OBJ) -> boolean</procedure> <procedure>(check-dirname LOCATION OBJECT [ARGNAM]) -> dirname</procedure> <procedure>(error-dirname LOCATION OBJECT [ARGNAM])</procedure> ==== check-directory ==== error-directory <procedure>(check-directory LOCATION OBJECT [ARGNAM]) -> directoryname</procedure> <procedure>(error-directory LOCATION OBJECT [ARGNAM])</procedure> Does the {{OBJECT}} name an existing {{directory}}> Does not reexport {{(chicken file posix) directory?}}. ==== pathname? ==== check-pathname ==== error-pathname <procedure>(pathname? OBJ) -> boolean</procedure> <procedure>(check-pathname LOCATION OBJECT [ARGNAM]) -> pathname</procedure> <procedure>(error-pathname LOCATION OBJECT [ARGNAM])</procedure> Does not verify existence of the file, just whether the pathname has a directory and/or file component. ==== filename? ==== check-filename ==== error-filename <procedure>(filename? OBJ) -> boolean</procedure> <procedure>(check-filename LOCATION OBJECT [ARGNAM]) -> filename</procedure> <procedure>(error-filename LOCATION OBJECT [ARGNAM])</procedure> Does not verify existence of the file, just whether it has a directory component. === Dotted Files & Directories Does not verify the existence of the subject directory or file. ==== Usage <enscript language=scheme> (import (directory-utils dotted)) </enscript> ==== dot-prefix-dirname? <procedure>(dot-prefix-dirname? DIRNAME) -> boolean</procedure> {{DIRNAME}} begins with a {{dot-prefix-dirname?}} ==== dot-suffix-dirname? <procedure>(dot-suffix-dirname? DIRNAME) -> boolean</procedure> {{DIRNAME}} ends with a {{dot-prefix-dirname?}} ==== dot-filename? <procedure>(dot-filename? FILENAME) -> boolean</procedure> Does the {{FILENAME}} name a file with a dot-name? ==== dot-pathname? <procedure>(dot-pathname? PATHNAME) -> boolean</procedure> Is any directory in the {{PATHNAME}} a dot-filename? Does not verify existence of the file! ==== remove-dotfiles <procedure>(remove-dotfiles FILES)</procedure> Remove dot files from a directory list. Useful with glob. ==== Directory Operations ==== Usage <enscript language=scheme> (import (directory-utils operations)) </enscript> ==== directory-foldl <procedure>(directory-foldl DIRECTORY FUNCTION SEED [SHOW-DOTFILES?]) -> *</procedure> Invokes {{FUNCTION}} on the recursive value from {{SEED}} and each {{filename}} in the {{DIRECTORY}} and . Returns the final value. ; {{FUNCTION}} : {{(* filename -> *)}}. ; {{SHOW-DOTFILES?}} : {{boolean}} ; include files with a {{"."}} prefix ; Default {{#f}}. ''Note'' that only the {{filename}} is passed and not the complete {{pathname}}. The {{"."}} and {{".."}} filenames are not supplied no matter the {{SHOW-DOTFILES?}} setting. On a ''Windows'' platform hidden files have a {{hidden}} attribute so this routine is rather ''*nix'' centric. ==== directory-unfold <procedure>(directory-unfold DIRECTORY TEST NEXT SEED [SHOW-DOTFILES?]) -> *</procedure> Walks {{DIRECTORY}}, visiting subdirectories based on {{TEST}}, and calling {{NEXT}} on the recursive value from {{SEED}} and each {{pathname}} in the directories. Returns the final value. Directories for which {{TEST}} fails are handled by {{NEXT}}. The passed {{pathname}} is a directory-separator suffixed {{dirname}}; example {{"b/"}}. ; {{TEST}} : {{(pathname -> 'a}} ; called with the full pathname. ; {{NEXT}} : {{('a pathname -> 'a)}} ; called with the full pathname. ; {{SEED}} : {{'a}}. ; {{SHOW-DOTFILES?}} : {{boolean}} ; include files with a {{"."}} prefix ; Default {{#f}}. ==== create-pathname-directory <procedure>(create-pathname-directory PATHNAME)</procedure> Ensures the directory component of {{PATHNAME}} exist. Like the ''*nix'' `"mkdir -p `dirname PATHNAME`" command. ==== make-program-filename <procedure>(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 <procedure>(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-in-directory? <procedure>(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 <procedure>(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 <procedure>(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! ==== find-command-pathnames <procedure>(find-command-pathnames COMMAND-NAME [ENVIRONMENT-VARIABLE]) -> (or #f (list-of pathname))</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 ''Windows'' {{#\;}}, and a ''*nix'' {{#\:}}. ==== which-command-pathname <procedure>(which-command-pathname COMMAND-NAME [ENVIRONMENT-VARIABLE]) -> (or #f pathname)</procedure> Same as which-command-pathnames but returns the first pathname only. Like the ''*nix'' `which COMMAND-NAME` command. === Directory Stack === Usage <enscript language=scheme> (import (directory-utils stack)) </enscript> ==== directory-utility-stack <parameter>(directory-utility-stack [STACK]) -> stack</parameter> Which {{stack}} to use for directory stack operations. {{stack}} is from [[stack]]. ==== push-directory <procedure>(push-directory DIRECTORY [STACK])</procedure> Push the current directory and change to the {{DIRECTORY}}. ; {{DIRECTORY}} : {{string}} ; pathname ; {{STACK}} : {{stack}} ; optional; default {{(directory-utility-stack)}} ==== pop-directory <procedure>(pop-directory [STACK]) -> string</procedure> Pop the last directory and change to it. ; {{STACK}} : {{stack}} ; optional; default {{(directory-utility-stack)}} ==== pop-toplevel-directory <procedure>(pop-toplevel-directory [STACK]) -> string</procedure> Pop the earliest directory and change to it. ; {{STACK}} : {{stack}} ; optional; default {{(directory-utility-stack)}} == Requirements [[srfi-1]] [[utf8]] [[miscmacros]] [[stack]] [[check-errors]] [[test]] [[test-utils]] == Author [[/users/kon-lovett|Kon Lovett]] == Repository This egg is hosted on the CHICKEN Subversion repository: [[https://anonymous@code.call-cc.org/svn/chicken-eggs/release/5/directory-utils|https://anonymous@code.call-cc.org/svn/chicken-eggs/release/5/directory-utils]] If you want to check out the source code repository of this egg and you are not familiar with Subversion, see [[/egg-svn-checkout|this page]]. == Version history ; 2.4.1 : Revert to "mkdir" as test find command.
