Project & automatic lookup for included directories

Project & automatic lookup for included directories

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

Hello,

I have a product file which includes an environment file placed two directories up.

What is the default lookup of \environment? I thought it were at least one level up, but I'm not sure.

My code so far is:

----
\usepath[{.,..,../..}]

\environment _e-Geom.mkiv % In fact in '../../_e-Geom.mkiv'

\startproduct *
   AAA

   \section{SSS}
\stopproduct
----

The code works; but what members in '\usepath[{.,..,../..,../../..}]' are really necessary (so what lookup is performed automatically? - '.' = the current directory? and/or '..' = the parent directory?)?

Suppose having 3 files:

_e-Geom.mkiv
../_e-Geom.mkiv
../../_e-Geom.mkiv

Which of them will be used when I write '\environment _e-Geom.mkiv' and

a) I specify explicitly \usepath[{../..}]?
b) I don't use '\usepath'?

TIA.

Lukas

A little experimentation shows the lookup order is as follows, from
highest to lowest priority:
current directory,
parent,
grandparent,
whatever is in \usepath.

current directory, parent directory, grandparent

_e-Geom.mkiv will be used in both cases.

Does anybody know if there is a way to specify a lookup path that has
higher priority than the default lookups? I don't know one myself.

Cheers,
Sietse
