What is the right way to parse non-self-described text files?
Let's say I have a text file like that:
(10.0, 63.0),(11.0, 62.0)
(80.0, 96.0),(80.0, 95.0),(80.0, 94.0),(80.0, 93.0),(80.0, 92.0),(80.0, 91.0),(80.0, 90.0),(80.0, 89.0),(80.0, 88.0)
(58.0, 76.0),(58.0, 75.0),(58.0, 74.0)
Should I use
serde for this? If so which traits should be implemented? Any good example? I there a better way?
I don't think serde has a built-in format for that file format.
I would just write some code to parse it manually. The file format seems relatively simple. I do not think you would gain anything from trying to use a crate to build the parser.
How to get optimal performance and use all cores?
I mean, I'm sure you could do this with nom. If you are already familiar with nom, that might be a good option, but I could probably write a custom parser a lot faster than I could learn to use nom.
As for multi-threading, don't bother. This is not really the kind of task that multi-threading tends to be useful for.
Is not one of the most performant JS parser multi-threaded?
Perhaps, I'm not familiar with that parser. But writing a multi-threaded parser that is faster than a single-threaded one for something like this is probably really really hard. Certainly there isn't a parser crate out there to help you with that.
Aha. I see. Thanks for answer
It parses multiple files in parallel, it doesn't parse one character stream in parallel.
Ah, that makes sense. Parsing multiple files in parallel is not especially difficult.
Maybe you can advise magazines to publish scientific articles about parsing for getting a degree?
Is that possible in the domain of parsers and compilers?
What did I phrase badly?
I don't know anything about scientific articles related to parsing.
Hm. Is that possible to get degree in this domain?
There are probably quite many people whose thesis is about parsers.
Interesting, how do they publish their articles. Is not publishing articles mandatory to get a degree?
That depends on the type of degree. It certainly wouldn't be for a bachelor's degree, but it would be for a PhD.
As for how you publish articles about parsers, well, like any other kind of article. You write up the article, and submit it to a conference or journal that accepts articles on the topic of parsers.
Aha. Where would you look for a list of such conferences and journals?
I would ask someone in academia who works with parsers which conference/journal is appropriate for the article I have in mind. Alternatively, I would try to find recent articles about parsers and look where they are published.
I suspect that many computer science conferences/journals have parsers as one of the topics they publish about.
