Project, product, component...

Project, product, component...

[Procházka Lukáš Ing. - Pontex s. r. o.]

[-- Attachment #1: Type: text/plain, Size: 1161 bytes --]

Hello,

I'm trying to use advantages of project/product/component structure.

Suppose having a very simple example (both files in the same directory):

---- Prod.mkiv
\startproduct PPP
   \component Comp.mkiv

   Product
\stopproduct
----

And:

---- Comp.mkiv
\startcomponent CCC
   Component
\stopcomponent
----

When I compile Comp.mkiv, I get (successfully) text "Component".

When I compile Prod.mkiv, I get (successfully) text "Product Component".

So the question - what are "PPP" and "CCC" identifiers (following \startproduct and \starcomponent respectively) used or intended for?

- So far, it seems to me that I refer to file names (as with \input) when working with components rather than their ids assigned by \startcomponent or \startproduct.

What would be a situation when I'd need to use ids "CCC" or "PPP" (or later, those assigned by "\startproduct PROD" and "\startenvironment ENV")?

Best regards,

Lukas

Hello,

Project structure use quite often, but yet similar question not occurred 
to me. I had always previously PPP and CCC as existing filenames on the 
disk. I suppose it would be right.
But I would like to extend Luke's question on this issue:
You can load an existing component to other components? Is it acceptable 
or undesirable? At some point I would throw this possibility, but I do 
not want to do something that could then backfire somehow.


Thanx Jaroslav Hajtmar

It's a very  interesting question, I was asking myself  the same and
I'm curious about  the answer. The ConTeXt magazine  #1101 - Project
Structure¹ is reserved about this topic and simply states:

  “The names given after the start command are not that important…”

I always used filenames, too.

The  ConTeXt  magazine  #1101  includes  a  table  of  the  possible
combinations  of  the commands.  From  this  table I  conclude  that
components are allowed between:

∙ \starttext      \stoptext
∙ \startcomponent \stopcomponent
∙ \startproduct   \stopproduct

Thanx Marco.

I remember that I once read that magazine, but I already forgot it. It 
is good that you reminded me. It is good to occasionally return to the 
forgotten manuals. Thanks again.

Jaroslav.

Re: Project, product, component...

[Procházka Lukáš Ing. - Pontex s. r. o.]

Hello,

as no new answer so far, I started to experiment.

It seems that [at least] component id(s) cannot be omitted:

---- Prod.mkiv
\startproduct % PPP
   \component Comp.mkiv

   Product
\stopproduct
----

And:

---- Comp.mkiv
\startcomponent % CCC
   %\product Prod
   %\project Proj

   Component
\stopcomponent
----

- Gives a wrong product, as Prod.pdf doesn't include the component.

Another test:

---- Prod.mkiv
\startproduct _ % PPP
   \component Comp.mkiv
   \component Comp2.mkiv

   Product
\stopproduct
----

And:

---- Comp.mkiv
\startcomponent _ % CCC
   Component
\stopcomponent
----

---- Comp2.mkiv
\startcomponent _ % CCC
   Component2
\stopcomponent
----

Gives a good result.

So it seems that [at least some] ids are required, and just not-to-be-empty.

I tested the case when all product/component ids were the same, i.e. "_", as a dummy value.

As later the ids are referred nowhere, it seems that they are necessary just due to syntactical rules.

Or - ?

Lukas

they are also used in

- cross document referencing (component processing)
- logging and reporting
- keeping track of loading environments once
- internal pusp/pop states and hashes
- whatever we need in the future

(so, naming all environments _ will load only one)
