Renderer command line interface

[Siemienik]

Introduction

Solving this issue should allow using xlsx-renderer from the command line.

Example:

proposed usages:

# Basic
sxr template.xlsx '{"jsonData":true"}' > output.xlsx
sxr -o output.xlsx  template.xlsx '{"jsonData":true"}'
cat vm.json | sxr template.xlsx > output.xlsx

# More advanced
sxr --model vm.json template.xlsx > output.xlsx
sxr --type json --model vm.json template.xlsx > output.xlsx
sxr --type xml --model vm.xml template.xlsx > output.xlsx
sxr --type xml template.xlsx '<someData></someData>'  > output.xlsx 
sxr --type xml --model vm.xml -o output.xlsx template.xlsx 


# Example how it will work with Xlsx-import-cli (sxi)
sxi -d books-def.json input.xlsx | sxr template.xlsx > beauty-books.xlsx

command body:

sxr [options] <template> [model]

Arguments

• <template> indicate which file is used as the template
• [model] view model as a json used to generate a spreadsheet,

Options

• -o --output <filename> write to filename
• -m --model <filename> read filename as a [model] (using both is denied)
• -o --output <filename> write result into filename
• Proposal: -t --type <type: json|xml> specify parser for a model, default it is a JSON.
