### wiki_page_compare Compare two pages, revisions, or text content to show differences between them. This tool provides comprehensive diff capabilities including HTML-formatted differences, metadata comparison, and slot-specific comparisons for multi-content revisions. **From Source Parameters (at least one required):** - `fromtitle` (string): Title of the first page to compare - `fromid` (integer): Page ID of the first page to compare - `fromrev` (integer): Revision ID of the first revision to compare **To Source Parameters (at least one required):** - `totitle` (string): Title of the second page to compare - `toid` (integer): Page ID of the second page to compare - `torev` (integer): Revision ID of the second revision to compare - `torelative` (string): Use a revision relative to the "from" revision. Options: "cur" (current), "next", "prev" **Content Override Parameters:** - `fromslots` (string): Pipe-separated list of slots to override in the "from" revision (e.g., "main") - `toslots` (string): Pipe-separated list of slots to override in the "to" revision (e.g., "main") - `frompst` (boolean): Apply pre-save transform to "from" content (default: false) - `topst` (boolean): Apply pre-save transform to "to" content (default: false) **Templated Slot Parameters for "from" side:** - `fromtext_main` (string): Custom text content for the main slot of the "from" revision - `fromsection_main` (string): Section identifier when using section content for the "from" revision - `fromcontentmodel_main` (string): Content model for the "from" text (e.g., "wikitext", "json", "css") - `fromcontentformat_main` (string): Content serialization format for the "from" text **Templated Slot Parameters for "to" side:** - `totext_main` (string): Custom text content for the main slot of the "to" revision - `tosection_main` (string): Section identifier when using section content for the "to" revision - `tocontentmodel_main` (string): Content model for the "to" text (e.g., "wikitext", "json", "css") - `tocontentformat_main` (string): Content serialization format for the "to" text **Output Control Parameters:** - `prop` (string): Pipe-separated list of information to include. Options: "comment", "diff", "diffsize", "ids", "parsedcomment", "rel", "size", "timestamp", "title", "user" (default: "diff|ids|title") - `slots` (string): Return individual diffs for specific slots rather than combined diff. Use "*" for all slots or pipe-separated slot names - `difftype` (string): Format of the diff output. Options: "table" (default), "inline", "unified" **Example Usage:** Compare two pages by title: ``` fromtitle: "Template:Example" totitle: "Template:Example/sandbox" prop: "diff|title|user|timestamp" ``` Compare specific revisions: ``` fromrev: 12345 torev: 12346 difftype: "unified" ``` Compare current revision to previous: ``` fromtitle: "Main Page" torelative: "prev" prop: "diff|diffsize|comment" ``` Compare with custom content: ``` fromrev: 12345 torev: 12346 fromslots: "main" fromtext_main: "Custom comparison text" fromcontentmodel_main: "wikitext" ``` **Return Format:** The tool returns a formatted text output containing: - Page/revision identification information - Diff size and metadata (timestamps, users, comments) if requested - HTML-formatted diff showing additions, deletions, and changes - Individual slot diffs if multiple slots are compared - Clear indication when no differences are found **Common Use Cases:** - Reviewing changes between page revisions - Comparing live pages with sandbox versions - Analyzing differences in template implementations - Checking content changes before publishing - Debugging page content issues by comparing known good revisions **Notes:** - At least one "from" parameter and one "to" parameter must be specified - Templated slot parameters use underscores in parameter names (e.g., `fromtext_main`) but are converted to hyphens internally (e.g., `fromtext-main`) - The diff HTML output is formatted for display in tables with appropriate CSS classes - Relative comparisons at the first or last revision of a page may produce special results as documented in the MediaWiki API
