Webster is #openttdcoop's general use bot. He is based on supybot and as such has some strange quirks
This page is a quick 'cheat sheet' to the more useful stuff
Webster is triggered by the prefixes;
In IRC: @, (?: j: def: jargon: d: define:)
In game: @@cmd or @@(cmd arg1 arg2 etc)
<option> - These arguments are required
[<option>] - These arguments are optional

Users

Important Note: Any action involving a password must be done via a pm or query i.e. '/query Webster' or '/msg Webster <action>'

All commands listed are prefixed by user, this is not strictly required for all commands, as some only exist in the 'user' plugin.

Adding a new user

user register <name> <password>

Creates a new user on the bot, and links your current hostmask to it

Log in to your username

user identify <name> <password>

If your hostmask has changed, then you can log in by using this
(Hint: You can add " /msg Webster user identify <name> <password> " to your clients OnConnect (or similar))

whoami

Returns who the bot thinks you are

Manipulating hostmasks & log in settings

user hostmask add

Add your current hostmask. Obviously this only makes sense after identify.

user hostmask add [name] [hostmask] [password]

Add hostmask for another user. If not owner, password must be given.

hostmask list [<name>]

Returns the hostmasks of the user specified by <name>; if <name> isn't specified, returns the hostmasks of the user calling the command.

user hostmask remove <name> <hostmask> [password]

Removes the hostmask <hostmask> from the record of the user specified by <name>.
If the hostmask given is 'all' then all hostmasks will be removed.
The <password> may only be required if the user is not recognized by his hostmask.

user set secure <password> [<True|False>]

Sets the secure flag on the user of the person sending the message.
Requires that the person's hostmask be in the list of hostmasks for that user in addition to the password being correct.
When the secure flag is set, the user *must* identify before he can be recognized.

Changing password

user set password <user> <old password> <new password>

Renaming a user

user changename <name> <new name> [password]

Users can change their name themselves.

Curve Length Calculator

clcalc <railtype> [<tilt>] <number>

If <number> is under 30, this will return the max speed that a CL of <number> will produce. Otherwise, it will return the CL required for <number>km/h
Where <railtype> is either (e)rail, monorail or maglev, and [<tilt>] applies the tilt bonus.
Notes:
It should be noted that this command talks about both CL and half tiles. A CL if the value that the measurement tooltip shows, when dragging out a stretch of rail. A half tile, is another name for a diagonal (since they fit half the GRFs than a full one)
clcalc takes arguments in CL, but since OpenTTD counts each separate tile as one (see Max Curve Speed), "half tiles" are used for calculation, and shown for reference.

These commands have been replaced by the new clcalc, but are still available

<train/mono/mag>cl <speed km/h>
 use one of train/mono/mag e.g.
 traincl <speed>

Returns minimum CL for full <speed> transit (assuming TL > CL returned else use TL)

<train/mono/mag>clspd <cl>
 use one of train/mono/mag e.g.
 trainclspd <cl>

Returns the max-speed a <cl> can manage

Line split (tunnels) calculator

tunnels <trainlength> [<split>]

Returns minimum and maximum signal gap sizes for 2,3 and 4 linesplits with <trainlength>. If <spilt> is given it will return the the gap sizes for <split> (+/-) 1.
This uses the same formula that !tunnels uses. A 'gap' is usually either a) The average signal gap size or b) the largest single break in signals.
These values are NOT absolute, expected traffic density and some experience should also be applied.

This command is also aliased to:

gap gaps split splits tunnel and tunnels

This replaces the old and removed command:

tunnels <trainlength>

Gives you some gap threshold values for 2,3,4 tunnels at <trainlength>

One consequence is that large values such as '10**24' might not be exact.
