I noticed just now that package.skeleton() produces R files in which the function names are escaped with backticks. ?Quotes says that "The preferred quote is the backtick (`)", but I don't understand _why_ this is preferred. ?formula gives some clues but points out that there are no guarantees that formulae using non-syntactic names such as `like this` will be accepted. What

Hopefully the subject line didn''t scare you. That said... I have a simple polymorphic relationship (is that possible?): class Part has_many :attachments, :as => :attachable end class Attachment belongs_to :attachable, :polymorphic => true end Calling Part.find(:first).attachments yields this SQL error: ActiveRecord::StatementInvalid: Mysql::Error: Unknown column

Dear all, I just noticed, that prompt () looses backticks that protect default arguments: f <- function (FUN = `*`) {} cat (prompt (f, NA)$usage) yields: \usage{ f(FUN = *) } %- maybe also 'usage' for other objects documented here. without the backticks, which is of course found by R CMD check as syntax error. While this is easily fixed if the .Rd is further edited manually, I

Hi, For those who might not be aware, rjb is a killer gem for using java classes inside your rails app (or any ruby code). Check it out at: http://rubyforge.org/projects/rjb/ I was able to successfully use it in one of my apps that required some code that is only available in java. And it''s much nicer than having to compile a java app, then shell out using backticks, get back the return

Is there a way to do this with llvm-lit, i.e., use the equivalent of backticks? foo takes a single argument, but doesn't read from stdin. // RUN foo some_arg > %t; FileCheck %s < %t // RUN foo `cat %t` | FileCheck --check-prefix=INVERSE // CHECK: {{^[0-9]+$}} // INVERSE: some_arg thanks... don -------------- next part -------------- An HTML attachment was scrubbed...

Hello My email has been broken for a week and some of it seems to have gone astray - so if there are other unanswered wxruby queries kicking about, please repost or forward me them. I have encountered this problem with a DOS box popping up under rubyw / rubyscript2exe; I don''t think it''s related to wxruby. I found them popping up when shelling out with backticks - I believe

Could someone please recommend a reasonably priced IP phone that works well with *, has a decent (full duplex, echo canceling) speakerphone, has at least two line appearances, and can transfer / conference reliably? The Wiki lists 35 brands of hardphone, but: 1. Most seem to be toys. 2. For many, there is no info on e.g. speakerphone characteristics. 3. When one seems technically promising, e.g.

Just a poll here i am looking for a good IDE for rails and wondering what you guys use? features i like in an ide code highlites auto code complete file browser Currently i am using dreamwever but the code highliting is really bad its also a pain to set up other doucment types such as .yml data config. -- Posted via http://www.ruby-forum.com/.

I just noticed the following in update.formula and I'm wondering if this behavior is the intention of the developers. Here's an example: update(`a: b` ~ x, ~ . + y) Note now that the response has no backticks and is interpreted as a:b (i.e. ":" is now an operator). This is because in update.formula the call to terms.formula uses simplify = TRUE. I'm working with data that

Hello. I need to run a single fixture on my server as part of an update to my application. I noticed that the other tables lost their data when I run "rake db:fixtures:load". How do I make it so that only a single fixture runs and ignores the rest?

I'm using Michel Fortin's MDTest cases to rewrite my html2text.php script. Just now I stumbled upon this bug (in PHP Markdown at least): # Input: Backtick: ``\``` # Output: <p>Backtick: ``&#96;``</p> # Should-Be Output: <p>Backtick: <code>`</code></p> If you (Michel) are already aware of this, just ignore me ;-) -- Milian Wolff

Consider: x <- list(`a b` = 1) x$a<tab> (i.e., press the 'tab' key after typing 'x$a') The auto-complete mechanism will fill the buffer like so: x$a b This is not particularly helpful because this is now a syntax error. It seems to me there's a simple fix -- in utils:::specialCompletions(), we can wrap the result of utils:::specialOpCompletionsHelper() with

Radrails! Certainly complies with what you are looking for and much more. (Ctrl-Shift-V to toggle the editor between Model and View, for example). Runs as a standalone application, or as a feature (plugin) on the Eclipse platform. Cross platform either way. Then there''s the cost: it''s free!

I am doing unit-tests for Maruku and every once in a while I run into some doubts. I am posting a lot to the list, but all of these messages should be in-topic (tell me if not). Consider the input: --- `There is a literal backtick (\`) here.` `There is a literal backtick (\\`) here.` ``There is a literal backtick (`) here.`` --- The documentation says that line 2 and 3 are equivalent.

Hi, I'm trying to backup from one machine to the other (automatically via cron) using rsync and ssh password-less public key authentication. I having been trying to set this up following an article in a Linux magazine[1] by only allowing the specific rsync command to run on the remote box. I am using the following rsync command: $ rsync -avz -e "ssh -i ~/.ssh/backup-key" /backup

The upgrade to Rails 1.1 hurt my ability to run tests because it generated the following MySQL error: Mysql::Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''key ON config (key)'' at line 1: CREATE UNIQUE INDEX key ON config (key) I have a table called `config` with a column

I know my subject line seems odd, but I want to replace an expression—such as a variable—with its value. For example, I want to paste() some strings together, assign the result to a variable s, then use the value of s as a variable to hold another value. Something like this: import_subjects <- function (start, iterations) { for (i in 1:iterations) { # iterate from start to end s <-

I''m at a loss as what to look for... I can issue a command result = `some_os_command_string` on my dev system just fine in both a pur ruby test file, and from Rails in dev mode. When I push that code to my server, the backtick command doesn''t work. No failure message -- even if I wrap it in begin/rescue so I have no specific clues to work from. I can run that same back ticked
