TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
7
+
8
+
1. Definitions.
9
+
10
+

+
other entities that control, are controlled by, or are under common

+
direction or management of such entity, whether by contract or
21
+
otherwise, or (ii) ownership of fifty percent (50%) or more of the
22
+

23
+
24
+
"You" (or "Your") shall mean an individual or Legal Entity
25
+
exercising permissions granted by this License.
26
+
27

29
+
source, and configuration files.
30
+
31
+
"Object" form shall mean any form resulting from mechanical
32
+
transformation or translation of a Source form, including but
33
+
not limited to compiled object code, generated documentation,
34
+
and conversions to other media types.
35
+
36
+
"Work" shall mean the work of authorship, whether in Source or
37
+
Object form, made available under the License, as indicated by a
38
+
copyright notice that is included in or attached to the work
39
+
(an example is provided in the Appendix below).
40
+
41
+
"Derivative Works" shall mean any work, whether in Source or Object
42
+
form, that is based on (or derived from) the Work and for which the
43
+
editorial revisions, annotations, elaborations, or other modifications
44
+
represent, as a whole, an original work of authorship. For the purposes
45
+
of this License, Derivative Works shall not include works that remain
46
+
separable from, or merely link (or bind by name) to the interfaces of,
47
+
the Work and Derivative Works thereof.
48
+
49
+
"Contribution" shall mean any work of authorship, including
50
+
the original version of the Work and any modifications or additions
51
+
to that Work or Derivative Works thereof, that is intentionally
52
+
submitted to Licensor for inclusion in the Work by the copyright owner
53
+
or by an individual or Legal Entity authorized to submit on behalf of
54
+
the copyright owner. For the purposes of this definition, "submitted"
55
+
means any form of electronic, verbal, or written communication sent
56
+
to the Licensor or its representatives, including but not limited to
57
+
communication on electronic mailing lists, source code control systems,
58
+
and issue tracking systems that are managed by, or on behalf of, the
59
+
Licensor for the purpose of discussing and improving the Work, but
60
+
excluding communication that is conspicuously marked or otherwise
61
+
designated in writing by the copyright owner as "Not a Contribution."
62
+
63
+
"Contributor" shall mean Licensor and any individual or Legal Entity
64
+
on behalf of whom a Contribution has been received by Licensor and
65
+
subsequently incorporated within the Work.
66
+
67
+
2. Grant of Copyright License. Subject to the terms and conditions of
68
+
this License, each Contributor hereby grants to You a perpetual,
69
+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
70
+
copyright license to reproduce, prepare Derivative Works of,
71
+
publicly display, publicly perform, sublicense, and distribute the
72
+
Work and such Derivative Works in Source or Object form.
73
+
74
+
3. Grant of Patent License. Subject to the terms and conditions of
75
+
this License, each Contributor hereby grants to You a perpetual,
76
+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
77
+
(except as stated in this section) patent license to make, have made,
78
+
use, offer to sell, sell, import, and otherwise transfer the Work,
79
+
where such license applies only to those patent claims licensable
80
+
by such Contributor that are necessarily infringed by their
81
+
Contribution(s) alone or by combination of their Contribution(s)
82
+
with the Work to which such Contribution(s) was submitted. If You
83
+
institute patent litigation against any entity (including a
84
+
cross-claim or counterclaim in a lawsuit) alleging that the Work
85
+
or a Contribution incorporated within the Work constitutes direct
86
+
or contributory patent infringement, then any patent licenses
87
+
granted to You under this License for that Work shall terminate
88
+
as of the date such litigation is filed.
89
+
90
+
4. Redistribution. You may reproduce and distribute copies of the
91
+
Work or Derivative Works thereof in any medium, with or without
92
+
modifications, and in Source or Object form, provided that You
93
+
meet the following conditions:
94
+
95
+
(a) You must give any other recipients of the Work or
96
+
Derivative Works a copy of this License; and
97
+
98
+
(b) You must cause any modified files to carry prominent notices
99
+
stating that You changed the files; and
100
+
101
+
(c) You must retain, in the Source form of any Derivative Works
102
+
that You distribute, all copyright, patent, trademark, and
103
+
attribution notices from the Source form of the Work,
104
+
excluding those notices that do not pertain to any part of
105
+
the Derivative Works; and
106
+
107
+
(d) If the Work includes a "NOTICE" text file as part of its
108
+
distribution, then any Derivative Works that You distribute must
109
+
include a readable copy of the attribution notices contained
110
+
within such NOTICE file, excluding those notices that do not
111
+
pertain to any part of the Derivative Works, in at least one
112
+
of the following places: within a NOTICE text file distributed
113
+
as part of the Derivative Works; within the Source form or
114
+
documentation, if provided along with the Derivative Works; or,
115
+
within a display generated by the Derivative Works, if and
116
+
wherever such third-party notices normally appear. The contents
117
+
of the NOTICE file are for informational purposes only and
118
+
do not modify the License. You may add Your own attribution
119
+
notices within Derivative Works that You distribute, alongside
120
+
or as an addendum to the NOTICE text from the Work, provided
121
+
that such additional attribution notices cannot be construed
122
+
as modifying the License.
123
+
124
+
You may add Your own copyright statement to Your modifications and
125
+
may provide additional or different license terms and conditions
126
+
for use, reproduction, or distribution of Your modifications, or
127
+
for any such Derivative Works as a whole, provided Your use,
128
+
reproduction, and distribution of the Work otherwise complies with
129
+
the conditions stated in this License.
130
+
131
+
5. Submission of Contributions. Unless You explicitly state otherwise,
132
+
any Contribution intentionally submitted for inclusion in the Work
133
+
by You to the Licensor shall be under the terms and conditions of
134
+
this License, without any additional terms or conditions.
135
+
Notwithstanding the above, nothing herein shall supersede or modify
136
+
the terms of any separate license agreement you may have executed
137
+
with Licensor regarding such Contributions.
138
+
139
+
6. Trademarks. This License does not grant permission to use the trade
140
+
names, trademarks, service marks, or product names of the Licensor,
141
+
except as required for reasonable and customary use in describing the
142
+
origin of the Work and reproducing the content of the NOTICE file.
143
+
144
+
7. Disclaimer of Warranty. Unless required by applicable law or
145
+
agreed to in writing, Licensor provides the Work (and each
146
+
Contributor provides its Contributions) on an "AS IS" BASIS,
147
+
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
148
+
implied, including, without limitation, any warranties or conditions
149
+
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
150
+
PARTICULAR PURPOSE. You are solely responsible for determining the
151
+
appropriateness of using or redistributing the Work and assume any
152
+
risks associated with Your exercise of permissions under this License.
153
+
154
+
8. Limitation of Liability. In no event and under no legal theory,
155
+
whether in tort (including negligence), contract, or otherwise,
156
+
unless required by applicable law (such as deliberate and grossly
157
+
negligent acts) or agreed to in writing, shall any Contributor be
158
+
liable to You for damages, including any direct, indirect, special,
159
+
incidental, or consequential damages of any character arising as a
160
+
result of this License or out of the use or inability to use the
161
+
Work (including but not limited to damages for loss of goodwill,
162
+
work stoppage, computer failure or malfunction, or any and all
163
+
other commercial damages or losses), even if such Contributor
164
+
has been advised of the possibility of such damages.
165
+
166
+
9. Accepting Warranty or Additional Liability. While redistributing
167
+
the Work or Derivative Works thereof, You may choose to offer,
168
+
and charge a fee for, acceptance of support, warranty, indemnity,
169
+
or other liability obligations and/or rights consistent with this
170
+
License. However, in accepting such obligations, You may act only
171
+
on Your own behalf and on Your sole responsibility, not on behalf
172
+
of any other Contributor, and only if You agree to indemnify,
173
+
defend, and hold each Contributor harmless for any liability
174
+
incurred by, or claims asserted against, such Contributor by reason
175
+
of your accepting any such warranty or additional liability.
176
+
177
+
END OF TERMS AND CONDITIONS

