Reform Parser (#509) Just's first parser performed both parsing, i.e the transformation of a token stream according to the language grammar, and a number of consistency checks and analysis passes. This made parsing and analysis quite complex, so this diff introduces a new, much cleaner `Parser`, and moves existing analysis into a dedicated `Analyzer`. 2019-11-07 10:55:15 -08:00			`use crate::common::*;`

Resolve alias targets (#548) During analysis, resolve alias targets from `Name`s to `Rc<Recipe>`, giving us type-level assurance that alias resolution was performed, and avoiding the need to look up alias targets in a separate table when running. 2019-11-21 07:39:32 -08:00			`Alias(Alias<'src, Name<'src>>),`

Resolve recipe dependencies (#547) Make analysis resolve recipe dependencies from names (`Name`) to recipes (`Rc<Recipe>`), to give type-level certainty that resolution was performed correctly and remove the need to look up dependencies on run. 2019-11-21 06:23:32 -08:00			`Recipe(Recipe<'src, Name<'src>>),`
Add `shell` setting (#525) Add a `set SETTING := VALUE` construct. This construct is intended to be extended as needed with new settings, but for now we're starting with `set shell := [COMMAND, ARG1, ...]`, which allows setting the shell to use for recipe and backtick execution in a justfile. One of the primary reasons for adding this feature is to have a better story on windows, where users are forced to scrounge up an `sh` binary if they want to use `just`. This should allow them to use cmd.exe or powershell in their justfiles, making just optionally dependency-free. 2019-11-10 23:17:47 -08:00			`Set(Set<'src>),`
