From 892070f3dec1dc690983fd862880e37e711c2516 Mon Sep 17 00:00:00 2001 From: SulfurNitride Date: Sun, 12 Apr 2026 17:55:56 -0500 Subject: Add BSA in-memory extraction and nested preview support bsatk: - Archive::extractToMemory() extracts a file directly into a byte buffer instead of a filesystem path, backed by a std::ostringstream sink. - Archive::findFile() locates a file by relative path, case-insensitive and separator-agnostic, walking the folder tree recursively. - extractDirect/extractCompressed now take std::ostream& so both the ofstream and ostringstream paths share the same implementation. libbsarch: shim rewrite on Linux to map the Windows API surface onto bsatk::Archive, enabling preview_bsa to open vanilla BSAs via the same interface as other plugins. preview_bsa: double-click on a file in the BSA tree now extracts the bytes via extractToMemory() and hands them to IOrganizer::previewFileData for nested preview rendering (e.g. NIF inside a BSA). uibase + organizerproxy + organizercore: new IOrganizer::previewFileData virtual that routes in-memory file bytes through the first registered IPluginPreview matching the extension. Uses heap + WA_DeleteOnClose + open() to avoid nested exec() softlock from mod info filetree -> preview_bsa tree -> nif preview. docker/build-inner.sh: stage preview_nif shaders into plugin_data/shaders so ShaderManager can load them via IOrganizer::getPluginDataPath().
