Add "path" builtin This adds a "path" builtin that can handle paths. Implemented so far: - "path filter PATHS", filters paths according to existence and optionally type and permissions - "path base" and "path dir", run basename and dirname, respectively - "path extension PATHS", prints the extension, if any - "path strip-extension", prints the path without the extension - "path normalize PATHS", normalizes paths - removing "/./" components - and such. - "path real", does realpath - i.e. normalizing *and* link resolution. Some of these - base, dir, {strip-,}extension and normalize operate on the paths only as strings, so they handle nonexistent paths. filter and real ignore any nonexistent paths. All output is split explicitly, so paths with newlines in them are handled correctly. Alternatively, all subcommands have a "--null-input"/"-z" and "--null-output"/"-Z" option to handle null-terminated input and create null-terminated output. So find . -print0 | path base -z prints the basename of all files in the current directory, recursively. With "-Z" it also prints it null-separated. (if stdout is going to a command substitution, we probably want to skip this) All subcommands also have a "-q"/"--quiet" flag that tells them to skip output. They return true "when something happened". For match/filter that's when a file passed, for "base"/"dir"/"extension"/"strip-extension" that's when something about the path *changed*. Filtering --------- `filter` supports all the file*types* `test` has - "dir", "file", "link", "block"..., as well as the permissions - "read", "write", "exec" and things like "suid". It is missing the tty check and the check for the file being non-empty. The former is best done via `isatty`, the latter I don't think I've ever seen used. There currently is no way to only get "real" files, i.e. ignore links pointing to files. Examples -------- > path real /bin///sh /usr/bin/bash > path extension foo.mp4 mp4 > path extension ~/.config (nothing, because ".config" isn't an extension.)

#RUN: %fish %s
# The "path" builtin for dealing with paths
# Extension - for figuring out the file extension of a given path.
path extension /
or echo None
extension: Print empty entry if there is no extension Because we now count the extension including the ".", we print an empty entry. This makes e.g. ```fish set -l base (path change-extension '' $somefile) set -l ext (path extension $somefile) echo $base$ext ``` reconstruct the filename, and makes it easier to deal with files with no extension.

Add "path" builtin This adds a "path" builtin that can handle paths. Implemented so far: - "path filter PATHS", filters paths according to existence and optionally type and permissions - "path base" and "path dir", run basename and dirname, respectively - "path extension PATHS", prints the extension, if any - "path strip-extension", prints the path without the extension - "path normalize PATHS", normalizes paths - removing "/./" components - and such. - "path real", does realpath - i.e. normalizing *and* link resolution. Some of these - base, dir, {strip-,}extension and normalize operate on the paths only as strings, so they handle nonexistent paths. filter and real ignore any nonexistent paths. All output is split explicitly, so paths with newlines in them are handled correctly. Alternatively, all subcommands have a "--null-input"/"-z" and "--null-output"/"-Z" option to handle null-terminated input and create null-terminated output. So find . -print0 | path base -z prints the basename of all files in the current directory, recursively. With "-Z" it also prints it null-separated. (if stdout is going to a command substitution, we probably want to skip this) All subcommands also have a "-q"/"--quiet" flag that tells them to skip output. They return true "when something happened". For match/filter that's when a file passed, for "base"/"dir"/"extension"/"strip-extension" that's when something about the path *changed*. Filtering --------- `filter` supports all the file*types* `test` has - "dir", "file", "link", "block"..., as well as the permissions - "read", "write", "exec" and things like "suid". It is missing the tty check and the check for the file being non-empty. The former is best done via `isatty`, the latter I don't think I've ever seen used. There currently is no way to only get "real" files, i.e. ignore links pointing to files. Examples -------- > path real /bin///sh /usr/bin/bash > path extension foo.mp4 mp4 > path extension ~/.config (nothing, because ".config" isn't an extension.)

normalize: Add "./" if a path starts with a "-"

# Paths with "-" get a "./":
path normalize -- -/foo -foo/foo
# CHECK: ./-/foo
# CHECK: ./-foo/foo
path normalize -- ../-foo
# CHECK: ../-foo
Also prepend "./" for filter if a filename starts with "-" This is now added to the two commands that definitely deal with relative paths. It doesn't work for e.g. `path basename`, because after removing the dirname prepending a "./" doesn't refer to the same file, and the basename is also expected to not contain any slashes.

Add "path" builtin This adds a "path" builtin that can handle paths. Implemented so far: - "path filter PATHS", filters paths according to existence and optionally type and permissions - "path base" and "path dir", run basename and dirname, respectively - "path extension PATHS", prints the extension, if any - "path strip-extension", prints the path without the extension - "path normalize PATHS", normalizes paths - removing "/./" components - and such. - "path real", does realpath - i.e. normalizing *and* link resolution. Some of these - base, dir, {strip-,}extension and normalize operate on the paths only as strings, so they handle nonexistent paths. filter and real ignore any nonexistent paths. All output is split explicitly, so paths with newlines in them are handled correctly. Alternatively, all subcommands have a "--null-input"/"-z" and "--null-output"/"-Z" option to handle null-terminated input and create null-terminated output. So find . -print0 | path base -z prints the basename of all files in the current directory, recursively. With "-Z" it also prints it null-separated. (if stdout is going to a command substitution, we probably want to skip this) All subcommands also have a "-q"/"--quiet" flag that tells them to skip output. They return true "when something happened". For match/filter that's when a file passed, for "base"/"dir"/"extension"/"strip-extension" that's when something about the path *changed*. Filtering --------- `filter` supports all the file*types* `test` has - "dir", "file", "link", "block"..., as well as the permissions - "read", "write", "exec" and things like "suid". It is missing the tty check and the check for the file being non-empty. The former is best done via `isatty`, the latter I don't think I've ever seen used. There currently is no way to only get "real" files, i.e. ignore links pointing to files. Examples -------- > path real /bin///sh /usr/bin/bash > path extension foo.mp4 mp4 > path extension ~/.config (nothing, because ".config" isn't an extension.)

path: Make path real "work" with nonexistent paths This just goes back until it finds an existent path, resolves that, and adds the normalized rest on top. So if you try /bin/foo/bar////../baz and /bin exists as a symlink to /usr/bin, it would resolve that, and normalize the rest, giving /usr/bin/foo/baz (note: We might want to add this to realpath as well?)

resolve: Normalize This means "../" components are cancelled out even after non-existent paths or files. (the alternative is to error out, but being able to say `path resolve /path/to/file/../../` over `path resolve (path dirname /path/to/file)/../../` seems worth it?)
