matchmaker-cli-0.0.11 is not a library.

Matchmaker

Matchmaker is fast, configurable and intuitive fuzzy searcher.

It takes inspiration from fzf in features and design, but reimagines the user experience. Built from the ground up in Rust using modern libraries, it provides a maximally cohesive, performant and versatile experience, in a minimal amount of code. It's simple to get started, give it a try! [^10]

Features

Matching with nucleo.
Fully configurable via a type-checked toml file. [^11]
A minimal yet powerful syntax for overriding the configuration on the command line.
Interactive preview supports color, scrolling, wrapping, multiple layouts, and even maximizing.
Most of the familiar actions from fzf, as well as several new ones[^12].
Mouse (location aware) scrolling! Horizontal scrolling! Grapheme-aware input wrapping!
Split input lines into multiple columns, that you can individually filter on (using the syntax: %col query), hide, and highlight.[^14]
Define Execute/Preview/Print/Accept actions based on the current item using Templating (yes, columns are supported here too).
All the dynamic UI support you could hope for: preview offsets, styled status lines, responsive header tables, wrapped footers, active and inactive column colors, stacked columns, multiple preview layouts[^15]... even overlays! (in the library).
Bind keys to multiple actions, bind actions to mouse triggers, bind actions to event triggers, bind keys to rebind keys, bind keys to modify the configuration, bind keys to run a shell script and use its output to more keys[^16], bind keys to set the header, footer, status, input, bind keys to semantic triggers, bind semantic triggers to actions, bind keys to -- wait nope thats about it.
oh yeah, and mm --last-key gives you the last key that was pressed in a previous run of the program.[^13]
Available as a rust library to use in your own code!

On the way:

Matching with frizbee, a faster, typo-resistant matching algorithm.

[^10]: Sample configurations are on the roadmap, and contributions are very welcome!

[^11]: The benefits of a structured, hierarchical, global baseline configuration are many, including but not limited to the fact that toml strings make it much easier to bind keys to complex shell scripts.

[^12]: Custom exit codes, select all (CycleAll), PageUp/Down, Show Help, Cycle columns (NextColumn), Multiple input commands (NextReload), etc. ...

[^13]: This is useful for when you want to write a shell script that dispatches different actions on the output of matchmaker based on the key that was pressed.

[^14]: If no column names are configured, the autogenerated column names are sequential: 1, 2, 3...

[^15]: I like this so much i had to mention it twice

[^16]: you can't do this yet

Installation

cargo install matchmaker-cli

# or grab a release from the releases page with bonus features.

Pass it some items:

find . | mm

[!NOTE] The default input and preview commands rely on fd, bat and eza. For an optimal experience, install them or update your configuration.

Configuration

To begin, you can dump the default configuration to a file:

matchmaker --dump-config

The default locations are in order:

~/.config/matchmaker/config.toml (If the folder exists already).
{PLATFORM_SPECIFIC_CONFIG_DIRECTORY}/matchmaker (Generally the same as above when on linux)

Matchmaker options are hierarchical, although most categories live at the top level:

[preview]
    show = true
    wrap = true
    header_lines = 3 # sticky the top 3 lines

# Full specification of (the default values of) a single layout. Multiple layouts can be specified.
[[preview.layout]]
    command    = ""
    side       = "right"
    percentage = 60
    min        = 30
    max        = 120

The structure of the config file is defined here[^1], and the full specification lives here[^2].

Options can be overridden on the command line, where abbreviations are supported:

mm --config ~/.config/matchmaker/alternate.toml p.l "cmd=[echo {}] p=50 max=20" cmd "ls" o "'{}'"

# 1. Start mm with an alternate config, as well as with the following overrides:
# 2. List the contents of the current directory by executing `ls`
# 3. Show the current item name in the preview pane
# 4. Set a preferred percentage of 50 for the preview pane, and a maximum column width of 20 for the preview pane
# 5. Output the result wrapped in single quotes

[^1]: Note that the flatten attribute on the render field means that the subfields of RenderConfig should be specified at the top level of the toml (i.e. your toml should specify [results] instead of [render.results]).

[^2]: and parts of it here.

Keybindings

Actions can be defined in your config.toml or on the command line.

The list of currently supported actions can be found here and here or from mm --options.

To get the names of keys, type mm --test-keys.

In addition to keys, actions can also be bound to Events and Crossterm events (check your default config for details).

CLI

See here for the command-line syntax.

Matchmaker aims to achieve feature-parity with fzf (though not necessarily by the same means). If there's any specific feature that you'd like to see, open an issue!

Library

Matchmaker can also be used as a library.

cargo add matchmaker

Example

Here is how to use Matchmaker to select from a list of strings.

use matchmaker::nucleo::{Indexed, Worker};
use matchmaker::{MatchError, Matchmaker, Result, Selector};

#[tokio::main]
async fn main() -> Result<()> {
    let items = vec!["item1", "item2", "item3"];

    let worker = Worker::new_single_column();
    worker.append(items);
    let selector = Selector::new(Indexed::identifier);
    let mm = Matchmaker::new(worker, selector);

    match mm.pick_default().await {
        Ok(v) => {
            println!("{}", v[0]);
        }
        Err(err) => match err {
            MatchError::Abort(1) => {
                eprintln!("cancelled");
            }
            _ => {
                eprintln!("Error: {err}");
            }
        },
    }

    Ok(())
}
