# Merge files on install
|
|
|
|
Dotdrop allows to merge multiple files into one using the jinja2's `include` directive.
|
|
|
|
For example let's consider you want to keep your `vimrc` split into multiple parts in dotdrop
|
|
* `<dotpath>/vimrc.d/top`: top part of the file
|
|
* `<dotpath>/vimrc.d/bottom`: bottom part of the file
|
|
|
|
And you want dotdrop to merge all those files into `~/.vimrc` whenever you process your vimrc with dotdrop.
|
|
|
|
First make sure `~/.vimrc` is present in your config file
|
|
```yaml
|
|
...
|
|
dotfiles:
|
|
f_vimrc:
|
|
dst: ~/.vimrc
|
|
src: vimrc
|
|
profiles:
|
|
hostname:
|
|
dotfiles:
|
|
- f_vimrc
|
|
...
|
|
```
|
|
|
|
Note that the subfiles (`vimrc.d/top` and `vimrc.d/bottom`)
|
|
are not known to the config and do not need to be.
|
|
|
|
Edit the stored vimrc file to include the other files, for example:
|
|
```bash
|
|
$ cat <dotpath>/vimrc
|
|
{%@@ include 'vimrc.d/top' @@%}
|
|
filetype on
|
|
set t_Co=256
|
|
set tw=0
|
|
set tabstop=2
|
|
set shiftwidth=2
|
|
set expandtab
|
|
set nocompatible
|
|
set nomodeline
|
|
syntax on
|
|
{%@@ include 'vimrc.d/bottom' @@%}
|
|
```
|
|
|
|
The `include` path parameter needs to be relative to your `dotpath`.
|
|
|
|
Dotdrop will then automagically include the files into your vimrc when handling `f_vimrc`.
|
|
|
|
## Merge all files in a directory
|
|
|
|
To include all files in a directory, a combination of
|
|
[dynvariables](../config-details.md#entry-dynvariables)
|
|
and [jinja2 directives](https://jinja.palletsprojects.com/en/2.11.x/) have to be used.
|
|
|
|
Let's say all files in `<dotpath>/toinclude` need to be included into a dotfile.
|
|
|
|
First define a [dynvariables](../config-details.md#entry-dynvariables)
|
|
in the config file which will look for files to include in the above directory:
|
|
```yaml
|
|
dynvariables:
|
|
allfiles: "cd {{@@ _dotdrop_dotpath @@}}; find toinclude/ -type f | xargs"
|
|
```
|
|
|
|
Note that `_dotdrop_dotpath` is part of the built-in variables
|
|
(for more see [template variables](../templating.md#template-variables)).
|
|
|
|
And then use the generated list in the dotfile template:
|
|
```
|
|
{%@@ for f in allfiles.split() @@%}
|
|
{%@@ include f @@%}
|
|
{%@@ endfor @@%}
|
|
```
