# PyInstaller spec for DataTools.
#
# Build (from the repo root, after ``pip install pyinstaller``):
#
#     pyinstaller build/datatools.spec
#
# Output: ``dist/DataTools/`` (folder mode) and ``dist/DataTools.exe``
# (or platform equivalent) on Windows; ``dist/DataTools.app`` on macOS
# when packaged via ``--target-arch universal2``. See ``build/README.md``
# for the full per-platform recipe.
#
# Why folder-mode (one-dir) is the default:
#   * Streamlit's static assets + Python interpreter + ~300 MB of deps
#     compress poorly into onefile. Onefile mode unpacks every launch
#     to a temp dir — adds 5-15 s startup latency that confuses
#     non-technical buyers ("did it crash?").
#   * Folder mode lets the installer (Inno Setup on Win, .dmg on Mac)
#     run a one-time copy. Subsequent launches are instant.
#
# Cross-platform note: this single spec file is built ON each target
# platform. Cross-compilation isn't supported — Mac builds need a
# Mac, Windows builds need a Windows machine (or a Windows GitHub
# Actions runner). See build/README.md for the matrix recipe.

# ----- Hidden imports ------------------------------------------------
# PyInstaller's static analyser misses everything Streamlit reaches
# through ``importlib`` and the per-tool registries our app uses. We
# exhaustively pull every submodule of the libraries that bridge
# user code to runtime — better a 50 MB-bigger bundle than a runtime
# ImportError on the buyer's machine.
