Two spaces in LaTeX code












3















I have a simple question: does it make any difference whether at some point I have two spaces instead of one in the source code, say after a period? That is, will PdfTeX ever output different things with two codes that, everything else being equal, differ in this:



end of. Sentence


vs.



end of.  Sentence


I am not asking about the difference between having frenchspacing or not, I am really just interested in how multiple spaces in the source code are interpreted.

    As far as I know, the answer is no. In other word: hello world and hello world gives the same output.

  • Edit of above comment: "hello_world" and "hello_ _ _ _world" are the same, except they are put in a "source-code" environment, like verb|...|, lstlisting or minted.

  • No, but one should use Mr.~Smith or {Mr.} Jones when only one space is wanted. Okay, it probably isn't precisely a 2/1 ratio, but it is smaller.

No. Multiple consecutive spaces are gobbled into a single space within the code, unless they are hard coded (like using ~ or - a control space - or via hspace, or ...).



The setting of it might differ, however, depending on the other elements within the line of text. This is because the inter-word spacing can shrink/stretch as the paragraph setting is optimised. Here are some examples that hopefully illustrates this:



enter image description here



documentclass{article}



begin{document}



% Same end-of-sentence/period

This is text. Some more text.



This is text.  Some more text.



This is text.                    Some more text.



hrulefill



% Regular space

This is text. Some more text.



This is text.~Some more text.



hrulefill



medskip



% Stretched inter-word space

parbox{120pt}{This is text. Some more text.}



medskip



parbox{120pt}{This is text. Some more text.}



end{document}

    You might want to be ultra specific and say "multiple consecutive spaces". If something "invisible" (e.g. an index entry) comes between two spaces in the input stream, each space is handled separately, and the output can look quite ragged.

Magento 2 controller redirect on button click in phtml file

Image
0 I want to redirect customer using controller when button is clicked in one of my phtml files. So far I got, controller: public function execute(){ return $this->addToCart(); } public function addToCart(){ // some logic $this->_redirect('checkout/cart/index'); } The above is working fine (redirecting) when you access the controller via URL (www.mydomain.com/batchorder/index/addtocart). And here is my .phtml file: $("#addToCart").click(function(){ let controllerUrl = "<?php echo $block-getUrl('batchorder/index/addtocart'); ?>" $.post(controllerUrl, { "products": JSON.stringify(sideCart.SideCartProducts) }) The post request returns my logic as it should, however, it is not redirecting. Anyone can help? ...
