Navigating the Labyrinth of Coding Guidelines: Origins, Impacts, and Best Practices
0:00:03 - Introduction to Coding Guidelines: The talk focuses on the use of coding guidelines in projects, beyond just mentioning the C++ Core Guidelines.
0:00:17 - Speaker Introduction: Arna, with over 9 years of experience at Tu and 20+ years in C++, shares insights from 12 projects, including embedded systems.
0:01:11 - Prevalence of Style Guides: Coding style guides are common in nearly every project, whether provided by the customer or created by the development team.
0:02:22 - Jack of All Trades Proverb: The talk begins with the proverb "Jack of all trades, master of none," discussing the original meaning where a generalist is often more useful than a specialist.
0:02:51 - The Importance of Generalists: Projects often require both specialists and generalists, especially in small teams where individuals need to handle multiple responsibilities beyond just coding.
0:05:05 - Rule of Five Discussion: The guideline "Define or delete all copy, move, and destruct functions" is discussed. This comes from C.21 in the C++ Core Guidelines which itself supports a related rule of zero and encourages defining all or none of the special functions.
0:07:17 - Potential Issues of the "Always Define" Guideline: Following the rule of five without careful thought can lead to needless boilerplate code, encourage code deletion, and cause problems with resource management, potentially leading to increased memory allocations.
0:09:15 - Guidelines vs. Rules: Guidelines should not be interpreted as strict rules, as there are often exceptions and a need for thoughtful consideration.
0:10:25 - Guidelines with Exceptions: Guidelines are less strict, allowing for exceptions if developers have thought through the implications.
0:10:25 - Rule of Zero & Five: An exception can occur in "interfaces to only define a defaulted virtual destructor and not touch everything else," in contrast to a specific "Rule."
0:10:25 - Automated Tooling: With static analysis, the guideline turns to a "Rule" to make code more consistent, easier to understand.
0:13:50 - "Don't use exceptions" guideline: This comes from the Google Style Guide.
0:14:23 - Google's Reasoning Against Exceptions: Google avoids exceptions due to the complexity of introducing them into their vast existing codebase.
0:15:00 - Google Use Case: Certain projects at Google do use exceptions where dependencies are less critical, emphasizing the importance of context.
0:15:33 - Potential Issues with Avoidance: Avoiding exceptions can complicate error handling, requiring the use of return codes, output parameters, and making testing more tedious.
0:17:31 - Universality of Guidelines: Not all guidelines are universal and portable.
0:17:31 - Checking Guidelines: Double-check where your guidelines come from to determine if they apply to the current team/project.
0:18:42 - "Every function shall have a single return statement": This is an extreme case, based on functional safety needs (MISRA C standard).
0:19:26 - Counterarguments Against Single Exit Points: Early returns using guard clauses can improve readability and using RAII eliminates the need for manual resource management at the end of a function.
0:22:22 - What is SE/SEE?: "Single Exit/Entry". SE/SEE comes from never jumping into alternative entry points or different exit points.
0:23:00 - Origins of SE/SEE: Code design from the 1960s/1970s with Edgar Dyjstra and assembler.
0:23:56 - Impact of Single Exit Point: Forced single exit returns reduce code quality.
0:23:56 - No Exceptions: Cannot use Exceptions because an exception call creates an implicit return, violating guideline.
0:26:02 - Know Where the Guidelines Come From: Know where the guidelines come from.
0:26:02 - RAII: Please use RAII to handle resource responsibility management.
0:28:02 - "Don't Use References as Members": This is from C++ Core Guidelines C.12.
0:28:14 - Context of the rule: Only applies to types that need copyability and moveability.
0:29:43 - Quote Randomizer Service (Example): A quote randomizer service doesn't need copyability so don't enforce this guideline.
0:30:52 - Invariant Types: Doesn't matter to have a copy or move constructor or assignment if there is no need.
0:30:52 - Reasons for Guideline Matters: In the core guideline document usually is a title, elaboration, and four paragraphs of rationale.
