NorMatrix

check some norm for you

Updates

• Project is moved to https://github.com/X-R-G-B/norma2
• not as good as this repo for now to detect errors, but pretty good good
• but updated with latest norm and new flag option (like explain a certain norm error (like C-01))

install

with pipy

With Pipy

1

• if you want some "stable" version:

pip install normatrix

• if you want the most update to date version:

pip install git+https://github.com/Saverio976/NorMatrix.git

Now you can use it with python3 -m normatrix in your terminal

2

And if you want to just write normatrix :

echo $SHELL

if you are using bash shell (the echo print /something/bash):

echo alias normatrix=\"python3 -m normatrix\" >> $HOME/.bashrc

else if you are using zsh shell (the echo print /something/like/zsh):

echo alias normatrix=\"python3 -m normatrix\" >> $HOME/.zshrc

else if you are using fish shell (the echo print /something/like/fish):

abbr --add 'normatrix' 'python3 -m normatrix'

else handle this yourself bruh;

3

to update it, you just have to run

pip install -U normatrix

4

to uninstall it (sad), run

pip uninstall normatrix

from source

From source

1

git clone https://github.com/Saverio976/NorMatrix.git
cd NorMatrix

Now you can use it with ./path/to/folder/NorMatrix/main.py in your terminal

2

And if you want to just write normatrix :

echo $SHELL

if you are using bash shell (the echo print /something/bash):

echo alias normatrix=\"$PWD/main.py\" >> $HOME/.bashrc

else if you are using zsh shell (the echo print /something/like/zsh):

echo alias normatrix=\"$PWD/main.py\" >> $HOME/.zshrc

else handle this yourself bruh;

3

to update it, just go where you have cloned normatrix run

git pull

4

to uninstall it (sad) Delete the folder

USAGE:
    make -C path/to/NorMatrix PATH_CHECK=$PWD
DESCRIPTION:
    check the norm! in the current working directory
    (call main.py)
ARGS:
    -C path/to/NorMatrix    run the makefile that is in path/to/NorMatrix
                            instead of the one where you are

    PATH_CHECK=$PWD	        check the norm in your current working
                            directory

configuration

you can now configure what functions are banned, and what are not, you can now configure what extension file are banned, and what are not,

all you have to do is put a file .normatrix.json where you execute normatrix

example with nothing banned and no preview (preview = not stable check) check .normatrix.json

{
    "banned": [],
    "no-banned": [],
    "extension": [],
    "no-extension": [],
    "enable-preview": false
}

just add inside [] the string of what you want

other explanation with example

other explanation with example

• to no-banne memset (because you can use it)

{
    "no-banned": ["memset"]
}

• to ban my_printf (because you dont want to use it)

{
    "banned": ["my_printf"]
}

• to no-banne *.o file (because you dont need this warning)

{
    "no-extension": ["*.o"]
}

• to banne *.c file (because you want c file banned)

{
    "extension": ["*.c"]
}

• to enable preview check by default

{
    "enable-preview": true
}

by default there are somthing like this:

{
    "banned": ["printf", "memset", "strcpy", "strcat", "calloc"],
    "no-banned": [],
    "extension": ["*.a", "*.o", "*.so", ".gch", "*~", "*#", "*.d"],
    "no-extension": [],
    "enable-preview": false
}

this configuration will be added even if you add a .normatrix.json file

but if you want to remove *.o, just add it to the no-extension

or you can put *.o in a .gitignore

it will remove it from the default

Run as a github workflow

this is not the latest normatrix but :

link : link

state :

(N.B. : this workflow pass well, but it will not if you copy the code below)

1. in the repo root :

mkdir .github
mkdir .github/workflows
echo '
name: NorMatrix Check

on: [push]

jobs:
  norm:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v2

    - name: set up python
      uses: actions/setup-python@v2
      with:
        python-version: '3.9'

    - name: clone NorMatrix
      run: pip install git+https://github.com/Saverio976/NorMatrix.git

    - name: NorMatrix
      run: python3 -m normatrix --only-errors
' > .github/workflows/normatrix_check.yml

2. you can push the modification to github
