CALIBRE-DEBUG(1) calibre CALIBRE-DEBUG(1) NAME calibre-debug - calibre-debug calibre-debug [] 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 E-book 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 -e myscript.py -- --option1 --option2 file1 file2 ... Everything after the -- is passed to the script. You can also use calibre-debug as a shebang in scripts, like this: #!/usr/bin/env -S calibre-debug -e -- -- :command: ` calibre-debug`: "/some path/with spaces" [] --add-simple-plugin py .py --command, -c Python --debug-device-driver, -d --default-programs Windows / calibre --default-programs = (register|unregister) --diff calibre diff calibre-debug --diff file1 file2 --edit-book --exec-file, -e Python --explode-book, -x -x file.epub output_dir HTML HTML EPUBAZW3HTMLZ DOCX --export-all-calibre-data Export all calibre data (books/settings/plugins). Normally, you will be asked for the export folder and the libraries to export. You can also specify them as command line arguments to skip the questions. Use absolute paths for the export folder and libraries. The special keyword "all" can be used to export all libraries. Examples: calibre-debug --export-all-calibre-data # for interactive use calibre-debug --export-all-calibre-data /path/to/empty/export/folder /path/to/library/folder1 /path/to/library2 calibre-debug --export-all-calibre-data /export/folder all # export all known libraries --fix-multiprocessing --gui, -g Debug stdout stderr --gui-debug GUI -gGUI --help, -h --implode-book, -i -i output_dir file.epub output_dir --explode-book --import-calibre-data calibre --inspect-mobi, -m MOBI --paths calibre --run-plugin, -r Run a plugin that provides a command line interface. For example: calibre-debug -r "Plugin name" -- file1 --option1 Everything after the -- will be passed to the plugin as arguments. --run-test, -t Run the named test(s). Use the special value "all" to run all tests. If the test name starts with a period it is assumed to be a module name. If the test name starts with @ it is assumed to be a category name. --run-without-debug Don't run with the DEBUG flag set --shutdown-running-calibre, -s calibre --subset-font, -f -- --test-build --version --viewer, -w AUTHOR Kovid Goyal COPYRIGHT Kovid Goyal 7.17.0 8 23, 2024 CALIBRE-DEBUG(1)
