#### 6.8`` API for Finding Installation Directories

(require setup/dirs) | package: base

The setup/dirs library provides several procedures for locating installation directories. Many of these paths can be configured through the configuration directory (see Installation Configuration and Search Paths).

In cross-platform build mode (see API for Cross-Platform Configuration), the functions provided by setup/dirs generally report target-system paths, instead of current-system paths. The exceptions are get-lib-search-dirs and find-dll-dir, which report current-system paths while get-cross-lib-search-dirs and find-cross-dll-dir report target-system paths.

> > procedure

> > (find-collects-dir) → (or/c path? #f)

Returns a path to the installation’s main "collects" directory, or #f if none can be found. A #f result is likely only in a stand-alone executable that is distributed without libraries.

> > procedure

> > (find-user-collects-dir) → path?

Returns a path to the user-specific "collects" directory; the directory indicated by the returned path may or may not exist.

The user-specific path depends on at least (find-system-path 'addon-dir) and (get-installation-name).

> > procedure

> > (get-collects-search-dirs) → (listof path?)

Returns the same result as (current-library-collection-paths), which means that this result is not sensitive to the value of the use-user-specific-search-paths parameter.

> > procedure

> > (get-main-collects-search-dirs) → (listof path?)

Returns a list of paths to installation "collects" directories, normally including the result of find-collects-dir. These directories are normally included in the result of (current-library-collection-paths), but a PLTCOLLECTS setting or change to the parameter may cause them to be omitted. Any other path in (current-library-collection-paths) is treated as user-specific. The directories indicated by the returned paths may or may not exist.

The main-collections search path can be configured via 'collects-search-dirs in "config.rktd" (see Installation Configuration and Search Paths).

> > procedure

> > (find-config-dir) → (or/c path? #f)

Returns a path to the installation’s "etc" directory, which contains configuration and package information—including configuration of some of the other directories (see Installation Configuration and Search Paths). A #f result indicates that no configuration directory is available.

> > procedure

> > (find-links-file) → (or/c path? #f)

Returns a path to the installation’s collection links file. The file indicated by the returned path may or may not exist. A #f result indicates that no links file is available.

See also 'links-file in Installation Configuration and Search Paths.

> > procedure

> > (find-user-links-file [vers]) → path?

> vers : string? = (get-installation-name)

Returns a path to the user’s collection links file. The file indicated by the returned path may or may not exist.

The user-specific path depends on at least (find-system-path 'addon-dir) and vers.

> > procedure

> > (get-links-search-files) → (listof path?)

Returns a list of paths to installation collection links files to search in order. (Normally, the result includes the result of (find-links-file), which is where new installation-wide links are installed by raco link or links.) The result of find-user-links-file is not added to the returned list. The files indicated by the returned paths may or may not exist.

See also 'links-search-files in Installation Configuration and Search Paths.

> > procedure

> > (find-pkgs-dir) → (or/c path? #f)

Returns a path to the directory containing packages with installation scope; the directory indicated by the returned path may or may not exist. A #f result indicates that no package-installation directory is available.

See also 'pkgs-dir in Installation Configuration and Search Paths.

> > procedure

> > (find-user-pkgs-dir [vers]) → path?

> vers : string? = (get-installation-name)

Returns a path to the directory containing packages with user-specific scope for installation name vers; the directory indicated by the returned path may or may not exist.

The user-specific path depends on at least (find-system-path 'addon-dir) and vers.

> > procedure

> > (get-pkgs-search-dirs) → (listof path?)

Returns a list of paths to the directories containing packages in installation scope. (Normally, the result includes the result of (find-pkgs-dir), which is where new packages are installed by raco pkg install.) The result of find-user-pkgs-dir is not added to the returned list. The directories indicated by the returned paths may or may not exist.

See also 'pkgs-search-dirs in Installation Configuration and Search Paths.

> > procedure

> > (find-doc-dir) → (or/c path? #f)

Returns a path to the installation’s "doc" directory. The result is #f if no such directory is available.

See also 'doc-dir in Installation Configuration and Search Paths.

> > procedure

> > (find-user-doc-dir) → path?

Returns a path to a user-specific "doc" directory. The directory indicated by the returned path may or may not exist.

The user-specific path depends on at least (find-system-path 'addon-dir) and (get-installation-name).

> > procedure

> > (get-doc-search-dirs) → (listof path?)

Returns a list of paths to search for documentation, not including documentation stored in individual collections. Unless it is configured otherwise, the result includes any non-#f result of (find-doc-dir) and (find-user-doc-dir)—but the latter is included only if the value of the use-user-specific-search-paths parameter is #t.

