Initially for me the un staged resources area showed as the first entries the newly added resources, followed by the modified resources. Somehow after I staged one newly added resource, the other newly added resource appeared at the end of the list so the entire list seemed to be resorted.
Ideally in the unstaged resources area we should sort and first show the newly added resources followed by the modified ones.
Or add some sorting widget to allow sorting by file path or file status.

Make it ask end user for confirmation.
Make it work on multiple selected resources when you right click them, on when right clicking a folder if the display is hierarchical.

Currently you can only switch between local branches. We should also present the remote branches and allow the user to check out these remote branches. Maybe more? Perhaps others can tell us what branch-related functionality they find useful and use relatively often.

Another suggestion borrowed from Git GUI clients such as GitHub Desktop and Tower:

Current behavior

To view a diff, the user must double-click on a changed file in the Working Copy view, which opens a new window with the diff. Then the user must close or move this window before being able to return to the main window

Proposal

Upon selecting (with a single click) a changed file in the Working Copy view, a preview of the diff should appear in a pane. This would allow a user to quickly preview the changes in a file before deciding whether to stage it.

A future enhancement would be to select lines within a diff to stage.

Here is screenshot taken from GitHub Desktop showing how selecting a changed file displays a preview of the diff:

Those "Stage" buttons added to the right of each entry seem to be very many and the list gets crowded. How about if we add it as a contextual menu action?
Also the unstage button seems not to display the entire message on my side:

It's wanted (but annoying) behavior, that a submodule always points to a commit hash and not to a branch. So it's a common and wanted (but annoying) situation, that submodules fall in a detached head state.

Oxygen should warn, that the head is detached and ask the user to pick a branch, because that's what he always wants. But Oxygen should not checkout a random branch, because that would also lead to unexpected results.

When our Bitbucket password changes, there doesn't seem to be a way to change the username/password that is used by the plugin.

I would somehow wish not to need other Git clients to be installed or to have the git command line in order to clone a repository and start working with it from Oxygen.

For example for a file add an action to commit it or to show it in the Git View.
The API to add contextual menu actions to the project will be available in Oxygen 19.1. See more details here:

Great work so far! I've already made my first commit with the plugin, and it worked very smoothly. Coming from other GUI git clients, such as GitHub Desktop, there are a couple of features I would like to see before I begin using this regularly. I'll put them into issues—this being the first:

Currently staging is controlled with two lists. To stage one or more files, select them in the "unstaged" list and click Stage Selected (or select Stage All).

My proposal would be to collapse these two lists into one, and place a checkbox next to each file. Checking a file stages it; unchecking it unstages it. I think this would simplify the UI for users.

Here screenshot to illustrate this UI in GitHub Desktop:

Note that 1.xml and 3.xml are staged, and 2.xml is unstaged. Note also the checkbox above the list of files which indicates some are stages; clicking this checkbox toggles between staging all and none.

after installing the plugin I get this error message box when I try to start Oxygen (version 17.1 MacOs)

I can close the dialog and oXygen seems to work properly, I can open the Git Staging window/tab, but it is grey and empty.

The fileas a represented like this:
file_name - file_path
I would gray out the path so that the file name is more visible.

As asked here:
https://www.oxygenxml.com/forum/post44586.html#p44586

Use only icons designed by us.
For the push and pull buttons position the figures to be on the arrow stem instead of being on the right bottom part like now.

Would be nice to have an option to switch to another branch.

Travis could create GitHub releases automatically. We have such an example here: https://github.com/oxygenxml/web-author-rest-connector/blob/BRANCH_OXYGEN_RELEASE_19_0/.travis.yml.

Git GUI clients like GitHub Desktop and Tower provide two fields for commit messages - a one-line Summary field (which invites brief, ~50 character summaries) and a multiline Description field (which invites longer descriptions if needed).

A screenshot showing this in GitHub Desktop - before text has been entered:

After text has been entered:

I imagine that since this oXygen Git UI is designed to fit inside a sidebar pane, you're working with constrained space. If #23 is adopted, though, it could potentially reclaim a lot of space, some of which could go to this additional field.

I have an oXygen project that houses about 20 git repositories. I'd like to add them all to Git Staging's list of working copies.

Currently the only way to add a repository is to select the "Browse File System" icon in the Git Staging pane.

I would like to be able to drag-and-drop 1+ folders from the Project pane (or the Finder) onto the Git Staging pane to register them with the plugin as working copies.

Ideally, I'd also like to be able to register a repository programmatically - so that I could configure an External Tool to call a script that could populate a set of repositories as working copies.

p.s. I just tried out the plugin again after a couple of months and can see it's been progressing nicely!

If you open an xpr that is not a Git project, when switching to the Git Staging view, we could ask the user if he wants to create a local repository. This would result in a .git directory and the initialization of the view with that repository.

Because of #21 the user will be able to work normally with the repo and bind it to a remote later on.

Now the contextual menu action is active also for newly added files.

Right now they do not properly work anyway as each side of the scroll pane has a minimum size set to it.

As requested here:
https://www.oxygenxml.com/forum/post44586.html#p44586

The plugin is very slow to update the list of files, especially when trying to stage individual selected files. We've seen this on both Windows and Mac.

For a branch or current branch, present the commits, their message, what resources change (with the possibility of a diff) etc.

As asked here:
https://www.oxygenxml.com/forum/post44586.html#p44586

We have an editor variable called ${pdu} which can be expanded using the API to the current project. So we can expand this editor variable each time focus is gained in the git view to see if the current project folder changed and if it is a git project.

The plugin shows the error message Cannot reach host. Connection via SSH by CLI works. How can I fix that?

This string cannot be translated at the moment.

