QUESTION
In nodejs, when we run console.log({a: 3})
, we get a nice colored output, with the 3
being colored brown.
How can we get the raw colored output of console.log to stdout?
...ANSWER
Answered 2021-Jun-01 at 23:49You're looking for the colors
option to util.inspect
that node's console.log
uses internally:
colors
If
true
, the output is styled with ANSI color codes. Colors are customizable. See Customizingutil.inspect
colors. Default:false
.
Or maybe you just want to instantiate your own Console
, which offers an option for this as well:
colorMode
|
Set color support for thisConsole
instance. Setting totrue
enables coloring while inspecting values. Setting tofalse
disables coloring while inspecting values. Setting to'auto'
makes color support depend on the value of theisTTY
property and the value returned bygetColorDepth()
on the respective stream. This option can not be used, ifinspectOptions.colors
is set as well. Default:'auto'
.
QUESTION
I just want to be able to include xterm.js and the addon, and it should work. But I am totally lost on how to import the attach xterm-addon-attach in my index.html
as a script.
They mention to import the libs via ES6 which give me various errors like: “Can’t find "Terminal
" in xterm.js
”. I put the import statements in another .js
file, and sourced that in my HTML code with the type="module"
attribute, but I get that error.
Wasted a few hours on this, and I’m afraid this is probably simple to do and I’m just missing something simple.
Can anyone help me understand how to get past this and use xterm and the attach addon? Just using xterm alone is fine.
Here’s the loadxterm.js

ANSWER
Answered 2021-May-12 at 10:45As of v4 xterm.js does not yet expose ES6 module interfaces in its bundles (planned for v5). The import
mentioned in the guide is a bit misleading in this regard (dont want to bore you with the details, just this - it addresses Typescript's import, which currently gets transpiled to require
due to internal project settings). I admit that the guide could be more clear about that.
Until ES6 exports, what do the bundles actually contain?
Good old vanilla JS definitions on top level, thus they are meant to work with normal

xterm-addon-xy.js
Individual addon bundles exposing all addon exports under a separate namespace. The namespace name is the same as the addon constructor, e.g.:
QUESTION
I'm trying to figure out why dockerode stream directs all data written to the stream directly to the output of the stream.
This is how I create the container, I call the .write()
method on the this.stream
object.
ANSWER
Answered 2021-Apr-08 at 04:42Okay, my current hack to solve this problem is to only read every other on("data", ...)
response. I noticed that the data listener is called twice, once for the command I wrote and the next for the actual output from the shell. So reading every other response prevents this echo. Still looking for a better solution though.
QUESTION
I have an extension that replaces the UTM parameter in URLs with the string WTTDOTM
. It works by having a number of rulesets, each with an individual regexSubstitution rule. I did it this way because if I have multiple rules trying to do a regex substitution in the same ruleset, only one seems to execute (this will be relevant in a bit).
Here is one of the rules. I am wondering if there is a way to collect a user input and have the json reference that input, so that instead of "regexSubstitution": "\\1WTTDOTM\\2"
the rule is changed to "regexSubstitution": "\\1[USER_INPUT]\\2"
.

Answered 2021-Mar-30 at 16:46Use a transform
action for the query part, not regexSubstitution
, and a condition that matches all the parameters.
QUESTION
I'm trying to create a web page where the user will press a button, and it will send some code presented in a div to the terminal which will be executed, I would then want the live output of that code to be displayed in a terminal like window on my page.
I have looked at some ways to do this but haven't really found anything that allows this type of use case.
I saw a way a terminal can be displayed on a webpage as mentioned here using xterm.js but there doesn't seem to be much documentation as to how to link this with an actual terminal to display live output. However, I'd assume it is done via some form of web sockets to capture the output.
I have also seen ways on how to send commands to a terminal using child_process.exec in node.js but I'm struggling to find anything to link the two together.
I don't want the users to be able to interact or run code from the terminal window on the page I would just like it to show the output of the code when they press the button.
Does anyone know of any technologies that could facilitate this kind of use case? Possibly something in Python but my webpage currently uses html and javascript. I understand this won't be possible with just client side code and I will need a server side langauge but preferably something that intergrates with javascript nicely.
Thanks

QUESTION
Struggling to get using xtermjs, and have some questions which aren't covered in the official documentation, at least I didn't find.
- I understand that when I use some app within the terminal, for example, Vim terminal need to be switched to alternate buffer, after I quit from the app, terminal switched back to the normal buffer. Is this right?
- To switch between buffers (and overall to control terminal behavior) I need to use a control sequence. It isn't something unique to xterm.js, but the common pattern and control sequence is unified between terminals?
- Control sequence to switch to the alternate buffer is
CSI ? Pm h
with parameter47
according to documentation:
DECSET DEC Private Set Mode CSI ? Pm h Set various terminal attributes.
Where
paramAction
47 - Use Alternate Screen Buffer.
- How to use this control sequence with xterm.js, for example, I want to switch to alternate buffer. What string should be used in
terminal.write(...)
?
ANSWER
Answered 2020-Aug-21 at 16:34Yes, see description here in this question Using the “alternate screen” in a bash script
The alternate screen is used by many "user-interactive" terminal applications like vim, htop, screen, alsamixer, less, ... It is like a different buffer of the terminal content, which disappears when the application exits, so the whole terminal gets restored and it looks like the application hasn't output anything
Yes, ANSI escape code
ANSI escape sequences are a standard for in-band signaling to control the cursor location, color, and other options on video text terminals and terminal emulators. Certain sequences of bytes, most starting with Esc (ASCII character 27) and '[', are embedded into the text, which the terminal looks for and interprets as commands, not as character codes.

CSI ? 47 h

CSI ? 47 l

QUESTION
I am trying to develop a "console" in pyqt. Similar to xterm.js where all the console is, is front end it does not spawn any sub-processes its just an I/O for me to plug in whatever I want to at a later date.
are there any existing python packages or simple widgets I can use that would allow me to put a terminal like interface within my pyqt application?
its a client server application so the terminal is used to send commands to the backend server and retrieve output as if it were a bash shell (for example)
...ANSWER
Answered 2020-Jun-12 at 22:12You can use QTermWidget (if you can't install it and you're using ubuntu then you can check this answer).
For example a translation of the official RemoteTerm example that allows to access the shell remotely through sockets would be the following:
