When you double-quote a path, you’re stopping the tilde expansion. So there are a few ways to do this: cd ~/”My Code” cd ~/’My Code’ The tilde is not quoted here, so tilde expansion will still be run. cd “$HOME/My Code” You can expand environment variables inside double-quoted strings; this is basically what the tilde … Read more
escape() is defined in section B.2.1.2 escape and the introduction text of Annex B says: … All of the language features and behaviours specified in this annex have one or more undesirable characteristics and in the absence of legacy usage would be removed from this specification. … For characters, whose code unit value is 0xFF … Read more
The pyparsing wiki includes this helpful expression for matching on ANSI escape sequences: ESC = Literal(‘\x1b’) integer = Word(nums) escapeSeq = Combine(ESC + ‘[‘ + Optional(delimitedList(integer,’;’)) + oneOf(list(alphas))) Here’s how to make this into an escape-sequence-stripper: from pyparsing import * ESC = Literal(‘\x1b’) integer = Word(nums) escapeSeq = Combine(ESC + ‘[‘ + Optional(delimitedList(integer,’;’)) + oneOf(list(alphas))) … Read more
The normal operation of apache/mod_rewrite doesn’t work like this, as it seems to turn the plus signs into spaces. I don’t think that’s quite what’s happening. Apache is decoding the %2Bs to +s in the path part since + is a valid character there. It does this before letting mod_rewrite look at the request. So … Read more
\’ means $’ which is everything after the match. Escape the \ again and it works “Yaho’o”.gsub(“‘”, “\\\\'”)
Having not been able to get Uri.EscapeDataString to take on RFC 3986 behavior, I wrote my own RFC 3986 compliant escaping method. It leverages Uri.EscapeDataString, and then ‘upgrades’ the escaping to RFC 3986 compliance. /// <summary> /// The set of characters that are unreserved in RFC 2396 but are NOT unreserved in RFC 3986. /// … Read more
You can escape it using a backslash which you will have to escape. Either return dt.ToString(@”MMM d \’yy ‘at’ H:mmm”); or return dt.ToString(“MMM d \\’yy ‘at’ H:mmm”);
The correct json is: r'{“FileExists”: true, “Version”: “4.3.2.1”, “Path”: “\\\\host\\dir\\file.exe”}’ Note the letter r if you omit it you need to escape \ for Python too. >>> import json >>> d = json.loads(s) >>> d.keys() [u’FileExists’, u’Path’, u’Version’] >>> d.values() [True, u’\\\\host\\dir\\file.exe’, u’4.3.2.1′] Note the difference: >>> repr(d[u’Path’]) “u’\\\\\\\\host\\\\dir\\\\file.exe'” >>> str(d[u’Path’]) ‘\\\\host\\dir\\file.exe’ >>> print d[u’Path’] … Read more
There are two types of “escapes” involved here, HTML and JavaScript. When interpreting an HTML document, the HTML escapes are parsed first. As far as HTML is considered, the rules within an attribute value are the same as elsewhere plus one additional rule: The less-than character < should be escaped. Usually < is used for … Read more
Use printf (1): x=’a real \good %* load of c$rap’ x=$(printf ‘%q’ “$x”) echo $x will return a\ real\ \\good\ %\*\ load\ of\ c\$rap
