>I just wonder if it is possible touse in brltty braille tables from
>liblouis?
Yes, and no. The software to load a liblouis braille table comes with the
brltty source but isn't included within the brltty executable. It is, however,
part of brltty's ttbtest utility, so it's possible to convert a liblouis
braille table to a brltty text table. Support for liblouis braille tables is
incomplete in that it doesn't support characters which require more than one
braille cell.
>And, if it is possible, can anyone tell me, how to do that?
First, you need to download and configure a brltty source tarball. See brltty's
download page for details, and do feel free to ask if anything isn't clear. The
quick summary is:
# use your web browser to download the latest release (4.1) of brltty
tar xfz /path/to/brltty-4.1.tar.gz
cd brltty-4.1
./configure -q
Alternatively, you could check out the latest development source from brltty's
source repository, and then prepare and configure it. The quick summary is:
svn checkout svn://mielke.cc/svn/main/brltty
cd brltty
./autogen
./configure -q
Next, you need to make the ttbtest utility. You do that like this:
cd Programs
make -s ttbtest
# this will create the ttbtest executable within the Programs subdirectory
Now you can convert the table, like this:
/path/to/ttbtest-executable -T/path/to/liblouis-directory name.ctb name.ttb
liblouis-directory is the directory containing the liblouis braille tables.
name.ctb is the liblouis braille table that you'd like to convert.
name.ttb is the brltty text table which will be created.
The brltty text table is created within the current working directory.
