Spark: Ignite your development workflow
Spark is a utility to help with everything from various mundane tasks to complex database migrations and project deployment.
Installation
Download
spark.phar
and make it executable. If desired, alias spark=spark.phar
.You may also want to alias sparksh='spark repl'
.
Download the latest release from dev.noccylabs.info
and extract it into a directory somewhere, such as /tmp
:
$ mkdir /tmp/spark; cd /tmp/spark; unzip ~/Downloads/spark-0.1.0-dist.zip`
Make sure spark.phar is executable, and run the installer. Then just follow the instructions:
$ chmod +x spark.phar
$ ./spark.phar install
Afterward you will be able to call directly on spark
, as well as optionally
the sparkplug
, sparker
, sparkres
and sparksh
aliases. You can then
install any new plugins into ~/opt/spark/plugins
and enable them in your
projects with sparkplug --enable the.plugin.name
.
Using Spark
The easy way
To get started use the init
command. You still need to edit the /.spark/docker.json
and other related files as required, but his is the easy way.
$ spark init
$ sparkplug --enable com.noccy.git
The useful details
Spark expects a configuration file to either be found at ./.spark.json
or
./.spark/spark.json
relative to the project root. The ./.spark
directory
will always be used for auxillary configuration, so the placement is fully up
to you.
On its own it doesn't do much except provide a command interface to its inside. The magic can be found in preloading:
spark.json
{
"preload": [ "./.spark/plugins/*", "./.spark/autoload.php" ]
}
The preloader will go over each of the defined rules and attempt to load them in one of two ways, if applicable:
- Files with a
.php
-extension will be loaded directly. - Directories having a
sparkplug.php
file will be loaded as plugins.
The advantages of writing your extensions as flat files:
- Simple interface
- Quickly register resources for other parts of Spark
- All code evaluated on load (can be a caveat!)
The advantage of writing your extensions as plugins:
- Object-oriented interface
- Delayed evaluation of code, ensuring dependencies are loaded
- Free autoloader! The namespace and path of the plugin class will be used to set up a Psr-4 autoloader for your code.
Scripts
Using scripts is the simplest way to leverage Spark:
spark.json
{
...
"scripts": {
"hello": "./.spark/hello.php",
"world": "echo 'World'",
"greet": [
"@hello",
"@world"
]
}
}
- Call on other scripts by prepending
@
to the script name. .php
-files are executed in-process, and as such have access to any registered resources, resource types and plugins..phar
files are still executed out-of-process, as are any commands that don't match a PHP callable or any other specific rule.- Substitute shell variables using
${varname}
.
Resources
Resources are wrappers around database connections and such, providing a cleaner interface to its innards.
Resources are generally registered by plugins or local scripts.
