Would D plan to support that in syntax level?


it depends if some dip like

thanks arturg !
hope this can be done sooner

how to understand different attribute styles?

[timepp via Digitalmars-d-learn]

there is "@disable", using @ as prefix;
there is "__gshared", using __ as prefix;
there is also "align", not using prefix.

I failed to summarize a rule here. Can anyone tell the underlined 
philosiphy?

Are you sure?

any usage example?

consider a normal usage:
writeln("done.");

I just want a runtime output. how can I tell the compiler not to 
print "done." at compile time?

DUB: can I fully control the output file name?

[timepp via Digitalmars-d-learn]

I'm writing a Total Commander plugin, which has the "wdx" file 
extension, so I wish to let dub generate xxx.wdx directly but not 
xxx.dll.


How can I write my file to achieve this goal?

my dub.json:


{
"name": "tckeyex",
"targetType": "dynamicLibrary",
"description": "A minimal D application.",
"copyright": "Copyright 2016, idtong",
"authors": ["idtong"],
"sourceFiles": ["source/app.def"],
"dependencies": {
"wind": { "path": "thirdparty/wind" }
}
}


and my build script:

@echo off

call makeversion.bat

dub build -b release
copy /y tckeyex.dll tckeyex.wdx

dub build -b release -a x86_64
copy /y tckeyex.dll tckeyex.wdx64
