IceBear - a simple GUI for Data Frames

IceBear - a simple GUI for Data Frames

A simple binary to view parquet files. This allows you to open parquet files in an app by double-clicking them. You can also run simple SQL query on top of the data to see easily what's in there.

Build

Prerequisites

sudo apt install -y build-essential \
  librust-atk-dev libcairo2-dev libpango1.0-dev \
  libgtk-4-dev libgdk-pixbuf2.0-dev

Release build

cargo install --path .

Then you can verify by running:

icebear --help

If that doesn't work, make sure you have ~/.cargo/bin in your PATH.

Associate with parquet files

Taken from stack exchange.

Step 1: Create a new mime type

In /usr/share/mime/packages/ or ~/.local/share/mime/packages/ create a file parquet.xml with content:

<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
  <mime-type type="application/x-parquet">
    <comment>Parquet file</comment>
    <glob pattern="*.parquet"/>
  </mime-type>
</mime-info>

With this xml file in place, update the mime type database:

update-mime-database /usr/share/mime
# update-mime-database ~/.local/share/mime

Step 2: Create a .desktop file for the application

In /usr/share/applications/ or ~/.local/share/applications/ create a file parquet.desktop with content:

[Desktop Entry]
Exec=/path-to-project/icebear/target/release/icebear %f
Icon=/path-to-project/icebear/logo.png
Name=Parquet GUI
Terminal=false
Type=Application

Just change path-to-project in Exec and Icon. We'll move the binary somewhere outside the project at some point.

Step 3: Add logo to the mimetype

This is just experimental. Adding logo in previous step should have worked. The downside is that the project needs to stay at the same location.

export SIZE=256
convert logo.png -resize $SIZEx$SIZE /tmp/logo.png
xdg-icon-resource install --context mimetypes --size $SIZE /tmp/logo.png application-x-parquet
