Task context - Aspect Build docs

function TaskContext.defer

def TaskContext.defer(
callable: typing.Any,
/,
*args: typing.Any,
**kwargs: typing.Any
) -> None

Register a callable to run after _impl returns, modeled on Go’s defer: args bound at the defer site, LIFO order, fires even when _impl aborts. Per-defer errors are logged and do not change the task’s exit code. function TaskContext.http

def TaskContext.http() -> Http

HTTP client for issuing requests to remote services. property TaskContext.args

TaskContext.args: Arguments

Resolved arguments for this task invocation. Read individual values as ctx.args.<arg_name>. Values are produced by merging, in order of decreasing precedence: explicit CLI flags, config.axl overrides, and the task’s declared arg defaults. property TaskContext.aspect

TaskContext.aspect: aspect.Aspect

Aspect platform integrations — authentication and other hosted services provided by the Aspect Workflows backend. property TaskContext.bazel

TaskContext.bazel: bazel.Bazel

Drive Bazel from a task: run build, test, query, info, parse .bazelrc, and consume Build Event Stream output. property TaskContext.std

TaskContext.std: std.Std

The standard library. Gives access to common utilities such as filesystem, process execution, environment variables, and IO streams. property TaskContext.task

TaskContext.task: TaskInfo

Identity of the currently running task — its name, group(s), short human-readable key, and globally unique id. property TaskContext.template

TaskContext.template: Template

Render template files by substituting placeholders with values. property TaskContext.traits

TaskContext.traits: TraitMap

Configured trait instances visible to this task. Index by a trait type to read its fields, e.g. ctx.traits[GitHub].token. Only trait types this task opted into via task(traits = [...]) are present. property TaskContext.wasm

TaskContext.wasm: wasm.Wasm

Execute WebAssembly modules within a task. EXPERIMENTAL: this surface may change or be removed without notice.
