Looking at some of the delivered SAPUI5 code on HANA I noticed that WebStorm and even RubyMine was used by some SAP developers. I have also heard that various other developers on customer sites use WebStorm for code checked into the ABAP repository.
Both the HANA and ABAP repositories technically look to be proprietary. The default method for syncing SAPUI5 code with HANA and ABAP repos seems to be using Eclipse or the Eclipsed based HANA Studio, via SAP delivered plugins installed.
I searched and couldn't find any plugins or help on how you could check in and out of HANA or ABAP repo easily not using Eclipse or Orion.
For HANA you can put Github in the middle using something like the SAP HANA Deployment Shell and on the ABAP stack you can /UI5/UI5_REPOSITORY_LOAD to manually upload, i have heard alternatives for both where developers have reverse engineered the services eclipse use by listening on the HTTP traffic or de-compiling the plugins.
My question how are others using Webstorm to develop SAPUI5 applications within a team and how do you sync your code with the SAP repository?
