nonos is a 2D visualization command line application for planet-disk hydro simulations, as well as a Python library.
It works seamlessly with vtu-formatted data from Pluto, Fargo3D and Idefix.

:construction: This project and documentation are under construction :construction:
## Ongoing progress

* spherical coordinates
* error: `streamlines` & `rz=True` -> not yet implemented
* warning: `isPlanet=False` & `corotate=True` -> we don't rotate the grid if there is no planet for now. `omegagrid` = 0.
* warning: `geometry="polar"` & `rz=True` -> plot not optimized for now in the (R,z) plane in polar.


## Installation

:warning: Nonos requires Python 3.8 or newer. The easiest installation method is

```bash
$ pip install nonos
```

## Usage
### 1. On the command line

The nonos CLI gets its parameters from three sources:
- command line parameters
- a configuration file
- default values

Command line parameters take priority over the configuration file, which itself takes priority over default values.

To get help, run
```shell
$ nonos --help
```
```
usage: nonos [-h] [-dir DATADIR] [-field {RHO,VX1,VX2,VX3,BX1,BX2,BX3,PRS}] [-plane {rphi,rz,rtheta,xy,xz,yz}] [-range RANGE [RANGE ...]] [-vmin VMIN] [-vmax VMAX]
             [-cpu NCPU] [-on ON [ON ...] | -all] [-diff] [-log] [-isp] [-corotate] [-grid] [-slice] [-pbar] [-lic {V,B}] [-licres LICRES] [-dim {1,2}] [-scaling SCALING]
             [-cmap CMAP] [-fmt FORMAT] [-dpi DPI] [-input INPUT | -isolated] [-d | -version | -logo | -config] [-v]

Analysis tool for idefix/pluto/fargo3d simulations (in polar coordinates).

optional arguments:
  -h, --help            show this help message and exit
  -dir DATADIR          location of output files and param files (default: '.').
  -field {RHO,VX1,VX2,VX3,BX1,BX2,BX3,PRS}
                        name of field to plot (default: 'RHO').
  -plane {rphi,rz,rtheta,xy,xz,yz}
                        name of plane of projection (default: 'xy').
  -range RANGE [RANGE ...]
                        range of matplotlib window (default: unset), example: x x -2 2
  -vmin VMIN            min value in -diff mode (default: unset)
  -vmax VMAX            max value in -diff mode (default: unset)
  -cpu NCPU, -ncpu NCPU
                        number of parallel processes (default: 1).
  -on ON [ON ...]       output number(s) (on) to plot. This can be a single value or a range (start, end, [step]) where both ends are inclusive. (default: last output
                        available).
  -all                  save an image for every available snapshot (this will force show=False).
  -dim {1,2}            dimensionality in projection: 1 for a line plot, 2 (default) for a map.
  -scaling SCALING      scale the overall sizes of features in the graph (fonts, linewidth...) (default: 1).
  -cmap CMAP            choice of colormap for the -dim 2 maps (default: 'RdYlBu_r').
  -fmt FORMAT, -format FORMAT
                        select output image file format (default: unset)
  -dpi DPI              image file resolution (default: DEFAULTS['dpi'])

boolean flags:
  -diff                 plot the relative perturbation of the field f, i.e. (f-f0)/f0.
  -log                  plot the log10 of the field f, i.e. log(f).
  -isp                  is there a planet in the grid ?
  -corotate             does the grid corotate? Works in pair with -isp.
  -grid                 show the computational grid.
  -slice                perform a slice along the third dimension.
  -pbar                 display a progress bar

streamlines options:
  -lic {V,B}            which vector field for lic streamlines (default: 'unset')
  -licres LICRES        lic interpolation cell refinement (default: 5)

CLI-only options:
  -input INPUT, -i INPUT
                        specify a configuration file.
  -isolated             ignore any existing 'nonos.toml' file.
  -d, -display          open a graphic window with the plot (only works with a single image)
  -version, --version   show raw version number and exit
  -logo                 show Nonos logo with version number, and exit.
  -config               show configuration and exit.
  -v, -verbose, --verbose
                        increase output verbosity (-v: info, -vv: debug).
```

#### Using a configuration file

The CLI will read parameters from a local file named `nonos.toml` if it exists,
or any other name specified using the `-i/-input` parameter.
To ignore any existing `nonos.toml` file, use the `-isolated` flag.

One way to configure nonos is to use
```shell
$ nonos -config
```

which prints the current configuration to stdout.
You can then redirect it to get a working configuration file as
```shell
$ nonos -config > nonos.toml
```
This method can also be used to store a complete configuration file from command line arguments:
```shell
$ nonos -ncpu 8 -cmap viridis -rz -diff -vmin=-10 -vmax=+100 -config
```
As of Nonos 0.2.0, this will print
```
