Cudatext: Plugin 'Calc Expression' with culture specific data formats

[jczanfona]

It would be nice if the 'Calc Expression' plugin was configurable to set the decimal and thousand separators.

And, it may also be a good idea to define the texts to skip ($, €, kg, ...).

I think that via config plugin is the best way, more flexible, better than use the _locale_ module of python (although it can take the initial values from there).

I can add 2 options: decimal_separator, thousand_separator.
It is some work so i will do it for donation http://uvviewsoft.com/donate.htm , e.g. $20
Not sure it's ok to skip any chars, better to show error and not calculate.

[jczanfona]

Only PayPal... Is it possible?

[Alexey-T]

yes, payment method Paypal is available for UV Pro program.

[jczanfona]

Done!

Plugin is updated! see new readme.txt file.

plugin for CudaText.
reads selected text as math expression, e.g. "2.4*sin(pi/3)" and evaluates it by Python.
tries to use "safe evaluation", without dangerous python functions enabled.
gives commands (menu Plugins / Calc Expression) to replace selection with number result,
or just show the result in the statusbar.

these Python functions are supported:

  abs      cosh       frexp      pow
  acos     degrees    hypot      radians
  asin     e          ldexp      sin
  atan     exp        log        sinh
  atan2    fabs       log10      sqrt
  ceil     floor      modf       tan
  cos      fmod       pi         tanh

  min(x1, x2, ...)
  max(x1, x2, ...)
  sum( [x1, x2, ...] )
  mean( [x1, x2, ...] )
  median( [x1, x2, ...] )

details:
https://docs.python.org/3/library/math.html
https://docs.python.org/3/library/statistics.html

plugin has config file, call menu item "Options / Settings-plugins / Calc Expression / Config".
it has separator options:
  [calc_expression]
  decimal_separator=.
  thousand_separator=
  list_separator=,

decimal_separator can be changed to e.g. "," or another.
thousand_separator can be set to non-empty, it will be skipped by Python anyway.
list_separator is used in functions with several arguments, e.g. min, max, mean.

[jczanfona]

Please, format the output too (thousand separator)

[Alexey-T]

done, plugin updated.

[jczanfona]

Is everything right?

Same result, for example, with: 1.000+3

[snippet_panel]
folder=HTML - Color names+values

[calc_expression]
decimal_separator=,
thousand_separator=.
list_separator=;

[Alexey-T]

Made a fix-- updated!

[jczanfona]

I leave this simple macro to take better advantage of this plugin.
This macro adds to the selected expression the operator '=' followed by the result

Calc

ed.cmd(cmds.cCommand_ClipboardCopy)
app.app_proc(app.PROC_EXEC_PLUGIN, 'cuda_calc_expr,replace,')
ed.cmd(cmds.cCommand_ClipboardPaste)
ed.cmd(cmds.cCommand_TextInsert,'=')

[Alexey-T]

@kvichans Macro above :)

[jczanfona]

I can't see where is the problem...

wrong: 107.728,09-99.822,66=7.905,42999999999
right: 8,09-2,66=5,43

[Alexey-T]

Pls post the config file of plugin: Cud/settings/plugins.ini

[Alexey-T]

Why wrong? it's ok result, run in console:

Python 3.6.9
Loading toolbar config (21ms)
Startup: total: 810ms, including plugins: 20ms
>>> 107728.09-99822.66
7905.429999999993

[jczanfona]

[snippet_panel]
folder=HTML - Color names+values

[calc_expression]
decimal_separator=,
thousand_separator=.
list_separator=;

[Alexey-T]

See above reply.

[jczanfona]

The result must be 7.905,43
not 7.905,42999999999

[Alexey-T]

Hmm, maybe we can add option "how many digits to show after decimal". and round result.

[jczanfona]

Ok, good idea

[Alexey-T]

But it will give not nice result if this option is too small and expression has big count of digits

[jczanfona]

I don't think it's going to look bad, if it's formatted it will be clear

[Alexey-T]

Plugin updated in GitHub , use Addon Manager/ Install from GitHub - url is in plugin install.inf file
