Re: [go-nuts] Re: need a package to read/write shell history flat file database
This package (FZF) is also using the history file, perhaps there's something usable inside. https://github.com/junegunn/fzf Op zondag 11 februari 2024 om 06:41:11 UTC+1 schreef Kurtis Rader: > Thanks, but that requires me to implement the code I would rather not have > to reinvent given that shells like Bash, Ksh, and Fish already have code to > do what I need.

Re: [go-nuts] Re: need a package to read/write shell history flat file database
Thanks, but that requires me to implement the code I would rather not have to reinvent given that shells like Bash, Ksh, and Fish already have code to do what I need. The problem is that those solutions are written in C and C++ respectively rather than Go. While I consider myself an expert in C (having started programming with it around 1985) I am only minimally competent in C++. I'll translate the Fish C++ code into Go if I have to but am hoping there is a published Go equivalent to save me that effort. P.S., This is to remove the dependency on a daemon process to update a BoltDB database by the Fish shell. The BoltDB dependency (go.etcd.io/bbolt) greatly increases the size and complexity of the Fish shell. The opaque binary database managed by BoltDB is also annoying. It would be preferable to use a flat file database using JSON or text protobufs for storing command history.

There is also https://pkg.go.dev/github.com/peterh/liner, which also does not handle history persistence, but which makes it relatively easy to add. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

[go-nuts] Re: need a package to read/write shell history flat file database
The only solution I can find that gets close to my requirements is https://github.com/ergochat/readline, but AFAICT it does not handle updates to the on-disk history file by concurrently executing processes.
