I probably should also show my ./configure line, because this bug seems
to be caused by --force-config:
./configure --prefix=${HOME}/.self/programs/luarocks-2.0.13
--lua-version=5.2 --lua-suffix=5.2
--with-lua-include=/usr/include/lua5.2 --versioned-rocks-dir --force-config
(Ubuntu version)
`home_config_file` in cfg.lua, which later becomes `home_file` in
help.lua, only gets set if `site_config.LUAROCKS_FORCE_CONFIG` is false.
Changing help.lua:82 from
User configuration file: ]]..home_file .. " (" ..
get_status(home_ok) ..")\n")
to
User configuration file: ]]..tostring(home_file) .. " (" ..
get_status(home_ok) ..")\n")
fixes the problem (so far). But there will be a similar problem in
cfg.lua:267 on Windows:
home_config_file = home_config_file:gsub("\\","/")
-->
home_config_file = home_config_file and home_config_file:gsub("\\","/")
