The weather looks promising, so maybe a couple of rides during the week 🤞
19+
20+
At the end of March I planned to [start testing AstroNvim v6 and :fontawesome-brands-neovim: Neovim 0.12](#neovim) (for its up coming release). Looking at the migration guide though, it was so simple I started already. Now I am using AstroNvim v6 and Neovim nightly as the day to day setup.
21+
22+
I added the [:fontawesome-brands-github: Markdown language pack](https://github.com/AstroNvim/astrocommunity/tree/main/lua/astrocommunity/pack/markdown){target=_blank} to the Astronvim v6 config, which automatically installs treesitter parsers for markdown and the marksman language server. Marksman provides completion for heading when typing the `#` character, so correct in-page links are easy to create.
23+
24+
I finalised the [Debian Linux Post Install scripts](), separating each tool into its own script.
25+

27+
28+
29+
## Neovim
30+
31+
AstroNvim is used as the base configuration for Neovim. AstroNvim turns Neovim in to a feature rich editor (IDE) whist still keeping the editor extremely fast and with near instant startup.
32+
33+
There is [:fontawesome-brands-github: a pull request containing AstroNvim v6 changes along with a migration guide](https://github.com/AstroNvim/AstroNvim/pull/2822){target=_blank}
34+
35+
### Preparing to Testing AstroNvim v6
36+
37+
The `dra` tool was used to download and install the Neovim AppImage from the Neovim GitHub repository releases.
38+
39+
As its a pre-release, the binary was installed for the current user in their `~/.local/bin` directory (which should already be on the execution path).
40+
41+
!!! NOTE "Shell script to install Nightly Neovim release for current user"
42+
```shell
43+
#!/usr/bin/env bash
44+
45+
# Install the pre-release version of Neovim from GitHub, for the current user
46+
47+
echo "# ---------------------------------------"
48+
echo "Neovim hyper-configurable editor - installed for all users in `/usr/local/bin`"
49+
# remove the existing nvim binary as DRA fails to override the file
50+
# sudo rm -f /usr/local/bin/nvim
51+
52+
# Install nvim.appimage nightly release tag and rename to nvim-nightly
53+
dra download --tag nightly --select nvim-linux-x86_64.appimage --install --output ~/.local/bin/nvim-nightly neovim/neovim
54+
55+
echo "# ---------------------------------------"
56+
echo ""
57+
```
58+
59+
60+
Clone a separate copy of [practicalli nvim-astro5](https://github.com/practicalli/nvim-astro5)
61+
62+
```shell
63+
git clone --depth=1 git@github.com:practicalli/nvim-astro5 ~/.config/nvim-astro6
64+
```
65+
66+
Change into the `nvim-astro6` directory and create a new git branch.
67+
68+
```shell
69+
git branch nvim-astro6
70+
```
71+
72+
73+
!!! EXAMPLE
74+
```shell-output
75+
❯ git branch nvim-astro6
76+
77+
❯ git branches
78+
* main 3341c1d snippet: update to year 2026 in post header
79+
nvim-astro6 3341c1d snippet: update to year 2026 in post header
80+
remotes/origin/HEAD -> origin/main
81+
remotes/origin/main 3341c1d snippet: update to year 2026 in post header
82+
83+
❯ git checkout nvim-astro6
84+
Switched to branch 'nvim-astro6'
85+
```
86+
87+
88+
Create a shell alias to launch neovim nightly with the astronvim v6 branch. This simplifies the command needed (and means I dont have to remember it).
89+
90+
I added the shell alias to the [practicalli/dotfiles shell-aliases](https://github.com/practicalli/dotfiles/blob/main/shell-aliases) file
91+
92+
!!! NOTE "Launch Neovim nightly with AstroNvim v6 config to test Practicalli customisations"
93+
```shell
94+
alias astro6="NVIM_APPNAME=nvim-astro6 nvim-nightly"
95+
```
96+
97+
### Update Config
98+
99+
Edited `lua/lazy_setup.lua` and commented line 4 which defined a `version` key for AstroNvim/AstroNvim plugin
100+
101+
Comment the `version` key and value (it will be changed to `version = ^6` once AstroNvim v6 is released).
102+
103+
Add a `branch` key with the value of `v6`.
104+
105+
!!! NOTE "Configure Astronvim plugin to use branch v6"
106+
```lua
107+
require("lazy").setup({
108+
{
109+
"AstroNvim/AstroNvim",
110+
-- version = "^5", -- Remove version tracking to elect for nightly AstroNvim
111+
branch = "v6", -- Use branch until AstroNvim v6 released
112+
--
113+
},
114+
--
115+
},
116+
} --[[@as LazyConfig]])
117+
```
118+
119+
!!! INFO "Initiall the branch was not set correctly, causing errors"
120+
[Testing AstroNvim v6](#testing-astronvim-v6) highlights errors that were caused because the branch was not set to v6.
