DOStodon

This is the source of DOStodon, a Mastodon client for MS-DOS.

DOStodon is implemented in Javascript and relies on a yet unreleased version of DOjS to run.

Help on this project is very much appreciated, contact me on Mastodon or in the DOjS Discord if you want to help or have questions...

Quick start

  • You need a VM, real HW or DOSBox-staging with a network card and a matching packet driver to use it.
  • A Pentium 133 or faster with at least 32MiB of RAM is recommended.
  • Packet drivers can e.g. be found on packetdriversdos.net (make sure to download the driver from the "PC/TCP PACKET DRIVERS" section) or on crynwr.com or www.georgpotthast.de
  • You don't need any TCP/IP stack, Watt32 is compiled into the program and directly uses the packet driver
  • Make sure you read the section about the limitations!
  • see "DOSBox-staging config" below for an example config that works (for me) with DOSBox-staging

Just download the whole repository.

Attention:

Starting with 4.4.x Mastodon seems to have deactivated the "password" oAuth method. The only way to authenticate now (and get a valid token) seems to be via redirection to an HTML page that does the authentication (see here). Naturally DOStodon can not support that. Until there is a solution you will not be able to log into instances that do not support "password" authentication.

Linux version

There is a highly experimental Linux version of DOStodon included. It is based on DOjS v1.12. You can try it at your own risk. You need to compile DOjS yourself, please look at this instruction how to do that. Fullscreen mode does not get keyboard input on WSL2, you can switch to windowed mode by removing the -u option in dostodon.sh.

Usage

First start

Please run DOStodon <server> <email> <password>

  • server: the URL of the server you want to connect to (e.g. mastodon.social or https://bitbang.social). Can be with or without https:// prefix.
  • email: the email address used for registration (shown on the Preferences -> Account page in the web).
  • password: Your server password. 2FA is not supported. Your password should not contain any non 7bit ASCII characters.

Example: DOStodon mastodon.social jon@somwhere.com 123abcABC

The access tokens are stored in CREDS.JSN if the login is successful.

subsequent starts

Just run DOStodon.

Proxy support

If you want DOStodon to use a proxy you have to set the following ENV variables:

  • PROXY_HOST: HTTP proxy to use. The parameter should be a string holding the host name or dotted IP address. To specify port number in this string, append :[port] to the end of the host name. The proxy string may be prefixed with [protocol]:// since any such prefix will be ignored. The proxy's port number may optionally be specified with the separate function SetProxyPort().
  • PROXY_PORT: Pass a port number with this option to set the proxy port to connect to unless it is specified in the proxy string using PROXY_HOST.
  • PROXY_TYPE: set this to SOCKS to use a SOCKS proxy. If unset or set to anything else a HTTP proxy is asumed.

NOISE.SYS

DOStodon supports NOISE.SYS, a MS-DOS random number generator. It can be obtained here: https://github.com/robrwo/noise.sys

  • To add a content warning/spoiler to a toot start the toot with "cw:". The first line of the toot will be the content warning, all subsequent lines will be the body text of the toot.
  • If you press DOWN on the last entry in home/notifications older entries are fetched.
  • Favourite/boost/bookmark status ([FBM]) is displayed below the profile picture of each toot.
  • The selected hashtag is displayed in the upper right corner of the hashtag timeline.
  • When first selecting the hashtag timeline you have to enter a hashtag.

Limitations

  • 2FA is not supported right now!
  • logging in with passwords that contain characters outside 7bit ASCII might not be possible
  • HTTPS requests can take quite a lot of time, be patient!
  • Can't play videos/audio
  • Image attachements are just drawn at the upper left corner
  • No support for HTML tags, they are (badly) filtered out
  • No support for emojis (replaced by spaces)
  • No support for characters like umlauts, etc.
  • The toot composer only supports BACKSPACE, it is not a real text editor.
  • You can only remove the whole editor content. You can't undo adding an image.
  • You can only add ALT text for the last image added.
  • Bookmarks and favourites do not support pagination (yet).
  • NO REAL TESTING/QUALITY ASSURANCE! Folks, this is a fun project, if you need a production ready client contribute or use something real! If it works for you, it works, but don't blame me for broken commits or missing features...

Hacking/contributions

The source is split into several files right now:

  • dstdn.js the "application"
  • home.js the home timeline
  • imgcache.js image fetching/caching
  • info.js info screen display
  • splash.js splash screen
  • mstdn.js contains the Mastodon REST API
  • notific.js the notification timeline
  • profile.js profile viewer
  • toot.js toot creation
  • util.js support code
  • dialogs.js all input fields
  • filsel.js image file selector

DOStodon is implemented using DOjS native API (no p5js emulation). Network operations block the input processing/rendering.

DOSBox-staging config

I use DOSBox Staging to test this version of DOStodon. A NE2000 packet driver can be found on this page here.

DO NOT use DOSBox-X right now, it has a known bug in file io which creates broken SQLite databases DOSBox-staging has a problem with mouse support, thats why I disabled that in the example config!

My dosbox-staging.conf looks like this:

[sdl]
capture_mouse = nomouse

[dosbox]
memsize = 64

[cpu]
cputype = pentium_slow
cycles  = max

[ethernet]
ne2000  = true
nicbase = 300
nicirq  = 3
macaddr = AC:DE:48:88:99:AA

[autoexec]
mount c E:\_DEVEL\GitHub\DOStodon
PATH=d:;%PATH%
c:
ne2000 0x60 3 0x300

TODO

  • Busy indicator is missing for some network operations
  • Some network errors lead to an endless loop
  • Color themes?
  • invert timeline (oldest post on top)
  • Fix bugs
  • Have fun
