BowPad | A simple and fast text editor with a ribbon UI | Editor library

I try using a very light-weighted editor BowPad to edit and run codes.

Take running R as an example, which has been added to Windows PATH Environment Variable D:\R\R-3.6.2\bin\x64

I try to take some following steps:

• I built a test.r writing some testing line codes as 1+2; plot(1:10)
• Menu --> Run --> Configure custom commands
  • Command Name: run R
  • Command Line: D:\R\R-3.6.2\bin\R.exe $(SEL_TEXT)
    • $(LINE) The line where the cursor is
    • $(POS) the position where the cursor is
    • $(TAB_PATH) the path to the file of the active tab
    • $(TAB_NAME) the file name without extension of the current tab
    • $(TAB_EXT) the file extension of the current tab
    • $(TAB_DIR) the directory of the file of the active tab
    • $(SEL_TEXT) the selected text or the word at the cursor position
    • $(SEL_TEXT_ESCAPED) like $(SEL_TEXT) but escaped, useful for urls

When I press to choose run R to run the code, something wrong happens!

• It will open a Rterm(64-bit) window each time when I run R!
• it shows RGUMENT '1+2' __ignored__ or ARGUMENT 'plot(1:10)' __ignored__

Did I missing something ? BTW, can we set some shortcuts keys for running Python, R, Octave or Julia?

Also, when I reach the homepage of BowPad for more information, little usage of this software can be found!
