Module Stog.EngineSource

Rewrite engine.

Sourceexception Cant_open_cache_file of string

Exception raised when a cache file of a loaded plugin could not be open.

Sourcetype 'a level_fun =
  1. | Fun_stog of Types.stog XR.env -> Types.stog -> Types.Doc_set.t -> Types.stog
  2. | Fun_data of 'a XR.env -> (Types.stog * 'a) -> Types.Doc_set.t -> Types.stog * 'a
  3. | Fun_stog_data of (Types.stog * 'a) XR.env -> (Types.stog * 'a) -> Types.Doc_set.t -> Types.stog * 'a

A function associated to a level. All functions take in parameter the environment, the stog and structure and the list of documents to rewrite. They return the new stog structure. Some function (Fun_data, Fun_stog_data) also handle an additional data structure: the callbacks in the environment also handle it, and the function returns it with the stog structure.

Sourcetype 'a modul = {
  1. mod_data : 'a;
  2. mod_levels : 'a level_fun Types.Int_map.t;
  3. mod_name : string;
}

A structure containing data and functions associated to levels. Contains also the module name.

Sourcemodule type Module = sig ... end

A module.

Sourceval generate : ?use_cache:bool -> ?gen_cache:bool -> ?default_style:XR.tree list -> ?only_docs:string list -> Types.stog -> (module Module) list -> unit

Generate the target files, with the following steps:

  • create the output directory,
  • build the base environment from the site global attributes,
  • compute by-topic, by-keyword and by-month documents,
  • compute documents,
  • for each level, for each document, apply level functions on the document
  • output Types.doc.doc_out field in the destination file. @use_cache reuse documents from cache, default is true @gen_cache update cache, default is true
Sourceval doc_dst_file : Types.stog -> Types.doc -> string

Build the final file where the given document will be generated.

Sourceval doc_url : Types.stog -> Types.doc -> Url.t

Build the final url of the given document.

Sourceval get_in_args_or_env : 'a -> 'a XR.env -> XR.attributes -> Stog.Types.Xml.name -> 'a * XR.tree list

get_in_args_or_env env args s returns the value associated to s in args of else return the result of get_in_env env s.

Sourceval get_path : 'a -> 'a XR.env -> 'a * Path.path

get_path env returns the path associated to "doc-path" in env.

  • raises Path.Invalid

    if "doc-path" is not found in the environment or is not a valid path.

Sourceval get_path_in_args_or_env : 'a -> 'a XR.env -> XR.attributes -> 'a * Path.path

Same as get_path but first looks for "doc-path" attribute in the given args.
