Everything I found online was about removing the trailing whitespace altogether but I'd like to remove it only for text files, in particular .key files.
I tried to modify the config.cson like this:
".text.plain.key":
whitespace:
removeTrailingWhitespace: true
or small variations of it, but I wasn't able to make it work.
If text.plain.key is a valid scope, the correct entry should look like this:
".text.plain.key":
editor:
removeTrailingWhitespace: true

I'd like to retain multiple spaces in the \details{} section's text of an Rd help file, which by default are compressed to one single space.
The result should look like:
Either this is super trivial or impossible. Any ideas out there?
Just add \verb{ } or in roxygen2 ` `, with proper numer of spaces .
I have this in my config.cson:
".java.source":
whitespace:
removeTrailingWhitespace: false
".plain.text":
whitespace:
removeTrailingWhitespace: false
It works for .java files and .txt files. However, I also want it to work for specific file extensions that I don't have a scope name for.
E.g. when I edit a .foobar file, Atom treats it as plain text. However, it still adds a trailing newline. How do I prevent this?
You need to assign a syntax to your custom file type, then your previous configuration will work for them.
Example
"*":
core:
customFileTypes:
"source.js": [
"*.foobar"
]
I'm currently trying to build a chat app, using the official markdown package as well as underscore's escape function, and my template contains something like this:
<span class="message-content">
{{#markdown}}{{text}}{{/markdown}}
</span>
When I grab the text from the chat input box, I try to escape any HTML and then add in line breaks. safeText is then inserted into the database and displayed in the above template.
rawText = $("#chat-input-textbox").val();
safeText = _.escape(rawText).replace(/(?:\r\n|\r|\n)/g, '\n');
The normal stuff like headings, italics, and bold looks okay. However, there are two major problems:
Code escape issue - With the following input:
<script>alert("test")</script>
```
alert('hello');
```
This is _italics_!
Everything looks fine, except the alert('hello'); has become alert('hello'); instead. The <pre> blocks aren't rendering the escaped characters, which makes sense. But the problem is, the underscore JS escape function escapes everything.
SOLVED: Line break Issue - With the following input:
first
second
third
I get first second third being displayed with no line breaks. I understand this could be a markdown thing. Since I believe you need an empty line between paragraphs to get linebreaks in markdown. But having the above behaviour would be the most ideal, anyone know how to do this?
UPDATE Line break issue has been solved by adding an extra \n to my regex. So now I'm making sure that any line break will be represented with at least two \n characters (i.e. \n\n).
You should check the showdown docs and the wiki article they have on the topic.
The marked npm package, which is used by Telescope removes disallowed-tags. These include <script> of course. As the article I linked to above explains, there's still another problem with this:
<a href='javascript:alert("kidding! Im more the world domination kinda guy. Muhahahah")'>
click me for world peace!
</a>
Which isn't prevented by marked. I'd follow the advice of the author and use a HTML sanitation library. Like OWASP's ESAPI or Caja's html-sanitizer. Both of these project's seem outdated dough. I also found a showdown extension for it called showdown-xss-filter. So my advice is to write your own helper, and use showdown-xss-filter.
I am belatedly setting up Aptana to use four spaces instead of tabs. I've made the necessary changes to the preferences so every new tab inserts four spaces.
All the existing tabs remain, however, and so I get Mixed spaces and tab errors. How can you do a Replace all to fix this? I've tried ^t, <TAB> etc but it just searches for these as normal strings. What are the correct ways to specify a space and a tab?
I've found myself in similar situation and copying whole source code and repasting it helped me out. Just do as follow on your source code Ctrl+A, Ctrl+C, then Del whole code and Ctrl+V it again. You will get only spaces if have set it in options like you mentioned above.
There's an option in the refactor source menu to convert between tabs and space-tabs.
This worked for me: Edit > Find/Replace... (CTRL+F), check Regular Expressions, type \t and type 4 spaces (I use 4 spaces for tab).
I'm trying to expand a minified CSS file (don't ask) to make it human readable.
I've managed to get most of the expanding done but I'm stuck at a very weird case that I can't figure out.
I have CSS that looks like this:
.innerRight {
border:0;color:#000;width:auto;padding-top:0;margin:0;
}
a {
color:#000;text-decoration:underline;font-size:12px;
}
p,small,ul,li {
color:#000;font-size:12px;padding:0;
}
I've tried (.+):(.+); as the search and \t\1: \2;\n as the replace. The find RegEx is valid, the only problem is that it matches the entire line of attributes. I've tried the non-greedy character, but I must not be putting it in the right place.
What the above find RegEx matches is:
0: border:0;color:#000;width:auto;padding-top:0;margin:0;
1: color:#000;text-decoration:underline;font-size:12px;
2: color:#000;font-size:12px;padding:0;
While those are technically correct matches, I need it to match border:0;, color:#000;, etc separately for my replace to work.
Try this - use non-greedy matching. This works for me
(.+?):(.+?);
Forget the colon. Just replace all semicolons with ";\n".
In Javascript, for example, you could write:
text = text.replace(/;/gm,";\n");
I would further refine that to address leading-space issues, etc., but this will put every style rule on its own line.
