Maxima CAS (wxMaxima): run via the command line

20 Sep 2018, 13:41

- Maxima CAS (wxMaxima) is a freeware computer algebra system (cf. Mathematica, MATLAB).
- It has a GUI, but it can be useful to do calculations via the command line instead.
- Here is a script to demonstrate how it can be used via the command line.

Code: Select all

;to run Maxima/wxMaxima via the command line manually:
;press Win+R, type cmd [and press Enter]
;type cd C:\maxima-5.39.0\bin [or the appropriate folder] [and press Enter]
;type maxima [and press Enter]
;type 1+1;2+2;3+3;4+4;5+5; [and press Enter]
;type quit(); [and press Enter]

q:: ;run Maxima/wxMaxima via the command line
vPathExe := "C:\maxima-5.39.0\bin\maxima.bat"
vScript := "1+1;2+2;3+3;4+4;5+5;quit();"

DetectHiddenWindows, On
vComSpec := A_ComSpec ? A_ComSpec : ComSpec
Run, % vComSpec,, Hide, vPID
WinWait, % "ahk_pid " vPID
DllCall("kernel32\AttachConsole", "UInt",vPID)
oShell := ComObjCreate("WScript.Shell")
oExec := oShell.Exec(Chr(34) vPathExe Chr(34))
oExec.StdIn.Write(vScript)
oExec.StdIn.Close()
vStdOut := oExec.StdOut.ReadAll()
DllCall("kernel32\FreeConsole")
Process, Close, % vPID
oShell := oExec := ""
MsgBox, % vStdOut
return
QUERIES

- How to get the input text *and* output text (as displayed in the command prompt).
- How to ignore the initial text. I.e. can you launch it, and 'clear' the StdOut text at that point in order to skip that text.
- Can you perform an input and get the output, then perform an input and get the output etc.
