l3­ex­per­i­men­tal – Ex­per­i­men­tal LaTeX3 con­cepts

The l3­ex­per­i­men­tal pack­ages are a col­lec­tion of ex­per­i­men­tal im­ple­men­ta­tions for as­pects of the LaTeX3 ker­nel, deal­ing with higher-level ideas such as the De­signer In­ter­face. Some of them work as stand alone pack­ages, pro­vid­ing new func­tion­al­ity, and can be used on top of LaTeX2ε with no changes to the ex­ist­ing ker­nel.
The present re­lease in­cludes: – xgal­ley, which con­trols boxes re­ceiv­ing text for type­set­ting. – l3dt: ker­nel sup­port for data ta­bles; – l3­gal­ley: ker­nel sup­port for xgal­ley; – l3regex: ker­nel sup­port for reg­u­lar ex­pres­sion search and re­place op­er­a­tions; – l3­sort: ker­nel sup­port for sort­ing se­quences, to­ken lists or comma-lists, ac­cord­ing to user-spec­i­fied com­par­i­son cri­te­ria; – l3str: ker­nel sup­port for string ma­nip­u­la­tion; – l3tl-build: ker­nel sup­port for to­ken list build­ing; – l3tl_anal­y­sis: ker­nel sup­port for to­ken list anal­y­sis; and – xcoffins, which al­lows the align­ment of boxes us­ing a se­ries of ‘han­dle’ po­si­tions, sup­ple­ment­ing the sim­ple TeX ref­er­ence point.
All the files of the bun­dle are also avail­able in the Sub­ver­sion (SVN) repos­i­tory of the LaTeX3 Project.
The bun­dle on CTAN is based on a snap­shot of the SVN repos­i­tory on 2012-11-21.
