# Clamxir [](https://travis-ci.org/ramortegui/clamxir)
ClamAV wrapper for elixir based on
[clamby](https://github.com/kobaltz/clamby)
This package depends of clamav installed on your system. Please refer to: [https://www.clamav.net/documents/installing-clamav](https://www.clamav.net/documents/installing-clamav).
As recomendation, use the daemonize flag on the configs, in order to improve
performance.
## Installation
The package can be installed by adding `clamxir` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:clamxir, "~> 0.1.8"}
]
end
```
## Usage
Clamxir receive the configs on each public method, and based on the configs,
will perform their task.
The config file by default is the struct `%Clamxir{}`. The default values of
the structure are:
```elixir
%Clamxir{
daemonize: false,
stream: false,
check: fase
}
```
daemonize is a flag to use one instance of the clamav instead of
the creation of new instances for each request.
```elixir
iex> Clamxir.safe?(%Clamxir{}, "/path/file")
```
stream will pass the argument --stream to clamdscan, this will help
to avoid permission issues.
```elixir
iex> Clamxir.safe?(%Clamxir{stream: true}, "/path/file")
```
check flag will add validation of the scanner availability before try
to run it.
```elixir
iex> Clamxir.safe?(%Clamxir{check: true}, "/path/file")
```
## Integration with Phoenix
1. Install as dependency
mix.exs
```elixir
{:clamxir, "~> 0.1.8"}
```
2. Use in the controller action where the files are uploaded
```elixir
def upload(conn, params) do
file = params["index"]["file"]
# Requires to have clamavdscann to work
case Clamxir.safe?(%Clamxir{daemonize: true}, file.path) do
true ->
# Process the file and ...
conn
|> put_flash(:info, "Created successfully")
|> redirect(to: "/")
false -> conn
|> put_flash(:error, "Virus!!")
|> redirect(to: "/")
end
end
```
