directory-utils

Note that only the filename is passed and not the complete pathname. The "." and ".." filenames are not supplied no matter the DOTFILES? setting.

On a Windows platform hidden files have a hidden attribute so this routine is rather *nix centric.

create-pathname-directory

create-pathname-directory PATHNAMEprocedure

Ensures the directory component of PATHNAME exist.

Like the *nix `"mkdir -p `dirname PATHNAME`" command.

make-program-filename

make-program-filename COMMANDprocedure

Returns the platform specific form of an executable command filename.

On Windows the "exe" extension is added unless an extension is already present. Does nothing otherwise.

make-shell-filename

make-shell-filename COMMANDprocedure

Returns the platform specific form of a shell command filename.

On Windows the "bat" extension is added unless an extension is already present. Otherwise conditionally adds the "sh" extension.

file-exists-in-directory?

(file-exists-in-directory? FILENAME [DIRECTORY ...]) -> (or #f pathname)procedure

Returns the pathname when FILENAME exists in the DIRECTORY ..., otherwise #f.

DIRECTORY ... as make-pathname.

When only the FILENAME argument supplied then the same as file-exists?.

find-file-pathnames

(find-file-pathnames FILENAME [DIRECTORY | DIRECTORY-LIST] ...) -> (or #f (list-of pathname))procedure

Returns a list of all pathnames found for FILENAME in the supplied directory/directories, or #f when not found.

The list of pathnames is in the same relative order as that of the directory parameter(s).

find-program-pathnames

(find-program-pathnames COMMAND-NAME [DIRECTORY | DIRECTORY-LIST] ...) -> (or #f (list-of pathname))procedure

Returns a list of all pathnames found for COMMAND-NAME in the supplied directory/directories, or #f when not found.

Uses make-program-filename to make a filename.

On Windows also uses make-shell-filename to make a filename.

Does not ensure that the file is executable!

which-command-pathnames

which-command-pathnames COMMAND-NAME #!optional ENVIRONMENT-VARIABLEprocedure

Returns the pathnames of COMMAND-NAME in the ENVIRONMENT-VARIABLE where the file exists, or #f when nothing found.

The default ENVIRONMENT-VARIABLE is "PATH".

Uses the platform specific "PATH" environment variable element separator - a Windows #\;, and a *nix #\:.

which-command-pathname

which-command-pathname COMMAND-NAME #!optional ENVIRONMENT-VARIABLEprocedure

Same as which-command-pathnames but returns the first pathname only.

Like the *nix `which COMMAND-NAME` command.

remove-dotfiles

remove-dotfiles FILESprocedure: Remove dot files from a directory list. Useful with glob.

Directory Stack

directory-utility-stack

directory-utility-stack #!optional STACKparameter

Which stack to use for directory stack operations.

stack is from stack.

push-directory

push-directory DIRECTORY #!optional STACKprocedure

Push the current directory and change to the DIRECTORY.

DIRECTORY: string ; pathname
STACK: stack ; optional; default (directory-utility-stack)

pop-directory

pop-directory #!optional STACKprocedure

Pop the last directory and change to it.

STACK: stack ; optional; default (directory-utility-stack)

pop-toplevel-directory

pop-toplevel-directory #!optional STACKprocedure

Pop the earliest directory and change to it.

STACK: stack ; optional; default (directory-utility-stack)
