r[un concurrent]ly
rly
is a concurrent task runner and, in its current form, essentially a clone of concurrently. For example:
$ rly --names "server,client" \
--kill-others \
"nc -lk 1234" \
"echo 'message from client' | nc localhost 1234"
[server] message from client
[client] echo 'message from client' | nc localhost 1234 exited with exit status: 0
--> Sending SIGKILL to other processes..
[server] nc -lk 1234 exited with signal: 9 (SIGKILL)
Installation
Currently you need to have rust installed in order to install rly
:
cargo install rly
Usage (in progress)
Usage: rly [OPTIONS] [COMMANDS]...
Arguments:
[COMMANDS]...
Options:
-n, --names <NAMES>
List of custom names to be used in prefix template.
Example names: "main,browser,server"
--name-separator <NAME_SEPARATOR>
The character to split <names> on.
Example usage: -n "styles|scripts|server" --name-separator
"|"
[default: ,]
-r, --raw
Output only raw output of processes, disables prettifying
and concurrently coloring
--no-color
Disables colors from logging
--hide <HIDE>
Comma-separated list of processes for which to hide the
output. The processes can be identified by their name or
index
-g, --group
Order the output as if the commands were run sequentially
--timings
Show timing information for all processes
-P, --passthrough-arguments
Passthrough additional arguments to commands (accessible via
placeholders) instead of treating them as commands
-p, --prefix <PREFIX>
Prefix used in logging for each process. Possible values:
index, pid, time, command, name, none, or a template.
Example template: "{time}-{pid}"
[default: [{name}]]
-c, --prefix-colors <PREFIX_COLORS>
Comma-separated list of chalk colors to use on prefixes. If
there are more commands than colors, the last color will be
repeated.
- Available modifiers: reset, bold, dim, italic, underline,
inverse, hidden, strikethrough
- Available colors: black, red, green, yellow, blue,
magenta, cyan, white, gray, any hex values for colors (e.g.
#23de43) or auto for an automatically picked color
- Available background colors: bgBlack, bgRed, bgGreen,
bgYellow, bgBlue, bgMagenta, bgCyan, bgWhite
See https://www.npmjs.com/package/chalk for more
information.
[default: reset]
-l, --prefix-length <PREFIX_LENGTH>
Limit how many characters of the command is displayed in
prefix. The option can be used to shorten the prefix when it
is set to "command"
[default: 10]
-t, --timestamp-format <TIMESTAMP_FORMAT>
Specify the timestamp in chrono::format syntax
[default: "%Y-%m-%d %H:%M:%S.%3f"]
-k, --kill-others
Kill other processes if one exits or dies
--kill-others-on-fail
Kill other processes if one exits with non zero status code
--restart-tries <RESTART_TRIES>
How many times a process that died should restart. Negative
numbers will make the process restart forever
[default: 0]
--restart-after <RESTART_AFTER>
Delay time to respawn the process, in milliseconds
[default: 0]
-h, --help
Print help information (use `-h` for a summary)
-V, --version
Print version information
Why?
I like the UX of concurrently
, but dislike having to install NodeJS / npm to use it. My goal is to make rly
accessible via Homebrew (and potentially other package managers), so that installation only requires downloading a single binary.
