I've just converted my Rails 4 app from Haml to Slim. Everything went well but I can't get plain text emails to work.
I used the haml2slim converter. It automatically changed my filenames to filename.text.plain.slim.
When I run my tests, each one related to Mailers fails with an "ActionView::MissingTemplate" error.
I think your template name should be filename.text.slim instead of filename.text.plain.slim.

By using Kristin Gem, Is there any possible way to store the result of the conversion on a variable instead of outputting it as a file?
Assuming that the link below goes to the gem you are talking about, no. The gem is a very thin layer on top of pdf2htmlEX and simply spawns the process with the arguments passed. Further, pdf2htmlEX doesn't seem to support redirecting its output and adding this feature doesn't seem to be on their todo list, so adding this functionality would require wrapping a different converter.
I think your best bet would be to save load the HTML to a variable after creation.

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
A basic task: evaluate field's value and show warning if results are not satisfying. The actual code doesn't matter, since it works perfectly until I actually change sample warning's test to the one, which should actually be there, which throws this accursed error at me:
Error: Encoding::UndefinedConversionError: U+0417 from UTF-8 to ISO-8859-1
In any other case I would've used i18n or magic comment, but neither seem to work here, since apparently you can't mix ruby into .coffee file. Is there any way to avoid this without resorting to putting unnecessary javascript into views?
You can use ruby in coffeescript assets. Just rename the file to .js.erb.coffee and use good old <%= ruby_code %>.
I have installed the less-rails gem as I am keen to use the colour manipulation LESS offers. I need to extract a colour from my database as my themes base colour, and build up from there.
I have the static CSS, and have renamed it styles.css.less to ensure that rails understands the less extension, which it appears to.
The next thing I tried was to also wrap the file as an erb, to hopefully allow ruby string literals to process before being sent to LESS, and eventually outputting as valid CSS (still with me?)
The file is now called style.css.less.erb. While the file simple contains valid CSS, the processing of the document works. As soon as I add a ruby string literal, it fails.
color: #{"#112233"};
In the chrome debugger, nothing after this line is getting processed.
What am I doing wrong, and how should I do what I am trying to do?
As Chowlett says in comments, you should use erb syntax: <%= "#112233" %>
Next step is get that value from db. If this color value is application-wide, probably you are looking for settings in db solution. I use rails-settings-cached gem for that. Your result code will looks like
color: <%= Setting.foo_color %>
If you are using assets on production, don't forget to recompile them after each setting change.
And if it's not a setting but probably something specific to each user then you can't use application-wide css files for that, but you can write inline css in views.
I'm trying to have a git pre-commit hook perform a syntax check on all Ruby code; there is one on GitHub at https://github.com/cypher/git-ruby-syntax-check.
It attempts to check .erb files by erb -x to translate them into Ruby code and then passes the output to ruby -c for syntax checking. Unfortunately, Rails 3 introduced a custom ERB parser that is incompatible with Ruby's standard ERB, and so the pre-commit hook is finding errors where there are none.
Is there some equivalent to erb -x that will output Ruby code from a Rails 3 ERB file?
I have not dug much into either of these but you might try rails-erb-check (Git project) or this blog entry. I agree with shingara but the Blog Post describes a situation where this is useful and I wonder if you are in a similar position:
Diaspora is pretty fluid right now. This means we are have some green
tests, some missing tests, and other tests that check intent (not
implementation). In an ideal world, I suppose test cases would cover
all of our bases...
Until then, I've added a new task to my fork, check_syntax:all. This
breaks down further to the subtasks check_syntax:erb,
check_syntax:haml, check_syntax:haml_ruby, check_syntax:sass, and
check_syntax:yaml.
If you get an "argument list too long error" for rails-erb-check , you can try rails-erb-lint which scans your current views folder.
