+# Contributing
+
+Contributions to `@sasjs/lint` are very welcome!
+Please fill in the pull request template and make sure that your code changes are adequately covered with tests when making a PR.
+
+## Architecture
+
+This project implements a number of rules for SAS projects and code. There are three types of rules:
+
+* File rules - rules applied at the file level
+* Line rules - rules applied to each line of a file 
+* Path rules - rules applied to paths and file names
+
+When implementing a new rule, place it in the appropriate folder for its type.
+Please also make sure to export it from the `index.ts` file in that folder.
+
+The file for each rule typically exports an object that conforms to the `LintRule` interface.
+This means it will have a `type`, `name`, `description` and `message` at a minimum.
+
+File, line and path lint rules also have a `test` property.
+This is a function that will run a piece of logic against the supplied item and produce an array of `Diagnostic` objects.
+These objects can be used in the consuming application to display the problems in the code.
+
+With some lint rules, we can also write logic that can automatically fix the issues found.
+These rules will also have a `fix` property, which is a function that takes the original content -
+either a line or the entire contents of a file, and returns the transformed content with the fix applied.
+
+## Testing
+
+Testing is one of the most important steps when developing a new lint rule.
+It helps us ensure that our lint rules do what they are intended to do.
+
+We use `jest` for testing, and since most of the code is based on pure functions, there is little mocking to do.
+This makes `@sasjs/lint` very easy to unit test, and so there is no excuse for not testing a new rule. :)
+
+When adding a new rule, please make sure that all positive and negative scenarios are tested in separate test cases.
+When modifying an existing rule, ensure that your changes haven't affected existing functionality by running the tests on your machine.
+
+You can run the tests using `npm test`.
+
+## Code Style
+
+This repository uses `Prettier` to ensure a uniform code style.
+If you are using VS Code for development, you can automatically fix your code to match the style as follows:
+
+- Install the `Prettier` extension for VS Code.
+- Open your `settings.json` file by choosing 'Preferences: Open Settings (JSON)' from the command palette.
+- Add the following items to the JSON.
+  ```
+    "editor.formatOnSave": true,
+    "editor.formatOnPaste": true,
+  ```
+
+If you are using another editor, or are unable to install the extension, you can run `npm run lint:fix` to fix the formatting after you've made your changes.

 # SAS Code linting and formatting

 Our goal is to help SAS developers everywhere spend less time on code reviews, bug fixing and arguing about standards - and more time delivering extraordinary business value.

-## Linting
+# Linting
+
@sasjs/lint is used by the following products:

-  * [@sasjs/vscode-extension](https://github.com/sasjs/vscode-extension) - just download SASjs in the VSCode marketplace, and select view/problems in the menu bar.
-  * [@sasjs/cli](https://cli.sasjs.io/lint) - run `sasjs lint` to get a list of all files with their problems, along with line and column indexes.

+- [@sasjs/cli](https://cli.sasjs.io/lint) - run `sasjs lint` to get a list of all files with their problems, along with line and column indexes.

 Configuration is via a `.sasjslint` file with the following structure (these are also the defaults if no .sasjslint file is found):

 ```json
 {
-    "noEncodedPasswords": true,
-    "hasDoxygenHeader": true,
-    "hasMacroNameInMend": true,
-    "hasMacroParentheses": true,
-    "indentationMultiple": 2,
-    "lowerCaseFileNames": true,
-    "maxLineLength": 80,
-    "noNestedMacros": true,
-    "noSpacesInFileNames": true,
-    "noTabIndentation": true,
-    "noTrailingSpaces": true
+  "noEncodedPasswords": true,
+  "hasDoxygenHeader": true,
+  "hasMacroNameInMend": true,

+  "noTrailingSpaces": true,
+  "defaultHeader": "/**{lineEnding}  @file{lineEnding}  @brief <Your brief here>{lineEnding}  <h4> SAS Macros </h4>{lineEnding}**/"
 }
 ```

-### SAS Lint Settings
+## SAS Lint Settings

-#### noEncodedPasswords
+Each setting can have three states:

-This will highlight any rows that contain a `{sas00X}` type password, or `{sasenc}`.  These passwords (especially 001 and 002) are NOT secure, and should NEVER be pushed to source control or saved to the filesystem without special permissions applied.
+- OFF - usually by setting the value to `false` or 0. In this case, the rule won't be executed.
+- WARN - a warning is written to the log, but the return code will be 0
+- ERROR - an error is written to the log, and the return code is 1

-* Default:  true
-* Severity: ERROR
+For more details, and the default state, see the description of each rule below. It is also possible to change whether a rule returns ERROR or WARN using the `severityLevels` object.

-#### hasDoxygenHeader
-The SASjs framework recommends the use of Doxygen headers for describing all types of SAS program.  This check will identify files where a doxygen header does not begin in the first line.
+### defaultHeader

-* Default:  true
-* Severity: WARNING
+This isn't actually a rule - but rather a formatting setting, which applies to SAS program that do NOT begin with `/**`. It can be triggered by running `sasjs lint fix` in the SASjs CLI, or by hitting "save" when using the SASjs VS Code extension (with "formatOnSave" in place)

-#### hasMacroNameInMend
-The addition of the macro name in the `%mend` statement is optional, but can approve readability in large programs.  A discussion on this topic can be found [here](https://www.linkedin.com/posts/allanbowe_sas-sasapps-sasjs-activity-6783413360781266945-1-7m).  The default setting will be the result of a popular vote by around 300 people.
+The default header is as follows:

-* Default:  true
-* Severity: WARNING
+```sas
+/**
+  @file
+  @brief <Your brief here>
+  <h4> SAS Macros </h4>
+**/
+```

