# PrePostPrint political compass generator (`ppppcg`)
|
||||
|
||||
A [PrePostPrint](https://prepostprint.org) inspired political compass generator
|
||||
with SVG output.
|
||||
|
||||
## Install
|
||||
|
||||
> TODO
|
||||
|
||||
## Usage
|
||||
|
||||
Create a configuration file in your current working directory. `ppppcg.yml` is
|
||||
the default, you can use the `-c` flag to customise this. Here's an example
|
||||
inspired by `@mb`.
|
||||
|
||||
```yaml
|
||||
width: 500
|
||||
height: 500
|
||||
|
||||
axis:
|
||||
top: W3C
|
||||
right: Industry
|
||||
bottom: Custom hacks
|
||||
left: Punk
|
||||
|
||||
comments:
|
||||
left: Aesthetics
|
||||
bottom: Approach
|
||||
|
||||
points:
|
||||
- name: OSPKit
|
||||
x: 20
|
||||
y: 20
|
||||
```
|
||||
|
||||
Then run `ppppcg` in the same directory.
|
||||
|
||||
```
|
||||
ppppcg
|
||||
```
|
||||
|
||||
A SVG will be outputted. This can be piped to a graphical program such as `display`:
|
||||
|
||||
```
|
||||
pcg | display
|
||||
```
|
||||
|
||||
You can also save them to file and embed them in HTML pages:
|
||||
|
||||
```
|
||||
pcg > pcg.svg
|
||||
```
|
||||
|
||||
You can easily add a new point:
|
||||
|
||||
```yaml
|
||||
points:
|
||||
// ...
|
||||
- name: PagedJS
|
||||
x: 700
|
||||
y: 700
|
||||
```
|
||||
|
||||
Enjoy ✌️
