Just created a markdown cell in Jupyter using some equations, and some of them using \mathscr to have like "math" fonts. When I run the kernel containing the equations everything is ok, however when I click the option to Download as PDF via LaTex, I'm getting the error below:
! Undefined control sequence.
l.300 [\mathscr
{L}({\bf{y}}|\beta, \sigma^2, {\bf{X}}) = (2\pi\sigma^2)^{-...
?
! Emergency stop.
l.300 [\mathscr
{L}({\bf{y}}|\beta, \sigma^2, {\bf{X}}) = (2\pi\sigma^2)^{-...
If I remove the \mathscr part everything can be exported with no issues (excepting some convertion problems for special characters), however, I wanted to know ho to solve it. I've been reading and it looks like the nbconvert configuration file can be modified to solve this, but I couldn't find the mentioned file and the exact way to modify it
Thanks for your help
I think the problem is with absent \usepackage{mathrsfs} directive in an intermediate .tex-file.
So you have a several ways to overcome it.
If you face with this problem occasianaly you could the following:
download the .tex-file instead pdf;
manually insert to \usepackage{mathrsfs} to it.
before the first \usepackage for example;
run something like
xelatex file.tex to finally convert to pdf.
If you will do it often, you could try to edit appropriate jinja-template.
At first, find the place where nbconvert was installed. For example with pip: pip show nbconvert. Imagine the path is /home/i/.local/lib/python3.5/site-packages
Then the template would be at /home/i/.local/lib/python3.5/site-packages/nbconvert/templates/latex/base.tplx.
And again: just add \usepackage{mathrsfs} right after ((* block packages *)).
Voila -- the problem should gone.
At the end you have the third option -- you can create your own template from scratch and use it with nbconvert. I don't think it's very convenient way to solve your problem. You could read more in the documentation: http://nbconvert.readthedocs.io/en/latest/customizing.html
I have one Rails application and all files are in erb format. Is there any quick way to convert whole application's erb file to haml.. without any conflict.
And also would like to know for the Reverse..
Thanks in advance. :)
For erb-to-haml
You can use from the command line html2haml
html2haml your_erb_file new_haml_file
If you want to convert all your files in one go, look at this article : http://shifteleven.com/articles/2008/06/08/converting-erb-to-haml-snippet
erb2haml gem will do the trick.. have a look to https://github.com/dhl/erb2haml
For haml-to-erb
I recommend you HAML2ERB service . It's really cool and generates valid ERB/HTML code! Tested on big HAML views (over 800 lines of markup) from the real production app. Project active :)
have a look to this also http://makandracards.com/makandra/544-convert-haml-to-erb
While it is easy enough to set the language for a given (open) file in Sublime Text, I'm wondering if there is any way that I can tell the editor in advance that anything called "Guardfile" should be highlighted like it's Ruby code. Does anyone know how to do this?
The plugins recommended in the comments by Brian both do the job nicely:
ApplySyntax
SyntaxFromFileName
Update:
I couldn't get SyntaxFromFileName to match any of my regex for some reason. On the other hand, DetectSyntax comes with syntax highlight for the Guardfile built in.
Update2:
DetectSyntax has been renamed to ApplySyntax
Putting the following at the top of said file also works
#!/usr/bin/env ruby
I am using ghostscript to print a pdf by command line arguments in c#. but it shows the printed document's name as ghostScript output. I want to change it to a custom name(as letter's name). I know in command line parameters, it does not allow to change it. please help.
I'm sorry, I really don't understand what you're asking. You specify where Ghostscript should write it's output using the "-o" or "-sOutputfile=" command line parameters. The name of the input file does not influence the output file.
Unless you are using something like ps2pdf.....
If you can clarify what you are trying to do, I or someone else can likely help.

When I'm in an html.erb file, I get no snipMate snippets.
I would like both HTML and Ruby, or just HTML would be fine,
How would I do this?
Would I need to write a set of snippets?
If so, is there a way of pulling in existing snippets without copying them?
Is there a way of telling vim to go into html mode when it sees .html erb?
You can use an autocmd to set the filetype to html when opening a ".html.erb" file. This could have unwanted side effects for plugins that work for ".erb" files.
autocmd BufNewFile,BufRead *.html.erb set filetype=html
You can also load more than one set of snippets by using a dotted filetype:
autocmd BufNewFile,BufRead *.html.erb set filetype=html.eruby
See :help snippet-syntax in the snipMate help for more info.
Snippets are stored in directory called snippets somewhere in your ~/.vim folder.
If you look there, there is usually one file per filetype, there is a c.snippets, a ruby.snippets, so it seems what you have to do is to create an erb.snippets there with what you want.
Eventually you could copy the content of ruby.snippets and html.snippets into your new erb.snippets.
Alternatively you can search on github, some people have posted their own erb.snippets configuration. For example, there is a nice collection there :
https://github.com/scrooloose/snipmate-snippets
The best thing would to try first to open a snippet file and look at the syntax, it is pretty easy to create your own snippet depending on what you use the most.
I am currently on a promoting tour for UltiSnips on StackOverflow. UltiSnips supports extending other file types, your erb.snippets would look like this:
extends html, ruby, rails
snippet temp "A snippet only in Erb"
erb rules ${1}
endsnippet
A conversion script for snipMate snippets is shipped with UltiSnips, so switching is easy.
I used the autocommand method to the set the filetype, but then I got html syntax errors for things like this:
<%= image_tag("logo.png", :alt => "Sample App", :class => "round") %>
The last two angle brackets would be highlighted in red, which drove me bonkers. So, I created a symlink called eruby.snippets that points to html.snippets. That worked like a champ and now I don't have to make changes in two places. I also have an eruby-rails snippet directory for non-html eruby snippets.
This is on a Mac OS X system. Note that an alias won't work. You need to hit the terminal and use the ln command. Not sure about doing this on a Windoze system.
You can assign multiple snippets scopes to a single filetype. (I've found that altering the filetype tends to break some syntax highlighting).
You can check that the filetype for erb files is indeed 'eruby' with:
:set filetype?
If you're using the maintained fork of snipmate, it looks like you'll want both the eruby.snippets and eruby-rails.snippets from the snipmate-snippets repository (owned by honza, but I don't have enough reputation to link to it here) (see the INSTALL section of the snipmate README for proper setup).
If you are using the maintained fork, I believe setting g:snipMate.scope_aliases in your .vimrc with the following will work for your example:
let g:snipMate = {}
let g:snipMate.scope_aliases = {}
let g:snipMate.scope_aliases['eruby'] = 'eruby,eruby-rails'
I've added a pull request to snipmate to have their documentation updated.
Jumping on the UltiSnips bandwagon after trying SnipMate for a while. Like SirVer mentioned, having the html, ruby, etc snippets available within an *.erb file was as simple as adding the extend line to the eruby.snippets file.
With the original snipMate plugin, create a file ~/.vim/ftplugin/erb_snippets.vim and put the following into it:
silent call ExtractSnipsFile(g:snippets_dir . 'html.snippets', &l:filetype)
silent call ExtractSnipsFile(g:snippets_dir . 'ruby.snippets', &l:filetype)
