## Installation
To install use pip:
```bash
xpip install xontrib-macro
# or: xpip install -U git+https://github.com/anki-code/xontrib-macro
```
## Usage
By loading the whole module - recommended for interactive usage (type `macro.`):
```xsh
xontrib load macro
with! macro.data.Write('/tmp/hello', replace=True): # more macros below
world
```
By importing certain macro - recommended for scripts:
```xsh
from xontrib.macro.data import Write
with! Write('/tmp/hello', replace=True): # more macros below
world
```
## Macros
### Block (xonsh builtin)
```python
from xonsh.contexts import Block
with! Block() as b:
any
text
here
b.macro_block
# 'any\ntext\nhere\n\n'
b.lines
# ['any', 'text', 'here', '']
```
### data.Write
Write a file from block ([rich list of parameters](https://github.com/anki-code/xontrib-macro/blob/main/xontrib/macro/data.py#L12)):
```xsh
from xontrib.macro.data import Write
with! Write('/tmp/t/hello.xsh', chmod=0o700, replace=True, makedir=True, format={'name': 'world'}, verbose=True):
echo {name}
## Make directories: /tmp/t
## Write to file: /tmp/t/hello.xsh
## Set chmod: rw- --- ---
## Set exec: rwx --- ---
/tmp/t/hello.xsh
# world
```
There is also `data.Replace()` macro with `mode='w', replace=True, makedir=True, replace_keep='a'`.
Note! There is an upstream issue described below in "Known issues" section - the first lines that begin from `#` will be ignored in the block. As workaround to create [shebang](https://en.wikipedia.org/wiki/Shebang_(Unix)) use `Write(..., shebang="#!/bin/xonsh")`.
### data.JsonBlock
Make json block and use it as dict:
```python
from xontrib.macro.data import JsonBlock
with! JsonBlock() as j:
{"hello": "world"}
j['hello']
# 'world'
```
### data.XmlBlock
Simple XML macro context manager from [xonsh macro tutorial](https://xon.sh/tutorial_macros.html#context-manager-macros). This will return the parsed XML tree from a macro block
```xsh
from xontrib.macro.data import XmlBlock
with! XmlBlock() as tree:
Hello world!
Hello!
type(tree)
# xml.etree.ElementTree.Element
tree.find('body').text
# '\n Hello!\n '
```
### run.Once
Run the code once and save mark about it in [XONSH_DATA_DIR](https://xon.sh/envvars.html#xonsh-data-dir).
In the next run the code will not be executed if it was not changed. If the code will be changed it will be executed again.
Example:
```python
from xontrib.macro.run import Once
with! Once('First install'):
if $(which pacman):
pacman -S vim htop
elif $(which apt):
apt update && apt install -y vim htop
```
### podman.RunInPodman
```xsh
from xontrib.macro.container import RunInPodman as podman
with! podman(): # default: image='ubuntu', executor='bash'
echo hello
# hello
```
### podman.RunInXonshPodman
```python
from xontrib.macro.container import RunInXonshPodman as Pod
with! Pod(): # default: image='xonsh/xonsh:slim', executor='/usr/local/bin/xonsh'
echo Installing...
pip install -U -q pip lolcat
echo "We are in podman container now!" | lolcat
# We are in podman container now! (colorized)
```
This is the same as:
```python
podman run -it --rm xonsh/xonsh:slim xonsh -c @("""
pip install -U -q pip lolcat
echo "We are in podman container now!" | lolcat
""")
```
### signal.DisableInterrupt
This macro allows disabling SIGINT (Ctrl+C) for group of commands.
```xsh
from xontrib.macro.signal import DisableInterrupt
echo start
with! DisableInterrupt():
echo 'sleep start'
sleep 10
echo 'sleep end'
echo finish
# start
# sleep start
# [Press Ctrl+C]
# KeyboardInterrupt will be raised at the end of current transaction.
# sleep end
# Exception KeyboardInterrupt: KeyboardInterrupt was received during transaction.
```
## Known issues
Context Manager Macro picks up comments from outside the block and ignore the initial comments in the block ([4207](https://github.com/xonsh/xonsh/issues/4207)). We can fix it in the xontrib by checking the indentation in the beginning line and the end line. PR is welcome!
