Combining two commands in a new command in Latex - macros

I am trying to create a new command that will replace text with a blank line to write on. Essentially, the lovechild of, \underline and \phantom if it can be toggled on and off that would be even better but I seem to have a misunderstanding of how macros work in latex.
My crappy code is below
\newcommand{\rmv{}}{\Underline{\phantom{}}}

You're macro needs to know what text you want in the gap, so it needs an argument. The syntax to pass argument to the new macro is
\newcommand\macroname[number of arguments]{use the argument with #1 etc.}
\documentclass{article}
\newif\ifgaps
\gapstrue % comment/uncomment to toggle
\newcommand{\rmv}[1]{%
\ifgaps%
\underline{\phantom{#1}}%
\else%
#1%
\fi%
}
\begin{document}
test \rmv{test} test
\end{document}
(to automatically create two versions of your pdf with and without the gaps, you could use something similar to https://topanswers.xyz/tex?q=583 )

Use matched groups in find and replace dialog of the Matlab script editor

This is a question about the Matlab editor. I have several recurrent texts in my script such as:
e_{pos}=%.3f, e_{vel}=%.3f\n
I want to remove the curly brackets around these terms, so I use the Find/Replace dialog to replace \{(\w+)\} with $1:
But, the editor inserts a literal $1 instead of the matched text (vel or pos). I know some editors use different characters than $ so I also tried \1 and #1 but they did not work either. The documentation does not mention it.
So, is it possible to replace a matched group in the Matlab editor? How can I do it?
Note: I am not asking for the Matlab code to do this, I want to do it in the editor.
Thank you!

how to add different number at end of multi line edit?

Having trouble finding a way to do this, maybe it is not even possible?
In my case, for testing flow of if-statements/user-interaction, am temporarily adding 40 lines of console.log('trigger-fired-1'); throughout our code.
However, to tell them apart would like each to end with a different number, so in this case, numbers one to forty like so:
In the screen recorded gif, to replicate what I am going for, all I did was copy/paste the numbers one to nine. What I really would like is a shortcut key to generate those numbers at the end for me to eliminate that step of typing out each unique number.
Am primarily coding in Visual Studio Code or Sublime Text, and in some cases shortcuts are similar, or at least have same support but for different shortcut keys.
There are a few extensions that allow you to do this:
Text Pastry
Increment Selection
NumberMonger
For Sublime Text, the solution to this problem is the internal Arithmetic command. Something similar may or may not be available in VS Code (possibly with an extension of some sort) but I'm not familiar enough with it to say for sure.
This command allows you to provide an expression of some sort to apply to all of the cursor locations and/or selected text.
By way of demonstration, here's the example you outlined above:
The expression you provide is evaluated once for every selection/caret in the buffer at the time, and the result of the expression is inserted into the buffer (or in the case of selected text, it replaces the selection). Note also that when you invoke this command from the input panel (as in the screen recording) the panel shows you a preview of what the expression output is going to be.
The special variable i references the selection number; selections are numbered starting at 0, so the expression i + 1 has the effect of inserting the selection numbers starting at 1 instead of 0.
The special variable x refers to the text in a particular selection instead. That allows you to select some text and then transform it based on your expression. An example would be to use x * 2 immediately after the above example (make sure all of the selections are still present and wrapping the numbers) to double everything.
You can use both variables at once if you like, as well as anything in the Python math library, for example math.sqrt(i) if you want some really esoteric logs.
The example above shows the command being selected from the command palette interactively, where the expression automatically defaults to the one that you want for your example (i + 1).
If you want to have this as a key binding, you can bind a key to the arithmetic command and provide the expression directly. For example:
{
"keys": ["super+a"],
"command": "arithmetic",
"args": {
"expr": "i+1"
},
},
Try this one ...
its not like sublime
but works g

