Features

• explicit useful and convenient checks from apenwarr/redo:
  • check that $1 was not touched during .do execution
  • check that stdout and $3 are not written simultaneously
  • check that generated target was not modified "externally" outside the redo, preventing its overwriting, but continuing the build
• targets, dependency information and their directories are explicitly synced (can be disabled, should work faster)
• file’s change is detected by comparing its size, ctime (if REDO_INODE_NO_TRUST environment variable is not set) and BLAKE3 hash
• files creation is umask-friendly (unlike mkstemp() used in redo-c)
• parallel build with jobs limit, optionally in infinite mode
• coloured messages (can be disabled)
• verbose debug messages, including out-of-date determination, PIDs, lock and jobserver acquirings/releases
• displaying of each target’s execution time
• each target’s stderr can be prefixed with the PID
• optional statusline with currently running/waiting/done jobs
• target’s stderr can be stored on the disk with TAI64N timestamp prefixes for each line. To convert them to localtime you can use either tai64nlocal utility from daemontools, or similar one: go get go.cypherpunks.ru/tai64n/cmd/tai64nlocal
