mdhost

Runs eshost, displays the table output in the terminal, and generates a Markdown table of a few of the results (JavaScriptCore, SpiderMonkey, and V8), copying it to your clipboard.

Installation

Install via RubyGems:

gem install mdhost

Usage

Single input

Given a single input, mdhost will output the table from eshost -t to your terminal, and will copy to your clipboard a markdown code block containing the relevant eshost command, followed by a markdown table of the results. For example, running this:

mdhost 'Date.parse("0")'

Will output the following markdown to your clipboard:

> eshost -te 'Date.parse("0")'

Engine	Result
JavaScriptCore	-62167219200000
SpiderMonkey	NaN
V8	946710000000

Multiple inputs

You can have multiple unrelated inputs at once, and a more complex table will be generated. For example, running this:

mdhost '"hello"' "42"

Will output the following markdown to your clipboard:

Input	JavaScriptCore	SpiderMonkey	V8
"hello"	hello	hello	hello
42	42	42	42

Format inputs

If you have multiple similar inputs, for example arguments to a function, you can format them into a string passed into the --format or -f parameter. The substring #{} in the format string will be replaced by each of the multiple arguments that follow and arranged into a table. For example, running this:

mdhost -f 'Date.parse("#{}")' "1970-01-01" "Thu 1970-01-01" "Thu Jan.01.1970"

Will output the following markdown to your clipboard:

Input	JavaScriptCore	SpiderMonkey	V8
Date.parse("1970-01-01")	0	0	0
Date.parse("Thu 1970-01-01")	NaN	25200000	25200000
Date.parse("Thu Jan.01.1970")	NaN	25200000	25200000

You can also use the --table-format or -t parameter to specify a different format string for the "Input" column of the table. For example, if you wanted the inputs to the function in the previous example to simply be displayed surrounded by quotation marks, you could run:

mdhost -f 'Date.parse("#{}")' -t '"#{}"' "1970-01-01" "Thu 1970-01-01" "Thu Jan.01.1970"
Date.parse("1970-01-01")

And the following markdown would be output to your clipboard:

Input	JavaScriptCore	SpiderMonkey	V8
"1970-01-01"	0	0	0
"Thu 1970-01-01"	NaN	25200000	25200000
"Thu Jan.01.1970"	NaN	25200000	25200000
