parse-string

Returns parsed `yaml-string` as Clojure data structures. Valid `& opts` (`opts` are keyword args, see [docs](/doc/01-user-guide.adoc#keyword-args)): - `:key-fn` - Single-argument fn, arg is a map with `:key`; called on YAML keys, return replaces YAML key. - default behaviour: see `:keywords` - overrides `:keywords`, consider using this option instead of `:keywords` - see [docs](/doc/01-user-guide.adoc#key-conv) - `:keywords` - when `true` attempts to convert YAML keys to Clojure keywords, else makes no conversion - default: `true`. - ignored when `:key-fn` is specified - when clj-yaml detects that a YAML key cannot be converted to a legal Clojure keyword it leaves the key as is. - detection is not sophisticated and clj-yaml will produce invalid Clojure keywords, so although our default is `true` here, `false` can be a better choice. - consider instead using `:key-fn` - see [docs](/doc/01-user-guide.adoc#key-conv) - `:load-all` - when `true` loads all YAML documents from `yaml-string` and returns a vector of parsed docs. Else only first YAML document is loaded, and return is that individual parsed doc. - default: `false` - `:unknown-tag-fn` - Single-argument fn, arg is map with keys `:tag` and `:value`; return replaces the YAML tag and value. - default behaviour: clj-yaml throws on unknown tags. - see [docs](/doc/01-user-guide.adoc#unknown-tags) for example usage. - `:max-aliases-for-collections` the maximum number of YAML aliases for collections (sequences and mappings). - Default: `50` - throws when value is exceeded. - `:nesting-depth-limit` the maximum number of nested YAML levels. - Default: `50` - throws when value is exceeded. - `:code-point-limit` the maximum number of code points (document size). - Default: `3145728` - throws when value is exceeded. - `:allow-recursive-keys` - when `true` allows recursive keys for mappings. Only checks the case where the key is the direct value. - Default: `false` - `:allow-duplicate-keys` - when `false` throws on duplicate keys. - Default: `true` - last duplicate key wins. - `:unsafe` - when `true` attempt to load tagged elements to Java objects, else prohibits via throw. - default: `false` - **WARNING**: be very wary of parsing unsafe YAML. See [docs](/doc/01-user-guide.adoc#unsafe) - `:mark` - when `true` position of YAML input is tracked and returned in alternate structure. - default: `false` - see [docs](/doc/01-user-guide.adoc#mark) Note: clj-yaml will only recognize the first of `:unsafe`, `:mark` or `:unknown-tag-fn`
