@ember-template-lint/todo-utils
A collection of utilities to generate and store lint item metadata.
Those utilities are:
Functions
- buildTodoDatum(lintResult, lintMessage, todoConfig) ⇒
Adapts a LintResult to a TodoData. FilePaths are absolute when received from a lint result, so they're converted to relative paths for stability in serializing the contents to disc.
- todoStorageFileExists(baseDir) ⇒
Determines if the .lint-todo storage file exists.
- ensureTodoStorageFile(baseDir) ⇒
Creates, or ensures the creation of, the .lint-todo file.
- getTodoStorageFilePath(baseDir) ⇒
- hasConflicts(todoContents) ⇒
Determines if the .lint-todo storage file has conflicts.
- resolveConflicts(operations) ⇒
Resolves git conflicts in todo operations by removing any lines that match conflict markers.
- readTodoStorageFile(todoStorageFilePath) ⇒
Reads the .lint-todo storage file.
- writeTodoStorageFile(todoStorageFilePath, operations)
Writes the operations to the .lint-todo storage file to the path provided by todoStorageFilePath.
- writeTodos(baseDir, maybeTodos, options) ⇒
Writes files for todo lint violations. One file is generated for each violation, using a generated hash to identify each.
Given a list of todo lint violations, this function will also delete existing files that no longer have a todo lint violation.
- readTodos(baseDir, shouldLock) ⇒
Reads all todo files in the .lint-todo directory.
- readTodosForFilePath(todoStorageDir, filePath, shouldLock) ⇒
Reads todo files in the .lint-todo directory for a specific filePath.
- readTodoData(baseDir) ⇒
Reads todo files in the .lint-todo directory and returns Todo data in an array.
- getTodoBatches(maybeTodos, existing, options) ⇒
Gets 4 maps containing todo items to add, remove, those that are expired, or those that are stable (not to be modified).
- applyTodoChanges(baseDir, add, remove, shouldLock)
Applies todo changes, either adding or removing, based on batches from
getTodoBatches.- ADD_OPERATIONS_ONLY(operation) ⇒
Compact strategy to leave only add operations in the todo storage file.
- EXCLUDE_EXPIRED(operation) ⇒
Compact strategy to remove all expired operations from the todo storage file.
- compactTodoStorageFile(baseDir, compactStrategy) ⇒
Compacts the .lint-todo storage file based on the compact strategy.
- getTodoConfig(baseDir, engine, customDaysToDecay) ⇒
Gets the todo configuration. Config values can be present in
The package.json
- validateConfig(baseDir) ⇒
Validates whether we have a unique config in a single location.
- getSeverity(todo, today) ⇒
Returns the correct severity level based on the todo data's decay dates.
- isExpired(date, today) ⇒
Evaluates whether a date is expired (earlier than today)
- getDatePart(date) ⇒
Converts a date to include year, month, and day values only (time is zeroed out).
- differenceInDays(startDate, endDate) ⇒
Returns the difference in days between two dates.
- format(date) ⇒
Formats the date in short form, eg. 2021-01-01
