rsincron

Description

rsincron aims to be a drop-in replacement of the, it seems, abandoned incron projected.

You'll get two executables: 1. rsincrontab: use this to manage your table 2. rsincrond: the daemon itself. It isn't a daemon at the moment and I don't think I'll turn it into one. Use your favourite init system to manage it.

Usage

Please use rsincrontab -e to edit your rsincron's table. It discards invalid lines, while giving error feedback and keeps it formatted correctly.

rsincrontab format

It has the same format readable under EXAMPLE section in man incrontab.5. <path> <event_masks> <command to run>

Keep following in mind: - you can specify how many event masks you want separated by a single comma (,). Do not use whitespace. - flags (such as the only one implemented recursive=true) have to be added, comma separated, together with the masks - the rest gets parsed as the COMMAND to be run as bash -c "$COMMAND"

rsincrontab expansion

Following character combinations get expanded before being run: - $$ -> single $ - $@ -> path being watched - $# -> filename that triggered the event; '' if event is triggered by watched folder - $% -> triggered event masks as text - $& -> triggered event masks as bits

Installation

Cargo

Run cargo install rsincron.

Roadmap

• [ ] rsincrontab: incrontab's sibling

  • [ ] add flags for
    • [x] recursion
    • [ ] dotdirs
  • [ ] add more verbose output

• [ ] rsincrond: the daemon itself

  • [x] instantiate logging (somewhere has to be written which watches are working and which aren't)
  • [x] build some sort of same flag watch if a directory is made inside a watched one (with recursion on)

• [ ] write every single type of test

• [ ] cleanup and reorganize code to allow more modularity
• [ ] write documentation

Currently working on

Some sort of runtime checks: - [x] loop checks for missed folders, if recursion is on, and adds them to the active watches - [x] general, configurable, logging (now it's very minimal to stdin/stderr) - [ ] loop checks for removed folders (if active watch is now looking nowhere move it to FailedWatches) - [ ] better debug and info logging

About

This is a very not ready piece of software. Be ready for things not working as expected.

I don't have an ETA yet since rsincron will be worked on during my spare time. Feel free to message me for suggestions, critiques, hints or contribution questions.

Also, I neved had a public repository. If you want to share some experience on how to maintain one feel welcome to do so.

Please expect lots of bugs, rsincron isn't alpha yet. It looks closer to a proof-of-concept at the moment.

Known issues

• [ ] daemon ignores events if watched folder is deleted and recreated while running
• [x] no recursion is available at the moment
• [x] if started and watched folder isn't available daemon skips watch
