If I invoke the lldb help on a given topic, most of it flies off the screen. Example:
(lldb) help expression
I can quit the debugger, and collect the help in typescript, but that's clumsy. Does lldb have a pager, and if so, how is it used?
There isn't currently a pager for the help command. Feel free to file a bug on http://bugs.llvm.org requesting this.

Can someone please help ? I am getting this program not found error with C language. I have been googling for the past 2 weeks and came across bazillions of questions and solutions for this error including on this platform itself but nothing seems to work for me.
Just started with learning programming and really frustrated with not being able to proceed.
I am literally on the verge of giving up and sticking with codeblocks.
Just please, someone sincerely help me if possible.
First of all, the question is not clear. If you can include the files in the folder and your tasks.json that would be ideal.
But from the error, one thing can be assumed is that your launch json is not able to find the hello.exe program. You either first need to generate it using C compiler or use the "preLaunchTask" in launch json, which points to one of the defined tasks in tasks.json.
P.S. You need to first go through the basics of debugging in VS-Code, then hopefully you will not run through problems like this.
I am trying to work with Proteus library but i am not getting how to implement the functionalities of the library.
Can somebody please explain or share some java code to get me understand it better.
The best way to play around with Proteus is to clone the open source repo and run the demo. You will find instructions in the readme.
If there is something else in particular you should ask it as a question on SO.
May be stupid question. I created HSPIPluginB1 project from template, it compiles, runs and connects to HS.
But I've got no idea what to do next? How do I create devices, triggers, etc?
Great question. HSPIPluginB is described here. There's some help in the forum thread linked therein, but, for the most part, that HSPI template doesn't do much more to help. Your best bet, for now, is to hunt through the HS developer forum and documentation (https://homeseer.com/developer-support/). Honestly, it's pretty difficult to write a HomeSeer plugin as is, but that's not the fault of the HSPI project.
Fortunately, I'm working on HSPIPluginC. It's significantly easier to understand, but it's not finished. You can get a glimpse of where I'm going with it by checking out https://github.com/alexdresko/HSPI/issues/77#issuecomment-322885054. If anything, there's probably some useful code in there to help you move forward.
If you have any ideas for how HSPI can be made better, please Create an issue or start up a conversation in the chat room
I have been looking through previous questions regarding this topic and so far none of them answer my question. I am looking for a way (without libraries) to build my own TUI from the ground up. I want to start off with a simple program that reads a directory and displays the contents with the ability to use arrow keys to move up and down highlighting one item. As simple as this may seem this would be all the help I need to get started on the rest of my project.
All I need is for someone to point me in the right direction for clearing and printing to the screen and not using a print statement or external library. Any help would be greatly appreciated.
Well, to be honest, you can. But as others will tell you, curses is the right tool for the job.
That said, this isn't the 80s anymore. <overgeneralization>Everybody uses Xterm.</overgeneralization> Xterm uses ANSI VT100 control codes, mimicking the classic DEC VT-100. If you target this, you should be reasonably ok and portable.
But curses is really nice. It does a lot of the hard work for you (and there's plenty of hard work left to keep you busy).
Umm, I've been using Eclipse for Java development and I am trying to use it now for making C apps.
The problem is that I don't feel too comfortable with it. Namely:
I need to include headers by hand, i.e. not automatically.
I've never seen a 'quickfix' to be available for any problem.
I can't spot the problem before it has been compiled.
Any ideas on how I could make myself feel a bit better?
Sorry if my questions are rather stupid, but getting the way down from Java to C is rather hard on me.
Thanks!
Yeah its a little harder to go from Java to C, Java didn't exist when I was programming C.
Some comments:
Automatically including headers is difficult in C
See #include headers in C/C++
You could use lint to catch some errors...

Consider doing TDD using something like gTest, and automate your build process.
http://www.slideshare.net/amritayan/test-driven-development-in-c, might help you develop a different rhythm.

Have fun!
On Mac OS XCode is an option.
On startup:
New Application -> Command Line Tool ->Type C
And Bob is your proverbial (aunty).
You get all the XCode short cuts & hit ESC in your editor window for code completion.
Hmmm.... think I'll start using it actually. ;-)
re:

been compiled.
You can get immediate feedback on syntax errors. They show up as question marks in the left gutter and yellow squiggly lines under the error. This happens immediately. Make sure under Window->Preferences-General->Editors->Text Editors->Annotations that you have the "Show in" checkboxes checked for the C/C++ Indexer Markers and C/C++ Occurrences.
