(get-info/full path [ #:namespace namespace #:bootstrap? bootstrap?])
(or/c (->* (symbol?) ((-> any)) any) #f) path : path-string? namespace : (or/c namespace? #f) = #f bootstrap? : any/c = #f
The get-info/full function returns #f if there is no "info.rkt" (or "info.ss") file in the directory. If there is a "info.rkt" (or "info.ss") file that has the wrong shape (i.e., not a module using info or setup/infotab), or if the "info.rkt" file fails to load, then an exception is raised. If the "info.rkt" file loaded, get-info/full returns the get-info file. If the "info.rkt" file does not exist, then get-info/full does the same checks for the "info.ss" file, either raising an exception or returning the get-info function from the "info.ss" file.
The "info.rkt" (or "info.ss") module is loaded into namespace if it is not #f, or a private, weakly-held namespace otherwise.
If bootstrap? is true, then use-compiled-file-paths is set to '() while reading "info.rkt" (or "info.ss"), in case an existing compiled file is broken. Furthermore, the info and setup/infotab modules are attached to namespace from the namespace of get-info/full before attempting to load "info.rkt" (or "info.ss").
As the module is loaded, the environment variable set is pruned to contain only environment variables that are listed in the PLT_INFO_ALLOW_VARS environment variable, which contains a ;-separated list of names. By default, the list of allowed variable names is empty.
Changed in version 18.104.22.168 of package base: Added environment-variable pruning and PLT_INFO_ALLOW_VARS support.
Note that the cache may be out of date by the time you call get-info/full, so do not assume that every returned directory’s "info.rkt" file will supply one of the requested symbols.
The result is in a canonical order (sorted lexicographically by directory name), and the paths it returns are suitable for providing to get-info/full.
If mode is specified, it must be either
'preferred (the default), 'all-available,
'no-planet, or 'no-user. If mode is
'all-available, find-relevant-directories returns
all installed directories whose info files contain the specified
Collection links from the installation-wide collection links file or packages with installation scope are cached with the installation’s main "lib" directory, and links from the user-specific collection links file and packages are cached with the user-specific directory (build-path (find-system-path 'addon-dir) "collects") for all-version cases, and in (build-path (find-system-path 'addon-dir) (version) "collects") for version-specific cases.
