Atom editor: indentation adding extra unwanted spaces - editor

When hitting enter in Atom editor for python code the cursor at the new line adds two extra spaces. So it doesn't end up where it should, i.e. two spaces in as in the rest of the code.
I have already followed the suggestions mentioned here, i.e. tablength=2, softtab with auto mode: How to change new line indentation in atom editor?
In vim it seems this is set by the shiftwidth keyword (i.e. =4 means same problem as above, =2 means it works). I couldn't find this keyword for Atom though.

Trix formatting rules

When users paste items from MS word, for example numbered list or bullet points Trix leaves the symbols in, but does not use the default stye rules. eg See below. Note the indenting
I am wanting to replace pasted bulletpoints with '<li>' tags since that is how the browser, or just adds the default style rules to the text.
As a workaround I was thinking that using Javascript/coffee script to replace all incidents of '•' to <li> during a paste command using onPaste='' However this is problematic, since the implementation could cause unforeseen effects.
Another way might be to create a regex expression, to remove the sybols and do It JIT while pasting.
Any other suggestions would be welcome in achieving this.
Edit
/\d\.\s+|[a-z]\)\s+|•\s+|[A-Z]\.\s+|[IVX]+\.\s+[•].\s/g
This regex expression can find Numbered list and a simple replace on the pasted string, will allow for the desired results.

How can I expand Sublime's language syntax understanding to incorporate custom syntax?

I know that sounds vague. Basically I just want Sublime to highlight custom syntax (color the text), just like it does with native syntax.
I am using Sublime to write LaTeX code. For those that don't know, LaTeX equations are typically enclosed by \[ \], e.g.
\[ E = m c^2 \]
Sublime understands that syntax and colors the enclosing code appropriately.
However, I use my custom defined command, \eq{ ... }, which wraps the \[ \] functionality (so I can globally change some settings by just redefining the \eq definition). e.g.
\eq{ E = m c^2 }
I don't know anything about Sublime under the hood beyond basic key bindings. I want to expand Sublime's understanding of syntax to incorporate my custom command without wasting a ton of time digging through tutorials and such.
Since you are mainly interested in the result and not in the reasoning, I will try to be as straight forward as I can.
The LaTeX syntax of Sublime Text will change in release 3119 and I would recommend to use that, if you want to change something.
Just download it from https://github.com/sublimehq/Packages and put the LaTeX folder into the folder, which opens when you select Preferences >> Browse Packages... in the Sublime Text menu.
Afterwards open the file LaTeX.sublime-syntax and search for ensuremath (LaTeX.sublime-syntax#L498). Duplicate that part (everything with a higher indent) and change the command to the command you wish, e.g. in your example this would be - match: '((\\)eq)(\{)'.
Aside the new syntax removes the highlighting of math environments as strings, because this has lead to several problems.
I made a small entry in the LaTeXTools wiki to explain, how you restore the highlight.

Howto disable hyphenation for typewriter text in doxygen?

I found out, that doxygen add hyphenation hints for latex when outputting text of "\c" command, like:
{\ttfamily on\-Ready\-State\-Change\-Listener}
I want to disable this behavior (so onReadyStateChangeListener won't be hyphenated). Is that possible and how?
No this is not possible. Without hyphenation hints LaTeX will often run long identifiers off the page and into the margin, which is the reason why they were introduced.
If you really want to get rid of it have a look at the function filterLatexString() in src/utils.cpp and remove the if in the default case at the end of the function.
I found this is possible in Doxygen 1.8.9.1, using a small workaround job.
Create a custom header.tex file for use with Doxygen. (Instructions)
Find the line in the header.tex file that starts \newcommand{\+}. If you don't find that text, insert an empty line towards the top of the document.
Replace that line with the following text:
\newcommand{\+}{}
Use the header.tex file with your Doxygen output (Instructions)
This effectively disables all of the hyphenation marks that Doxygen adds to the
words.
NOTES: This is for words with \+ added (e.g. D\+O\+X\+Y\+G\+E\+N). It may work for \- if you just substitute the minus sign into the steps above, but I have not verified that.
I found some itentifiers to still be hyphenated after applying this, but in more reasonable places.
Also, do watch out for text running into the margins, as noted by #doxygen.

