Decimals without zero don't work

[eduardoarandah]

Command AutoCalcAppendWithEq doesnt work with:

.5 + .5

but work fine with

0.5 + 0.5

[sk1418]

cannot be reproduced.
visual selected .5 + .5 and press <leader>?=, the text turns into .5 + .5 = 1

[eduardoarandah]

for me doesn't work with any engine

 <Leader>v?
 <Leader>b?
 <Leader>p?

What can I do to debug?

VIM 8.1 windows 32bits with python, python3

sorry it is hard for me to test under Windows system since I don't have one. I guess the .5 + .5 expression cannot be evaluated on your system. This express is valid for vim, that is, vim engine won't work. However it should go with bc and python. What you can try is, add some echo to see how it worked for bc engine: https://github.com/sk1418/HowMuch/blob/master/autoload/HowMuch.vim#L285 And do the same for py engine: https://github.com/sk1418/HowMuch/blob/master/autoload/HowMuch.vim#L301

If you confirmed it as a bug and can fix it, a pull request is highly welcomed.

open the howmuch.vim under

[eduardoarandah]

didn't work with python.

I put some echo expr but they don't show in command line. then put some echo "ok" and they show but quickly dissapear.

I'd like to help but I'm a newbie for vim script/debugging jeje

have any material on vim lang?

:h echom

and

 :h a:var

Sorry, I have vim with python3 so python engine didn't detect it, so it wasn't a python error (same for bc) so this returned error (didn't see the message about not having python though)

  if !has('python')
    echoerr HowMuch#errMsg('vim was not compiled with +python!')
    return 'Err'
  endif

for vim engine, I get this

but this works:

If you don't get the same result, there's something strange with my vim version.

What I wrote before:

This expression is valid for vim

In fact I meant "This expression is NOT valid for vim" or "invalid", sorry for the confusing.
