Return only "text" via selection

[mdroidian]

Requested from Christian K. via slack

Use Case

• the user is querying blocks that include text and an arbitrary amount of [[pages]], #tags, and {{buttons}}
• the user wants to display only the text
• as the number and location of the undesired parts of the block are indeterminate, this can be difficult to achieve with with node:node:/regex/

Proposed Solution

• add a new Selection data type that returns only text
  • eg: it removes any [[pages]], #tags, or {{buttons}}
• something like node:node:text-only

Unsure how we'd handle block references ((9EzwbaEJs)), especially when they contain [[pages]], #tags, or {{buttons}}

Workaround

For now, users can remove the undesired parts in embed view via css:

/* targeting Query Builder results table */
/* only from column titled "text" */

/* hide all [[links]] and #tags */
.roamjs-query-results-view td[data-column-title="text"] .rm-page-ref__brackets,
.roamjs-query-results-view td[data-column-title="text"] .rm-page-ref
{
    display:none;
}

/* hide checkboxes */
.roamjs-query-results-view td[data-column-title="text"] .check-container
{
    display:none;
}
