Bugs item #549226, was opened at 20020426 09:31 Message generated for change (Comment added) made by fjoliveira You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=549226&group_id=4933 Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: Problems with user input Initial Comment:  Some remarks on Userinput of GPL Maxima/Win. (W. Lindner)  Problems with TSETUP(), METRIC(), ENTERTENSOR(), TTRANSFORM() etc.: 1. Studying a Log session of Valerij Pipin, the following behaviour seems intended: (C16) PRINT( Please input tensor name and others,like, name : A; covariant indices: [I,J]; contravariant indices: K; derivative indices: [];, ENTERTENSOR()) Enter tensor name: A; Enter a list of the covariant indices: [I,J]; Enter a list of the contravariant indices: K; Enter a list of the derivative indices: []; K (D16) A I/J Please input tensor name and others,like, name : A; covariant indices: [I,J]; contravariant indices: K; derivative indices: []; A([I, J], [K]) 2. BUT actually it goes like this: (C16) PRINT( Please input tensor name and others,like, name : A; covariant indices: contravariant indices: derivative indices: , ENTERTENSOR()) A; [I,J]; K; [];Enter tensor name: Enter a list of the covariant indices: Enter a list of the contravariant indices: Enter a list of the derivative indices: K (D16) A I J Please input tensor name and others,like, name : A; covariant indices: [I,J]; contravariant indices: K; derivative indices: []; A([I, J], [K]) 3. To sum up, a. ENTERTENSOR() does not make an dialog with the user, but is SEEMS hanging in a loop. Giving the input 'A; [I,J]; K; [];' nevertheless at demo prompt _; (bug in maximal help page: space don't work  use _; !), the input is taken correctly by ENTERTENSOR, and AT THE END all dialog text is shipped out, what makes now no sense, see above. b. Similar behavier found in METRIC(), TTRANSFORM(), TSETUP(): After input METRIC()$, the system seems hanging; giving y; (for YES), the output comes with user query appended (! instead of coming first).

For example, what worked was the following: tsetup();<cr>4;<cr>[r,h,p,t];<cr>1;<cr>1;<cr>A;<cr>r^2;<cr>r^2*sin(h)^2;<cr>D;<cr>depends([A,D],r);<cr>y;<cr>y;<cr> after which the metric tensor and it's inverse were displayed and I could proceed. Upon initial start up of 'xmaximalocal' the following error messages were reported:  maia:maxima5.9.0> Maxima 5.9.0 http://maxima.sourceforge.net Distributed under the GNU Public License.
