Previously, tags were associated to terminal styles, which doesn't make
sense on terminal-free pretty printing scenarios.
This commit moves tag interpretation to the toplevel terminal handling
module `Topfmt`.
|
|
For legacy reasons, pretty printing required to provide a "tag"
interpretation function `pp_tag`. However such function was not of much
use as the backends (richpp and terminal) hooked at the `Format.tag`
level.
We thus remove this unused indirection layer and annotate expressions
with their `Format` tags.
This is a step towards moving the last bit of terminal code out of the
core system.
|
|
This is what has always been used, so it doesn't represent a functional
change.
This is just a preliminary patch, but many more possibilities could be
done wrt tags.
|
|
We use the same printing path for color and mono terminal output, thus
removing the duplicate printers which avoids problems as they don't have
to be kept in sync anymore.
We tag unconditionally but set the `pp_tag` tagger properly. This
removes IO from `Ppstyle` with IMO is the right thing to do.
Test suite passes.

On the user side, coqtop and coqc take a list of warning names or categories
after -w. No prefix means activate the warning, a "-" prefix means deactivate
it, and "+" means turn the warning into an error. Special categories include
"all", and "default" which contains the warnings enabled by default.
We also provide a vernacular Set Warnings which takes the same flags as argument.
Note that coqc now prints warnings.
The name and category of a warning are printed with the warning itself.
On the developer side, Feedback.msg_warning is still accessible, but the
recommended way to print a warning is in two steps:
1) create it by:
let warn_my_warning =
CWarnings.create ~name:"my-warning" ~category:"my-category"
(fun args -> Pp.strbrk ...)
2) print it by:
warn_my_warning args

This patch splits pretty printing representation from IO operations.
- `Pp` is kept in charge of the abstract pretty printing representation.
- The `Feedback` module provides interface for doing printing IO.
The patch continues work initiated for 8.5 and has the following effects:
- The following functions in `Pp`: `pp`, `ppnl`, `pperr`, `pperrnl`,
`pperr_flush`, `pp_flush`, `flush_all`, `msg`, `msgnl`, `msgerr`,
`msgerrnl`, `message` are removed. `Feedback.msg_*` functions must be
used instead.
- Feedback provides different backends to handle output, currently,
`stdout`, `emacs` and CoqIDE backends are provided.
- Clients cannot specify flush policy anymore, thus `pp_flush` et al are
gone.
- `Feedback.feedback` takes an `edit_or_state_id` instead of the old
mix.
Lightly tested: Test-suite passes, Proof General and CoqIDE seem to work.

This allows fatal_error to be used for printing anomalies at loading time.
