Correct me if I'm wrong but SQLite-D is a compile time SQLite3 file reader. If so, I can predict not many common parts. Maybe the one would be a data deserialization component however I didn't check how it's done in SQLite-D. With has similar goals albeit file format compatible to SQLite. When I was selecting possible file format I was thinking about SQLite one. I am actually a fan of the SQLite project. However there are some shortcomings present in current SQlite3 format: - SQlite3 is not really a one file storage (i.e. journal file) - it gets fragmented very quickly (check out design goals for SQLite4) - it's overcomplicated and non deterministic with respect to real time software - it has unnecessary overhead because every column is actually a variant type Add to this the main goal of replacing SQL with D ranges+algorithms. In result it turned out it would be great to have an alternate format. BTW. Would someone be so kind and post the above paragraph on Reddit under a comment about Sqlite db. I'm not registered there.

One of major concernc behind discussion that resulted in Atila reggae effort is that propagating additional third-party dependencies is very damaging for build systems. Right now Button seems to fail rather hard on this front (i.e. Lua for build description + uncertain amount of build dependencies for Button itself). Building it only requires dmd+phobos+dub. Why is having dependencies so damaging for build systems? Does it really matter with a package manager like Dub? If there is another thread that answers these questions, please point me to it. The two dependencies Button itself has could easily be moved into the same project. I kept them separate because they can be useful for others. These are the command-line parser and IO stream libraries. As for the dependency on Lua, it is statically linked into a separate executable (called "button-lua") and building it is dead-simple (just run make). Using the Lua build description generator is actually optional, it's just that writing build descriptions in JSON would be horribly tedious.

I think the Makefile converter is probably the coolest thing about this build system. I don't know of any other build system that has done this. The only problem is that it doesn't do well with Makefiles that invoke make recursively. I tried compiling Git using it, but Git does some funky stuff with recursive make like grepping the output of the sub-make. - Can automatically build when an input file is modified (using inotify). Nope, I never found that interesting. Possibly because I keep saving after every edit in OCD style and I really don't want things running automatically. I constantly save like a madman too. If an incremental build is sufficiently fast, it doesn't really matter. You can also specify a delay so it accumulates changes and then after X milliseconds it runs a build. - Recursive: It can build the build description as part of the build. I'm not sure what that means. reggae copies CMake here and runs itself when the build description changes, if that's what you mean. It means that Button can run Button as a build task (and it does it correctly). A child Button process reports its dependencies to the parent Button process via a pipe. This is the same mechanism that detects dependencies for ordinary tasks. Thus, there is no danger of doing incorrect incremental builds when recursively running Button like there is with Make. - Lua is the primary build description language. In reggae you can pick from D, Python, Ruby, Javascript and Lua. That's pretty cool. It is possible for Button to do the same, but I don't really want to support that many languages. In fact, the Make and Lua build descriptions both work the same exact way - they output a JSON build description for Button to use. So long as someone can write a program to do this, they can write their build description in it.

This might provide useful information if you're aiming for
something like sqlite (hopefully not offtopic):
https://github.com/cznic/ql
It's an embeddable database engine in Go with goals similar to
yours and at an advanced stage.
