COMMAND這里提供的代碼操作：
MyCodeActionProvider.ts
const DELETE_DIAGNOSTIC_COMMAND = 'delete-diagnostic.command';
export class MyCodeActionProvider implements vscode.CodeActionProvider {
public static readonly providedCodeActionKinds = [
vscode.CodeActionKind.QuickFix
];
provideCodeActions(document: vscode.TextDocument, range: vscode.Range | vscode.Selection, context: vscode.CodeActionContext, token: vscode.CancellationToken): vscode.CodeAction[] {
return context.diagnostics
.filter(diagnostic => diagnostic.code === 'myDiagnosticCode')
.map(diagnostic => this.createCommandCodeAction(diagnostic));
}
private createCommandCodeAction(diagnostic: vscode.Diagnostic): vscode.CodeAction {
const action = new vscode.CodeAction('Remove deprecated intrinsic', vscode.CodeActionKind.QuickFix);
action.command = { command: DELETE_DIAGNOSTIC_COMMAND, title: 'Remove deprecated intrinsic', tooltip: 'This will remove the deprecated intrinsic from the editor.' };
action.diagnostics = [diagnostic];
action.isPreferred = true;
return action;
}
}
并且，代碼操作提供程式在此處注冊：
extension.ts
context.subscriptions.push(
vscode.languages.registerCodeActionsProvider('myFileExtension', new MyCodeActionProvider(), {
providedCodeActionKinds: MyCodeActionProvider.providedCodeActionKinds
})
);
在removeDiagnostic函式中，當我將滑鼠懸停在診斷上時，我想獲取診斷的范圍，以便運行快速修復命令將其洗掉。
更清楚地說，當我從Problems選項卡運行命令時，我可以洗掉選定的范圍，但當我將滑鼠懸停在診斷上時不能：
當我將滑鼠懸停在它上面運行命令時，如何從編輯器中洗掉診斷？
uj5u.com熱心網友回復：
將代碼操作中的診斷傳遞給屬性中的DELETE_DIAGNOSTIC_COMMAND命令，args并在命令中使用range診斷的屬性
