ExternalizeImages - having trouble

[Ed Heil]

Hey, new to tiddlywikis, moderatley obsessed.

I have a wiki with some images in it which I'd like to externalize, so I'm looking at the instructions here --

https://tiddlywiki.com/#ExternalImages

and I'm not getting them to work.  What I've done --

create a wikifolder to work in.

tiddlywiki --load mywiki.html --savewikifolder folder

I wrote a shell script to run the commands, like this:

#!/bin/bash

tiddlywiki --savetiddlers '[is[image]]' images

tiddlywiki --setfield '[is[image]]' _canonical_uri '$:/core/templates/canonical-uri-external-image' text/plain

tiddlywiki --setfield '[is[image]]' text "" text/plain

tiddlywiki --rendertiddler '$:/core/save/all' externalimages.html text/plain

Figuring I'd need to quote some of those arguments so the shell wouldn't do anything funny with them.

I run it, and it does indeed create a folder named images/ full of images, but it does *not* set the _canonical_uri field of the images, and it does *not* erase the text field of those images (neither in the tiddlers directory, nor the output/externalimages.html file).  

Is there an issue with the way I'm doing it?  It's a pretty vanilla tiddlywiki. The fact that the first part worked fine (save the images) but the rest of it (convert to canonical_uri) didn't work at all confuses me.

(This is on OS X).

Thanks for any help!

Oh, I thought maybe I should try this with a build target instead of a shell script.

So I looked in the tiddlywiki.com docs for an example of build targets.....  and couldn't find one.

The build *command* is described here -- https://tiddlywiki.com/#BuildCommand  -- but it doesn't talk about how to define build targets....

It refers you to "tiddlywiki folders" here -- https://tiddlywiki.com/#TiddlyWikiFolders "for details of defining build targets."  But there are no details about defining build targets there; build targets are never mentioned.

Under the heading "tiddlywiki.info  Files"  here -- https://tiddlywiki.com/#tiddlywiki.info%20Files  we have the following info:

build - a hashmap of named build targets, each defined by an array of command tokens (see BuildCommand)

Of course, Buildcommand doesn't tell you anything about arrays of command tokens.

I assume from that description, since I know what JSON is and what hashmaps and arrays are, that we're looking for is something like:

{

    "themes": [

        "tiddlywiki/snowwhite",

        "tiddlywiki/vanilla"

    ],

    "build": {

      "externalimages": [

        

      ]

    }

}

where what's in "externalimages" are a list of "command tokens" but "command tokens" are not mentioned anywhere else.

The documentation is pretty unhelpful here.

Welp, of course, as soon as you ask for help in public, you figure it out yourself.

I was reading this, hoping for info on build targets -- https://www.didaxy.com/exporting-static-sites-from-tiddlywiki-part-2

and I saw that there they were using commands like:

tiddlywiki --rendertiddlers [!is[system]tag[Live]] $:/core/templates/static.tiddler.html static text/plain --rendertiddler $:/core/templates/static.template.css static/static.css text/plain

where you throw a bunch of ---commandline --options onto a single invocation of the "tiddlywiki" command.

That was the problem, of course, and once I got rid of the multiple tiddlywiki commands and combined them all into one it worked!

Just discovered that site myself and it's awesome.  Also check out 'the book' I am finding it very informative even as a wip.  Welcome to the obsession!  External Images were always a bit of a conundrum for me as well.

Oh wow thank you!  Putting that at the top of my reading list!
