escaping

问题 I am using https://github.com/tokland/youtube-upload to upload videos, however, I am not able to break a line in the video description. Any way this could be done? For example, I am successful with: C:\Python35\youtube-upload-master\bin>youtube-upload --title="Title" \ --description="This is one line" --category=Music "video.mp4" I have tried adding escape sequences \\n , \n , \r\n in the middle of description but they are added without escaping (e.g. This is \\n one line ). Also tried <br />

问题 I'm asking about escaping such string: function my(mstr){alert(mstr);}; document.getElementById('home').innerHTML = '<button onclick="my("a")">a</button>' We have '<... onclick="fun("a")"...>' so its double quotes inside of double quotes inside of single quotes. Simple '<button onclick="my(\"a\")">...' gives syntax error. I know that i could escape it like '<button onclick="my(\'a\')">...' but i wonder why this syntax error appears. EDIT: here's jsfiddle for it http://jsfiddle.net/pVy9W/1/

问题 I have a URL like this: http://localhost:9001/view/shopindex/display?keyword=test&searchPostcode=Postcode and I'm putting it in the body of a new email message using HTML mailTo (I know that there are better options to mailTo but I'm restricted to this). Effectively I have this: <a href="mailto: ?subject=Look at this link&body=http://localhost:9001/view/shopindex/display?keyword=test&searchPostcode=Postcode"></a> The problem is that when I click and I get the new e-mail message opened, I get

问题 I have a simple requirement of printing text files from Windows (MS-Dos). Let's assume that my normal text file resides on "C:\Temp" folder. On the other hand, I have a EPSON TM88V receipt printer. I am able to shake hand with receipt printer connected on USB and able to print it with below command: C:\Temp> PRINT /D:\WORKSTATION\EPSONTM-T88V C:\Temp\HelloWorld.txt Though it's printing; but it's not cutting the paper. I need to insert those ESC/POS commands in my text file and pass it on to

问题 I am trying to convert from MS Access to DerbyDB. However some varchar fields have 'special' characters, such as newlines, tabs, percent marks, foreign characters etc. I created a quick method... public String charCheck(String s) { errLog.add(1, "converting string from " + s); s.replaceAll("'", "''");//an apostrophe is escaped with an apostrophy in Derby... s.replaceAll("%", "\\%");//a percent sign s.replaceAll("\\s+n", " ");//whitespace characters (newlines and tabs etc) s.replaceAll("/", "\

问题 I'm trying to search for '[EN]' in the string 'Nationality [EN] [ESP]', I want to remove this from the string so I'm using a replace method, code examaple below var str = 'Nationality [EN] [ESP]'; var find = "[EN]"; var regex = new RegExp(find, "g"); alert(str.replace(regex, '')); Since [EN] is identified as a character set this will output the string 'Nationality [] [ESP]' but I want to remove the square brackets aswell. I thought that I could escape them using \ but it didn't work Any

问题 My code doesn't work as expected : import subprocess key = 'reg delete HKEY_USERS\S-1-5-21-2637495828-1099793317-3825703309-1000\SOFTWARE\Classes\CLSID\{0E270DAA-1BE6-48F2-AC49-D955BE4EEF1D} /f' subprocess.call(key, shell=True) Running Windows 10 64b, tried with subprocess.Popen aswell. My first thought is I have to escape \ somehow, but I'm not sure if that's what I need, nor how to do it. I also tried to make it work with a list of args key = ['reg', 'delete', 'HKEY...']) , which gave the

问题 I need to build an re pattern based on the unicode string (e.g. I have "word", and I need something like ^"word"| "word"). However the "word" can contain special re characters. To match the "word" as it is, I need to escape special re characters in unicode string. The basic re.escape() function does the job for ascii strings. How can I do this for unicode? 回答1: re.escape() inserts a backslash before every character that's not an ASCII alphanumeric. This may in fact lead to a multitude of

问题 I am writing some html code to an SQL databse using RMySQL (but I guess my problem is rather a general R question than really related to SQL or RMySQL). So I am trying something like this: con <- RMySQL(...) # some connection html <- "<div style='text-align: center; font-family: Arial;'><span style='font-size: 14pt;'>Some text without any tricky symbols.</span></div>" query <- c('INSERT INTO table (htmlfield) VALUES (\"', html, '"') dbSendQuery(con,paste(query, collapse = "")) Trouble is, R's
