* doc/misc/flymake.texi: Fix typos. Downcase the first word of
each index entry, for more reliable sorting.
(Starting Flymake, Finding diagnostics, Troubleshooting): Fix
typos.
bug#50244
* doc/misc/flymake.texi (Starting Flymake): New section.
(Finding diagnostics): New section, now contains info previously in
"Listing diagnostics"
(Mode line status): Renamed from "Mode-line syntax check status"
(Troubleshooting): Renamed from "Backend exceptions".
(Flymake error types): Tweak phrasing.
This is done with two new concepts: "foreign diagnostics" and
"list-only diagnostics". The manual has been updated with a
description of these new concepts.
* doc/misc/flymake.texi (Flymake utility functions):
Explain creation of foreign diagnostics.
(Foreign and list-only diagnostics): New subsection.
(Listing diagnostics): New subsection.
* lisp/progmodes/flymake.el
(Version): Bump to 1.2.1
(project): Require project.
(flymake--diag): Add new slots 'orig-beg' and 'orig-end'. Rename
'buffer' slot to 'locus'.

* lisp/progmodes/flymake.el (flymake-mode-line-indicator-format):
New variable (bug#33740).
(flymake--mode-line-format): Use it.
The typical use of this function (which is parsing compiler diagnostic
messages), lends itself too easily to one the problems in bug#29193.
Make it a friendlier API.

Eglot, a third-party package which uses Flymake, has its own
diagnostic types such as 'eglot-error', 'eglot-warning', etc... While
not being too long, they will not fit in the type column of the "list
all diagnostics" buffer. This commit allows diagnostic types to have
user-defined names and also assigns names to the default categories.
* doc/misc/flymake.texi (Flymake error types): Describe
flymake-type-name prop.
* lisp/progmodes/flymake.el (flymake--diagnostics-buffer-entries):
Use type names.
(flymake-error, flymake-warning, flymake-note): Give these
diagnostic categories default type names.
Problem was reintroduced by commit titled:
"Mention use of C-h . (display-local-help) in Flymake manual"
* doc/misc/flymake.texi: Don't @include a relative path.
That varaiable was an association between symbols and properties,
effecively duplicating symbol's property lists. It is simpler to just
put properties on symbols. Backward compatibility to the old variable
has been kept.

`flymake-bitmap', not `bitmap' in these symbols.
(flymake--lookup-type-property, flymake--highlight-line): Rewrite.
Honor flymake-diagnostic-types-alist for backward
compatibility.

Flymake backends that rely on sentinels running asynchronously and
checking buffer-local variables that hold running processes should
check for obsoleteness in the correct buffers, otherwise a (harmless)
warning might be triggered.

Check buffer-local proc in the current buffer.
* lisp/progmodes/elisp-mode.el (elisp-flymake-byte-compile):
Check buffer-local proc in the current buffer.
Fix some confusing parts of Flymake user documentation, like a
repeated listing of situations leading to a syntax check.
Documentation is now divided into three chapters only: "Using
Flymake", "Extending Flymake", and a chapter for the legacy backend.
Obsolete mention of "errors" and "lines" is replaced by
"diagnostics/problems" and "regions" where appropriate.

The first of these problems is longstanding: if an error-less B.h is
included from error-ridden A.h, flymake's legacy parser will panic
(and disable itself) since it sees a non-zero exit for a clean file.
To fix this, recommend returning 'true' in the documentation for the
check-syntax target.
Another problem was introduced by the parser rewrite. For error
patterns spanning more than one line, point may be left in the middle
of a line and thus render other patterns useless. Those patterns were
written for the old line-by-line parser. To make them useful again,
move to the beginning of line in those situations.
The third problem was also longstanding and happened on newer GCC's:
The "In file included from" prefix confused
flymake-proc-get-real-file-name. Fix this.
Also updated flymake--diag-region to fallback to highlighting a full
line less often.
Add automatic tests to check this.
* lisp/progmodes/flymake-proc.el
