Alias limit

In YAML, &name marks a value and *name repeats it somewhere else. The aliases in one file have repeated more than Statac reads: more than 10,000 values, or more than 1 MB of text.

What you’ll see

error  Alias limit: by `*book`, aliases have repeated more than 10,000 values

In the terminal the message also names the file and line where there is one, and marks the exact text.

Why Statac stops

Aliases can repeat aliases, so a few lines can grow into an enormous document that takes all the memory a computer has. Statac stops at the alias that passes the limit instead.

How to fix it

Write the values out where you need them, or repeat fewer of them. A file that needs this many repeats is usually better split into data files.

Example

a: &a [one, one, one, one, one, one, one, one, one, one]
b: &b [*a, *a, *a, *a, *a, *a, *a, *a, *a, *a]
c: &c [*b, *b, *b, *b, *b, *b, *b, *b, *b, *b]
d: [*c, *c, *c, *c, *c, *c, *c, *c, *c, *c]

Each line repeats the one before ten times, so d alone holds more than 10,000 values.

Its name

Name	alias-limit
In the terminal	statac explain alias-limit
To stop showing it	It stops the build, so it can't be quietened.
