JPad now provides a JPad class to provide users with handy functions.
This includes functions for:
- Running Terminal Commands
- Writing out Objects to CSV files
For example running a command, capturing it’s output and reporting back the result as a string can be achieved using the cmd function:
Read the help section for more details.
We also added some help for adding your own jar files to jpad. This has been tested on windows, we have a rough solution for the mac/linux but we will be improving it shortly.
Ever wanted to share a problem with a colleague. A piece of java code that’s giving some strange result. Well we’ve added the ability to upload .jpad runs. You can see examples here.
Download the latest version.
This allows uploading java code aswell as the result of running that code to the website, where your friend can then view your problem or download and run it themselves.
Uploading works like this:
Help documentation on uploading is available here. If you have any problems etc. please let us know.
- Improved error reports. Console and HTML improved, shows stack to user level code
- Lighter text for highlighting error lines
- bugfix to make sure we save currently opened docs on shutdown
These additions were based on feedback from users on our forum:
http://jpad.io/b/forums/topic/feature-requests/ If you have ideas bug reports, ideas or suggestions please register and let us know.
Some requests people have already made include:
- syntax highlighting
- code upload similar to jsfiddle
- code autocomplete / intellisense
We have also open sourced our examples on github, pull requests are definitely welcome.
We present the latest release of jpad java scratchpad:
The latest additions include:
- Improved Dump() of nested lists and arrays to present them as nested tables
- Better handling of runtime exceptions, stacktraces are now provided
- Added more examples, a comparator and a euler problem example.
A user asked me “Are you familiar with the REPL in Java 9? You should leverage it”. I want to lay out why I don’t.
To me a JEP is doesn’t yet feel like the right place for what I want to do. Yes, I have a bit of a REPL
but I consider it just one facet. Most java people love GUIs, I see JPad as an environment to quickly run java code and to visualise it in many
ways. To achieve this I want:
- To take an opinionated approach to what libraries are automatically included (guava/apache,lombok..). Reducing the code clutter.
- To provide an opinionated output format (Everything is a table and shows as HTML).
I think a JEP conflicts with taking quick opinionated approaches, I realise there are reasons for this, backwards compatibility etc. but that’s not something I think is important right now. If once people show interest and a load of visualizations and toString()/console outputs were added, then would be the time to consider canonical representations I think and where a JEP would be good.
That’s my 2 cents anyway
The new version is available now to download. Mostly it includes a lot of fixes, there is one new feature, a bytecode view:
