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::*;`

Add loader and refactor errors (#917) This commit adds a `Loader` type, which can be used to load multiple source strings. This was done to support the work on modules, but coincidentally enabled consolidating errors, since now `Config::run` can take a `&Loader`, and in the event of an error, return and `Error` that borrows from loaded strings. Multiple error types have been consolidated, and a bunch of ad-hoc error printing was removed. 2021-07-26 01:26:06 -07:00			`pub(crate) fn compile(src: &str) -> CompileResult<Justfile> {`
Gargantuan refactor (#522) - Instead of changing the current directory with `env::set_current_dir` to be implicitly inherited by subprocesses, we now use `Command::current_dir` to set it explicitly. This feels much better, since we aren't dependent on the implicit state of the process's current directory. - Subcommand execution is much improved. - Added a ton of tests for config parsing, config execution, working dir, and search dir. - Error messages are improved. Many more will be colored. - The Config is now onwed, instead of borrowing from the arguments and the `clap::ArgMatches` object. This is a huge ergonomic improvement, especially in tests, and I don't think anyone will notice. - `--edit` now uses `$VISUAL`, `$EDITOR`, or `vim`, in that order, matching git, which I think is what most people will expect. - Added a cute `tmptree!{}` macro, for creating temporary directories populated with directories and files for tests. - Admitted that grammer is LL(k) and I don't know what `k` is. 2019-11-09 21:43:20 -08:00			`let tokens = Lexer::lex(src)?;`
