6.8 API for Finding Installation Directories
The
setup/dirs library provides several procedures for locating
installation directories:
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.
Returns a path to the user-specific "collects" directory; the
directory indicated by the returned path may or may not exist.
Returns a list of paths to installation
"collects"
directories, 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.
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.
Returns a path to the installation’s
collection links file. The file indicated by the
returned path may or may not exist.
Returns a path to the user’s
collection
links file. The file indicated by the returned path may or may not
exist.
Returns a list of paths to installation
collection links files that are 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
files indicated by the returned paths may or may not exist.
Returns a path to the directory containing packages with
installation scope; the directory indicated by the returned path may
or may not exist.
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.
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 directories indicated by the returned
paths may or may not exist.
Returns a path to the installation’s "doc" directory.
The result is #f if no such directory is available.
Returns a path to a user-specific "doc" directory. The directory
indicated by the returned path may or may not exist.
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.
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.
Returns a path to a user-specific "lib" directory; the directory
indicated by the returned path may or may not exist.
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.
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).
Returns a path to the
installation’s "share" directory, which contains installed
packages and other platform-independent files. The result is
#f if no such directory is available.
Returns a path to a user-specific "share" directory; the directory
indicated by the returned path may or may not exist.
Returns a path to the installation’s "include" directory, which
contains ".h" files for building Racket extensions and embedding
programs. The result is #f if no such directory is available.
Returns a path to a user-specific "include" directory; the
directory indicated by the returned path may or may not exist.
Returns a path to the installation’s executable directory, where the
stand-alone Racket executable resides. The result is #f if no
such directory is available.
Returns a path to the installation’s executable directory, where the
stand-alone GRacket executable resides. The result is #f if no such
directory is available.
Returns a path to the user’s executable directory; the directory
indicated by the returned path may or may not exist.
Returns a path to the user’s executable directory for graphical
programs; the directory indicated by the returned path may or may
not exist.
Returns a path to the installation’s directory ".desktop"
files (for Unix). The result is #f if no such directory
exists.
Returns a path to the user’s directory for ".desktop" files
(for Unix); the directory indicated by the returned path may or may
not exist.
Returns a path to the installation’s man-page directory. The result is
#f if no such directory exists.
Returns a path to the user’s man-page directory; the directory
indicated by the returned path may or may not exist.
Returns a string that is used by the documentation system, augmented
with a version and search-key query, for remote documentation links.
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.
Added in version 6.0.1.6 of package base.
Returns a string
that identifies an installation build, which can be used to augment
the Racket version number to more specifically identify the
build. An empty string is normally produced for a release build.
The result is #f if no build stamp is available.
Returns #t if this installation uses
absolute path names for executable and library references,
#f otherwise.
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.
The intent of this protocol is to support a kind of sandbox: an
installation that is more specific than user-specific, and where
copies of executables such as racket serve as entry points
into the sandbox. Assuming that the addon directory is set to a
directory other than the user’s default addon directory when
raco setup creates the executable copies, then further
package build and setup operations through the entry points will be
confined to the sandbox and not affect a user’s default environment.
