CTFE execute will be very useful on web develop, for example It is very hard to create a CTFE version template engine with rich feature. But we can use execute call to transe template file to d code string, then mixed it to application. The vibed project is very cool and I want to add my Jade template to this, but I can't find other way to do it. Maybe we also need a compiler option to enable this CTFE io operate because security.

Let me make myself more clear, what I suggestion is something like this: mixin( std.process.execute("/usr/bin/template_engine template_file_path.htm") );

You can do a lot with import(filename);Maybe we also need a compiler option to enable this CTFE io operate because security.

When translate the template code to D code, need a lot D type arguments information. And one Web application may need very many page, and the type may change frequently. If I am not doing it on the CTFE will geometric increase workload. If D want to be participants in the web field, I think that this feature sooner or later will be needed.
By coincidence, Walter recently mentioned something similar being integrated into D to support DStep: http://forum.dlang.org/post/jta97l$10hm$1 digitalmars.com So perhaps the above mixin would be: import "template_file_path.htm"; According to the link, that would execute: htm_to_D template_file_path.htm The htm_to_D program would generate a .d module which would then get imported.

--f46d0435c1d20cb63f04c12a0408 Content-Type: text/plain; charset=UTF-8 Yeah, but it requires re-implementing all those tools. If you already have them implemented in D, then it's not a problem, but if you don't or they are closed-source, then import(filename) won't do much good.

You just need a two step build process.

here is to avoid senseless complications.
If you rely on third party tools for code gen, it will be complicated either way. Going this path means that you have to turn the compiler into a full build system. That finds the right tools in the path, gives good error messages if they are absent, that caches results etc.

related to the build process to zero. This would solve a heap of problems.
If we do that, we should carefully design the system. If we introduce the possiblity to execute arbitrary commands at compile time, we've just introduced the next generation preprocessor.

In any case being able to call external build systems is an important part of any build system. -- Bye, Gor Gyolchanyan. --f46d0407160b590c9704c1307f2c Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable <div class=3D"gmail_quote">On Tue, May 29, 2012 at 9:47 PM, Tobias Pankrath= <span dir=3D"ltr"><<a href=3D"mailto:tobias pankrath.net" target=3D"_bl= ank">tobias pankrath.net</a>></span> wrote:<br><blockquote class=3D"gmai= l_quote" style=3D"margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left= :1ex"> On Tuesday, 29 May 2012 at 16:32:17 UTC, Gor Gyolchanyan wrote:<br> <blockquote class=3D"gmail_quote" style=3D"margin:0 0 0 .8ex;border-left:1p= x #ccc solid;padding-left:1ex"> On Tue, May 29, 2012 at 4:02 PM, Tobias Pankrath <<a href=3D"mailto:tobi= as pankrath.net" target=3D"_blank">tobias pankrath.net</a>>wrote:<div cl= ass=3D"im"><br> <br> <br> <blockquote class=3D"gmail_quote" style=3D"margin:0 0 0 .8ex;border-left:1p= x #ccc solid;padding-left:1ex"> Going this path means that you have to turn the compiler into a full build<= br> system.
