Hi,
I have problems using PGF graph drawing with ConTeXt. The problem is
described on https://tex.stackexchange.com/questions/414102/
It all boils down to Lua trying to load wrong file. When
require 'pgf.gd.control'
is called, ConTeXt resolvers come into play and 'lua variable format'
locates Control.lua -- note the uppercase letter here -- which cannot be
loaded (on Linux) and 'require' fails:
> sandbox > requiring: pgf.gd.control
> resolvers > libraries > locating, level '1', method 'already loaded',
> name 'pgf.gd.control'
> resolvers > libraries > locating, level '1', method 'preload table',
> name 'pgf.gd.control'
> resolvers > libraries > locating, level '1', method 'lua variable
> format', name 'pgf.gd.control'
> resolvers > libraries > lua format, checking 33 paths
> resolvers > libraries > lua format, identifying 'pgf/gd/control.lua'
> using format 'tex'
> resolvers > libraries > lua format, 'pgf/gd/control.lua' found on

I suspect some part of the system (ConTeXt? kpsewhich? TeXLive?) messes
up and the resolver instead of pgf/gd/control.lua hits
pgf/gd/force/Control.lua. But I have plainly no experience in where to
look...
One more place, where I found some traces: in
texmf-var/luatex-cache/context/a86c089b384a3076dc514ba966a1fac9/trees/929f6dbc83f6d3b65
dab91f1efa4aacb.lua file I have (in ["content"]["files"])
> ["control.lua"]={ "tex/generic/pgf/graphdrawing/lua/pgf/gd",
> "tex/generic/pgf/graphdrawing/lua/pgf/gd/force" }
as well as (in ["content"]["remap"])
> ["control.lua"]="Control.lua"
Clearly not OK.
My system is current TeXLive 2017. LuaTeX 1.0.4. ConTeXt 1.01. Ubuntu
14.04 and 16.04.