This exception is shown in a modal dialog when launching oXygen after plugin installation:

I'm running oXygen Editor 19 in de_DE locale on a Mac.

On a Mac, two junk files you shouldn't check in are:

Icon
.DS_Store

The Icon one is "special" in that the file name contains a carriage return (i.e. Icon^M), which reduces the possibility of a naming conflict. Right now Icon files show up as being Staged, despite being listed in .gitignore. Since the .DS_store files are not showing up, I suspect the problem is handing special characters in the file name.

Especially in the tree view, whenever the view detects changes and refreshes the presented resources it should restore the expanded paths (for the tree) and the selection.

Here's how this is done:
oxygenxml/oxygen-docbook-validate-check-completeness#9

If I perform Discard or Stage on a resource the entire tree gets collapsed. it should keep its expanded state because I will definitely continue to stage/discard resources.

For example if I make changes in Source Tree and then switch to Oxygen the entire Git view should refresh. Right now the "Unstaged" resources seems to refresh. But the list of already staged resources or the counters on the buttons used to Push or Pull resources seem to remain with stale info.

The situation is now that I can only do regular work in Oxygen after providing the user name and password for a remote on Gitlab. I would understand that after canceling the authentication there is no push or pull available.

All warning messages should have the warning icon and also avoid using bold text in message.

WSOptionsStorage optionsStorage = pluginWorkspaceAccess.getOptionsStorage();

You could store the serialized options on a key in the options storage:

	/**
	 * Uses JAXB to save all the selected repositories from the users in the
	 * repositoryOptions variable
	 */
	private void saveRepositoryOptions() {
		try {

			JAXBContext jaxbContext = JAXBContext.newInstance(Options.class);
			Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
			jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
			
			StringWriter stringWriter = new StringWriter();
      jaxbMarshaller.marshal(options, stringWriter);
      
      PluginWorkspaceProvider.getPluginWorkspace().getOptionsStorage().setOption(
          "MY_PLUGIN_OPTIONS", 
          PluginWorkspaceProvider.getPluginWorkspace().getXMLUtilAccess().escapeTextValue(stringWriter.toString()));
		} catch (JAXBException e1) {
			e1.printStackTrace();
		}
	}

	/**
	 * Uses JAXB to load all the selected repositories from the users in the
	 * repositoryOptions variable
	 */
	private void loadRepositoryOptions() {
		if (options == null) {
			options = new Options();
			try {
				JAXBContext jaxbContext = JAXBContext.newInstance(Options.class);
				Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
				
				
				 String option = PluginWorkspaceProvider.getPluginWorkspace().getOptionsStorage().getOption(
		          "MY_PLUGIN_OPTIONS", null);

				 if (option != null) {
				   options = (Options) jaxbUnmarshaller.unmarshal(
				       new StringReader(
				           PluginWorkspaceProvider.getPluginWorkspace().getXMLUtilAccess().unescapeAttributeValue(option)));
				 }
				
			} catch (JAXBException e) {
				logger.warn("Options not loaded: " + e, e);
			}

		}
	}

Currently, when a (new) string is not translated (like the ones with 1.0.8 version) the user just sees "de_DE_translation" instead of a proper label.

From other Java projects I'm used that there is a fallback mechanism to the default/english language tag. Any chance to implement this?

The authenticity of host '...' can't be established.
RSA key fingerprint ...
Are you sure you want to continue connecting?

This message is shown on every oXygen startup. Why doesn't it cache my choice "Yes"?

Why is it shown anyway? The fingerprint is okay, Sourcetree isn't asking for it everytime?

JGIT uses the slf4j library. We should also distribute an implementation otherwise this implementation might be located in the main Oxygen class loader which will end badly...

<!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-log4j12 --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.25</version> <scope>test</scope> </dependency>

When working with submodules, you often have changes in the submodule git files when you commit something in the submodule.

Diffing those files results in an error in the oXygen Diff (cannot open/read the file).

In those cases you should considder diffing the .git file in the submodule directory instead.

1. If I rename a file using git mv old_filename new_filename I expect to see just the new file with a "Renamed" status/icon. The Diff should also be performed between the old and the new files because other changes might have been made (besides the rename). Right now we present the new file as added and the old one as deleted.

2. It would be great if we can intercept the "Rename" action from Oxygen's Project view and use a git mv if the resource is under Git version control.

In our workflow, we use git hooks to check the validity of commit messages (e.g., they must contain a valid issue ID). The git integration also seems to run the hooks, so a commit is rejected, if the commit message is not valid.
Though the commit is not applied, the git staging view tells erroneously that everything was fine. Like the git integration in Egit/Eclipse, it would be better to evaluate the return values of the git hooks and to display the error messages if the commit went wrong.

I have some feature branches checked out:

eike@P01470 MINGW64 ~/DITA/globaledition (develop)
$ git branch -l
  DAKDOK-780
* develop
  feature/DAKDOK-716
  feature/DAKDOK-739
  feature/DAKDOK-781
  feature/DAKDOK-789
  master

  release/SU_DakosyGE_ExportAT_1.0
  release/SU_GlobalEdition_EZT_1.0
  release/SU_GlobalEdition_Export_2.3
  release/dakosy-ge-5.4

oXygen detects the branches, but drops/ignores the branch type, e.g. feature/.

Because of that, JGit writes a messy stacktrace on checkout, because the branch cannot be found, because the correct branch name is feature/DAKDK-789.

Let's test how the plugin works with local repositories, ones that don't have a remote yet. The Pull, Push, Switch Branch actions be aware of these special repos.

These actions that require a remote, might ask you for a remote URL, remote name and bind them:
git remote add <remote_name> <remote_repo_url>

I closed Oxygen while the Git Staging view was floating.
