View Source Igniter (igniter v0.3.67)

Tools for generating and patching code into an Elixir project.

Summary

Functions

Adds an issue to the issues list. Any issues will prevent writing and be displayed to the user.

Adds a notice to the notices list. Notices are displayed to the user once the igniter finishes running.

Adds a task to the tasks list. Tasks will be run after all changes have been commited

Adds a warning to the warnings list. Warnings will not prevent writing, but will be displayed to the user.

Applies the current changes to the mix.exs in the Igniter and fetches dependencies.

Stores the key/value pair in igniter.assigns

Returns true if the igniter or source provided has changed

Returns true if any of the files specified in paths have changed.

Finds the Igniter.Mix.Task task by name and composes it (calls its igniter/2) into the current igniter. If the task doesn't exist, a fallback implementation may be provided as the last argument.

Copies an EEx template file from the source path to the target path.

Creates a new file in the project with the provided string contents. Adds an error if it already exists.

Creates the given file in the project with the provided string contents, or updates it with a function of type zipper_updater() if it already exists.

Creates the given file in the project with the provided string contents, or updates it with a function as in update_file/3 (or with zipper_updater() for elixir files) if it already exists.

Executes or dry-runs a given Igniter.

Checks if a file exists on the file system or in the igniter.

Returns whether the current Igniter has pending changes.

This function stores in the igniter if its been run before, so it is only run once, which is expensive.

Includes the given file in the project, expecting it to exist. Does nothing if its already been added.

Includes all files matching the given glob, expecting them all (for now) to be elixir files.

Includes or creates the given file in the project with the provided contents. Does nothing if its already been added.

Returns a new igniter

Runs an update over all elixir files

Updates the source code of the given elixir file

Updates all files matching the given glob with the given zipper function.

compose_task(igniter, task, argv \\ [], fallback \\ nil)

View Source

Finds the Igniter.Mix.Task task by name and composes it (calls its igniter/2) into the current igniter. If the task doesn't exist, a fallback implementation may be provided as the last argument.
