To simplify the level of + processing required, Mastodon metadata frontmatter has been limited + to only allow those characters in the `c-printable` set, as defined + by the YAML 1.2 specification, instead of permitting those from the + `nb-json` characters inside double-quoted strings like YAML proper. + ¶ It is important to note that Mastodon only borrows the *syntax* + of YAML, not its semantics. This is to say, Mastodon won't make any + attempt to interpret the data it receives. `true` will not become a + boolean; `56` will not be interpreted as a number. Rather, each key + and every value will be read as a string, and as a string they will + remain. The order of the pairs is unchanged, and any duplicate keys + are preserved. However, YAML escape sequences will be replaced with + the proper interpretations according to the YAML 1.2 specification. + ¶ The implementation provided below interprets `<br>` as `\n` and + allows for an open <p> tag at the beginning of the bio. It replaces + the escaped character entities `'` and `"` with single or + double quotes, respectively, prior to processing. However, no other + escaped characters are replaced, not even those which might have an + impact on the syntax otherwise. These minor allowances are provided + because the Mastodon backend will insert these things automatically + into a bio before sending it through the API, so it is important we + account for them. Aside from this, the YAML frontmatter must be the + very first thing in the bio, leading with three consecutive hyphen- + minues (`---`), and ending with the same or, alternatively, instead + with three periods (`...`). No limits have been set with respect to + the number of characters permitted in the frontmatter, although one + should note that only limited space is provided for them in the UI. + ¶ The regular expression used to check the existence of, and then + process, the YAML frontmatter has been split into a number of small + components in the code below, in the vain hope that it will be much + easier to read and to maintain. I leave it to the future readers of + this code to determine the extent of my successes in this endeavor. + + Sending love + warmth eternal, + - kibigo [@kibi@glitch.social] + +\*********************************************************************/ + +/* CONVENIENCE FUNCTIONS */ + +const unirex = str => new RegExp(str, 'u');
