twidge - Microblogging client for Twitter, Identica

SYNOPSIS

twidge [ -d ] [ -c FILE ] command [ command_args ]

twidge --help

DESCRIPTION

twidge is a client for microblogging sites such as Twitter <URL:http://twitter.com/> and
Identica <URL:http://identi.ca/> (identi.ca). Microblogging sites let you post short one-
paragraph updates, follow the updates that your friends post, and interact with everyone
in the site in a conversation style.

twidge is a client to make working with microblogging sites faster and easier. It is
extremely versatile, and can be customized to work the way you want to work, and combined
with other tools to do just about anything.

twidge can be used quite nicely interactively from the shell. It is useful directly as-
is, and with simple shell aliases can make a highly efficient system to do exactly what
you want. It is perfectly capable of being your only client for microblogging.

twidge also can be used in an automated way, via cron(1), or it can even integrate with
your email system.

A full list of twidge features, along with numerous suggestions on how to use it, can be
found at the twidge website at <URL:http://software.complete.org/twidge>.

But, if you'd like to get going RIGHT NOW, skip to the Quick Start section below. For
now, I'll summarize a few twidge features; a more comprehensive list is on the website.

FEATURE LIST
· Convenient, easy to learn, and fast command-line interface (it's simple to do simple
things, and advanced things are possible)

· This extensive manual, and numerous examples on the website

· Compatible with any microblogging service that implements the Twitter API. Tested with
Twitter and Identica (identi.ca). Should be compatible with any other system.

· Full support for reading the activity of your friends, replies to you, and your own
activity.

· Optional capability to remember what you have seen already and suppress those updates in
future runs.

· Optional automatic shortening of long URLs via is.gd

· Optional integration with your email system -- send and receive updates via email.

· Specifically designed to be friendly to use in shell scripts.

· Shell scripting makes it easy to do many things, such as scheduling future updates (with
at), ignoring certain updates (with grep), etc.

· Easy use of multiple accounts by having multiple configuration profiles. Mechanism
lends itself to shell aliases and tools.

· Small, minimalist footprint

· Output formats are easily parsed. Input formats are easily generated. Configuration
file format is liberal and easy to generate.

· Robust error detection and recovery throughout.

QUICK START

This section will describe how a first-time twidge user can get up and running quickly.
It assumes you already have twidge compiled or installed on your system. If not, please
follow the instructions in the INSTALL file in the source distribution.

To get started, simply run twidge setup at your shell prompt. twidge will lead you
through the first-time configuration -- which is very quick and completely self-
explanatory!

Now, let's start exploring. twidge lsrecent -su will show you the 20 most recent updates
from the people you follow. After the first time, it will remember what you've seen and
only show you new updates. In place of lsrecent, you could substitue lsreplies to replies
to you. You can also run twidge lsrecent --help, or refer to this document, for more
details on the command. In short, -s tells the system to save what you've seen, and -u
tells it to only show you unseen items.

You can subscribe to updates from friends by running twidge follow nick. To subscribe to
updates for twidge itself, you'd run twidge follow unixtwidge. If you've had enough of
updates from someone, just use the twidge unfollow command.

Now, how about posting your own updates? Just type twidge update. Type your update, and
press Enter when done. Your update may scroll past the end of the screen; don't worry
about it. Just don't hit Enter until you're done. You can also pass your update on the
command line, taking care to quote it if it contains spaces or shell characters.

That's the quick tour. For many more examples, refer to the website.

OPTIONS

twidge always is invoked with the name of a specific operation, such as update or
lsrecent. In twidge, these operations are called commands. Each command has its own
options, which are given after the command on the twidge command line. A full summary of
each command's options is given later in this manual.

You may obtain a list of all commands with twidge lscommands. Help is available for any
individual command with twidge command --help. Global help is available with twidge
--help.

GLOBAL OPTIONS
These options may be specified before any command.

-c FILE

--config=FILE
By default, twidge uses ~/.twidgerc for configuration. With this option, you can
specify an alternate file. twidge will read configuration information from it. In
certain cases, twidge will also write to it, such as with the twidge setup command,
or the -s option to one of the ls commands.

