## Synopsis
|
|
|
|
```shell copy
|
|
codeql generate overlay-changes [--source-root=<dir>] [--output=<file>] <options>... -- <database>
|
|
```
|
|
|
|
## Description
|
|
|
|
\[Plumbing] Generate a file that can be used for the
|
|
`--overlay-changes` option to
|
|
[codeql database create](/code-security/codeql-cli/codeql-cli-manual/database-create) when extracting an overlay database.
|
|
|
|
This command is intended to be used mostly for manual or automated
|
|
testing. It is not particularly efficient. For production use, consider
|
|
if the changes file can instead be derived from something like
|
|
`git diff --name-only`.
|
|
|
|
## Options
|
|
|
|
### Primary Options
|
|
|
|
#### `<database>`
|
|
|
|
\[Mandatory] Path to the _base_ database into which the overlay will be
|
|
extracted.
|
|
|
|
#### `-s, --source-root=<dir>`
|
|
|
|
The directory containing the source code to be extracted as an overlay.
|
|
If not given, the current working directory is used.
|
|
|
|
#### `-o, --output=<file>`
|
|
|
|
The changes file will be written to this location. If it is not
|
|
specified, the changes will be written to standard output.
|
|
|
|
### Common options
|
|
|
|
#### `-h, --help`
|
|
|
|
Show this help text.
|
|
|
|
#### `-J=<opt>`
|
|
|
|
\[Advanced] Give option to the JVM running the command.
|
|
|
|
(Beware that options containing spaces will not be handled correctly.)
|
|
|
|
#### `-v, --verbose`
|
|
|
|
Incrementally increase the number of progress messages printed.
|
|
|
|
#### `-q, --quiet`
|
|
|
|
Incrementally decrease the number of progress messages printed.
|
|
|
|
#### `--verbosity=<level>`
|
|
|
|
\[Advanced] Explicitly set the verbosity level to one of errors,
|
|
warnings, progress, progress+, progress++, progress+++. Overrides `-v`
|
|
and `-q`.
|
|
|
|
#### `--logdir=<dir>`
|
|
|
|
\[Advanced] Write detailed logs to one or more files in the given
|
|
directory, with generated names that include timestamps and the name of
|
|
the running subcommand.
|
|
|
|
(To write a log file with a name you have full control over, instead
|
|
give `--log-to-stderr` and redirect stderr as desired.)
|
|
|
|
#### `--common-caches=<dir>`
|
|
|
|
\[Advanced] Controls the location of cached data on disk that will
|
|
persist between several runs of the CLI, such as downloaded QL packs and
|
|
compiled query plans. If not set explicitly, this defaults to a
|
|
directory named `.codeql` in the user's home directory; it will be
|
|
created if it doesn't already exist.
|
|
|
|
Available since `v2.15.2`.
