What you’ve got there is an example of Friedl’s “unrolled loop” technique, but you seem to have some confusion about how to express it as a string literal. Here’s how it should look to the regex compiler: “[^”\\]*(?:\\.[^”\\]*)*” The initial “[^”\\]* matches a quotation mark followed by zero or more of any characters other than … Read more
Sorry, you can’t do that. It only works for simple expressions. See here.
Both are equal and what you use is entirely your preference. As far as the char vs string thing is concerned, refer to the Zen of Python, (PEP 20 or import this) Special cases aren’t special enough to break the rules. A string of length 1 is not special enough to have a dedicated char … Read more
A slightly better way, avoiding the possible security implications of using eval, is declare “$var=$val” Note that declare is a synonym for typeset in bash. The typeset command is more widely supported (ksh and zsh also use it): typeset “$var=$val” In modern versions of bash, one should use a nameref. declare -n var=x x=$val It’s … Read more
Wikipedia does have an API. So does Wikiquote: http://en.wikiquote.org/w/api.php maybe give that a try…
I had recently similar problem and the only way to solve it was to use plain old HTML codes for single (') and double quotes ("). Source code was total mess of course but it worked. Try <a id=”aShowHide” onclick=’ToggleDisplay("<%# DataBinder.Eval(Container.DataItem, “JobCode”) %>");’>Show/Hide</a> or <a id=”aShowHide” onclick=’ToggleDisplay('<%# DataBinder.Eval(Container.DataItem, “JobCode”) %>');’>Show/Hide</a>
The only reason you might need “”” instead of ”’ (or vice versa) is if the string itself contains a triple quote. s1 = ”’This string contains “”” so use triple-single-quotes.”’ s2 = “””This string contains ”’ so use triple-double-quotes.””” If a string contains both triple-single-quotes and triple-double-quotes then you will have to escape one … Read more
The call command has this functionality built in. To quote the help for call: Substitution of batch parameters (%n) has been enhanced. You can now use the following optional syntax: %~1 – expands %1 removing any surrounding quotes (“) Here is a primitive example: @echo off setlocal set mystring=”this is some quoted text” echo mystring=%mystring% … Read more
You need to escape the backtick, but also escape the backslash: $ touch 1\` $ /bin/sh -c “ls 1\\\`” 1` The reason you have to escape it “twice” is because you’re entering this command in an environment (such as a shell script) that interprets the double-quoted string once. It then gets interpreted again by the … Read more
You might consider using an array for the args, something like this: args=( “$f1” “$f2” ) ls “${args[@]}” (The problem you’re hitting at the moment is that once interpolation has happened there’s no difference between intra- and inter- filename spaces.)
