This is how I understand it: The instructions in ~addons/ide/jhs/config/jhs_default.ijs read as follows:
NB. JHS initialization loads 3 files in turn (if they exist) NB. ~addons/ide/jhs/config/jhs_default.ijs NB. ~addons/ide/jhs/config/jhs.ijs NB. ~config/ide/jhs/config/jhs.ijs If you want to change the default settings you can create a file called jhs.ijs located in ~addons/ide/jhs/config/ (note this file doesn't exist yet and won't be overwritten by newer versions of the ide/jhs addon). I imagine that settings defined in this file are intended to change the default settings for all users of a J installation. Alternatively you could change the default settings for a specific user by creating a file jhs.ijs in the folder ~config/ide/jhs/config/ (note that this folder and file don't exist yet), the ~config folder will normally be under your ~user folder, mine is: jpath '~config' c:/users/rsherloc/j701-user/config The latest version of the ide/jhs addon is 1.0.14 and should be downloadable using the package manager. You can check the version number you have by clicking on the "installed" button. Remember that you will need to restart your jhs instance to access the updates. > From: Joey K Tuttle > Sent: Tuesday, 10 August 2010 08:05 > > I'm still wandering around confused... > > When I install the system from the current dowload shell file, I see > that directory j64-701/addons/ide/jhs contains files dated in in > early June.
