![]() ![]() Setting this environment variable has the same effect as specifying the -project start-up option, but -project has higher precedence. etc will have JULIA_BINDIR set to /bin, a source-file search path of /share/julia/baseĪnd a global configuration search path of /etc/julia/startup.jl JULIA_PROJECTĪ directory path that indicates which project should be the initial active project. Then Julia searches for a startup.jl file at $JULIA_BINDIR/$SYSCONFDIR/julia/startup.jlīy default (via Base.load_julia_startup()).įor example, a Linux installation with a Julia executable located at /bin/julia, a DATAROOTDIR of. Likewise, the global variable Base.SYSCONFDIR determines a relative path to the configuration file directory. Then the path $JULIA_BINDIR/$DATAROOTDIR/julia/baseĭetermines the directory in which Julia initially searches for source files (via Base.find_source_file()). The global variable Base.DATAROOTDIR determines a relative path from Sys.BINDIR to the data directory associated with Julia. The executable itself is one of $JULIA_BINDIR/julia If $JULIA_BINDIR is not set, then Julia determines the value Sys.BINDIR at run-time. ![]() The absolute path of the directory containing the Julia executable, which sets the global variable Sys.BINDIR. In Bash, environment variables can either be set manually by running, e.g., export JULIA_NUM_THREADS=4 before starting Julia, or by adding the same command to ~/.bashrc or ~/.bash_profile to set the variable each time Bash is started. Some variables, such as JULIA_NUM_THREADS and JULIA_PROJECT, need to be set before Julia starts, therefore adding these to ~/.julia/config/startup.jl is too late in the startup process. ![]() Instrumenting Julia with DTrace, and bpftrace.Reporting and analyzing crashes (segfaults).Static analyzer annotations for GC correctness in C code.Proper maintenance and care of multi-threading locks.printf() and stdio in the Julia runtime.Talking to the compiler (the :meta mechanism).High-level Overview of the Native-Code Generation Process.Noteworthy Differences from other Languages.Multi-processing and Distributed Computing.Mathematical Operations and Elementary Functions. ![]()
