Re: [Python-ideas] Why shouldn't Python be better at implementing Domain Specific Languages?

the implementation is very easy just a program and some ifs if you need more complex, just some reading on tokens etc but the first choice is enough if in py competitions people are solving regex like questions and word extractions without knowing they are solving compiler theory problems, implem

Very nice, thank you. It would be a good start to collect usage patterns like this as seen in the wild for design consideration and test cases. > On Aug 30, 2018, at 10:43 PM, Joshua Harlow wrote: > > And mirrored at https://github.com/openstack/debtcollector >

Re: [Python-ideas] Why shouldn't Python be better at implementing Domain Specific Languages?

The word "domain" appears in this sense on the first page of Aho and Ullman and ANTLR (which I know you've used) describes itself as a tool for building domain-specific languages. Both pre-date Ruby I'm fairly sure. James Lu, quoting Jonathan Fine, used the term "internal DSL" and although tha

Executive summary: Although I'm obviously not particularly in favor of this feature, my opinion is no more valuable than anyone else's. The point of this post is to show how features have been advocated successfully in the past. James Lu writes: > > By comparison, > > > > x, y += a, b > >

Re: [Python-ideas] Why shouldn't Python be better at implementing Domain Specific Languages?

i believe a DSL is simple enough for an enthusiastic py programmer to write if you really wanted one just write the tasks you need to accomplish, the data needed, the constrcuts needed (if needed), the feel/look of it on your editor plan first, come up with a good mock, then implement it. impleme
