NAME

       calibre-debug - calibre-debug

          calibre-debug [options]

       Various  command  line  interfaces  useful  for  debugging  calibre. With no options, this
       command starts an embedded Python interpreter. You can also run the main calibre GUI,  the
       calibre viewer and the calibre editor in debug mode.

       It  also contains interfaces to various bits of calibre that do not have dedicated command
       line tools, such as font subsetting, the e-book diff tool and so on.

       You can also use calibre-debug to run standalone scripts. To do that use it like this:
          calibre-debug myscript.py -- --option1 --option2 file1 file2 ...

       Everything after the -- is passed to the script.

       Whenever you pass arguments to  calibre-debug  that  have  spaces  in  them,  enclose  the
       arguments in quotation marks. For example: "/some path/with spaces"

[OPTIONS]

       --add-simple-plugin
              Add a simple plugin (i.e. a plugin that consists of only a .py file), by specifying
              the path to the py file containing the plugin code.

       --command, -c
              Run Python code.

       --debug-device-driver, -d
              Debug device detection

       --default-programs
              (Un)register  calibre  from  Windows   Default   Programs.   --default-programs   =
              (register|unregister)

       --diff Run the calibre diff tool. For example: calibre-debug --diff file1 file2

       --edit-book, -t
              Launch the calibre "Edit book" tool in debug mode.

       --exec-file, -e
              Run the Python code in file.

       --explode-book, -x
              Explode  the  book  into  the  specified  directory. Usage: -x file.epub output_dir
              Exports the book as a collection of HTML files and metadata,  which  you  can  edit
              using standard HTML editing tools. Works with EPUB, AZW3, HTMLZ and DOCX files.

       --export-all-calibre-data
              Export  all  calibre data (books/settings/plugins). Normally, you will be asked for
              the export dir and the libraries to export. You can also specify  them  as  command
              line  arguments  to skip the questions. Use absolute paths for the export directory
              and libraries. The special keyword "all" can be used to export all libraries.

       --gui, -g
              Run the GUI with debugging enabled. Debug output is printed to stdout and stderr.

       --gui-debug
              Run the GUI with a debug console, logging to the specified path. For  internal  use
              only, use the -g option to run the GUI in debug mode

       --help, -h
              show this help message and exit

       --implode-book, -i
              Implode a previously exploded book. Usage: -i output_dir file.epub Imports the book
              from the files in output_dir which must have been created by  a  previous  call  to
              --explode-book. Be sure to specify the same file type as was used when exploding.

       --import-calibre-data
              Import previously exported calibre data

       --inspect-mobi, -m
              Inspect the MOBI file(s) at the specified path(s)

       --paths
              Output the paths necessary to setup the calibre environment

       --reinitialize-db
              Re-initialize  the sqlite calibre database at the specified path. Useful to recover
              from db corruption.

       --run-plugin, -r
              Run a plugin that provides a command line interface. For example: calibre-debug  -r
              "Add Books" -- file1 --option1 Everything after the -- will be passed to the plugin
              as arguments.

       --shutdown-running-calibre, -s
              Cause a running calibre instance, if any, to be shutdown. Note that  if  there  are
              running jobs, they will be silently aborted, so use with care.

       --subset-font, -f
              Subset  the  specified  font.  Use  -- after this option to pass option to the font
              subsetting program.

       --test-build
              Test binary modules in build

       --version
              show program's version number and exit

       --viewer, -w
              Run the E-book viewer in debug mode
