[tw5] Minimal Tiddlers (2) to run BASIC in TiddlyWiki

[Charlie Veniot]

Drag the attached into a TiddlyWiki (TiddlyWiki.com !) to see the very 
minimal architectural needs to run wwwBASIC programs.

Although there isn't much to it, it might give you all kinds of ideas of 
stuff you can do, wwwBASIC or otherwise.

[tw5] Prepping a BASIC Anywhere Machine "architecture" presentation, suggestions?

[Charlie Veniot]

I'd like to put together a comprehensive slideshow for a presentation on 
YouTube.

Although pretty much just a blank page at the moment, I figured might as 
well publish the slideshow document 

 
now, in case there is a soul out there that is interested in this kind of 
thing, and might want to suggest things that would answer questions, or 
what-have-you.

So... the output in that link is a js function and some more stuff that 
wraps the JSON. So, do you *scrub off* the wrapping stuff to accss the 
clean JSON content or do you *use* the js function in your own code? ...and 
is the scrubbing or use of the js function what you have in your tidder 
under "Начало нового кода" ?

This looks very interesting. If I interpret these docs 
, 
it seems very direct to both get and post content from and to a sheet 
(which is one big limitation in the current TiddlyGoo solutions; there is 
no solution to push data to a sheet from TW). 
But, @Siniy-kit, you currently don't use doGet or doPost at all, right? You 
solve *both* push and pull with JSONP, right?

Thank you for your replies.

[tw5] Re: Method of using "nth-child(even)" with ""?

[Álvaro]

If you know the line-height in pre element you can use it to create your 
custom background with repeating-linear-gradient.
In the vanilla theme the (inherit) line-height is 20px, then you can use 
something like this
```
pre {
background: repeating-linear-gradient(#f5f5f5, #f5f5f5 20px, #e0e0e0 20px, 
#e0e0e0 40px);
}
```

No, JSONP is working all over the world (not only in Russia)
3) Old variant  with alt=json-in-script is not working now, *BUT we have 
two another ways*

1) very very very old JSONP (*I use it now*)
https://spreadsheets.google.com/tq?key=16jpYS8egNJuLA8HyS-Um6wuwC9A5eFl-IKykIzZB92Y=goods
here we have js function  with JSON 
argument. google.visualization.Query.setResponse({..})

2) new variant with doGET() in google script
