FMPP Content Generate(1)Installation and Introduction

FMPP is using template engine FreeMarker. It can insert data from sources like CSV, XML and JSON into the generated files.

Download the latest Source and Package
> wget https://versaweb.dl.sourceforge.net/project/fmpp/fmpp/0.9.16/fmpp_0.9.16.tar.gz

Or we can get source codes here
https://github.com/freemarker/fmpp
https://github.com/freemarker/fmpp/tree/master/src/docs/examples

> git clone https://github.com/freemarker/fmpp

Follow document try to build that from master
https://github.com/freemarker/fmpp/blob/master/BUILD.txt
> java -version
java version "1.8.0_161"

> ant -version
Apache Ant(TM) version 1.10.3 compiled on March 24 2018

Prepare the build file
> cp build.properties.sample build.properties

It is not that easy to solve the dependency issues.
Unzip the file and put into working directory
> sudo ln -s /Users/hluo/tool/fmpp-0.9.16 /opt/fmpp-0.9.16
> sudo ln -s /opt/fmpp-0.9.16 /opt/fmpp

Add to PATH, check the installation and version
> fmpp --version
FMPP version 0.9.16, build 2018-09-03T21:47:30Z
Currently using FreeMarker version 2.3.28
For the latest version visit: http://fmpp.sourceforge.net/

Create a demo directory named fmppdemo
Create some working directory in that project
fmppdemo/data/hellosillycat.csv
fmppdemo/data/hellosillycat.tdd
fmppdemo/out
fmppdemo/src/hellosillycat.ftl
fmppdemo/config.fmpp

Here is some details for these files
hellosillycat.tdd is the data file, it can be JSON format data
{
    user: "Yiyi Kang"
    work: "Cloudsnap"
}

hellosillycat.csv is the data file as well, it just can be exported from MySQL database
user;work
Yiyi Kang;Lablue
hellosillycat.ftl is the template for our project, it supports free marker
<html>
    <head>
        <title>fmpp generate html</title>
    </head>
    <body>
        <h1>Welcome ${user}</h1>
        <p>Happy workday in ${work}</p>

        <table border=1>
          <tr><#list csv.headers as h><th>${h}</#list>
        <#list csv as row>
          <tr><#list csv.headers as h><td>${(row[h]!"N/A")?string}</#list>
        </#list>
    </body>
</html>

So fmpp will load the data from data directory, following the template in FTL and generate all the html in out directory.
config.fmpp is the configuration for how to generate
sourceRoot: src
outputRoot: out
logFile: log.fmpp
modes: [
    execute(*.ftl)
]
replaceExtensions:[ftl, html]
data: {
    tdd(../data/hellosillycat.tdd)
    csv: csv(../data/hellosillycat.csv)
}

Some other details in Data Loader
http://fmpp.sourceforge.net/dataloader.html#key_csv

Multiple Files
http://fmpp.sourceforge.net/qtour.html#sect4

For CSV, we can load different set of data.
data: {
    tdd(../data/hellosillycat.tdd)
    csv: csv(../data/hellosillycat.csv)
    devices: csv(../data/devices.csv)
}

For template files, we can generate a lot of different files according to the same template from different data records.
<@pp.dropOutputFile />
<#list devices as device>
<@pp.changeOutputFile name=device.deviceName+".html" />
<html>
    <head>
      <title>${device.deviceName?cap_first}</title>
    </head>
    <body>
        <h1>${device.deviceName?cap_first}</h1>
          <p>${device.ip}</p>
    </body>
</html>
</#list>

I will create a file in easy/easyfmpp
