annotate libervia/server/pages.py @ 1246:aaf28d45ae67
pages: browser code, first draft:
- code for browser can now be specified if a page subdirectory named `_browser` exists
- the default engine used is `Brython` (not yet implemented, so it will do nothing for
now)
- build_path now uses C.SITE_NAME_DEFAULT for default site instead of empty string, to
avoid collision with other sites
- ProtectedFile transtype path (first positional argument) to str, so a pathlib.Path can
be used
