From what I know, CodeSniffer follows a certain set of coding standards and checks your code if it follows the said standards. But sublimelinter-php does this too. Are they different or are they just the same? Because I installed both plugins on my Sublime Text 3.
SublimeLinter-phpcs allows you to run PHP_CodeSniffer over your code, ensuring it conforms to whatever coding standard you use.
SublimeLinter-php allows you tun run php -l over your code, ensuring that it does not contain any syntax errors. It does not seem to check any coding standards.
PHP_CodeSniffer does not actually check code for syntax errors, so having both installed is probably a good idea. Use SublimeLinter-php to make sure your code is going to run, and SublimeLinter-phpcs to make sure your coding standards are being followed.

I am new to Sublime and to Ruby. I have been developing Java for 10+ years, and what I miss, is: autocomplete, in the meaning of:
using: Sublime3 (ok if had to switch to 2 to get this option) + Rails.
issue: I want: I type: "MyClass. [DOT]" say: I type the dot
and then: a list of methods of this class are displayed. These methods that are defined by default (as of heritage), and those that I have defined, in the class definition.
I am aware of the 'duck-typing' style, such: also these methods, that this object itself is able to use, would be a plus.
While, I would be happy with the first two (heritage and self.methods).
Yes I am aware that the Ruby-community is sort of pure coding; I like it also, and I also appreciate an editor that helps.
I have read through answers in GITHUB, and I could not figure out if that is existing or not .. it seems, the Ruby-people do not understand this Java-coding idea.
Thank you for any link or answer.
Sublime is a text editor, is not an IDE. In the Java world you are likely used to write your code with IDE (such as Netbeans, Eclipse, Intellij IDEA), I have never seen Java developers using a pure text editor.
There are some IDE for Ruby. However, the highly dynamic and loosely typed nature of Ruby makes it really hard to provide an accurate IntelliSense code completion. Both the assumption that the Ruby community pretends to be pure, or Ruby-people do not understand Java-coding idea are simply wrong. Several Ruby developers approached the language from Java, therefore they are perfectly aware of how the Java world works.
If you feel more comfortable with an IDE, try to search for a Ruby one. RubyMine is a great product, and if you come from Java world you may already be familiar with Intellij IDEA. There are also plugins for Netbeans and Eclipse, but the runtime evaluation capabilities of RubyMine are far superior and it's also the most up-to-date.
Most of text editors, such as TextMate, Sublime Text, Atom, etc understands Ruby and provide Ruby syntax highlighting and additional features, some of them even autocompletion, but IDE-level features as you would expect from the Java world.
Autocomplete is possible in Sublime - there are several packages for Python, including the excellent Anaconda plugin. Coverage for Ruby isn't quite as deep, but I did find SublimeRsense which may fit your needs. The README implies that it's for Atom, but I think that's just left over from another repo. I'm not a Rubyist, so I didn't install it, but the directions looked pretty straightforward.
That being said, depending on your personal preferences and knowledge, an IDE may work better for you. Of course, it'll take up a lot more room on your HD and in memory, and may get in your way at times, but with that comes many more features that you won't find in a text editor, even one as advanced as Sublime. Try them both out, and use what works for you. Personally, I prefer Sublime over IDEs, as I find many of their "features" annoying, but you'll have to see what best matches your style and needs.
I want to step into extension development for Gnome Shell, but I can't seem to understand how I do a few tasks in Looking Glass lg to actually debug my stuff.
When I type global.log("hi"); into LG, it throws me back r(...) = undefined. Why?
When I want to debug an extensions that doesn't load, how do I do that?
It would be nice to see why an extension can't be loaded.
I tried Main.ExtensionSystem.loadExtension() but it returns undefined no matter if I give it the extension's name string or the extension's object.
Where do I find documentation for classes, objects and member methods?
(The LG inspector does not seem to be able to inspect functions.)
If I had these resources I could at least start to work on updating some extensions for newer Gnome versions. I would not ask these simple questions if they would be nicely explained somewhere but getting all the info seems really tough (I've googled for hours).
1: LookingGlass is basically a GJS console. It allows you to execute and test lines of GJS, grab and manipulate objects and use r(...) to use results in following commands.
