- #elvdoc:var list-separator
- #
- # OS-specific path list separator. Colon (`:`) on UNIX and semicolon (`;`) on
- # Windows. This variable is read-only.
- #elvdoc:var separator
- #
- # OS-specific path separator. Forward slash (`/`) on UNIX and backslash (`\`)
- # on Windows. This variable is read-only.
- #elvdoc:fn abs
- #
- # ```elvish
- # path:abs $path
- # ```
- #
- # Outputs `$path` converted to an absolute path.
- #
- # ```elvish-transcript
- # ~> cd ~
- # ~> path:abs bin
- # ▶ /home/user/bin
- # ```
- #elvdoc:fn base
- #
- # ```elvish
- # path:base $path
- # ```
- #
- # Outputs the last element of `$path`. This is analogous to the POSIX `basename` command. See the
- # [Go documentation](https://pkg.go.dev/path/filepath#Base) for more details.
- #
- # ```elvish-transcript
- # ~> path:base ~/bin
- # ▶ bin
- # ```
- #elvdoc:fn clean
- #
- # ```elvish
- # path:clean $path
- # ```
- #
- # Outputs the shortest version of `$path` equivalent to `$path` by purely lexical processing. This
- # is most useful for eliminating unnecessary relative path elements such as `.` and `..` without
- # asking the OS to evaluate the path name. See the [Go
- # documentation](https://pkg.go.dev/path/filepath#Clean) for more details.
- #
- # ```elvish-transcript
- # ~> path:clean ./../bin
- # ▶ ../bin
- # ```
- #elvdoc:fn dir
- #
- # ```elvish
- # path:dir $path
- # ```
- #
- # Outputs all but the last element of `$path`, typically the path's enclosing directory. See the
- # [Go documentation](https://pkg.go.dev/path/filepath#Dir) for more details. This is analogous to
- # the POSIX `dirname` command.
- #
- # ```elvish-transcript
- # ~> path:dir /a/b/c/something
- # ▶ /a/b/c
- # ```
- #elvdoc:fn ext
- #
- # ```elvish
- # ext $path
- # ```
- #
- # Outputs the file name extension used by `$path` (including the separating period). If there is no
- # extension the empty string is output. See the [Go
- # documentation](https://pkg.go.dev/path/filepath#Ext) for more details.
- #
- # ```elvish-transcript
- # ~> path:ext hello.elv
- # ▶ .elv
- # ```
- #elvdoc:fn is-abs
- #
- # ```elvish
- # is-abs $path
- # ```
- #
- # Outputs `$true` if the path is an absolute path. Note that platforms like Windows have different
- # rules than UNIX like platforms for what constitutes an absolute path. See the [Go
- # documentation](https://pkg.go.dev/path/filepath#IsAbs) for more details.
- #
- # ```elvish-transcript
- # ~> path:is-abs hello.elv
- # ▶ false
- # ~> path:is-abs /hello.elv
- # ▶ true
- # ```
- #elvdoc:fn eval-symlinks
- #
- # ```elvish
- # eval-symlinks $path
- # ```
- #
- # Outputs `$path` after resolving any symbolic links. If `$path` is relative the result will be
- # relative to the current directory, unless one of the components is an absolute symbolic link.
- # This function calls `path:clean` on the result before outputting it. This is analogous to the
- # external `realpath` or `readlink` command found on many systems. See the [Go
- # documentation](https://pkg.go.dev/path/filepath#EvalSymlinks) for more details.
- #
- # ```elvish-transcript
- # ~> mkdir bin
- # ~> ln -s bin sbin
- # ~> path:eval-symlinks ./sbin/a_command
- # ▶ bin/a_command
- # ```
- #elvdoc:fn join
- #
- # ```elvish
- # path:join $path-component...
- # ```
- #
- # Joins any number of path elements into a single path, separating them with an
- # [OS specific separator](#path:separator). Empty elements are ignored. The
- # result is [cleaned](#path:clean). However, if the argument list is empty or
- # all its elements are empty, Join returns an empty string. On Windows, the
- # result will only be a UNC path if the first non-empty element is a UNC path.
- #
- # ```elvish-transcript
- # ~> path:join home user bin
- # ▶ home/user/bin
- # ~> path:join $path:separator home user bin
- # ▶ /home/user/bin
- # ```
- #elvdoc:fn is-dir
- #
- # ```elvish
- # is-dir &follow-symlink=$false $path
- # ```
- #
- # Outputs `$true` if the path resolves to a directory. If the final element of the path is a
- # symlink, even if it points to a directory, it still outputs `$false` since a symlink is not a
- # directory. Setting option `&follow-symlink` to true will cause the last element of the path, if
- # it is a symlink, to be resolved before doing the test.
- #
- # ```elvish-transcript
- # ~> touch not-a-dir
- # ~> path:is-dir not-a-dir
- # ▶ false
- # ~> path:is-dir /tmp
- # ▶ true
- # ```
- #
- # @cf path:is-regular
- #elvdoc:fn is-regular
- #
- # ```elvish
- # is-regular &follow-symlink=$false $path
- # ```
- #
- # Outputs `$true` if the path resolves to a regular file. If the final element of the path is a
- # symlink, even if it points to a regular file, it still outputs `$false` since a symlink is not a
- # regular file. Setting option `&follow-symlink` to true will cause the last element of the path,
- # if it is a symlink, to be resolved before doing the test.
- #
- # **Note:** This isn't named `is-file` because a UNIX file may be a "bag of bytes" or may be a
- # named pipe, device special file (e.g. `/dev/tty`), etc.
- #
- # ```elvish-transcript
- # ~> touch not-a-dir
- # ~> path:is-regular not-a-dir
- # ▶ true
- # ~> path:is-regular /tmp
- # ▶ false
- # ```
- #
- # @cf path:is-dir
- #elvdoc:fn temp-dir
- #
- # ```elvish
- # temp-dir &dir='' $pattern?
- # ```
- #
- # Creates a new directory and outputs its name.
- #
- # The &dir option determines where the directory will be created; if it is an
- # empty string (the default), a system-dependent directory suitable for storing
- # temporary files will be used. The `$pattern` argument determines the name of
- # the directory, where the last star will be replaced by a random string; it
- # defaults to `elvish-*`.
- #
- # It is the caller's responsibility to remove the directory if it is intended
- # to be temporary.
- #
- # ```elvish-transcript
- # ~> path:temp-dir
- # ▶ /tmp/elvish-RANDOMSTR
- # ~> path:temp-dir x-
- # ▶ /tmp/x-RANDOMSTR
- # ~> path:temp-dir 'x-*.y'
- # ▶ /tmp/x-RANDOMSTR.y
- # ~> path:temp-dir &dir=.
- # ▶ elvish-RANDOMSTR

- # ▶ /some/dir/elvish-RANDOMSTR
- # ```
- #elvdoc:fn temp-file
- #
- # ```elvish
- # temp-file &dir='' $pattern?
- # ```
- #
- # Creates a new file and outputs a [file](language.html#file) object opened
- # for reading and writing.
- #
- # The &dir option determines where the file will be created; if it is an
- # empty string (the default), a system-dependent directory suitable for storing
- # temporary files will be used. The `$pattern` argument determines the name of
- # the file, where the last star will be replaced by a random string; it
- # defaults to `elvish-*`.
- #
- # It is the caller's responsibility to close the file with
- # [`file:close`](file.html#file:close). The caller should also remove the file
- # if it is intended to be temporary (with `rm $f[name]`).
- #
- # ```elvish-transcript
- # ~> var f = (path:temp-file)
- # ~> put $f[name]
