Blaze by Fizzed

Command-line

When you execute java -jar blaze.jar these are the command-line options

blaze: [options] <task> [<task> ...]
-f|--file <file>  Use this blaze file instead of default
-d|--dir <dir>    Search this dir for blaze file instead of default (-f supercedes)
-l|--list         Display list of available tasks
-q                Only log blaze warnings to stdout (script logging is still info level)
-qq               Only log warnings to stdout (including script logging)
-x[x...]          Increases verbosity of logging to stdout
-v|--version      Display version and then exit
-Dname=value      Sets a System property as name=value

Running on a JRE

If you are using .java scripts then those will need to be compiled. As long as you're running a JDK or a Server JRE then you'll be okay. However, if you do need to run on a JRE or ensure you're script always runs regardless then simply adding the Eclipse compiler as a runtime dependency will work. There are two ways. First, you can create a blaze.conf file in the same directory as your blaze.java file and add it:

blaze.dependencies = [
  "org.eclipse.jdt.core.compiler:ecj:4.6.1"
]

Alternatively, you could supply it from the command-line:

java -jar blaze.jar -Dblaze.dependencies.0=org.eclipse.jdt.core.compiler:ecj:4.6.1

Globbing

Finding and working with files and directories is one of the most common scripting tasks. One nice part of shell scripts is that you can take advantage of globbing syntax to find files or directories. Blaze provides excellent support for globbing with a utility wrapper around Java's own glob support. The Java documentation on globbing is a good start , but here are some examples as well.

Statically import the Globber.globber method

import static com.fizzed.blaze.util.Globber.globber;

Find all paths in the current working directory with ending with .md

List<Path> paths = globber("*.md").scan();

Find all paths recursively in the current working directory with ending with .md

List<Path> paths = globber("**/*.md").scan();

Find all paths recursively ending with .md but from a different base dir

List<Path> paths = globber("../a/different/path", "**/*.md").scan();

Many blaze commands accept a globber object (no need to call .scan() on it either)

Systems.remove(globber("**/*.md")).run();
