• Python File Tagging System does not retrieve nested dictionaries in dictionary

  I am building a file tagging system using Python. The idea is simple. Given a directory of files (and files within subdirectories), I want to filter them out using a filter input and tag those files with a word or a phrase.

  If I got the following contents in my current directory:

  data/
     budget.xls
     world_building_budget.txt
  a.txt
  b.exe
  hello_world.dat
  world_builder.spec
  

  and I execute the following command in the shell:

  py -3 tag_tool.py -filter=world -tag="World-Building Tool"
  

  My output will be:

  These files were tagged with "World-Building Tool":
  data/ world_building_budget.txt
  hello_world.dat
  world_builder.spec
  

  My current output isn't exactly like this but basically, I am converting all files and files within subdirectories into a single dictionary like this:

  def fs_tree_to_dict(path_):
      file_token = ''
      for root, dirs, files in os.walk(path_):
          tree = {d: fs_tree_to_dict(os.path.join(root, d)) for d in dirs}
          tree.update({f: file_token for f in files})
          return tree
  

  Right now, my dictionary looks like this: key:''.

  In the following function, I am turning the empty values '' into empty lists (to hold my tags):

  def empty_str_to_list(d):
      for k,v in d.items():
          if v == '':
              d[k] = []
          elif isinstance(v, dict):
              empty_str_to_list(v)
  

  When I run my entire code, this is my output:

  hello_world.dat ['World-Building Tool']
  world_builder.spec ['World-Building Tool']
  

  But it does not see data/world_building_budget.txt. This is the full dictionary:

  {'data': {'world_building_budget.txt': []},  
  'a.txt': [],
  'hello_world.dat': [], 
  'b.exe': [], 
  'world_builder.spec': []}
  
  

  This is my full code:

  import os, argparse
  
  
  def fs_tree_to_dict(path_):
      file_token = ''
      for root, dirs, files in os.walk(path_):
          tree = {d: fs_tree_to_dict(os.path.join(root, d)) for d in dirs}
          tree.update({f: file_token for f in files})
          return tree
  
  
  def empty_str_to_list(d):
      for k, v in d.items():
          if v == '':
              d[k] = []
          elif isinstance(v, dict):
              empty_str_to_list(v)
  
  
  parser = argparse.ArgumentParser(description="Just an example", formatter_class=argparse.ArgumentDefaultsHelpFormatter)
  
  parser.add_argument("--filter", action="store", help="keyword to filter files")
  parser.add_argument("--tag", action="store", help="a tag phrase to attach to a file")
  parser.add_argument("--get_tagged", action="store", help="retrieve files matching an existing tag")
  
  args = parser.parse_args()
  
  filter = args.filter
  tag = args.tag
  get_tagged = args.get_tagged
  current_dir = os.getcwd()
  
  files_dict = fs_tree_to_dict(current_dir)
  empty_str_to_list(files_dict)
  
  for k, v in files_dict.items():
      if filter in k:
          if v == []:
              v.append(tag)
              print(k, v)
  
          elif isinstance(v, dict):
              empty_str_to_list(v)
  
      if get_tagged in v:
          print(k, v)

• Looping the function if the input is not string

  I'm new to python (first of all) I have a homework to do a function about checking if an item exists in a dictionary or not.

• NextJS: Error serializing `.data.data` returned from `getServerSideProps`

  I'm new to NextJS. I'm working on a simple page in which I need to retrieve data from my backend app. My backend app is a totally separate app written in go. My undestanding is that I must use getServerSideProps to get data from the server on load, so I've got the following:

  myProject/pages/category/new.js:

  export default function AddNewCategory(data) {
  ...
  }
  
  export const getServerSideProps = async () => {
      const data = await getAllCategories();
      console.log(await data)
      return {
          props: {
              data: { data }
          }
      };
  };
  

  myProject/api/category.js:

  import axios from "axios";
  
  // getAllCategories returns a list of all active categories
  export const getAllCategories = async() => {
  
      axios.get("http://127.0.0.1:8080/api/v1/categories")
          .then(function (response) {
              console.log(response.data)
              return response.data;
          })
          .catch(error => {
              console.error("error")
              console.log(error)
          })
  
