thanks jose95. Alan, heres that quick workaround for iOS builds breaking on that fp system.PathForFile returning nil. Means your console print is not overiden but at least it doesnt break builds. Sorry its only a workaround.
for those of you just picking up on this print override. just name this a .lua file and require it in your main before your print statements start for it to work
[lua]
– -- debug print overide
– -- you can use _print() in code if you want original
_print = print
local localdir
local projectCodeRootString
function string.join( … )
– function requires a string, a separator, and at least one argument;
– if this condition is not met, print and error and return nil
if ( #arg < 3 ) then
_print( “Error: required string and separator missing” )
return nil
end
– the string is the first argument
local str = arg[1]
– the separator is the second argument
local separator = arg[2]
– loop from the third index (the first real argument to join to the string)
for i = 3, #arg do
– if the argument is a string, append it along with the separator
if ( type(arg[i]) == “string” ) then
if ( str:len() ~= 0 ) then
str = str … separator
end
str = str … arg[i]
– if the argument is a table, loop through it just like above
elseif ( type(arg[i]) == “table” ) then
local t = arg[i]
for j = 1, #t do
if ( type( t[j] ) == “string” ) then
if ( str:len() ~= 0 ) then
str = str … separator
end
str = str … t[j]
end
end
end
end
return str
end
function initialise_print( … )
print = function(…)
if arg == nil then
return
end
local function cleanText(text)
if text == nil then
return “nil”
end
return text
end
– local fp = system.pathForFile( “main.lua”, system.ResourceDirectory )
– local localdir = fp:gsub( “main.lua”, “” )
– local projectCodeRootString = localdir
– local projectCodeRootString = ‘/LeapFrog/code/’
local source_file = cleanText(debug.getinfo(2).source)
local path_start, path_end = source_file:find(projectCodeRootString)
if path_start == nil then
return
end
local debug_path = cleanText(source_file:sub(path_end, source_file:len()))
– This gets the line number:
local line = cleanText(debug.getinfo(2).currentline)
– This gets the function name:
local funcName = cleanText(debug.getinfo(2, “n”).name)
local str = string.join("", " ", arg)
_print(“°”…debug_path…":"…funcName…"()"…":"…line…": "…str) – using the ° degree symbol as easy file_regex target
– _print(debug_path…":"…funcName…"()"…":"…line…": "…str)
end
end
– this is done so that the ios build doesnt break
local fp = system.pathForFile( “main.lua”, system.ResourceDirectory )
if fp ~= nil then
localdir = fp:gsub( “main.lua”, “” )
projectCodeRootString = localdir
_print("Project Location: "…“°°”…localdir…“°°”) – this is to create a nice easy tag
initialise_print()
else
print = _print – cancel overriding
print( “ios error: fp: is nil. customm print overide cancelled” )
end
[/lua]
