browser_side: added input history in the unibox: This functionality uses a file from the sat project: use the -I parameter of pyjsbuild to add sat library to your PYJSPATH. To ease also possible to use your sat source directory instead of the library, you just need to trick pyjsbuild with a symbolic link: SAT=~/workspace/sat if [[ ! -e $SAT/sat ]]; then ln -sf $SAT/src $SAT/sat; fi This will allow you to import like that in libervia.py: from sat.tools.frontend.misc import InputHistory And then you can build with: $PYJS/bin/pyjsbuild libervia --no-compile-inplace -m -I $SAT
