I am using the Vim-R-plugin to edit files containing markdown and R-code blocks such that the files can be complied using knitr. The filetype is: RMD. I have enabled spell checking. How can I disable the spell checking within the code blocks?
Spell checking is attached to certain syntax groups. Find the :syn region that covers the R code blocks, and append / edit in contains=#NoSpell.
Instead of trying to get the #NoSpell working by region, my approach is to toggle between languages.
I work in three languages which are set up to toggle with a function key where I include "nospell". This makes turning spellchecking on and off as easy as pressingt F7. When coding and writing nospell is turned on, when finalizing the edits I toggle to the appropriate language.
In fact, I find spellchecks in my code to be a plus. I make mistakes in the comment sections too, sometimes even in variable names/plot lables etc. This way you have a quick last check of all language items that are going to be visible .
I got this to work on OS X by editing the ~/.vim/syntax/R.vim and doing a search and replace of all instances of #Spell to #NoSpell. Then restarting vim. All the red underscores were gone from the code chunks but were still in the rest of the the rmarkdown.
Interestingly this has not effected the spell checking in pure R documents that have a .R extension, so I having thought I understood what I was doing perhaps I have to admit I don't fully. But at least it has turned off spell checking of the code chunks in rmarkdown (Rmd) documents while leaving it still working elsewhere in the document.

The github repo on which I work with many others contains many python files and about ten jupyter notebooks. 'make html' currently assumes that the markdown JN cells are written in reST, which can produce meaningless and ugly results. Is it possible to configure sphinx (or maybe nbsphinx??) so that readthedocs for the JN markdown cells is rendered using markdown (preferably in the JN flavour)?
There is a website https://gist.github.com/dupuy/1855764 that addresses this problem by discussing constructs that are common to markdown and reST, but the document is at least 10 years old. For example, it lacks the "click here" link construct that works in both markup languages, namely:
[click here](urlname).
There remain in our JNs constructs that do not seem to have a common syntax that produces decent rendering in both markdown and reST, or at least I have not been successful in searching for one. An example (and there may be others) is making nested lists, specially lists without numbers or bullets.
An alternative would be for the JN text cells to be rendered by reST. There is a website https://nbsphinx.readthedocs.io/en/0.8.8/raw-cells.html that explains how to use reST in a JN. I have two problems with that. Firstly, JNs in our environment do not behave as this website explains, and I do not know how to change our environment (configuration files for JNs??) to make them behave in the way claimed by the website. Secondly, our JNs are designed to be used by naive users (even more naive than I am), and so the JN must work when the naive user uses JN in its "out of the box" configuration.
I'm using VS Code and i miss RStudio's ctrl+i to indent lines.
I've read stuff online about LSP and other extensions and formatting with shift+alt+F but all i get is linter.
So, whats the equivalent if is there at all?
Found a solution but there a few things to take note.
First, VSCode notive options are language-agnostic, meaning it can't indent R code 'cause it doesn't understand it. You got to download extensions to make i work.
Extensions required are
Yuki Ueda's R for language support
REditorSupport's R LSP Client
Also, in order to R LSP Client to work, CRAN package {languageserver} is required.
Then, usage. If you're working functions, differently from RStudio in which one can hit ctrl+i and that'd indent that specifically line or selection, this solution works only if one selects the entire function. If you have functions inside another, you gotta indent everything (won't work for just a foo inside another).
In order to create the exam sheets without solution, everything works fine with exams2nops (apart from the logo which is not taken for some reason). I can add the name of the institution, change the title, and setup a non-English language and the date. But if I want to create examsheets with the solutions, then, if I understand correctly, I cannot use anymore exams2nops, but I have to use exams2pdf with template="solution" which does not take into account the institution, the date, the language, nor the title.
Any help?
You are correct that exams2nops() does not provide a version of the PDF with the {solution} environment and the complete answer text. The nops_eval() only provides a HTML report with the correct boxes that needed to be checked.
So to produce a PDF as desired you can run exams2pdf(...) or exams2pdf(..., type = "solution") after setting the same random seed that you set before running exams2nops(). If you want to modify anything like layout/logo/language/etc. in exams2pdf() you have full flexibility but need to do the work yourself. That is you need to come up with a LaTeX template file that looks the way you want. As a starting point you can take solution.tex from the package. The easiest way to get all templates shipped with the package is to run exams_skeleton() and then look at the templates folder.
Background info: exams2nops() also just calls exams2pdf() internally after setting up a suitable LaTeX template file based on the arguments specified by the user.
As already mentioned I'm using the Atom text editor.
I'm currently working on a project written in c++. Of course it is desirable to jump to the definition of a function (in another project file), or other uses of this function (within the project). As far as I know this can be achieved with the packages I'll mention below. I want the package to display me the definition along with the path to the corresponding file which holds the definition and ideally the line where it occurs.
I'll welcome any comments and suggestions on how to solve the below mentioned problem(s) I have with (one of) the packages. Moreover I'm also thankful about pointers to possible solutions or posts concerning my problem(s), or how I can achieve this with another package.
Here is what I found / tried / did so far.
goto
Currently I'm using this package, although it is rather slow and does not show the arguments of the function as e.g. atom-ctags does, but it's the only package which displays me the files I need to see.
It shows me where the function is defined as well as where it is also used. However it does not show me the path to the file corresponding file it refers to.
atom-ctags
I also tried this package, building the tags is quite fast and moreover it show me the path to the file. But this package only lists the .cc files and not the .h files. It appears to me as if it only shows me the other uses but not the definition, which is obviously a problem.
I also tried generating the ctags myself and changing the command options in the settings of the package, unfortunately without any success.
Atoms built-in symbols-view
In order to get this to work, one needs to generate the symbols. This can be, for example, achieved with the symbol-gen package. However, it shows me some of the definitions, but also no .h files. Moreover, jumping to the definition results in a Selected file does not exist., therefore it is not usable at all.
goto-definition
Just for completeness, there is also this package. It does not work for me, since c++ is not supported but maybe others will find it useful.
symbols-plus
Again, for completeness, this should be a replacement for the atom built-in, but when disabling the build-in it does not show me any jump functionality nor is a short cut mentioned.
So, basically, nothing really works well. I have tried Symbol Tree View but it but barely works.
I'm writing all my scripts on .R file using R for mac. It is convenient to me because there are colors to highlight the type of commands.
I have a many comments following the # symbol that are useful when I forget about the meaning of my script but they tend to blur my script so that it gets harder to find a given command line.
Is there a way to hide and show these comments ? (Using the programm I'm currently using or another one). What would you suggest as the best program to write R script ?
Thanks a lot !
RStudio supports code folding. You can standardize your comment blocks so that they are recognized as code blocks.
For example, enter this into your RStudio editor
#=======================================================
# this is a comment block
# more comments here
# comments upon comments
and then press Alt+L to fold, and Alt+Shift+L to unfold.
Try RStudio for mac. One of the greatest code writing environment for R there is.
You can also try Emacs, which is more like old-fashioned command line editor. You can find a good guide here.