See also 'doc-search-dirs in Installation Configuration and Search Paths.

> > procedure

> > (get-doc-extra-search-dirs) → (listof path?)

Like get-doc-search-dirs, but refrains from adding (find-doc-dir) and (find-user-doc-dir) to the underlying 'doc-search-dirs configuration.

Added in version 8.1.0.6 of package base.

> > procedure

> > (find-lib-dir) → (or/c path? #f)

Returns a path to the installation’s "lib" directory, which contains libraries and other build information. The result is #f if no such directory is available.

See also 'lib-dir in Installation Configuration and Search Paths.

> > procedure

> > (find-user-lib-dir) → path?

Returns a path to a user-specific "lib" directory; the directory indicated by the returned path may or may not exist.

The user-specific path depends on at least (find-system-path 'addon-dir) and (get-installation-name).

> > procedure

> > (get-lib-search-dirs) → (listof path?)

Returns a list of paths to search for foreign libraries.

Unless it is configured otherwise, and except in cross-platform build mode, the result includes any non-#f result of (find-lib-dir) and (find-user-lib-dir)—but the latter is included only if the value of the use-user-specific-search-paths parameter is #t.

In cross-platform build mode (see API for Cross-Platform Configuration), get-lib-search-dirs reports a result suitable for the current system, instead of the target system. See also get-cross-lib-search-dirs.

See also 'lib-search-dirs in Installation Configuration and Search Paths.

Changed in version 6.1.1.4 of package base: Dropped (find-dll-dir) from the set of paths to explicitly include in the default.
Changed in version 6.9.0.1: Changed behavior in cross-platform build mode.

> > procedure

> > (get-cross-lib-search-dirs) → (listof path?)

> > procedure

> > (get-cross-lib-extra-search-dirs) → (listof path?)

Like get-cross-lib-search-dirs, but refrains from adding (find-lib-dir) and (find-user-lib-dir) to the underlying 'lib-search-dirs configuration.

> > procedure

> > (find-dll-dir) → (or/c path? #f)

Returns a path to the directory that contains DLLs for use with the current executable (e.g., "libracket.dll" on Windows). The result is #f if no such directory is available, or if no specific directory is available (i.e., other than the platform’s normal search path).

In cross-platform build mode (see API for Cross-Platform Configuration), find-dll-dir reports a result suitable for the current system, instead of the target system. See also find-cross-dll-dir.

Changed in version 6.9.0.1 of package base: Changed behavior in cross-platform build mode.

Added in version 8.1.0.6 of package base.

> > procedure

> > (find-apps-dir) → (or/c path? #f)

Returns a path to the installation’s directory ".desktop" files (for Unix). The result is #f if no such directory exists.

See also 'apps-dir in Installation Configuration and Search Paths.

> > procedure

> > (get-doc-open-url) → (or/c string? #f)

Returns #f or a string for a root URL to be used as an alternative to opening a local file for documentation. A non-#f configuration means that DrRacket, for example, performs keyword searches for documentation via the specified URL instead of from locally installed documentation.

See also 'doc-open-url in Installation Configuration and Search Paths.

Added in version 6.0.1.6 of package base.

> > procedure

> > (get-installation-name) → string?

Returns the current installation’s name, which is often (version) but can be configured via 'installation-name in "config.rktd" (see Installation Configuration and Search Paths).

> > procedure

> > (get-build-stamp) → (or/c #f string?)

Returns a path to a user-specific directory to hold an extra copy of each installed executable, where the extra copy is created by raco setup and tethered to a particular result for (find-system-path 'addon-dir) and (find-config-dir).

Unlike other directories, which are configured via "config.rktd" in the (find-config-dir) directory (see Installation Configuration and Search Paths), these paths are configured via 'addon-tethered-console-bin-dir and 'addon-tethered-gui-bin-dir entries in "config.rktd" in (build-path (find-system-path 'addon-dir) "etc"). If no configuration is present, the result from the corresponding function, find-addon-tethered-console-bin-dir or find-addon-tethered-gui-bin-dir, is #f instead of a path.

See Tethered Installations for more information.

Added in version 6.5.0.2 of package base.

> > procedure

> > (find-config-tethered-console-bin-dir) → (or/c #f path?)

> > procedure

> > (find-config-tethered-gui-bin-dir) → (or/c #f path?)

Similar to find-addon-tethered-console-bin-dir and find-addon-tethered-gui-bin-dir, but configured via "config.rktd" in the (find-config-dir) directory (see Installation Configuration and Search Paths) and triggers executables that are tethered only to a particular value of (find-config-dir).

See Tethered Installations for more information.

Added in version 6.5.0.2 of package base.
