osx - Why when I use p2.director to install Eclipse Mars.2 on Macosx there is no launcher? -

-

i installing eclipse mars.2 ide on mac pointing p2.director eclipse platform 4.5.2 repository, , completes without error, there not launcher.

here command use:

./eclipse -nosplash -application org.eclipse.equinox.p2.director -profileproperties org.eclipse.update.install.features=true -roaming -repository http://download.eclipse.org/eclipse/updates/4.5/r-4.5.2-201602121500 -installiu org.eclipse.sdk.ide -bundlepool /home/me/ecl452 -destination /home/me/ecl452 -p2.os macosx -p2.ws cocoa -p2.arch x86_64 -profile sdkprofile

there no errors, reports it's installing org.eclipse.sdk.ide 4.5.2.m20160212-1500, , completes "operation completed in 101165 ms". there no "eclipse.app" folder in destination, , no eclipse launcher file. resulting destination folder has this:

-rw-r--r--  .eclipseproduct  -rw-r--r--  artifacts.xml  drwxr-xr-x  configuration drwxr-xr-x  dropins -rw-r--r--  eclipse.ini  drwxr-xr-x  features drwxr-xr-x  p2 drwxr-xr-x  plugins drwxr-xr-x  readme

i kind of thing windows , gives me "eclipse.exe" properly, doing wrong on mac?

adding ".app" both -bundlepool , -destination parameter values resulted in launchable eclipse instance executable located in following folder:

/home/me/ecl452.app/contents/macos/eclipse

it seems when folder name ends ".app" p2.director recognizes should setup installation mac application, other folder name skips application setup step without warning or error.

for completeness, here command worked:

./eclipse -nosplash -application org.eclipse.equinox.p2.director -profileproperties org.eclipse.update.install.features=true -roaming -repository http://download.eclipse.org/eclipse/updates/4.5/r-4.5.2-201602121500 -installiu org.eclipse.sdk.ide -bundlepool /home/me/ecl452.app -destination /home/me/ecl452.app -p2.os macosx -p2.ws cocoa -p2.arch x86_64 -profile sdkprofile

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
