texinfo back-end won't export to INFO

texinfo back-end won't export to INFO

[Thomas S. Dye]

Aloha all,

Export to INFO fails to produce an output file.

Export to TEXI works.  Running makeinfo on the texi file yields errors
like this:

/Users/dk/org/orgmanual//orgmanual.texi:171: `Exporting' has no Up field
(perhaps incorrect sectioning?).

If I run the texi file through (texinfo-all-menus-update), then makeinfo
runs without error and produces an info file.

Perhaps this step should be added to the texinfo back-end?

All the best,
Tom

I think this calls for a new variable `org-export-after-rendering-hook'
which will operate after the final stage of the export process, in the
export buffer.  Filters are fine but their complexity is not useful here.

Then we could add 'texinfo-all-menus-update to this hook.

Nicolas, what do you think?

IIUC, Jonathan Leeche-Pepin fixed this in org-e-texinfo.el a while back.

There is no such thing as an "export buffer" in the new exporter,
`org-export-as' produces a string.

Though, there is `org-export-filter-final-output-functions', which will
operate on the last string produced by `org-export-as'. You may create
a function that will insert that string in a buffer, apply
`texinfo-all-menus-update' and call `buffer-string', and add it to that
filter set.

Note that complexity of filters is the same as hook: you add functions
to a list. A filter function requires three arguments.

org-export-after-rendering-hook for the new exporter? (was: texinfo back-end won't export to INFO)

So let me open a new thread for this possible hook.

Nicolas, what do you think of having `org-export-after-rendering-hook' 
as a simple access for applying global changes on the export buffer?

Does the filter mechanism is simple enough to make this completely
useless?

Thanks!

Okay... thanks for the explanations.

... so that's where complexity comes from.  I'm afraid you'll just 
scare away many users with these three arguments.  

What do you think?

Using a hook or a filter requires to write a function in most cases.
I don't think that a person able to write such a function would cringe
in front of a function of three arguments (you don't even have to use
them all).

Filters are applied on something (often a string). That something is the
first argument. Also, filters are probably very dependant on the
back-end used. That is the second argument. Eventually, it may be useful
to know which options were active at the time of export. This is the
third argument.

I can remove the last argument, bringing down the sum of arguments to 2.
Should I?

No, i think it's good to have such flexible filters.

Let's see if users request a simple generic after-export
(or before-saving-file) hook.

Thanks,
