It's such a pity that so many dub packages are not in friction-free mode. For this particular problem, maybe before it get fixed, can we add to the vibe.d doc suggesting people develop web-server on a virtual machine (e.g. VirtualBox): at least it can reduce some friction to reboot the (virtual) machine more easily.
Reading from stdin significantly slower than reading file directly?
Hi, Relative beginner to D-lang here, and I'm very confused by the apparent performance disparity I've noticed between programs that do the following: 1) cat some-large-file | D-program-reading-stdin-byLine() 2) D-program-directly-reading-file-byLine() using File() struct The D-lang difference I've noticed from options (1) and (2) is somewhere in the range of 80% wall time taken (7.5s vs 4.1s), which seems pretty extreme. For comparison, I attempted the same using Perl with the same large file, and I only noticed a 25% difference (10s vs 8s) in performance, which I imagine to be partially attributable to the overhead incurred by using a pipe and its buffer. So, is this difference in D-lang performance typical? Is this expected behavior? Was wondering if this may have anything to do with the library definition for std.stdio.stdin (https://dlang.org/library/std/stdio/stdin.html)? Does global file-locking significantly affect read-performance? For reference: I'm trying to build a single-threaded application; my present use-case cannot benefit from parallelism, because its ultimate purpose is to serve as a single-threaded downstream filter from an upstream application consuming (n-1) system threads.

With every release it is worse than before and it seems there is almost no activity. So D really need new champion here maybe hunt will be next champion.
Re: How to compile Windows exe files from this source

Unfortunately, the author didn't create any MS Windows binaries: https://github.com/eBay/tsv-utils/releases Does anyone know how to compile this code into MS Windows binaries? It is a bit off-topic but I strongly suggest that you take a look at the windows subsystem for Linux, that is a on-board feature in Windows 10 (https://www.microsoft.com/en-us/p/ubuntu/9nblggh4msv6?activetab=pivot:overviewtab) It makes working with tools like tsvutils much more effective.
