3.2 Environment Variables ¶

Since there is no configuration file for ‘cpt’, the package manager is configured through environment variables. These can be set per operation, or be set to your shell configuration or ‘~/.profile’. Here are the environment variables that alter the behaviour of ‘cpt’, some of them have separate sections to provide detailed information.

CPT_PATH ¶

Set the locations of your repositories. It is similar to the PATH variable.

CPT_CACHE ¶

The cache directory for ‘cpt’. Default: $XDG_CACHE_HOME/cpt.

CPT_CHOICE ¶

If this is set to 0, a package installation will be aborted on conflicts.

CPT_COLOR ¶

If this is set to 1, ‘cpt’ tools will be forced to display coloured output. If set to 0, they will be forced to display them without colours. Otherwise, ‘cpt’ will output colour as long as it is outputting to a terminal.

CPT_DEBUG ¶

If set to 1, temporary directories will not be removed after the operation.

CPT_DOWNLOADER

The tool to be used to download package sources. One of ‘curl’, ‘wget’, ‘wget2’, ‘axel’, ‘aria2c’. Defaults to the first one found in that order.

CPT_FETCH ¶

If set to 0, cpt-update will not fetch repositories.

CPT_FORCE ¶

If set to 1, ‘cpt’ tools will force operation.

CPT_HOOK ¶

Absolute path to the package manager hook file.

CPT_KEEPLOG ¶

If set to 1, ‘cpt’ will keep logs regardless of operation success.

CPT_NOSTRIP ¶

If set to 1, ‘cpt’ will not strip debug information from the binaries. Keep in mind that your compiler already strips most debug information during compilation, so you also need to add -g flag to your $C{XX}FLAGS

CPT_PID ¶

Set the temporary build directory name.

CPT_PROMPT ¶

If set to 0, ‘cpt’ will not prompt you for anything.

CPT_REPO_CACHE ¶

If set to 0, ‘cpt’ will not use or write repository information cache.

CPT_ROOT ¶

If this variable is set, ‘cpt’ will assume the given path as the system root.

CPT_TEST ¶

If set to 1, cpt-build will run tests whenever available.

CPT_TMPDIR ¶

The directory to create the temporary directories.

CPT_VERBOSE ¶

If this variable is set to 1, the package manager will print more information.
