PyCDSL 0.4.0

Access various dictionaries from CDSL (Cologne Digital Sanskrit Lexicon)

PyCDSL is a python interface to Cologne Digital Sanskrit Lexicon (CDSL).

• Free software: GNU General Public License v3

• Documentation: https://pycdsl.readthedocs.io.

Features

• CDSL Corpus Management (Download, Update, Access)

• Unified Programmable Interface to access all dictionaries available at CDSL

• Console Command and REPL Interface for easy dictionary search

• Extensive support for transliteration using indic-transliteration module

Usage

PyCDSL can be used in a python project, as a console command and as an interactive REPL interface.

Using PyCDSL in a Project

Import PyCDSL in a project:

import pycdsl

Create a CDSLCorpus Instance:

# Default installation at ~/cdsl_data
CDSL = pycdsl.CDSLCorpus()

# Custom installation path can be specified with argument `data_dir`
# e.g. CDSL = pycdsl.CDSLCorpus(data_dir="custom-installation-path")

# Custom transliteration schemes for input and output can be specified
# with arguments `input_scheme` and `output_scheme`.
# Values should be valid names of the schemes from `indic-transliteration`
# If unspecified, `DEFAULT_SCHEME` (`devanagari`) would be used.

CDSL = pycdsl.CDSLCorpus(input_scheme="itrans", output_scheme="iast")

Setup default dictionaries (["MW", "MWE", "AP90", "AE"]):

# Note: Any additional dictionaries that are installed will also be loaded.
CDSL.setup()

# For loading specific dictionaries only,
# a list of dictionary IDs can be passed to the setup function
# e.g. CDSL.setup(["VCP"])

# If `update` flag is True, update check is performed for every dictionary
# in `dict_ids` and if available, the updated version is installed
# e.g. CDSL.setup(["MW"], update=True)

Search in a dictionary:

# Any loaded dictionary is accessible through `dicts` using dictionary ID
# e.g. CDSL.dicts["MW"]
results = CDSL.dicts["MW"].search("राम")

# Alternatively, they are also accessible like an attribute
# e.g. CDSL.MW, CDSL.MWE etc.
results = CDSL.MW.search("राम")

# Note: Attribute access actually uses the `dicts` property under the hood
# to access the dictionaries.
# >>> CDSL.MW is CDSL.dicts["MW"]
# True

# `input_scheme` and `output_scheme` can be specified to the search function.
CDSL.MW.search("kṛṣṇa", input_scheme="iast", output_scheme="itrans")[0]
# <MWEntry: 55142: kRRiShNa = 1. kRRiShNa/ mf(A/)n. black, dark, dark-blue (opposed to shveta/, shukla/, ro/hita, and aruNa/), RV.; AV. &c.>

# Search using wildcard (i.e. `*`)
# e.g. To search all etnries starting with kRRi (i.e. कृ)
CDSL.MW.search("kRRi*", input_scheme="itrans")

# Limit and/or Offset the number of search results, e.g.
# Show the first 10 results
CDSL.MW.search("kṛ*", input_scheme="iast", limit=10)
# Show the next 10 results
CDSL.MW.search("kṛ*", input_scheme="iast", limit=10, offset=10)

Access an entry by ID:

entry = CDSL.MW.entry("263938")

# >>> entry
# <MWEntry: 263938: हृषीकेश = lord of the senses (said of Manas), BhP.>

# Output transliteration scheme can also be provided

CDSL.MW.entry("263938", output_scheme="iast")
# <MWEntry: 263938: hṛṣīkeśa = lord of the senses (said of Manas), BhP.>

Entry class also supports transliteration after creation. Thus, any entry fetched either through search() function or through entry() function can be transliterated.

Transliterate a single entry:

CDSL.MW.entry("263938").transliterate("slp1")
# <MWEntry: 263938: hfzIkeSa = lord of the senses (said of Manas), BhP.>

Change transliteration scheme for a dictionary:

CDSL.MW.set_scheme(input_scheme="itrans")
CDSL.MW.search("rAma")

Note: Please check the documentation of modules in the PyCDSL Package for more detailed information on available classes and functions.

optional arguments:
-h, --help          show this help message and exit
-i, --interactive   Start in an interactive REPL mode
-s SEARCH, --search SEARCH
                    Search pattern. Ignored if `--interactive` mode is set.
-p PATH, --path PATH  Path to installation
-d DICTS [DICTS ...], --dicts DICTS [DICTS ...]
                    Dictionary IDs
-is INPUT_SCHEME, --input-scheme INPUT_SCHEME
                    Input transliteration scheme
-os OUTPUT_SCHEME, --output-scheme OUTPUT_SCHEME
                    Output transliteration scheme
-u, --update        Update the specified dictionaries.
-dbg, --debug       Turn debug mode on.
-v, --version       Show version and exit.

Note: Arguments for specifying installation path, dictionary IDs, input and output transliteration schemes are valid for both interactive REPL shell and non-interactive console command.