  }
  

  As you can see I've got a print statement in getAllCategories which prints:

  {
    data: [
      {
        id: 1,
        name: 'Pop',
        slug: 'pop',
        description: 'Pop',
        parent: 0,
        active: true,
        created_at: '2022-05-03T19:50:00-04:00',
        updated_at: '2022-05-03T19:50:00-04:00',
        deleted_at: null
      },
      {
        id: 3,
        name: 'Pop 2',
        slug: 'pop-2',
        description: 'Pop',
        parent: 0,
        active: true,
        created_at: '2022-05-03T19:50:24-04:00',
        updated_at: '2022-05-03T19:50:24-04:00',
        deleted_at: null
      }
    ]
  }
  

  yet I'm getting the following error:

  error - Error: Error serializing .data.data returned from getServerSideProps in "/category/new". Reason: undefined cannot be serialized as JSON. Please use null or omit this value.

  I saw around that I should try to convert the data to string and then back to json:

  return { 
    props: { 
      data: JSON.parse(JSON.stringify(data)) 
    } 
  };
  

  but when I do this I'm getting a different error:

  error - SyntaxError: Unexpected token u in JSON at position 0

  I'm using next@12.1.5

  Any idea what's going on?
• Appending values to existing values of environment variables in go

  How can I append another value to an existing value of a go environment variable?

  If CGO_CXXFLAGS has the value "-I/blah/blah"

  Since the following doesn't work

  $ go env -w CGO_CXXFLAGS="$CGO_CXXFLAGS -I/foo/bar"
  

  I want to find a proper way to CGO_CXXFLAGS have the value "-I/blah/blah -I/foo/bar"

  by avoiding to simply re-set all the values plus the new one, such as in:

  $ go env -w CGO_CXXFLAGS="-I/blah/blah -I/foo/bar"

• How do you use mktemp to create directory in Makefile?

  edit:

  Solved by awesome answer below. Expand the variables using := instead of =

  mktemp: TEST:=$(shell mktemp -d)
  mktemp:
      echo $(TEST)
      touch $(TEST)/test.txt
      ls $(TEST)
      cat $(TEST)/test.txt
      rm -rf $(TEST)
  

  original question:

  This is a Makefile piece of code of how someone may use mktemp in a Makefile

  TEST=$(shell mktemp -d)
  mktemp:
      echo $(TEST)
      touch $(TEST)/test.txt
      ls $(TEST)
      cat $(TEST)/test.txt
      rm -rf $(TEST)
  

  This is an example output

  ❯ make mktemp 
  echo /var/folders/62/wkysd_4n0w57ljl9ycfsd9cc0000gn/T/tmp.tQI5EeyW
  /var/folders/62/wkysd_4n0w57ljl9ycfsd9cc0000gn/T/tmp.tQI5EeyW
  touch /var/folders/62/wkysd_4n0w57ljl9ycfsd9cc0000gn/T/tmp.lVL3N8Rp/test.txt
  ls /var/folders/62/wkysd_4n0w57ljl9ycfsd9cc0000gn/T/tmp.sBW9FzgD
  cat /var/folders/62/wkysd_4n0w57ljl9ycfsd9cc0000gn/T/tmp.Ti53SWSw/test.txt
  cat: /var/folders/62/wkysd_4n0w57ljl9ycfsd9cc0000gn/T/tmp.Ti53SWSw/test.txt: No such file or directory
  make: *** [mktemp] Error 1
  

  The expectation is that cat /var/folders/62/wkysd_4n0w57ljl9ycfsd9cc0000gn/T/tmp.Ti53SWSw/test.txt would not error.

  How can mktemp be used in this case?
• "Core Dump" analogue for Python scripts?

  Say, my script runs on server and has failed at some moment of time.

  Except for the error messages in the logs - I would like to have some image file on server side - representing the state of python process in the moment of failure.

  I would be able then to move it to my local machine, load into debugger, examine the call stack and what data in what function did really cause the exception.

  Is there a way to do that?
• How do I position Eclipse type hierarchy while editing

  Eclipse for Windows 64-bit machine - Version: 2022-03 (4.23.0).

