# Changelog
2
+
3
+
## v1.3.0 (2025-05-26)
4
+
- feat: add `--choose-dir` arg
5
+
- feat: add `--entry-dir=PATH` arg
6
+
7
+
## v1.2.0 (2025-05-26)
8
+
- feat(images): Cache images to avoid unecessary re-processing
9
+
10
+
## v1.1.0 (2025-05-21)
11
+
- fix(images): Improve performance by only locking critical parts of image loading
12
+
- fix(images): Thread the image loading process as not to block user input
13
+
14
+
## v1.0.1 (2025-04-14)
15
+
- fix(errors): Ensure logged enums are wrapped in `@tagName()` for readability.
16
+
17
+
## v1.0.0 (2025-04-06)
18
+
- New Keybinds:
19
+
- Added ability to copy files.
20
+
This is done by (y)anking the file, then (p)asting in the desired directory.
21
+
This action can be (u)ndone and behind the scenes is a deletion.
22
+
Currently this feature only supports files, folders, and symlinks.
23
+
- Added force delete keybind. It's unbound by default.
24
+
- Added keybind `v` to view additional information about the selected entry.
25
+
- A huge audit of `try` usages was conducted. As a result of this, Jido is much
26
+
more resiliant to errors and should crash less often in known cases.
27
+
- Added `:h` command to view help / keybind menu.
28
+
- Added config option `true_dir_size` to see the true size of directories.
29
+
- Added [-v | --version] and [-h | --help] args.
30
+
- File permissions are now displayed in the file information bar to the bottom
31
+
of Jido.
32
+
- Keybinds can now be unbound. Some keybinds are now unbound by default.
33
+
See [Configuration](https://github.com/BrookJeynes/jido?tab=readme-ov-file#configuration)
34
+
for more information.
35
+
- Fixes:
36
+
- fix: Scrolling command history now provides the correct values.
37
+
- fix: Ensure complete Git branch is displayed. Previously if the branch
38
+
contained slashes, it would only retrieve the ending split.
39
+
- fix: Allow the cursor to be moved left and right on text input.
40
+
- fix: The keybind " " (spacebar) is now accepted by the config.
41
+
- fix: Multi-char keybinds now throw errors instead of crashing.
42
+
- fix: Undoing a delete/rename wont overwrite an item with the same name now.
43
+
44
+
## v0.9.9 (2025-04-06)
45
+
- feat: Added ability to copy folders.
46
+
- fix: Scrolling command history now provides the correct values.
47
+
48
+
## v0.9.8 (2025-04-04)
49
+
- fix: Ensure complete Git branch is displayed.
50
+
- refactor: Audit try usage to improve system resiliance.
51
+
- refactor: Removed need for enum based notifications.
52
+
53
+
## v0.9.7 (2025-04-01)
54
+
- feat: Added ability to copy files.
55
+
This is done by (y)anking the file, then (p)asting in the desired directory.
56
+
This action can be (u)ndone and behind the scenes is a deletion.
57
+
- fix: Allow the cursor to be moved left and right.
58
+
- refactor: Changed action struct field names to be more clear.
59
+
- refactor: Better ergonomics around writing to the log file.
60
+
61
+
## v0.9.6 (2025-03-31)
62
+
- feat: Added ability to unbound keybinds.
63
+
- feat: Added force delete keybind. It's unbound by default.
64
+
65
+
## v0.9.5 (2025-03-29)
66
+
- feat: Added [-v | --version] and [-h | --help] args.
67
+
68
+
## v0.9.4 (2025-03-29)
69
+
- feat: Added keybind `h` to view help / keybind menu.
70
+
- refactor: `List` drawing logic is now handled by the `Drawer{}`.
71
+
72
+
## v0.9.3 (2025-03-27)
73
+
- feat: The keybind " " is now accepted. This allows spacebar to be bound.
74
+
- feat: Duplicate keybind notification now includes additional information.
75
+
- fix: Multi-char keybinds now throw errors instead of crashing.
76
+
- fix: Remove need to init notification handler. This fixes many issues with
77
+
the places in the code notifications could be produced.
78
+
79
+
## v0.9.2 (2025-03-25)
80
+
- feat: Added keybind `v` to view additional information about the selected entry.
