# Sandbox

Use this page to experiment with wiki markup. 

## Bulleted lists ##
Nested bulleted list with two spaces for the second level of indentation and four spaces for the fourth:

* a
  * a.b
      * a.b.c
  * a.v
* z  

That list looks correct in the preview and correct in the final presentation.

Another list where there are two spaces for each level of indentation:

* a
  * a.b
    * a.b.c
  * a.v
* z  

Note that that list looks messed up in the preview, but correct in the final presentation.

and one where there are four spaces for each level of indentation:

* a
    * a.b
        * a.b.c
    * a.v
* z  

That list looks correct in both the preview and the final presentation.

##Outlines

Only two levels of indentation are shown in the "How to Format Text" box, but in reality, more are available:

###Third level of indentation
####Fourth level of indentation
#####Fifth level of indentation

However, the fifth level looks smaller than body text.

##Code

We need a way to present code as-is, so we want to be able to turn off wiki formatting for a block. The "code" markup (a pair of backticks) doesn't do the job.

###Backticks
Code sample (note that the format differs between preview mode and final presentation):

`
if (a)
    b
else
    c
`

###Triple backticks

This section is "fenced off" by triple backticks (see [GitHub Flavored Markdown](https://help.github.com/articles/github-flavored-markdown)):

```
if (a)
    b
else
    c
```

but the formatting is not preserved.

###Blockquote

The blockquote markup doesn't do the job either, since again the format differs between preview mode and final presentation:

>>if (a)
>>    b
>>else
>>    c

###XML-style blockquote tag
Here's an attempt to use an XML-style blockquote tag:

<blockquote>
if (a)
    b
else
    c
</blockquote>

The blockquote tag disappears altogether, but does not prevent the text it surrounds from being reformatted.

##Escaping characters

We need ways of escaping various characters:

###Underscore
Mention a name that contains a single underscore:

a_b

It appears correctly. But mention a name that contains an underscore twice:

a_b   a_b

It appears as:

ab ab 

where the first b and the second a are italicized. 

Solution: Use a backslash in front of each underscore:

a\\\_b a\\\_b

to produce this output:

a\_b a\_b

###Parenthesis

Say that I want to write this, but in a help section, so I don't want to trigger interpretation as an actual link. Here, I've included spaces to throw off interpretation, but I want to be able to accomplish that through escape sequences instead.

[ t e x t ] ( h t t p : / / example . com )

Solution: put a backslash before the open-square-bracket and before the open-parenthesis and close-parenthesis. (Putting a backslash before the close-square-bracket is optional.)

\\[text\\]\\(http://example.com\\)

Output:

\[text\]\(http://example.com\)

##Bookmarklet code
First bookmarklet test (which succeeds in both preview and presentation modes):

[test][1]

  [1]: javascript:var%20p=Math.floor((Math.random()*100)+1);location.href=%22http://tatoeba.org/eng/sentences/show_all_in/epo/und/eng/indifferent/page:%22+p;


Second bookmarklet test (which succeeds only in preview mode):

[test 2a](javascript:var%20u%20=%20%22%22;var%20e=window.prompt%28%22Enter%20URL%20or%20number%20of%22+%22%20sentence%20to%20link%20to%20this%20one%22,%22%22%29;if%28e!=null%29{var%20r=/%28http:\/\/%5B^\/%5D+\/%5Ba-z%5D{3}\/%29?%28sentences\/show\/%29?%28%5B1-9%5D%5B0-9%5D%29%28#.%29?/;var%20em=e.match%28r%29;if%28em!=null%29{var%20h=location.href;var%20hm=h.match%28r%29;u=hm%5B1%5D+%22links/add/%22+hm%5B3%5D+%22/%22+em%5B3%5D;location.href=u;}else{alert%28%22Invalid%20input.%22%29};})

Third bookmarklet test (which succeeds only in preview mode; in presentation mode it points to http://en.wiki.tatoeba.org/articles/show/sandbox):
 
[test 2][2]

  [2]: 
javascript:var%20u%20=%20%22%22;var%20e=window.prompt%28%22Enter%20URL%20or%20number%20of%22+%22%20sentence%20to%20link%20to%20this%20one%22,%22%22%29;if%28e!=null%29{var%20r=/%28http:\/\/%5B^\/%5D+\/%5Ba-z%5D{3}\/%29?%28sentences\/show\/%29?%28%5B1-9%5D%5B0-9%5D%29%28#.%29?/;var%20em=e.match%28r%29;if%28em!=null%29{var%20h=location.href;var%20hm=h.match%28r%29;u=hm%5B1%5D+%22links/add/%22+hm%5B3%5D+%22/%22+em%5B3%5D;location.href=u;}else{alert%28%22Invalid%20input.%22%29};}

Fourth bookmarklet test (which fails in both preview mode and presentation mode; in presentation mode it points to http://en.wiki.tatoeba.org/articles/show/sandbox):

[test 3][3]

  [3]: 
javascript:var%20u%20=%20"";var%20e=window.prompt("Enter%20URL%20or%20number%20of" +"%20sentence%20to%20link%20to%20this%20one","");if(e!=null){var%20r=/(http:\/\/[^\/]+\/[a-z]{3}\/)?(sentences\/show\/)?([1-9][0-9])(#.)?/;var%20em=e.match(r);if(em!=null){var%20h=location.href;var%20hm=h.match(r);u=hm1+"links/add/"+hm[3]+"/"+em[3];location.href=u;}else{alert("Invalid%20input.")};}

Fifth bookmarklet test, in which I use backslashes to escape all backslashes, open-square-brackets, close-square-brackets-, open-parentheses, and close-parentheses:

javascript:var%20u%20=%20"";var%20e=window.prompt\("Enter%20URL%20or%20number%20of%20sentence%20to%20link%20to%20this%20one",""\);if\(e!=null\){var%20r=/\(http:\\/\\/\[^\\/\]+\\/\[a-z\]{3}\\/\)?\(sentences\\/show\\/\)?\(\[1-9\]\[0-9\]*\)\(#.*\)?/;var%20em=e.match\(r\);if\(em!=null\){var%20h=location.href;var%20hm=h.match\(r\);u=hm\[1\]+"links/add/"+hm\[3\]+"/"+em\[3\];location.href=u;}else{alert\("Invalid%20input."\)};}
