<amz3`>actually parsing a big than RAM xml file is possible in guile

<amz3`>without any addition :)

<amz3`>ssax parser can do it

<amz3`>the problem is that it's much slower than libxml

<amz3`>wow... this is very slow, I need to test against master to see what happens

<wingo>are you sure the input port is buffered?

<amz3>wingo: I don't know

<wingo>did you open the port from a file? in that case it is probably buffered appropriately and buffering isn't the problem

<wingo>if it's a socket the port is probably unbuffered by default and you need to `setvbuf' on it

<amz3>it's file port

<amz3>it's a file port

<civodul>also make sure to open it as utf-8

<wingo>or at least not ascii :P

<civodul>i'm saying that because utf-8 decoding has a fast path on 2.0

<wingo>yeah and ascii is oddly a slow path on 2.2

<janneke>woot, mes finally runs define-syntax and syntax-rules and based or & when macros

<janneke>ACTION is *happy*

<amz3`>:)

<galex-713>What is the most efficient way to store s-exps?

<galex-713>sql or mongodb?

<galex-713>Because just storing their raw text representation, especially with really repetitive symbols and fixed data type structure, would take probably too much room

<ijp>I don't really understand the question

<galex-713>like, if I want to make a voxel-sandbox game where every block is a sexp

<galex-713>If I just store an ascii sexp for each block it will take a looot of room

<galex-713>so I’d like a way to store sexp, but in binary and compressed form

<galex-713>Yet having good db perf

<ijp>neither of your options sound particularly good

<galex-713>?

<galex-713>what options?

<daviid>galex-713: not answering your quiz, but afaict we do not have mongodb bindings, and more importantly, it is not free s/w

<ijp>how is it not free software?

<daviid>i might be wrong, but i kind of remember someone wrote about mongodb not being free s/w, sorry if it is, i did not check and have confused with another db engine

<PuercoPop>galex-713: checkout conspack

<PuercoPop> https://github.com/conspack/cl-conspack

<galex-713>PuercoPop: is it of the same order of efficience of mariadb/mongodb dbs?

<ijp>measure first, no point committing to a complicated persistence solution otherwise

<amz3`>ijp: that's what I'm figuring out

<amz3`>galex-713: how do you want to reason about the stored sexp will also drive your choice

<amz3`>what do you plan to do with the sexp?

<amz3`>eval it?

<daviid>amz3`: did you not wrote here a little while ago that mongodb was not free?

<daviid>"MongoDB Download Center: Develop your next application with our enterprise products, free for evaluation and development." does not sound particulalr y GPL to me

<amz3`>mongodb is AGPLv3 https://github.com/mongodb/mongo

<amz3`>daviid: no

<daviid>ok tx

<PuercoPop>galex-713: sorry, wrong channel completly

<PuercoPop>it is similar to BSON but for sexps. You can use it as inspiration. MongoDB is neither efficient nor effective though

<daviid>hum. ".. most of the mongodb source files are ... AGPL. files in the client/, debian/, rpm/, utils/mongoutils, and all subdirectories thereof are made available under the terms of the Apache License, version 2.0", which is incompatible with both GPL2 and GPL3, afaict

<daviid>ok

<amz3`>ah ok