  I am used to having the Type Hierarchy (?) in a tab on the right side of my screen. It was like that through a number of Eclipse releases, and it worked for me! I seem to have lost that, and can't seem to get it back!

  Now the nearest I can get to that layout is to do CTL-O, but the methods are in alphabetical order, and I can't seem to get the display over to the right side of the screen (alpha order is sort of OK - I am not keen on it, but it's better than nothing!). Plus it seems to be a popup, and doesn't last long enough! I have seen posts saying I can grab the CTL-O (?) tab and drag it over, but I can't find the tab.

  It's probably something dumb, but I can't figure it out! Maybe a more general question would be: what's the best tool in Eclipse for navigating around a complex type hierarchy? Help would be appreciated!
• How to set, list, get breakpoints in classdef in octave?

  Suppose I have a classdef in a MyClass.m file with properties and methods like in the polynomial2 example found here https://octave.org/doc/v7.1.0/Creating-a-classdef-Class.html

  I've confirmed that it's possible to set breakpoints in class methods using

  dbstop in MyClass at MyClassMethod
  

  as described here https://octave.org/doc/v7.1.0/Breakpoints.html

  My questions are:

  Is it possible to use a line number instead of the method name?

  Is is possible to list the breakpoints in the class file?

  Is it possible to clear breakpoints only in that class file?

  Since all of the above are possible for functions, I would suppose it should also be possible for classes.

  Thank you
• Is it possible to use input variables in keybindings in VS Codium?

  In Visual Studio Codium I want to define a command that has a variable parameter.

  I want the IDE to open specific file, which name is written in another file. Assume I have the following project structure:

  /home/user/myproject/
  /home/user/myproject/dir1/
  /home/user/myproject/dir1/problem1.py
  /home/user/myproject/dir1/problem2.py
  /home/user/myproject/dir2/problem1.py
  ...
  /home/user/myproject/pointer.txt
  

  The pointer.txt contains path to the file I want to work on. For example, it contains: dir1/problem1.

  I have read the documentation here. Now I created the following construction:

  keybindings.json:

      {
          "key": "numpad3",
          "command": "htmlRelatedLinks.openFile",
          "args": {
              "file": "${workspaceFolder}/${input:mycatinput}.py",
              "method": "vscode.open",
              "viewColumn": 2,
          }
      },
  

  tasks.json:

  {
      "version": "2.0.0",
      "tasks": [
          {
              "label": "mycat",
              "type": "shell",
              "command": "cat /home/user/myproject/pointer.txt"
          },
      ],
      "inputs": [
          {
            "id": "mycatinput",
            "type": "command",
            "command": "workbench.action.tasks.runTask",
            "args": "mycat"
          }
      ]
  }
  

  But when I press numpad3, I get an error notification with text: Unable to open '${input:mycatinput}.py': File not found.

  Am I missing something? How do I specify a variable in keybindings.json command, which itself is a result of another command (a shell command, not a vscode command).
• Can I use multiple different commands for a single file type in coderunner?

  "code-runner.executorMap": {

  Coderunner has a command to run .cpp code, but if I want to use another command, such as adding " < input.txt", I would have to go to settings.json to change it. Is there a way to set up multiple commands on vscode for a single kind of file so I can just simply switch without having to change settings.json?
• How do I set the default c# file in my Visual Studio Code c# Project?

  I am new to using Visual Studio Code. I have always used Visual Studio IDE in Windows. I am trying to run a simple Hello World Program on Mac with VS Code. I ran the following command

  dotnet new console

  which successfully created the csProj file and Program.cs file with the code Console.WriteLine("Hello, World!"); Now by issuing dotnet run command I can get the output from this Program as well. But I have a different cs file called "Hello.cs" in the same Project location. How do I get the Hello.cs to run instead of the default "Program.cs" created by dotnet new console command. I tried giving the following property group in the .csproj file but VS Code reports error this is reserved property.

  <PropertyGroup><StartupObject>Hello.HelloWorld</StartupObject></PropertyGroup>
  

  Is there another way to choose your default startup CS File if you have multiple CS files in your Project.
