export.format_prons

[සංස්කරණය]

function export.format_prons(data)

Function to parse arguments and format one or more pronunciations. Meant to be called from a module. `data` is a table

containing the following fields:
  • `lang` (required): Language object for the respellings.
  • `raw_args` (required): Unparsed arguments, generally taken from frame:getParent().args.
  • `respelling_to_IPA` (required): Function to generate one or more pronunciations given respelling. On input, the function is passed a single object `data` with the following fields:
    • `respelling`: The respelling.
    • `orig_respelling`: The original respelling; may be nil or `+` (which is substituted with the pagename).
    • `item`: The item parsed from the argument containing the respelling, along with inline modifiers and separate parameters.
    • `args`: The parsed `args` table generated from `raw_args`.
    • `pagename`: The pagename, either taken from `args.pagename` or from the actual pagename.
     The function should return either a string (the respelling); a table with the respelling in the `pron` field and
    
     optional left and right regular and/or accent qualifiers in (respectively) `q`, `qq`, `a` and `aa`; a list of
    
     respelling strings; or a list of respelling+qualifier tables. If regular or accent qualifiers are returned, they will
    
     be combined with any user-specified qualifiers (which go first).
    
  • `track_module` (recommended): Name of the invoking module, for debug-tracking purposes.
  • `include_bullet`: If specified, a bullet (`*`) will be added before the generated pronunciation. When this is given, extra parameters |bullets= (to override the number of added bullets) and |pre= (to specify text to insert between the bullets and the generated pronunciation) will be available. Use of this field is not recommended; it is provided for compatibility only.
  • `augment_params`: If specified, a key-value table of arguments to add to the `params` table, prior to parsing the raw arguments using `process` in Module:parameters. See Module:fr-pron for an example of specifying this field.
  • `augment_param_mod_spec`: If specified, a list of specs of the form accepted by `construct_param_mods()` in Module:parameter utilities to add to the default specs (which specify the following inline modifiers and separate parameters: |q= and <q:...>; |qq= and <qq:...>; |a= and <a:...>; |aa= and <aa:...>; and |ref= and <ref:...>. See Module:fr-pron for an example of specifying this field.

--[==[ intro:
This module provides utilities to simplify and standardize the creation of pronunciation modules, particularly when it
comes to argument parsing. Using this module, it should only be necessary to provide the function that actually converts
respelling to IPA.

--[==[
Function to parse arguments and format one or more pronunciations. Meant to be called from a module. `data` is a table
containing the following fields:<ul>
<li> `lang` ('''required'''): Language object for the respellings.
<li> `raw_args` ('''required'''): Unparsed arguments, generally taken from {frame:getParent().args}.
<li> `respelling_to_IPA` ('''required'''): Function to generate one or more pronunciations given respelling. On input, the
  function is passed a single object `data` with the following fields:<ul>
  <li> `respelling`: The respelling.
  <li> `orig_respelling`: The original respelling; may be {nil} or `+` (which is substituted with the pagename).
  <li> `item`: The item parsed from the argument containing the respelling, along with inline modifiers and separate
     parameters.
  <li> `args`: The parsed `args` table generated from `raw_args`.
  <li> `pagename`: The pagename, either taken from `args.pagename` or from the actual pagename.</ul>
  The function should return either a string (the respelling); a table with the respelling in the `pron` field and
  optional left and right regular and/or accent qualifiers in (respectively) `q`, `qq`, `a` and `aa`; a list of
  respelling strings; or a list of respelling+qualifier tables. If regular or accent qualifiers are returned, they will
  be combined with any user-specified qualifiers (which go first).
<li> `track_module` ('''recommended'''): Name of the invoking module, for debug-tracking purposes.
<li> `include_bullet`: If specified, a bullet (`*`) will be added before the generated pronunciation. When this is given,
  extra parameters {{para|bullets}} (to override the number of added bullets) and {{para|pre}} (to specify text to
  insert between the bullets and the generated pronunciation) will be available. '''Use of this field is not
  recommended; it is provided for compatibility only.'''
<li> `augment_params`: If specified, a key-value table of arguments to add to the `params` table, prior to parsing the
  raw arguments using `process` in [[Module:parameters]]. See [[Module:fr-pron]] for an example of specifying this
  field.
<li> `augment_param_mod_spec`: If specified, a list of specs of the form accepted by `construct_param_mods()` in
  [[Module:parameter utilities]] to add to the default specs (which specify the following inline modifiers and separate
  parameters: {{para|q}} and {{cd|<q:...>}}; {{para|qq}} and {{cd|<qq:...>}}; {{para|a}} and {{cd|<a:...>}};
  {{para|aa}} and {{cd|<aa:...>}}; and {{para|ref}} and {{cd|<ref:...>}}. See [[Module:fr-pron]] for an example of
  specifying this field.
