Command wrapper for reporting the result. It is useful for cron jobs.

% go get github.com/Songmu/horenso/cmd/horenso

Built binaries are available on gihub releases. https://github.com/Songmu/horenso/releases

% horenso --reporter /path/to/report.pl -- /path/to/yourjob

Usage:
  horenso --reporter /path/to/reporter.pl -- /path/to/job [...]

Application Options:
  -r, --reporter=/path/to/reporter.pl     handler for reporting the result of the job
  -n, --noticer='ruby/path/to/noticer.rb' handler for noticing the start of the job
  -T, --timestamp                         add timestamp to merged output
  -t, --tag=job-name                      tag of the job

Handlers are should be an executable or command line string. You can specify multiple reporters and noticers. In this case, they are executed concurrently.

Normally you can use horenso with a wrapper shell script like following.

#!/bin/bash
/path/to/horenso \
  -n /path/to/noticer.py         \
  -r /path/to/reporter.pl        \
  -r 'ruby /path/to/reporter.rb' \
  -- "$@"

And specify this wrapper.sh in the crontab like following.

3 4 * * * /path/to/wrapper.sh /path/to/job --args...

If you want to change reporting way, you just have to change reporter script. You have no risk to crash wrapper shell.

1. Start the command
2. [optional] Run the noticers
3. Wait to finish the command
4. Run the reporters

The reporters and noticers are accept a result JSON via STDIN that reports command result like following.

    "perl",
