How to change policy tooltips?

[Thalassicus]

I'd like to add lines showing policy_flavor values for each policy tooltip, for debugging purposes. I found where it gets the Help text for policies in SocialPolicyPopup.lua and made a change.

Spoiler :

This produced an error, "attempt to concatenate global 'strToolTip' (a nil value)":

-- Tooltip
local strTooltip = Locale.ConvertTextKey( policyInfo.Help ) or " ";

-- AI Flavor Debug
strToolTip = strToolTip .. "[NEWLINE][NEWLINE]----------------[NEWLINE]AI Priorites (debug info):"
for flavorInfo in GameInfo.Policy_Flavors(string.format("PolicyType = '%s'", policyInfo.Type)) do
	strToolTip = strToolTip .. string.format("[NEWLINE]%s %s", flavorInfo.Flavor, Locale.ToLower(string.gsub(flavorInfo.FlavorType, "FLAVOR_", "")));
end

This did not error, but does not show the "----------------" line at all:

-- Tooltip
local strTooltip = Locale.ConvertTextKey( policyInfo.Help );

-- AI Flavor Debug
strToolTip = (strToolTip or " ") .. "[NEWLINE][NEWLINE]----------------[NEWLINE]AI Priorites (debug info):"
for flavorInfo in GameInfo.Policy_Flavors(string.format("PolicyType = '%s'", policyInfo.Type)) do
	strToolTip = strToolTip .. string.format("[NEWLINE]%s %s", flavorInfo.Flavor, Locale.ToLower(string.gsub(flavorInfo.FlavorType, "FLAVOR_", "")));
end

I'm really confused. It's almost like the "AI Flavor Debug" block of code I added is not in the scope of the rest of the code, so it does not see the local strToolTip, and searches for a global instead. It doesn't make any sense, but is the only explanation I can think of. I've been programming six hours and getting rather tired so I suspect I'm overlooking something really obvious.

strTooltip vs strToolTip (read the error msg )

As I thought!

I see how this happened... Firaxis used this for policy trees:

local strToolTip = Locale.ConvertTextKey(policyBranchInfo.Help);

for policies:

local strTooltip = Locale.ConvertTextKey( policyInfo.Help );

In the same function!

Seriously, they need more code standardization in their work... thanks for the help!
