//
// Common functions for managing pages consisting of lists of several entries

// Some functions are specific for checking if entries belong to one or more
// lists.
// For instance: save personal notes on YouTube videos and highlight those that
// have been started but not finished, add buttons to twitter feeds, highlight
// Netflix movies based on IMDb lists, etc.

// To-do (priority: [H]igh, [M]edium, [L]ow):
// - [M] changes to a list aren't reflected in page till reload. Change?
// - [M] List regeneration method doesn't handle case where lists are missing

/* How to use this library
This library instantiates an EL object that must be initialized with a
"context" object that implements some variables and callback methods (see
below) specifically for the website to be processed (the target site).
Additional contexts can be passed, each related to a source of information to
be used in processing.
Call, in order:
0. EL.newContext(name) to initialize each source and target context, before
adding methods and variables
1. EL.init(ctx, loadlistsAtStartup), passing the target context object
-> not needed if you don't have external sources, just call EL.startup
- loadlistsAtStartup (default: false) tells whether lists should be loaded
from local storage during startup operations
2. EL.addSource(ctx) for each external source, with its specific context object
3. EL.startup(ctx, loadlistsAtStartup), skip arguments if EL.init was called.
Other methods and variables:
- addToggleEventOnClick(button, howToFindEntry[, toggleList[, toggleType]]):
mainly used in ctx.modifyEntry(), add an event listener that implements
a toggle action:
- button: the DOM object to attach the event listener to
- howToFindEntry: how to go from evt.target to the entry object. It can be:
- a number: # of node.parentNode to hop to get from evt.target to to entry
- a CSS selector: used with evt.target.closest to get to entry
- toggleList: the list where the entry is toggled when the button is pressed
(can be omitted if a default list is to be used)
- toggleType: the processing type that is toggled by the press of the button
(can be omitted if only one processing type is used)
It cannot be a falsy value (because it would mean no toggle)
- markInvalid(entry):
mark entry as invalid to skips it in subsequent passes
This method returns false so it can be used in isValidEntry() in this way:
return condition || EL.markInvalid(entry)
This leaves the return value unchanged and marks the entry only if invalid
- ln(listName, ctx): return list name as passed to determineType() (see below).
Default for "ctx" is target context.
- saveList(list, name, ctx): save list of entries to storage.
Default for "ctx" is target context.
- deleteList(name, ctx): remove a list from storage (but not from memory).
Default for "ctx" is target context.
- deleteAllLists(ctx): remove all user lists from storage (not from memory).
Default for "ctx" is target context.
- processAllEntries(ctx): process all entries in page. This is automatically
done at startup, so it should be manually called only for specific purposes.
Default for "ctx" is target context.
- startProcessing(ctx): start the timer that repeatedly processes the new
entries in page. This is automatically done at startup (if context
INTERVAL > MIN_INTERVAL), so it should be manually called only for specific
purposes (e.g. if previously stopped). Default for "ctx" is target context.
- stopProcessing(): stop the timer that repeatedly processes the new entries
in page. It works on both automatically and manually started timers.
Mandatory callback methods and variables in main context:
- name: identifier of the site (set with newContext())
- getPageEntries():
return (usually with getElementsByClassName or querySelectorAll) an array of
entries to be treated
- processItem(entry, entryData, processingType):
process the entry based on the processing type or other features of the entry
Conditionally mandatory callback methods in main context:
- getUser(): retrieve and return the username used on the website
mandatory if data are to be stored on a per-user basis
It can return either a single string (the username), or an object with a
'name' and a 'payload' property. Name is used as the username, payload is
saved in <ctx>.userPayload and can be used by context-specific functions
- getEntryData(entry): return an entryData object, that must have at least
an id property (used to identify the entry)
mandatory if you want to save entries to lists
NOTE: if id is not found, entry is skipped but it is not marked as invalid
for subsequent passes (unless you use TL.markInvalid(), see above)
- unProcessItem(entry, entryData, processingType):
like processItem, but it should reverse the action
mandatory for entries that have a toggle action added with
EL.addToggleEventOnClick()
Optional callback methods and variables in main context:
- interval: interval (in ms) to re-scan links in the DOM
won't re-scan if < MIN_INTERVAL (e.g. if it is set to 0)
dafault: DEFAULT_INTERVAL
- isEntryPage():
return false if page must not be scanned for entries
Default is always true => all pages contain entries
- getPageType():
return a truthy value (true, number, object) if page is significant to the
script for some reason (e.g. it is the page where lists are reloaded),
a falsy value otherwise. The result is stored in ctx.pageType.
Default is always false => no special page
- processPage(pageType, isEntryPage):
optionally do operations on page based on pageType (and isEntryPage).
Called only if pageType is truthy, so no need to check if that is false
- isValidEntry(entry):
return false if entry must be skipped
NOTE: if entry is skipped, it is not however marked as invalid for subsequent
passes (unless you use TL.markInvalid(), see above)
Default is always true => all entries returned by getPageEntries() are valid
- modifyEntry(entry):
optionally modify entry when scanned for the first time (e.g. add a button)
see also EL.addToggleEventOnClick() above
- inList(entryData, list):
check if entry is in list. Default is a simple lookup by entryData.id.
- determineType(lists, entryData, entry):
return the processing type for an entry given the lists it appears in (and
possibly other data), or a falsy value if no processing is required.
"lists" is an object with a true property for each list the entry appears in.
The decision can also be taken using name, id and properties of the entry.
If there is a single processing type, the method might as well return true/false
Default: return true if entry is in at least one list (especially useful in
cases with only one list, so there is no need to tell different lists apart)
Callback methods and variables in contexts for external sources:
- name: see above
- getUser(): see above
- getSourceUserFromTargetUser(targetContextName, targetUser):
return the user name on the source site corresponding to the one on target
site. This is needed to look for the saved lists.
Default is looking for the last saved user (single-user scenario).
A user payload can be downloaded as in getUser() (q.v.)
- getPageType(): see above
- processPage(pageType, isEntryPage): see above
- inList(entryData, list): see above
