Re: [tw5] Re: Automatically generating grocery list by clicking on cooking recipes ?

[John D]

/!\ I discovered there is a small issue with my data tiddler editor :
plugins tiddlers are also affected by the viewtemplate ! This is a bit
annoying so here's how to fix it :

replace

<$list filter="[is[current]get[type]match[application/json]]" variable=_>

by

<$list 
filter="[is[current]!is[shadow]!has[plugin-type]get[type]match[application/json]]"
variable=_>

Updated tiddler : download it here


Also please note that this tool will only work with application/json data
tiddler, in the form { "key":"value", "key2":"value2" } (no nested data!)
To create a new recipe, create a new tiddler and set the type to
application/json (or clone an existing recipe).

If you only want this viewTemplate to work for data tiddler with the tag
*recipe*, change the list filter to

"[tag[recipe]is[current]!is[shadow]!has[plugin-type]get[type]match[application/json]]"

"Je batch cook? "  Moi too, et thank le p'tit bébé Jésus parc'que-j'batch 
mange...

Which makes me think right away of "Le Chiac est la solution 
" and something a gal once 
told me:  "ma soeur va shack-é up avec son boyfriend."

BTW: I love "development" with/in TiddlyWiki, from the 
mostly-all-about-data-and-organization (Le P'tit Aurèle 
) to some pretty out-there kind of 
"programming" (BASIC Anywhere Machine 
).  The stuff that can 
be done with TiddlyWiki is really amazing.

But collaborative "development" via forums?  Yeah, that's major heartburn 
for this kid.

@Mat : I'm keeping the NewTids macro in my mind for future use, it does

I work in a field which sometime is a bit taxing mentally and I find doing 
simple repetitive task help me allievate the stress haha.

@Stobot : thank you for the files ! I imported both yours and John D 
methods and while Télumire's is more completed, I really like your idea and 
how you formated it ! I think it can be pretty useful for a lot of 
situation.
As a total newbie, TW was a bit hard to get into at first. I watched a 
serie of tutorial video and read some more to only begin to have a normal 
functionnal TW.
Your idea of incremental tutotal could be a great way to facilitate the 
appropriation of the TW for beginner !

@And finally Télumire/John D : thank you a lot for all your work ! I tested 
it and it worked just fine. It answers to all my problem and more haha.
Reading the programing behind was very interessing ! I understood where it 
comes from (but I never could have written it as easily as you and not for 
a bit of time).
Thank you as well for the ressources you listed. I will read it to optimize 
my utilisation of TW which is such a great tool but I only scraped the 
surface.
The Data Tiddler Editor you writted was way way way too complicated for me 
to understand but I can really appreciate what it does ^^ !
Anyway, thank you again !

With thing as they are now, I guess I can do a pretty good version of the 
TW I imagined. I will maybe post it here when it will be a bit fuller but 
I'm french so all the tiddly/recipe/ingredient would be too. Not sure if it 
could help someone without the book (which is "Je batch cook toute l'année"

Thank you all again !

 @Cass, at first tiddlywiki seems a bit weird in its logic, the best 
 advice I can give you is to search for system tiddler and see how 
 everything is done :) I also highly recommend you to read 
 GrokTiddlywiki , it's a very good 
 book (the chapter Variables, Macros, and Transclusions 
 
  
 in particular should give you all the info you need).

 To sum it up : filter expressions can be used either as-is in widgets 
 with a filter attribute (like the list widget, set widget, etc), or as a 
 filtered 
 transclusion  
 (between {{{ }}}).

 From what I understand in the pure logic form (correct me if I'm wrong)

 Yup, that sounds about right ! You may need to nest several list widget 
 but it should be possible to do it for each ingredient in one filter. Also 
 you may need to use the indexes Operator 
 to get the list of 
 ingredient name in a data tiddler

 I don't have a lot of time right now 

[tw5] Re: Automatically generating grocery list by clicking on cooking recipes ?

[Mat]

Feeding in individual food items into TW is a tedious task. *IF* you intend 
to do this, may I recommend the NewTids macro 
.

 Example of something to keep in mind: if a recipe calls for 100grams of 
 onion, you'll want to convert that into something useful for grocery 
 shopping.

 Probably good to instead talk about a measure of an onion for 
 groceries.  You won't be buying a 100 g onion, so you'll want to have 1 
 onion, regardless of size and know you'll have left-over onion for your 
 omelette the next day.  Because you need about 1/4 of a small onion, or 
 whatever  of a big onion.

 But if you need an amount of grams o' onion that requires a large 
 onion, then you'll want a way to say a large onion.  Or two small onions.  
 Or whatever.  Knowing you'll be doing a little bit of rough math at the 
 grocery store.

 Your grocery list will get messy if you have 1 small onion and 1 large 
 onion when the onions are in a bag.

 All of that to say, don't be to quick to start building everything in 
 TW until you can visualize (spreadsheet or whatever) get a somewhat 
 reasonable amount of "stuff" for the big picture.

There are loads of ridiculously adept TiddlyWiki folk who can help you out.

I'll have to bail, because trying to help out with this kind of thing via 
any forum is way too chaotic and disorganised for me to contribute towards 
the development of good stuff.  (Information Systems/Business Analyst and 
software developer I am, but I have a cognitive disability and quickly

I look forward to seeing the end-result, because what you have in mind is 
an awesome use-case for TiddlyWiki.

[tw5] Re: Automatically generating grocery list by clicking on cooking recipes ?

[Cass P]

Thank you all for your answer !

