Codename One: How to put a line break in a build hint? - codenameone

I would like to extend my info.plist by
<key>NSLocationWhenInUseUsageDescription</key>
<string> first line
second line</string>
but I don't know how to apply this to the respective build hint (ios.plistInject). Note: the line break is relevant.

That particular build hint can be added using the ios.NSLocationWhenInUseUsageDescription (See the advanced topics section of the developer guide and do a find for "UsageDescription").
In general, if you copy and paste a build hint into Codename One Settings that includes line breaks, the line breaks will be retained.

Is there a way to get help for some C functions inside of vim/Neovim?

This question may be a little off topic. But I was wondering if there was a way for me to look at the descriptions of C functions using vim or neovim. Is it possible to look at their documentations by doing something like :help? This would really be helpful since I wouldn't need to lookup to my browser everytime.
I am unclear about these things:
Can :help be my friend here ?
Can I use LSPs to do something like this ?
I am using latest Neovim inside Ubunutu 20.04 in WSL. Is this helpful somehow ?
By pressing K, the keyword under the cursor is looked up using a configured keyword lookup program, the default being man. This works pretty much out of the box for the C standard library.
For C++, you might want to look at something like cppman.
Well yes, you can get the description of C functions by using a LSP (language server plugin)! Here is an image of me using clangd as my LSP:
You'd "just" need to install the LSP and start it. I don't know how familiar you're with neovim, but just in case if you don't know how to install a plugin or to be more specifique: If you don't know how you can install a LSP server, then you can do the following:
There're plenty videos how to set up a LSP-Server for your language. Here's an example.
If you don't want to set up on your own, you can pick up one of the preconfigured neovim setups (some of my friends are recommending lunarvim)
But yeah, that's it. If you have any further questions feel free to ask them in the comments.
Happy vimming c(^-^)c
Let's explain how "K" command works in more detail.
You can run external commands by prefixing them with :! command. So running man tool is as easy as
:!man <C-R><C-W>
Here <C-R><C-W> is a special key combination used to put word under cursor from text buffer down to command line.
Same for showing Vim's built-in help page
:help <C-R><C-W>
As it feels tedious to type that, Vim also defines K Normal mode command that does pretty much the same thing. Except the tool name is taken from value of an option named "keywordprg".
So doing set keywordprg=man (default for *nix systems) makes K to invoke !man tool; while set keywordprg=:help is for bultin help.
Also, the option :h 'keywordprg' is made global or local-to-buffer, so any Vim buffer is able to overwrite global setting. For example, this is already done by standard runtime for "vim" and "help" buffers, so they call ":help" instead of "man".
The problem with :!man command is that it shows "black console". It'd be nice if we could capture man's output and open it inside Vim just like a builtin help page. Then we could also apply some pretty highlighting, assign key macros and all such. This is a pretty common trick and it is already done by a standard plugin shipped with Vim/Neovim.
A command that the plugin provides is called :Man, so you can open :Man man instead of :!man man, for example. The plugin is preactivated in Neovim; for Vim you still need to source one file manually. So to make use of this plugin you'll need something like this
set keywordprg=:Man
if !has("nvim")
source $VIMRUNTIME/ftplugin/man.vim
endif
The previous answer recommending cppman is the way to go. There is no need to install a bulky language server just for the purpose of having the hover functionality. However, make sure you're caching the man pages via cppman -c. Otherwise, there will be a noticeable delay since cppman is fetching the page from cppreference.com on the fly.
If you like popups for displaying documentation, convert the uncompressed man pages (groff -t -e -mandoc -Tascii <man-page> | col -bx), and set keywordprg to your own wrapper to search for keywords according to your needs.

Eclipse CDT: Mapping console output to source file and line

While debugging code it helps to have source filename and line number on console output. I already use FILE and LINE macros. But it would be great if double clicking a line in the console output would take me to the exact source line which was responsible for outputting that line of log. Can eclipse parse console output and do something like this? It need not work all the time, only when the log line is in a specific format and the source filename and line number are valid.
It's possible to use a workaround if you add the pydev plugin and a few lines of python to call your main function. You can find the needed code here: https://github.com/oct15demo/python_calls_cpp
As noted there, I posted a query on the Eclipse forum to find out the status of any ongoing effort or obstacles to implement within Eclipse.
I could not find out any further information on the feature, if it's there, it's well hidden.
Update March 17, 2022, I shall be working on the feature for Eclipse, don't have an estimate of time yet.

NHunspell - How to generate all recognized words?

