Vim noob here. I have code folding working in most places, via indent mode, but for some reason I cannot get Vim to fold .html.erb files in ruby... even with indents.
Here's the relevant region of my vimrc. Is there something else I need to do to make Vim aware of the erb files? Is it possible to customize my folding per file type?
I'm running all the Janus plugins, so have rails.vim, etc. all installed.
let ruby_fold=1
set foldmethod=indent
set foldcolumn=0
set foldlevel=99
nnoremap <space> za<cr>
It's a difficult question, because there's probably something in your vim configuration that inhibits folding and I, for example, can't reproduce it. But I can suggest a few things you could try.
First of all, check what the values of those settings are in the actual buffer. Meaning, open up an erb file and check if the settings are correct. In order to do that, you can type, for example, set foldmethod, which will echo the current value of foldmethod to the screen. If one of the settings doesn't match the ones in your .vimrc, then that might be the problem.
Also, see if the file really does have the "eruby" filetype. If it's not displayed in your statusline, you could check that with set filetype.
Most importantly, one way of customizing settings per filetype is by creating a file with the filetype's name inside the ~/.vim/ftplugin directory. In your case, you can create the file ~/.vim/ftplugin/eruby.vim and put any filetype-specific settings in it. Setting them with setlocal instead of set will keep them local to the file. If it turns out the settings for erb are off, you can "fix" them by putting the values you want there.

Whenever I open up test.log from any rails application I get the following screenshot in Sublime. I've tried messing around with encodings, but couldn't find anything that fixed it.
Any ideas on what is going on?
These are control characters used to add colour to the log files. Sublime text apparently doesn't support this.
If you're mostly going to be viewing log files with editors that don't understand these colour codes you can turn this off with the rails config.colorize_logging setting
There's a Sublime package to turn these ANSI/vt100 escape sequences into colored text -- SublimeANSI
(use Package Control and look for ANSIescape) -- this adds an "ANSI" file type that will display your log file in glorious color. (The file is displayed read-only but you can change the type back to "Plain Text" if you want to edit it.)
Backing up Tom Hundt's answer... SublimeANSI is the way to go. Compare these before/after shots:
Sublime's default rendering of colorized Rails log output:
Now change the syntax highlighting to ANSI:
Now, marvel in the majesty of SumblimeANSI's rendering:

Note: To install it in Package Manager, search for "ANSIescape" ... NOT "SublimeANSI". This confused me for a hot minute.
I am trying to set some tab indent configurations in Vim. Unfortunately I can't get it working.
In my last line I use
u FileType javascript set tabstop=4
in the hope of having the tab width set to 4.
But when I open a .js file and press tab it inserts only 2 spaces. I tried to comment out the other whitespace stuff without success.
Here is also my full vimrc: https://gist.github.com/919909
How do I set the tabs and so on for Javascript files, and why does the above not work?
Update
The problem seems to be somewhere else as when editing new Javascript files it works as expected. It only seems to behave differently on the Javascript files in my Rails project.
How could that be? I have a Rails.vim plugin installed, could that be the cause?
'tabstop' is the number of spaces a tab character in the file counts for. The number of spaces of an indentation level is set with the 'shitfwidth' option, and the number of spaces that a tab counts for when doing edit operations is set with 'softtabstop'. It's a little complicated, but if you set both 'shitfwidth' and 'softtabstop' to the same value, you'll probably get what you want. You can keep 'tabstop' at the default value.
If you are one of those that like spaces all the time and not tabs, you these settings will probably suit you.
The Rails plugin is probably setting some of these leading to the different behavior you're experiencing.
Ok, the root of the problem seems to be in Rails.vim (see https://github.com/tpope/vim-rails/pull/78)
But there is also this easy solution:
autocmd User Rails/**/*.js set tabstop=4
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)
I am using the lightweight SciTE Text editor and I like it very much.
I would like to configure it in order to see the line numbers displayed when I open it.
I don't want to check the "View\Line Number" menu every time.
I think that I can do it but I don't see the entry in my global options file. Does anybody know how to do it?
Try this in SciTEGlobal.properties:
# Sizes and visibility in edit pane
line.margin.visible=1
line.margin.width=5
# Sizes and visibility in edit pane
line.margin.visible=1
line.margin.width=2+ # + will expand if needed
Having seen the other answers i would say it is more "clean" to save to User options file, because it is a user setting and you might also transfer this setting together with your home directory f.e. when you migrate or copy it for other reason. Also in this cases your scite would still behave like YOU (and possibly other users) expect.
add this line to User options file ".SciTEUser.properties":
line.margin.visible=1
line.margin.width=0+ # + will expand if needed
additional comment:
for my taste the font of scite in linux is too small and therefore i also added these lines to .SciTEUser.properties:
magnification=1
output.magnification=1
I want to use a latex editor that has auto completion feature for existing references in a latex file. Do you know any good ones? I am trying to find this feature in texniccenter, but I guess it doesn't exist or I could't find it yet.
Update:
Ok, I found how to enable auto completion in Texniccenter. I needed first create a project. Then open the file in this project (or copy its text). Now Ctrl-Space inside a \ref{} tag completes the reference automatically.
Texlipse does this, also with Ctrl+Space.
Inlage includes such a function, too. New commands and new environments will also appear in the auto completion list. If you use extern BibTex files the \cite{} command will open a list with your articles and books from you .bib file.
Ok, I found it. I needed first create a project. Then open the file in this project (or copy its text). Now Ctrl-Space inside a \ref{} tag completes the reference automatically.
Kile has reference completion. If you type Ctrl+Space inside of a \ref{}, you get a list of all the references (that existed last time you compiled, of course).
LEd presents a click list of them when in a \ref{}
The RefTeX mode for Emacs will do what you're asking for: the shortcut C-c ) activates the "insert a \ref" mode (of course, you can customize which type of reference: fancyref, hyperref, etc) and pressing TAB will allow you to start typing and autocomplete by tabbing again after typing some characters.
It also figures out (or asks if it can't) what sort of ref you're inserting and shows a list of all the defined \labels in your document, selectable with the arrow keys or C-n / C-p.
Now we just need a Vi user to come along and tell us how to do it there...
Now texmaker does, not need any special key.
