We will +describe some common use-cases and showcase how the package is +used. + +The package is currently not yet published in a package archive, +but the code is already publicly available at +<https://github.com/hokomo/query-replace-parallel>. The name +"query-replace-parallel" is not yet final and we are thinking of +alternatives.

I failed miserably in that, but I became fascinated by +languages, and I discovered Forth - that was perfect for writing +languages whose syntax was as simple as possible. Then I switched to +GNU/Linux and I had a series of favorite languages; at some point I +discovered Lua, that became not only my favorite language but also my +favorite tool for implementing other languages. One of the main +libraries of Lua is something called LPeg, that lets "people" +implement complex parsers in just a few lines of code using PEGs - +Parsing Expression Grammars. + +I've put the "people" in the last paragraph between quotes because for +many years I wasn't included in the "people who can implement complex +parsers with LPeg"… lots of things in LPeg didn't make sense to me, +and I couldn't visualize how it worked. Something was missing - some +diagrams, maybe? + +The main tool for drawing diagrams in LaTeX is something called TikZ, +that is HUGE - its manual has over 1000 pages. TikZ includes lots of +libraries and extensions, and each one of these libraries and +extensions extends TikZ's core language with some extra constructs. + +I don't know anyone - except for a handful of experts - who knows what +is the "core language" of Tikz, that lies, or that should lie, below +all these extensions… all of my friends who use TikZ are just +"users" of TikZ - they've learned some parts of TikZ by starting with +exemples, and by then modifying these examples mostly by trial and +error. In particular, no one among my friends knows how styles in TikZ +really work; styles are implemented using "keys", that are hard to +inspect from a running TeX - see [1] - and I found the chapter on "key +management" in the manual very hard to understand. It feels as if +something is missing from it… some diagrams, maybe? + +In my day job I am a mathematician. I work in a federal university in +Brazil, and besides teaching I do some research - mostly in areas in +which the papers and theses have lots of diagrams, of many different +kinds, and in which people use zillions of different programs to draw +their diagrams. Every time that I see those diagrams I think "wow, I +<span class="underline">need</span> to learn how to draw diagrams like that!", but until a few +months ago this seemed to be impossible, or very hard, or very +painful… + +This presentation will be about a point in which all these ideas +intersect. I am the author of an Emacs package called eev, that +encourages using REPLs in a certain way; Lua can be used in several +different styles, and if we use it in a certain way that most people +hate - with lots of globals, and with an implementation of OO that +makes everything inspectable and modifiable - then it becomes very +REPL-friendly; there is an extension of LPeg called LPegRex ([2], +[3]), that I found promising but hard to use, so I rewrote some parts +of it to make them more REPL-friendly, and to make it print its ASTs +in 2D ASCII art. The core of my presentation will be about how I am +using REPLs written in Lua to write grammars, parsers, and tools to +generate many kinds of diagrams, and how I am using these diagrams to +document both my own code and other people's programs - the parts of +them in which some diagrams seem to be missing. My hope is that people +will find these ideas easy to port to other languages besides Lua, to +other tools for generating diagrams besides LaTeX - SVG, maybe? - and +to other ways to use REPLs in Emacs besides eev.
