Automatically formatting content items for presentation

A non-transitory computer-readable medium including instructions that, when executed by a computing system, cause the computing system to perform operations comprising:

• receiving, by a content management system, an invocation of a presentation mode for a content item accessible to collaborators of the content item for editing and sharing;
• identifying, by the content management system, rules related to one or more indicia of importance, the rules comprising a first value corresponding to a first indicia of importance and a second value corresponding to a second indicia of importance, wherein the first indicia of importance corresponds to comments associated with a particular portion of content and wherein the second indicia of importance corresponds to a revision history associated with another particular portion of content;
• parsing, by the content management system, portions of content corresponding to the one or more indicia of importance and assigning values to each portion of content based on the identified rules;
• generating, by the content management system, a tree structure representation of the content item, where the tree structure representation includes a plurality of nodes corresponding to structure of content within the content item;
• generating, by the content management system, a presentation view based on the tree structure representation and the one or more indicia of importance by:
• traversing at least one node of the plurality of nodes in the tree structure representation;
• for the at least one node, determining whether a portion of content corresponding to the at least one node has an indicia of importance value above a threshold value, wherein the indicia of importance value is one of a first indicia of importance value corresponding to the first indicia of importance or a second indicia of importance value corresponding to the second indicia of importance;
• based on the determining, selecting first portions of content that have the indicia of importance value above the threshold value;
• and
• removing second portions of content that have the indicia of importance value below or at the threshold value;
• sending, by the content management system, the presentation view to a client device for display;
• storing, by the content management system, the presentation view for subsequent viewing;
• receiving, by the content management system, another request for a presentation mode for the content item;
• determining, by the content management system, that a current version of the content item corresponds to a version of the content item that was used for generating the presentation view;
• and
• based on the determining, providing, by the content management system, the presentation view without re-generating the presentation view.

A content management system, comprising:

• one or more processors;
• and
• a non-transitory computer-readable medium including one or more instructions that, when executed by the one or more processors, cause the content management system to perform operations comprising:
• receiving an invocation of a presentation mode for a content item accessible to collaborators of the content item for editing and sharing;
• identifying rules related to one or more indicia of importance, the rules comprising a first value corresponding to a first indicia of importance and a second value corresponding to a second indicia of importance, wherein the first indicia of importance corresponds to comments associated with a particular portion of content and wherein the second indicia of importance corresponds to a revision history associated with another particular portion of content;
• parsing portions of content corresponding to the one or more indicia of importance and assigning values to each portion of content based on the identified rules;
• generating a tree structure representation of the content item, where the tree structure representation includes a plurality of nodes, each node representing a structure of content within the content item;
• generating a presentation view by computing content sizing determinations based on presentation styles applied to labeled content in the content item, wherein generating the presentation view comprises:
• traversing at least one node of the plurality of nodes in the tree structure representation;
• for the at least one node, determining whether a portion of content corresponding to the at least one node has an indicia of importance value above a threshold value, wherein the indicia of importance value is one of a first indicia of importance value corresponding to the first indicia of importance or a second indicia of importance value corresponding to the second indicia of importance;
• based on the determining, selecting first portions of content that have the indicia of importance value above the threshold value;
• and
• removing second portions of content that have the indicia of importance value below or at the threshold value;
• and
• providing the generated presentation view;
• storing the presentation view for subsequent viewing;
• receiving another request for a presentation mode for the content item;
• determining that a current version of the content item corresponds to a version of the content item that was used for generating the presentation view;
• and
• based on the determining, providing the presentation view without re-generating the presentation view.
