# `derivepassphrase` wish conventional-configurable-text-styling ???+ wish "Wish details: `derivepassphrase vault` should support conventional and configurable text styling" <table id="bug-summary" markdown> <tr><th scope=col>Class<td><i>wish</i><td>This is a request for an enhancement. <tr><th scope=col>Priority<td><i>low</i><td>We aren't sure whether to fix this or not. <tr><th scope=col>Difficulty<td><i>taxing</i><td>Needs external things we don't have (standards, users etc). <tr><th scope=col>Present-in<td colspan=2><b>0.5</b> 0.5.1 0.5.2 </table> `derivepassphrase` intends to support text styling (color, boldface) for warning and error messages (and possibly for other future uses) for TTY devices. **The question is, how exactly? The conventions in this regard are still in flux.** * Color usage is generally tri-state: `--color=always|auto|never` (GNU `grep` et al.) or `--color=yes|no|auto` (pytest). Which terminology should be used? * For color usage, we should support the `NO_COLOR` and `FORCE_COLOR` environment variables to override the auto-detected result. Which variable should take precedence, `NO_COLOR` or `FORCE_COLOR`? (The `FORCE_COLOR` FAQ site gives `FORCE_COLOR` precedence over `NO_COLOR`, Python 3.13 gives `NO_COLOR` precedence.) * Should text decorations and text styling (bold, underline) be treated equivalently to color? Should this be handled by the same "color" options, or do we need separate "styling" options? * Should we support the [`TTY_COMPATIBLE=1|0|<unset>` variable as proposed by Rich](https://github.com/Textualize/rich/issues/2924#issuecomment-2757673602)? * * * These conventions must stabilize first. <b>Until then</b>, as a baseline, `derivepassphrase` shall emit device-independent output without color or text styling, in adherence to [Eric S. Raymond's Rule of Composition](http://www.catb.org/~esr/writings/taoup/html/ch01s06.html#id2877684). (Baseline implemented in [64b076508d85bc24a28e253d081b4f2bf95b552c](https://git.schokokeks.org/derivepassphrase.git/commit/64b076508d85bc24a28e253d081b4f2bf95b552c).)