-d

--debug
Enables debugging output. This verbose output helps you learn what twidge is doing
every step of the way and diagnose any problems you may encounter.

COMMANDS IN TWIDGE

twidge has many different commands. You must specify a command when using twidge. This
section will discuss each command in detail. Note that all commands are case-sensitive
and should be given in lowercase.

All commands support the option --help. Running twidge command --help will display
information about the command and its options. Since all commands support this, it won't
be explicitly listed for each command below.

COMMANDS TO DISPLAY UPDATES

twidge ls* [ -a ] [ -l ] [ -s ] [ -u ]

Several commands can display updates from yourself or others. They all share a common
syntax and common set of options. The commands are lsdm, lsdmarchive, lsrecent,
lsreplies, and lsrtreplies. Here are the common options:

-a

--all Normally, microblogging sites return one "page" of results -- typically, 20 or 100
results, depending on the operation. Specifying --all requests twidge to
continually send requests to the microblogging site until it receives an entire set
of information. Normally this is a bad idea, but when used in combination with -u
-- especially if you have used -s before -- it can be a useful way to poll for all
new updates.

If not used carefully, this command can generate many requests to the server and
can use a significant amount of bandwidth. Microblogging sites have traffic
limits, and will not take kindly to this. Be careful when you use --all.

-e command

--exec=command
Causes any normal output to be suppressed. Instead, for each item that is
retrieved, call the given command. The command will be passed exactly four
arguments. Care should be exercised when using them in shell scripts due to the
likelihood of the presence of shell metacharacters. The arguments are:

1. The update ID for the given update.

2. The username that created the update

3. A suggested Message-ID for representing the update in email. Contains the
enclosing angle brackets.

4. The update text itself. Likely contains spaces and other shell metacharacters.

-l

--long The default output format shows a nickname and a message, formatted nicely for
display. Using this option causes output to include these columns: message ID,
sender nick, recipient nick (empty unless a direct message), update text, and date
created. The output format is suitable for machine parsing. horizontal tab
character \t separates the columns, and is guaranteed to appear nowhere else. It
is also guaranteed that \n will appear nowhere within a line when using -l.

The columns as presented are anticipated to remain stable. However, additional
columns could be added to the right of these columns in future versions of twidge.
Well-behaved parsers should be prepared to discard any surplus columns to the right
of those specified in this document.

-m address

--mailto=address
Causes any normal output to be suppressed. Instead, for each item that is
retrieved, generate an email and send it to the given address. The subject line
will contain the sender nickname and the first 30 characters of the text. The body
will contain the entire text. The message is sent by using the program listed as
sendmail in the configuration file. If mailfrom is listed in the configuration
file, it is listed as the from address and the name of the sender is listed as the
from comment.

A Message-ID designed to uniquely identify this update is generated and included.
In addition, headers beginning with X-Twidge- will be added, with various metadata.

It should be noted that a simple script could be used with --exec to achieve this
same purpose, but with greater flexibility. The functionality is built into twidge
as well for convenience.

-s

--saveid
Saves the ID of the most recent fetched message for future use with -u. Requires
write access to your configuration file.

-u

--unseen
Causes the command to show only items since the last use of -s with this particular
command. If -s has never before been used with this command, has no effect.

Some of these options don't make sense together; for instance, --long, --exec, and
--mailto are mutually exclusive. Results are undefined if you use such options
simultaneously.

LSDM
Lists direct messages sent to you. Note: identi.ca does not support direct messages, and
this will cause an error with that service.

LSDMARCHIVE
Lists direct messages you have sent. Note: identi.ca does not support direct messages,
and this command will cause an error with that service.

LSRECENT
Lists recent posts made by you or the people you follow.

LSREPLIES
Lists recent replies made by anyone on the microblogging site to you.

LSRTREPLIES
List retweets of your statuses made by others.

Note: identi.ca doesn't support new-style retweets and will return an error on this
command.

COMMANDS TO DISPLAY OTHER INFORMATION

These commands honor --all and --long like the other commands, but do not honor --saveid
or --unseen, as these options make no sense.

