Run an expression with automatic data read logging

Evaluates expr with a local read() binding tied to log, so calls inside the block don't need to repeat the log argument. Reads must use read() explicitly inside the block; calling a reader function directly (e.g. bare haven::read_sas(...)) is not logged. This keeps logging coverage unambiguous: every logged read is visible at the call site, and there are no implicit gaps.

Usage

with_log(log, expr)

Arguments

log

A regulog object.

expr

An expression, typically a {} block. Inside the block, read(reader, ...) is available and logs to log automatically.

Value

The value of expr, invisibly.

Examples

log <- regulog_init(app = "pipeline", version = "1.0", user = "jsmith")

if (FALSE) { # \dontrun{
with_log(log, {
  adsl <- read(haven::read_sas, "data/adsl.sas7bdat")
  adae <- read(haven::read_sas, "data/adae.sas7bdat")
})

filter_log(log, action = "data_read")
} # }
