## `$ flake-edit` - usage
`flake-edit` has the following cli interface:
```
Edit your flake inputs with ease.
Usage: flake-edit [OPTIONS] <COMMAND>
Commands:

Manually add a single follows declaration
config

help
Print this message or the help of the given subcommand(s)
Options:
--flake <FLAKE>
Location of the `flake.nix` file, that will be used. Defaults to `flake.nix` in the current directory
--lock-file <LOCK_FILE>
Location of the `flake.lock` file. Defaults to `flake.lock` in the current directory

Print a diff of the changes, will not write the changes to disk
--no-lock
Skip updating the lockfile after editing flake.nix
--non-interactive

```
### `$ flake-edit add`
```
Add a new flake reference
Usage: flake-edit add [OPTIONS] [ID] [URI]
Arguments:
[ID]
The name of an input attribute
[URI]
The uri that should be added to the input
Options:
--ref-or-rev <REF_OR_REV>
Pin to a specific ref_or_rev
-n, --no-flake
The input itself is not a flake
-s, --shallow
Use shallow clone for the input
-h, --help
Print help
```
For some types, the id will be automatically inferred.
For some inputs, the uri can be put in directly and the id and type will be inferred.
### `$ flake-edit remove`
```
Remove a specific flake reference based on its id
Usage: flake-edit remove [ID]
Arguments:
[ID]
Options:
-h, --help
Print help
```
### `$ flake-edit update`
```
Update inputs to their latest specified release
Usage: flake-edit update [OPTIONS] [ID]
Arguments:
[ID]
The id of an input attribute. If omitted will update all inputs
Options:
--init
Whether the latest semver release of the remote should be used even thought the release itself isn't yet pinned to a specific release
-h, --help
Print help
```
### `$ flake-edit change`
```
Change an existing flake reference's URI
Usage: flake-edit change [OPTIONS] [ID] [URI]
Arguments:
[ID]
The name of an existing input attribute
[URI]
The new URI for the input
Options:
--ref-or-rev <REF_OR_REV>
Pin to a specific ref_or_rev
-s, --shallow
Use shallow clone for the input
-h, --help
Print help
```
### `$ flake-edit pin`
```
Pin inputs to their current or a specified rev
Usage: flake-edit pin [ID] [REV]
Arguments:
[ID]
The id of an input attribute
[REV]
Optionally specify a rev for the inputs attribute
Options:
-h, --help
Print help
```
Pin a specific input to it's current revision (rev).
### `$ flake-edit unpin`
```
Unpin an input so it tracks the upstream default again
Usage: flake-edit unpin [ID]
Arguments:
[ID]
The id of an input attribute
Options:
-h, --help
Print help
```
### `$ flake-edit list`
```
List flake inputs
Usage: flake-edit list [OPTIONS]
Options:
--format <FORMAT>
[default: detailed]
-h, --help
Print help
```
List the outputs, that are specified inside the inputs attribute.
List the outputs, that are specified inside the inputs attribute, in json format.
### `$ flake-edit follow`
```
Automatically add and remove follows declarations.
Analyzes the flake.lock to find nested inputs that match top-level inputs, then adds appropriate follows declarations and removes stale ones.
With file paths, processes multiple flakes in batch. For every `flake.nix` file passed in it will assume a `flake.lock` file exists in the same directory.
Usage: flake-edit follow [PATHS]...
Arguments:
[PATHS]...
Flake.nix paths to process. If empty, runs on current directory
Options:
-h, --help
Print help (see a summary with '-h')
```
Automatically add follows relationships for all nested inputs matching top-level inputs.
### `$ flake-edit add-follow`
```
Manually add a single follows declaration.
Example: `flake-edit add-follow rust-overlay.nixpkgs nixpkgs`
This creates: `rust-overlay.inputs.nixpkgs.follows = "nixpkgs";`
Without arguments, starts an interactive selection.
Usage: flake-edit add-follow [INPUT] [TARGET]
Arguments:
[INPUT]
The input path in dot notation (e.g., "rust-overlay.nixpkgs" means the nixpkgs input of rust-overlay)
[TARGET]
The target input to follow (e.g., "nixpkgs")
Options:
-h, --help
Print help (see a summary with '-h')
```
Add a follows relationship to a specific nested input.
### `$ flake-edit config`
```
Manage flake-edit configuration
Usage: flake-edit config [OPTIONS]
Options:
--print-default
Output the default configuration to stdout
--path
Show where configuration would be loaded from
-h, --help
Print help
```
## Quick Start
### Installation
```
cargo install flake-edit --locked
```
### Running
From `nixpkgs`:
```
nix run nixpkgs#flake-edit -- --diff follow
```
From `main` of `flake-edit`:
```
nix run github:a-kenji/flake-edit -- --diff follow
```
### Basic Usage
Add a new input to your flake:
```
flake-edit add github:numtide/treefmt-nix
```
Auto-follow all your inputs through `flake.nix`:
```
flake-edit follow
```
Add `--diff` to any command to get a preview of the changes:
```
flake-edit --diff follow
```
## Configuration
`flake-edit` uses TOML configuration files.
Run `flake-edit config --print-default` to create a default configuration:
```
# flake-edit ~ configuration file
# https://github.com/a-kenji/flake-edit
# Configuration for `flake-edit follow [PATHS]`
[follow.auto]
# Inputs to ignore. Supports two formats:
# - Full path: "crane.nixpkgs" - ignores only that specific nested input
# - Simple name: "systems" - ignores all nested inputs with that name
# ignore = ["systems", "crane.flake-utils"]
# Alias mappings.
# Key is the canonical name (must exist at top-level), values are alternatives.
# Example: if nested input is "nixpkgs-lib" and top-level "nixpkgs" exists,
# auto-follow will suggest: poetry2nix.nixpkgs-lib -> nixpkgs
# aliases = { nixpkgs = ["nixpkgs-lib"] }
```
## As a library
Add `flake-edit` as a library by running:
```
cargo add flake-edit --no-default-features
```
Be aware that the `lib` interface is still unstable.
Though we are already happy to get feedback.
## Status
> [!NOTE]
> This project is currently in active development and should be considered a work in progress.
> The goal of `flake-edit` is to provide a robust and well-tested interface to flake inputs.
> Many edge cases are not covered yet, if you find any issues please consider opening an issue, or a pr.
> And we would be happy for feedback of the cli interface especially.
