Action Tracker Plugin

This plugin provides support for tracking actions embedded in meeting minutes. As you write the minutes during the meeting, you simply enter the actions into the text and as soon as the topic is saved, the actions "go live".

WARNING: TWiki-4 only. If you want to use this plugin with an earlier version of TWiki, please see here

Actions are nicely formatted for display, and automatic notification of actions is supported using 'cron'. The action tracker can also be used for private reminders, for example TODO lists and diary entries, and has been successfully applied to functions as diverse as risk management and bug tracking.

( Discussion in TWiki:Plugins/ActionTrackerPluginDev )

This version is the 'Dakar' release version. It will not work with versions of TWiki released before 2005. Older versions of the plugin are available from TWiki:Plugins/ActionTrackerPlugin

Features

• Actions may be embedded in TWiki topics.
• Actions can be listed using searches.
• A script is provided for automatic action notification.
• Actions can be assigned to individuals, or to predefined groups of individuals.
• Fully configurable.

Syntax Rules

Actions

Write the command %ACTION{ attributes }% anywhere in a TWiki topic. All the text following the final % up to the next end-of-line is taken as the action description. Standard attributes are

Name	Value	Description	Auto-completed
who	See People	The person or team responsible for completing the action.	current user
due	See Date Formats	The due date	today
state	open or closed	Set to open if the action is still open; set to closed if the action is closed. To extend the state set, see Non-standard attributes.	open
notify	See People	wikinames, or e-mail addresses, of people to notify when the action changes. See Notification for details on action notification.
creator	See People	Who created the action.	current user
created	See Date Formats	Date the action was created.	today
closer	See People	Who closed the action.	if (and only if) state="closed", current user
closed	See Date Formats	Date the action was closed, if ever.	if (and only if) state="closed", today
uid	6 digit number	Unique ID of the action. See UIDs.	calculated

For example,

%ACTION{ who="TWikiGuest" due="01 Jan 2020" state="open" notify="AttillaTheHun" }% An action for TWikiGuest

If the action description doesn't all fit on one line you can use shell-style here-document syntax to grab the next few lines. For example,

%ACTION{ who="LittleOysters" state="open" }% <<EOF
The time has come, the walrus said,
To speak of many things.
Of shoes, and ships, and sealing wax,
Of cabbages and kings.
EOF

The delimiter must be a sequence of alphanumeric characters, and the closing delimiter must be on a line of its own.

The fields with an entry in the 'Auto-completed' column are automatically filled in, if they are missing, whenever someone saves the topic containing the action. The default values are as indicated in the table. You can override this behaviour by providing values for any of these attributes when you type the action. Note: you are not recommended to provide a value for the uid (see UIDs) field!

Action searches

Write the command %ACTIONSEARCH{ attributes }% anywhere in a TWiki topic. Standard attributes are

Name	Value	Description
who	See People	Person responsible for closing the action.
notify	See People	Persons who want to be notified of a change
state	late, or any legal state value	Set to late to search for late actions; set to any any legal state value to search for actions in that state. See Settings for details on how to extend the state set.
within	a number of days	Search for actions that are within a number of days of their due date. Usually used in conjunction with other attributes, such as state="open". Works in both directions, so you can use this to search for actions which are going to fall due within a certain number of days, or a negative number for actions that fell due between a time in the past and now.
web	Perl regular expression	A regular expression that matches the names of all the webs to search. If this attribute is omitted, the default is to search only the current web. Searching many webs is much slower, especially in a large installation. Webs marked NOSEARCHALL will not be searched.
topic	Perl regular expression	A regular expression that matches the names of all the topics to search. If this attribute is omitted, the default is to search all the topics in the selected webs.
due	Absolute or relative date expression. See Date Formats	Due date for the action.
creator	See People	Who created the action.
created	Absolute or relative date expression. See Date Formats	Date the action was created.
closed	Absolute or relative date expression. See Date Formats	Date the action was closed, if ever.
closer	See People	Who closed the action.
uid	6 digit number	Unique ID of the action.
format	Presentation format	See Formatting tables
header	Presentation format	See Formatting tables
orient	Presentation format	See Formatting tables
sort	Comma-separated list of field names	Fields to sort the matched actions by. For example, sort="$who,$due" will sort by who first and then due. This field is optional; by default the table will be sorted by due date.

For example,

%ACTIONSEARCH{ who="me" state="late" }%
%ACTIONSEARCH{ who="me" open late }%
%ACTIONSEARCH{ who="TWikiGuest" state="open" within="7" }%
%ACTIONSEARCH{ web=".*" who="Genghis.Khan@mongol.empire.org" state="open" within="7" }%

When you are searching for fields containing dates (such as closed, created and due) you can prepend one of the conditions >, <, >= and <= to the date. For example, closed=">1-Jan-1999" will match all actions that have been closed at any time since 1-Jan-1999, and created=">= 1-Jan-2000" will match all actions created this century. You can also specify dates relative to the current date and time. See Date Formats for details of how to specify relative dates. For example,

%ACTIONSEARCH{ state="closed" closed="> 7 days ago"}%

will search for all actions closed in the last 7 days.

