compconf

compconf enables flexible, type-rich comptime configuration of Cerebras Software Language (CSL) projects

• Free software: MIT license

Usage

compconf wraps the cslc compiler, forwarding all non-compconf flags.

python3 -m compconf --compconf-jq '. += {"baz:f32": 42.0}'

Access configuration values in csl code using the compconf module.

const compconf = @import("compconf.zig");

fn main() void {
    @comptime_print(compconf.get_value("baz", f32));
    @comptime_print(compconf.get_value_or("bar", @as(f16, 24.0)));
}

The compconf module provides the following functions:

fn get_value(comptime field_name: comptime_string, comptime T: type) T

fn get_value_or(
    comptime field_name: comptime_string, comptime default_value: anytype
) @type_of(default_value)

Available options:

usage: __main__.py [-h] [--compconf-cslc COMPCONF_CSLC] [--compconf-data COMPCONF_DATA] [--compconf-dump COMPCONF_DUMP] [--compconf-jq COMPCONF_JQ] [--compconf-verbose]
                   [--import-path IMPORT_PATH]

compconf enables flexible, type-rich comptime configuration of csl projects.

options:
  -h, --help            show this help message and exit
  --compconf-cslc COMPCONF_CSLC
                        compiler command to run
  --compconf-data COMPCONF_DATA
                        json data file to read, if any
  --compconf-dump COMPCONF_DUMP
                        path to dump the final json data
  --compconf-jq COMPCONF_JQ
                        jq command to add/modify data (e.g., '. += {"foo:u32": 42}')
  --compconf-verbose    enable verbose logging
  --import-path IMPORT_PATH
                        additional import paths for cslc

JSON data must be formatted according to `@import_comptime_value` conventions from Cerebras SDK v1.X. See
