Temper.History.Template (temper v0.2.1)

Copy Markdown View Source

The {partition} placeholder in configured history paths.

A custom :history_path containing {partition} is partition-safe by construction: the formatter expands the placeholder with the current MIX_TEST_PARTITION value before writing, and the report and clean tasks widen it to * so a read covers every partition's file — the same behavior the default .temper/history-{partition}.jsonl location has always had.

A path without the placeholder passes through both functions unchanged.

Summary

Functions

expand(path, partition)

Expands {partition} with the partition value for writing.

to_glob(path)

Widens {partition} to * so one glob reads every partition's file.

Functions

expand(path, partition)

@spec expand(Path.t(), String.t() | nil) :: Path.t()

Expands {partition} with the partition value for writing.

A nil partition (no MIX_TEST_PARTITION set) maps to "0", mirroring Temper.History.Writer.default_path/1.

to_glob(path)

@spec to_glob(Path.t()) :: Path.t()

Widens {partition} to * so one glob reads every partition's file.
