Getting Started

Install

Pre-built binaries

Pre-built binaries for Linux and macOS on x86_64 are available alongside each release. We also have a script for downloading and installing pre-built versions:

/bin/bash -c "$(curl -fsSL https://seq-lang.org/install.sh)"

This will install Seq in a new .seq directory within your home directory.

Building from source

See Building from Source.

Usage

The seqc program can either directly run Seq source in JIT mode:

seqc run myprogram.seq

The default compilation and run mode is debug (-debug). Compile and run with optimizations with the -release option:

seqc run -release myprogram.seq

seqc can also produce executables (ensure you have clang installed, as it is used for linking):

# generate 'myprogram' executable
seqc build -exe myprogram.seq

# generate 'foo' executable
seqc build -o foo myprogram.seq

seqc can produce object files:

# generate 'myprogram.o' object file
seqc build -obj myprogram.seq

# generate 'foo.o' object file
seqc build -o foo.o myprogram.seq

seqc can produce LLVM IR:

# generate 'myprogram.ll' object file
seqc build -llvm myprogram.seq

# generate 'foo.ll' object file
seqc build -o foo.ll myprogram.seq

Compile-time definitions

seqc allows for compile-time definitions via the -D flag. For example, in the following code:

from bio import *
print Kmer[SEED_LEN]()

SEED_LEN can be specified on the command line as such: seqc run -DSEED_LEN=10 myprogram.seq.
