Hey i have a little question
Text file:
scripts { "example_1", "example_2" }
I have a text file with table scripts. And in my lua file I want to get all scripts thad is in thad table.
I already know how to get the text file.
But I don't know how how to extracts the scripts
Thanks in Advance
Define a function called scripts that receives a table and then load your text file with dofile.
I'm curious as to how I could get org-mode to automatically render sub/superscripts. Here is the org-mode wiki page on using this. At the moment I can properly get it to work but I need to use "C-c C-x \". Is there some code solution I could put in my init.el file or something to get this to execute when opening any file?
I toggled org-pretty-entities with M-x, org-toggle-pretty-entities and that did the trick. Alternatively you could place #+STARTUP entitiespretty at the beginning of your file.
I'm using:
Rails 3.2x
Spree 1.2
Ruby 1.9.3x
I'm trying to edit the title of one of my pages, and I cannot find where it is getting defined. It is showing up in my base ERB file as 'title', but that name is sufficiently generic to make it next to impossible to find where it is defined.
I have prodded everywhere I can think, I've tried searching for "title =", but nothing is working. I tried calling source_location on it, but that appears to only work on methods.
Any tricks for finding where a variable is defined?
I can't think of an elegant way. A dumb-but-probably-effective way would be to dump stack trace in your erb, then see what those locations are doing and if title is defined there. It has to enter somewhere between the start of program and invoking your erb.
When I can't find something, I use grep -ri some_string . at the command-line to recursively search all the content of the directory.
It's also a good tactic to let your editor search all the source code, since the ones worth using have the ability to search through all files in a directory.
it is created from a mixture of product names, a site config, and something else
An alternate trick is to add a HTML-comment section in your ERB file, and put the pertinent information for the components used to create the title into that section. Then, let the pages be generated and look inside the page's content to determine what table and row ID it is, the site_config filename, etc.
You really should be able to figure it out based on the parts that are concatenated to build the title and then search your database or files. That information isn't magically created out of thin air by Rails; Someone had to tell Rails how to define the title. But, people move on, or they don't document correctly, so try the embedded information trick.
Something that I've had a good hard look for and I have not been able to find, is how to efficiently obtain a hard copy of Javadocs? Obviously, one solution is simply to navigate to each page and execute a browser print, but there's got to be a better way! Do you guys have any ideas?
You can use DocBook Doclet (dbdoclet) to create DocBook XML from your JavaDoc Comments. The DocBook XML can then be transformed to PDF or (Singlepage-)HTML.
You can call the tool from the commandline. Point it to your class files and it will generate the DocBook XML. This works similar to the javadoc command which will generate the JavaDoc HTML. Example:
./dbdoclet -sourcepath ~/my-java-program/src/main/java -subpackages org.example
The result is a DocBook XML file in a dbdoclet subdirectory which can be used to create a PDF or HTML file. This can also be done from the command line; I am using the docbkx-maven-plugin for this.
You can do mass conversions with it, but it would require some time to make it work the way you want.
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)
