Any command in ticat are identitied by a path, here are some examples:
cmdshub.adddummydummy.powerdummy.quietNotice thatdummydummy.poweranddummy.quietare nothing related, they share the same branch only because the author put them that way.
These two callings do totally different things:
$> ticat dummy
$> ticat dummy.power
Ticat is a platform with huge amount of commands from different authors, the tree form provides a namespace mechanism to avoid command name conflictings.
Looking through the command tree to find what we want is not sugguested, searching by keywords is a better way.
Some builtin commands can do a excellent job in searching, any properties in a command could match by keywords: command name, help string, arg names, env ops, anyting.
However, sometimes users could still not sure what keywords they should type down. to solve this issue we introduce tags: authors put tags on commands, users search commands by tags.
There are a few builtin commands, but most of them are provided by git repos,
we add repos to ticat by hub.add, then we have new commands.
We have some conventional tags have specific meanings:
@selftest: indicate that this command are for self-testing of this repo.@ready: indicate that this is a "ready-to-go"(out-of-the-box) command.
For other tags, authors will explain them in the repo README.
So when we added a repo, the first thing will be find out what we got by searching with /:
$> ticat / <repo-name> @ready
The result might be a lot, adding more keywords could screen out what we need.
$> ticat / <repo-name> @ready <keyword> <keyword> ...
If the command source is irrelevant, remove it from the keyword list(so does for tags):
$> ticat / <keyword> <keyworkd> <keyword>...
The keyword number is up to 4, sould be enough
(TODO: this two commands are simplified)
We show how to use - to do search above, it only shows names and helps of commands.
Use + instead of - will shows all details.
+ and - are important commands to find and display infos, they have the same usage.
The difference is - shows brief messages, and + shows rich infos.
+ is a short name for command more, - is short for less. Command cmds will show a command's detail:
$> ticat cmds +
[more|+]
'display rich info base on:
* if in a sequence having
* more than 1 other commands: show the sequence execution.
* only 1 other command and
* has no args and the other command is
* a flow: show the flow execution.
* not a flow: show the command or the branch info.
* has args: find commands under the branch of the other command.
* if not in a sequence and
* has args: do global search.
* has no args: show global help.'
- args:
1st-str|find-str = ''
2nd-str = ''
3rh-str = ''
4th-str = ''
- cmd-type:
power (quiet) (priority)
$> ticat cmds -
[less|-]
'display brief info base on:
* if in a sequence having
* more than 1 other commands: show the sequence execution.
* only 1 other command and
* has no args and the other command is
* a flow: show the flow execution.
* not a flow: show the command or the branch info.
* has args: find commands under the branch of the other command.

* has no args: show global help.'
- args:
1st-str|find-str = ''
2nd-str = ''
3rh-str = ''
4th-str = ''
- cmd-type:
power (quiet) (priority)
+ - are convenient shortcuts, we will learn their usage during introducing the formal commands.
cmds is a command toolset registered on this branch,
it is also a single command itself.
The content of cmds branch:
$> ticat cmds:-
[cmds]
'display cmd info, sub tree cmds will not show'
[tree]
'list builtin and loaded cmds'
[simple]
'list builtin and loaded cmds, skeleton only'
[list]
'list builtin and loaded cmds'
[simple]
'list builtin and loaded cmds in lite style'
c is short for cmds, will display the info for a command
$> ticat cmds dbg.ccho
[echo]
'print message from argv'
- full-cmd:
dbg.echo
- args:
message|msg|m|M = ''
$> ticat c desc
[desc|d|D]
'desc the flow about to execute'
- cmd-type:
power (quiet) (priority)
$> ticat c cmds
[cmds|cmd|c|C]
'display cmd info, no sub tree'
- args:
cmd-path|path|p|P = ''
$> ticat c c
[cmds|cmd|c|C]
'display cmd info, no sub tree'
- args:
cmd-path|path|p|P = ''
+ - could use for cmds by concate them to the end of the command sequence:
$> ticat c:+
The command cmds.tree will display the command's info and it's sub-tree's.
It has a short name c.t:
$> ticat c.t desc
[desc|d|D]
'desc the flow about to execute'
- cmd-type:
power (quiet) (priority)
[lite|simple|sim|s|S]
'desc the flow about to execute in lite style'
- full-cmd:
desc.lite
- full-abbrs:
desc|d|D.lite|simple|sim|s|S
- cmd-type:
power (quiet) (priority)
[flow|f|F]
'desc the flow execution'
- full-cmd:
desc.flow
- full-abbrs:
desc|d|D.flow|f|F
- cmd-type:
power (quiet) (priority)
...
cmds.tree.simple display only the command names, convenient to observe the tree struct.