LSFOLLOWERS
twidge lsfollowers [ options ] [ username ]

Will slow a list of people following you. If given an optional username, shows the people
that follow that user. If given --long, shows the IDs for each person. You may need to
use --all to get a complete list, but again this may generate significant traffic.

LSFOLLOWING
twidge lsfollowing [ options ] [ username ]

Shows a list of the people you follow. Arguments and actions are the same as with
lsfollowers.

ACTION COMMANDS

These commands perform an action on the server.

DMSEND
twidge dmsend recipient [ status ]

Causes twidge to send a new direct message to the designated recipient. If a status is
given on the command line, it must be presented as a single argument to twidge by the use
of shell quoting if needed. If no status is given on the command line, a single line will
be read from stdin and used as the status.

The maximum length of updates on various microblogging sites is 140 characters. Twidge
will abort with an error if your update attempt exceeds that length.

By default, Twidge will attempt to shorten URLs in your updates via an URL shortening
service, but only if your update's length exceeds 140 characters. This means long URLs
shorter than 140 characters WILL NOT be shortened.

If you want all your URLs to be shortened all the time regardless of their length, then
set shortenall = yes in the [DEFAULT] or [dmsend] section of your configuration file.

You can disable URL shortening altogether by setting shortenurls = no in the [DEFAULT] or
[dmsend] section of your configuration file.

FOLLOW
twidge follow username

This command will cause twidge to request that the microblogging site add the given
username to the list of people you follow. It is considered an error to attempt to add
someone you already follow.

SETUP
twidge setup

Enters the interactive first-time setup tool.

UNFOLLOW
twidge unfollow username

This command will cause twidge to request that the microblogging site remove the given
username from the list of people you follow. It is considered an error to attempt to
remove someone you do not follow.

UPDATE
twidge update [ -i MSGID | --inreplyto MSGID ] [ status ]

twidge update -r

Causes twidge to post a new status to the server. If a status is given on the command
line, it must be presented as a single argument to twidge by the use of shell quoting if
needed. If no status is given on the command line, a single line will be read from stdin
and used as the status.

The maximum length of updates on various microblogging sites is 140 characters. Twidge
will abort with an error if your update attempt exceeds that length.

By default, Twidge will attempt to shorten URLs in your updates via an URL shortening
service, but only if your update's length exceeds 140 characters. This means long URLs
shorter than 140 characters WILL NOT be shortened.

If you want all your URLs to be shortened all the time regardless of their length, then
set shortenall = yes in the [DEFAULT] or [dmsend] section of your configuration file.

You can disable URL shortening altogether by setting shortenurls = no in the [DEFAULT] or
[dmsend] section of your configuration file.

When -r is given, twidge expects to read an RFC2822 email message in stdin. The body of
the message will be used as the content of the update. The References header of the
message will be briefly scanned, and if appropriate, the reply-to attribute of the update
will reflect the Message-ID referred to therein. This way, if you use twidge lsrecent
--mailto to email recent items to you, then use your email reply button to reply to them,
twidge will link the two on Twitter. This linkage can be done even if you omit @reply,
but will likely confuse many people because most other clients can't do this. You should
still include @reply.

It should be noted that, in an effort to minimize size and complexity, twidge has an
extremely simple email parser. You should send it only plain text messages. Do not use
HTML, RTF, attachments, or anything that would cause MIME headers to appear in the RFC2822
body. You probably want to turn off your signature as well. twidge will convert newline
characters to spaces when processing your message body.

When -i is given, the internal Twitter ID of a message is expected to be passed. This
sets the "in reply to" flag on Twitter appropriately.

OTHER COMMAND

LSCOMMANDS
twidge lscommands

This command will display a list of all available twidge commands along with a brief
description of each.

TWIDGE CONFIGURATION FILE

twidge has a configuration file in which you can set various options. This file normally
lives under ~/.twidgerc.

The configuration file has multiple sections. Each section has a name and is introduced
with the name in brackets. Each section has one or more options.

The section named DEFAULT is special in that it provides defaults that will be used
whenever an option can't be found under a different section. If you specify no section
names, DEFAULT is the assumed section. Some items, such as urlbase, are assumed to be in
DEFAULT.

Let's start by looking at an example file, and then proceed to examine all the options
that are available.

