powershell - how to prevent external script from terminating your script with break statement -


i calling external .ps1 file contains break statement in error conditions. somehow catch scenario, allow externally printed messages show normal, , continue on subsequent statements in script. if external script has throw, works fine using try/catch. trap in file, cannot stop script terminating.

for answering question, assume source code of external .ps1 file (authored else , pulled in @ run time) cannot changed.

is want possible, or author of script not thinking playing nice when called externally?

edit: providing following example.

in badscript.ps1:

if((get-date).dayofweek -ne "yesterday"){     write-warning "sorry, can run script yesterday."     break }

in myscript.ps1:

.\badscript.ps1 write-host "it today."

the results achieve see warning badscript.ps1 , continue on further statements in myscript.ps1. understand why break statement causes "it today." never printed, wanted find way around it, not author of badscript.ps1.

edit: updating title "powershell try/catch not catch break statement" "how prevent external script terminating script break statement". mention of try/catch more 1 failed solution actual question new title better reflects.

i you're coming from. easiest way push script off job, , wait results. can echo results out receive-job after it's done if want.

so considering bad script have above, , script file calling it:

$path = split-path -path $myinvocation.mycommand.definition -parent  $start = start-job -scriptblock { . "$using:path\badscript.ps1" } -name "badscript"  $wait = wait-job -name "badscript" -timeout 100 receive-job -name "badscript" get-command -name "get-childitem"

this execute bad script in job, wait results, echo results, , continue executing script it's in.

this wrapped in function scripts might need call (just on safe side.

here's output:

warning: sorry, can run script yesterday.  commandtype     name                                               version    source -----------     ----                                               -------    ------ cmdlet          get-childitem                                      3.1.0.0    microsoft.powershell.management

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
