README
## conda-tree
conda dependency tree helper
## Install
```bash
conda install -c conda-forge conda-tree
```
If you're using python 3.9 you might have to run:
```bash
conda install -c conda-forge conda-tree 'networkx>=2.5'
```
to make sure the right networkx version is installed.
## Conda sub-command
When conda-tree is installed on the base environment, you can use the "tree" sub-command from any env:
```bash
# normal usage
(base) $ conda tree leaves
package-1
package-2
# activate another env
(base) $ conda activate env2
# no need to install conda-tree on env2
(env2) $ conda tree leaves
package-x
package-y
```
## Features
### Query the dependency tree
```bash
# packages that no other package depends on
$ conda-tree leaves
samtools
bcftools
etc
# dependencies of a specific package
$ conda-tree depends samtools
curl
xz
libgcc
zlib
# which packages depend on a specific package
$ conda-tree whoneeds xz
samtools
bcftools
htslib
python
# dependency cycles
$ conda-tree cycles
pip -> python -> pip
pip -> wheel -> python -> pip
```
### Dependencies in tree form
```bash
# dependencies in a tree form
# (redundancies are hidden by default)
$ conda-tree depends -t sqlite
sqlite==3.29.0

```
### Query another env
```bash
# query by path
$ conda-tree -p /conda/envs/trinity leaves
trinity
# query by name
$ conda-tree -n trinity leaves
trinity
```
### Query package files
```bash
# find which package owns a file
$ conda-tree -n graphviz who-owns bin/dot
graphviz bin/dot
graphviz bin/dot2gxl
graphviz bin/dot_builtins
# find dangling files that aren't owned by any package
$ conda-tree -n base unowned-files
/conda/LICENSE.txt
$ conda-tree -n graphviz unowned-files
/conda/envs/graphviz/var/cache/fontconfig/b67b32625a2bb51b023d3814a918f351-le64.cache-7
/conda/envs/graphviz/var/cache/fontconfig/f93dd067-84cf-499d-a5a8-645ff5f927dc-le64.cache-7
/conda/envs/graphviz/var/cache/fontconfig/923e285e415b1073c8df160bee08820f-le64.cache-7
/conda/envs/graphviz/fonts/.uuid
```
### Generate a minimal set of packages to re-create the env
```bash
# can be used to re-create a env with conda create -n --file
$ conda-tree -n graphviz leaves --export
conda-forge::graphviz=2.48.0=h85b4f2f_0
```
### Generate a graph of the dependency tree
```bash
# export a graphviz dot notation file of the dependencies tree
$ conda-tree deptree --dot > file.dot
$ conda-tree depends --dot > file.dot
$ conda-tree whoneeds --dot > file.dot
# then render to pdf with graphviz's dot tool
$ dot -Tpdf file.dot -o tree.pdf
```
