feat(installer): implement "installer" Squashed commit of the following: commit 5c322e79b7b6fa6bef51cac2f9b03fe2eaf08163 Author: Chris Lane <chris@chris-allen-lane.com> Date: Fri Mar 6 19:56:56 2020 -0500 docs(README): update the `README` Update the `README` to document the improved config-generation mechanism. commit 803e1f014cc89c30bfb80549b64195235b8b9f62 Author: Chris Lane <chris@chris-allen-lane.com> Date: Fri Mar 6 19:19:49 2020 -0500 feat(config-init): platform-specific pathing Update `--init` subcommand to rely upon the same platform-detection intelligence that was previously implemented by the "installer". The installer and `--init` should now produce identical config files. commit 99c48097e2e23755710d08a099918675895192f7 Author: Chris Lane <chris@chris-allen-lane.com> Date: Fri Mar 6 18:26:33 2020 -0500 feat(installer): platform-correct config templating Modify the "installer" to populate cheatpaths with sensible defaults based on the detection of the user's operating system and environment. commit 8e1580ff5a30ae3241c3f02b806666583c5d44b2 Author: Chris Lane <chris@chris-allen-lane.com> Date: Thu Mar 5 20:19:58 2020 -0500 fix(tests): fix `config.Paths` tests Refactor `config.Paths` (by externalizing a call to `homedir.Dir`) to decouple it from filesystem paths, thus facilitating cleaner unit-tests. commit a08dca70d90bb6d568d44abf76b2bd911d929001 Author: Chris Lane <chris@chris-allen-lane.com> Date: Thu Mar 5 18:14:27 2020 -0500 feat(installer): default path selection Modify the installer to improve default config and cheatsheet path selection. commit e15bc6c966bfdca3b507504c95a34b74e264be11 Author: Chris Lane <chris@chris-allen-lane.com> Date: Thu Mar 5 17:49:50 2020 -0500 fix(typo): correct comment typo in `main.go` commit efd09575df4422449d6178cd922a680e0f871c21 Author: Chris Lane <chris@chris-allen-lane.com> Date: Thu Mar 5 17:46:49 2020 -0500 feat(config): refactor config path detection Previously, failing other checks, on Unix and BSD systems, `config.Paths` would attempt to compute the user's home directory by reading the `HOME` environment variable. This change deprecates that approach with a call to `homedir.Dir`, which is used elsewhere throughout the application. commit ec10244ebeb2a48e5c694aeabb8bcbc177a77369 Author: Chris Lane <chris@chris-allen-lane.com> Date: Thu Mar 5 17:15:28 2020 -0500 chore(installer): delete unused file Delete `installer/installer.go`, which (in hindsight) was unnecessary. commit ebd9ec62873d7f286586ea0af9113d74b8a1d2f2 Author: Chris Lane <chris@chris-allen-lane.com> Date: Wed Mar 4 19:31:13 2020 -0500 wip(installer): stub experimental "installer" Stubs out an experimental "installer" that will help new users to quickly configure `cheat`. commit ecac5a09717a4a4714637946d3699da5db97fcc7 Author: Chris Lane <chris@chris-allen-lane.com> Date: Wed Mar 4 19:30:12 2020 -0500 chore(dependencies): updates vendored dependencies
