ذخیره‌سازی تقییرات شل درون پروفایل

نکته‌ایی که باید به آن دقت داشته باشید این است که تغییرات، تنها برای سشن جاری ذخیره خواهند شد و به محض بستن سشن، این تغییرات از حافظه پاک خواهند شد. همانطور که در قسمت قبل نیز اشاره شد، برای اینکه تغییرات را همیشه موقع باز کردن شل مشاهده کنیم، باید کدها را درون پروفایل ذخیره کنیم. به این معنا که هر وقت PowerShell را باز کنیم، توابع و کدهایی که درون پروفایل تعریف شده باشند، به صورت سراسری قابل استفاده خواهند بود. توسط متغیر خودکار Profile$ میتوانیم پروفایل جاری را مشاهده کنیم:  

PS /> $Profile

{HOME_USER}/.config/powershell/Microsoft.PowerShell_profile.ps1

دقت داشته باشید که پرفایل فوق، برای Host جاری و همچنین کاربر جاری میباشد. به این معنا که محتویات داخل این پروفایل، تاثیری در دیگر شل‌هایی که توسط اپلیکیشن‌های دیگر میزبانی میشوند ندارد. توسط دستور زیر میتوانید لیست پروفایل‌ها را مشاهده نمائید: 

PS /> $PROFILE | Get-Member -Type NoteProperty | Select-Object Name, Value

Name                   Value
----                   -----
AllUsersAllHosts
AllUsersCurrentHost
CurrentUserAllHosts
CurrentUserCurrentHost

مسیر هر کدام از پروفایل‌های فوق را میتوانید در اینجا مشاهده نمائید. همچنین توسط پرچم NoProfile- میتوانیم PowerShell را بدون بارگذاری هیچ پروفایلی باز کنیم: 

pwsh -NoProfile

بنابراین برای ذخیره‌ی تغییرات قبل، میتوانیم توابع تعریف شده را درون پروفایل موردنظر قرار دهیم، تا با هربار باز شدن سشن، کدهای موردنظر قابل استفاده باشند: 

PS /> code $PROFILE.CurrentUserCurrentHost

Function Write-Branch {
    # As before
}


Function Prompt {
    # As before
}

اگر از ماژول Posh برای تغییر ظاهر PowerShell استفاده کرده باشید، متوجه خواهید شد که این ماژول نیز به همین روال کار میکند؛ یعنی با هربار باز شدن سشن، این دستور برای بارگذاری Prompt سفارشی فراخوانی خواهد شد: 

oh-my-posh init pwsh | Invoke-Expression

a fresh re-write of the TypeScript Handbook is out of beta and is now our website’s primary resource for learning TypeScript! 

This post shows how to import and export .xls or .xlsx (Excel files) in ASP.NET Core. And when thinking about dealing with excel with .NET, we always look for third-party libraries or component. And one of the most popular .net library that reads and writes Excel 2007/2010 files using the Open Office Xml format (xlsx) is EPPlus. However, at the time of writing this post, this library is not updated to support .NET Core. But there exists an unofficial version of this library EPPlus.Core which can do the job of import and export xlsx in ASP.NET Core. This works on Windows, Linux and Mac. 

Improved the MSBuild selection logic. The standalone instance inside OmniSharp is now preferred over VS2017, with VS2019 given the highest priority. This ensures that .NET Core 3.0 works correctly. It is also possible manually provide an MSBuild path using OmniSharp configuration, which is then always selected. (omnisharp-roslyn#1541, PR: omnisharp-roslyn#1545)

    {
        "MSBuild": {
            "MSBuildOverride": {
                "MSBuildPath": "C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Enterprise\\MSBuild\\15.0\\Bin",
                "Name": "vs2017 msbuild"
            }
        }
