Screen capture of my Intellij IDEA shows problem. My own keywords are ok, but Robot Framework keywords are all underlined with red color. Not good.
I'm using Intellij IDEA to develop Robot Framework test cases using Selenium Library. My IDEA is recognizing all Keyword that I have implemented, but doesn't recognize any library Keywords. It is underlining those with red color and doesn't suggest or give any hints for those. Here is version information about my IDEA:
IntelliJ IDEA 2017.1.5
Do you have any suggestions? What should I check from my IDEA?
I know that this is an old question, but I stumbled upon this during my research for the same problem, so here is my result.
In the description of the Robot Framework Plugin for IntelliJ IDEA and PyCharm is stated that the support for library keywords is only with the help of either PyCharm or the Python plugin for IntelliJ IDEA. But unfortunately, that is only available for IntelliJ IDEA Ultimate Edition. There is a version for the Community edition, but it's not exactly the same.
Make sure you imported Selenium Library under Settings. It doesn't come automatically like the BuiltIn keywords.
Also, make sure you are importing the right version of Selenium. There's SeleniumLibrary, Selenium2Library, and Selenium2LibraryExtended.
The only reason I'm suggesting this is because you didn't share your Settings code, which would give me a better picture of what you're asking.
I am using Lua (I am newbie on it) for scripting under Sublime Text 2 and Linux and I would like to debug my script so I would like to set some breakpoints. How can I achieve this?
Sublime text 2 is just a text editor, it is not an environment and so you cannot debug in it. I don't actually script Lua, so I am not that familiar with the tools available for it but they are out there.
Corona Labs released plugin for Sublime, which supports debugging. Check out: https://sublime.wbond.net/packages/Corona%20Editor
As far as I see - no such a thing thing for Sublime Text. Only some kind of Corona Texmate Bundle[1] derivative for Sublime[2].
Also there are couple of links for Corona SDK IDEs in official Corona page[3]. Some of them provides debugging functionality...

It should be possible to write a plugin for SLT2/3
Plugins are written in Python, so there is no compilation needed or anything like that. But it's still a huge effort due to the fact that there is virtually no documentation available for the SLT scripting API.
Your best bet would be to borrow from existing projects like
https://github.com/Kindari/SublimeXdebug
http://sokolovstas.github.io/SublimeWebInspector/
There is also Outlaw which claims to be an IDE but it does not seem to support debugging and is more like a project manager with a mediocre editor attached. You can probably do the same in SLT with a few commandlets. It does seem to have completion though.
What is the recommended development process for D programs that use packages that are cloned from github and separately built?
Typically in relation to how C/C++ projects are built using make, autotools, cmake, etc.
Most other build specifications have an install target. Should there be an install target in the build or should we just link a library directly from where it is placed when built and add register its includes in D_INCLUDE_PATH and then direct to them using DFLAGS=-I<D_INCLUDE_PATH>?
I realise my comment can actually be an answer to the question, so here it is:
D development process can't be different than similar in C or C++ world. Is that really difficult to see? Almost all C and C++ compilers generate "native" code. D is not an exception. There was the D.NET project that could target .NET, but it is inactive for years...
Furthermore, all tools used in C/C++ based projects can be easily used for anything else. CMake can be used in Java or .NET projects as well. Same goes for Make and/or Autotools. Why are Maven and Ant more popular in Java world is a different story.
Speaking about them, you can use Maven or Ant in the D development process! Hands down, you need to write your own Maven plugins to make it more easy and flexible, but it is doable, and would in fact be a very nice project.
From what I have seen, D programmers stick to the good, old Make, or write BASH script to do the whole thing. However, I've seen people from the Lycus foundation use WAF. If you are Python programmer, you will just LOVE WAF. If not, try similar things - I've seen people use SCons, Remake, Premake, etc...
DSSS+Rebuild is the closest thing to a very useful such tool made with D. Unfortunately they are dead projects. :(
I am working on a maven-style tool, but considering the amount of time I have - it will be usable in 2014. :)
I would go with scons, which has support for D, thanks to Russel Winder:

If not, then POM (plain old make).

