- (pathname? OBJ) procedure
Does not verify existence of the file, just whether it has dir+fil.
- (check-pathname LOCATION OBJECT [ARGNAM]) => * procedure
- (error-pathname LOCATION OBJECT [ARGNAM]) procedure
- (filename? OBJ) procedure
Does not verify existence of the file, just whether it doesn't have dir.
- (check-filename LOCATION OBJECT [ARGNAM]) => * procedure
- (error-filename LOCATION OBJECT [ARGNAM]) procedure
- (dot-filename? PATHNAME) => boolean procedure
Does the OBJECT name a file with a dot-name?
Does not verify existence of the file!
- (dot-pathname? PATHNAME) => boolean procedure
Is any dir in the PATHNAME a dot-filename?
Does not verify existence of the file!
- (check-directory LOCATION OBJECT [ARGNAM]) => * procedure
Does the OBJECT name an existing directory>
- (directory-fold FUNCTION IDENTITY DIRECTORY [#:dotfiles? DOTFILES?]) => * procedure
Invokes FUNCTION on each filename in the DIRECTORY and the recursive value from IDENTITY. Returns the final value.
Note that only the filename is passed and not the complete pathname. The "." and ".." filenames are not supplied no matter the DOTFILES? setting.
FUNCTION is a (procedure (filename *) *).
DOTFILES is a boolean indicating whether files with a "." prefix are included in the fold. Default is #f.
On a Windows platform hidden files have a hidden attribute so this routine is rather *nix centric.
- (create-pathname-directory PATHNAME) procedure
Ensures the directory component of PATHNAME exist.
Like the *nix `"mkdir -p `dirname PATHNAME`" command.
- (make-program-filename COMMAND) procedure
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 COMMAND) procedure
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/directory? FILENAME [DIRECTORY | DIRECTORY-LIST]) procedure
Returns the pathname when FILENAME exists in the DIRECTORY, otherwise #f.
DIRECTORY-LIST is as for make-pathname.
When only the FILENAME parameter supplied then the same as file-exists?.
- (find-file-pathnames FILENAME [DIRECTORY | DIRECTORY-LIST] ...) 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 COMMAND-NAME [DIRECTORY | DIRECTORY-LIST] ...) 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 COMMAND-NAME [ENVIRONMENT-VARIABLE]) procedure
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 #\; for Windows, and a #\: otherwise.
- (which-command-pathname COMMAND-NAME [ENVIRONMENT-VARIABLE]) procedure
Same as which-command-pathnames but returns the first pathname only.
Like the *nix `which COMMAND-NAME` command.
- (remove-dotfiles FILES) procedure
Remove dot files from a directory list. Useful with glob.
- (push-directory DIRECTORY) procedure
Push the current directory and change to the DIRECTORY.
- (pop-directory) procedure
Pop the last directory and change to it.
- (pop-toplevel-directory) procedure
Pop the earliest directory and change to it.
- Deprecated create-directory/parents.
