File system utilities in Clojure

*cwd* clj

Current working directory. This cannot be changed in the JVM. Changing this will only change the working directory for functions in this library.

absolute clj

(absolute path)

Return absolute file.

absolute? clj

(absolute? path)

Return true if path is absolute.

base-name clj

(base-name path)

(base-name path trim-ext)

Return the base name (final segment/file part) of a path.

If optional trim-ext is a string and the path ends with that string, it is trimmed.

If trim-ext is true, any extension is trimmed.

chdir clj

(chdir path)

set!s the value of *cwd* to path. Only works inside of with-mutable-cwd

child-of? clj

(child-of? p c)

Takes two paths and checks to see if the first path is a parent of the second.

chmod clj

(chmod mode path)

Change file permissions. Returns path.

mode can be a permissions string in octal or symbolic format. Symbolic: any combination of r (readable) w (writable) and x (executable). It should be prefixed with + to set or - to unset. And optional prefix of u causes the permissions to be set for the owner only. Octal: a string of three octal digits representing user, group, and world permissions. The three bits of each digit signify read, write, and execute permissions (in order of significance). Note that group and world permissions must be equal.

Examples:

(chmod "+x" "/tmp/foo") ; Sets executable for everyone
(chmod "u-wx" "/tmp/foo") ; Unsets owner write and executable

copy clj

(copy from to)

Copy a file from from to to. Return to.

copy+ clj

(copy+ src dest)

Copy src to dest, create directories if needed.

copy-dir clj

(copy-dir from to)

Copy a directory from from to to. If to already exists, copy the directory to a directory with the same name as from within the to directory.

copy-dir-into clj

(copy-dir-into from to)

Copy directory into another directory if destination already exists.

create clj

(create f)

Create a new file.

delete clj

(delete path)

Delete path.

delete-dir clj

(delete-dir root & link-options)

Delete a directory tree. Optional link-options may be provided to determine whether or not to follow symbolic links.

directory? clj

(directory? path & link-options)

Return true if path is a directory, false otherwise. Optional link-options may be provided to determine whether or not to follow symbolic links.

ephemeral-dir clj

(ephemeral-dir prefix)

(ephemeral-dir prefix suffix)

(ephemeral-dir prefix suffix tries)

Create an ephemeral directory (will be deleted on JVM exit). Returns nil if dir could not be created even after n tries (default 10).

ephemeral-file clj

(ephemeral-file prefix)

(ephemeral-file prefix suffix)

(ephemeral-file prefix suffix tries)

Create an ephemeral file (will be deleted on JVM exit). Returns nil if file could not be created even after n tries (default 10).

exec clj

(exec & body)

Execute a shell command in the current directory

executable? clj

(executable? path)

Return true if path is executable.

exists? clj

(exists? path)

Return true if path exists.

expand-home clj

(expand-home path)

If path begins with a tilde (~), expand the tilde to the value of the user.home system property. If the path begins with a tilde immediately followed by some characters, they are assumed to be a username. This is expanded to the path to that user's home directory. This is (naively) assumed to be a directory with the same name as the user relative to the parent of the current value of user.home.

extension clj

(extension path)

Return the extension part of a file.

file clj

(file path & paths)

If path is a period, replaces it with cwd and creates a new File object out of it and paths. Or, if the resulting File object does not constitute an absolute path, makes it absolutely by creating a new File object out of the paths and cwd.

file? clj

(file? path)

Return true if path is a file.

find-files clj

(find-files path pattern)

Find files matching given pattern.

find-files* clj

(find-files* path pred)

Find files in path by pred.

glob clj

(glob pattern)

(glob root pattern)

Returns files matching glob pattern.

hidden? clj

(hidden? path)

Return true if path is hidden.

home clj

(home)

(home user)

With no arguments, returns the current value of the user.home system property. If a user is passed, returns that user's home directory. It is naively assumed to be a directory with the same name as the user located relative to the parent of the current value of user.home.

iterate-dir clj

(iterate-dir path)

Return a sequence [root dirs files], starting from path in depth-first order

link clj

(link new-file existing-file)

Create a "hard" link from path to target. The arguments are in the opposite order from the link(2) system call.

link? clj

(link? path)

Return true if path is a link.

list-dir clj

(list-dir path)

List files and directories under path.

mkdir clj

(mkdir path)

Create a directory.

mkdirs clj

(mkdirs path)

Make directory tree.

mod-time clj

(mod-time path)

Return file modification time.

move clj

(move source target & copy-options)

Move or rename a file to a target file. Optional copy-options may be provided.

name clj

(name path)

Return the name part of a file.

normalized clj

(normalized path)

Return normalized (canonical) file.

ns-path clj

(ns-path n)

Takes a namespace symbol and creates a path to it. Replaces hyphens with underscores. Assumes the path should be relative to cwd.

parent clj

(parent path)

Return the parent path.

parents clj

(parents f)

Get all the parent directories of a path.

path-ns clj

(path-ns path)

size clj

(size path)

Return size (in bytes) of file.

split clj

(split path)

split-ext clj

Create a "soft" link from path to target.

temp-dir clj

(temp-dir prefix)

(temp-dir prefix suffix)

(temp-dir prefix suffix tries)

Create a temporary directory. Returns nil if dir could not be created even after n tries (default 10).

temp-file clj

(temp-file prefix)