It has short name c.t.s:
$> ticat c.t.s c
[cmds]
'display cmd info, sub tree cmds will not show'
[tree]
'list builtin and loaded cmds'
[simple]
'list builtin and loaded cmds, skeleton only'
[list]
'list builtin and loaded cmds'
[simple]
'list builtin and loaded cmds in lite style'
It's highly recommended to use - instead of cmds.tree.simple,
below command could get the same result:
$> ticat c:-
When we know where the branch we are looking for, the tree-style toolset will be helpful.
cmds.flat is for display all commands in flat mode, flat ls and f are equal:
$> ticat cmds.ls
$> ticat cmds.flat
$> ticat c.f
...
[desc|d|D]
'desc the flow about to execute'
- cmd-type:
power (quiet) (priority)
[flow|f|F]
'desc the flow execution'
- full-cmd:
desc.flow
- full-abbrs:
desc|d|D.flow|f|F
- cmd-type:
power (quiet) (priority)
...
Using cmds.flat without args are barely useless because the output is way too long.
grep might helps but we have better way to looking for commands.
Filter(find) by strings, up to 4 strings, the finding strings could be anything:
$> ticat c.f <str>
$> ticat c.f <str> <str> ...
Find commands which has tag @selftest:
$> ticat c.f @selftest
[test|t]
'@selftest @ready'
- full-cmd:
examples.test
- full-abbrs:
examples|example|exam|ex|samples|sample|sam.test|t
- from:
[email protected]:innerr/examples.ticat
- flow:
dbg.step.on : ex.test.conn : ex.test.interact : ex.test.exts
...
Tags are only normal strings, we recommend that module authors adding tags in the help string, then explain the meaning of the tags in the repo README, so users could find things they want.
There are a few tags has conventional meanings:
@readymeans "ready-to-go", normally are powerful/useful flows@selftestmeans this command is for self testing modules in the repo it belongs.
Find commands which comes from git address "quick-start-mod.ticat":
$> ticat c.f quick-start-mod
[mod-1]
'a simple ticat module'
- args:
name = foo
age = unknown
- cmd-type:
file
- from:
[email protected]:innerr/quick-start-mod.ticat
Find commands which write(provide) env key-value "examples.my-key",
$> ticat c.f examples.my-key write
[conn-may-write|maywrite|mayw|mw]
'this module may-write the example key'
- full-cmd:
examples.conn-may-write
- full-abbrs:
examples|example|exam|ex|samples|sample|sam.conn-may-write|maywrite|mayw|mw
- env-ops:
examples.my-key = may-write
- from:
[email protected]:innerr/examples.ticat
...
As in the quick-start doc, + could instead of cmds.flat for global searching.
When we just added a repo to ticat, The fast way to put it into work is:
- Find what's in it with tag
@readyby searsh:ticat + <git-address> @ready. - Use
descto check out what env keys these ready-to-go commands need. - Find what commands provide those env keys (or manually set to env by
{k=v}).
cmds.flat.simple is similar to cmds.flat(c.f), just show less info.
It has short name c.f.s:
$> ticat c.f.s mysql
[exec|exe|e|E]
- full-cmd:
mysql.exec
- full-abbrs:
mysql|my.exec|exe|e|E
...
- could instead of cmds.flat.simple, just as + could instead of cmds.flat.
+ - are the only commands for searching commands under a specific branch.
Search "tree"(could be any string) in the branch cmds:
$> ticat cmds:- tree
[cmds]
'display cmd info, sub tree cmds will not show'
[cmds.tree]
'list builtin and loaded cmds'
Use + instead of - to get more detail:
$> ticat cmds:+ tree
[cmds|cmd|c|C]
'display cmd info, no sub tree'
- args:
cmd-path|path|p|P = ''
[tree|t|T]
'list builtin and loaded cmds'
- full-cmd:
cmds.tree
- full-abbrs:
cmds|cmd|c|C.tree|t|T
- args:
cmd-path|path|p|P = ''
Use = and $ if the result of + or - is not what we want.
$> ticat cmds $
[tail-sub|$]
'display commands on the branch of the last command'
$> ticat cmds =
[tail-info|=]
'display the last command info, sub tree commands will not show'
