Develop
see more templates or propose new |
The Develop activity is the activity for making or modifying other activities. Currently, it comprises a tree view of files in an activity's directory and a python source code editor (tabbed). Other features are actively being worked on.
This is the second incarnation of such an activity. The wiki page for the previous, now broken, version is at Old Develop activity. This page has many grandiose planned features, which are worth looking at for ideas, and in general still considered desirable. However, this version is intended to be developed step-by-step, with small, working features valued over all-encompassing architectures.
Considerations
Currently this version only edits activities that are stored in ~olpc/Activities, but that at least means that you can use it to develop itself. It keeps the file data in the journal as well as in the filesystem. This means that you can restore an old version of a file by opening it up in the journal. Be careful! This can overwrite newer work if you're not.
To work, it needs you to either disable Rainbow globally or apply the patch to activiyfactory.py because it needs access to the file in ~olpc/Activities.
Roadmap
Here are some features planned for implementation relatively soon:
- creating new activities
- running the activity from Develop (see debugger idea, below)
- viewing/editing source of existing activities (by making a local copy)
- Replace
- Wrap up bundle (zip to .xo file and store in journal with correct mime type)
- exporting/importing individual (eg. svg) files from the Journal so they can be edited with other activities
Here are some features which take more work but there is somebody interested in working on them:
- A debugger based on the RPDB2 (winpdb back end) console. This would mean some significant work on providing a context for a running activity - maybe even letterboxing it inside a frame of develop. Homunq 11:26, 5 February 2008 (EST)
- Code-level l10n - see bityi Homunq 11:26, 5 February 2008 (EST)
- Rudimentary source control - z3p
Here are some features which may be desirable, but nobody is working on them. Some of these would be enormous projects and will probably never get done.
- Class browser, autocompletion, popup function signatures, refactoring aids, and similar code-editing sweets.
- Bug tracker (would have to allow users to submit bugs to a centralized repository)
- Unit testing
- Source control (ideally much of the functionality should be inherited from the journal - wait for this stuff to make it into the journal first)
- Activity sharing / Pair Coding (that is, concurrent editing of the same source file. It has been suggested that this should be implemented by replacing the editor widget with an Abiword widget; the Abiword folks have done some work in this direction.)
- Dynamic reloading of a running activity
- Visual programming
Updates
* -20 has undo/redo and find * -21 has support for jhbuid (thanks to Mike Fletcher), and is refactored a bit * -22 has a tabbed editor and a file menu
