View Source Igniter (igniter v0.3.25)
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
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.
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
Updates the source code of the given elixir file
Updates a given file's Rewrite.Source
Updates all files matching the given glob with the given zipper function.
Types
@type zipper_updater() :: (Sourceror.Zipper.t() -> {:ok, Sourceror.Zipper.t()} | {:error, String.t() | [String.t()]})
Functions

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.
Returns the remaining changes in the Igniter if successful.
Options
:error_on_abort?- Iftrue, raises an error if the user aborts the operation. Returns the original igniter if not.:yes- Iftrue, automatically applies the changes without prompting the user.
Stores the key/value pair in igniter.assigns
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.
@spec copy_template( igniter :: t(), target :: Path.t(), source :: Path.t(), assigns :: Keyword.t(), opts :: Keyword.t() ) :: t()
Copies an EEx template file from the source path to the target path.
Accepts the same options as create_new_file/4.
Creates a new file in the project with the provided string contents. Adds an error if it already exists.
Options
:on_exists- The action to take if the file already exists. Can be:error(default) - Adds an error that prevents any eventual write.:warning- Warns when writing but continues (without overwriting):skip- Skips writing the file without a warning:overwrite- Warns when writing and overwrites the content with the new content
@spec create_or_update_elixir_file(t(), Path.t(), String.t(), zipper_updater()) :: t()
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.
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.
@spec new() :: t()
Returns a new igniter
@spec update_elixir_file(t(), Path.t(), zipper_updater()) :: t()
Updates the source code of the given elixir file
Updates a given file's Rewrite.Source
@spec update_glob( t(), Path.t() | GlobEx.t(), zipper_updater() ) :: t()
Updates all files matching the given glob with the given zipper function.
Adds any new files matching that glob to the igniter first.
