Cross-platform Terminal Manipulation Library
Crossterm is a pure-rust, terminal manipulation library that makes it possible to write cross-platform text-based interfaces (see features). It supports all UNIX and Windows terminals down to Windows 7 (not all terminals are tested, see Tested Terminals for more info).

This crate supports all UNIX terminals and Windows terminals down to Windows 7; however, not all of the terminals have been tested. If you have used this library for a terminal other than the above list without issues, then feel free to add it to the above list - I really would appreciate it!

Feature Flags
[dependencies.crossterm]
version = "0.27"
features = ["event-stream"]
| Feature | Description |
|---|---|
event-stream |
futures::Stream producing Result<Event>. |
serde |
(De)serializing of events. |
events |
Reading input/system events (enabled by default) |
filedescriptor |
Use raw filedescriptor for all events rather then mio dependency |
derive-more |
Adds is_* helper functions for event types |
osc52 |
Enables crossterm::clipboard |
To use crossterm as a very thin layer you can disable the events feature or use filedescriptor feature.
This can disable mio / signal-hook / signal-hook-mio dependencies.
Dependency Justification
| Dependency | Used for | Included |
|---|---|---|
bitflags |
KeyModifiers, those are differ based on input. |
always |
parking_lot |
locking RwLocks with a timeout, const mutexes. |
always |
libc |
UNIX terminal_size/raw modes/set_title and several other low level functionality. | optional (events feature), UNIX only |
Mio |
event readiness polling, waking up poller | optional (events feature), UNIX only |
signal-hook |
signal-hook is used to handle terminal resize SIGNAL with Mio. | optional (events feature),UNIX only |
winapi |
Used for low-level windows system calls which ANSI codes can't replace | windows only |
futures-core |
For async stream of events | only with event-stream feature flag |
serde |
serializing and deserializing of events | only with serde feature flag |
derive_more |
Adds is_* helper functions for event types |
optional (derive-more feature), included by default |
base64 |
Encoding clipboard data for OSC52 sequences in crossterm::clipboard | only with osc52 feature flag |
