Hello,
I have been working on braille embosser support for CUPS, so that
embossing a document can be as easy as printing it. I have attached the
result.
The principle I have followed is to use the cups architecture to
separate on one hand frontends which turn documents into braille text
(text/vnd.cups-brf) or braille graphics (image/vnd.cups-brf), notably
based on liblouis, and on the other hand backends which emboss braille
text or braille graphics (I have implemented a generic driver which
should work on all embossers, and a driver for the Index embosser which
I can actually test).
For now, I have made a separate package, so it is easy to test it
already, but ideally, I would like to see this work integrated into CUPS
filters, so that blind people don't need to install a separate package,
but just configure CUPS for their embosser. How should we proceed?
Perhaps first iterate over the packaged version, until the code is fine
for integration, and then I'll submit a patch against cups-filters?

Hi,
Thank you very much for this great effort. This is really missing in the
Linux operating system.
I am looking into integrating it into cups-filters, but I would like to
have the following improvements on it:
1. PPD files: If there are different options, like LibLouis2, libLouis3,
... their name translations/long names should also be different, not
having "Additional Braille transcription" for all of them, but rather
"Additional Braille transcription (2)" for LibLouis2, "Additional
Braille transcription (3)" for LibLouis3, ... Otherwise it is rather
confusing having several options showing with the same name in a print
dialog.
2. Cluttering of /usr/lib/cups/filter/: This directory should only
contain the actual CUPS filters (executables called by CUPS in the
filter chain for a job. The auxiliary files should go into a separate
directory, like /usr/share/cups/braille/ (if there are no
architecture-dependent executables or libraries) or
/usr/lib/cups/braille (if there are architecture-dependent executables
or libraries).
3. Binary bytes in shell scripts: Some scripts, like
drivers/index/textbrftoindexv3 contain binary bytes. This leads to
problems with version control systems like GIT or BZR. Please avoid any
binary bytes in scripts or source files, generally in any file contained
in the source tarball. There are ways to express this with pure text. Or
do everything in C (this is even better), there are for sure ways to
avoid binary bytes.
I am grateful if you could fix that.

Right. I'll use bash's $'\015' then.

I had been wondering about turning these into C indeed, but the shell
version seems to me easier to read and maintain actually.

OK, thanks. So please go ahead with the fixes.
And I am also grateful if you do the maintenance of your code when it is
in cups-filters as I do not know much about Braille embossers and also
do not have such a device available to me.
How are Braille embossers connected and how do they appear for the
computer? Do they work with the standard usb/parallel/socket/ipp
backends of CUPS?

Here is an updated tarball.
BTW, which licence would it be better to release this code under? I'm
fine with most free software licences.

Sure! That's what I planned. I'll probably try to contact other
braille embossers manufacturers to get protocol or even devices. Index
is very common in Europe, so it is good enough for a start.

Yes, they really look like usual printers. Just configuring them as
generic text printers would work for instance. In the case of Index
embossers, they have serial, USB (line-printer interface), and network
(HP JetDirect) support.

OK, then no new backends are needed.

Here is a tarball with fixed copyrights. I have also moved the shell
helpers to /usr/share instead of /usr/lib since they are
architecture-independent.

Thank you very much for the tarball.
I have integrated your software in cups-filters now and committed it to
the BZR repository. Please download and try, and tell me whether
everything is working.
I have the following remarks:
- I have integrated your files into the build system of cups-filters
following all free software standards. Especially the configure script
of cups-filters checks the presence of liblouis and also takes an
"--enable-braille"/"--disable-braille" command line option pair. with
Braille support being enabled by default if liblouis is present. Paths
in the scripts are fitted to the system by configure, therefore the
scripts in the source are *.in files with "@...@" placeholders.
- PPD files are not pre-built by the Makefile. The *.drv and *.defs
files are put into the standard places in the CUPS directories, so that
PPDs are generated on-the-fly.
- Documentation of the README and TODO files is joined to the README
file of cups-filters.
- Your name is in the COPYING file now.
- There are three files which I have dropped as they do not get used (no
reference to them in the other files): drivers/generic/fr.po,
drivers/index/fr.po, and drivers/index/ubrlto4dot.c. For what are these
files used, especially what does drivers/index/ubrlto4dot.c do?
- I have dropped the debian/ directory. Upstream packages should never
ship a debian/ directory, independent if it contains the files for
generating Debian packages or something else.
- The Generic embosser PPD file passes cupstestppd, the files for the
Index printers not. The error message is:
**FAIL** Multiple occurrences of option IndexTable choice name 24.
and indeed the option "IndexTable" has two choices with "24" as short
name. As I do not have the printers, I do not know how to fix this
correctly. Can you fix this? (Found by running the command
"/usr/lib/cups/daemon/cups-driverd cat drv:///indexv4.drv/ibrlbox4.ppd |
cupstestppd -" on a system with the current state of the cups-filters
BZR installed).
Thanks again for your great contribution.

I have found out for what the fr.po files are good for: If I put them
into /usr/share/cups/ppdc/ directory, the on-the-fly-generated PPD files
get a French locale added. Only problem is that only one fr.po can be
placed in /usr/share/cups/ppdc/, so I will look into renaming them and
add the two renamed files to cups-filter. I assume I have to rename the
references in the *.drv files appropriately then.
Is this correct?
So the only file staying unclear to me is drivers/index/ubrlto4dot.c.
For what does this file serve?

Good :) I was lazy to do it in my prototype cups-braille package :)

Oh, I didn't know cups was able to do this. Even better then.

Yes; that's very useful.

Yes, please do. Actually I was suprised that the documentation tells to
use "fr.po" name, since as seen by this conflict they have to *not* have
that name :)
Actually they could even be merged, that'd be better since otherwise
there would be a lot of duplication. I have attached the resulting
merge.

This file is used to generate the translation table in
drivers/index/imageubrltoindexv[34]. I felt it was good to integrate it
as "source code" for them, even if actually running the generation in
Makefile is more tedious than really useful.

Sure, no problem.

Oops... I must admit I didn't test polish & dutch braille since I speak
them and don't have an index4 device :) I have attached a patch.

It seems my mailer simplified the encoding of the attachment, thus
turning the file into latin1 instead of utf-8. Here is a patch.

It seems I didn't test enough the case where the user didn't select any
braille translation to let the embosser do it. The attached patch fixes
that case: since we just use fmt to render the text, we need to make
converters emit pure text, not xml.

A second change which will be useful is as attached: for now imagemagick
introduces some header in the produced braille-formatted images. We
will however probably want to remove it in the future. The attached
patch makes cups-filters cope with both the header being present or not.

Hello,
I haven't had time to work on braille embossing support in the past
months, I thought I should just write down my remaining TODO ideas, so
they don't get lost :)
Could the attached file be put in the following directory?
