Skeletal generator
In advancing to a reload system for Cmsed, I've built a directory skeleton generator[0]. It supports both lua and a simpler text file syntax. An example of this is: # Simple skeleton descriptor dlfile livereload.txt livereload.txt mkdir bin mkdir deps dlfile deps/package.json package.json mkdir dynamic/config mkdir dynamic/models mkdir dynamic/public mkdir dynamic/routes mkdir dynamic/templates mkdir dynamic/caches mkdir static/config mkdir static/models mkdir static/public mkdir static/routes mkdir static/templates mkdir static/caches You can basically do everything you need with the simpler syntax except for conditional and input gathering or manipulation. Regex(find/replace) on files based upon the cli args is possible however. I will be using a variation of this for Cmsed. With regards to lua support, I've hooked up lua's require module system into the providers (github/bitbucket), so it is possible to require any file from a repository and use it as a required module. I've also bound std.file and std.stdio into lua. So it should be possible to do almost anything you need if lua cannot do it natively. [0] https://github.com/rikkimax/skeleton

Thanks for doing it. I like it when people can carry a talk without slides. I've seen a few presenters in my time who were hanging off of PowerPoint, and they always felt so awkward.

I used dmd. i sometimes got the feeling that you underestimate the sheer power of todays clang or gcc optimizers - so partly what gdc/ldc can do with your code reminds me of brian schotts exmaple of his sse2 optimized version of his lexer - the dmd generated was much faster then the normal version, but gdc/ldc results of the unoptimized versions are still 50% faster i understand your focus on dmd - but talking about fast code and optimizing WITHOUT even trying to compare with other compiler results is just a little bit strange for someone who stated speed = money I think this somewhat misses the point of the example, which I would say was - in academia-speak - purely illustrative. The point still stands, which is unless you understand the compiler and the architecture, stop trying to second guess performance on the micro-level

Should any snippets be removed? Added? Any problems with the current snippets? (the wrap in try/catch in the previous version had issues with wrapping indented text, for example) This looks great! A lot better than my non-pythonized snippets :)

Yeah, the top level post seems to work, but comments on other posts, including this one, don't show up. The indirect link plan appears to work though.

Re: DConf 2014: Adam D Ruppe's amazing slideless talk on x86 Bare Metal and Custom Runtime Programming
Plain text transcript of the video (typed up by me, so there may be some errors but the bulk of it should be readable) http://arsdnet.net/dconf-transcript.txt I'll do an annotated HTML version when my schedule permits but for now you can look at the plain text file there (if you don't see it all, try refreshing because you might have last night's version cached) if you want something searchable or don't like videos. I randomly made notes of the timestamp as I typed it up so you can jump to it in the vid too. But, since for the most part it was just me pacing and talking, except for a few points where I used my fingers to illustrate points, you aren't really missing that much sticking to plain text (except for transcription errors). I'll post the annotated version when it is done here too.