Is it possible with NHunspell to generate the list of all recognized/valid words? As far as I remember it was possible with hunspell (unmunch) from the command line.
From current hunspell documentation:
munch: dictionary generation from vocabularies (it needs an affix file, too).
unmunch: list all recognized words of a MySpell dictionary
wordforms: word generation (Hunspell version of unmunch)
No, that is not possible with NHunspell at the moment because it isn't part of the Hunspell library but only the Hunspell command line tool. I've implemented nearly all functions of the Hunspell library in NHunspell, but not all command line tools. If you want it implemented please suggest this feature in the NHunspell forum:

Vim autocomplete from ctags for system headers only works when popup is triggered manually

On OS X, I generated a set of ctags for the system includes using the following command:
ctags -f c -h ".h" -R --c-kinds=+p --fields=+iaS --extra=+q /usr/include
This was run inside of a ~/.vim/ctags/ directory, where I put all of the ctags I generate for system-wide header files (I also have stuff for ROS and CPP that I load conditionally, but that's neither here nor there).
Anyway. The ctags file is set correctly in my .vimrc, and vim can definitely see the ctags, but for some reason the autocomplete popup will only display results from #included header files if I write out the entire symbol and then start backspacing. As an example, if I #include <string.h> in a project, and then I want to call strlen(), and I start to type str in to the active vim buffer, I will only get results for symbols that are currently in the vim buffer. But, if I type out strlen and then start backspacing one or two characters and hit <C-n>, the popup menu will be populated with matches from any other included header files.
EDIT: Turns out, if I just hit "s" then <C-n>, it works as well. So the problem seems to be that it only works if the popup menu is launched manually. Which makes me think that it's a plugin problem (see below)
Additional information:
completeopt is set to completeopt=menuone,menu,preview,longest
I have OmniCppComplete, which I suppose could be interfering with the behavior. It is currently not being conditionally loaded for C++ files only. If you want me to edit and post my OmniCppComplete settings from my .vimrc, just ask.
I also have AutoComplPop installed, but I haven't done anything to configure it, so it's running with its default settings. Haven't really researched the plugin, so no idea if some of it's behavior could be interfering with the results.
I have AutoTag and TagBar installed, but those should only be fiddling with the current directory's local tagfile.
I'm honestly pretty new to Vim, and I just have no idea where to start debugging this issue, whether it be with a random plugin or with my .vimrc settings.
Vim has many specific completion mechanisms.
<C-n> and <C-p> use many sources defined by the complete option. By default, they will provide completion using the current and all loaded and unloaded buffers, tags and included files. While you can usually get quite useful suggestions with these, it is a bit of a "catch-all" solution: it is not reliable at all if you work on reasonably large projects.
<C-x><C-]> uses only tags so it may be a little more useful to you.
And there are many more, see :h ins-completion.
Omni completion is smarter: it typically runs a custom filetype-specific script that tries hard to provide meaningful completion. It is triggered by <C-x><C-o> and you can read about it in :h ft-c-omni. Omni completion is often a better choice when working with code.
Because you have two overlaping "auto"-completion plugins it's hard to say what completion mechanism is at work. You should disable those plugins and play around with the different completion mechanisms available to you.
I have not mastered this yet, but I do think the following observation may be of help.
Vim's default auto complete which can be quite noisy, often gets in the way of what you call with <C-x><C-o>. Specifically, I found myself calling up my tags based completions with <C-x><C-o> only to have them replaced with continued typing with Vim's default suggestions using my open buffers.
The suggestion of shutting off one of the plugins makes sense. In my case the key was how to shut down Vim's default behavior. I have seen several people (and to which I now include myself), set the length of the expression to a high number before triggering Vim's default. For me that is:
let g:deoplete#auto_complete_start_length = 99
... this way you eliminate the default layer of completions that comes and goes regardless of the commands you intended to inform your work.
This still feels like a hack but it helps keep my work focused on the tag-based completions.
FYI: I use NVIM on a Mac.

How to break words into syllables in LaTeX correctly

I am writing my MSc with LaTeX and I have the problem that sometimes my words are divided in a wrong way.
My language is spanish and I'm using babel package.
How could I solve it?
For example: propuestos appears prop-uestos (uestos in next line). It should be pro-puestos.
Thanks!!
If you only have a small number of hyphenation errors to correct, you can use \hyphenation to fix them. For instance: \hyphenation{pro-puestos}. This command goes after \documentclass and before \begin{document}.
You can put more than one dash in, if you want to give TeX more line-breaking options: \hyphenation{tele-mun-dos}. You can list many words inside the braces; put spaces between them.
If more than a handful of words are wrong, though, TeX is probably using hyphenation patterns for the wrong language -- and if "propuestos" were an English word, it would be hyphenated after "prop", so that's another point in favor of that theory. Do you get a message like this when you run LaTeX?
Package babel Warning: No hyphenation patterns were loaded for
(babel) the language `Spanish'
(babel) I will use the patterns loaded for \language=0 instead.
If so you need to reconfigure your TeX installation with Spanish hyphenation turned on. There should be instructions for that in the manuals that came with the installation. Unfortunately, this is one of the places where TeX's age shows through -- you can't just load a package with the proper hyphenation rules (or Babel would do that); you have to do it when compiling the "base format" with INITEX, which is a maintenance operation. Modern TeX installations have nice utilities for that but they're all different and I don't know which one you're using.
