• remove words containing non-alpha characters

  - by dnkb

  Given a text file with space separated string and a tab separated integer, I'd ;like to get rid of all words that have non-alpha characters but keep words consisting of alpha only characters and the tab plus the integer afterwards. My attempts like the ones below didin't yield any good. What I was trying to express is something like: "replace anything within word boundaries that starts and ends with 0 or more whatever and there is at least one :digits: or :punct: in between". sed 's/\b.[:digits::punct:]+.\b//g' sed 's/\b.[^:alpha:]+.\b//g' What am I missing? See sample input data below. Thank you! asdf 754m 563 a2a 754mm 291 754n 463 754 ppp 1409 754pin 4652 pin pin 462 754pins 652 754 ppp 1409 754pin 4652 pi$n pin 462 754/p ins 652 754 pp+p 1409 754 p=in 4652

• Public IP shows strange characters and Facebook registers logged-in session to a different location

  - by Stuart Kershaw

  I'm encountering some IP strangeness today and hoping to find an explanation. In short, I'm based in Seattle, WA with my ISP being Comcast. While browsing Facebook's account settings, I noticed that my active session was located to Mount Laurel, NJ. At that point I ran a search in Google for 'my public IP', which returned an interesting result: a string of characters in the following format: 2601:8:b000:xxx:xxxx:xxxx:xxxx:xxxx Normally, a search for my IP returns something like: 67.xxx.xx.xxx A phone call to Comcast got me nowhere, but using Comcast's phone-menu debugging tools, I was able to send a 'refresh signal' to my modem. After that, the search for 'my public IP' yielded the expected result... for about 5 minutes, and then it returned to the new string of characters. Does anyone know of an explanation for this?

• Why are unicode characters not rendering correctly

  - by sw1nn

  Background: I have some unicode characters in my prompt (git status markers essentially) I'm running urxvt under xfce on arch linux. I'm using DejaVu Sans Mono for Powerline font, specified via .Xresources line: URxvt*font: xft:DejaVu Sans Mono for Powerline:pixelsize=14 When I start urxvt the unicode characters do not render correctly. For example ? renders as â However, if I then start a new urxvt from inside the first terminal everything renders correctly. There doesn't appear to be any difference in the environment between the two terminals. What could be the difference between the first invocation and the nested invocation? I suspect the font is not correct in the 'outer' instance, but I'm unsure how to check the font of a running X window screenshot demonstrates the problem: Note: I moved this question from serverfault.com - i hope this site is more appropriate

• How to type accented characters in Ubuntu 10.04 with an Apple Aluminum Keyboard

  - by jfmessier

  I installed the latest Ubuntu 10.04 and I used to have the Command, Option or Right-Ctrl keys as compose keys to write accented characters. But I find that under Ubuntu 10.04, the Compose Key is not working, even if I specify the proper Apple Keyboard. Since I cannot work with other keyboard layouts than the plain USA one along with compose keys (I never learned, and I hate, the French layout), this about my only way to input accented characters. I still have to try it with a regular keyboard to see whether there is a difference. Thanks :-)

• Insert escaped characters in seq command separator

  - by dhekir

  How do I insert a string containing escaped characters (\n, \t, etc) as separator for the seq command? The standard format includes a newline character: $ seq 3 1 2 3 But if I try to add something plus a newline, the backslash is escaped and a literal "\n" is used instead: $ seq -s "$\n" 3 1\n2\n3 The same happens using simple quotes, no quotes, or other escaped characters: $ seq -s "\t" 3 1\t2\t3 $ seq -s \t 3 1t2t3 This is not the standard behavior for commands such as echo, so I'm a bit confused here... Edit: Ideally, I'd like a somewhat portable solution (that works in tsch as well as bash, for instance), and without resorting to Perl or other languages.

• I can see markup characters in vim `:help`

  - by Relax

  I just created a .txt file inside .vim/doc for documenting one little function of my .vimrc, ran :helptags ~/.vim/doc and apparently the whole vim help system went wild. Now, if I open for example :help help, I see things like: This also works together with other characters, for example to find help for CTRL-V in Insert mode: > :help i^V < (notice the < and characters). I can also see the ~ at the end of headlines and the modeline at the end of the help page (thinks like vim:tw=78:ts=8:ft=help:norl:). I have no idea about what happens or how to fix it. Any clue? Thanks in advance!

• perl regex escape characters

  - by freshWoWer

  I have heard perl is a good language at doing regex but i am a bit confused at the characters that requires escaping I tested the code on http://regexlib.com/RETester.aspx and got the result I want //home/dev/abc/code/hello/world.cpp#1 //home/dev/((.*?)/[^/]+).*# Match $1 $2 //home/dev/abc/code/hello/world.cpp# abc/code abc However, I am not quite sure how do i translate this to perl code I tried, \/\/home\/dev\/\(\(\.\*\?\)\/\[\^\/\]\+\)\.\*\# and \/\/home\/dev\/((.*?)\/[^\/]+).*\# and both failed Don't you think the escaping makes the regex very unreadable? Am i using something wrong?

• Why do the Escape and Enter keys not always do the right thing in dialog boxes?

  - by Michael Goldshteyn

  Why is it that when a dialog pops up, the Escape key doesn't always cancel it and the Enter key doesn't always press the default button? Shouldn't this be a standard across all dialog boxes in all applications? I have gotten into the habit of pressing Escape to cancel a dialog and Enter to confirm it, but applications (and especially KDE, GNOME and Unity in many many cases) seem to ignore my wishes. What is the problem? Is consitency too much to ask?

• How to escape % in roxygen literate programming?

  - by Karsten W.

