Its documentation frames the format as a notebook-like way to keep work logs editable in any text editor while still supporting terminal queries and reports. ### Project history Jan Heuermann created klog as a small Go tool and file format for human-readable `.klg` files. Version 1.0 was released on 2021-02-06 with commands for totals, reports, tags, and bookmarks; version 2.0 followed in March 2021 with commands for creating records and starting or stopping open-ended time ranges. The file-format side became more explicit in version 2.6 on 2021-07-25, when the changelog records the first version of the formal file format specification. The repository notes that the command-line tool and the file-format specification use independent version numbering and different license terms. ### Adoption history klog's adoption has been strongest among plain-text productivity users rather than large platform deployments. The project documentation lists installs through Homebrew, AUR, Nix, openSUSE, Go, and downloadable binaries, which is typical for a small cross-platform Go CLI that appeals to users already comfortable storing data in versionable text files. ### How it is used A user writes records in `.klg` files, with dates, summaries, time ranges, durations, tags, open-ended ranges, and should-total annotations. The `klog` command then searches, totals, reports, edits bookmarks, and supports workflows where the same file remains readable without the tool. ### Why package nerds care klog is package-nerd catnip because it treats the data format as the product, not merely as an implementation detail. It belongs in the lineage of Ledger, todo.txt, Markdown, and other small tools where durable text, predictable CLI output, and easy packaging matter more than a service backend. ### Timeline - 2021-02-02: v1.0-rc release published on GitHub. - 2021-02-06: v1.0 release added report, tags, bookmark, and renamed `eval` to `total`. - 2021-03-16: v2.0 release added create, track, start, and stop commands. - 2021-03-19: v2.1 release provided a native Windows binary. - 2021-07-25: v2.6 release published the first file-format specification version. - 2021-10-07: v3.0 release added named bookmarks, editor integration, and more report aggregation options. ### Related projects - klog is related to plain-text accounting and productivity tools such as Ledger, hledger, todo.txt, Timewarrior, and Taskwarrior, but it keeps the domain focused on human-readable time logs. ### Sources -
