A way to bind dependency information to Julia assets without the need to pass around TOML files.
The use case is that your notebooks would have something like the following in their first cell:
using InstantiateFromURL github_project("QuantEcon/QuantEconLecturePackages")
[Note] To account for changes in
IJulia (where notebooks will now look recursively up the tree for TOML, and use either what they find or the default
v1.x environment), we've introduced the new function/entrypoint below. The functions we had previously provided are still around, in the subsequent deprecated section.
The signature is:
function github_project(reponame; # e.g., "QuantEcon/quantecon-notebooks-jl" path = "", # relative path within the repo (root by default) version = "master", force = false, instantiate = false)
path identify the TOML on the internet. Reponame is something like
"QuantEcon/QuantEconLecturePackages" The path refers to the path to the TOML within the source repo, and is
"" by default (i.e., referring to top-level.)
version refers to a specific version of the TOML, corresponding to a github tag of the
force decides whether or not we're comfortable using whatever project-specific IJulia finds (if there is any.) Essentially, the
force parameter decides whether to use a soft or hard match.
instantiate decides whether or not to instantiate the project upon activation.
The logic here is:
If a local project is activated (i.e., if there is TOML up the source tree), use that unless
force = true, and print intelligent information about it (e.g., if we asked for version
v0.2.1, and version
v0.2.0 is found, it will still use
v0.2.0, and alert you to the difference.)
force = true, then regardless of what is activated, the precise set of
Project.toml, Manifest.toml will be pulled down to the notebook's directory from the specified internet location.
We also defined:
packages_to_default_environment(), which will take the current environment's packages, and
Pkg.add()them to your
v1.xenvironment. Useful for "seeding" or setting up new Julia installs, or making sure that deps for one project are available for other projects, etc.
activate_github, the signature is:
function activate_github(reponame; # like "QuantEcon/QuantEconLecturePackages" tag = nothing, # could be "master" or a git tag sha = nothing, # could point to a specific commit force = false, # will overwrite the local version of this TOML if true add_default_environment = false) # will add these projects to the default (e.g., v1.1) TOML if true
Example calls include:
activate_github("QuantEcon/QuantEconLecturePackages", tag = "master")
activate_github("QuantEcon/QuantEconLecturePackages", tag = "v0.9.5")
activate_github("QuantEcon/QuantEconLecturePackages", sha = "0c2985")
activate_github_path, the signature is:
function activate_github_path(reponame; # something like "QuantEcon/SimpleDifferentialOperators.jl" path = "", # like "docs/examples", or where in the (master) source tree the TOML is tag = "master", force = false, activate = true) # decide whether to `activate; instantiate; precompile` or not
Note: Because switching project files currently leads to repeat precompilations in Julia,
activate will only bind if the current Project.toml (i.e.,
Base.active_project()) is in a different location than the pwd (i.e.,
