espurna compiles in Arduino IDE, but doesn't in Visual Micro

Hello. I have an issue compiling espurna project (https://github.com/xoseperez/espurna) with Visual Micro 1808.25 on generic esp8285, the compilation stops with:
Code
Select All
espurna.ino: 66:37: error: 'T' has not been declared
espurna.ino: 67:37: error: 'T' has not been declared
[... several messages like this follow ...]
 


The project consists of multiple .ino files which Visual Micro joins together into one file relying on generated function prototypes. I tracked down the issue to not supplying the right function prototypes with templates as in (settings.ino):
Code
Select All
template<typename T> bool setSetting(const String& key, T value); 


but instead in espurna.cpp generated by extension the code reads:
Code
Select All
bool setSetting(const String& key, T value); 


thereby causing many similar errors. Can you look into this issue and provide any solution?

Hi,

Yes prototypes are a discussion at the moment and will be implemented soon.

I don't know why vm is assuming bool. It uses simple regex so there must be a bool version in the code somehere

Normally you can just add the prototypes yourself somewhere before they are defined and before the code that uses them.

template<typename T> bool setSetting(const String& key, T value); 

Does this help?

As I can see the project includes also all prototypes in one file called 'config/prototypes.h', so generating prototypes shouldn't be necessary for this project. But with the new version of the extension I can't see project properties anymore, which would help me disable prototype generating procedure in vm. Do you know how can I force VM to stop generating prototypes for me?

I see. I will look into the properties issue later today

There is a new build in the gallery which I hope resolves the missing property tool window.

Thanks for the report.

Hello, I am still experiencing this issue of not providing correct prototypes of functions, for example .cpp file generated from multiple .ino files reads:
bool setSetting(const String& key, T value); 
instead of:
template<typename T> bool setSetting(const String& key, T value); 

Arduino IDE compiles just fine, because it follows templates correctly. I believe the problem is that regex matching function prototypes into main.cpp file omits "template<typename T>" part completely.

Will templates in prototypes generation be supported anywhere close in the future? I really like Visual Micro, it's miles above Platformio Smiley

put templates in .h or .cpp files