81
+
- feat: Added config option `true_dir_size` to see the true size of directories.
82
+
- fix: Undoing a delete/rename wont overwrite an item with the same name now.
83
+
84
+
## v0.9.1 (2025-03-23)
85
+
- feat: File permissions are now displayed in the file information bar to the
86
+
bottom of Jido.
87
+
88
+
## v0.9.0 (2025-03-21)
89
+
- New Keybinds:
90
+
- Added keybind `<CTRL-r>` to reload config while Jido is running.
91
+
- Added keybind `.` to hide/show hidden files at runtime.
92
+
Default behaviour is still read from the config file if set.
93
+
- Added keybind rebinding.
94
+
Jido now allows you to rebind certain keys. These can be rebound via the config
95
+
file. See [Configuration](https://github.com/BrookJeynes/jido?tab=readme-ov-file#configuration)
96
+
for more information.
97
+
- Added file logger.
98
+
This file logger allows Jido to provide users with more detailed log messages
99
+
the notification system cannot. The log file can be found within the config
100
+
directory under the file `log.txt`.
101
+
- Jido is now built with the latest stable version of Zig, v0.14.0.
102
+
- Fixes:
103
+
- Hiding/showing hidden files after cd would cause all the files to visually
104
+
disappear.
105
+
- Off by one error when traversing command history causing the list to skip
106
+
some entries.
107
+
- Empty commands are no longer added to the command history. This now means
108
+
commands are whitespace trimmed.
109
+
- Move logic to hide dot files from renderer to directory reader.
110
+
This moves the logic to hide dot files out from the renderer to the
111
+
directory reader. This means if hidden files are turned off, they aren't
112
+
even stored.
113
+
- Default styling didn't specify styling for notification box text. This
114
+
would cause visual issues for light mode users.
115
+
116
+
## v0.8.3 (2025-03-19)
117
+
- feat: Added keybind `<CTRL-r>` to reload config while Jido is running.
118
+
- fix: Hiding/showing hidden files after cd would display no files.
119
+
- fix: Off by one error when traversing command history...
120
+
- fix: Dont add empty commands to command history.
121
+
- docs: Updated readme to mention new keybind.
122
+
- docs: Reordered keybinds section to add "Global" section.
123
+
124
+
## v0.8.2 (2025-03-18)
125
+
- fix: Move logic to hide dot files from renderer to directory reader.
126
+
this moves the logic to hide dot files out from the renderer to the
127
+
directory reader. This means if hidden files are turned off, they aren't
128
+
even stored.
129
+
- feat: Added keybind `.` to hide/show hidden files at runtime.
130
+
Default behaviour is still read from the config file if set.
131
+
132
+
## v0.8.1 (2025-03-11)
133
+
- feat: Jido is now built with zig 0.14.0.
134
+
- chore: Update packages.
135
+
136
+
## v0.8.0 (2025-01-07)
137
+
- Rebrand from zfe to Jido by @BrookJeynes in #16
138
+
I felt that I wanted this project to have more of its own identity so I
139
+
decided now that this project is getting closer to a v1.0 release, it's time
140
+
to give it a proper name.
141
+
- Added command mode by @BrookJeynes in #14
142
+
Command mode is a way for users to enter Jido commands.
143
+
Currently supported commands:
144
+
```
145
+
Command mode:
146
+
:q :Exit.
147
+
:config :Navigate to config directory if it exists.
148
+
:trash :Navigate to trash directory if it exists.
149
+
:empty_trash :Empty trash if it exists. This action cannot be undone.
150
+
```
151
+
- Deletes are now sent to `<config>/trash` instead of `/tmp`. by @BrookJeynes in #15
152
+
Previously, deletes were sent to `/tmp`. This made it convenient for cleanup
153
+
however caused issues on certain distros. This was because the `/tmp` dir was
154
+
on a separate mount point and therefore the file was unable to be moved there.
155
+
Tying into this, there is now a new `empty_trash_on_exit` config option set to
156
+
false by default.
157
+
- Reworked the notification stylings. Notification stylings are now under the
158
+
notification namespace within the config file.
159
+
- The code used to detect the git branch no longer needs git installed on the
160
+
system.
