Release v3.27.1.0

Minor usability improvements

• Added System.dll auto-referencing on EnableDbgPrint:true to allow regular expressions to be used in auto-injected dbg.cs.
• Issue #78: Beautify command line help output
• Issue #71: Issue with multiple indirect relative paths
  • Added ResolveRelativeFromParentScriptLocation for ALL non absolute paths in //css_import

Release v3.27.0.0

Use choco install cs-script to deploy the release (instructions on how to use/enable choco). Note: it may take some time before the release will appear on Chocolatey.
If you prefer manual install then avoid using WinZip or WinRar as they lead to locking the downloaded content. Use 7zip instead.

Extension Pack contains some additional content representing somewhat less mainstream functionality and experimental features. For installing it extract cs-script.ExtensionPack.7z archive to your install location (e.g. C:\ProgramData\chocolatey\lib\cs-script\tools\cs-script).

Significant usability improvements CLI and Roslyn integration. Most of he features are triggered by VSCode and Mono/Linux integration.
Most of the changes and their impact are reflected in the new CLI guide: https://github.com/oleg-shilo/cs-script/wiki/CLI---User-Guide

• CLI improvements

  • Added console out feedback for -e and -cd options (build exe and dll)
  • Added avoiding accidental decorating of VB scripts in auto-class mode (-ac CLI argument).
  • Added disabling auto-class decoration if no "main" is detected in the script.
  • Improved CLI help content
  • Added printing new config value during -config:set operation
  • Added -ac:out switch for printing auto-class decoration result.
  • removed -noconfig support
  • described -config:set:roslyn
  • added support for case insensitive property name during -config:set and -config:get
  • added support for _ separators in property name during -config:set and -config:get
  • added support for add: and del: opcodes in -config:set
  • default -ac to -ac:1
  • added command -config:set:roslyn

• Misc

  • Added 'compiler options' hash to the script metadata structure (part of 'IsOutOfDate' algorithm)
  • Setting autoClass_DecorateAsCS6 is set to true by default
  • Fixed problem with generating debug info for Mono-Debug on Windows
  • Added System to DefaultRefAssemblies on .NET (previously it was only done under Mono)
  • CSSCodeProvider.v4.7.dll replaced with CSSRoslynProvider.dll
  • Removed obsolete .NET 1 specific code
  • Removed obsolete CSScript.BuildEval code

Release v3.26.2.0

Use choco install cs-script to deploy the release (instructions on how to use/enable choco). Note: it may take some time before the release will appear on Chocolatey.
If you prefer manual install then avoid using WinZip or WinRar as they lead to locking the downloaded content. Use 7zip instead.

The most notable features of this release are the significant usability improvements particularly for supporting C# 7 on Mono/Linux. As well as the features triggered by VSCode integration.

• Linux support

  • Added "/debug:pdbonly" workaround to allow generation of debug symbols on Linux+Mono. Needed as Mono "/debug+" is broken on Linux.
  • Added resolving GAC assemblies from namespaces Mono/Linux
  • Added on-fly conversion of *.pdb to *.mdb under Mono
  • Patched Microsoft.CodeDom.Providers.DotNetCompilerPlatform to allow using Roslyn on Linux. This work around allows custom compiler (csc.exe) path and handles Mono problem when interfacing Roslyn (C#7). This is a work around for https://bugzilla.xamarin.com/show_bug.cgi?id=57130
  • Moved lock objects (*.lock files) on Linux away (to cache) from the actual folders where the files to be locked are. Just to stop pouting the file system

• Deployment

  • Default CS-Script code provider renamed to CSSRoslynProvider.dll.
  • Default code provider CSSRoslynProvider.dll embeds patched Microsoft.CodeDom.Providers.DotNetCompilerPlatform.dll to allow simplified low footprint deployment.
  • Added auto-loading CSSRoslynProvider.dll if found in the script engine folder.
  • Added resolving code provider when it is specified by file name without extension

• C# 7 and general improvements

  • dbg.print extended with direct support for IDictionary.
  • Added alias to the '-provider' switch: '-pvdr'
  • Added fully named equivalent of '-s' switch: '-sample'
  • Added C# 7 specific sample with '-s:7' switch
  • Added '-tc' switch for tracing the actual compiler input for CSSRoslynProvider.dll
  • Script engine assembly (e.g. cscs.exe) has been exposed to the precompiler routines.
  • Added ScriptParser.ProcessImportedScript to be used from precompilers.

• VSCode integration features

  • Added -stop CLI switch to stop Roslyn server if any active.
  • Added option to inject breakpoint into autoclass decoration with -ac:* switch.
  • Added Settings.RoslynDir.
  • Added 'dbg' methods extensions.
  • Added option to include injected dbg.cs file into script project printout

• Assorted defect fixes

  • Issue #73: In 3.26.0.0 running default install gives error about alternative compiler
  • Issue #71: Issue with multiple indirect relative paths
  • Issue #70: Minor issue related to platform dependent line breaks, e.g. in error messages
  • Issue #69: Basic types not available to precompilers on linux
  • Issue #68: Add option to take Main from primary script file
  • Issue #67: Same script, multiple concurrent instances, on Linux (again)

The most important features of this release are

.NET Core - Release Candidate

The CS-Script functionality for .NET Core is bound to (defined by) the scope of the currently implemented Reflection namespace found in .NET Core. Thus some CS-Script features are not ported yet. They will be as soon as .NET Core completes and releases currently missing functionality.

The full set of supported features is presented in this test code.

The binary will be published on NuGet soon.

Changes in the script caching/timestamping algorithm.

Prompted by Issue #61 CS-Script timestamp-based caching algorithm has been updated to avoid modifying compiled assemblies LastModifiedTime file attribute. Now the timestamp is injected in the assembly cs-script metadata instead of being saved as a file attribute. If for whatever reason the old believer is required you can always re-enable it as follows:

CSScript.GlobalSettings.LegacyTimestampCaching = false;

Alternatively you can set CSS_LEGACY_TIMESTAMP_CACHING environment variable to true.

Support for extension methods in classless scripts

Before this release it was impossible to have extension methods in the classless scripts due to the fact that the whole script code is wrapped in the on-fly class definition. Thus none of the extension methods from the classless script can be in a top-level class definitions but rather a nested class definition instead. This causes a compile error for the obvious reason.
space
To avoid this limitation a special directive //css_ac_end has been introduced. This directive indicates the end of the auto-class (classless) script so the runtime stops decorating any code after that directive.

//css_args -ac
using System;

void main()
{
    Console.WriteLine("\textension\ttest".TabToSpaces());
}

//css_ac_end 
static class Extensions
{
    public static string TabToSpaces(this string text, string replacement = "  ")
    {
        return text.Replace("\t", replacement);
    }
}
