Sweeper - the Swiss Army Knife of recording management

Sweeper256.png

Overview

Sweeper is a Custom Firmware package for managing recordings in a variety of ways using custom rules. It started life as a simple utility for tidying up one-off recordings in the top level of the My Video area into folders, hence its name, but has since evolved into a multi-purpose tool.

Once installed, the rules that apply to the recordings and series folders at the top level of the My Video area can be accessed via the Sweeper icon on the main menu or toolbar. It is also possible to define rules for other folders by selecting Sweeper Rules from the OPT+ menu alongside the folder in the web interface.

User Interface

Sweeper Main.png

The main sweeper rule screen shows the rules which are currently defined for the folder followed by a set of buttons which can be used to add new rules, save or discard any changes, view or test the configuration and optionally show a textual representation of each rule, updated in real-time as changes are made.

At the bottom of the screen is an option to add a pre-defined ruleset to the rules already on screen. A set of rules can be chosen from the dropdown list and then added to the list of rules with a click on the Add to rules button; once there they can be individually modified, disabled or deleted as required.

All changes made are immediately reflected on screen but no changes are made to the system configuration until the Save changes button is pressed and confirmed.

Anatomy of a Rule

Each rule is shown in a box with an icon to the top left indicating whether it is a file or folder rule...

Tokens

Several of the rule actions take parameters, and these parameters can contain tokens that are replaced with information from the recording which is being processed. For example, you could use the Move recording to folder action with an argument of %genre which would place Films in a folder called Films, Children's recordings in one called Children, etc.

The available tokens are shown below:

 %orig The original version of the item being modified. For example to append _backup to the filename in a setfilename action, you would set the filename to %orig_backup.
 %title Recording title.
 %filename Recording filename.
 %basename The base name of the recording filename (without the directory and file extension).
 %folder Complete folder name (including /media/My Video or equivalent).
 %bfolder Base Folder name (without /media/My Video or equivalent).
 %synopsis Recording synopsis.
 %epname The name of the episode as extracted from the recording synopsis. Reliant on the broadcasters providing the data.
 %series The number of the series (extracted from the synopsis, 0 if not found).
 %episode The episode number (extracted from the synopsis, 0 if not found).
 %episodes The number of episodes in the series (extracted from the synopsis, 0 if not found).
 %epdescr A representation of the series and episode data found in the synopsis, e.g. s15e5/10. Unknown fields are replaced with a ?
 %channel Channel name.
 %lcn Logical channel number.
 %genre Recording genre.
 %definition Definition of recording (HD or SD).
 %duration Recording duration (in minutes).
 %timestamp Recording start time as YYYYMMDDHHMMSS.
 %yyyymmmdd Recording start time as YYYYMMDD.
 %hhmm Recording start time as HHMM.
 %hh Recording start hour as HH.
 %mm Recording start minute as MM.
 %year Recording start year as YYYY.
 %2digityear Recording start year as YY.
 %month Recording start month number 1-12.
 %2digitmonth Recording start month number 01-12.
 %date Recording start date 1-31.
 %2digitdate Recording start date 01-31.
 %shortday Recording start day (short form, e.g. Mon)
 %longday Recording start day (long form, e.g. Monday)
 %shortmonth Recording start month (short form, e.g. Jan)
 %longmonth Recording start month (long form, e.g. January)
 %etimestamp Recording end time as YYYYMMDDHHMMSS.
 %eyyyymmmdd Recording end time as YYYYMMDD.
 %ehhmm Recording end time as HHMM.
 %ehh Recording end hour as HH.
 %emm Recording end minute as MM.
 %replace:string:search:replace: Perform a substitution on string replacing search with replace. The delimiter (shown here as :) can be anything as long as the same character is used in all three places. Requires Sweeper version 2.1.1.
 %regsub:string:search:replace: As replace but supports regular expressions. Requires Sweeper version 2.1.1.
 %asfilename:string: Convert the argument to a filename as the Humax software would, replacing reserved characters with underscores.
 %asuniqfilename:string: As above but if the resulting filename already exists then append a number to the end to make it unique. Requires Sweeper version 2.1.1.
 %format:formatspec:string: Format a string using a Jim format specification.
Example: %format:%06d:%episode: returns the episode number padded with leading zeros to make it up to 6 characters.
Example: %format:08b:%episode: returns the episode number in binary.
 %%variablename Replace with the contents of the named variable (set previously with a set action).
 %replace:search:replace: Deprecated, use three argument version instead. Perform a substitution on the result replacing search with replace. The delimiter (shown here as :) can be anything as long as the same character is used in all three places.
 %regsub:search:replace: Deprecated, use three argument version instead. As replace but supports regular expressions.

In the configuration file, all conditions can be optionally prefixed with a ! to indicate negation. For example, the condition !lcn 1 means not recorded from channel 1.

String matching

When a condition takes a string argument for a match, that can either be a fixed string, a pattern or a regular expression. A fixed string is treated as a substring match - it is just looked for anywhere in the attribute. A regular expression is specified by prefixing it with a ~ character. A pattern is matched against the whole attribute and can contain the following special sequences:

*
Matches any sequence of characters in string, including a null string.
 ?
Matches any single character in string.
[chars]
Matches any character in the set given by chars. If a sequence of the form x-y appears in chars, then any character between x and y, inclusive, will match.
\x
Matches the single character x. This provides a way of avoiding the special interpretation of the characters \*?[] in pattern.
