Atom package for evaluating simple mathematical expressions using Math.js

atom-math's Issues

Input view for commands

It could be good to get a droppable input view where commands can be inserted, to be used when it's not desired to insert text in the current buffer.
An icon could be added to the status bar.

Output console messages

It might be nice to wrap console.log to return output messages instead of just returning the result only. As I recall, it's a little awkward since the way in which console interacts with arguments isn't fully covered by standards so it takes some care to do properly. Otherwise perhaps there's another way to intercept and forward these messages to the output.

Definite integration

As note, integration support could be achieved with external packages such as this one, using the same interface.

f(x) = cos(1/x) * x
> saved
integrate(f, 0, 1, 0.01)
...

Print list of new functions

Some inner commands should be specified, so that internal logic could be added to the package. An example is the command to print a list of all defined functions.

f(x) = x + 1
> saved
g(x) = x + 2
> saved
1 + 2
> 3
/printFunctions
> f(x) = x + 1
> g(x) = x + 2

Read full buffer into the `atom-math` history

It could be nice to have a way of loading a full buffer into the atom-math history, so commands and functions could be permanently saved as files.

Function evaluation

Next big improvement to the package would be function evaluation in an easy, user-friendly fashion.

My approach would go for declaring a function and then evaluate it according to the passed values, such as:

f(x) = x + 3
> f(x) saved
compute(f, 39)
> f(39) = 42

Maybe, a query on the available functions could also be possible, like:

...
symbols
> f(x) // f(y) // g(z)

History

Command history should be available with some hotkey in the text editor. Early development stage takes ctrl-up and ctrl-down to navigate through the history. Full history should be available when typing history in the buffer?

Core commands not evaluated when spaced on the left

When a core command has to be evaluated, it generates wrong syntax if there are white spaces on the left.

   1 + 2
   > 3
   /help
   > wrong syntax

Commands should be trimmed before evaluation.