Date formats

Absolute date formats

Absolute dates are required in action specifications. Date formats must be as recognised by Time::ParseDate. The following absolute date formats are recognised. Dates containing spaces must be enclosed in double-quotes.

• Dow, dd Month yy
• Dow, dd Month yyyy
• Dow, dd Month
• dd Month yy
• dd Month yyyy
• Month day{st,nd,rd,th}, year
• Month dd yyyy
• yyyy/mm/dd
• yyyy/mm
• mm/dd/yy
• mm/dd/yyyy
• mm/yy
• yy/mm (only if year > 12)
• yy/mm/dd (only if year > 12 and day < 32)

You are strongly recommended never to use the 'mm/dd/yyyy or mm/dd/yyyy' formats, to avoid confusing users in Europe (like me). Note that due to limitations in the Time::Parsedate module, dates before 1970 will not work as expected.

Relative date formats

When you are searching for fields containing dates (such as closed, created and due) you can specify dates relative to the current date and time. For example:

Syntax	Example	Notes
Dow after next	Tuesday after next
Dow	Tuesday	last Tuesday
next Dow	next Thursday
tomorrow	tomorrow
today	today
yesterday	yesterday
last dow	last wednesday
last week	last week	7 days ago
now	now
now + count units	now + 2 years
now - count units	=now - 3 weeks
+ count units	+ 31 days
- count units	- 2 months
count units ago	10 days ago

People

People are identified to the action tracker using a wikiname (e.g. Main.WilliamWallace or simply WilliamWallace) or an e-mail address (e.g. a_einstein@pto.co.ch). The e-mail address is useful if you want to notify people who aren't registered in the wiki, but bear in mind that if they are outside your firewall, they'll get action notifications but the chances are they won't be able to edit pages and close actions. Very annoying!

E-mail addresses of people are found by the process described below.

You can also use the shorthand me for the currently logged-in user (this is TWikiGuest unless you have been prompted for a username and password). In actions, this will automatically be expanded when the topic is saved, and in searches it will match the currently logged in user.

Groups

You can assign an action to a group defined using a TWiki group topic (see TWikiDocumentation). Alternatively you can give a list of people as the value of the attribute. For example,

%ACTION{who=TWikiAdminGroup ...}%
%ACTION{who="KnutHaraldsen,MagnusMagnusson" ...}%

Note in general you should not use these mechanisms for assigning actions, because the actions so created are not specific. Actions should be assigned to one person only, so that it's clear who is responsible for them.

UIDs

For administrators only: Each action is assigned a Unique Identifier (UID) when it is created. This UID is a six-digit number, and is generated when the action is first saved by incrementing a number in a special file (data/atUidReg under the TWiki installation). If this file is accidentally deleted, or is not writable, then you will have problems and you may get duplicate UIDs. Normally this won't matter a hoot, as UIDs only have to be unique within a single topic, but if you are using UIDs for something else you will need to take care.

Notification

ActionTrackerPlugin comes with a notifier script, like the mailnotify script used for WebNotify (see MonitoringSiteActivity^? for more information on setting up mailnotify). This script allows you to:

• examine all the actions in all webs (except those specified NOSEARCHALL) and notify owners of the state of actions,
• find actions that have changed state, and notify people who have registered an interest in that action.

The frequency with which actions are notified depends on how you set up your cron (or equivalent) jobs on the server.

The actionnotify script interprets its parameters as a search expression of the same type as that used in %ACTIONSEARCH%. All actions which match that expression will be notified to their owners.

Note that the actionnotify script must be run from the bin directory. This is so it can pick up the TWiki path configuration file, setlib.cfg.

For example, you could set up the cron jobs as follows:

0 * * * * cd /home/twiki/bin && ../tools/actionnotify "state=\"late\""
0 8,16 * * * cd /home/twiki/bin && ../tools/actionnotify "state=\"open\" within=\"3\""
0 0 * * * cd /home/twiki/bin && ../tools/actionnotify "state=\"open\" within=\"7\"
0 0 * * 1 cd /home/twiki/bin && ../tools/actionnotify "state=\"open\" within=\"30\"

(If you don't know cron, the first 5 fields are minute, hour, day of month, month and day of week. * means 'every'). This crontab will notify actions according to the schedule:

1. Actions that are late will be notified every hour, on the hour
2. Actions that are still open within three days of their due date will be notified twice a day, at 8am and 4pm
3. Actions that are still open within seven days of their due date will be notified once a day, at midnight.
4. Actions that are still open within thirty days of their due date will be notified once a week, at midnight on monday.

