Build the given font package, applying all of PHASES in order.

Like 'git-fetch', fetch COMMIT from URL into DIRECTORY, but fall back to alternative methods when fetching from URL fails: attempt to download a nar for ITEM, and if that also fails, download from the Software Heritage archive. When HASH and HASH-ALGORITHM are provided, they are interpreted as the nar hash of the directory of interested and are used as its content address at SWH.

Fetch COMMIT from URL into DIRECTORY. COMMIT must be a valid Git commit identifier. When LFS? is true, configure Git to also fetch Large File Storage (LFS) files; it assumes that the git-lfs extension is available in the environment. When RECURSIVE? is true, all the sub-modules of URL are fetched, recursively. Return #t on success, #f otherwise.

Generate the loaders.cache file used by gdk-pixbuf to locate the available loaders among DIRECTORIES, and set the GDK_PIXBUF_MODULE_FILE environment variable. The cache file is installed under OUTPUTS. Return the first cache file name if one was created else #f.

Build the given package, applying all of PHASES in order.

Create a procedure that installs an early bootstrap package. The procedure will install all of the '.scm' and '.go' files in each of the directories in MODULES, and all the executable files in the SCRIPTS directory.

Create a procedure that configures an early bootstrap package. The procedure will search each directory in MODULES and configure all of the '.in' files with NAME and VERSION. It will then search the SCRIPTS directory and configure all of the '.in' files with the bootstrap Guile and its module and object directories.

Create a procedure that builds an early bootstrap package. The procedure will search each directory in MODULES and compile all of the '.scm' files.

Build from SOURCE to OUTPUTS, using INPUTS, and by running all of PHASES in order. Return #t if all the PHASES succeeded, #f otherwise.

Dump to PORT the contents of files in DIRECTORY that match FILE-REGEXP.

Build the given Go package, applying all of PHASES in order.

Copy DIRECTORY to OUTPUT, replacing strings according to MAPPING, a list of file name pairs.

Read data from INPUT, replacing store references according to REPLACEMENT-TABLE, and writing the result to OUTPUT. REPLACEMENT-TABLE is a vhash that maps strings (original hashes) to bytevectors (replacement strings comprising the replacement hash, a dash, and a string).

Note: We use string keys to work around the fact that guile-2.0 hashes all bytevectors to the same value.

Apply the grafts described by MAPPING on OLD-OUTPUTS, leading to NEW-OUTPUTS. MAPPING must be a list of file name pairs; OLD-OUTPUTS and NEW-OUTPUTS are lists of output name/file name pairs.
