src/ez/ends.bend checks

raw source on the hub · import 0x74799d3f846634a3d7461d4336d7c9d4/src/ez/ends.bend as Ends

ez/ends: how the commands that are not planners end. ez check and ez build start one bend and end on its answer; ez test and ez prove start one per file and end on the count. Each ends with a P.Outcome, the same end a planner's plan has, and the interpreter exits with its P.status (Run.end), so the status each exits with is a law (EZ-OUT-1). That the answer is what bend printed is EZ-TRUST-2. ez run reads no answer: it exits with the program's own status (code in ez/start.bend).

@passed:Bool -> 0x74799d3f846634a3d7461d4336d7c9d4/src/lock/plan.Outcome

a command that ends on whether it passed: success, or a refusal whose reason was already printed

ez lock --package NAME without --upgrade is a line ez refuses before it reads anything, since --package only filters an upgrade

ez build: bend exited 0

def no.main source · line 44 · raw

@+line:String -> Bool

bend f -o out checks without running main. A clean file prints nothing at all, and a library entry, having no main, checks clean and then exits 1 with "no main to run" from the emit. A check failure throws before the emit, so that message can only follow a check that passed.

It is matched as a whole line, because that is the shape of the thing being claimed: bend prints it as Error: no main to run and nothing else. Asked as a substring of the whole output, the same words appearing anywhere (inside some other error's text, or in a source line bend echoed back while reporting on it) would answer yes and mean nothing, and a failing check would read as a passing one. Two other line-shaped facts in this tree were being asked of whole files the same way, and one of them silently dropped a test before it was caught.

def said.no.main source · line 52 · raw

@ls:List<&2, String> -> Bool

whether any line of the output is that one. The rest of the walk is bound before the Bool.or rather than written under it: Bool.or is an ordinary function and reduces both sides, so a recursive call sitting inside one is not a branch the condition can decline. Bound first it is a plain fold over a handful of lines, which is what the rest of this tree does too.
