can we Protect everything such as $\Xi_{cc}$ in title (do not let underscore becomes \_)

[Zhan-Wei Liu]

In my bib file, the title is well written as Latex form

@Article{Luo:2003q,
Title = {{Resolving the low mass puzzle of $\Xi_{cc}(2940)^+$}},
Author = {…},
…
}

With the following command and my own-written formatting-style.py even with Protected() function,

pybtex --style-language python someTexFile

The title in the someTexFile.bbl still becomes

\newblock {Resolving the low mass puzzle of $\Xi\_{cc}(2940)^+$}}.

That is, the underscore “_” becomes “\_”.

How can we do not let that happen and keep everything in title as the original one?

How to configure your reference style with pybtex (for beginners). Here I show more details after these days studying.

1. install pybtex
   pip install pybtex
2. install setuptools.
   pip install -U setuptools
3. we configure conf.py .

import latexcodec  # noqa
from pybtex.backends import BaseBackend

from pybtex.style.formatting.unsrt import Style as UnsrtStyle
from pybtex.style.labels.alpha import LabelStyle as AlphaLabelStyle
from pybtex.richtext import Symbol, Text, Protected, BaseMultipartText
from pybtex.style.formatting import BaseStyle, toplevel
from pybtex.style.template import (
    field, first_of, href, join, names, optional, optional_field, sentence,
    tag, together, words, FieldIsMissing
)
import re

class CustomStyle(UnsrtStyle):
    default_sorting_style = 'author_year_title'

    def get_article_template(self, entry):
        template = toplevel[
           self.format_myeprint(entry),
        ]
        return template

    def format_myeprint(self, entry):
        eprint  = self.optField(entry, 'eprint')
        if not eprint:
            return ''
        formatEprint=r'\ttfamily arXiv:%s' % eprint
        if href_YN:
            return r'\href{%s}{%s}' % (r'https://arxiv.org/abs/%s' % eprint, formatEprint )
        else:
            return  formatEprint

    def optField(self,entry, which_field):
        supField=''
        for key in entry.fields.keys():
            if which_field.lower()== key.lower():
                supField=entry.fields[which_field]
        for key in entry.persons.keys():
            if which_field.lower()== key.lower():
                supField=entry.persons[which_field]
        return supField

    def __init__(self, *args, **kwargs):
        super(CustomStyle, self).__init__(*args, **kwargs)

class myBackend(BaseBackend):
    ....
    def format_str(self, str_):
        #return codecs.encode(str_, self.latex_encoding)
        return str_


#in an entry, there are three parts: key, fields, and persons
#entry.fields['journal'] is an ordinary string
#entry.persons['author'] is an ordinary string
#entry.key is an ordinary string

4.write setupXX.py file and run the following command only once: python setupXX.py develop
In setupPR.py, we write

‌

from setuptools import setup

setup(name='PybtexPR plugins',
    py_modules=['conf'],
    entry_points = {
        'pybtex.style.formatting': 'customPR=conf:CustomStyle',
        'pybtex.backends': 'mybackend=conf:myBackend',
    },
)
 #the reference style file will be conf.py
 #customPR will be used in the .tex file; 
 #conf:CustomStyle will be defined in conf.py
 #register mybackend to solve the problem I raised

5. In your tex file, add
\bibliographystyle{customPR}
\bibliography{someBibFile}

and run the following command for generating the bbl file for the references:

pybtex --style-language python -b mybackend texfileName
