embulk-input-command

Command file input plugin for Embulk: runs a command and reads data from its stdout (or stderr).

Overview

• Plugin type: file input
• Resume supported: yes (no parallelism)

Configuration

• command: command line (string, required)
• pipe: stdout or stderr (string, default: stdout)

The command is exected using a shell (sh -c on UNIX/Linux, PowerShell.exe -Command on Windows). Therefore, it can include pipe (|), environment variables ($VAR), redirects, and so on.

Example

in:
  type: command
  command: echo "a,c,c" && echo "1,2,3" && echo "10,11,12" | grep -v 10

For Maintainers

Release

Modify version in build.gradle at a detached commit, and then tag the commit with an annotation.

git checkout --detach master

(Edit: Remove "-SNAPSHOT" in "version" in build.gradle.)

git add build.gradle

git commit -m "Release vX.Y.Z"

git tag -a vX.Y.Z

(Edit: Write a tag annotation in the changelog format.)

See Keep a Changelog for the changelog format. We adopt a part of it for Git's tag annotation like below.

## [X.Y.Z] - YYYY-MM-DD

### Added
- Added a feature.

### Changed
- Changed something.

### Fixed

Push the annotated tag, then. It triggers a release operation on GitHub Actions after approval.

git push -u origin vX.Y.Z
