I am having issues trying to map <C-S> in Vim terminal.
The same mapping works in MacVim/gVim but not in the terminal. I have tried the below mappings in Terminal.app and the latest version of iterm2 and it fails to work.
Is using <C-S> a bad idea because of terminal issues? If it is I was not aware (and could not find any information about it.
nnoremap <script> <buffer><C-s> :call <sid>MyPrivateFunction()<CR>
Note though that the above mapping works in MacVim/gVim but not in the terminal.
I have also tried the following variations:
cmap <script> <buffer><C-s> call <sid>MyPrivateFunction()<CR>
map <script> <buffer><C-s> :call <sid>MyPrivateFunction()<CR>
nnoremap <C-s> :call MyFunction()<CR>
Am I doing something wrong? And again, is it a bad idea to issue such a mapping? What would be the alternative?
<C-s> and <C-q> have been used for decades to do software flow control. You'll probably want to avoid mapping those key sequences in general.

I'm trying to run Neovim 0.8.1. on a Windows 11 environment.
My setup is really minimal:
I downloaded nvim-win64.zip (of version 0.8.1) from Neovim's releases page on Github.
Extracted it and moved it to a folder at C:\test\nvim-win64
Started up Neovim by executing C:\test\nvim-win64\bin\nvim.exe
Not using any custom config.
When inspecting my runtimepath, there are 2 ways of doing this:
Using :set runtimepath? (the Vimscript way). This gives me:
runtimepath=~\AppData\Local\nvim,~\AppData\Local\nvim-data\site,C:\test\nvim-win64\share\nvim\runtime,C:\test\nvim-win64\share\nvim\runtime\pack\dist\opt\matchit,C:\test\nvim-win64\lib\nvim,~\AppData\Local\nvim-data\site\after,~\AppData\Local\nvim\after
Using :lua print(vim.inspect(vim.api.nvim_list_runtime_paths())) (the Lua way). this gives me:
{ "C:\\test\\nvim-win64\\share\\nvim\\runtime", "C:\\test\\nvim-win64\\share\\nvim\\runtime\\pack\\dist\\opt\\matchit", "C:\\test\\nvim-win64\\lib\\nvim" }
As you can see, it seems like using the Lua way I'm missing the local config directories in my runtimepath (the ~\AppData\Local\* paths).
Why am I seeing this difference? This is blocking me from using XDG_CONFIG_HOME to use my own config that I typically use, because it seems like it does not get included in the nvim_list_runtime_paths list, but it does appear in :set runtimepath?.
Nvim api function filters out non-existent directories. So there's a difference.
My issue was that my employer had decided to put ( and ) characters in my %USERPROFILE% environment variable, which ended up breaking a bunch of stuff (including the list I got from nvim_list_runtime_paths).
Putting those characters in %USERPROFILE% is a bad idea for many reasons, so I moved all of my files and folders out of any (sub)directory in %USERPROFILE% and right in C:\.
I also had to define XDG_CONFIG_HOME, XDG_DATA_HOME and XDG_STATE_HOME to point to a different location than the default location (which default within %USERPROFILE%).
This made all of my troubles go away!
When you compile a SDK using bitbake and have to source like :
source /opt/poky/.../environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
It can't be accomplished through fish, which is expected as the export sintaxe is different (i.e. set -x ...). I tried even to add #!/bin/bash on the first line, which also doesn't work. Does anyone knows a good way for it?
Workaround: Nowadays I run a bash inside the fish prompt to be able to compile binaries, which is not the best way but works. Don't let those small things push oyu away from fish :)
#charego mentioned some good ideas, thanks! :)
Fish-bax
So you can run it as:
bax 'source /opt/poky/.../environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi'
The only down side is that the auto completion does not work inside quotes, so one will need to write the whole path to the file. Although it's still better to have a fish running on top of a bash.
Bass
Bass did not worked, as it crashs with: Fatal Python error: Py_Initialize: Unable to get the locale encoding ImportError: No module named 'encodings'
Foreign-env
Foreign-env also didn't work. It's possible to to set the variable, although it threw warning:
warning: include location "/usr/local/include" is unsafe for cross-compilation [-Wpoison-system-directories]
and it does not compiles, probably it misses a few variables to export.
TL;DR Go with Fish-bax, at least it works :)
Context
So I finally give a try to Fish, and as one would expect I encounter some frictions due to differences with my usual routines.
The most astonishing for me, as for many other, was the absence of the bang operator. I'm fine with the lose of sudo !!, as the suggested function replacement seems even better to me, I named it gar which means "To make, compel (someone to do something); to cause (something to be done." However I'll need a replacement for !<abc><enter> which grab the last history line starting with <abc> and run it without further ado, suggestions are welcome.
