You can use match on the string containing the line breaks, and the number of elements in that array should correspond to the number of line breaks. enteredText = textareaVariableName.val(); numberOfLineBreaks = (enteredText.match(/\n/g)||[]).length; characterCount = enteredText.length + numberOfLineBreaks; /\n/g is a regular expression meaning ‘look for the character \n (line break), and do it globally … Read more
After digging a bit through the perlre docs a bit, I’ll present my best suggestion so far that seems to work pretty good. Perl 5.10 added the \R character class as a generalized linebreak: $line =~ s/\R//g; It’s the same as: (?>\x0D\x0A?|[\x0A-\x0C\x85\x{2028}\x{2029}]) I’ll keep this question open a while yet, just to see if there’s … Read more
​ is the HTML entity for a unicode character called the zero-width space (ZWSP). “In HTML pages, this space can be used as a potential line-break in long words as an alternative to the <wbr> tag.”- Zero-width space – Wikipedia The <wbr> tag also works, as mentioned by Aaron’s answer. I think I prefer the … Read more
(defun remove-dos-eol () “Do not show ^M in files containing mixed UNIX and DOS line endings.” (interactive) (setq buffer-display-table (make-display-table)) (aset buffer-display-table ?\^M [])) Solution by Johan Bockgård. I found it here.
You should use the url package: \usepackage{url} … \url{http://long.url.com/… …/stuff} and it will break it for you at an appropriate place.
You can always extend a logical line across multiple physical lines with parentheses: answer = ( ‘Ten for that? You must be mad!’ if does_not_haggle(brian) else “It’s worth ten if it’s worth a shekel.”) This is called implicit line joining. The above uses the PEP8 everything-indented-one-step-more style (called a hanging indent). You can also indent … Read more
Line break accepts an optional argument in brackets, a vertical length: line 1 \\[4in] line 2 To make this more scalable with respect to font size, you can use other lengths, such as \\[3\baselineskip], or \\[3ex].
PEP 8 recommends using parenthesis so that you don’t need \, and gently suggests breaking before binary operators instead of after them. Thus, the preferred way of formatting you code is like this: my_var = (somethinglikethis .where(we=do_things) .where(we=domore) .where(we=everdomore)) The two relevant passages are this one from the Maximum Line Length section: The preferred way … Read more
