I spent a lot of time in my past life as a web developer working with logs, typically on web servers via ssh. I would use a variety of tools, but my goto method of analyzing logs was directly on the server with *nix tools like as `tail`, `less`, and `grep` etc. As useful as these tools are, they are not without friction. I built `toolong` to be the tool I would have wanted back then. It is snappy, straightforward to use, and does a lot of the *grunt work* for you. ### Screenshots <table> <tr> <td> <img width="100%" alt="Screenshot 2024-02-08 at 13 47 28" src="https://github.com/Textualize/toolong/assets/554369/1595e8e0-f5bf-428b-9b84-f0b5c7f506a1"> </td> <td> <img width="100%" alt="Screenshot 2024-02-08 at 13 48 04" src="https://github.com/Textualize/toolong/assets/554369/c95f0cf4-426d-4d25-b270-eec0f4cfc86f"> </td> </tr> <tr> <td> <img width="100%" alt="Screenshot 2024-02-08 at 13 49 22" src="https://github.com/Textualize/toolong/assets/554369/45e7509c-ffed-44cc-b3e6-f2a7a276bbe5"> </td> <td> <img width="100%" alt="Screenshot 2024-02-08 at 13 50 04" src="https://github.com/Textualize/toolong/assets/554369/6840b626-539f-4ef9-88d9-25e0b96036b7"> </td> </tr> </table> ### Videos <details> <summary> 🎬 Merging multiple (compressed) files </summary> &nbsp; <div align="center"> <video src="https://github.com/Textualize/tailless/assets/554369/efbbde11-bebf-44ff-8d2b-72a84b542b75" /> </div> </details> <details> <summary> 🎬 Viewing JSONL files </summary> &nbsp; <div align="center"> <video src="https://github.com/Textualize/tailless/assets/554369/38936600-34ee-4fe1-9fd3-b1581fc3fa37" /> </div> </details> <details> <summary> 🎬 Live Tailing a file </summary> &nbsp; <div align="center"> <video src="https://github.com/Textualize/tailless/assets/554369/7eea6a0e-b30d-4a94-bb45-c5bff0e329ca" /> </div> </details> ## How? Toolong is currently best installed with [pipx](https://github.com/pypa/pipx). ```bash pipx install toolong ``` You could also install Toolong with Pip: ```bash pip install toolong ``` > [!NOTE] > If you use pip, you should ideally create a virtual environment to avoid potential dependancy conflicts. However you install Toolong, the `tl` command will be added to your path: ```bash tl ``` In the near future there will be more install methods, and hopefully your favorite package manager. ### Compatibility Toolong works on Linux, macOS, and Windows. ### Opening files To open a file with Toolong, add the file name(s) as arguments to the command: ```bash tl mylogfile.log ``` If you add multiple filenames, they will open in tabs. Add the `--merge` switch to open multiple files and combine them in to a single view: ```bash tl access.log* --merge ``` In the app, press **f1** for additional help. ### Piping In addition to specifying files, you can also pipe directly into `tl`. This means that you can tail data that comes from another process, and not neccesarily a file. Here's an example of piping output from the `tree` command in to Toolong: ```bash tree / | tl ``` ## Who? This [guy](https://github.com/willmcgugan). An ex web developer who somehow makes a living writing terminal apps. --- ## History If you [follow me](https://twitter.com/willmcgugan) on Twitter, you may have seen me refer to this app as *Tailless*, because it was intended to be a replacement for a `tail` + `less` combo. I settled on the name "Toolong" because it is a bit more apt, and still had the same initials. ## Development Toolong v1.0.0 has a solid feature set, which covers most of my requirements. However, there is a tonne of features which could be added to something like this, and I will likely implement some of them in the future. If you want to talk about Toolong, find me on the [Textualize Discord Server](https://discord.gg/Enf6Z3qhVr). ## Thanks I am grateful for the [LogMerger](https://github.com/ptmcg/logmerger) project which I referenced (and borrowed regexes from) when building Toolong. ## Alternatives Toolong is not the first TUI for working with log files. See [lnav](https://lnav.org/) as a more mature alternative.
