textproc/jless: update to 0.9.0
v0.9.0 (2023-07-16)
==================
New features:
- A new command `ys` will copy unescaped string literals to the
clipboard. Control characters remain escaped.
- The length of Arrays and size of Objects is now shown before the
container previews, e.g., (`foo: (3) ["apple", "banana", \
"cherry"]`)
- Add a new family of "print" commands, that nearly map to the existing
copy commands, that will simply print a value to the screen. This is
useful for viewing the entirety of long string values all at once, or
if the clipboard functionality is not working; mouse-tracking will be
temporarily disabled, allowing you to use your terminal's native
clipboard capabilities to select and copy the desired text.
- Support showing line numbers, both absolute and/or relative. Absolute
line numbers refer to what line number a given node would appear on if
the document were pretty printed. This means there are discontinuities
when in data mode because closing brackets and braces aren't
displayed. Relative line numbers show how far a line is relative to
the currently focused line. The behavior of the various combinations
of these settings matches vim: when using just relative line numbers
alone, the focused line will show `0`, but when both flags are enabled
the focused line will show its absolute line number.
- Absolute line numbers are enabled by default, but not relative line
numbers. These can be enabled/disabled/re-enabled via command line
flags `--line-numbers`, `--no-line-numbers`,
`--relative-line-numbers` and `--no-relative-line-numbers`, or via
the short flags `-n`, `-N`, `-r`, and `-R` respectively.
- These settings can also be modified while jless is running. Entering
`:set number`/`:set relativenumber` will enable these settings,
`:set nonumber`/`:set norelativenumber` will disable them, and
`:set number!`/`:set relativenumber!` will toggle them, matching
vim's behavior.
- There is not yet support for a jless config file, so if you would
like relative line numbers by default, it is recommended to set up
an alias: `alias jless=jless --line-numbers --relative-line-numbers`.
- You can jump to an exact line number using `<count>g` or `<count>G`.
When using `<count>g` (lowercase 'g'), if the desired line number is
hidden inside of a collapsed container, the last visible line number
before the desired one will be focused. When using `<count>G`
(uppercase 'G'), all the ancestors of the desired line will be
expanded to ensure it is visible.
- Add `C` and `E` commands, analagous to the existing `c` and `e`
commands, to deeply collapse/expand a node and all its siblings.
Improvements:
- In data mode, when a array element is focused, the highlighting on the
index label (e.g., "[8]") is now inverted. Additionally, a '▶' is
always displayed next to the currently focused line, even if the
focused node is a primitive. Together these changes should make it
more clear which line is focused, especially when the terminal's
current style doesn't support dimming (`ESC [ 2 m`).
- When using the `c` and `e` commands (and the new `C` and `E`
commands), the focused row will stay at the same spot on the screen.
(Previously jless would try to keep the same row visible at the top of
the screen, which didn't make sense.)
Bug fixes:
- Scrolling with the mouse will now move the viewing window, rather than
the cursor.
- When searching, jless will do a better job jumping to the first match
after the cursor; previously if a user started a search while focused
on the opening of a Object or Array, any matches inside that container
were initially skipped over.
- When jumping to a search match that is inside a collapsed container,
search matches will continue to be highlighted after expanding the
container.
- [Issue #71 / PR #98]: jless will return a non-zero exit code if it
fails to parse the input.
Other notes:
- The minimum supported Rust version has been updated to 1.67.
- jless now re-renders the screen by emitting "clear line" escape codes
(`ESC [ 2 K`) for each line, instead of a single "clear screen" escape
code (`ESC [ 2 J`), in the hopes of reducing flicking when scrolling.

textproc/jless: update to 0.8.0
This new release of jless ships with two major new features: basic YAML support
and copying to clipboard!
jless will now check the file extension of the input file, and automatically
parse .yml and .yaml files as YAML and use the same viewer as for JSON data.
Alternatively passing in a --yaml flag will force jless to parse the input as
YAML and can be used when reading in YAML data from stdin.
(alias yless="jless --yaml" perhaps?) YAML aliases are automatically \
expanded,
but their corresponding anchors are not visible, nor are comments. YAML supports
non-string keys, and even non-scalar keys in mappings (e.g., the key of map can
be an array with multiple elements). Non-string keys are shown with square
brackets, e.g., [true]: "value", instead of quotes. Non-scalar keys \
are handled
on the screen and displayed properly, but you cannot expand and collapse their
individual elements.
While navigating data, jless also now supports copying various items to your
system clipboard.
yy will copy the value of the currently focused node, pretty printed
yv will copy the value of the currently focused node in a "nicely" \
printed
one-line format
yk will copy the key of the current key/value pair
yp will copy the path from the root JSON element to the currently focused
node, e.g., .foo[3].bar
yb functions like yp, but always uses the bracket form for object keys,
e.g., ["foo"][3]["bar"], which is useful if the \
environment where you'll
paste the path doesn't support the .key format, like in Python
yq will copy a jq style path that will select the currently focused node,
e.g., .foo[].bar
This release also includes a couple of new movement commands, and some stability
fixes. The full list of changes can be seen below.
Full list of changes
New features:
Support displaying YAML files with autodetection via file extension, or
explicit --yaml or --json flags.
Support copying values (with yy or yv), object keys (with yk), and paths to
the currently focused node (with yp, yb or yq).
Implement ctrl-u and ctrl-d commands to jump up and down by half the
screen's height, or by a specified number of lines.
Implement ctrl-b and ctrl-f commands for scrolling up and down by the height
of the screen. (Aliases for PageUp and PageDown)
Improvements:
Keep focused line in same place on screen when toggling between line and
data modes; fix a crash when focused on a closing delimiter and switching to
data mode.
Pressing Escape will clear the input buffer and stop highlighting search
matches.
Bug Fixes:
Ignore clicks on the status bar or below rather than focusing on hidden
lines, and don't re-render the screen, allowing the path in the status bar
to be highlighted and copied.
Issue #61: Display error message for unrecognized CSI escape sequences and
other IO errors instead of panicking.
Issue #62: Fix broken window resizing / SIGWINCH detection caused by
clashing signal handler registered by rustyline.
PR #54: Fix panic when using Ctrl-C or Ctrl-D to cancel entering search
input.
Other Notes:
Upgraded regex crate to 1.5.5 due to CVE-2022-24713. jless accepts and
compiles untrusted input as regexes, but you'd only DDOS yourself, so it's
not terribly threatening vulnerability.
