syntax highlighting - enhanceCSharpSyntax(Visual Studio 2017, TextMate) -


visual studio 2017 supports textmate grammar via visual studio extension textmate grammar. process, documented here, consist of creating folder structure under %userprofile%\.vs\extensions , creating .json file grammar (.plist seems working).

i want enhance syntax highlighting in vs2017 csharp. example, if write sql query in verbatim string, use syntax highlighting sql. textmate allows define rules embeded language, should possible.

thanks this article, came textmate grammar json

{     "name": "embeded sql",     "scopename": "source.cs.embeded-sql",     "filetypes": [         "cs"     ],     "patterns": [         {                "begin": "\\bsql\\b.*\"", // match double quoted string preceding sql, 'var sql = "select...' or 'dbexecute(/*sql*/"select...'             "end": "^\";", // ends double quote , apostrophe             "contentname": "source.sql", // scope content between <begin> , <end> 'source.sql'             "patterns": [                 { "include": "source.sql" } // include sql patterns             ]         }     ] }

but not work. problems assume:

  1. csharp grammar in vs2017 not written in textmate (?), extending way impossible,
  2. you cannot append grammar this, because opened file using 1 grammar (csharp) , cannot use both grammars (?), must either edit current csharp.tmlanguage or use grammar injection -- tried, did not work,

is there way extend csharp syntax in vs2017 way want?

appendix 1: visual studio code seems using textmate csharp language, source

appendix 2: json should valid, wrote according textmate grammar schema

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
