Projectionist provides granular project configuration using "projections".  What are projections?  Let's start with an example. ## Example A while back I went and made a bunch of plugins for working with rbenv.  Here's what a couple of them look like:     ~/.rbenv/plugins $ tree     .     |-- rbenv-ctags     |   |-- bin     |   |   `-- rbenv-ctags     |   `-- etc     |       `-- rbenv.d     |           `-- install     |               `-- ctags.bash     `-- rbenv-sentience         `-- etc             `-- rbenv.d                 `-- install                     `-- sentience.bash As you can see, rbenv plugins have hooks in `etc/rbenv.d/` and commands in `bin/` matching `rbenv-*`.  Here's a projectionist configuration for that setup:     let g:projectionist_heuristics = {           \   "etc/rbenv.d/|bin/rbenv-*": {           \     "bin/rbenv-*": {           \        "type": "command",           \        "template": ["#!/usr/bin/env bash"],           \     },           \     "etc/rbenv.d/*.bash": {"type": "hook"}           \   }           \ } The key in the outermost dictionary says to activate for any directory containing a subdirectory `etc/rbenv.d/` *or* files matching `bin/rbenv-*`.  The corresponding value contains projection definitions.  Here, two projections are defined.  The first creates an `:Ecommand` navigation command and provides boilerplate to pre-populate new files with, and the second creates an `:Ehook` command. ## Features See `:help projectionist` for the authoritative documentation.  Here are some highlights. ### Global and per project projection definitions In the above example, we used the global `g:projectionist_heuristics` to declare projections based on requirements in the root directory.  If that's not flexible enough, you can use the autocommand based API, or create a `.projections.json` in the root of the project. ### Navigation commands Navigation commands encapsulate editing filenames matching certain patterns.  Here are some examples for this very project:     {       "plugin/*.vim": {"type": "plugin"},       "autoload/*.vim": {"type": "autoload"},       "doc/*.txt": {"type": "doc"},       "README.markdown": {"type": "doc"}     } With these in place, you could use `:Eplugin projectionist` to edit `plugin/projectionist.vim` and `:Edoc projectionist` to edit `doc/projectionist.txt`.  For `README.markdown`, since there's no glob, it becomes the default destination for `:Edoc` if no argument is given. The `E` stands for `edit`.  You also get `S`, `V`, and `T` variants that `split`, `vsplit`, and `tabedit`. Tab complete is smart.  Not quite "fuzzy finder" smart but smart nonetheless.  (On that note, fuzzy finders are great, but I prefer the navigation command approach when there are multiple categories of similarly named files.) ### Alternate files Projectionist provides `:A`, `:AS`, `:AV`, and `:AT` to jump to an "alternate" file, based on ye olde convention originally established in vimscript #31.  Here's an example configuration for Maven that allows you to jump between the implementation and test:     {       "src/main/java/*.java": {"alternate": "src/test/java/{}.java"},       "src/test/java/*.java": {"alternate": "src/main/java/{}.java"}     } Bonus feature: `:A {filename}` edits a file relative to the root of the project. ### Buffer configuration Check out these examples for a minimal Ruby project:     {       "*": {"make": "rake"},       "spec/*_spec.rb": {"dispatch": "rspec {file}"}     } That second one sets the default for dispatch.vim (vimscript #4504).  Plugins can use projections for their own configuration.
