Coding-style checker for Epitech students. This program analyzes your C and Haskell source files for [Epitech C coding-style] and [Epitech Haskell coding-style] violations.

*[French] Moulinette de norme pour les étudiants d'Epitech. Cette norminette cherche des erreurs de [norme C Epitech][Epitech C coding-style] et de [norme Haskell Epitech][Epitech Haskell coding-style] dans vos fichers de code source C et Haskell.*

## Getting started

### Requirements

- [Ruby](https://www.ruby-lang.org/en/)

#### Installing Ruby on Fedora (Epitech's 2017 dump)

```sh
sudo dnf install ruby
```

### How to use NormEZ?

1. Clone the repository:
```sh
git clone https://github.com/ronanboiteau/NormEZ
```
2. Run `make install` to install NormEZ or `make uninstall` to uninstall it
3. Run NormEZ:
```sh
normez
```
4. NormEZ will recursively search for `.c` and `.h` files to analyze in your current directory.
5. You can also pass specific files to check as argument:
```sh
normez src/*.c src/*.h
```

## Options

- `-u` or `--no-update`: don't check for NormEZ updates
- `-f` or `--ignore-files`: ignore forbidden files
- `-m` or `--ignore-functions`: ignore forbidden functions
- `-i` or `--ignore-all`: ignore forbidden files & forbidden functions (same as `-fm`)
- `-c` or `--colorless`: disable all styling on output

## Features

Coding-style violations checked by NormEZ.

Major infraction = major infraction

Minor infraction = minor infraction

### C

Major infraction Lines with too many columns (> 80).

Major infraction Forbidden files: every regular file that does not match `Makefile`, `*.c` or `*.h` (ex: `*.o`, `*.gch`, `bsq`, ...) & that is not mentioned in a [`.gitignore`](https://git-scm.com/docs/gitignore) file located in your current working directory.

Major infraction *[Not exhaustive]* Too broad filenames (ex: `string.c`, `algo.c`, `my_algorithm.c`, ...).

Major infraction Missing or corrupted header in sources files (`.c`), headers (`.h`) & `Makefile`s.

Major infraction Functions that contain more than 20 lines.

Major infraction Several semicolon-separated assignments on the same line.

Major infraction *[Not exhaustive]* Forbidden functions (`printf()`, `dprintf()`, `atoi()`, `memcpy()`, `scanf()`, `strlen()`...).

Major infraction Trailing space(s) and/or tabulation(s) at the end of a line.

Major infraction Filenames that don't respect the [snake_case] naming convention.

Major infraction Condition and assignment on the same line.

Major infraction Directory names that don't respect the [snake_case] naming convention.

Major infraction Too many functions in file (> 5).

Major infraction Functions with no parameters that don't take void as argument in their declaration.

Major infraction Functions with too many arguments (> 4).

Minor infraction Space(s) in indentation.

Minor infraction Missing space after keyword.

Minor infraction Misplaced pointer symbol(s).

Minor infraction Macros used for constants.

Minor infraction Macros containing multiple assignments.

Minor infraction Too many `else if` statements.

Minor infraction Misplaced comments.

Minor infraction Missing space after comma.

Minor infraction Missing space around binary or ternary operator (`=`, `==`, `!=`, `<=`, `>=`, `&&`, `||`, `+=`, `-=`, `*=`, `/=`, `%=`, `&=`, `^=`, `|=`, `|`, `^`, `>>`, `<<`, `>>=`, `<<=`).

Minor infraction Extra space after unary operators (`!`, `sizeof`, `++`, `--`).

Minor infraction Forbidden keyword (`goto`).

Minor infraction Functions must be separated by *one and only one* empty line in `.c` files.

### Haskell

Major infraction Lines with too many columns (> 80).

Major infraction Functions that contain more than 10 lines.

Major infraction Filenames that don't respect the [UpperCamelCase](https://en.wikipedia.org/wiki/Camel_case) naming convention.

Major infraction Imbedded `if` blocks.

Major infraction Mutable variables used.

Major infraction Missing type signatures.

Major infraction Useless `do`.

Minor infraction *[Not exhaustive]* Guards that should be pattern matching.

## To-do

Coding-style violations ***NOT YET*** checked by NormEZ.

Major infraction = major infraction

Minor infraction = minor infraction

### C

Major infraction Typedef not ending with `_t`.

Major infraction Identifiers that don't respect the [snake_case] naming convention.

Major infraction Macros, global constants or enums that don't respect the SNAKE_CASE convention (uppercase [snake_case]).

Major infraction Function prototypes, typedefs, global variables, macros or static inline functions in `.c` source files.

Minor infraction Single-letter identifiers shouldn't be named `l` (lowercase `L`) or `o` to avoid confusions.
Minor infraction Nested conditonal branchings (depth > 2).

Minor infraction Header files not protected against double inclusion

Minor infraction Wrong indentation level in `.c` and `.h` files.

Minor infraction Wrong indentation level in pre-processor directives.

Minor infraction Extra space between function name and opening parenthesis.

Minor infraction Misplaced curly brackets.

Minor infraction Multiple variables declared on the same line.

Minor infraction Variable not declared at the beginning of function.

Minor infraction Missing empty line after variable declarations.

Minor infraction Extra empty lines in function.

### Haskell

Major infraction Naming identifiers according to the [lowerCamelCase](https://en.wikipedia.org/wiki/Camel_case) convention.

Major infraction Forbidden language extentions.

Major infraction Contents of delivery folder

## Bugs

### Known issues

- NormEZ doesn't make the difference between strings/comments & code. Examples: a commented forbidden function will be flagged, as well as a commented `;` (multiple assignments on the same line), etc.
- The check for functions containing more than 20 lines doesn't work yet with the new coding style v3.1. [See related issue.](https://github.com/ronanboiteau/NormEZ/issues/20)
- For Haskell, the check of guards that should be expressed as pattern matching is not very accurate, it flags guards that use only direct comparisons (or `==`)
