Command-T in emacs

Question

Is there something similar to the CommandT plugin in vim for emacs? I know some plugins that do directory-based completion, but is there one that does matching on the full paths?

An example:

├── bar
│   └── hello
├── baz
│   └── test
│       └── hello
└── foo
    ├── hello
    └── lost

baz
baz/test
baz/test/hello
bar
bar/hello
foo
foo/hello
foo/lost

Now when I type 'h', I'd like the paths

baz/test/hello
bar/hello
foo/hello

to match. For 't', there should be

baz/test/hello
foo/lost

Answer 1

ido does this AFAIK, and also anything.el.

Also, this emacswiki page has a list packages which do something similar.

Edit: According to Drew's comment Ido does not match the whole path. Anything on the other hand does, as it can be seen on the screenshot behind the link.

Answer 2

Icicles does matching on full paths (i.e., any and all parts of an absolute file name). See Icicles File-Name Input.

By default, in Icicle mode C-x C-f is bound to icicle-file:

• without a prefix arg -- uses the usual Emacs relative file-name completion

• with a prefix arg (e.g. C-u C-x C-f) -- does absolute file-name completion

Command icicle-find-file-absolute is the same as C-u C-x C-f. You can bind it if you don't want to use the key sequence C-u C-x C-f each time.

During completion of either type (relative/absolute file names), you can use any of the Icicles completion features, such as:

• progressive completion (match name parts in any order)
• candidate help
• candidate cycling
• candidate sorting
• fuzzy completion (the Vim screencast you cite uses the equivalent of Icicles "scatter" matching and Ido "flex" matching)

And file-name completion commands such as these are multi-commands, which means you can act on multiple files with the same command. See also command icicle-locate, which does absolute file-name matching and lets you find and act on files anywhere on your file system, without knowing their locations.
