Acute Markup Language

Dev Build Status (Github Actions) Test Coverage

AcuteML is an Acute Markup Language (AML) for Web/XML development in Julia.

  • It automatically creates or extracts HTML/XML files from Julia types!

  • It also has a general templating engine, which can be used for any type of documents.

Installation and Usage

using Pkg
Pkg.add("AcuteML")
using AcuteML

See Type Definition for a comprehensive introduction to syntax. You can use @aml macro to define a Julia type, and then the package automatically creates a xml or html associated with the defined type.

Readme Content

Example - Simple

using AcuteML
@aml mutable struct Body "~"
    h1, "~"
    p::Vector{String}, "~"
end

@aml mutable struct Page doc"html"
    body::Body, "~"
end

b = Body(h1 = "My heading", p = ["Paragraph1", "Paragraph2"])
d = Page(body = b)
pprint(d)
julia> pprint(d)
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html>
  <Body>
    <h1>My heading</h1>
    <p>Paragraph1</p>
    <p>Paragraph2</p>
  </Body>
</html>

More advanced Examples are given in the following:

Example - Struct Definition

First, we define the structs using @aml to store the data in:

using AcuteML

# Types definition

# Person Type
@aml mutable struct Person "person", check_course
    age::UInt64, "~"
    field, "study-field"
    GPA::Float64 = 4.5, "~", GPAcheck
    courses::Vector{String}, "taken-courses"
    professors::UN{DataFrame} = nothing, "table"
    id::Int64, att"~"
    comment::UN{String} = nothing, txt"end"
end

@aml mutable struct University doc"university"
    name, att"university-name"
    people::Vector{Person}, "person"
end

# Value Checking Functions
GPAcheck(x) = x <= 4.5 && x >= 0

function check_course(age, field, GPA, courses, professors, id, comment)

    if field == "Mechanical Engineering"
        relevant = ["Artificial Intelligence", "Robotics", "Machine Design"]
    elseif field == "Computer Engineering"
        relevant = ["Julia", "Algorithms"]
    else
        error("study field is not known")
    end

    return any(in.(courses, Ref(relevant)))
end

Example - Creator

After we defined the structs, we can create instances of them by passing our data to the fields:

P1 = Person(age=24, field="Mechanical Engineering", courses = ["Artificial Intelligence", "Robotics"], id = 1, comment = "He is a genius")
P2 = Person(age=18, field="Computer Engineering", GPA=4, courses=["Julia"], id = 2)

U = University(name="Julia University", people=[P1, P2])

U.people[2].GPA=4.2 # mutability support after Doc creation
# An example that doesn't meet the criteria function for GPA because GPA is more than 4.5
P3 = Person(age=99, field="Macro Wizard", GPA=10, courses=["Julia Magic"], id = 3)
julia>
GPA doesn't meet criteria function
julia> pprint(P1) # or print(P1.aml)
<person id="1">
  <age>24</age>
  <study-field>Mechanical Engineering</study-field>
  <GPA>4.5</GPA>
  <taken-courses>Artificial Intelligence</taken-courses>
  <taken-courses>Robotics</taken-courses>
  He is a genius
</person>

julia> pprint(U) # or print(U.aml)
<?xml version="1.0" encoding="UTF-8"?>
<university university-name="Julia University">
  <person id="1">
    <age>24</age>
    <study-field>Mechanical Engineering</study-field>
    <GPA>4.5</GPA>
    <taken-courses>Artificial Intelligence</taken-courses>
    <taken-courses>Robotics</taken-courses>
    He is a genius
  </person>
  <person id="2">
    <age>18</age>
    <study-field>Computer Engineering</study-field>
    <GPA>4.2</GPA>
    <taken-courses>Julia</taken-courses>
  </person>
</university>

P3 with Tables.jl type:

Profs1 = DataFrame(course = ["Artificial Intelligence", "Robotics"], professor = ["Prof. A", "Prof. B"] )

