votable-cli 0.2.0

Command-line to convert IVOA VOTables in XML, JSON, YAML and TOML

votable-cli or VOTCli

A command-line to read and convert VOTables from/to XML, JSON, TOML and YAML.

Status

The library this CLI is based on is in an early stage of development. We are (reasonably) open to changes in the various format, e.g.:

• we could flag attributes with a '@' prefix
• we could use upper case elements tag names
• we could remove the 's' suffix in elements arrays
• we could change the pos_infos name for something else
• ...

More testing is required, especially the bit type and arrays. Please, provide us with VOTable examples!

Install

From pypi for python users

VOTable cli is available in pypi, you can thus install the vot executable using pip:

pip install votable-cli
vot --help

Debian package

Download the last votable-cli_vxx_yyy.deb corresponding to your architecture (x86_64_musl has the most chances to fit your needs) from the github release page.

Install the .deb by clicking on it or using the command line:

sudo dpkg -i votable-cli_vxx_yyy.deb
sudo apt-get install -f

Then you can use the tool:

vot
man vot

You can uninstall using, e.g.:

sudo dpkg -r $(dpkg -f votable-cli_vxx_yyy.deb Package)

Pre-compile binaries for MacOS, Linux and Windows

Download the last vot-vxx_yyy.tar.gz corresponding to your architecture from the github release page. You probably want ot use:

• Linux: vot-vxx-x86_64-unknown-linux-musl.tar.gz
• MacOS: vot-vxx-x86_64-apple-darwin.tar.gz
• Windows: vot-vxx-.zip

WARNING: for linux, use musl instead of gnu (high chances of uncompatibility in the latter case)

The tar contains a single executable binary file.

tar xzvf vot-vxx-yyy.tar.gz
./vot

Compile from source code

Install rust (and check that ~/.cargo/bin/ is in your path), or update the Rust compiler with:

rustup update

Clone the votable lib rust project:

git clone https://github.com/cds-astro/cds-votable-rust

Install from using cargo:

cargo install --path crates/cli
