# brewlog
|
||
|
||
### Why?
|
||
|
||
I wrote [ `brewlog`](https://github.com/robocopAlpha/brewlog/) to patch a minor but IMHO a significant shortcoming I feel [homebrew](https://brew.sh/) has had for very long time. It is the ability to log what homebrew does. IMO it doesn’t have to be something very sophisticated i.e. integration with system-log, etc.. So, I worked on a basic idea I got from [this particular issue](https://github.com/Homebrew/legacy-homebrew/issues/10430) and developed `brewlog`.
|
||
|
||
|
||
|
||
### Why bother with a log file, when brew is so stable?
|
||
|
||
`brew` is generally very stable, but occasionally it breaks compatibility when it is upgrading some packages and removes some “obsolete” versions. Generally this is fine, but in certain cases the user wants to retain those packages for compatibility with something else. I recently faced [a problem](https://github.com/brewsci/homebrew-base/issues/29) due to this. While `brewlog` can’t prevent something like this from happening, but it logs `brew` activity so it is much easier to troubleshoot (by identifying what package(s) were added/removed).
|
||
|
||
|
||
|
||
### What can `brewlog` do ?
|
||
|
||
`brewlog` is simple solution that can:
|
||
|
||
+ `log` homebrew/linuxbrew activity (`STDOUT` and `STDERR`) to a logfile (default: `~/Logs/brew.log`)
|
||
+ because brewlog is a a new command (and not an alias), the user still retains the freedom to run `brew [command] [formula]` in case they do not want to log some brew activity.
|
||
+ `tail` the `brew.log` file to display selected number of lines.
|
||
+ `archive` the brew.log file (user has to explicitly invoke this command to archive).
|
||
+ The `brew.log` is removed during archiving, a new log file is created on the next run of `brewlog`.
|
||
|
||
Now you're easily able to track the changes made to your system while running `brew upgrade`or `brew cleanup`.
|
||
|
||
|
||
|
||
### How to use
|
||
|
||
#### a) Install from binary
|
||
|
||
1. Download the latest binary from the releases (should run on *nix with a homebrew installation).
|
||
2. `mv brewlog /usr/local/bin/brewlog` or to some other place that is in your `$PATH`.
|
||
3. Familiarize yourself by running `brewlog —help`.
|
||
|
||
#### b) Install from source
|
||
|
||
The script [`install.sh`](https://github.com/robocopAlpha/brewlog/blob/master/install.sh) automatically picks the place to install brewlog by detecting the location where the `brew` binary is placed in your system `$PATH`.
|
||
|
||
```sh
|
||
# Install
|
||
curl -sSL 'https://raw.githubusercontent.com/robocopAlpha/brewlog/master/install.sh' | bash
|
||
# Show help
|
||
brewlog --help
|
||
```
|
||
|
||
#### c) Install from source with modifications
|
||
|
||
```sh
|
||
# download
|
||
curl -OJL 'https://raw.githubusercontent.com/robocopAlpha/brewlog/master/install.sh'
|
||
# Review/Modify code
|
||
bat install.sh
|
||
nano install.sh
|
||
# Install
|
||
sh install.sh | bash
|
||
# Show help
|
||
brewlog --help
|
||
```
|
||
|
||
|
||
|
||
#### Examples using brewlog

### Notice about the command `brew log`:
|
||
|
||
+ Not to be confused with `brew log` which shows the commit history (similar to `git log`).
|
||
+ I'm open to a new name, but for now as I personally don’t use `brew log`, I had no “merge conflicts” in my brain while assigning `brewlog` to achive my desired result of logging brew output :) [*IMHO* `brew history` *might have been a better name for* `brew log`]
