| Summary | 0000095: Possibility to specify catcode table when setting a toks register from Lua | ||||
| Description | Currently, when setting a toks register from Lua using tex.toks[...] = ... or tex.settoks(...), the catcodes of the characters are set to 10 (spaces) and 12 (everything else), respectively. This makes it difficult to pass data from Lua to TeX using toks registers, since i.e. control sequences are \string-ified. It would be great if the mechanism for setting toks registers was extended, so that an optional catcode table could be specified, i.e: tex.settoks(<catcode table>, <string>) This catcode table would then be used for tokenizing the Lua string. | ||||

Actually, the toks registers will move away from pure strings and start using tokenlist tables instead. At the same time, there will be a converter from strings to tokenlists that will indeed allow setting an explicit catcode table. So you will get something like tex.toks[0] = tex.scan_toks (<catcode table>, "....") Sounds reasonable? |

It does indeed, although I'm a bit worried about performance, since if I understand correctly the tokenlist table will be purely temporary and converted into another data structure internal to TeX. |

implemented: tex.scantoks("global",register,cct,"string") |
