annotate browser_side/radiocol.py @ 239:b911f2b43fd4
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
