Which will return True if the passed in word is recognized by the dictionaryįor the current book’s language. Its most useful method is dictionaries.recognized(word) This represents the collection of dictionaries used for spell checking theĬurrent book. Useful attributes include, title, authors (a list of authors) and This represents the metadata of the current book, such as title, authors, In canonical form, a path relative to the root of the book, using / as the Searching inside marked text, the file_name is empty. This is the filename of the file in which the current match was found. Replace All, every successive match will cause replace() to beĬalled with an increasing number. The number argument is the number of the current match. Text corresponding to individual capture groups in the search regular Its most useful method is group() which can be used to get the matched The match argument represents the currently found match. The various arguments to the replace() function are If no replacements are to be done, it should return oup() which is When a find/replace is run, for every match that is found, the replace()įunction will be called, it must return the replacement string for that match. The API for the function mode ¶Īll function mode functions must be Python functions named replace, with theĭef replace ( match, number, file_name, metadata, dictionaries, data, functions, * args, ** kwargs ): return a_string You would be better off using the dedicated Table of Contents tool in If you really needed to generate a Table of Contents from headings in your book, This was just a demonstration to show you the power of function mode, Replace() one extra time after all matches have been found. True on the replace() function means that the editor will call The data object is a Pythonĭict that persists between all successive invocations of replace() duringĪnother new feature is the use of call_after_last_match – setting that to Key new feature is the use of another useful extra argument to the The function above is heavily commented, so it should be easy to follow. HTML Table of Contents, ready to be pasted into toc.html. Window will popup with “Debug output from your function” which will have the Run the search on All text files and at the end of the search, a call_after_last_match = True # Ensure that when running over multiple files, this function is called, # the files are processed in the order in which they appear in the book replace. ![]() group () # We don't want to make any actual changes, so return the original matched text # Ensure that we are called once after the last match is found so we can # output the ToC replace. append (( file_name, tag_name, anchor, text )) return match. language ) print ( xml2str ( toc )) else : print ( 'No headings to build ToC from found' ) else : # Add an entry corresponding to this match to the Table of Contents if 'toc' not in data : # The entries are stored in the data object, which will persist # for all invocations of this function during a 'Replace All' operation data = tag_name, anchor, text = match. add ( text, file_name, anchor ) toc = toc_to_html ( root, current_container (), 'toc.html', 'Table of Contents for ' + metadata. # The argument metadata is the metadata of the book being edited if 'toc' in data : toc = data root = TOC () for ( file_name, tag_name, anchor, text ) in toc : parent = root. You can create a custom function that willĪutomatically number these headings with consecutive section numbers, so thatįrom calibre import replace_entities from .toc import TOC, toc_to_html from _book import current_container from import xml2str def replace ( match, number, file_name, metadata, dictionaries, data, functions, * args, ** kwargs ): if match is None : # All matches found, output the resulting Table of Contents. Here, we will leverage one of the builtin functions in the editor toĪutomatically change the case of all text inside heading tags to title case: Automatically fixing the case of headings in the document ¶ Techniques for using function mode and the syntax will be described by means ofĮxamples, showing you how to create functions to perform progressively moreĬomplex tasks. You to do lots of things that are not possible with simple templates. In function mode, instead of using a fixed template, you Regular expression to search for as well as a template that is used to replaceĪll found matches. ![]() In the standard regexp mode for search and replace, you specify both a In this mode, you can combine regular expressions (see All about using regular expressions in calibre) withĪrbitrarily powerful Python functions to do all sorts of advanced text The Search & replace tool in the editor support a function mode.
