Powershell 5 PSReadLine autocompletion how to ignore batch files (.cmd/.bat) - powershell

I use auto-complete heavily...
When I invoke the auto-completion with tab key...
Powershell also includes any files from the current folder
or in the current path in the autocomplete list
How can I configure Powershell to ignore these files
(eg. auto-complete only with Powershell commands/functions)

There is no simple way to get the behavior you're looking for.
At best, you can define your own function named TabExpansion2 and either fully implement tab completion yourself (definitely not recommended) or filter the results returned from the default implementation of TabExpansion2.
I recall discussing this idea recently, I thought there might even be an open issue, but I didn't see it after a quick search here.
I don't know the exact history, but at one point we did implement the behavior you're wanting. It did break some tests, and I think some people preferred seeing effectively useless completions over no completions, perhaps it was reassuring that completions were still working.
At any rate, I think it's a reasonable feature request, I'd suggestion opening an issue if you can't find one.

How to make VSCode's python debugger skip stepping into some modules when debugging

In vscode's python (ms-python) extension, is there a way to make the debugger (debugpy) not to step-into functions defined in specific modules. I have found justMyCode but it will skip entering into external modules only (like members of stdlib) while I need to skip my own modules sometimes.
I saw some debug adaptors for some other languages implement skipFiles property. Is there anything similar for python?
Going thru debugpy code I found this undocumented feature which works like a charm: in launch.json's debug configuration add
"rules" : [{"module":"*xxx*", "include":false}]. Make sure the xxx is the full module name like a.b.module
There are more working options. They can be seen here
A word of warning. This feature is undocumented (at least I did not find it anywhere) so use with caution as it might disappear one day. At the other hand, this feature is properly tested as part of the code uni-testing (as you can see from the link)

VSC command palette (too narrow)

Is there any possibility to make command palette wider?
When looking for symbol (e.g. same functions with different set of arguments) to less characters are shown to choose proper definition.
Is there any possibility to mitigate this problem?
Using standard VS Code settings looks like you can't do this, which I agree should be possible. The strange thing is that I can't find an extension too that does this, so there may be a specific reason why this can't be done at the moment. By the way you can open an Issue on the VSCode Github and ask the developers themself to add this feature or why seems to be missing at the moment

Eclipse equivalent of CTRL-K in Netbeans

Netbeans has a nifty shortcut completion, I use while I type. It works in comments, in strings. Pretty much places where regular completion is useless. It basically autocompletes using the editor scope (in other words, whatever word matches closes to the point you are typing). Is there something similar in Eclipse ? I am making a transition due to lack of mybatis/mylyn support in netbeans. You can read more about it here https://blogs.oracle.com/chengfang/entry/why_am_i_using_netbeans .
It's called Word Completion. The key binding may vary; Ctrl/Cmd+Shift+L to find out.
CTRL+Space will show and sometimes autocomplete (depends on the settings you choose) methods names, variables and etc.
You can read more about specific settings and further fine tuning here.

How should I provide help for a related set of functions?

I built tfs.el to allow developers to do TFS things (checkout, checkin, etc) from within emacs.
There are 13 interactive commands in the tfs package, like tfs/checkout, tfs/rename, tfs/diff, and so on, and I'd like to be able to provide help on all of them in a single place. An overview of all the available functions.
What's the "emacs way" of doing that? I thought of defining an additional function, like tfs/help , that would invoke describe-function-1 on each of the tfs functions, and then present all that in a TFS-Help buffer.
Is there a better way?
Well, there are many "Emacs way"s.
The most polished would be to write an info page, see the page "Info for Experts", which basically says to use Texinfo and convert that into an info page. You can be as verbose as you want there, and the user can search, use hyperlinks, etc. The user can easily get there via C-h F tfs/checkout.
Another way some folks seem to do it is to write short documentation strings for each of the commands, ending with "see documentation for tfs-mode for details" and put all the common documentation in the docstring for tfs-mode.
Another way some packages document things is with a big comment at the top of the tfs.el file.
Take your pick, they all have trade-offs.
You can use
(describe-bindings "\C-xv")
You have multiple, related commands. So far, I guess, they are related only by their names.
Two possibilities come to mind:
Create a mode for this stuff. Document everything in the doc string of the command that turns the mode on/off. It could be a major mode or a minor mode. If a minor mode it could be buffer-local or global.
Create a group (defgroup) for this stuff and document everything in its doc string.
The basic idea is to somehow actually relate these commands: bundle them together in some way, so you can document them together as the doc for the bundle.
Offhand, without knowing more, my guess is that you might want to create a global minor mode.

powershell.exe tab completion - list alternatives?

I've never really used PowerShell before, and playing with it a bit, it looks like it uses cmd.exe's style of tab completion (fill in the first likely candidate, and then you can use tab to cycle through other alternatives). I'd much prefer the way e.g. bash works, where if there are multiple candidates, it shows a list of them.
Is there an easy way to turn this on, by any chance?
I have seen this implemented with an add-on called PowerTab (original post). For script editing there are some editors that support this sort of drop down Intellisense. Check out the free PowerGUI editor.
You want PSReadline: https://github.com/lzybkr/psreadline
It includes many completion and shell experiences you might expect from bash, etc.
