Quick operations on .fif
files from the terminal:
- preview
- inspect in ipython console
- splits-aware exports and 'saveas'
Ready for integration with CLI-based file managers, such as ranger.
To install quickfif
, run
python3 -m pip install --user pipx
python3 -m pipx install git+https://github.com/dmalt/quickfif.git
The qf
command should now be available in the terminal.
To preview a file:
qfif <filename.fif>
To inspect the file in ipython console:
qfif <filename.fif> inspect
.fif
format doesn't support files larger than 2 GB. To bypass this issue,
large .fif
files are stored in splits: separate files under 2 GB. To keep
track of its parts the first (main) file has to internally maintain filenames
of its parts. It makes splits renaming problematic, since the reanming breaks
the internal filename links. To rename a large .fif
file properly, we need to
read it and then write with a new file name. The following command is a
shortcut for that:
qfif <filename_meg.fif> saveas <dst_meg.fif>
To enable .fif
files preview, in ranger/scope.sh
edit the
extension-handling section:
case "$extension" in
# ...
fif)
try qfif "$path" && { dump | trim; exit 0; } || exit 1;;
# ...
esac
For opening files from ranger
, go to ranger/rifle.conf
and add
ext fif = qfif -- "$1" inspect
