Hledger.Utils.IO helpers have been updated and new ones have been
added (exitOnExceptions, exitWithError) to allow consistent display of
program errors whether compiled with GHC <9.10, GHC 9.10, or GHC >9.10.
The trailing newlines added by GHC 9.10 are gone,
and so is the "uncaught exception" output added by GHC 9.12.
Builds made with ghc 9.10+ and the 'debug' build flag, will show
(some kind of, partial) stack traces when the program ends with an
error. (And also will have ghc-debug support enabled.)
The stack traces will probably improve in due course.
--color now also works in a config file, like --pager, except for two
cases: it does not affect colouring of debug output, or the colouring
helpers used in the check recentassertions error message.
When built with the ghcdebug flag and started with --debug=-1 (or -2
to pause at startup, or -3 to pause before exit), hledger can be
controlled by ghc-debug clients like ghc-debug-brick or a custom
ghc-debug query script.
Also, refactor version string code.
Introduced or bumped dependencies:
- brick-2.1.1
- vty-6.1
- vty-crossplatform-0.4.0.0
- vty-windows-0.2.0.1 conditionally on windows (current version of
vty-crossplatform has 0.2.0.0 as a lower bound, need to put a newer version explcitly;
once we get a newer vty-crossplatform, we will be able to drop this conditional)
- vty-unix (indirectly via vty-crossplatform)
Hledger.Utils.Debug's "trace or log" functions are now controlled as
follows: to enable logging, append ",logging" to the program name at
startup (using withProgName). This also works when running in GHCI.
And they log to PROGNAME.log, not debug.log.
All (hopefully) debug logging in the hledger packages is now "trace or
log" capable.
This means that hledger-ui should now log all debug output to
./hledger-ui.log, with none of it appearing on the console.
Follow-on from the brick 1.0 migration work (#1889, #1919).
These new types aim to be more restrictive, allowing fewer invalid
states, and easier to inspect and debug. The screen types store only
state, not behaviour (functions), and there is no longer a circular
dependency between UIState and Screen.