A rather aggressive schedule!

Note: At Wind River they notify folks three times a week on Mon, Wed and Fri for open action items due within 8 days. Crontab entry for geeks:

0 0 * * 1,3,5 (cd .../bin; ../tools/actionnotify state=open within=8 'web=[CEIMPSW].*' > .../logs/actionnotify.txt 2>&1)

You can configure the fields which are scanned to detect state changes; see Settings.

Translating names to e-mail addresses

The wikiname of the user to be notified is translated to a mail address according to the following rules:

• If the user has a personal page, and that personal page contains a line or lines matching
  spaces * Email: email address
  or
  spaces * E-mail: email address
  Alternatively if the topic is a group definition (the name ends in 'Group') then the line
  spaces * Set GROUP =
  is used to determine the wikinames of the people in the group. These are resolved to email addresses recursively. If that fails,
• If they appear in any WebNotify in any web, in the form of a line that gives an email address, then that address is used.
• If this fails and the 'who' name is a valid e-mail address, for example person@domain.co.uk, then that name is used.

Note: If a name cannot be translated to an e-mail address using the mechanisms described above, a warning will be output to data/warning.txt..

The actionnotify script is also used to notify users who have registered an interest in being notified when an action changes. This function of the script is activated when you use the changedsince parameter. changedsince is used to specify the time period within which changed actions are interesting. Any action which has changed in the given period will be notified to all users who have registered an interest in that action using notify. The changedsince value is a relative date string, which uses the following formats

• yesterday
• last dow
• last week
• now - count units
• - count units
• count units ago

where units may be minutes, days, hours, weeks, months or even years. count is just an integer. dow is the name of a day of the week. For example:

changedsince="last monday"
changedsince="now - 3 days"
changedsince="- 36 hours"
changedsince="3 days ago"

Obviously you have to be careful to synchronise your changedsince expression with the activation of your cron job. The ideal is to specify the same delta as the gap between cron activations. For example,

0 0 * * * cd /home/twiki/bin && ../tools/actionnotify 'web="News" changedsince="yesterday"'

will notify registered users of action changes that occurred in the last 24 hours. Note the use of single quotes to prevent expansion in the shell.

Notes:

1. Not all action changes get notified, only changes to certain sensitive fields. You can change the set of fields that are sensitive to changes by setting the NOTIFYCHANGES parameter, as described in Settings, below.
2. Unlike all other search terms, changedsince works as an OR term rather than an AND term. If you use a compound expression like late,changedsince=yesterday, this will not give you all late actions that changed since yesterday. Instead, it will give you all late actions and all actions that changed since yesterday.
3. If you give the parameter DEBUG to the actionnotify script, it will print out the mails that would have been sent to STDOUT. This is useful for debugging, and may be useful if you have some other processing in mind (such as piping to an alternative mail program).
4. changedsince requires RCS, and will not work with RcsLite.

Customisation

To customize the edit screen create a directory in the template directory that matches the name of the web. Copy the action tracker templates into the new directory.

Formatting search tables

The header, format and orient parameters of %ACTIONSEARCH{}% support formatting of the action table using a similar syntax to that described in FormattedSearch. For example:

%ACTIONSEARCH{ web="Directors" state="open" format="|$who|$text|$edit|" header="|Director|Films||" orient="rows" }%

Name:	Expands To:
$who	Who is responsible for the action
$due	When the action is due
$state	Current state of the action (see also note below)
$notify	Who to notify when the action state changes
$closed	When the action was closed, and who closed it
$creator	Who created the action
$created	When the action was created
$edit	A link to the action editor for this action
$uid	Unique identifier for the action
$web	Name of the web containing the action
$topic	Topic name containing the action
$text	Formatted action text
$n or $n()	New line
$nop or $nop()	Is a "no operation". This variable gets removed.
$quot	Double quote (").
$percnt	Percent sign (%)
$dollar	Dollar sign ($)

A default format for actions and action search results can be defined in this topic or the WebPreferences topic of the current web. See Settings for more details.

Non-standard Attributes

As well as the standard attributes you can add non-standard attributes to actions, and use them in searches. For example:

%ACTION{ who="EmperorHadrian" due="1 Jan 0053" state="closed" legion="7th" cohort="6th" maniple="3rd" }% Build a wall to keep the Scots out of England

Non-standard attributes must be lower-case words. The following names may not be used for non-standard attributes: closed, closer, created, creator, dollar, due, edit, format, header, late, n, nop, notify, percnt, quot, sort, state, text, topic, uid, web, who, within.

