问题 I have bought a soundcard: Focusrite Scarlett 4i4 3rd Gen , with 4 outputs channels. I also have 4 speakers and I will link each speaker with the soundcard. I would like to be able to set separately the volume of each speaker, with maybe a tkinter interface (ultimately, but that is not the point). I have seen that we could have plenty of different librairies (I'm using windows 10 for this project): the ones that seems to be interesting are sounddevice and soundcard. I would though like to

问题 I'm using Vim's surround and repeat plugins to wrap lines of text with html tags. I'll use "yse<p>" and "ys$<p>", they both work fine. I try to repeat the command with ".", and it shows <p> in the terminal, but whenever I press enter to execute the command, surround replaces what should be <p> and </p> with ^M. My line looks like ^Mtext here^M I recognize the character as a line ending, but I don't understand why surround won't wrap my line with the code it shows in the terminal (which is

问题 How would one write a regex that matches a pattern that can contain quotes, but if it does, must have matching quotes at the beginning and end? "?(pattern)"? Will not work because it will allow patterns that begin with a quote but don't end with one. "(pattern)"|(pattern) Will work, but is repetitive. Is there a better way to do that without repeating the pattern? 回答1: You can get a solution without repeating by making use of backreferences and conditionals: /^(")?(pattern)(?(1)\1|)$/ Matches

问题 How can I insert empty ERB tags and put cursor inside it? It is similar to surrounding with surround plugin, but there is nothing to surround. For example, from this: bla|bla I want get this: bla<%= | %>bla 回答1: I would use Tim Pope's surround plugin to accomplish this.

问题 This is the example table: Column | 1st record | 2nd record | 3rd record | 4th record | etc<br /> id (primary) | 1 | 5 | 8 | 12 | etc<br /> name | name 1 | name 2 | name 3 | name 4 | etc<br /> date | date 1 | date 2 | date 3 | date 4 | etc<br /> callValue (unique) | val1 | val2 | val3 | val4 | etc I select one row that is the data to show (for example: row with callValue: val3). But I cannot find a solution for this: I need to select previous and next row. So, in this example, I need to get

问题 Did anybody get surround.vim to work with repeat.vim? This should enable you to repeat any command provided by the surround plugin with the "." command. I think surround.vim should already have builtin support for the repeat plugin, so it should work out of the box but I can't get it to work. 回答1: I just put surround.vim and repeat.vim in my .vim/plugins folder and tried it out. For me, it works like described. May you try the repeat command on a function that is not supported. In the docs of

I can do this with visual mode but would like to do something I can repeat with the dot operator. Any advice? 回答1: You want repeat.vim which adds . support to several other plugins, including surround. 回答2: From normal mode try to record a macro. Then: qai
