# Filesets
|
|
|
|
|
|
|
|
|
|
Jujutsu supports a functional language for selecting a set of files.
|
|
|
|
|
Expressions in this language are called "filesets" (the idea comes from
|
|
|
|
|
[Mercurial](https://repo.mercurial-scm.org/hg/help/filesets)). The language

|
|
|
consists of file patterns, operators, and functions.

## File patterns
|
|
|
|
|
|
|
|
|
|
The following patterns are supported:
|
|
|
|
|
|
|
|
|
|
* `"path"`, `path` (the quotes are optional), or `cwd:"path"`: Matches
|
|
|
|
|
cwd-relative path prefix (file or files under directory recursively.)
|
|
|
|
|
* `cwd-file:"path"` or `file:"path"`: Matches cwd-relative file (or exact) path.
|
|
|
|
|
* `root:"path"`: Matches workspace-relative path prefix (file or files under
|
|
|
|
|
directory recursively.)
|
|
|
|
|
* `root-file:"path"`: Matches workspace-relative file (or exact) path.

|
|
|
## Operators
|
|
|
|
|
|
|
|
|
|
The following operators are supported. `x` and `y` below can be any fileset
|
|
|
|
|
expressions.
|
|
|
|
|
|
|
|
|
|
* `x & y`: Matches both `x` and `y`.
|
|
|
|
|
* `x | y`: Matches either `x` or `y` (or both).
|
|
|
|
|
* `x ~ y`: Matches `x` but not `y`.
|
|
|
|
|
* `~x`: Matches everything but `x`.
|
|
|
|
|
|
|
|
|
|
You can use parentheses to control evaluation order, such as `(x & y) | z` or
|
|
|
|
|
`x & (y | z)`.
|
|
|
|
|
|
|
|
|
|
## Functions
|
|
|
|
|
|
|
|
|
|
You can also specify patterns by using functions.
|
|
|
|
|
|
|
|
|
|
* `all()`: Matches everything.
|
|
|
|
|
* `none()`: Matches nothing.
