Changelog

2.0.0 (2018-04-30)

(#108)

Features

  • The gtts module
    • New logger (“gtts”) replaces all occurrences of print()
    • Languages list is now obtained automatically (gtts.lang) (#91, #94, #106)
    • Added a curated list of language sub-tags that have been observed to provide different dialects or accents (e.g. “en-gb”, “fr-ca”)
    • New gTTS() parameter lang_check to disable language checking.
    • gTTS() now delegates the text tokenizing to the API request methods (i.e. write_to_fp(), save()), allowing gTTS instances to be modified/reused
    • Rewrote tokenizing and added pre-processing (see below)
    • New gTTS() parameters pre_processor_funcs and tokenizer_func to configure pre-processing and tokenizing (or use a 3rd party tokenizer)
    • Error handling:
      • Added new exception gTTSError raised on API request errors. It attempts to guess what went wrong based on known information and observed behaviour (#60, #106)
      • gTTS.write_to_fp() and gTTS.save() also raise gTTSError on gtts_token error
      • gTTS.write_to_fp() raises TypeError when fp is not a file-like object or one that doesn’t take bytes
      • gTTS() raises ValueError on unsupported languages (and lang_check is True)
      • More fine-grained error handling throughout (e.g. request failed vs. request successful with a bad response)
  • Tokenizer (and new pre-processors):
    • Rewrote and greatly expanded tokenizer (gtts.tokenizer)
    • Smarter token ‘cleaning’ that will remove tokens that only contain characters that can’t be spoken (i.e. punctuation and whitespace)
    • Decoupled token minimizing from tokenizing, making the latter usable in other contexts
    • New flexible speech-centric text pre-processing
    • New flexible full-featured regex-based tokenizer (gtts.tokenizer.core.Tokenizer)
    • New RegexBuilder, PreProcessorRegex and PreProcessorSub classes to make writing regex-powered text pre-processors and tokenizer cases easier
    • Pre-processors:
      • Re-form words cut by end-of-line hyphens
      • Remove periods after a (customizable) list of known abbreviations (e.g. “jr”, “sr”, “dr”) that can be spoken the same without a period
      • Perform speech corrections by doing word-for-word replacements from a (customizable) list of tuples
    • Tokenizing:
      • Keep punctuation that modify the inflection of speech (e.g. “?”, “!”)
      • Don’t split in the middle of numbers (e.g. “10.5”, “20,000,000”) (#101)
      • Don’t split on “dotted” abbreviations and accronyms (e.g. “U.S.A”)
      • Added Chinese comma (“，”), ellipsis (“…”) to punctuation list to tokenize on (#86)
  • The gtts-cli command-line tool
    • Rewrote cli as first-class citizen module (gtts.cli), powered by Click
    • Windows support using setuptool’s entry_points
    • Better support for Unicode I/O in Python 2
    • All arguments are now pre-validated
    • New --nocheck flag to skip language pre-checking
    • New --all flag to list all available languages
    • Either the --file option or the <text> argument can be set to “-” to read from stdin
    • The --debug flag uses logging and doesn’t pollute stdout anymore

Bugfixes

  • _minimize(): Fixed an infinite recursion loop that would occur when a token started with the miminizing delimiter (i.e. a space) (#86)
  • _minimize(): Handle the case where a token of more than 100 characters did not contain a space (e.g. in Chinese).
  • Fixed an issue that fused multiline text together if the total number of characters was less than 100
  • Fixed gtts-cli Unicode errors in Python 2.7 (famous last words) (#78, #93, #96)

Deprecations and Removals

  • Dropped Python 3.3 support
  • Removed debug parameter of gTTS (in favour of logger)
  • gtts-cli: Changed long option name of -o to --output instead of --destination
  • gTTS() will raise a ValueError rather than an AssertionError on unsupported language

Improved Documentation

Misc

  • Major test re-work
  • Language tests can read a TEST_LANGS enviromment variable so not all language tests are run every time.
  • Added AppVeyor CI for Windows
  • PEP 8 compliance

Misc

  • Update LICENCE, add to manifest (#77)
