Not a fan of handling it that way. Shift-reduce conflicts don't correspond to people's intuitive understanding of the grammar because good shift-reduce parser tables are highly non-local as they're constructed from fixed-poin

For unrestricted CFG parsing, shift-reduce parsing does require backtracking. A modern parsing algorithm like GLR uses LR tables but has to resort to backtracking when it encounters shift-reduce conflicts (it avoids the exponential blow-up

Thanks, I didn't know about the GUD rewrite. After I wrote my post above, I started work on a GDB mode from scratch. So far, I have the process management and a PEG-based parser (peg.el is great) for MI output working. I'm not sur

The QtCreator debugger is actually pretty decent, and I prefer it to gdb -tui and cgdb. The debugger in the early-access version of CLion looks promising, but it lacks essential features like a disassembly view and a memory view, and sadly

If you care about optimizing your C/C++ code, you need to be reading the assembly language output from the compiler on a regular basis. You will constantly stumble over cases where the compiler isn't doing what you expected. For e

by psykotic 12y ago
You can easily write a fixed-point combinator for this: https://gist.github.com/pervognsen/eca3bc833a65195f053c . The way you tie the knot in C++ type recursion is not that different from in other languages like Haskell

If the mass objects have trivial (ignorable) destructors and don't own any heap-allocated subobjects then it's not a problem. You can have top-level objects like levels or documents or sessions own everything directly and indirect
