C/C++: Improved macros and expressions

[RunDevelopment]

This can be seen as an extension of #2320.

Macro expressions after the directive are now highlighted. I also added some highlighting for macro-specific syntaxes like \ at line ends and the concatenation operator.

when will it be possible to download the prismjs that includes this #2440 enhancement?

[RunDevelopment]

@blotfi Right now!

[blotfi]

just to be more precise, it must be valid in C language (and therefore in C++ language) #2440 enhancement
thanks

[blotfi]

@blotfi Right now!

you mean if i download
https://prismjs.com/download.html#themes=prism&languages=clike+c+cpp+json&plugins=line-numbers+file-highlight+keep-markup

I will find the modification (for C and CPP) ?

Yes.

it must be valid in C language

Macro expressions will be highlighted as C code in C and as C++ code in C++. You can see this with #define macros that contain C++ keywords.

C:

C++:

Is that what you meant?

I am testing now, 2 min
I see you put:

		'directive-hash': /^#/,
		'punctuation': /##|\\(?=[\r\n])/,
		'expression': {
			pattern: /\S[\s\S]*/,
			inside: Prism.languages.c

Works great
Thanks

I will open another issue for #include <xc.h>
it works well with file
<pre data-src="code/TP0/cmde.c"></pre>
but not if it is included in the html

<pre data-start="0" ><code class="language-cpp line-numbers">
#include <xc.h>
return;
#ifdef NON
void list()
{
}
