11 - Developing Julia packages
Patching other people packages:
pkg>
develop pkgName[patch & commit]
using PkgDev; PkgDev.submit(pkgName)
Develop your own project and publish a new version
pkg>
develop git@github.com:userName/pkgName.jl.gitto checkout master from GitHub[...work on the project..]
PkgDev.tag(pkg, v"0.X.X")PkgDev.publish(pkg)
or (much better) use the package Registrator that automatise the workflow (after you installed Registrator on your GitHub repository, just create a new GitHub release in order to spread it to the Julia package ecosystem).
Testing a package:
Pkg.test("pkg")
It is a good practice to document your own functions. You can use triple quoted strings (""") just before the function to document and use Markdown syntax in it. The Julia documentation recommends that you insert a simplified version of the function, together with an Arguments and an Examples sessions.
For example, this is the documentation string of the ods_readall function within the OdsIO package:
"""ods_readall(filename; <keyword arguments>)Return a dictionary of tables|dictionaries|dataframes indexed by position or name in the original OpenDocument Spreadsheet (.ods) file.# Arguments* `sheetsNames=[]`: the list of sheet names from which to import data.* `sheetsPos=[]`: the list of sheet positions (starting from 1) from which to import data.* `ranges=[]`: a list of pair of touples defining the ranges in each sheet from which to import data, in the format ((tlr,trc),(brr,brc))* `innerType="Matrix"`: the type of the inner container returned. Either "Matrix", "Dict" or "DataFrame"# Notes* sheetsNames and sheetsPos can not be given together* ranges is defined using integer positions for both rows and columns* individual dictionaries or dataframes are keyed by the values of the cells in the first row specified in the range, or first row if `range` is not given* innerType="Matrix", differently from innerType="Dict", preserves original column order, it is faster and require less memory* using innerType="DataFrame" also preserves original column order# Examples``juliajulia> outDic = ods_readall("spreadsheet.ods";sheetsPos=[1,3],ranges=[((1,1),(3,3)),((2,2),(6,4))], innerType="Dict")Dict{Any,Any} with 2 entries:3 => Dict{Any,Any}(Pair{Any,Any}("c",Any[33.0,43.0,53.0,63.0]),Pair{Any,Any}("b",Any[32.0,42.0,52.0,62.0]),Pair{Any,Any}("d",Any[34.0,44.0,54.…1 => Dict{Any,Any}(Pair{Any,Any}("c",Any[23.0,33.0]),Pair{Any,Any}("b",Any[22.0,32.0]),Pair{Any,Any}("a",Any[21.0,31.0]))``"""