+

+
APPENDIX: How to apply the Apache License to your work.

+
comment syntax for the file format. We also recommend that a
186
+

# 🧹 Deppa
3
+
4
+
> Dependency scanner and pruner
5
+
6
+
Deppa finds and deletes dependency and build output directories (`node_modules`, `target`, `.next`, etc.) that accumulate across your projects and silently consume disk space.
7
+
8
+
Deppa is written in [Go](https://go.dev) and uses [Bubble Tea](https://github.com/charmbracelet/bubbletea) for its terminal interface.
9
+
10
+
## Usage
11
+
12
+
```bash
13
+
deppa # Scan from the current directory
14
+
deppa ~/Developer # Scan from a specific path
15
+
```
16
+
17
+
## Installation
18
+
19
+
```bash
20
+
go install github.com/Fuwn/deppa@latest
21
+
```

+
23
+
Or build from source:
24
+
25
+
```bash
26
+
git clone https://github.com/Fuwn/deppa.git
27
+
cd deppa
28
+
task build
29
+
task install
30
+
```
31
+
32
+
## Keybindings
33
+
34
+
| Key | Action |
35

39
+
| `enter` | Delete selected |
40
+
| `q` | Quit |
41
+
42
+
## Detected Directories
43
+
44
+
`node_modules`, `target`, `.next`, `.nuxt`, `__pycache__`, `.venv`, `venv`, `.gradle`, `Pods`, `zig-cache`, `zig-out`, `_build`, `.dart_tool`
45