P3 = Person(age=24, field="Mechanical Engineering", courses = ["Artificial Intelligence", "Robotics"], professors= Profs1, id = 1)
julia> pprint(P3)

<person id="1">
<age>24</age>
<study-field>Mechanical Engineering</study-field>
<GPA>4.5</GPA>
<taken-courses>Artificial Intelligence</taken-courses>
<taken-courses>Robotics</taken-courses>
<table>
<tr class="header">
<th style="text-align: right; ">course</th>
<th style="text-align: right; ">professor</th>
</tr>
<tr class="subheader headerLastRow">
<th style="text-align: right; ">String</th>
<th style="text-align: right; ">String</th>
</tr>
<tr>
<td style="text-align: right; ">Artificial Intelligence</td>
<td style="text-align: right; ">Prof. A</td>
</tr>
<tr>
<td style="text-align: right; ">Robotics</td>
<td style="text-align: right; ">Prof. B</td>
</tr>
</table>
</person>

Example - Extractor

After we defined the structs, we can automatically extract and store the data in their fields:

using AcuteML

xml = parsexml("""
<?xml version="1.0" encoding="UTF-8"?>
<university university-name="Julia University">
  <person id="1">
    <age>24</age>
    <study-field>Mechanical Engineering</study-field>
    <GPA>4.5</GPA>
    <taken-courses>Artificial Intelligence</taken-courses>
    <taken-courses>Robotics</taken-courses>
    He is a genius
  </person>
  <person id="2">
    <age>18</age>
    <study-field>Computer Engineering</study-field>
    <GPA>4.2</GPA>
    <taken-courses>Julia</taken-courses>
  </person>
</university>
""")

# extract University
U = University(xml) # StructName(xml) extracts the data and stores them in proper format

# Now you can access all of the data by calling the fieldnames

julia>U.name
"Julia University"

# extract Person
P1 = U.people[1]

julia>P1.age
24

julia>P1.field
Mechanical Engineering

julia>P1.GPA
4.5

julia>P1.courses
["Artificial Intelligence", "Robotics"]

julia>P1.id
1

julia> P1.comment
"He is a genius"

Templating

AcuteML also provides a templating engine if you want to use templates instead of creating the types.


Example - Template Rendering using Functions

This method only uses functions that return string. You can build your desired string and call the function for rendering.

## create person function to store out html template
newTemplate("person", :function)


function person(;id, age, field, GPA, courses)

  # Build the taken courses section
  loopOut=""
  for course in courses
    loopOut = loopOut * """ <taken-courses>$(course)</taken-courses>   """
  end

  # Append all the sections and variables together
  out = """
  <person id=$(id)>
    <age>$(age)</age>
    <study-field>$(field)</study-field>
    <GPA>$(GPA)</GPA>
    $loopOut
  </person>
  """

  return out
end

# Call the function for rendering
out = person(
  id = "1",
  age = "24",
  field = "Mechanical Engineering",
  GPA = "4.5",
  courses = ["Artificial Intelligence", "Robotics"]
)

print(out)

# you can also write the output to a file:
Base.write(filePath, out)

Example - Template Rendering using Files

You can render variables into html/xml files. However, you can't have multiline control flow Julia code in this method.

# you can create a file and edit the file directly by using
newTemplate("person")

# Add the following html code to the generated html file
#=
<person id=$(id)>
  <age>$(age)</age>
  <study-field>$(field)</study-field>
  <GPA>$(GPA)</GPA>
  <taken-courses>$(courses[1])</taken-courses>
  <taken-courses>$(courses[2])</taken-courses>
</person>
=#

# Specify the template (or its path), and also the variables for rendering
out =render2file("person", false,
  id = 1,
  age = 24,
  field = "Mechanical Engineering",
  GPA = 4.5,
  courses = ["Artificial Intelligence", "Robotics"])

# you pass `true` as the 2nd argument to overwrite person.html statically.
