Re: [racket-users] What is the right way to generate HTML from the web server?

I'd enjoy a #lang that parses Jinja templates. They've proliferated to all the major web languages and work nicely, so a Racketized version seems like an obvious upgrade. On Thu, Jan 4, 2018, at 3:23 PM, Matthew Butterick wrote: > >> On Jan 4, 2018, at 11:47 AM, Jay McCarthy >>

Re: [racket-users] Intro and projects inquiry

In my experience, it means two seemingly opposite things that unify to create bad software. On the one hand, it's an extreme conservatism and fear of attempting new things. Don't try a new language, just keep using PHP. Don't install the new PHP version with better features, it could be risky.

Re: [racket-users] Intro and projects inquiry

Unfortunately, Whalesong's current fork requires an old version of Racket and hasn't seen a commit to master in several months. Racketscript is under active development, though, and provides a mostly- complete implementation of Racket for Javascript. Seems comparable to Clojurescript in its

Re: [racket-users] using Racket web server behind Apache as proxied HTTPS app server

I use UFW to configure iptables on my server. It's much less error prone than configuring iptables directly in my experience. SSH with key auth and http(s) are the only ways in. https://help.ubuntu.com/community/UFW On Tue, Sep 26, 2017, at 08:10 PM, 'Royall Spence' via Racket Users wrote

Re: [racket-users] using Racket web server behind Apache as proxied HTTPS app server

Yeah, you'll want to allow connections only from the frontend webserver. That's probably 127.0.0.1, but it would be different if you're doing a frontend server with a pool of backends. On Tue, Sep 26, 2017, at 08:04 PM, Matthew Butterick wrote: > >> On Sep 26, 2017, at 3:45 PM, Alexis King >>

[racket-users] Library function naming

Is there a convention on naming library functions? I'm thinking that `library-function-name` is the right way to export functions, but I haven't read enough Racket code to know what qualifies. For example, a "money" library would export functions like "money-convert" and "money-deposit". Does

Thanks for the feedback. I should be able to apply all of these in the next day or two. Regarding the test module and rackunit, the raco package template actually puts two test modules into main.rkt, with rackunit in one of them. This smells like a mistake, right? I'm going to try to find the

Thanks, Jack. It sounds like a great Rackety solution and easy way to get into trying my own languages. I've already started work, though, and the 40 lines of code I've written looks like it'll do the job once I shake out the bugs. On Sun, Aug 27, 2017, at 05:49 PM, Jack Firth wrote: > On Sunday,

Re: [racket-users] Random values in Typed Racket?

Sounds like two questions wrapped into one. When it comes to setting names to values, Scheme programming encourages the use of a "let" expression to bind values to names inside of a (usually narrow) scope rather than assigning a value to a variable. See more here:
