src/ez/start.bend checks

raw source on the hub · import 0x74799d3f846634a3d7461d4336d7c9d4/src/ez/start.bend as Start

ez/start: what ez check, ez build and ez run start, decided from the ledger they read and the words they were given. Each starts one bend on the entry the ledger names, or refuses and starts nothing when there is no ez.toml or it does not parse, as cargo refuses a directory with no Cargo.toml. The interpreter (ez/cmd.bend) reads ez.toml, puts the project's BEND_LIB in front of the line (Env.line), runs it and exits; that it does so faithfully is EZ-TRUST-2.

why a directory with no ez.toml is refused

the entry file a ledger names, or "main.bend" when it names none

@ledger:0x74799d3f846634a3d7461d4336d7c9d4/src/ledger/manifest.Manifest -> String

the name a ledger that parsed gives the package

def build.named source · line 57 · raw

@+name:String -> String

where a build lands when nothing said: bin/<package name>.out. The name and not the entry file, because the entry is where a program starts and the name is what it is called: a package named bolt with its entry at bolt/main.bend builds bin/bolt.out and not bin/main.out.

def build.out source · line 61 · raw

@+at:String -> @+name:String -> String

where a build lands: what was asked for, or the default

@ask:Ask -> @+ledger:0x74799d3f846634a3d7461d4336d7c9d4/src/ledger/manifest.Manifest -> List<&2, String>

the line each command starts bend with, over a ledger that parsed: the entry checked into .ez/check.js and never run, built to a native binary, or run with every word after run (EZ-TOOL-9)

@+ask:Ask -> @ledger:0x74799d3f846634a3d7461d4336d7c9d4/src/ledger/manifest.Read -> Start

what a command does with the ledger it read

what a command does with ez.toml's text, None when there is none

@start:Start -> @program:U32 -> U32

the status ez run exits with, given the status of the program it started (EZ-OUT-1): 1 for a refusal, which started none, and the program's own status otherwise, as cargo run exits. ez check and ez build end on what bend printed instead (ez/ends.bend).

def why source · line 104 · raw

@start:Start -> String

why a command refused, or "" when it started bend
