reading modules broken?

reading modules broken?

[Meer, H. van der]

[-- Attachment #1.1: Type: text/plain, Size: 1424 bytes --]

My modules are not read anymore, allthough Context thinks it does. This must have been the case for some time. I ran a test with an older version which demonstrates that the change in behaviour must have occurred after january second.
Minimal example follows.

Hans van der Meer

Module code in file module-test is:
\writestatus{HVDM}{Module has been read}
\endinput

Test code in file moduletest.tex is:
\usemodule[module-test]
\starttext
module testing look into the log.
\stoptext

In the log I find:

This is LuaTeX, Version beta-0.79.1 (TeX Live 2014/dev) (rev 4972)
 \write18 enabled.
open source     > 1 > 1 > /Users/hansm/tex/context-20/tex/texmf-context/tex/context/base/cont-yes.mkiv

It says the module is already loaded, but the telltale \writestatus is absent.

Running the same code with an older version of ConTeXt does load the module:

ConTeXt  ver: 2014.01.02 20:05 MKIV current  fmt: 2014.1.2  int: english/english

modules have names like

m-
x-
s-
p-
u-

and the lookup happens in a certain order without prefix, and checking 
for mkvi, mkiv, mkii or tex suffixes

so in your case it should be something

u-hvdm-test

or so (user hvdm test)

so you were just lucky that in the past modules-* worked

the loading is probably ok because test.* is loaded

Remark: u- does not work out of the box, only when called as \usemodule[u][modulename].

I had consulted the Wiki that tells us:
Usage
When you load a module with \usemodule[modulename] ConTeXt looks for a file with the following names:

  *   m-modulaname (core module)
  *   p-modulename (private module)
  *   s-modulename (ConTeXt style file)
  *   x-modulename (XML module)
  *   t-modulename (Third party module)
  *   modulename

Once a file is found ConTeXt stops the search and loads the found file (only once).
When you have two file with the same name but different prefixes you can tell ConTeXt which file it should load with
\usemodule[<prefix>][modulename]

I checked \usemodule[modulename] with all these prefixes and they work ok.
But the last item in the list (marked red for clarity) does not (any more). That item suggest \usemodule[module-name] should work. I suggest someone in charge of the Wiki takes a look and removes the last item when my observations turn out to be correct.

A final question. Using the \usemodule[<prefix>][modulename] form, one can use any prefix letter. In fact, any prefix seems to work. If that functionality stays, it will give more flexibility in the naming scheme for modules. Please confirm if this will be the case or if module naming in the future will be restricted to a one letter scheme or even restricted to [mpsxt] exclusively as mentioned in the Wiki.

What’s the meaning of the new “v” prefix for modules?

It is actually an old one (that can go, i had some v files on my machine 
.. collected examples).

In file-mod.lua we have commands.usemodules, and we can extend that to 
support the case where a user has provided some prefix (prefixing 
prevents clashes with files elsewhere in the tex tree)

...
             if status then
                 -- ok, don't change
             elseif find(truename,"%-") and usemodule(truename) then
                 -- assume a user namespace
                 report_modules("using user prefixed file %a",truename)
                 status = 1
             elseif not permit_unprefixed then
                 -- forget about it
             elseif usemodule(truename) then
                 report_modules("using unprefixed file %a",truename)
                 status = 1
             else
                 status = 0
             end
...

Btw, in the case of hvdm, an option would have been:

\enabledirectives[modules.permitunprefixed]

I'm somewhat surprised that the issues show up now as that code is not 
that young.

That new behavior breaks SimpleSlides however, because now the styles 
aren't loaded anymore.
In the log I find (for example):
resolvers       > modules > 'simpleslides-s-BottomSquares' is already loaded

So either this old behavior had it's upsides or SimpleSlides needs to be 
fixed :-)

I have my modules renamed. With x-<oldname> for xml-processors and t-<oldname> for the others. After that everything seems to work fine. No need therefore to change \usemodule calls inside the code.

then better add a -hvdm- too in order to avoid future name clashes

s-simpleslides

would have been a better choice

I have uploaded a new version with these changes, it appears to work. I don’t have time right now to look at all the styles (most work, some have small defects) and do the documentation, so this is just a version patched with the most important changes. And now that the last user of mkii, in a small country in central Europe, has switched, I have made the module mkiv only.