This is the same question for older version of Scala, but they say that Eclipse plugin has been improved vastly. Is it the best IDE now? How do different Scala IDE compare today?
I've been pretty successful with IDEA 9. I've briefly tried both Netbeans and Eclipse and wasn't able to get what I wanted. Eclipse's code-complete didn't behave as well as I'd have liked, and I couldn't find a way to make Netbeans handle Scala scripts; It'd just complain that the file wasn't a class.
To be clear, I've been using IDEA for a few years for Java, so keep that in mind:)
For the moment, Scala Plugin in IntelliJ IDEA is the best. It handles Scala 2.8 well. IntelliJ IDEA Community Edition is now free and open source (and works with Scala), so I can't see any reason for not using it.
The plugin is still somewhat buggy (many "false negatives", i.e. the code without red underscores may not compile successfully; but almost no "false positives"), but perfectly usable. The best thing is that you can use IDEA's excellent debugger with Scala (not without some issues, but it actually works!).
FSC (Fast Scala Compiler) is also supported in latest builds. A huge time-saver.
The plugin development team is quite responsive. Some of the guys work directly in JetBrains and possess intimate knowledge about IDEA platform, so the development progresses fast.
JetBrains IDEA's Scala plug-in handles 2.7 and 2.8 equally well.
I cannot make any comparisons because I have used only IDEA.
Using Eclipse Helios with the dev-version of the new Scala(2.8) plugin, as there isn't an official release yet. That is beta, definitively -- but I can't confirm the frequently expressed opinion that this plugin is outright horrible ;-)
I'd say, the experience is already OK-ish, and indeed better than the current state of affairs with the Groovy plugin. OTOH, the experience with plain Java is way more smooth (feels like flying at times), and the current CDT I'd rate somewhat in between.
Incremental compile and error highlighting work quite well for me; tweaking a DSL implementation into form just by continuously rewriting your code until the error markers are gone -- without ever having to test-run your program -- is outright fun and just again shows that FP / static typing rocks!
Problems encountered from time to time:
- implicits and nested types in other compilation units (esp. nested / super packages) aren't picked up at times when there are still other errors around; they will be picked up after an full build
- there seems to be a memory leak in the version I'm using right now (from end august 2010), necessitating to restart the workbench after some hours of work
- beware when you're using AspectJ, to make sure you get a version of the Scala plugin which relies on a JDT weaving bundle version which also works with AJDT
PS: I'm using maven builds in all my projects and generated the eclipse projects with the eclipse-maven-plugin, and then imported them as plain-flat eclipse projects. I can just strongly recommend everyone to keep away from the M2-eclipse plugin (for maven) in its current (2010) state, it makes your workbench painfully slow, is buggy and has lots of almost unpredictable behaviour, because it constantly tries to do magic things behind the scenes (and besides that, the aspectj support is broken since this spring)
i use both eclipse and IDEA
eclipse supports type detection is
better than IDEA (it is very
neccessery thing if you want program
in functional style that you can be
aware from type of expressions and
variables.)
Edit1: IDEA supports type detection like eclipse but you have
to define a value in your functions
for example: def
testTs[A](a:List[String],b:List[A])
= for{
ai <- a
bi <- b
} yield (ai,bi) } should be converted to def
testTs[A](a:List[String],b:List[A]):List[(String,A)]={
val result = for{
ai <- a
bi <- b
} yield (ai,bi) } also instead of hover your mouse over variables you must press ctrl+q when your mouse is hover on that variable
eclipse have some problems in code
completion (when you use a variable
in next line and you want get a
property of this variable eclipse
show wrong code suggestions)
in IDEA ruining a scala application
is 5 sec slower than eclipse (there is some solution for bust IDEA run time but these have side effect have some problems)
in idea there is a well known problem with double click speed that show itself in many cases like opening a file or selecting an string in source... you can increase double click time out by creating (or editing) /home/.Xresources and add this line: *.multiClickTime: 400
Edit1: in summery i prefer to use IDEA rather than eclipse
My experiences clearly point to IntelliJ IDEA:
About six months ago, when I started a serious Scala (multi module) project, I had to abandon Eclipse as my favorite Java IDE and switched to IntelliJ (9.0.x). Eclipse Scala IDE was way to buggy and often stopped responding at some point, even for the most simple projects. For CI (Hudson) and command line build, I depend on Maven (with Scala plugin). The Maven dependencies (incl. Scala libs) are picked up nicely by IntelliJ.
