Java library providing APIs for parsing and exporting information
on PDS4 table and image objects to various formats including CSV, PNG, Vicar,
Fits, etc. The software is packaged in a JAR file.

Please visit the website https://NASA-PDS.github.io/pds4-jparser/ for information on installation, use, operation, and also *development* of this software.

# System Requirements
Current software requires:
* Maven 3

# Documentation
The documentation including release notes, installation and operation of the
software should be online at https://NASA-PDS.github.io/pds4-jparser/. If it is not
accessible, you can execute the "mvn site:run" command and view the
documentation locally at http://localhost:8080.

# Build

The software can be compiled and built with the "mvn compile" command but in order
to create the JAR file, you must execute the "mvn compile jar:jar" command.

In order to create a complete distribution package, execute the
following commands:

```
mvn site
mvn package
```

# Operational Release

## Run pre-build software

When new PDS4 Information Model is available, run the following script to download the latest IM and
push to git.

```
$ build/pre-build.sh

pre-build.sh
dev_or_ops - still in dev or released
IM Version - e.g. 1D00

# For dev release of IM
build/pre-build.sh dev 1E00

For operation release of IM
build/pre-build.sh ops 1E00
```

## Release with ConMan

For internal JPL use, the ConMan software package can be used for releasing software, otherwise the following sections outline how to complete these steps manually.

## Manual Release

Note that GitHub Actions are enabled for the repository of this software so that automated SNAPSHOT and stable releases are available. Manual release instructions follow below.

### Update Version Numbers

Update pom.xml for the release version or use the Maven Versions Plugin using [semantic versioning](https://semver.org/). For IM release candidates and operational releases, PDS4 JParser will be built and deployed as an operational release and versioned and re-build if needed.

```
VERSION=1.1.0
mvn versions:set -DnewVersion=$VERSION
```

### Update Changelog
Update Changelog using [ Changelog Generator](https://github.com/github-changelog-generator/github-changelog-generator). Note: Make sure you set `$CHANGELOG_GITHUB_TOKEN` in your `.bash_profile` or use the `--token` flag.
```
github_changelog_generator --future-release v$VERSION
```

### Commit Changes
Commit changes using following template commit message:
```
[RELEASE] PDS4 Java Parser Library v$VERSION
```

### Build and Deploy Software to [Sonatype Maven Repo](https://repo.maven.apache.org/maven2/gov/nasa/pds/).

```
mvn clean site deploy -P release
```

Note: If you have issues with GPG, be sure to make sure you've created your GPG key, sent to server, and have the following in your `~/.m2/settings.xml`:
```



true


gpg
KEY_NAME
KEY_PASSPHRASE

```

### Push Tagged Release
```
git tag v$VERSION
git push --tags
```

### Deploy Site to Github Pages

From cloned repo:
```
git checkout gh-pages

# Create specific version site
mv target/site $VERSION
rm -fr target

# Sync latest version to ops
rsync -av $VERSION/* .
git add .
git commit -m "Deploy v$VERSION docs"
git push origin gh-pages
```

### Update Versions For Development

Update `pom.xml` with the next SNAPSHOT version either manually or using Github Versions Plugin, e.g.:
```
git checkout main
VERSION=1.16.0-SNAPSHOT
mvn versions:set -DnewVersion=$VERSION
git add pom.xml
git commit -m "Update version for $VERSION development"
git push -u origin main
```

### Complete Release in Github
Currently the process to create more formal release notes and attach Assets is done manually through the [Github UI](https://github.com/NASA-PDS/pds4-jparser/releases/new) but should eventually be automated via script.

## Snapshot Release
1. Checkout the main branch.

2. Deploy software to Sonatype Maven repo:
```
mvn clean site deploy
```
