# defaultSettings.yaml for latexindent.pl, version 3.7.1, 2019-09-07
#                      a script that aims to

# You should feel encouraged to change anything you like in these settings, but 
# it would probably be better to have your own user settings 
# files somewhere else - remember that this file may be overwritten
# when you update your tex distribution. Please see the manual linked from:
#
#       https://github.com/cmhughes/latexindent.pl
#
# for details of how to create and configure your own settings files.
#
# Please read the manual (linked from above) first to understand what each switch does.

# latexindent can be called to act on a file without using the file's extension, 
# e.g, simply
#       latexindent myfile
# in which case the choice of file extension is chosen
# according to the choices made in fileExtensionPreference
# Other file extensions can be added.

    .tex: 1
    .sty: 2
    .cls: 3
    .bib: 4

# default file extension of backup file (if -w switch is active)
# for example, if your .tex file is called
#       myfile.tex
# and you specify the backupExtension as BACKUP.bak then your 
# backup file will be
#       myfileBACKUP.bak
backupExtension: .bak

# only one backup per file: 
#   - if onlyOneBackUp is 0 then, as a safety measure, 
#     the number on the extension increments by 1 each time:
#
#           myfile.bak0, myfile.bak1, myfile.bak2
#   - if you set onlyOnebackUp to 1, then the backup file will
#     be overwritten each time (not recommended until you trust the script)
onlyOneBackUp: 0

# some users may want a finite number of backup files, 
# say at most 3; in which case, they can change this maxNumberOfBackUps.
#
# If maxNumberOfBackUps is set to 0 (or less) then infinitely 
# many backups are possible, unless onlyOneBackUp is switched on
maxNumberOfBackUps: 0

# some users may wish to cycle through back up files. 
#
# for example, with maxNumberOfBackUps: 4, they may 
# wish to delete the oldest back up file, and keep only the most recent.
#
#    copy myfile.bak1 to myfile.bak0
#    copy myfile.bak2 to myfile.bak1
#    copy myfile.bak3 to myfile.bak2
#    copy myfile.bak4 to myfile.bak3

# the back up will be written to myfile.bak4
