Name

tsf - type a structured file

Synopsis

tsf in=file [parameter=value] ...

Description

tsf types the contents of a structured binary file (see filestruct(3NEMO) ) in a human readable form on standard output. The type, tag, dimensions (if any) and contents of all items are listed. The contents of CharType items are printed directly; FloatType and DoubleType items are printed in floating-point notation; all other types are printed in octal for portability reasons (but see octal= below). XML format can optionally be selected as well, but this is not been well exercised. A json mode has been considered.

Parameters

The following parameters are recognized in order; they may be given in any order if the keyword is also given. Use --help to confirm this man page is up to date.
in=file
Input data is read from file, which must be a structured binary file.
No default.
maxprec=t|f
If true, print float and double item data with maximum precision.
[Default: f].
maxline=lines
Limits the number of lines of data typed for each item to lines. See also allline= below.
[Default: 4].
allline=t|f
Print all lines, it overrides any value of maxline. If xml format selected, allline will always be set to t.
[Default: f].
indent=set-indent
Amount to indent contents of item-sets.
[Default: 2].
margin=right-margin
Righthand margin for output. Set this to a high value to prevent possible string problems if file needs to be read by rsf.
[Default: 72].
item=item-name
select only this item for output.
Default: all items selected.
xml=t|f
Output in xml mode? If not, old-style human readable tsf mode is selected.
[Default: f].
octal=t|f
Output of (short/long) integers in octal? Old versions used to exchange integer information in octal, we have now switched by default to decimal (more human readable). By using octal=t you can force this program back in the old mode. If take output of tsf to be read into rsf, you now need to force octal=t.
[Default: f].

Debug

debug=2 reports values of MaxSetLen as defined in "filestruct.h". For MaxTagLen and MaxVecDim see rsf(1NEMO) .

Examples

An example of converting all double precision numbers to single precision in a NEMO file: % tsf in=double.dat out=float.dat convert=d2f

Caveats

The algorithm for implementing maxline is crude.

If indent= and margin= are choosen too large, resp. too small, they can bump into each other and cause illegable output, which cannot be read by rsf either.