@CJ : for the practical aspect of the grocery list, I already have a pretty 
good idea of the function I want as I'm already be using the book for quite 
some time. The serving doesn't need to be adapted.
Most ingredients are either in gram or in unity (for exemple, most of the 
vegetable is indicated as "two onions". Pasta or rice are indicated in 
gram).
I am confortable enough with the recipes and cooking in general to adapt 
which type (volume) of onion I need even if it's roughly indicated I need 4 
onions.
The biggest problem for me right now is the programming part as I have no 
education in the matter unfortunately haha.

@Télumire : thank for the proceding, I did understand the reasoning but I'm 
having troubles for implementing it.
As said just now, I don't have a good programming knowledge and I think the 
most I knew where how to print the famous HelloWorld haha.
For now, I did create the  data tiddler for all recipes of week 1.  I did 
implement a simple multiple select but with no function in it because I 
can't write it.

>From what I understand in the pure logic form (correct me if I'm wrong) : 
I need to write a formula which will take into account which data tiddler I 
selected in the multiple select. With selected data tiddlers, I will need 
to show the name property with the index value associated (which I need to 
get with getindex). In case there are multiples same named property, I need 
to use the function SUM.

One big obstacle for me is how to use operator in Tiddlywiki. Just 
copy-pasting the formula doesn't seem to work because I guess I need to put 
something to tell Tiddler that what I'm writing is a formula. Until now, 
using the bracet [] for simple list were enough. I think I don't know the 
basic of the basic to implement formula in my tiddler. 
Do you have a good ressource to learn from ? I saw TW page for developper 
but I don't know if it's adapted. Ressources with already written formula 
from which I can inspire myself is a big help too ^^ (for example, a 
pratical use of the getindex in action and not in the example of the TW. If 
not, it's okay !).

I am not in hurry, it's more of a fun side project so learning it to do it 
myself could be benefical in the long term if I want to use Tiddlywiki more 
^^ !

[Álvaro]

As they said, you have to think about how save the ingredients of the 
recipe in the tiddler, you can use the index of a data tiddler for recipe 
or simply the field of a tiddler for recipe. 

Then you would need to use the filters  
and their operators. You will need to retrieve the data for your grocery 
list.

[tw5] Re: Automatically generating grocery list by clicking on cooking recipes ?

[Charlie Veniot]

Example of something to keep in mind: if a recipe calls for 100grams of 
onion, you'll want to convert that into something useful for grocery 
shopping.

Probably good to instead talk about a measure of an onion for groceries.  
You won't be buying a 100 g onion, so you'll want to have 1 onion, 
regardless of size and know you'll have left-over onion for your omelette 
the next day.  Because you need about 1/4 of a small onion, or whatever  of 
a big onion.

But if you need an amount of grams o' onion that requires a large onion, 
then you'll want a way to say a large onion.  Or two small onions.  Or 
whatever.  Knowing you'll be doing a little bit of rough math at the 
grocery store.

Your grocery list will get messy if you have 1 small onion and 1 large 
onion when the onions are in a bag.

All of that to say, don't be to quick to start building everything in TW 
until you can visualize (spreadsheet or whatever) get a somewhat reasonable 
amount of "stuff" for the big picture.

This process will help you decide to what degree of complex you want, and 
how/what/where to simplify when you don't want to get that bogged down in 
complexity, yadda yadda.

[tw5] Re: Automatically generating grocery list by clicking on cooking recipes ?

[Charlie Veniot]

G'day,

Whatever you are thinking, start by forgetting about TiddlyWiki for now.  
Put on a "systems/business analyst" hat, and think "information modelling", 
what is the end-result you want, and then start going backwards, figuring 
out what information you need to get to the current stage you are looking 
at.  The current stage is information transformed somehow from some state 
in a previous stage.

And you keep going back and back and back, towards the raw data that 
however many stages back.

Consider using a spreadsheet, the first columns of which are the end result 
you would like.  Then it columns after that, the information as it probably 
needs to be before, and how it gets transformed to the current.

For example, say onions is in your grocery list for this week.  How do you 
figure out how many onions?  The number is based on how many onions you 
need for each recipe you are making this week.  But it is also based on how 
many servings of each recipe.  If some recipe normally calls for 1 onion to 
serve two people, but you are having two other people for supper, then you 
need twice the amount of onion.

But in the grocery list you print out, before going to the store, you might 
check your onion inventory in the fridge.  And you remember you picked up a 
whole bunch of onions last time because they were on sale.  So you realize 
you don't need as much onion, or maybe none at all.  So you will scratch 
some notes on your printed grocery list to adjust the numbers.

So mock-up a grocery list for some week, and figure out the steps to get 
from recipes and ingredients to a tidy grocery list.  What information do 
you need, and what are the transformations from A-Z.

Yeah, may not seem like fun, but I love that kind of stuff ...

[tw5] Re: Automatically generating grocery list by clicking on cooking recipes ?

[Télumire]

You could do it like this : 

Create a data tiddler for a recipe with a quantity associated to each 
ingredient. To make things easier the unit will be hardcoded in grams (or 
whatever you like, but always the same).

Then you can select your recipe for the week with a select widget for 
example (https://tiddlywiki.com/#SelectWidget), use the data of the widget 
in a list widget (https://tiddlywiki.com/#ListWidget) which will sum the 
values of each unique index accross the data-tiddlers you selected.

I think you will need the count Operator 
(https://tiddlywiki.com/#count%20Operator),  getindex Operator 
(https://tiddlywiki.com/#getindex%20Operator),  sum Operator  
(https://tiddlywiki.com/#sum%20Operator). Good luck and let me know if you 
need help to understand something :)