To define non-standard attributes you need to set the value of EXTRAS in this topic (or to the WebPreferences topic of each web) - see Settings below. All attributes must be given a type, which is used by the formatter, the search engine and the action editor. For example,

	* %Set EXTRAS = |plaintiffs,names,16|decision,text,16|sentencing,date|sentence,select,"life","5 years","community service"|

The following types are supported:

Type	Format	Description
select	select, size, "option 1", "option 2", ...	Can take one of the string values option1, option2,.... etc.
names	names, size	One or more wikinames or e-mail addresses.
text	text, size	An arbitrary text field
date	date, size	A date in one of the formats described above. See Date Formats

In the above, size is a single number, which is the width (in characters) of the text box in the action editor for text, names and date, and the number of options to show in select..

Note that there is one exception to the "no redefinition" rule above; the state attribute can be extended to take extra states. However if you want the closure functionality (closed, closer, and late actions) to work, the closed state must be retained. To extend the set of states, simply include a definition of state in the EXTRAS definition:

	* %Set EXTRAS = |state,select,1,"open","fried","boiled","poached","closed"|

Searching for non-standard attributes

You can of course search for values of non-standard attributes. For example:

%ACTIONSEARCH{ sentence="life" }%

If a non-standard attribute is declared as type text you can use perl regular expressions in the search. Searches for values of type names will match any-to-any. For example,

%ACTIONSEARCH{ car="VolkswagenBeetle,MercedesCoupe" }%

will match both of the following actions:

%ACTION{ car="VolkswagenBeetle,AudiSport" ... }%
%ACTION{ car="ToyotaSupra,MercedesCoupe,ColtLancer" ... }%

ActionTrackerPlugin Settings

These settings can be overridden in the WebPreferences topic of the current web (by defining ACTIONTRACKERPLUGIN_TABLEHEADER or ACTIONTRACKERPLUGIN_TABLEFORMAT etc).

• Set to 1 to enable debug features, including the undocumented %ACTIONNOTIFICATIONS{}% and %ACTIONTRACKERPREFS% features.
  • Set DEBUG = 0

• One line description, shown in the TextFormattingRules topic
  • Set SHORTDESCRIPTION = Adds support for action tags in topics, and automatic notification of action statii

• The format of an action output. The following fields can be output: web, topic, text, who, due, notify, uid, creator, state, edit, and any EXTRAS you may have. These settings can be overridden in an ACTIONSEARCH command using the format and header attributes. TABLEHEADER defines the column headings, TABLEFORMAT defines the contents of the columns, and if TABLEORIENT is set to "rows", action tables will be aligned as rows of values instead of the default columns of values.
  • Set TABLEHEADER = | Assigned to | Due date | Description | State | Notify ||
  • Set TABLEFORMAT = | $who | $due | $text | $state | $notify | $edit |
  • Set TABLEORIENT = cols

• The alternative text format of an action, as seen by a mail recipient who doesn't accept HTML in mail. Used when mailing action or change notifications.
  • Set TEXTFORMAT = Action for $who, due $due, $state$n$text$n

• Important changes since the last release: Colours are now defined in the stylesheet attached to this topic. The following settings are ignored:
  • #Set LATECOL = yellow
  • #Set BADDATECOL = red
  • #Set HEADERCOL = orange
• Full URL of the CSS to use in formatting actions.
• Set CSS = /pub/TWiki/ActionTrackerPlugin/styles.css

• The format of the fields in the action editor. You can also set EDITBOXWIDTH and EDITBOXHEIGHT to override the defaults (which are 70x15) just for the action editor.
  • Set EDITHEADER = | Assigned to | Due date | State | Notify |
  • Set EDITFORMAT = | $who | $due | $state | $notify |
  • Set EDITORIENT = cols

• If set to 1 will edit an action in a separate browser window (requires JavaScript)
  • Set USENEWWINDOW = 0

• If set to 1, action edits will offer a 'Save Changes' instead of the usual 'Preview Changes' button. If this is set along with the USENEWWINDOW parameter, the subwindow should close on save, but it won't because I haven't worked out how to do this safely in JavaScript.
  • Set NOPREVIEW = 1

• The fields to scan to detect changes for actionnotify. Changes in other fields are ignored.
  • Set NOTIFYCHANGES = $due,$state,$text

• Non-standard attributes - see Non-standard attributes above.
  • Set EXTRAS =

• Setup for Mishoo JSCalendar
• The following styles are available: system blue blue2 brown green tas win2k-1 win2k-2 win2k-cold-1 win2k-cold-2
  • Set CAL_STYLE = system
• The following languages are available: af es ko-utf8 ru br fi lt si ca fr lt-utf8 sk cs-win hr nl sp da hr-utf8 no sv de hu pl tr du it pl-utf8 zh el jp pt en ko ro
  • Set CAL_LANG = en