A few days back I updated to IDEA X (CE) with the current plugin (nightly build) and work became even smoother. Although fsc still terminates after a while when inactive.
From what I see, I'd like to add, that there seems to be way more activity on the IntelliJ side to respond to bugs and improve the plugin continuously. Correct me when I'm wrong, but Eclipse Scala IDE development seems almost stalled. Still no 'official' Helios release!
NB: Just to provide some context (not bragging, really): The aforementioned project consists of about 25 Scala modules (POMs), 5 Java modules, 325 Scala files with a total of about 360 Scala classes, case classes and traits (> 19 kLOC, including comments). My platform is OS X 10.6, Scala 2.8.1, Java 1.6.
UPDATE: After having the need for pretty extensive refactorings (mainly move class, rename package), I discovered that the recent IDEA 10.0.1 plugin 0.4.413 (and probably older versions, too) has quite some problems getting stuff right. I don't want to explain the specifics, but I (almost ever) ended up manually fixing unresolved references or otherwise messed-up code. You can have a look at http://youtrack.jetbrains.net to get an idea.
For everyone who is really considering doing some serious development with Scala, I strongly recommend to evaluate the IDEs in question beyond the basics. When you are into an agile approach, which in my option requires a painless refactoring support without surprises (especially in multi-module projects), things are pretty tight at the moment.
It would be pretty neat, if someone came up with a IDE independent specification-like list of refactorings (and desired outcomes), which could be used to verify an IDE's refactoring support.
A non-answer: None.
Based on what a perceived majority says, IDEA is probably the best Scala IDE today. And it (read: the Scala plugin) sucks. It does not handle fsc well, type inference is a mess, many errors are not shown, a number of non-errors are marked as errors, it is slow (when inspections are turned on), the test runner silently swallows aborting (!= failing) tests, ...
So I switched to a simple text editor with syntax highlighting on one and a maximized shell with SBT (simple build tool) on the other screen. Awesome! SBT is responsive (you can let file changes trigger recompilation of affected code and even reruns of tests), manages dependencies very smoothly and has helpful output (esp for tests; using ScalaTest). SBT increased my productivity compared to IDEA a lot.
You lose code completion, of course, altough geany offers me identified symbols. But as long as IDEs don't get type inference to work properly code completion does not help, anyway.
Some people care a lot about code refactoring. Well, the IDEs apparently don't make a good job there either. Even if they would, I'd rather only open them for this particular task than use them all the time.
I think that the best option so far is the ScalaIDE for Eclipse. You can go to the ScalaIDE Web Site and look around to see by yourself.
http://scala-ide.org/
Strong points I see about it are:
documentation,
tutorials,
constant releases,
support from Typesafe.
Here below a summary of the main features:
Scala IDE provides support for development of Scala applications in the Eclipse platform. Its main target is the support for the Scala language and the integration with the Eclipse Java tools. It provides many of the features Eclipse users have come to expect including:
Support for mixed Scala/Java projects and any combination of Scala/Java project dependencies. Type driven operations are transparent across Scala and Java files and projects, allowing straightforward references from Scala to Java and vice versa.
A Scala editor with syntax highlighting, inferred type, hyperlinking to definitions, code completion, error and warning markers, indentation, brace matching.
Project and source navigation including Scala support in the Package explorer view with embedded outline, outline view, quick outline, open type, open type hierarchy.
Incremental compilation, application launching with integrated debugger, hyperlinking from stack traces to Scala source, interactive console.
Support for Eclipse plug-in and OSGi development including hyperlinking to Scala source from plugin.xml and manifest files.
