Fix off-by-one error



Fix common misspellings in text files. It's designed primarily for checking misspelled words in source code, but it can be used with other files as well.

Useful links


Python 2.7 or above.


You can use pip to install codespell with e.g.:

pip install codespell


Check usage with ./ -h. There are a few command line options. Note that upon installation with "make install" we don't have the "py" suffix. We ship a dictionary that is an improved version of the one available on Wikipedia after applying them in projects like Linux Kernel, EFL, oFono among others. You can provide your own version of the dictionary, but patches for new/different entries are very welcome.

Dictionary format

The format of the dictionary was influenced by the one it originally came from, i.e. from Wikipedia. The difference is how multiple options are treated and that the last argument is the reason why a certain entry could not be applied directly, but instead be manually inspected. E.g.:

  1. Simple entry: one wrong word / one suggestion:

  2. Entry with more than one suggested fix:

    fiel->feel, field, file, phial,

    Note the last comma! You need to use it, otherwise the last suggestion will be discarded (see below for why). When there are more than one suggestion, automatically fix is not possible and the best we can do is to give the user the file and line where the error occurred as well as the suggestions.

  3. Entry with one word, but with automatically fix disabled:

    clas->class, disabled because of name clash in c++

    Note that there isn't a comma in the end of the line. The last argument is treated as the reason why a suggestion cannot be automatically applied.
