writeas-cli
===========
Command line interface for [Write.as](https://write.as) and [Write.as on Tor](http://writeas7pm7rcdqg.onion/). Works on Windows, OS X, and Linux.
Like the [Android app](https://play.google.com/store/apps/details?id=com.abunchtell.writeas), the command line client keeps track of the posts you make, so future editing / deleting is easier than [doing it with cURL](http://cmd.write.as/). The goal is for this to serve as the backend for any future GUI app we build for the desktop.
It is currently **alpha**, so a) functionality is basic and b) everything is subject to change — i.e., watch the [changelog](https://write.as/changelog-cli.html).
## Usage
```
writeas [global options] command [command options] [arguments...]
COMMANDS:
post Alias for default action: create post from stdin
+ new Compose a new post from the command-line and publish
delete Delete a post
update Update (overwrite) a post
get Read a raw post
- add Add a post locally
+ add Add an existing post locally
list List local posts
help, h Shows a list of commands or help for one command
GLOBAL OPTIONS:
--tor, -t Perform action on Tor hidden service
--tor-port "9150" Use a different port to connect to Tor
--help, -h show help
--version, -v print the version
```
