This is a major overhaul of the hardware abstraction layer.
A few notes:
General platform distinction happens in
frontend/device.lua
which will delegate everything else to
frontend/device/<platform_name>/device.lua
which should extend
frontend/device/generic/device.lua
Screen handling is implemented in
frontend/device/screen.lua
which includes the *functionality* to support device specifics.
Actually setting up the device specific functionality, however,
is done in the device specific setup code in the relevant
device.lua file.
The same goes for input handling.
colors were a mixture of 4bpp integers (0=white, 15=black) and
fractional blackness levels (0=white, 1.0=black) before. This is
now unified to use the color specification of the Blitbuffer API.
This option is useful when creating a PDF file with embedded collection
by the same author. Then one can specify the author on the command line
and it will be shown correctly instead of the email address in Amazon's
Personal Documents area.
1. In extr.c the error message should use the correct full pathname, not
the base filename.
2. In pdfattach the check for existence of input files should be
replaced with the check for read access to them.
1. Emit the list of attached files first and then emit each individual
attachment one per page.
2. Use hyperlinks in the list of attached files so one can jump directly
to the file which he wants to extract.
1. Set the page size to 9x12cm as appropriate for Kindle 3
2. Together with each attachment print its base filename and file size
in bytes.
3. Print the total size of all attachments (so one can estimate whether
it is safe to extract the attachments or not).
1. Handle filenames with spaces
2. Check if pdflatex and attachfile packages are installed before trying
to use them.
3. Use a more intuitive interface "pdfattach -o file.pdf file1.djvu
[file2.djvu]..." instead of forcing the user to specify "-i" option for
every input file.
This utility creates a PDF file containing specified files embedded into
it as attachments. The attachments can be extracted from the PDF file by
using extr utility.
I placed this in a separate "utils" directory to signify that this is
NOT intended to run on a Kindle (it requires pdfLaTeX to generate the
PDF file) but only on the desktop Linux workstation.