The reason you get r(...) = undefined is because log(String); does not return anything, thus the result is undefined.
2: Either log throughout init() and enable(), then check where it breaks and try to pinpoint the breaking line using log or commenting out lines of code (although the culprit is probably defined in the general logging, described in the section at the bottom).
3: There is no official documentation. They have some outdated tutorials for GNOME Shell 3.4 with a small difference explanation to 3.6, a few pages on the C(++) ends of the libraries you use (most of the functions, variables and constants use the same names though), but for any real info you'd need experience, digging through other GNOME and shell extension code or some unofficial sources. Unofficial sources aren't always up to date, however.
Up to date generated docs at RooJS, although at least events are off as they are separated with - (minus) rather than _ (underscore).
Old, but mostly useful documentation, MathematicalCoffee has more useful things, like in depth explained code that is quite a solid learning source.
Generated docs, almost everything is there, very extensive, but sometimes the site drops offline for a few days. You could try to clone the git repo to run it locally, but the readme.md is a verbatim copy of what they forked...
More recent reference made by a user, although this is quite extensive, it's not of much use if you're on an older version of GNOME Shell, as deprecated and old is more likely to work than next gen stuff.
I recommend checking the official extensions website and go through whatever interesting extensions' source code you can get, as that is your best bet to learn anything.
Generally Debugging gnome can be done in several ways.
- use the log() function and follow journalctl in a commandline, check either GNOME or JS, use journalctl -f | grep -i js (or use grep -i gnome). You will see some warnings no matter what, but most mention what extension they're from. This is nice and works on all distros implementing systemd
- Or log a specific process that is a part of GNOME like journalctl /usr/bin/gnome-session -f -o cat, just beware that some distros and versions log to different files and old GNOME versions often log to whatever your display manager logs to.
- use the official (albeit tricky) manner of logging: GNOME on debugging.
I personally couldn't get this to work.
How do you use Xcode's Extract refactoring tool?
Whatever code I select, I always get the same unhelpful error message.
The selection does not contain anything that can be extracted. Make a
different selection and try again.
See the screenshots below:
What do I need to follow to have it work?
I am doing this on a simple iOS project, nothing special, no C++. Tried with the latest version of Xcode (4.4) and the newer latest developer preview releases.
Is this a bug? Any workaround?
For some strange reason if you have a block that doesn't create an obvious return value of pick up parameters XCode complains if you include the newlines. In my opinion this is a bug, as whitespace should be ignore. Just make sure you don't include the newlines. For example, the following works with "Refactor > Extract Method":
Automated refactoring tools first check that certain preconditions are true before applying the requested refactoring. In this case, it seems that the preconditions failed. I've done plenty of similar Extract Method refactorings in XCode and I can't why there's a problem with the code you selected. Perhaps there's some subtle dependency that isn't apparent in the code you show.
I'm not sure if I'd call this a bug. In developing a refactoring tool the developer can always make the preconditions a bit weaker at the price of more complicated refactoring logic.
Doesn't solve your problem but perhaps is of some help.
How to generate tags file for Go source
In mac, I installed exuberant ctags , and tried the below command in source directory
ctags -f gosource.tags -R `pwd`
But, it doesn't consider *.go files. Do I have to use -h option? But, isn't it only for header files, as per the manual?
Please give me the correct command so that I can use the tags file with vim. I also prefer absolute path so that I can keep the file anywhere
Thanks.
Edit:
I assumed current ctags support Go, seeing http://groups.google.com/group/golang-nuts/browse_thread/thread/3a4848db231b02c9.
but, http://ctags.sourceforge.net/languages.html desn't have go listed.
