[BRLTTY] brltty-friendly spreadsheet program

[Nicolas Pitre]

If any of you have been looking for a text-mode brltty-friendly 
spreadsheet program to do your accounting or any other task for which 
such a program could come handy then I have good news for you.

I was actually looking for such a program myself, and I found sc-im:

  https://github.com/andmarti1424/sc-im

However it was far from being braille display friendly. I took upon 
myself to fix that issue plus a few others and I contributed my changes 
to the maintainer. They're all merged upstream at this point.

No binaries are available, at least not with my latest changes. So 
you'll have to compile it yourself. To do so, here's what you should do:

git clone https://github.com/andmarti1424/sc-im
cd sc-im/src/
make
sudo make install

To configure it so the braille display follows the active cell 
automatically, create the file ~/.config/sc-im/scimrc and add this line:

set show_cursor=1

Alternatively you may start sc-im with the --show_cursor command line 
argument. For those who are familiar with the lynx and alpine argument 
of the same name, this is no coincidence.  ;-)

That's it!

Of course a lot can be customized with sc-im, so one of the first 
command you should type once the program is started is:

:help

One additional setting I suggest adding to ~/.config/sc-im/scimrc is:

set newline_action=0

By default newline_action is set to 'j' which moves the active cell down 
after every entry which I personally find confusing.

It is apparently possible for sc-im to read and write Microsoft Excel 
files but I didn't test that out.

Enjoy !
