For more information about this release, see https://github.com/github/codeql-cli-binaries/releases.\n>\n> To see details of the options available for this command in an earlier release, run the command with the <span style=\"white-space: nowrap;\">`--help`</span> option in your terminal.\n\n## Synopsis\n\n```shell copy\ncodeql query decompile [--output=<file>] <options>... -- <file>\n```\n\n## Description\n\n\\[Plumbing] Read an intermediate representation of a compiled query\nfrom a .qlo file.\n\nThe code will be written to standard output, unless the `--output`\noption is specified.\n\n## Options\n\n### Primary Options\n\n#### `<file>`\n\n\\[Mandatory] QLO file to read from.\n\n#### `-o, --output=<file>`\n\nThe file to write the desired output to.\n\n#### `--kind=<kind>`\n\nThe kind of the intermediate representation to read. The options are:\n\n`dil`: A Datalog intermediate representation.\n\n`ra`: A relational algebra intermediate representation. This is used by\nthe query evaluation phase.\n\n`bytecode`: Show the raw (uncompressed) bytecode from the .qlo file.\nMostly useful for debugging the compiler/evaluator.\n\nThe default is `dil` if the query was compiled with\n`--include-dil-in-qlo` and `ra` otherwise\n\n### Common options\n\n#### `-h, --help`\n\nShow this help text.\n\n#### `-J=<opt>`\n\n\\[Advanced] Give option to the JVM running the command.\n\n(Beware that options containing spaces will not be handled correctly.)\n\n#### `-v, --verbose`\n\nIncrementally increase the number of progress messages printed.\n\n#### `-q, --quiet`\n\nIncrementally decrease the number of progress messages printed.\n\n#### `--verbosity=<level>`\n\n\\[Advanced] Explicitly set the verbosity level to one of errors,\nwarnings, progress, progress+, progress++, progress+++. Overrides `-v`\nand `-q`.\n\n#### `--logdir=<dir>`\n\n\\[Advanced] Write detailed logs to one or more files in the given\ndirectory, with generated names that include timestamps and the name of\nthe running subcommand.\n\n(To write a log file with a name you have full control over, instead\ngive `--log-to-stderr` and redirect stderr as desired.)\n\n#### `--common-caches=<dir>`\n\n\\[Advanced] Controls the location of cached data on disk that will\npersist between several runs of the CLI, such as downloaded QL packs and\ncompiled query plans. If not set explicitly, this defaults to a\ndirectory named `.codeql` in the user's home directory; it will be\ncreated if it doesn't already exist.\n\nAvailable since `v2.15.2`."}