UPDATE: the features and advantages are mentioned on this answer are for version 2.9 and 2.10 of Scala, because it has been already discontinued. see here:
"The 2.0.1 release is only available for Scala 2.9, if you would like to use the Scala IDE with Scala 2.8, please install the 2.0.0 release (support for Scala 2.8 has been discontinued after the 2.0.0 version)"
The officially endorsed and supported (by Typesafe) for Scala 2.9 is Eclipse. The current version is far superior to prior versions and includes a context-aware REPL, full-featured debugger, and even the ability to debug REPL statements. I think this question needs to be updated and the answers revisited.
I don't recommend the Scala IDE/Eclipse. It doesn't have a lot of the features that are even available for Eclipse with Java. And there are bugs.
I am using the latest NetBeans and haven't tried anything else. I've met at least 2 notable bugs in NetBeans while coding in Scala:
One: NB occasionally come unable to run a program, hanging on classpath scanning.
Solution: Create a new project, copy your code there and go on.
Comment: This bug is more than 10 years old.
Two: Sometimes NB can't see members of particular namespaces or classes and complains when you use them.
Solution: Just ignore and go on - compiler founds no errors and the program works.
I'd recommend IDEA's plugin for now.
The Scala plugin for NetBeans is quite nice too. It doesn't yet support NetBeans 6.9, the newest release, though, and you still need to download it manually instead of installing it directly from the plugin manager inside NetBeans.
However, it integrates better with Maven projects than IDEA's plugin does (this is true for NB and IDEA in general, in my opinion).
It partly depends on your style of working, as all the options have strengths and weaknesses.
If you need refactoring across mixed java/scala projects, then IntelliJ is your only option.
If you want to do any work on the compiler or a compiler plugin, then Eclipse has the advantage of being able to launch a runtime workspace with a custom compiler build, including breakpoints. It also improved massively for the 2.8 Scala release.
Netbeans is a fine choice to go with if you're already very familiar with that platform, the costs of learning a new environment may well outweigh any benefits, and all three solutions are improving rapidly.
I haven't tried netbeans scala plugin yet, but I find that Intellij IDEA plugin is at any way much better a scala ide than the Scala eclipse plugin, which is sooooo slow that drives me crazy.
Though swing applications don't work well with my tiling window manager.
try IDEAX the latest community edition of Intellij IDEA (version 10), it has improved scala plugin which has faster code compilation and exceution in addition to that it has
Maven3 and SBT support with which we can develop Lift applications.
IntelliJ IDEA community edition + Scala Plugin + SBT plugin
For recent versions (2021) the question which ide takes a big portion of the home page https://scala-lang.org/
I searching for and IDE that gives me a (mostly) uniform experience on Linux/Windows and C/C++ and Java. I'm somewhat comfortable with using Netbeans on Windows and I'd like to know what to expect of it on C. I heard the Visual Studio debugger is quite good on C, does this extend to Mono? Is it really more powerful than the one on Netbeans?
I've been using NetBeans for C++ development on Linux for the last month or two and love it. I'm working on an large code base 1+million lines of code. As long as your project references appropriately, I've found that NetBeans will provide "intellisense" information with hardly any issues. Now, it's not perfect, and is definitely not as good as Java, but I've not found a better alternative. NetBeans debugger, which is a front-end to gdb, works well also. Much easier, and in my experience more stable than DDD. I've not tried Mono projects using NetBeans so I can't speak to that.
This link explains how to setup a C++ project in NetBeans and may shed more light on the subject for you. This is for NetBeans 6.7 NetBeans C/C++.
Eclipse CDT is quite usable as well
you can use codeblocks it is also a well and exceptionally good for c/c++.
I don't think so, since it consumes extreme amounts of memory and can hog your CPU completely if you have a lot of projects open. It actually uses every bit of CPU it can if it feels for it, and it does so for a long time, rendering the whole application useless. This is of course completely unacceptable for a modern UI application. It also feels kind of sluggish.
Because of this I switched to Visual Studio Code for Linux. It's not a full blown IDE but I don't need that anyways. I'm not in the "flow" of it yet, but I think it has potential.
The problem of VS C++ is don't have intellisense. Netbeans C++ is a good product. But i suggest DevC++ editor, its free and come with lot of pluggins and intellisense.
