• Most scriptlet relies on Object properties (methods), altering them may not be the best idea (you should know what you are doing).
• Some properties related more to browser APIs rather than JS language built-ins can behave in unexpected way. For example browser can override them without scriptlet noticing this. Keep this in mind when using them in scriptlet injection filers.
• "Optional" for "string/regular expression" parameter defaults to "catch all" (/.?/) if not specified.
• "String" parameter means plain character(s)/word(s), quotes will be taken literally, commas must be escaped in regex literals: /foo\x2cbar\u002cbaz/, after 1.22.0 commas can be escaped by backslash character (foo\,bar).
• "Regular expression" parameter means JavaScript regular expression literal.
• Mime type is application/javascript if not present.
• You can use the short alias form when available for scriptlet name.
• You should omit the .js from the scriptlet name in scriptlet injection filters (eventually in some future this will be the official way to do this).
  • Do not skip .js when the scriptlet is used with redirect=, only when used in +js(...).
• Crossed out resources are deprecated/removed.
• Starting with 1.46.1b17 support for regex-based values as target domain has been added. Use sparingly, when no other solution is practical from a maintenance point of view -- keeping in mind that uBO has to iterate through all the regex-based values, unlike plain hostname or entity-based values which are mere lookups. Related discussion: uBlockOrigin/uBlock-issues#2234. Example: /img[a-z]{3,5}\.buzz/##+js(nowoif).
• The usage of named arguments is optional, positional arguments are still supported as documented. Named arguments is required to use "log" and/or "debug" arguments.
• The logging/debugging capabilities work only in the dev build of uBO or if the advanced setting filterAuthorMode is set to true.
• Starting with 1.57.3b1, the old method of displaying scriptlets's logs in browser's dev console and via (log, 1) tokens is deprecated:
  • now all scriptlets's logging output is automatically displayed in the logger & the logger's console pane.
  • in the logger, toggling labels info and error in filter input field can be used to reduce information displayed in the logger to informations and errors, including scriptlets, and with additional not operator selected, the opposite effect can be achieved.
  • in the logger's console pane, toggling additionally verbose mode button, will cause console pane to print more logs from scriptlets.
  • by default, scriptlets will print out only calls and informations related to their orders and targets,
    to log all calls without defusing any of them, a scriptlet without parameters can be used, example: wikipedia.org##+js(aeld)
  • related discussions: uBlockOrigin/uAssets/discussions/17907 and uBlockOrigin/uBlock-issues/discussions/3096
• The only filter lists deemed from a "trusted source" are uBO-specific filter lists (i.e. "uBlock filters -- ..."). The user's own filters from "My filters" are trusted only if "Allow custom filters requiring trust" is checked or in the dev build of uBO. This behaviour can be overridden with the advanced setting trustedListPrefixes.
• Tokens are parameters which modify the behavior of a scriptlet, they must be used after the required and optional parameters.
