Note: This module is deprecated since version 0.11.3. You should use the async version of this module asyncftpclient.
This module partially implements an FTP client as specified by RFC 959.
This module provides both a synchronous and asynchronous implementation. The asynchronous implementation requires you to use the asyncFTPClient function. You are then required to register the AsyncFTPClient with a asyncio dispatcher using the register function. Take a look at the asyncio module documentation for more information.
Note: The asynchronous implementation is only asynchronous for long file transfers, calls to functions which use the command socket will block.
Here is some example usage of this module:
var ftp = ftpClient("example.org", user = "user", pass = "pass") ftp.connect() ftp.retrFile("file.ext", "file.ext")
Warning: The API of this module is unstable, and therefore is subject to change.

Procs
proc ftpClient(address: string; port = Port(21); user, pass = ""): FtpClient {.
raises: [OSError], tags: [].}- Create a FtpClient object. Source Edit
proc send[T](ftp: FtpBase[T]; m: string): TaintedString
-
Send a message to the server, and wait for a primary reply. \c\L is added for you.
Note: The server may return multiple lines of coded replies.
Source Edit proc connect[T](ftp: FtpBase[T])
- Connect to the FTP server specified by ftp. Source Edit
proc pwd[T](ftp: FtpBase[T]): string
- Returns the current working directory. Source Edit
proc cd[T](ftp: FtpBase[T]; dir: string)
- Changes the current directory on the remote FTP server to dir. Source Edit
proc cdup[T](ftp: FtpBase[T])
- Changes the current directory to the parent of the current directory. Source Edit
proc listDirs[T](ftp: FtpBase[T]; dir: string = ""; async = false): seq[string]
- Returns a list of filenames in the given directory. If dir is "", the current directory is used. If async is true, this function will return immediately and it will be your job to use asyncio's poll to progress this operation. Source Edit
proc fileExists(ftp: FtpClient; file: string): bool {.
deprecated, raises: [FTPError, Exception, OSError, ValueError, TimeoutError, ReplyError, OverflowError], tags: [RootEffect, WriteIOEffect, ReadIOEffect, TimeEffect].}-
Deprecated since version 0.9.0: Please use existsFile.
Determines whether file exists.
Warning: This function may block. Especially on directories with many files, because a full list of file names must be retrieved.
Source Edit proc existsFile(ftp: FtpClient; file: string): bool {.
raises: [FTPError, Exception, OSError, ValueError, TimeoutError, ReplyError, OverflowError], tags: [RootEffect, WriteIOEffect, ReadIOEffect, TimeEffect].}-
Determines whether file exists.
Warning: This function may block. Especially on directories with many files, because a full list of file names must be retrieved.
Source Edit proc createDir[T](ftp: FtpBase[T]; dir: string; recursive: bool = false)
- Creates a directory dir. If recursive is true, the topmost subdirectory of dir will be created first, following the secondmost... etc. this allows you to give a full path as the dir without worrying about subdirectories not existing. Source Edit
proc chmod[T](ftp: FtpBase[T]; path: string; permissions: set[FilePermission])
- Changes permission of path to permissions. Source Edit
proc list[T](ftp: FtpBase[T]; dir: string = ""; async = false): string
- Lists all files in dir. If dir is "", uses the current working directory. If async is true, this function will return immediately and it will be your job to call asyncio's poll to progress this operation. Source Edit
proc retrText[T](ftp: FtpBase[T]; file: string; async = false): string
- Retrieves file. File must be ASCII text. If async is true, this function will return immediately and it will be your job to call asyncio's poll to progress this operation. Source Edit
proc retrFile[T](ftp: FtpBase[T]; file, dest: string; async = false)
- Downloads file and saves it to dest. Usage of this function asynchronously is recommended to view the progress of the download. The EvRetr event is passed to the specified handleEvent function when the download is finished, and the filename field will be equal to file. Source Edit
proc store[T](ftp: FtpBase[T]; file, dest: string; async = false)
- Uploads file to dest on the remote FTP server. Usage of this function asynchronously is recommended to view the progress of the download. The EvStore event is passed to the specified handleEvent function when the upload is finished, and the filename field will be equal to file. Source Edit
proc close[T](ftp: FtpBase[T])
- Terminates the connection to the server. Source Edit
proc asyncFTPClient(address: string; port = Port(21); user, pass = ""; handleEvent: proc ( ftp: AsyncFtpClient; ev: FTPEvent) {.
closure, gcsafe.} = ( proc (ftp: AsyncFtpClient; ev: FTPEvent) = discard )): AsyncFtpClient {.raises: [OSError], tags: [].}-
Create a AsyncFTPClient object.
Use this if you want to use asyncio's dispatcher.
Source Edit proc register(d: Dispatcher; ftp: AsyncFtpClient): Delegate {.
discardable, raises: [], tags: [].}- Registers ftp with dispatcher d. Source Edit
