Using build constraints to skip entire hierarchies in go
This is a nice change to let go apply build constraints to prune a hierarchy of packages. After the change, if there is a file skip.go in a package, then the build constraint for the file refers to the entire package and not just to the file. Also, if the p...

Random notes on the Go 1.4 runtime.
These are some notes on the Go 1.4 Run-Time written while working on the new Clive kernel.
I just copied the text from the TR, which will be linked at the Lsub page and updated in the future.

They should be easy to follow using a Go 1.4 tree because the pa...

Commands and channels in Clive: Sam is gone.
Recently I removed the port of the venerable Sam command language in Clive. This command language can do things like iterate for all portions of text matching addresses indicated by regular expressions and then, for example, for each portion matching anothe...

Nested control requests in Clive ZX file trees
In a previous post I wrote about ZX file system stacks in Clive. Now I look into their control interfaces, which exhibit a nice feature shown here. When a ZX file tree operates by relying on another ZX tree deeper in the stack, it adapts its control interfa...

File System Stacks in Clive
In clive, The different file sys-
tems and file system tools can be combined and used together to provide features like file
access, backups, history dumps, and performance measurement. For example, this is a non-trivial stack out of the multiple ones we us...

Lsub go changes
For the Clive OS being developed at Lsub, we have modified the Go
compiler in several important aspects. This post is a copy of a TR
documenting the changes we made. INTRODUCTION Clive is written using the Go programming language

Given you're altering the language, have you given any thought to shortening the noisy

    foo, err := bar()
    if err != nil {
        return 0, err
    }

Given error is a built-in type, I've been wondering if

    on err: return 0, err

would be better. No explicit check against nil, because bool or error are accepted, and no need for the careful reader to check != has been used and not ==.

When "cd" has no arguments
In a previous post  I wrote about commands and channels in Clive. Since then, things have evolved a bit I think it's worth a post. The cd command, to change the current directory, no longer has a file name argument. Instead, it receives the directory entry ...

From a paper I´m writing...

This paper on ZX was written using ZX both to access the source and to run the programs necessary to convert it to PDF. The network link RTT was 74ms according to ping(8). It was as convenient for the authors as using the local disk.

Go and unix traditions are a good match
Recently I had start writing a paper on Clive's ZX (more on this soon) and had to add citations in it. I'm writing the paper using  wr(1) , the Clive text formatter used to write manual pages, papers, and everything. Because we had the entire set of bibliog...

Limiting the number of concurrent processes
In some cases, a task can be easily split into multiple concurrent child tasks, but it is not a good idea to spawn each of of the child tasks as a concurrent process. For example, some commands in Clive go through a tree to synchronise it, or to poll each n...