Replacing a string in Rubymine with a string with newlines

I want to use the Search and Replace dialogue in Rubymine, or something similar to replace something like "Scenario:" with "#Desktop\nScenario"
I'm trying to replace every instance of Scenario: in a large Cucumber test suite with
#desktop
Scenario:
Any best ways to do this?
Update:
Thanks to #ryan2johnson9 comment, I realise there's now an easier option (tested on 2017.3).
By clicking on the "New Line" (or using the shortcut Ctrl+Shift+Enter / Alt+Enter), the input becomes multilines.
Original Answer
In the search and replace box, if you tick the "Regex" option you can do:
Search: "Scenario:"
Replace by: "#desktop\nScenario:"
The only trick is to tick the "Regex" option :)
Rubymine has macros (http://www.jetbrains.com/ruby/webhelp/binding-macros-with-keyboard-shortcuts.html) but I dont think they are powerful enough for this example.
It's possible that you could solve it with some elaborate feature hidden inside Rubymine, but I think it would be a lot easier to do this with a tool like perl/sed from the Terminal. If you are using Windows I assume you could search the net and find a text search/replace tool that fits your need.
In OSX I there are a bunch of Text Substitutions app too.
I would go that route since Rubymines macro tool isnt up to the task.
Here's a cheap and sleazy alternative:
Copy a newline character from between two empty lines in the file being edited. Temporarily add two empty lines if you don't have any.
Set up search/replace and enter the string you want to replace into the search text input box.
Paste the newline you just copied into the replacement text box plus whatever other text you want. You will be able to see the height of the replacement text input box grow vertically by one line due to the newline.
Perform the search/replace.
For this, the use of the Rubymine regex is optional.

Problem writing a snippet containing Emacs Lisp code

I've been trying to make use of a cool feature of YASnippet: write snippets containing embedded Emacs Lisp code. There is a snippet for rst-mode that surrounds the entered text with "=" that is as long as the text such as in
====
Text
====
Based on this snippet, I decided to slightly modify it (with Elisp) so that it comments out these three lines depending on the major mode you are in (I thought that such a snippet would be useful to organize the source code). So I wrote this:
${1:`(insert comment-start)`} ${2:$(make-string (string-width text) ?\-)}
$1 ${2:Text}
$1 ${2:$(make-string (string-width text) ?\-)}
$0
This code works relatively well except for one problem: the indentation of these three lines gets mixed up, depending on the major mode I'm in (e.g., in emacs-lisp-mode, the second and the third lines move more to the right than the first line).
I think the source of the problem might have something to do with what comes after the string ${1: on the first line. If I add a character, I have no problem (i.e., all three lines are correctly aligned at the end of the snippet expansion). If I add a single space after this string, the misalignment problem still continues though.
So my question is: do you know of any way of rewriting this snippet so that this misalignment does not arise? Do you know what's the source of this behaviour?
Cheers,
From Writing snippets:
yas/indent-line
The variable yas/indent-line controls the indenting. It is bound to 'auto by default, which causes your snippet to be indented according to the mode of the buffer it was inserted in.
Another variable yas/also-auto-indent-first-line, when non-nil does exactly that :-).
To use the hard-coded indentation in your snippet template, set this variable to fixed.
To control indentation on a per-snippet basis, see also the directive # expand-env: in Writing Snippets.
For backward compatibility with earlier versions of YASnippet, you can also place a $> in your snippet, an (indent-according-to-mode) will be executed there to indent the line. This only takes effect when yas/indent-line is set to something other than 'auto.
for (${int i = 0}; ${i < 10}; ${++i})
{$>
$0$>
}$>

Getting Emacs fill-paragraph to play nice with javadoc-like comments

I'm writing an Emacs major mode for an APL dialect I use at work. I've gotten
basic font locking to work, and after setting comment-start and
comment-start-skip, comment/uncomment region and fill paragraph also
work.
However, comment blocks often contain javadoc style comments and i
would like fill-paragraph to avoid glueing together lines starting
with such commands.
If I have this (\ instead of javadoc #):
# This is a comment that is long and should be wrapped.
# \arg Description of argument
# \ret Description of return value
M-q gives me:
# This is a comment that is long and
# should be wrapped. \arg Description
# of argument \ret Description of
# return value
But I want:
# This is a comment that is long and
# should be wrapped.
# \arg Description of argument
# \ret Description of return value
I've tried setting up paragraph-start and paragraph-separate to
appropriate values, but fill-paragraph still doesn't work inside a
comment block. If I remove the comment markers, M-q works as I want
to, so the regexp I use for paragraph-start seems to work.
Do I have to write a custom fill-paragraph for my major
mode? cc-mode has one that handles cases like this, but it's really
complex, I'd like to avoid it if possible.
The problem was that the paragraph-start regexp has to match the entire line to work, including the actual comment character. The following elisp works for the example I gave:
(setq paragraph-start "^\\s-*\\#\\s-*\\\\\\(arg\\|ret\\).*$")
Here a page that has an example regexp for php-mode that does this:
http://barelyenough.org/blog/2006/10/nicer-phpdoc-comments/
There's other modes that have less complex functions used for fill-paragraph-function. Browsing through my install, it looks like the ones in ada-mode and make-mode are good examples.
What I do in these cases is open a blank line between the paragraph lines and the argument lines, then use M-q to wrap the paragraph lines, then kill the blank line between them. Not ideal, but it works and is easy enough to record in a macro if you need to repeat it.
