2017 June beta

JHS now always binds to any rather than local host.

BIND and LHOK config options are no longer used.

Login:

USER/PASS login required if access from lan or external ip.
USER_jhs_/PASS_jhs can be changed in the JHS session
JHS could start with them as  and then set them to allow temporary login
permanent USER/PASS set in config

getlanip - returns ip for access from other machines on the lan

getexternalip - returns ip for access from www (probably requires router config)

OKURL is list of urls that are allowed access without login these pages should provide their own password security checks

preliminary support for JHS services to J mobile devices (e.g., iOS J)

jtoj.ijs       - OKURL page on the server
jtojclient.ijs - provide

2017 January

link menu removed from all pages except jijx
page open behaves differently

Previously, depending on menu vs button vs jijx sentence and browser (Firefox/Edge/...) and browser version an open could:

open a new tab (that is, 2 tabs for the same page)

reopen in the same tab, but not switch focus

reopen in the same tab and switch focus

This is an area (pop-up and switching focus) where browsers fight a battle against badly behaved sites and systems like JHS trying to provide a more desktop like application suffer.

JHS generally opens a page in a window/tab with an id. Page jfif opens in a tab with an id of jfif. Opening jfif again will close the current jfif tab and open in a new tab.

This is not perfect, but is consistent and avoids:

duplicate tabs (unnecessary clutter and can be confusing)

having to hunt for a tab that existed and wasn't given focus

jquery javascript library easily integrates with the JHS framework - see jd3 and jtable
jfiles - list recent files
ctrl+shift+up/down arrow recall
jijx - recall input lines
jfile - recall folders
jfif - recall what/where text lines
browser local storage carries recalls over J task sessions

jijx - menu action|clear refresh (refresh log)
jijx - menu action|clear LS (local storage recalls)
browser javascript calls to J are synchronous
Previously if J was busy an event for J got a busy alert and was discarded. The alert was a nuisance if the delay would have been brief. Now events are queued and will fire when J call completes. This avoids alerts, but remember the queue, and don't go click crazy when you don't see expected responses.
jlog utility removed
minor bug fixes
