# Settings for latexindent: https://latexindentpl.readthedocs.io/en/latest

# 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.
fileExtensionPreference:
  .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: 1

# 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
