This is a part of the [struct] module in the [tcllib] distribution.

Documentation for this package can be found at

Here we provide only a quick overview. The package provides a single ensemble command, '''struct::list''', which provides the following methods:

   * assign sequence varname  ? varname ? ...
   * dbJoin  ? -inner|-left|-right|-full ?   ? -keys varname ?  {keycol table}...
   * dbJoinKeyed  ? -inner|-left|-right|-full ?   ? -keys varname ?  table...
   * equal a b
   * filter sequence cmdprefix
   * filterfor var sequence expr
   * firstperm list
   * flatten  ? -full ?   ? -- ?  sequence
   * fold sequence initialvalue cmdprefix
   * foreachperm var list body
   * iota n
   * lcsInvert lcsData len1 len2
   * lcsInvert2 lcs1 lcs2 len1 len2
   * lcsInvertMerge lcsData len1 len2
   * lcsInvertMerge2 lcs1 lcs2 len1 len2
   * longestCommonSubsequence sequence1 sequence2  ? maxOccurs ?
   * longestCommonSubsequence2 sequence1 sequence2  ? maxOccurs ?
   * map sequence cmdprefix
   * mapfor var sequence script
   * nextperm perm
   * permutations list
   * repeat size element1 ? element2 element3 ... ?
   * repeatn value size...
   * reverse sequence
   * shift listvar
   * split sequence cmdprefix ?passVar failVar?
   * swap listvar i j

The prefix ''lcs'', as used by a number of the methods above, stands for '''longest common subsequence'''.