161
+
- Displayed file size now shows the correct file size for files.
162
+
163
+
## v0.7.0 (2025-01-01)
164
+
- Fix notification segfaults by @BrookJeynes in #9
165
+
- Conform codebase styling by @BrookJeynes in #10
166
+
- Create release action by @BrookJeynes in #11
167
+
- Separate event and draw logic by @BrookJeynes in #12
168
+
- Updated config location from `$HOME/.config/zfe` to `$HOME/.zfe` by @BrookJeynes in 3cb9bb2
169
+
- This means that the config can be found at either `$HOME/.zfe/` or
170
+
`$XDG_CONFIG_HOME/zfe/config/`. The old path will continue to work for
171
+
the meantime but has been deprecated.
172
+
- Show git branch when available by @BrookJeynes in #13
173
+
174
+
## v0.6.1 (2024-12-03)
175
+
- Updated libvaxis and refactored build.zig by @BrookJeynes in #7
176
+
- Notifications are now their own windows that appear to the right by @BrookJeynes in #8
177
+
- Notifications are now their own windows that appear to the right of the
178
+
screen. they disappear after 3 seconds but note that renders only occur
179
+
after an action has been polled. this means that if you wait for 3 seconds
180
+
without an action, the notification wont disappear until an action occurs.
181
+
- Added info notifications on actions such as renaming, deleting, changing
182
+
dir, etc.
183
+
- Added notification_box colour setting to config.
184
+
185
+
## v0.5.0 (2024-06-05)
186
+
- Updated libvaxis dependency.
187
+
- Fixed an issue where viewing a PDF would freeze zfe. This fixes issue #5
188
+
- Added additional "Optional Dependencies" section to README to specify optional
189
+
dependencies for zfe (such as pdftotext for PDF viewing).
190
+
- Updated the way images are streamed in. This should help with #4 but I don't
191
+
think it ultimately fixes the issue at hand.
192
+
193
+
## v0.4.0 (2024-06-05)
194
+
- Fixed bug where cursor would jump back to the top after deleting, renaming,
195
+
creating, or undoing.
196
+
- Added new keybind `c` to change directory via path.
197
+
- Previous positions are saved when entering a new directory.
198
+
- PDFs can now be read if `pdftotext` is installed.
199
+
- Undo history can now only store the last 100 events.
200
+
- List scrolling is now squeaky smooth.
201
+
- Other general refactors and bug fixes.
202
+
203
+
## v0.3.0 (2024-05-30)
204
+
- Moved render and event handling logic to their own functions. This will make
205
+
it a more pleasant experience for contributors.
206
+
- Added issue templates for easier and more concise bug reports and feature
207
+
requests.
208
+
- Fixed issue where images would stop rendering if an event was emitted without
209
+
changing selected item.
210
+
- Implemented ability to delete files and folders.
211
+
- Implemented ability to rename files and folders.
212
+
- Implemented ability to undo deletions and renames within a session.
213
+
- Implemented ability to create folders and directories.
214
+
- Updated README with new keybinds.
215
+
- Added config option for styling info bar.
216
+
217
+
## v0.2.0 (2024-05-26)
218
+
- Implemented fuzzy search for items in a directory.
219
+
- Files can now be opened with `$EDITOR`.
220
+
- Error messages now displayed in app.
221
+
- Better errors when failing to read config.
222
+
- Stopped supporting Windows.
223
+
224
+
## v0.1.1 (2024-05-25)
225
+
- Added better error handling.
226
+
- Added new config style for error bar.
227
+
- Updated README to include config schema.

## Configuration
25
-
Configure `zfe` by editing the external configuration file located at either:
26
-
- `$HOME/.zfe/config.json`
27
-
- `$XDG_CONFIG_HOME/zfe/config.json`.
76
+
Configure `jido` by editing the external configuration file located at either:
77
+
- `$HOME/.jido/config.json`
78
+
- `$XDG_CONFIG_HOME/jido/config.json`.
28
79
29
-
An example config file can be found [here](https://github.com/BrookJeynes/zfe/blob/main/example-config.json).
80
+
Jido will look for these env variables specifically. If they are not set, Jido
81
+
will not be able to find the config file.