[DEFAULT]

; If your password contains a percent sign (%), list it twice (%%)

; Path to server API interface -- no trailing slash
urlbase = https://twitter.com

shortenurls = yes

; Last IDs seen by different commands. Written to with -s.

[lsrecent]
lastid = 914881241

Whenever twidge looks for information about a particular option, it first checks to see if
it can find that option in a section for that option. If not, it checks the DEFAULT
section. If it still doesn't find an answer, it consults its built-in defaults.

GENERAL OPTIONS
These are specified in the DEFAULT section.

serverbase
The base URL to access the API of the microblogging site. This should contain the
server name but not the API path. The default is https://api.twitter.com. For
Identica, you would use http://identi.ca/api (note that some users have trouble if
attempting to use SSL with identica)..

urlbase
The URL to access the API of the microblogging site. The default, %(serverbase)s/1
is for Twitter. To use Identica, you would specify %(serverbase)s. Do not put a
trailing slash on this option.

oauthrequesttoken
The URL to access the oAuth request token interface. The default,
%(serverbase)s/oauth/request_token, will work with most environments.

oauthaccesstoken
The oAuth access token URL. Default is %(serverbase)s/oauth/access_token.

oauthauthorize
The oAuth authorize URL. Default is %(serverbase)s/oauth/authorize.

oauthconsumerkey
The oAuth consumer key. Twidge is registered with Twitter and identi.ca and will
supply a reasonable default for those two based on the content of urlbase.

oauthconsumersecret
The oAuth consumer secret. A default is provided as with oauthconsumerkey.

oauthdata
Automatically written by twidge setup. Do not alter.

PER-COMMAND OPTIONS
These options may be specified in DEFAULT or in a per-option section. If placed in
DEFAULT, they will apply to all relevant options unless overridden.

lastid Stores the last ID seen for commands that support -s or -u.

mailfrom
Gives the email address to use for the From: header on messages generated by
twidge. Normally specified in [DEFAULT] so as to impact all commands. If not
given, twidge specifies no From: line, leaving the system's mail transport to
assign a default one.

Should contain a bare email address only -- no brackets, parens, quotes, or
comments.

When given, Twidge uses the nickname and this address for the From line. When not
given, the nickname is prepended to the Subject line.

savelast
For one of the "ls" class of commands, implies -s on every invocation, rather than
require it to be manually given. This option need only be present; the value you
give it doesn't mater.

sendmail
Stores the path to the sendmail executable on your system, used for sending mail.
Normally specified in [DEFAULT] so as to impact all commands. Defaults to
/usr/sbin/sendmail.

shortenurls
You may specify shortenurls in the [update] section. It defaults to yes. If set
to no, will cause twidge to omit its attempt to shorten URLs in your updates. If
set to yes, will cause twidge to shorten URLs in your updates, only if the latter's
length exceeds 140 characters. See shortenall

shortenall
You may specify shortenall in the [update] section. It defaults to no. If set to
yes, will cause twidge to shorten all URLs in your updates, all the time. It only
makes sense if shortenurls is set to yes.

URL SHORTENING OPTIONS
twidge uses is.gd as its default URL shortening service.

To enable the bit.ly or j.ump URL shorteners, you must add a [bitly] or [jmp] section to
the configuration file. This should contain two entries: login and apikey as found in
<URL:http://bit.ly/account/>. For example:

[jmp]
login: bitlyapidemo
apikey: R_0da49e0a9118ff35f52f629d2d71bf07

ALIASES
You can add an [alias] section to the config file which will effectively create new
commands. For example:

[alias]
recent: lsrecent -u
replies: lsreplies -u

TIPS & HINTS

Here are a few tips and hints to make twidge more pleasant for you.

GOING THROUGH A PROXY
If your connections must go through a proxy, you'll need to set an environment variable.
If you use an environment variable, your settings may will also impact other applications
-- and that's probably what you want. See the Environment section later for tips on doing
that.

ENVIRONMENT

twidge does not read any environment variables directly. However, it does pass on the
environment to the programs it calls, such as Curl. This can be useful for specifying
proxies. Please see curl(1) for more details.
