Linux x86_64 standalone binary — v0.1.0

BLT ships as a single self-contained executable — no Python install, no pip, no virtualenv. The binary bundles the Python interpreter, every dependency, and the BLT source tree into one ELF. Drop it on $PATH, mark it executable, run.

Format	Size	Download	Checksum
Standalone binary (Linux x86_64)	~27 MB	blt	.sha256

Verify the download

Confirm the binary you fetched matches the published artefact before running it:

sha256sum -c <(curl -fsSL https://www.oninit.com/blt/download/blt.sha256)
# blt: OK

Expected sha256 for v0.1.0:

47090354d88a349548cd4e8eff30bc6274af743de2e6be47cba6662490d5b6b2  blt

Install order

BLT is one ELF file. Download, place on $PATH, mark executable. No postinstall hook, no shared library, no runtime config.

Distro	Install
Linux x86_64 (any glibc ≥ 2.31)	curl -fLO https://www.oninit.com/blt/download/blt && sudo install -m 755 blt /usr/local/bin/blt

Verify with blt version — expects 0.1.0 printed.

Optional — sql2html for Informix DDL parsing

BLT shells out to sql2html when present at /usr/local/bin/sql2html for Informix-flavour DDL parsing. The fallback is sqlglot, which doesn't understand Informix-specific syntax like USING BTREE and emits warnings.

Recommended — install sql2html from its own download page: /sql2html. No BLT side configuration needed; the auto-detect picks it up.

First run — printers worked example

A canonical worked example ships under examples/printers.* in the source tree (clone from the project repo or grab the snapshot linked below). Minimal config:

mode: recovery
inputs:
  source_4gl:
    paths:
      - examples/printers.4gl
      - examples/printers.per
  schema_ddl:
    paths: [examples/printers.sql]
    parser: sql2html
output:
  directory: ./report/

Then:

blt validate-config printers.yaml
blt run printers.yaml
ls report/
# spec.json  spec.md  review.md  code_spec.json

Output:

mode: recovery
facts: 226
claims: 50
review items: 0
output: ./report
