It +is a guide for how and why to use each feature or mechanism of OpenOCD. +It is also the reference manual for all commands and options involved +in using them, including interface, flash, target, and other drivers. +At this time, it is the only user-targetted documentation; everything +else is addressing OpenOCD developers. + +There are two key audiences for the User's Guide, both developer based. +The primary audience is developers using OpenOCD as a tool in their +work, or who may be starting to use it that way. A secondary audience +includes developers who are supporting those users by packaging or +customizing it for their hardware, installing it as part of some software +distribution, or by evolving OpenOCD itself. There is some crossover +between those audiences. We encourage contributions from users as the +fundamental way to evolve and improve OpenOCD. In particular, creating +a board or target specific configuration file is something that many +users will end up doing at some point, and we like to see such files +become part of the mainline release. + +General documentation rules to remember include: + +- Be concise and clear. It's work to remove those extra words and + sentences, but such "noise" doesn't help readers. +- Make it easy to skim and browse. "Tell what you're going to say, + then say it". Help readers decide whether to dig in now, or + leave it for later. +- Make sure the chapters flow well. Presentations should not jump + around, and should move easily from overview down to details. +- Avoid using the passive voice. +- Address the reader to clarify roles ("your config file", "the board you + are debugging", etc.); "the user" (etc) is artificial. +- Use good English grammar and spelling. Remember also that English + will not be the first language for many readers. Avoid complex or + idiomatic usage that could create needless barriers. +- Use examples to highlight fundamental ideas and common idioms. +- Don't overuse list constructs. This is not a slide presentation; + prefer paragraphs. + +When presenting features and mechanisms of OpenOCD: + +- Explain key concepts before presenting commands using them. +- Tie examples to common developer tasks. +- When giving instructions, you can \...@enumerate each step both + to clearly delineate the steps, and to highlight that this is + not explanatory text. +- When you provide "how to use it" advice or tutorials, keep it + in separate sections from the reference material. +- Good indexing is something of a black art. Use \...@cindex for important + concepts, but don't overuse it. In particular, rely on the \...@deffn + indexing, and use \...@cindex primarily with significant blocks of text + such as \...@subsection. The \...@dfn of a key term may merit indexing. +- Use \...@xref (and \...@anchor) with care. Hardcopy versions, from the PDF, + must make sense without clickable links (which don't work all that well + with Texinfo in any case). If you find you're using many links, + read that as a symptom that the presentation may be disjointed and + confusing. +- Avoid font tricks like \...@b, but use \...@option, \...@file, \...@dfn, \...@emph + and related mechanisms where appropriate. + +For technical reference material: + +- It's OK to start sections with explanations and end them with + detailed lists of the relevant commands. +- Use the \...@deffn style declarations to define all commands and drivers. + These will automatically appear in the relevant index, and those + declarations help promote consistent presentation and style. + - It's a "Command" if it can be used interactively. + - Else it's a "Config Command" if it must be used before the + configuration stage completes. + - For a "Driver", list its name. + - Use BNF style regular expressions to define parameters: + brackets around zero-or-one choices, parentheses around + exactly-one choices. + - Use \...@option, \...@file, \...@var and other mechanisms where appropriate. + - Say what output it displays, and what value it returns to callers. + - Explain clearly what the command does. Sometimes you will find + that it can't be explained clearly. That usually means the command + is poorly designed; replace it with something better, if you can. + - Be complete: document all commands, except as part of a strategy + to phase something in or out. + - Be correct: review the documentation against the code, and + vice versa. +- Alphabetize the \...@defn declarations for all commands in each + section. +- Keep the per-command documentation focussed on exactly what that + command does, not motivation, advice, suggestions, or big examples. + When commands deserve such expanded text, it belongs elsewhere. + Solutions might be using a \...@section explaining a cluster of related + commands, or acting as a mini-tutorial. +- Details for any given driver should be grouped together. + +The User's Guide is the first place most users will start reading, +after they begin using OpenOCD. Make that investment of their time +be as productive as possible. Needing to look at OpenOCD source code, +to figure out how to use it is a bad sign, though it's OK to need to +look at the User's guide to figure out what a config script is doing. */ /** @page stylelatex LaTeX Style Guide
