ClamAV API for Elm

An Elm library that provides access to the ClamAV virus scanning API.

This library is built on top of the node ClamAV library, clamav.js, which uses ClamAV to provide its virus scanning functionality.

Install

Elm

Since the Elm Package Manager doesn't allow for Native code and this uses Native code, you have to install it directly from GitHub, e.g. via elm-github-install or some equivalent mechanism.

ClamAV package

ClamAV daemon must be installed at the clamavHost and clamavPort (see ClamAV Config below).

Node modules

You'll also need to install the dependent node modules at the root of your Application Directory. See the example package.json for a list of the dependencies.

The installation can be done via npm install command.

Test program

Purpose is to test the clamav.js virus scanning API that this library supports . Use aBuild.sh or build.sh to build it and run it with node main.js command (see main.js for command line parameters).

API

ClamAV Config used in all virus scanning commands

Config

type alias Config =
    { clamavHost : String
    , clamavPort : Int
    , debug : Bool
    }

• clamavHost is the host name where the ClamAV daemon is running.
• clamavPort is the port where the ClamAV daemon is running.
• debug is True if debug logging is desired, False otherwise

Usage

config : Config
config =
    { clamavHost = "clamavHost"
    , clamavPort = 3310
    , debug = False
    }

Commands

Scan File for virus

Scan file for a virus using the ClamAV daemon.

scanFile : Config -> String -> ScannerCompleteTagger msg -> Cmd msg
scanFile config filename tagger =

Usage

scanFile config filename ScannerComplete

• ScannerComplete is your application's message to handle the different result scenarios
• config has fields used to configure the request
• filename is the name of the file to scan for a virus

Scan Buffer for virus

Scan a Buffer for a virus using the ClamAV daemon. This command uses Buffer defined in elm-node/core.

scanBuffer : Config -> String -> Buffer -> ScannerCompleteTagger msg -> Cmd msg
scanBuffer config targetName targetBuffer tagger =

Usage

scanBuffer config targetName targetBuffer ScannerComplete

• ScannerComplete is your application's message to handle the different result scenarios
• config has fields used to configure the request
• targetName is the name used to identify this scan in the ScannerComplete msg
• targetBuffer is the buffer to scan for a virus

Scan String for virus

Scan a String for a virus using the ClamAV daemon. This command uses Encoding defined in elm-node/core.

scanString : Config -> String -> String -> Encoding -> ScannerCompleteTagger msg -> Cmd msg
scanString config targetName targetString encoding tagger =

Usage

scanString config targetName targetString encoding ScannerComplete =

• ScannerComplete is your application's message to handle the different result scenarios
• config has fields used to configure the request
• targetName is the name used to identify this scan in the ScannerComplete msg
• targetString is the string to scan for a virus
• encoding is the encoding of the targetString (see Encoding defined in elm-node/core)

Subscriptions

There are no subscriptions.

Types

Name

Scan Name. This is filename for the ScanFile operation, and targetName for ScanBuffer and ScanString operations.

type alias Name =
    String

Error

Error information from a scan.

type alias Error =
    { message : String
    , virusName : Maybe String
    }

• message is the error message returned from the scan
• virusName the name of the virus if a virus was found during the scan, otherwise Nothing

ScannerCompleteTagger

Returns an Elm Result indicating a successful call to one of the Scan operations or an error consisting of (Name, Error).

type alias ScannerComplete msg =
    Result ( Name, Error ) Name -> msg

Usage

ScannerComplete (Ok name) ->
    let
        l =
            Debug.log "ScannerComplete" name
    in
    model ! []

ScannerComplete (Err (name, error)) ->
    let
        l =
            Debug.log "ScannerComplete Error" (name, error)
    in
        model ! []
