I have looked at YAML off and on over the years, and I'm not sure that it would be much of an improvement in this case.
I do believe that dropping the strict python syntax could make some things easier to read. I don't have a fully-baked proposal in mind, and I don't know what the perf hit would be. I will also note that -- like in many languages -- it's easy to write hard-to-read files. GYP has never had much of a style guide, and it probably could greatly benefit from one. It is important to make a fair apples-to-apples comparison for whatever we end up looking at. I suspect that given any tool or language, you can find some things that are easy to express and some that are harder. Even the existing chromium gyp files are not necessarily a model of clean code or good style. Also, one thing that's important to realize about GYP's syntax is that it is very set-based; the order things appear in the files is much less important than in many other languages (especially in how they handle conditionals, i.e., if/then/else). This has many advantages, but does also have some disadvantages. -- Dirk On Tue, Feb 5, 2013 at 12:16 PM, Eric Seidel <e...@webkit.org> wrote: > I'm curious if YAML was ever considered?
