etextools provides many (purely expandable) tools for LaTeX:
- Extensive list management (csv lists, lists of single tokens/characters, etoolbox lists):
   . purely expandable loops (csvloop, forcsvloop etc.)
   . conversion (csvtolist etc.))
   . addition/deletion (csvadd, listdel etc.)
- Expansion and groups control : \expandnext, \ExpandAfterCmds, \AfterGroup...
- Tests on tokens, characters and control sequences (\iffirstchar, \ifiscs, \ifdefcount, \@ifchar...)
- Tests on strings (\ifstrnum, \ifuppercase, \DeclareStringFilter...)
- Purely expandable macros with options (\FE@testopt, \FE@ifstar) or modifiers (\FE@modifiers)
- Some purely expandable numerics (\interval, \locinterplin)
