# psfclj

PSF parser for JVM written in clojure.

## Building

Requires [Leiningen](https://leiningen.org/index.html) to run, see
their docs for more information.

### Build and Install as MAVEN dependency for Java InterOp

```bash
$ lein pom && lein install
```

### Build JAR/UBERJAR

```bash
$ lein jar
$ lein uberjar
```

### Build Standalone Executable

Simply run `make` and the `Makefile` will take care of it.
The executable will be `./target/psfconvert`.

## Usage

After building with lein you can run:

```bash
$ java -jar psfclj-0.1.0-standalone.jar [options]
```

The standalone executable can be run like so:

```bash
$ psfconvert [options]
```

Depending on the option, this will produce output to `STDOUT`.
This can be redirected to a file, or processed further with something
like [jq](https://stedolan.github.io/jq/)
or [gron](https://github.com/TomNomNom/gron).
If no `` is specified, it will try to read from `STDIN`.

### Options

- `-g ` Specify path to alternative ``.
- `-j` JSON output (default).
- `-c` CSV output (values only).
- `-h` or `--help` for a short help.

### Exit States

- `0`: Success!
- `-1`: Failed with parse error, usually caused by wrong sytnax.
- `-2`: Erronious command line arguments.
- `-3`: No output format specified.

### Example

```bash
# Read ./noise2.noise, pipe json output in gron,
# grep for "fn.xf2" of "I0.M0.m1" and inspect with bat
$ ./target/psfconvert -j ./noise2.noise | gron | grep "I0.M0.m1" | grep "fn.xf2" | bat

# Pipe json ouput into fzf for interactive search
$ ./target/psfconvert -j ./noise2.noise | gron | fzf

# Read from stdin and redirect output into file
$ cat ./noise2.noise | ./target/psfconvert -c > noise2.csv
```

## PSF BNF

The default grammar can be found in `resources/psf.bnf`:

```bnf
= *

= HEADER *
| TYPE *
| SWEEP *
| TRACE *
| VALUE *
| END

= [] []
|
| []

= " * "

= " * "

values =
| ( * )

= #'\S+'
| " * "

=
| *

= FLOAT
| DOUBLE
| COMPLEX

= PROP( * )

= STRUCT( * )
```

## Java API Reference

After installing with

```bash
$ lein pom && lein install
```

the `psfclj*.jar` should be in your local repository and classpath.

### Example

```java
import java.io.File;
import java.io.IOException;
import org.apache.commons.io.FileUtils;
import clojure.lang.APersistentMap;
import psfclj.PSFParser.Parser;

public class PSFParserExample {

public static void main(String[] args) throws IOException {

Parser parser = new Parser();

String psfContent = FileUtils.readFileToString(
new File("./noise2.noise"));

APersistentMap map = parser.parsePSF(psfContent);

}
}
```

## TODO

- [X] CSV Output
- [ ] Comment Code
- [ ] Read PSF with `` in `VALUE` section.
- [ ] Implemented tests
- [ ] XML Output
