Convert among Devanagari transliteration systems

Project description

Devanagari Transliterators

Convert among common Devanagari transliteration systems. The following codecs are currently implemented.

System Code Decoder Encoder
Devanagari dev
Hardvard Kyoto hk
IAST iast
ITRANS itrans
SLP1 slp
(La)TeX tex
Velthuis vel
WX wx


The best method to install is via pip.

pip3 install devtrans

Clone the GitLab repository to install from the source.


As a script

transliterate -d dev -e iast -i input_file -o outputfile

The options

  • -d Decoder system code (defaults todev)
  • -e Encoder system code (defaults to iast)
  • -i Input file (defaults to STDIN)
  • -o Output file (defaults to STDOUT)

See help for more details

transliterate --help

As a module

Import the module.

import devtrans

Call any codec function with appropriate input text

target = devtrans.wx2iast('xevanAgarI')

Devanagari encoders can have an optional boolean argument. If True, which is default, the encoder transliterates digits to Devanagari digits. If False, it leaves digits as it is.

target = devtrans.wx2dev('BagavaxgIwA 18.78', False)


It has primarily been developed for personal use as a tea-time activity. Some of my colleagues and I are using it since 2015 for general texts from classical literature. I have been tweaking and making modifications whenever we found an issue. However, the transliterators are not tested exhaustively or thoroughly with various kinds of texts.

Majority of the transliteration schemes are case-sensitive. Currently, encoder/decoder for case-insensitve schemes works with lowercase characers only.

Many schemes use punctuation characters to represent letters which are represented using alphabets in another scheme. This makes punctuated text to be poorly transliterated. No character-escape mechanism is used.


Find the repo on GitLab. If found bugs, please fix and push them, raise an issue or mail me.
