Barliman: Prototype of a smart text editor
If you&#x27;d prefer to take this discussion to email we can.<p>&gt; Thanks for the post, the pull requests, and the questions!<p>You are very welcome, lol. There might be more coming as time permits. I&#x27;ll keep an eye out on the progress.<p>&gt;  I&#x27;m not promising, though, that the answers aren&#x27;t ridiculous&#x2F;stupid! :-)<p>I&#x27;ve always felt like people are too afraid about not sharing their ridiculous ideas anyway :-).<p>&gt; I  suppose the standard answer is: rule-based systems that have to perform some type of logical inference.<p>I think that my question was a bit too ambiguous. I think that I meant like an area where logic programming isn&#x27;t currently commonly used (to me, the network configuration tool seems very out of place for example) but it would be a match made in heaven. I&#x27;m aware of expert systems :-).<p>&gt; In the 1980s logic programming was mainstream, at least in Japan!<p>I&#x27;m actually aware but for some reason it&#x27;s not mainstream now.<p>&gt; What hasn&#x27;t taken off again is a full, general purpose logic programming language, like Prolog.<p>That&#x27;s what I was asking about. E.g. would it make sense to e.g. write an OS in a logic&#x2F;relational language? What sort of CPU support would be required to make this a serious effort? I think what I&#x27;m getting at is that I feel like e.g. Prolog isn&#x27;t truly general purpose. I get that it&#x27;s turing complete but large portion of programs are much slower in prolog (as you say yourself). Is this something that&#x27;s &quot;inherent&quot; to logic languages (like even if HW support were better, will it always (i know i know, no absolutes but you get the gist) be MUCH slower or could it be just slightly slower)?<p>Like I realize that they are slower because they are fundamentally doing a search but I&#x27;m wondering if e.g (and I&#x27;m really just trowing ideas on the wall here) it&#x27;s possible to leverage type systems and hw support to considerably reduce the runtime search space and do most of it on compile time. Are you familiar with liquid types (you mention dependent types, so I&#x27;m guessing yes?)?<p>In your work, you seem to be gravitating towards dynamically typed languages. Wouldn&#x27;t a lot of work be easier in like Haskell or some other type language? I&#x27;m sure you have good reasons for not having switched and I&#x27;m interested in hearing those. Why are Lisps better for your work?<p>&gt; &quot;Never&quot; is a very serious word! :-) I don&#x27;t think we know enough about any form of programming to use words like &quot;always&quot; and &quot;never.&quot;<p>I was actually thinking about wording it slightly less absolutely but I was interested if there were any problems where logic programming would be a bad idea no matter what so it would be basically &quot;never&quot;.<p>&gt; Unless some language&#x2F;killer-application combination appears out of the blue (think Ruby&#x2F;Rails),<p>I think that&#x27;s part of what I was asking. What would be a &quot;killer&quot; app for logic programming? Are there any problems out there that aren&#x27;t currently being solved with logical programming but would really benefit from them?<p>Btw can you recommend some literature on the intersection of logic&#x2F;constraint&#x2F;relational programming and music? I&#x27;ve ordered this book <a href="https:&#x2F;&#x2F;amazon.com&#x2F;dp&#x2F;1848212887&#x2F;" rel="nofollow">https:&#x2F;&#x2F;amazon.com&#x2F;dp&#x2F;1848212887&#x2F;</a><p>I&#x27;ll check out the links you posted. I&#x27;m actually working full-time on this music composition app (logic&#x2F;relational programming isn&#x27;t the main contribution of the application but I&#x27;m just trying to see if there&#x27;s some low hanging fruit I could do easily and blow minds). If you have any sort of input into that I&#x27;m be interested. I saw on your CV that you supervised some undergrad research in this area so I&#x27;m guessing that you might not be unfamiliar with that intersection.<p>I did see like the top google links when I searched for the combination of those keywords (e.g. <a href="https:&#x2F;&#x2F;vimeo.com&#x2F;55677313" rel="nofollow">https:&#x2F;&#x2F;vimeo.com&#x2F;55677313</a>) so I think I&#x27;m interested in some sort of meta analysis.
