dotcfg

A small and fast configuration daemon for use with my dotfiles

build & requirements

• libc (POSIX-compatible, with unix domain sockets)
• zig 0.13.0

To build:

zig build

usage

Usage example:

dotcfg daemon &
dotcfg send 'set:bemenu.font:Mononoki Normal 15'
dotcfg send 'get:bemenu.font' # Mononoki Normal 15

dotcfg stdin-send <<EOF
set:dummy:aargh
get:dummy
EOF
# will output "aargh"

Here is an excerpt from the output of dotcfg help:

Usage: dotcfg { daemon | send [MESSAGES...] | stdin-send | help }

COMMANDS

  daemon: starts the daemon, taking into account the DOTCFG_SOCKET path.

  send: send one message per argument

  stdin-send: same as send, but instead of one command per argument it is one
  command per line

  help: show this message

MESSAGES

  To communicate with the daemon, the client uses messages, which are one-line strings with commands. They can
  be of the following types:

    set:<KEY>:<VALUE> to set a property
    get:<KEY> to get a property's value

    Characters not allowed for the key: ':', '\n'
    Characters not allowed for the value: '\n'

  Upon dealing with these commands, you can receive responses. The response for successful operations is
  simply a line containing the option's value.

  The following responses are error responses:

    err:missing-command
    err:missing-key
    err:unknown-command
    err:read-error

  After outputting all responses, if at least one of them is an error, the program returns 1. If an invalid
  response is detected, though, the program exits 1 immediately.

to do

• split the code into smaller files and structs

• use the standard library for most things instead of directly using C headers

• upgrade to zig 0.13.0

• automated testing
