PowerShell Out-file -width does not truncate content when exporting to a file -


i have windows 7 , powershell 4.0. when exporting content file -width parameter not format based on given setting. here sample of trying do:

"it nice hot sunny day" | out-file -filepath ".\output.txt" -encoding ascii -width 10

the result of export not truncated @ 10th character. not truncated @ all. cannot figure out what's wrong.

this came of surprise me, apparently, -width parameter works formatted objects:

string(s) input, no effect

ps c:\> "it nice hot sunny day" |out-file '.\output.txt' -width 10 -force; gc '.\output.txt' nice hot sunny day

format-table, works

ps c:\> new-object psobject -property @{text="it nice hot sunny day"} | format-table |out-file '.\output.txt' -width 10 -force; gc '.\output.txt'  text ----- a...

format-list, works, in strange manner:

ps c:\> new-object psobject -property @{text="it nice hot sunny day"} | format-table |out-file '.\output.txt' -width 10 -force; gc '.\output.txt'  text :               n        ice         ho        t s        unn        y        day

so, closest can propably format-table -hidetableheaders:

ps d:\> new-object psobject -property @{text="it nice hot sunny day"} | format-table -hidetableheaders|out-file '.\output.txt' -width 10 -force; gc '.\output.txt'  a...

inspired @matt's answer, write own function truncate strings:

function resize-string {     param(         [parameter(mandatory=$true,valuefrompipeline=$true)]         [string[]]$inputobject,         [int]$width = 10     )      process{         $inputobject.substring(0,[system.math]::min([string]$inputobject[0].length,$width))     } }  ps c:\> "it nice hot sunny day" |resize-string|out-file '.\output.txt' -width 10 -force; gc '.\output.txt' ni

go - Idiomatic way to handle template errors in golang -

say have html/template following: <html> <body> <p>{{somefunc .somedata}}</p> </body> and somefunc returns error. there idiomatic way deal this? if write directly responsewriter , status code 200 has been written before encounter error. var tmpl *template.template func handler(w http.responsewriter, r *http.request) { err := tmpl.execute(w, data) // "<html><body><p>" has been written... // err? } preferably return status code 400 or such, can't see way if use template.execute directly on responsewriter . there i'm missing? since template engine generates output on-the-fly, parts of template preceding somefunc call sent output. , if output not buffered, (along http 200 status) may sent. you can't that. what can perform check before call template.execute() . in trivial case should enough call somefunc() , check return value. if choose path , return value of somefunc() c...
