scrii_fmt — source formatter

scrii_fmt is a standalone source-code formatter for Scrii. It reads Scrii
source and rewrites it into a canonical style — indentation, spacing,
line-wrapping, and object-literal formatting — so that code written by
different people looks the same.

Build

From the repository root (as part of the full build):

cmake --build build --target scrii_fmt

Or standalone — the formatter builds its own copy of the core library:

cmake -S formatter -B formatter/build
cmake --build formatter/build

Usage

scrii_fmt                     # format stdin -> stdout
scrii_fmt file.scr            # format in place
scrii_fmt -c file.scr         # check mode: exit 1 if changes needed
scrii_fmt -w 100 file.scr     # max line width (default 88)
scrii_fmt -i 4 file.scr       # indent width (default 2)
scrii_fmt -h / --help         # help

Common workflows:

• Format a file in place: scrii_fmt path/to/file.scr
• CI check: scrii_fmt -c path/to/file.scr — exit code 1 when changes
  are needed, so it can gate merges (loop over files in shell; there is no
  directory mode — one file per invocation, or pipe through
  stdin/stdout): scrii_fmt < in.scr > out.scr

Behavior

• Never splits string literals. Long lines wrap at spaces with a
  continuation indent proportional to the configured indent width.
• Object literals expand onto multiple lines when they exceed the line width;
  block braces (if, for, …) never expand.
• Ternary colons and method-call colons are formatted distinctly from object
  key/value separators, so cond ? a : b, x:foo(), and {k: v} are all
  handled correctly.
• Formatting is idempotent: it iterates to a fixed point, so running it
  twice is the same as running it once.

Editor integration

The formatter is a plain command-line tool, so wire it into any editor as an
external formatter.
