Re: Standalone html builder (a la seaside without seaside?)

by Tim Mackinnon

There have been some excellent suggestions in all of this - and I also came across HttpView2 as well. I am a bit spoiled for choice it seems - so will start trying out a few and will report back. We may also use this topic as a follow-on conversation from the UKST talk from Cincom about building web applications, if people have time afterwards. Thanks again everyone.

Hi Jan, Nice work, the "Eleven" framework goes in the direction of what I was experimenting with for Seaside, but instead of trying to introduce that in Seaside without breaking everything else (as I failed to some extent) you went directly to replace and redo most of the stuff there (some with simplifications). It's nice to see that you have ideas like OneTimeCallback and a FormHandler in it, because I had something similar going on. I didn't understand why you have a CSRF list of tokens in the Session. Thinking of Seaside, I think this would be something nice to introduce in Seaside 4.0 :-) Regards!

Re: Standalone html builder (a la seaside without seaside?)

by Jan BlizniÄenko

Hello, I am using https://github.com/JanBliznicenko/eleven for one of my projects. It is also a full framework, yet much simplier than Seaside and stateless and I believe only the HTML building functionality can be used indpendently. Example: htmlObject := HtmlBody with: (HtmlDiv class: 'content' with: (HtmlAnchor new href: 'https://pharo.org'; targetBlank; with: 'Pharo website'; yourself)). String streamContents: [:stream | htmlObject renderFor: nil on: stream] The nil I am passing in the last line is there in place of an ELRequest entity and is not needed for simple HTML tags without custom components. You might check it out. Be aware that my former colleague created it for our specific project and I have never used it in any other place, so I just HOPE it would work like I imagine. It is also not documented or tested at all.

Hi Tim, To build HTML I use the HtmlElement in https://github.com/jgfoster/WebGS <https://github.com/jgfoster/WebGS>.

Lots of good tips in this thread to explore - thanks everyone, Iâll report back on what I find works bestâ¦ To Offray - with a template approach, I have often been tempted with that too but I like the idea of autocompletion and easier refactoring capabilities in Pharoâ¦ but you never know.

Hi, I know this is not what you're asking for, but maybe some lateral thinking could help with your need. Jump to the end for the TL;DR suggestion or bear with me some paragraphs for a practical example. In our project about "IndieWeb with Brea", we use Pandoc and some external tools to produce the web site you see in [1] from Markdown files in [2] combining them with templates done is Mustache[3], as the one in [3a]. Everything is orchestratedÂ by the minimalist Pharo based Brea CMS[4] and produced using interactive Grafoscopio[5] notebooks and stored in Fossil[6] SCM, which proves timelines[6a], user management, permissions and wiki like views of each page (click on the top right corner Icons of each page to see it). It has been a pretty agile experience and kind of our "pocket infrastructures" approach to decoupled/headless CMS, even before we knew about them (and their rising). [1] https://mutabit.com/repos.fossil/indieweb/ [2] https://mutabit.com/repos.fossil/indieweb/tree?type=tree&name=docs/es [3] https://github.com/noha/mustache [3a] https://mutabit.com/repos.fossil/indieweb/doc/trunk/docs/es/pagina.mus.html [4] https://mutabit.com/repos.fossil/brea/ [5] https://mutabit.com/grafoscopio/en.html [6] https://fossil-scm.org/ [6a] https://mutabit.com/repos.fossil/indieweb/timeline [7] https://github.com/pillar-markup/MicroDown We use Pandoc because of historical reasons and because we need YAML metadata headers, multiformat support including PDF export with custom pre-processors (Pandoc filters). But, at some point I would like to use Microdown[7] as a pure Pharo native format when Pandoc is not available or as a replacement/complement for Pandoc filters. So, my lateral thinking suggestion is why not to avoid HTML altogether? Mustache and Microdown could take you far regarding light web deployment and development.

Re: how to check for the statusCode

by Sven Van Caekenberghe

You *really* should read the HTTP chapters of http://books.pharo.org/enterprise-pharo/ in particular https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessf… not just the Web App chapters. Also, any general introduction to HTTP (maybe even https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol) will help you. You can just say response statusLine You also really, really have to learn how to use the tools (the IDE) to help yourself. If you browse the ZnResponse class, you can see all this for yourself. I know there is a steep learning curve, and that it can be intimidating, but the whole idea behind Pharo is that you have this living object system that you can explore and learn from. The introduction texts (Pharo By Example, the MOOC, etc) all try to learn you that. Use spotter to find things, use browsers to look at code, use inspectors to look at objects, use senders and implementers, use class references, read class and method comments, study unit tests. Learn from the system. BTW, ZnEasy is just a simple class side facade, ZnClient is the real thing. > On 28 Sep 2020, at 20:34, Roelof Wobben via Pharo-users <pharo-users(a)lists.pharo.org> wrote: > > Hello, > > Sorry for asking so much questions but I lost the big picture right now. > > Im trying to get the response object back from a api call. > > That I can do with : > > ` response := ZnEasy get: url. ` > > and I see that it has the fields statusline which has the field code > > I thought I could use it like this : response at: #statusline ` > but that give me a error message that indexes needs to be integers. > > How do I get the code field again ? > > Roelof

Re: Standalone html builder (a la seaside without seaside?)

by Esteban Maringolo

I've been playing with something like that, but still using Seaside. I was calling it "WAStatelessApplication", which is nothing but a way to route requests to components, and have these components not using callbacks nor continuations. I'm really comfortable with the Seaside canvas way of doing HTML, so I'll eventually end up building it, but currently it is just another abandoned project. For a very few specific things, I used a RESTful handler and a WABuilder to generate the HTML output, using regular components to render it. Regards! Esteban A.