Tex command which affects the next complete word

Is it possible to have a TeX command which will take the whole next word (or the next letters up to but not including the next punctuation symbol) as an argument and not only the next letter or {} group?
I’d like to have a \caps command on certain acronyms but don’t want to type curly brackets over and over.
First of all create your command, for example
\def\capsimpl#1{{\sc #1}}% Your main macro
The solution to catch a space or punctuation:
\catcode`\#=11
\def\addtopunct#1{\expandafter\let\csname punct#\meaning#1\endcsname\let}
\addtopunct{ }
\addtopunct{.} \addtopunct{,} \addtopunct{?}
\addtopunct{!} \addtopunct{;} \addtopunct{:}
\newtoks\capsarg
\def\caps{\capsarg{}\futurelet\punctlet\capsx}
\def\capsx{\expandafter\ifx\csname punct#\meaning\punctlet\endcsname\let
\expandafter\capsend
\else \expandafter\continuecaps\fi}
\def\capsend{\expandafter\capsimpl\expandafter{\the\capsarg}}
\def\continuecaps#1{\capsarg=\expandafter{\the\capsarg#1}\futurelet\punctlet\capsx}
\catcode`\#=12
#Debilski - I wrote something similar to your active * code for the acronyms in my thesis. I activated < and then \def<#1> to print the acronym, as well as the expansion if it's the first time it's encountered. I also went a bit off the deep end by allowing defining the expansions in-line and using the .aux files to send the expansions "back in time" if they're used before they're declared, or to report errors if an acronym is never declared.
Overall, it seemed like it would be a good idea at the time - I rarely needed < to be catcode 12 in my actual text (since all my macros were in a separate .sty file), and I made it behave in math mode, so I couldn't foresee any difficulties. But boy was it brittle... I don't know how many times I accidentally broke my build by changing something seemingly unrelated. So all that to say, be very careful activating characters that are even remotely commonly-used.
On the other hand, with XeTeX and higher unicode characters, it's probably a lot safer, and there are generally easy ways to type these extra characters, such as making a multi (or compose) key (I usually map either numlock or one of the windows keys to this), so that e.g. multi-!-! produces ¡). Or if you're running in emacs, you can use C-\ to switch into TeX input mode briefly to insert unicode by typing the TeX command for it (though this is a pain for actually typing TeX documents, since it intercepts your actual \'s, and please please don't try defining your own escape character!)
Regarding whitespace after commands: see package xspace, and TeX FAQ item Commands gobble following space.
Now why this is very difficult: as you noted yourself, things like that can only be done by changing catcodes, it seems. Catcodes are assigned to characters when TeX reads them, and TeX reads one line at a time, so you can not do anything with other spaces on the same line, IMHO. There might be a way around this, but I do not see it.
Dangerous code below!
This code will do what you want only at the end of the line, so if what you want is more "fluent" typing without brackets, but you are willing to hit 'return' after each acronym (and not run any auto-indent later), you can use this:
\def\caps{\begingroup\catcode`^^20 =11\mcaps}
\def\mcaps#1{\def\next##1 {\sc #1##1\catcode`^^20 =10\endgroup\ }\next}
One solution might be setting another character as active and using this one for escaping. This does not remove the need for a closing character but avoids typing the \caps macro, thus making it overall easier to type.
Therefore under very special circumstances, the following works.
\catcode`\*=\active
\def*#1*{\textsc{\MakeTextLowercase{#1}}}
Now follows an *Acronym*.
Unfortunately, this makes uses of \section*{} impossible without additional macro definitions.
In Xetex, it seems to be possible to exploit unicode characters for this, so one could define
\catcode`\•=\active
\def•#1•{\textsc{\MakeTextLowercase{#1}}}
Now follows an •Acronym•.
Which should reduce the effects on other commands but of course needs to have the character ‘•’ mapped to the keyboard somewhere to be of use.

LaTeX: Prevent line break in a span of text

How can I prevent LaTeX from inserting linebreaks in my \texttt{...} or \url{...} text regions? There's no spaces inside I can replace with ~, it's just breaking on symbols.
Update: I don't want to cause line overflows, I'd just rather LaTeX insert linebreaks before these regions rather than inside them.
\mbox is the simplest answer. Regarding the update:
TeX prefers overlong lines to adding too much space between words on a line; I think the idea is that you will notice the lines that extend into the margin (and the black boxes it inserts after such lines), and will have a chance to revise the contents, whereas if there was too much space, you might not notice it.
Use \sloppy or \begin{sloppypar}...\end{sloppypar} to adjust this behavior, at least a little. Another possibility is \raggedright (or \begin{raggedright}...\end{raggedright}).
Surround it with an \mbox{}
Also, if you have two subsequent words in regular text and you want to avoid a line break between them, you can use the ~ character.
For example:
As we can see in Fig.~\ref{BlaBla}, there is nothing interesting to see. A~better place..
This can ensure that you don't have a line starting with a figure number (without the Fig. part) or with an uppercase A.
Use \nolinebreak
\nolinebreak[number]
The \nolinebreak command prevents LaTeX from
breaking the current line at the point of the command. With the
optional argument, number, you can convert the \nolinebreak command
from a demand to a request. The number must be a number from 0 to 4.
The higher the number, the more insistent the request is.
