Somewhere, over all the place
It feels like I'm all over the place currently. I can't decide what to focus on. I have however managed to implement a new library: javalangreflect.library. I told you about it previously when trying to run the JGit git client. I reached some success, as in "it started".
See output below:
Get git-ing with it
3.Mauve:Projects/jgit/jgit> jamiga:jamvm -Dgnu.classpath.home.url=file:jamiga:classpath org.eclipse.jgit.pgm.Main
jgit --git-dir GIT_DIR --help (-h) --show-stack-trace --version command [ARG ...] The most commonly used commands are: add Add file contents to the index archive zip up files from the named tree branch List, create, or delete branches checkout Checkout a branch to the working tree clone Clone a repository into a new directory commit Record changes to the repository config Get and set repository or global options daemon Export repositories over git:// describe Show the most recent tag that is reachable from a commit diff Show diffs fetch Update remote refs from another repository gc Cleanup unnecessary files and optimize the local repository init Create an empty git repository log View commit history ls-remote List references in a remote repository ls-tree List the contents of a tree object merge Merges two development histories push Update remote repository from local refs reflog Manage reflog information reset Reset current HEAD to the specified state rm Stop tracking a file show display one commit status Show the working tree status tag Create a tag version Display the version of jgit 3.Mauve:Projects/jgit/jgit>
However, trying to get status from a repository only resulted in AmigaDOS requests for disks named "git:". I don't know how its supposed to work, but the Git URI does indeed look like "git://git.berlios.de/jamvm". So I'm not very surprised. I guess I really should try and get the Git client working on another Java system first. So that I know my command line syntax is correct.
Trying to J-focus
This week I'm however really Java focused, as I'm attending Sweden's largest Java conference: Jfokus. Today I listened to stuff on Java 8 and Java 7. Cool stuff indeed! And it makes me really want to go the OpenJDK route, and get us updated, from Java 5 to Java 8. But I also want to get some GUI stuff in order, before I commence a new, I'm fearing long-going route. Furthermore, I really don't want to WET, but rather stay DRY; so I keep telling myself "Don't Repeat Yourself". After my ill-fated Git try (but in some ways successful, I got a new library!), I looked at the GUI code in JAmiga. And in GNU classpath in general. And in OpenJDK. And then I got tired. There are so many classes! And so many native calls!
Gad only knows
Regarding the JAmiga GUI/AWT implementation, it uses GadTools. I would like to use ReAction, since its, a) what OS4 should use, and b) I think its easier to connect it to Java, with it being object oriented. In essence I'm naïvely thinking it'd be sufficient with one native call to the BOOPSI call NewObject. Now, I know that it isn't that easy. But I think its far easier than using GadTool's CreateGadget.
The talented coder Andy, broadblues, Broad, with his phenomenal digital art creating program SketchBlock, has in the accompanying ProAction ARexx GUI creation package, included the source. Which I have peeked at. So, one option is to take inspiration, or even code from that (not without asking though!), and another option could perhaps be to add ARexx support to JAmiga, and get GUI support that way. The last ARexx option is tempting, since it would give me an oportunity to get ARexx to JAmiga, which would be utterly cool. What talks against it, is however speed. It would be a nasty web of intricate Java to native C-code, wrapped in strings sent to ARexx, back to native C-code, doing GUI, back to ARexx, back to native-C, back to Java. And then iterate through that scenario a few times for every little button we want in our GUI. Not something you would like to run big beasts like Eclipse or NetBeans on.
What about MUI, I hear some of you say? Well, I'm not ruling out MUI in any way. Its just that I myself have very limited knowledge of MUI. And I basically want to come up with a solution that works for both OpenJDK and GNU classpath, before I implement it for real. If that solution uses ReAction, it would be easy-peasy to change it to MUI anyways, since they both are BOOPSI.
