[Docutils-users] styling a replacement

[Tom R. <Tom...@po...>]

Can one style a non-link replacement (e.g., emphasize text with a subscript) without a `raw` directive? What I mean:

I see FAQ section 2.16[1]:
> Inline markup can be combined with hyperlinks using substitution definitions and references with the "replace" directive. For example:

However I want to combine inline markup and a substitution providing a subscript, for something like the following reST:

fail1> Cities produce more than 70% of global fossil-fuel |CO2| emissions (*|FFCO2|*). We have cutting-edge science relating how cities and regions settle and use their land (LULC) to their |FFCO2| emissions.

fail1> .. |CO2| replace:: CO\ :sub:`2`
fail1> .. |FFCO2| replace:: FFCO\ :sub:`2`

to show (when rendered, e.g., by `restview`) "FFCO2"

* the first time in italic, the second time not
* both times with '2' subscripted
* neither times with the '|' showing

The above fragment fails, as

- only the second "FFCO2" is subscripted
- the first "FFCO2" both shows the pipes and does not subscript

I also tried

fail2> Cities produce more than 70% of global fossil-fuel |CO2| emissions (|iFFCO2|). We have cutting-edge science relating how cities and regions settle and use their land (LULC) to their FFCO2 emissions.

fail2> .. |CO2| replace:: CO\ :sub:`2`
fail2> .. |FFCO2| replace:: FFCO\ :sub:`2`
fail2> .. |iFFCO2| replace:: *|FFCO2|*

which produces identical (failed results). Thanks to FAQ section 2.16[1] I learned I could do the following, which works:

works> Cities produce more than 70% of global fossil-fuel |CO2| emissions (|iFFCO2|). We have cutting-edge science relating how cities and regions settle and use their land (*LULC*) to their |FFCO2| emissions.

works> .. |CO2| replace:: CO\ :sub:`2`
works> .. |FFCO2| replace:: FFCO\ :sub:`2`
works> .. |iFFCO2| raw:: html
works>
works>    <em>FFCO<sub>2</sub></em>

but I'd prefer to do this (and similar simple styling of replacements) without `raw` directives. Is that currently possible?

If possible please reply to me (directly) as well as the list, and
TIA, Tom Roche <Tom...@po...>
