Henry - this is great to have this all laid out, especially since I've made
a mish-mosh of my startup
sequence over the years and need to sort it out. I'm guilty of
over-customization and need to get my environment more plain-vanilla as it
makes it hard for me to pass along stand-alone scripts right now.
It seems fine as far as I can see - I'm taking your word for the factual
content. I would like to see
more detail on the difference between jconsole and the IDE version.
For clarity, some sort of tabular format like the following might be a
helpful addendum - apologies for the inevitable mail-related mangling which
shall ensue:
Illustrations of Startup
------------------------
Switch Result Possible Reason to
do this
------ ------ -------- -------
-jijx No IDE window standalone script
no "-jijx" IDE (session) window Normal interactive session
-jprofile [script] Run [script] first Custom startup settings
or minijx.ijs if none
no "-jprofile" Normal startup profile.ijs
Normal Startup Sequence What's Done
----------------------- -----------
profile.ijs Create
SYSTEMFOLDERS_j_
boot.ijs Update
SYSTEMFOLDERS_j_
sysenv.ijs
stdlib.ijs
colib.ijs
break.ijs
/Switch:\
1=IFCONSOLE 0=IFCONSOLE
----------- -----------
startup_console.ijs Load IDE
configuration
files:
stdcfg.ijs
~config\config.ijs
~addons\config\config.ijs
user
configuration (?)
user startup
file (?)
command script command script
I'm not sure if the user configuration and startup gets run in both cases.
