A very long-awaited improvement: for unicode exceptions, and I/O
exceptions which look like they were caused by a unicode error
(usually text decoding failure), our error message now includes
an explanation and advice on what to do.
Currently this uses the GHC.IO.Encoding API, which is not ideal:
"The API of this module is unstable and not meant to be consumed by
the general public. If you absolutely must depend on it, make sure to
use a tight upper bound, e.g., base < 4.X rather than base < 5,
because the interface can change rapidly without much warning."
Also it relies on scanning for patterns in GHC's various
unicode-related error messages, which may not be complete and could
change in future. To do: try the encoding package's IO helpers,
perhaps they give more specific exceptions.
- Added support for unseparated dates, for convenience in ghci and for parseHledgerVersion
- Noted two user-facing uses: --value's argument, and import's .latest files.
YYYYMMDD dates will now also work there. Left this undocumented.
- Noted this is now more permissive, parsing many integers successfully; not expecting problems.
These now call error' and show errors in the standard style:
- reading a nonexistent data file
- reading an unsafe dotted file name on windows
- web: using --socket on windows
- demo: demo not found
- demo: error while running asciinema
- diff: bad arguments
- print --match: no match found
- register --match: no match found
- roi: no investment transactions found
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.
We now support having multiple sessions clocked in. These are paired by
account name if given on the out entry, and otherwise an out closes the
most recent in entry.
Note that this breaks some backwards compatibility, in that we
previously ignored the description on the clock out entry. To mitigate
this, a new hidden flag --timeclock-old has been added, which reverts to
the old behavior.
Previously our cabal files used cabal-version 1.12, and were in theory
buildable with any ancient version of cabal. Now at least cabal 2.2
(or a version of stack built with with similar Cabal version) is
required to build hledger.
"-" implies data from standard input so "string" is perhaps more
correct, but I think this is a harmless simplification and it
makes `files` output consistent when run by `run`.
`If blocks` and `If tables` now allow multiple matchers on the same line
separated by `&&` (AND) or `&& !` (AND NOT).
Example `if block` with two matchers on the same line:
if %description amazon && %date 2025-02-22
account2 expenses:books
Example `if table` with two matchers on the same line:
if,account2
%description amazon && %date 2025-02-22, expenses:books
On some systems, TERM is set to a value that doesn't have a valid
terminfo entry. Rather than hackily fall back on a value for TERM that
appears to work in most contexts (TERM=dumb) but which isn't guaranteed
anywhere to be valid, use proper POSIX ioctls to get the tty width.
This has the added bonus of also working on Windows.
In fact, we already settled on computing the terminal size in this way
in hledger-lib, so this commit centralizes the choice of the logic
there.
Also added a note for alternative methods and their tradeoffs, in case
this turns out to be fragile on some systems.
When running `cd hledger-lib && ghci test/unittest.hs`, ghci complains
with:
```
test/unittest.hs:7:1: error:
Could not find module ‘Hledger’
It is not a module in the current program, or in any known package.
|
7 | import "hledger-lib" Hledger (tests_Hledger)
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Failed, no modules loaded.
```
This commit removes the "hledger-lib" package-qualified import, such
that above ghci command works as expected.
However, there is a comment in hledger-lib/test/unittest.hs that says:
> package-qualified import to avoid cabal missing-home-modules warning
> (and double-building ?)
The missing-home-modules warning and the double building can indeed be
reproduced by running (after removing the "hledger-lib"
package-qualified import): `cd hledger-lib && cabal build unittest`. It
will first build `hledger-lib`, then show a warning about
missing-home-modules, and then build `hledger-lib` again.
After comparing the unittest sections of hledger.cabal and
hledger-lib.cabal, the solution turned out to be to remove `./` from
hs-source-dirs for unittest. Don't ask me why though!
Overall it's a nice cleanup.
Previously, hledger could read CSV files containing non-ascii
characters only if they are UTF8-encoded. Now there is a new CSV
rule, encoding ENCODING, which allows reading CSV files with other
encodings.
This adds a dependency on the encoding library, which supports fewer
encodings than text-icu but does not require a third-party C library.
To avoid build issues on various platforms, we require version 0.10+.
This adds some use of the ImplicitParams language extension, required
by encoding's API, but only in a small code region.
This also changes the type of Reader's rReadFn; it now takes
a `Handle` rather than a `Text`, allowing more flexibility.