121+
122+
123+
AstroNvim v6 uses newer versions of its three core plugins. A new plugin config is created to ensure the new versions are installed.
124+
125+
!!! NOTE "Created astronvim plugin file with specific versions"
126+
```lua title="lua/plugins/astronvim.lua"
127+
return {
128+
{ "AstroNvim/astrocore", version = false, branch = "v3" }
129+
{ "AstroNvim/astrolsp", version = false, branch = "v4" },
130+
{ "AstroNvim/astroui", version = false, branch = "v4" },
131+
}
132+
```
133+
134+
EDIT: Updated the AstroCommunity plugin spec to use v6.
135+
136+
!!! NOTE "Add branch v6 to AstroCommunity plugin spec"
137+
```lua title="lua/community.lua"
138+
---@type LazySpec
139+
return {
140+
-- "AstroNvim/astrocommunity", -- default release
141+
142+
{ "AstroNvim/astrocommunity", branch = "v6" }, -- AstroNvim v6
143+
}
144+
```
145+
146+
147+
148+
### Testing AstroNvim v6
149+
150+
!!! INFO "The AstroNvim branch was not set correctly, causing the following errors"
151+
[Testing AstroNvim v6](#testing-astronvim-v6) highlights errors that were caused because the branch was not set to v6.
152+
153+
AstroNvim v5 was installed due to the misconfiguration and had incompatibilities with the new implementation of Treesitter.
154+
155+
156+
157+
Ran `astro6` and then `SPC p a` to let neovim automatically update plugins and supporting development tools.
158+
159+
Ran a second update, `U`, from the Lazy popup to ensure everything was up to date.
160+
161+
162+
!!! EXAMPLE "Error in User Autocommands"
163+
```shell-output
164+
Error in User Autocommands for "LazyLoad":
165+

172+
```
173+
174+
My initial assumption is a package that doesnt like the new version of treesitter. Probably something from AstroCommunity.
175+
176+
Although I have a couple of other plugins from their GitHub repository.
177+
178+
179+

180+

```
191+
192+
Asking in the Next channel on the AstroNvim discord community, the believed I should run `:Lazy update`
193+
194+
When using `astro6` to open the Practicalli dotfiles project, opening the `dev-.sh` file caused the following error.
195+
196+

### Fixing my config
226+
227+
I made a typo. in `lua/lazy_setup.lua` I added `branch = ^6` when I should have added `branch = v6`.
228+
229+
Everything seems to work now. There may be issues with specific plugins though. More time to test during the week.
230+
231+
232+
### Testing Extra Plugins and Tools
233+
234+
Using AstroNvim v6 for my every day tasks a simple way to start testing all the extra plugins and tools I use are working correctly.
235+
236+
As there have been changes in Treesitter, it is probable that those plugins would need updating.
237+
238+
239+
Issues:
240+
241+
- Neogit: two popup dialogs shown when deleting a hunk in the git status window
242+
243+
244+
Resolved:
245+
246+
- Marksman: I forgot to install the tool via Mason :face_palm:
247+
248+
249+
Working correctly:
250+
251+
- VM Visual Cursors
252+
253+
254+
## Debian Linux
255+

### Remove unneeded locals
260+
261+
262+

## Bash scripting
290+
291+
There are a long list of tests that can be used within an `if` statement when writing a bash script.
292+
293+
The Gnu Bash Manual describes [Conditional Expressions](https://www.gnu.org/software/bash/manual/html_node/Bash-Conditional-Expressions.html#Bash-Conditional-Expressions-1){target=_blank} in detail, as does the [test manual page](https://www.man7.org/linux/man-pages/man1/test.1.html){target=_blank}.
294+
295+
Commonly used tests include:
296+
297+
- ! expression: True if the expression is false.
298+
- -n string: True if the length of the string is greater than zero.
299+
- -z string: True if the length of the string is zero. That is, it's an empty string.
300+
- string1 = string2: True if string1 is the same as string2.
301+
- string1 != string2: True if string1 is not the same as string2.
302+
- integer1 -eq integer2: True if integer1 is numerically equal to integer2
303+
- integer1 -qt integer2: True if integer1 is numerically greater than integer2
304+
- integer1 -lt integer2: True if integer1 is numerically less than integer2
305+
- -d directory: True if the directory exists.
306+
- -e file: True if the file exists.
307+
- -s file: True if the file exists with a size of more than zero.
308+
- -r file: True if the file exists and the read permission is set.
309+
- -w file: True if the file exists and the write permission is set.
310+
- -x file: True if the file exists and the execute permission is set.
