Diacritics Library

This library is used for adding, and removing diacritics from strings.

Getting started

Start by importing the module:

import dcl

DCL currently supports a multitude of diacritics:

  • acute
  • breve
  • caron
  • cedilla
  • grave
  • interpunct
  • macron
  • ogonek
  • ring
  • ring_and_acute
  • slash
  • stroke
  • stroke_and_acute
  • tilde
  • tittle
  • umlaut/diaresis
  • umlaut_and_macron

Each accent has their own attribute which is directly accessible from the dcl module.

>>> 'á'

These attributes return a Character object, which is essentially just a handy "wrapper"
around our diacritic, which we can use to access various attributes to retrieve further
information about the diacritic we're focusing on.

char = dcl.ogonek('a')

>>> "<ogonek 'ą'>"

char.character  # the same as str(char)
>>> 'ą'

char.diacritic  # some return <unprintable>
>>> '˛'

>>> 'ogonek'

char.raw  # returns the raw representation of our character
>>> '\U00000105'

>>> '\U000002db'

Some functions can't take certain letters. For example, the letter h cannot take
a cedilla diacritic. In this case, an exception is raised named DiacriticError.
You can access this exception via dcl.errors.DiacriticError.

from dcl.errors import DiacriticError

    char = dcl.cedilla('h')
except DiacriticError as e:

>>> 'Character h cannot take a cedilla diacritic'

If you want to, you may also use the DiacriticApplicant object from
dcl.objects. The functions you see above use this object too, and it's virtually
the same principle, except from the fact that we use properties to get the
diacritic, and the class simply holds the string and it's properties. Alas with the
functions above, this object also returns the same Character object through it's properties.

from dcl.objects import DiacriticApplicant

da = DiacriticApplicant('a')
>>> "<ogonek 'ą'>"

There is also the clean_diacritics function, accessible straight from the dcl module.
This function allows us to completely clean a string from any diacritics.

>>> 'Kreusada'

>>> 'Cafe'

Along with this function, there's also count_diacritics, get_diacritics and has_diacritics.

The has_diacritics function simply checks if the string contains a character
with a diacritic.

>>> True

>>> False

The get_diacritics function is used to get all the diacritics in a string.
It returns a dictionary. For each diacritic in the string, the key will show
the diacritic's index in the string, and the value will show the Character

>>> {3: <acute 'é'>}

>>> {2: <umlaut 'ë'>, 3: <circumflex 'û'>, 4: <caron 'š'>, 5: <grave 'à'>, 7: <ring 'å'>}

The count_diacritics function counts the number of diacritics in a string. The actual
implementation of this simply returns the dictionary length from get_diacritics.

>>> 1

Creating an end user program

Creating a program would be pretty simple for this, and I'd love to be able to help
you out with a base idea. Have a look at this for example:

import dcl
import string

from dcl.errors import DiacriticError

char = str(input("Enter a character: "))
if not char in string.ascii_letters:
    print("Please enter a letter from a-Z.")
    accent = str(input("Enter an accent, you can choose from the following: " + ", ".join(dcl.diacritic_list)))
    if not dcl.isdiacritictype(accent):
        print("That was not a valid accent.")
            function = getattr(dcl, accent)  # or dcl.objects.DiacriticApplicant
            output = function(char)
        except DiacriticError as e:

It's worth checking if the provided accent is a diacritic type. If it is, then you can use getattr.
Without checking, the user could provide a default global such as __file__.

You can also create a program which can remove diacritics from a string. It's made easy!

import dcl

string = str(input("Enter the string which you want to be cleared from diacritics: "))
print("Here is your cleaned string: " + dcl.clean_diacritics(string))

Or perhaps your program wants to count the number of diacritics contained
within your string.

import dcl

string = str(input("This program will count the number of diacritics contained in your input. Enter a string: "))
count = dcl.count_diacritics(string)
if count == 1:
    grammar = "is"
    grammar = "are"
print(f"There {grammar} {count} diacritics/accent in your string.")
