From a3ef752f1f1d8939fdbd64fc5dd8e5cdd5cab450 Mon Sep 17 00:00:00 2001 From: cncsmonster Date: Sun, 31 May 2026 01:51:51 +0800 Subject: [PATCH 01/23] fix(clipboard): use platform-native tools for image paste on Linux Replace @teddyzhu/clipboard native module with wl-paste/xclip on Linux to fix image paste in WSL2+Wayland environments. The native module uses X11 protocol and cannot read clipboard images when the session uses Wayland (common in WSL2 with WSLg). This causes clipboardHasImage() to return false even when the clipboard contains an image. Changes: - Use wl-paste --list-types to detect images (Wayland) - Use xclip -selection clipboard -t TARGETS -o to detect images (X11) - Handle image/bmp format from Windows clipboard (WSL2 exposes BMP) - Convert BMP to PNG using Python PIL when available - Detect clipboard tool via WAYLAND_DISPLAY when XDG_SESSION_TYPE is unset - Keep @teddyzhu/clipboard as fallback for macOS/Windows Fixes QwenLM/qwen-code#3517 Fixes QwenLM/qwen-code#2885 --- packages/cli/src/ui/utils/clipboardUtils.ts | 353 +++++++++++++++++--- 1 file changed, 315 insertions(+), 38 deletions(-) diff --git a/packages/cli/src/ui/utils/clipboardUtils.ts b/packages/cli/src/ui/utils/clipboardUtils.ts index a28c2a49c5f..267307db6ee 100644 --- a/packages/cli/src/ui/utils/clipboardUtils.ts +++ b/packages/cli/src/ui/utils/clipboardUtils.ts @@ -5,41 +5,186 @@ */ import * as fs from 'node:fs/promises'; +import { createWriteStream } from 'node:fs'; +import { execSync, spawn } from 'node:child_process'; import * as path from 'node:path'; import { createDebugLogger } from '@qwen-code/qwen-code-core'; const debugLogger = createDebugLogger('CLIPBOARD_UTILS'); -// eslint-disable-next-line @typescript-eslint/no-explicit-any -type ClipboardModule = any; +// Track which tool works on Linux to avoid redundant checks/failures +let linuxClipboardTool: 'wl-paste' | 'xclip' | null | undefined; -let cachedClipboardModule: ClipboardModule | null = null; -let clipboardLoadAttempted = false; +/** + * Detect the Linux clipboard tool. + * Handles WSL2 where XDG_SESSION_TYPE may be unset but WAYLAND_DISPLAY is set. + */ +function getLinuxClipboardTool(): 'wl-paste' | 'xclip' | null { + if (linuxClipboardTool !== undefined) return linuxClipboardTool; + + const sessionType = process.env['XDG_SESSION_TYPE']; + const waylandDisplay = process.env['WAYLAND_DISPLAY']; + const display = process.env['DISPLAY']; -async function getClipboardModule(): Promise { - if (clipboardLoadAttempted) return cachedClipboardModule; - clipboardLoadAttempted = true; + let toolName: 'wl-paste' | 'xclip' | null = null; + + if (sessionType === 'wayland' || waylandDisplay) { + toolName = 'wl-paste'; + } else if (sessionType === 'x11' || display) { + toolName = 'xclip'; + } else { + linuxClipboardTool = null; + return null; + } try { - const modName = '@teddyzhu/clipboard'; - cachedClipboardModule = await import(modName); - return cachedClipboardModule; - } catch (_e) { - debugLogger.error( - 'Failed to load @teddyzhu/clipboard native module.