Add the following to ~/.ctags
--langdef=Go
--langmap=Go:.go
--regex-Go=/func([ \t]+\([^)]+\))?[ \t]+([a-zA-Z0-9_]+)/\2/d,func/
--regex-Go=/var[ \t]+([a-zA-Z_][a-zA-Z0-9_]+)/\1/d,var/
--regex-Go=/type[ \t]+([a-zA-Z_][a-zA-Z0-9_]+)/\1/d,type/
(From http://go-wise.blogspot.com/2011/09/using-ctags-with-go.html)
--langdef=Go
--langmap=Go:.go
--regex-Go=/func([ \t]+\([^)]+\))?[ \t]+([a-zA-Z0-9_]+)/\2/f,func/
--regex-Go=/var[ \t]+([a-zA-Z_][a-zA-Z0-9_]+)/\1/v,var/
--regex-Go=/type[ \t]+([a-zA-Z_][a-zA-Z0-9_]+)/\1/t,type/
Does indeed work with ctags 5.8. One slight change from the previous poster, ctags requires unique 1-char types at the ends of the regex lines. Thus /d,func/ should read /f,func/ intuitively. This allows the ctags to distinguish between and identify types, allowing ctags --go-types=fvt i.e.
I saw your post, bumbled around a bit trying to find a good tool for the job, tried ctags, and ultimately was unsatisfied. I wrote a program 'gotags' in Go that generates a ctags file for Go code. Its better than the current ctags support because, for example, it tags struct field names as well as the struct name itself. You can get it here: https://github.com/necro351/gotags.
Its a nice short simple Go program because it uses the standard library parser and has no extra features other than good Go parsing and tagging. Just check it out (or go get it) and do a go install. Also, if you have any suggestions or ideas about improving it, let me know.
Edit: I am an active Gopher and so will be updating this tool over time and as I use it.
Edit: I am not actively developing Go anymore. But my tool is very short and pretty much works as is so it should "just work" :)
universal-ctags supports Go. It's the successor of exuberant-ctags and works perfectly fine. See here for the man pages.
Check Go Dashborad/Projects, section "Tag Generators". Status of those tools is not known to me.
Edit 2011-11-22: Latest egotags fork announced today (cyclic reference possible ;-)
Does Ruby have any tools along the lines of pylint for analyzing source code for errors and simple coding standards?
It would be nice if it could be integrated with cruisecontrolrb for continuous integration.
Or does everyone write such good tests that they don't need source code checkers!
I reviewed a bunch of Ruby tools that are available here
http://devver.wordpress.com/2008/10/03/ruby-tools-roundup/
most of the tools were mentioned by webmat, but if you want more information I go pretty in depth with examples.
I also highly recommend using Metric-Fu it gives you a on gem/plugin install of 3 of the more popular tools and is built with cruisecontrolrb integration in mind.
The creator has a great post that should help get you up and running in no time.

There has been a lot of activity in Ruby tools lately which I think is a good sign of a growing and maturing language.
Check these out:
on Ruby Inside, an article presenting Towelie, Flay and Simian, all tools to find code duplication
Towelie
flay
Simian (a more general tool that supports Ruby among other languages)
reek: a code smell detector for Ruby
Roodi: checks the style of your Ruby code
flog: a code complexity analyzer
rcov: will give you a C0 (if I remember correctly) code coverage analysis. But be careful though. 100% coverage is very costly and doesn't mean perfect code.
heckle: changes your code in subtle manners and runs your test suite to see if it catches it. Brutal :-)
Since they're all command-line tools they can all be integrated simply as cc.rb tasks. Just whip out your regex skillz to pick the important part of the output.
I recommend you first try them out by hand to see if they play well with your codebase and if you like the info they give you. Once you find a few that give you value, then spend time integrating them in your cc.
One recently-updated interesting-looking tool is Ruby Object Oriented Design Inferometer - roodi for short. It's at v1.3.0, so I'm guessing it's fairly mature.
I haven't tried it myself, because my code is of course already beyond reproach (hah).
As for test coverage (oh dear, I haven't tried this one either) there's rcov
Also (look, I am definitely going to try some of these today. One at least) you might care to take a look at flog and flay for another style checker and a refactoring candidate finder.
There's also the built-in warnings you can enable with a quick:
ruby -w
Or setting the global variable $VERBOSE to true at any point.
Code metrics on ruby toolbox website.
Rubocop is a widely-used static code analyzer.
I just released Excellent which implements several checks on Ruby code. It combines roodi, reek and flog and also adds some Rails specific checks:
gem sources -a http://gems.github.com
sudo gem install simplabs-excellent
May be helpful...
