## Client API functions
You can use these functions on Lua pages.

 
`firewolf.version` - The Firewolf Browser's version as a string. Ex: `3.4`

`firewolf.domain` - The domain name of the site. Ex: `mysite.com`

`center(text)` - Center writes text.

`firewolf.redirect(url)` - Redirects the browser to another url, For example: `firewolf.redirect("mysite.com/page")` See [Server API - Queries](Server-API#queries) and `firewolf.encode(vars)` for advanced usage.

`firewolf.download(page)` - Downloads a file from the connected server to the /downloads folder on the client.
<br>Returns: _boolean_ success, _string_ file path/error message. See example below.

`firewolf.loadImage(page)` - Loads an image as returned by `paintutils.loadImage(path)` from the server.
<br>Returns: _image_ image, _string_ error message. See example below.

`firewolf.encode(vars)` - Encodes the dictionary table into the URL query format, the same way `firewolf.query(page, [vars])` does it. For custom redirect requests, or for other things. See [Server API - Queries](Server-API#queries) for more information. See example below.

`firewolf.query(page, [vars])` - Sends a request/query/data to the server and returns the text sent back from the server, recommended to be used in conjunction with the [Server API](Server-API) to make things like forms and logins. `vars` is a dictionary table to be sent along with the url request, See [Server API - Queries](Server-API#queries) for more information.
<br>Returns: _string_ string the server responded with, otherwise false if error. See example below.

## Examples
`firewolf.download(page):`

```lua
local success, msg = firewolf.download("myprogram")
-- This would be hosted on the server directory as 
-- /fw_servers/mysite.com/myprogram
if success then
    print("File downloaded to: " .. msg)
else
    print("Error while downloading file: " .. msg)
end
```
<br>

`firewolf.loadImage(page):`

```lua
local image, error = firewolf.loadImage("image")
if image then
    -- Draws the image in the top left corner
    paintutils.drawImage(image, 1, 1)
else
    print("Could not load image: " .. error)
end
```
<br>

`firewolf.encode(vars):`

Vars should be a dictionary table, like: `{["cat"] = "meow", ["dog"] = "woof"}`. All objects in the table should be strings, else they would be converted to strings. The [Server API](Server-API#queries) will be able to receive this dictionary table as a parameter to the handler function.

```lua
vars = {["cat"] = "meow", ["dog"] = "woof"}
local resp = firewolf.encode(vars)
print(resp) -- ?cat=meow&dog=woof
```
<br>

`firewolf.query(page, [vars]):`

See `firewolf.encode(vars)` for use of vars
```lua
vars = {["cat"] = "meow", ["dog"] = "woof"}
local resp = firewolf.query("query", vars)
if resp then
    print("Server responded with: " .. resp)
else
    print("Error when querying server!")
end
```
