# Claw2 Formats
|
|
|
|
## .c2l format
|
|
|
|
The .c2l format is the server package list for Claw2.
|
|
|
|
In an exception to the rule, this file only exists on the server.
|
|
|
|
It is used solely in the main package list panel.
|
|
|
|
It is a file made up of lines.
|
|
|
|
Each line contains a package name, followed by a dot, followed by the package version.
|
|
|
|
## .V.c2p format
|
|
|
|
The .V.c2p (where V is the version) format is the entire contents of the package view panel,
|
|
as text, with newlines, in UTF-8.
|
|
|
|
This is used when a package is selected in Claw2.
|
|
|
|
## .c2x format
|
|
|
|
The .c2x format is the actual installation script for the package.
|
|
|
|
It is executed by svc-claw-worker.
|
|
|
|
It's loaded in all-at-once, then it's gmatched
|
|
with the pattern [^\n]+.
|
|
|
|
A line starting with "?" represents a dependency.
|
|
|
|
A line starting & ending with "/" represents a directory creation.
|
|
|
|
And a line starting with "+" represents a file.
|
|
|
|
Package metadata is not implied.
|
|
|
|
Thus, a valid .c2x is:
|
|
|
|
```
|
|
?neo
|
|
/apps/
|
|
+apps/app-carrot.0.c2p
|
|
+apps/app-carrot.c2x
|
|
```
|
|
|
|
## Claw2 Architecture
|
|
|
|
app-claw is a very dumb client, but the only thing that'll bother
|
|
to parse a .c2l (because it has package list/search),
|
|
and the only thing that cares about version numbers.
|
|
|
|
The purpose of it is to provide an older-CLAW-style GUI.
|
|
|
|
It *may* take an argument, in which case a package panel is opened,
|
|
otherwise the main search panel is opened.
|
|
|
|
When it wants to do anything, it shuts itself down, running svc-claw-worker.
|
|
|
|
svc-app-claw-worker does all package consistency & such work.
|
|
|
|
It can only be run from app-claw, and runs app-claw after it's done.
|
|
|
|
It takes 5 arguments:
|
|
|
|
1. The target filesystem proxy.
|
|
2. The target package name. This package is viewed in app-claw after completion.
|
|
3. The source to download files from.
|
|
If nil, the package is being deleted.
|
|
Otherwise, can either be a proxy or a string.
|
|
Proxy means it's a filesystem,
|
|
string means it's an internet base.
|
|
4. Checked flag
|
|
5. primary inet card proxy, if any
|