0:32:37 - "Constitency": Don't ignore the rule of zero or other guidelines if this one is okay, and make sure the codebase is consistent.
0:32:57 - Don't be Dogmatic: Don't just say "OK, the guideline says this, I have to do this everywhere."
0:32:57 - References: The code reviewer may not fully know why certain references were used in a certain place.
0:33:00 - Use References: Use references in the design of "graphs of dependencies" and where code is immutable.
0:33:34 - Const goes on the left of the type (West Const)": NL.26 recommends conventional notation.
0:33:45 - Emphasis on Consistency: The most important aspect is consistency within the code base, regardless of whether East or West const is used.
0:35:05 - Naming and Layout "Suggestions": The Naming section "Suggestions" from Core Guidelines are not guidelines or rules.
0:35:35 - Tooling: Clang-format can take care of formatting.
0:36:06 - Formatting: Don't use guidelines about how to format the code, because this is a tooling thing.
0:36:37 - "Tooling to Format": Please don't make me read formatting rules, just provide the tooling to format code.
0:37:24 - "Use Singletons for Objects that Exist Only Once": Use Singletons: oh boy, this has resulted in many discussions.
0:37:42 - Intent from Gang of Four: "Ensure that a class has only one instance and provide a global point of exis."
0:37:54 - Reason for Guidelines: The original reasoning from the early 1990s from "gang of four" is that a global variable makes an object accessible but doesn't stop the object being instantiated several times.
0:38:10 - Modern Guidelines: If you need the singleton to apply to everyone, than use a Singleton.
0:38:47 - Long Discussion: "What discussions? we had a 4-5ish million line of code base."
0:39:17 - Problems: Touched a class then it was touched by the Singleton.
0:39:52 - Text Needs Interpreting: A pattern should be interpreted and needs to be understood by everyone.
0:40:10 - The Modern C++ Case: In modern C++, an "Edit Function" has taken Singleton's place.
0:40:57 - Logging (Example): Use a Stitchy out Stitchy for the Logging.
0:41:20 - No Reason for Singlton's: No reason to use 100s of Singletons.
0:42:15 - Guidelines for your Team: These are "guidelines for guidelines."
0:42:21 - Context and Rational: Understand the context and the rational of adopting guidelines.
0:42:21 - Broken Guidelines: Guidelines can and may be broken.
0:42:40 - Name Conventions: Use name conventions so it is easier to distinguish areas where the guidelines apply.
0:43:00 - Code You Can't Automate: Concentrate on writing guidelines down you can't automate.
0:43:40 - Developer Tools: Developers love automated tools because they tell us what to do (sort of).
0:43:40 - Always Easy?: Developers want the tools to be warning free because if not, it's just easy to ignore the warnings.
0:44:21 - Tooling Freedom: However guidelines means freedom which means responsibilities, so don't turn off your brains.
0:45:53 - Responsibility to Check: Need to play metrics by saying tools tell you what to do.
0:46:48 - Make it Correct: Don't violate the code, make it correct.
0:47:18 - Documents for Code: Make sure all developers are aware of the documents when code is written.
0:47:24 - Guideline Document Style: Should be short and accessible.
0:48:18 - Team Landscape: To determine the team landscape.
0:49:44 - Experience: A great way to learn and adopt a document with new or younger members.
**0:50:01 - Trust & Agreements: What the document means and what to do with it, but most importantly what to use.
0:50:20 - Customer Guidelines: These opinions should be in one place where everyone can access them.
0:51:33 - Weekly Meetings and Discussions: When people come to meetings and say we should have a discussion about a certain topic.
0:51:45 - Challenger Guidelines: There are some customers who challenge the guidelines and make recommendations.
0:52:37 - Challenging: Customers are always right in matters of taste, not so with challenges.
0:53:14 - C vs C++: A lot of times, the code challenges a customer.
0:53:40 - Always Changing: Most importantly, make sure that all these documents are accessible and changing with the team.