-#### hasMacroParentheses
-As per the example [here](https://github.com/sasjs/lint/issues/20), macros defined without parentheses cause problems if that macro is ever extended (it's not possible to reliably extend that macro without potentially breaking some code that has used the macro).  It's better to always define parentheses, even if they are not used.  This check will also throw a warning if there are spaces between the macro name and the opening parenthesis.
+If creating a new value, use `{lineEnding}` instead of `\n`, eg as follows:

-* Default:  true
-* Severity: WARNING
+```json
+{
+  "defaultHeader": "/**{lineEnding}  @file{lineEnding}  @brief Our Company Brief{lineEnding}**/"
+}
+```
+
+### noEncodedPasswords

+
+- Default: true
+- Severity: WARNING
+
+### ignoreList
+
+There may be specific files (or folders) that are not good candidates for linting. Simply list them in this array and they will be ignored. In addition, any files in the project `.gitignore` file will also be ignored.
+
+### indentationMultiple

-#### indentationMultiple
 This will check each line to ensure that the count of leading spaces can be divided cleanly by this multiple.

-* Default:  2
-* Severity: WARNING
+- Default: 2
+- Severity: WARNING

-#### lowerCaseFileNames
-On *nix systems, it is imperative that autocall macros are in lowercase.  When sharing code between windows and *nix systems, the difference in case sensitivity can also be a cause of lost developer time.  For this reason, we recommend that sas filenames are always lowercase.

-#### maxLineLength
-Code becomes far more readable when line lengths are short.  The most compelling reason for short line lengths is to avoid the need to scroll when performing a side-by-side 'compare' between two files (eg as part of a GIT feature branch review).  A longer discussion on optimal code line length can be found [here](https://stackoverflow.com/questions/578059/studies-on-optimal-code-width)
+- Default: true
+- Severity: WARNING

-In batch mode, long SAS code lines may also be truncated, causing hard-to-detect errors.  
+### maxLineLength

-For this reason we strongly recommend a line length limit, and we set the bar at 80.  To turn this feature off, set the value to 0.

-#### noNestedMacros
-Where macros are defined inside other macros, they are recompiled every time the outer maro is invoked.  Hence, it is widely considered inefficient, and bad practice, to nest macro definitions.

+### noGremlins
+
+Capture zero-width whitespace and other non-standard characters.  The logic is borrowed from the [VSCode Gremlins Extension](https://github.com/nhoizey/vscode-gremlins) - if you are looking for more advanced gremlin zapping capabilities, we highly recommend to use their extension instead.

-#### noSpacesInFileNames
 The 'beef' we have with spaces in filenames is twofold:

-* Loss of the in-built ability to 'click' a filepath and have the file open automatically
-* The need to quote such filepaths in order to use them in CLI commands
+- Loss of the in-built ability to 'click' a filepath and have the file open automatically

-In addition, when such files are used in URLs, they are often padded with a messy "%20" type quotation.  And of course, for macros (where the macro should match the filename) then spaces are simply not valid.

-* `noTabs` -> does what it says on the tin 
-* `noGremlins` -> identifies all invisible characters, other than spaces / tabs / line endings.  If you really need that bell character, use a hex literal!
-* `lineEndings` -> set a standard line ending, such as LF or CRLF
+- Default: true
+- severity: WARNING

-## SAS Formatter
+## severityLevel
+
+This setting allows the default severity to be adjusted. This is helpful when running the lint in a pipeline or git hook. Simply list the rules you would like to adjust along with the desired setting ("warn" or "error"), eg as follows:
+
+```json
+{
+  "noTrailingSpaces": true,
+  "hasDoxygenHeader": true,
+  "maxLineLength": 100,
+  "severityLevel": {
+    "hasDoxygenHeader": "warn",
+    "maxLineLength": "error",
+    "noTrailingSpaces": "error"
+  }
+}
+```
+
+- "warn" - show warning in the log (doesn’t affect exit code)
+- "error" - show error in the log (exit code is 1 when triggered)
+
+## Upcoming Linting Rules:
+
+- `noGremlins` -> identifies all invisible characters, other than spaces / tabs / line endings. If you really need that bell character, use a hex literal!
+- `lineEndings` -> set a standard line ending, such as LF or CRLF
+
+# SAS Formatter

 A formatter will automatically apply rules when you hit SAVE, which can save a LOT of time.

+We've already implemented the following rules:
+
+- Add the macro name to the %mend statement
+- Add a doxygen header template if none exists
+- Remove trailing spaces
+
 We're looking to implement the following rules:

-* Remove trailing spaces
-* Change tabs to spaces 
-* Add the macro name to the %mend statement 
-* Add a doxygen header template if none exists 
+- Change tabs to spaces
+- zap gremlins
+- fix line endings

-Later we will investigate some harder stuff, such as automatic indentation and code layout

-## SAS 9 Health check
+# Contributors ✨

-The SASjs Linter (and formatter) is a great way to de-risk and accelerate the delivery of SAS code into production environments.  However, code is just one part of a SAS estate.  If you are running SAS 9, you may be interested to know what 'gremlins' are lurking in your system.  Maybe you are preparing for a migration.  Maybe you are preparing to hand over the control of your environment.  Either way, an assessment of your existing system would put minds at rest and pro-actively identify trouble spots.
+<!-- ALL-CONTRIBUTORS-BADGE:START - Do not remove or modify this section -->

-The SAS 9 Health Check is a 'plug & play' product, that uses the [SAS 9 REST API](https://sas9api.io) to run hundreds of metadata and system checks to identify common problems.  The checks are non-invasive, and becuase it is a client app, there is NOTHING TO INSTALL on your SAS server.  We offer this assessment for a low fixed fee, and if you engage our (competitively priced) services to address the issues we highlight, then the assessment is free.