  The default value of a parameter of my function contains a "%". This seems to be a problem for roxygen, it produces a lot of warnings and R CMD check fails when trying to build latex documentation. How can I make this function (and its documentation) work? Using %% or \% instead of % does not help. #' Test escape \% from in-source documentation (roxygen). #' #' What happens when parameters contain special latex characters? #' #' @param x unsuspicious parameter #' @param format sprintf format string (default "\%5.0f") #' #' @return formatted string #' @export #' @author Karsten Weinert testroxy <- function(x, format = "%5.0f") { sprintf(format,x) }

• Objective C HTML escape/unescape

  - by Squeegy

  Wondering if there is an easy way to do a simple HTML escape/unescape in Objective C.

Is there any methods in Cocoa Touch/UIKit to do this?

• How to escape HAML for Javascript in Sinatra

  - by viatropos

  I would like to return a list/combobox from an ajax request ("Which on of these do you like?" type thing). I would like to write that little snippet in HAML, which converts it to HTML, but when I do, the page goes blank. I'm assuming this is because the HTML isn't escaped. Is there a way to escape HAML so I can do $("#mydiv").html(response);? Here's the method: post "/something" do # process... haml :"partials/_select", :layout => false, :locals => {:collection => choices} end ... the haml template: %select - collection.each do |item| %option{:value => item.to_s}= item.to_s ... and the javascript: success: function(responseText, statusText, xhr, $form) { $(".dialog_content").append(responseText); } I have tried the sinatra_more plugin and the escape_javascript method, but there's problems with the haml buffer in sinatra. Any ideas?

• Java doesn't work with regex \s, says: invalid escape sequence

  - by Jayomat

  hi, I want to replace all whitespace characters in a string with a "+" and all "ß" with "ss"... it works well for "ß", but somehow eclipse won't let me use \s for a whitespace.. I tried "\t" instead, but it doesn't work either.. I get the following error: Invalid escape sequence (valid ones are \b \t \n \f \r \" \' \ ) this is my code: try { String temp1 = from.getText().toString(); start_from = temp1.replaceAll("ß", "ss"); start_from = start_from.replaceAll("\s", "+"); } why doesn't it work? is it a problem with android, eclipse or what? thanks in advance!

• Escape characters during paste in vim

  - by Michael Anderson

  I copy stuff from output buffers into C++ code I'm working on in vim. Often this output gets stuck into strings. And it'd be nice to be able to escape all the control characters automatically rather than going back and hand editing the pasted fragment. As an example I might copy something like this: error in file "foo.dat" And need to put it into something like this std::string expected_error = "error in file \"foo.dat\"" I'm thinking it might be possible to apply a replace function to the body of the last paste using the start and end marks of the last paste, but I'm not sure how to make it fly.

• How to escape simple SQL queries in C# for SqlServer

  - by sri

  I use an API that expects a SQL string. I take a user input, escape it and pass it along to the API. The user input is quiet simple. It asks for column values. Like so: string name = userInput.Value; Then I construct a SQL query: string sql = string.Format("SELECT * FROM SOME_TABLE WHERE Name = '{0}'", name.replace("'", "''")); Is this safe enough? If it isn't, is there a simple library function that make column values safe: string sql = string.Format("SELECT * FROM SOME_TABLE WHERE Name = '{0}'", SqlSafeColumnValue(name)); The API uses SQLServer as the database. Thanks.

• Show them the default, and allow them to press escape or Ctrl-Z

  - by cf_PhillipSenn

  I have a table cell, and when the user clicks on it, I replace the contents of the table cell with an input tag with the current contents as the default. But I don't like it's behavior because there's a chance that the user can delete the contexts on the input simply by clicking on it a second time. $('.LastName').live('click', function() { var myText = $(this).text(); $(this).empty().append('<input name="LastName" id="LastName" value="' + myText + '" />'); document.myForm.LastName.focus(); }); Q: How do I give the user a default, plus allow them to press the escape key or Ctrl-Z while in the middle of an edit?

• How do you escape parentheses in a Binding indexer

  - by Chris S

  I have the following XAML: <Grid x:Name="LayoutRoot" Background="White" DataContext="{Binding Source={StaticResource MyDataKey}}"> <TextBox Name="_myId" Text="{Binding MyDictionary[(Textbox.Name)]" /> </Grid> But it thinks the key in my dictionary is called "(Textbox.Name)", instead of "_myId". The format below works, where I have a property in my class called "_myId": <TextBox Name="_myId" Text="{Binding (Textbox.Name)" /> I've tried using ^ and \ to escape the brackets. Is this syntax supported? I'm trying to avoid duplication of the name in two attributes.

• Scite Lua - escaping right bracket in regex?

  - by ~sd-imi

  Hi all, Bumped into a somewhat weird problem... I want to turn the string: a\left(b_{d}\right) into a \left( b_{d} \right) in Scite using a Lua script. So, I made the following Lua script for Scite: function SpaceTexEquations() editor:BeginUndoAction() local sel = editor:GetSelText() local cln3 = string.gsub(sel, "\\left(", " \\left( ") local cln4 = string.gsub(cln3, "\\right)", " \\right) ") editor:ReplaceSel(cln4) editor:EndUndoAction() end The cln3 line works fine, however, cln4 crashes with: /home/user/sciteLuaFunctions.lua:49: invalid pattern capture >Lua: error occurred while processing command I think this is because bracket characters () are reserved characters in Lua; but then, how come the cln3 line works without escaping? By the way I also tried: -- using backslash \ as escape char: local cln4 = string.gsub(cln3, "\\right\)", " \\right) ") -- crashes all the same -- using percentage sign % as escape chare local cln4 = string.gsub(cln3, "\\right%)", " \\right) ") -- does not crash, but does not match either Could anyone tell me what would be the correct way to do this? Thanks, Cheers!