Now, for the more personal things:
- I use a Typematrix 2030 keyboard
- I use a bépo layout
- I like to configure default finger position keys with the most used actions
Aims
As on my keybord <enter> is well positioned and is semantically relevant for that, ideally I would like to achieve the following key binding:
ctrl-enter: accept the whole suggestion and run it without further confirmation
ctrl-tab: accept the whole suggestion and wait for further edit
alt-enter: redo the last command without further confirmation
But according to xev it appears that, at least with Gnome-terminal, this combinations are not recognized. Are they terminal that supports it? For now I remapped these three to <ctrl>-i, <alt>-i and <alt>-I respectively:
bind --preset \ci forward-char execute
bind --preset \ei forward-char
bind --preset \eI forward-word
This works as expected, but it seems that now the tab key will also map to the first item. I guess that tab map to <alt>-i at some point in the shell stack. I wasn't aware of that, so I don't know yet if it will be possible for Fish to separate each of them.
To manage jobs, I also came with
bind --preset \es fg
bind --preset \eS bg
The first works as expected, but the second one doesn't. With application like vim, the binding should be operated in the application configuration itself of course. But for things as trivial as yes, <alt>-S won't work as expected while <crl>-z continue to operate normally.
I also would like to bind some commands like ls -alh and git status --short to a directly executed command, showing the result bellow the currently edited line, allowing to further type seamlessly, but didn't find the way to do it yet.
Summary of remaining question
So here are my more precise questions summarised:
how do I bind the sleep signal to <alt>-S?
is there a terminal I can use where <alt>-<enter> and <ctrl>-<enter> works?
how to seamlessly run command while maintaining the current line edition in place?
can you bind something to <alt>-i without altering <tab>?
how do I bind the sleep signal to -S?
What you are doing with bind \es fg is to alter a binding inside the shell.
But when you execute yes, the shell isn't currently in the foreground, so shell bindings don't apply.
What you'd have to do instead is change the terminal settings via stty susp \cs,
but fish resets the terminal settings when executing commands (so you can't accidentally break them and end up in an unusable environment), so there currently is no way to do this in fish.
can you bind something to <alt>-i without altering <tab>?
Sure. You bind \ei. Which is escape+i, which is alt-i (because in a terminal alt is escape).
Your problem is with ctrl-i, which in the way terminals encode control+character is tab. The application receives an actual tab character, and at that point the information has been lost.
is there a terminal I can use where - and - works?
Most terminals should send \e\r for alt-enter. ctrl-enter again is unencodable with the usual code (because \r is ctrl-m), just like ctrl-tab is.
Any fix to this requires the terminal to encode these combination differently.
how to seamlessly run command while maintaining the current line edition in place?
I don't know what you mean by this. I'm guessing you want fish to remain open and editable while a command also runs in the foreground. That can't work. There's no way to synchronize output from two commands to a terminal, not with cursor movement being what it is.
I use ubuntu 20.04 with mate (then marco). Up to now (pre-20.04) I could bind Mod4+S to my liking (Win+S). After 20.04 upgrade I discover that this Key shortcut Mod4+S is kinda 'hard-coded' to run mate-search-tool, and my explicit binding from [ControlCenter][Keyboard shortcuts] is not honored (ignored).
The problem exhibit itself as marco spitting the following message
"Failed to execute child process mate-search-tool (No such file or directory)"
Or if I install mate-utils (that I don't need) it run mate-search-tool.
I double checked the decong editor (gsettings) for any hidden 'run-command' mapped on key Mod4+S key but could not find any.
So at the moment I call it an hard-coded key binding.
I'd like to bind Mod4+S, any pointers appreciated.
Cheers
The key seems to be /org/mate/marco/keybinding-commands/command-6.
I didn't find a way to completely disable it but at least if I set the command I want in place of mate-search-tool it works.
It looks, there are multiple keybindings in mate which are not exposed in control center / keyboard shortcuts config. For me, most of them are unwanted. To change or remove them install dconf-editor and go to /org/mate/marco/global-keybindings/ path, where you can find multiple run-command-X keys. To disable them just set disabled string instead of existing keybinding.
I've been learning Ruby/Rails with vim. Tim Pope's rails.vim seems like a really good tool to traverse files with, but I keep getting these pesky "E345 can't find file in path" errors. I'm not vim expert yet, so the solution isn't obvious. Additionally, I've tried this and it doesn't apply to my problem.
As an example of the problem. I have a method format_name defined in app/helpers/application_helper.rb and it is used in app/helpers/messages_helper.rb. Within the latter file I put my cursor over the usage of format_name and then hit gf and I get that error. Similar disfunction with commands like ]f and [f
However, it works sometimes. I was able to gf from user to the app/models/user.rb
Ideas?
I think that is a limitation of rails.vim. It does not support “finding” bare methods. Supporting something like that would require one of the following:
an exhaustive search of all the source files for each “find” request
(which could be expensive with large projects),
“dumb” indexing of method names
(e.g. Exuberant Ctags and gControl-]; see :help g_CTRL-]), or
smart enough parsing of the code to make a good guess where the method might be defined
(which is hard to do properly).
If you know where the method is, you can extend many of the navigation commands with a method name:
:Rhelper application#format_name
But, you do not have to type all of that in. Assuming the cursor is on format_name you can probably just type:RhTabspaceappTab#Control-R Control-W (see :help c_CTRL-R_CTRL-W).
