Feature request: compile current file in the editor

Development Tools IDE 2.x
1

Dear Arduino Team,

Could you please consider adding feature 'compile current file in the editor' and allow its mapping to a shortcut ?
In other IDEs I've got it mapped to 'Alt + x' - I see it is still available in Arduino IDE.

Keil uVision

When I edit a cpp file, I often want to check if my edits are compilable and not neccessarily interested in linking.

Thank you
Frank

Sorry, I can't see the intended target.
IMHO even possible linking errors are relevant especially when changing things on a class, so why don't you just use "Verify" function to test it? I do that every time I just need to check everything I'm writing is formally OK...

"Sorry, I can't see the intended target."

Target is to compile .cpp file currently active in the editor. I do not know IDE without that functionality (uVision, MSVC, QtCreator). It is cruitial feature.

I do and it takes ~15seconds for IDE verifying libraries before it tries to compile my file I am interested in at that moment. When I want to link that is another matter and will deal with that later. So there will be, hopefully, 'Verify Link'(15seconds) and 'Verify file'(150milliseconds).

Yes, but why? Just for a formal syntax testing? I have never had that need, because if I create or change a class I need to check also the other modules using such class.
Anyway, one more functionality doesn't have any kinda drawback and could be useful for someone (even if I don't think I'll never use it, I'm not against the idea...;-)).

"Just for a formal syntax testing?"
Yes.

"I have never had that need"
This is very interesting. In my case it is amongst the most used feature for many years.

"if I create or change a class I need to check also the other modules"
E.g. when you edit class implementation in cpp you might not/dont need to check.

Example:

static constexpr int32_t  SCVbattMax_mV { 10'000 };

I did not know IDE compiler does not accept ' to mark 000. 15s wait.

Next

static constexpr int32_t  SCVbattScaling { INT32_C ( 47 ) };
static_assert ( 212 == SCVbattMax_mV / SCVbattScaling, "" );

I would like to check the assertion. 15s wait.

6

This is clear, if there are just "internal" changes while keeping the interface unchanged. So I can understand your point of view, even if I have never needed such a "single line" control or on a specific statement (unless I am not very familiar with that specific language, see the "single quote" you used for thousands...), I make a "batch" of changes and test their syntax by compiling the project.

Anyway, to be clear I'm not saying I'm against your proposal... :wink:

"Sorry, I can't see the intended target."

F.e. I work on a structure and all I need is to check the syntax. So to achieve that, I now wait 10seconds just to see that I forgot a semicolon. IDE does its usual 'check all' procedure. I am not interested in libs dependencies, candidates etc. There is no change in libraries. I do not want to build other modules of my app. I work on one module, nothing else - little structure so there is no need to link.

There is already IDE Beta version with 'Upload w/o build' so hopefuly 'Compile current file only' will follow soon.
