A C++ REPL / CLI for LevelDB

ldb's Issues

Move methods out of ldb.cc

In lev, things got ugly for a while because each feature/command grew in complexity. It would be nice to just start off with each feature/command in it's own file.

use clib/leveldb as dependency?

@jwerle Would it be easy to add clib/leveldb as a dependency instead of having the code checked in?

build fails due to incorrect location of libleveldb.a

This is on Debian Jessie/Sid, with Linux kernel 4.0.0 on amd64.

g++ -o ldb ldb.cc ./lib/*.cc -I./deps/leveldb/include -std=gnu++11 -lpthread ./deps/leveldb/libleveldb.a -lsnappy ./linenoise.o
g++: error: ./deps/leveldb/libleveldb.a: No such file or directory
Makefile:28: recipe for target 'ldb' failed
make: *** [ldb] Error 1

I can see that the libleveldb.a file is not in the deps/leveldb directory, but one level down, in the out-static directory:

~/src/ldb$ ls deps/leveldb/
AUTHORS          build_detect_platform*  db/   helpers/  issues/  Makefile  out-shared/  port/      table/  util/

deps/leveldb/out-static/libleveldb.a

implement suggestion lists

on auto completion, show suggestions with colorised prefixes.

Use GYP?

sublevels

The node module level-sublevel gives you a way to fake tables in leveldb, which is nice. It lets you pick a separator or defaults to \xff, then only iterates keys according to the currently selected prefix. It might be nice to make a c++ version of sublevel... Thoughts?

OSX Needs `-stdlib=libc++`

Working on a patch for the Makefile now

implement auto-complete on keys

link snappy/use compression

snappy is not getting linked atm -- should be simple.

Binary data handling should be better

There should be something like base64 support for keys and values.

implement history

move everything to cmake

...todo.

Non-Blocking --create

Hi there,

I'm interested in using ldb in a bash script. Is there a way I can run ldb ./testdb --create without going into REPL mode?

For example I want to create the db if it doesn't exist and then put a key into it.

But now, ldb ./testdb --create is blocking! :/

Why does README.md tell people to clone from a different private repo?

Why does README.md point to github.com/**0x00a**/ldb.git? Shouldn't it be github.com/**hxoht**/ldb.git?

The 0x00a looks strange and is not explained anywhere. It should at least be explained. The user 0x00a does not appear to be a contributor to this project, and his (I assume?) fork of the project is not public. Given that the official LevelDB homepage (http://leveldb.org) links to this project (the project under which I am posting this issue), I think this should be cleaned up or explained, because it looks potentially untrustworthy.

print usage on -h

should say how to use.

include linenoise in deps/ ?

Something I've been doing with some clibs is keeping there deps/ in my repo. It will allow a user who doesn't have clibs to use ldb without having to be dep'd on clibs :]

If a user types clib install hij1nx/ldb it will fetch linenoise anyways. If a user clones they will still be fine because linenoise is also there too !

What do you think ?

Remove -lpthread flag from leveldb make

Parsing puts

After you find the first whitespace, the remainder of the input gets parsed. We need a key and value. That seems simple but keys and values can have anything in them. So the question is, how should we "split" the rest of the value?

Add to homebrew

Usage example fails

Hi, I'm following the usage example shown here.

Here is my result:

ldb ./db --put foo --value bar
In excecutable 'ldb':
Unrecognized flag/option './db'

Could you provide any tips? I'm interested to write a simple bash script to populate the database, but this is stopping me.

---

On the other hand, this command actually works:

ldb -i ./db -c

Then, I'm able to successfully do:

> put foo;bar
>
> get foo
bar

move to docopt

gzip format issues - "ldb-0.0.2.tar.gz: not in gzip format"

Machine:- Ubuntu
State:- clib installed successfully.
command "clib -v" shows 1.5.0
When running command "clib install hij1nx/ldb" It says
fetch : hij1nx/ldb:package.json
gzip: ldb-0.0.2.tar.gz: not in gzip format
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors

Is it due to "ldb-0.0.2.tar.gz" is not a compressed file ?

Build failed on current version OSX

Brew part is ok:
1. brew install snappy
Result:
==> Pouring snappy-1.1.7_1.high_sierra.bottle.tar.gz

2. git Part is ok

3. make install -C ldb its NOT ok
Result:
make -C ./deps/leveldb
make[1]: *** No targets specified and no makefile found. Stop.
make: *** [leveldb] Error 2
Unfortunately I am not a make-scripts expert :-(.
Thx

New release of latest commits

Can you make some new releases of the latest commit?

Segfault on tab completion

The REPL correctly lists a moderately sized leveldb test db:

$ du -hs .
76M     .

But it crashes when I'm about to tab-complete one of the keys:

 $ ldb -i .

> get a
       terminate called after throwing an instance of 'std::regex_error'
                                                                          what():  regex_error
                                                                                              Aborted

Those keys have a format such as:

abu/day/foobaruserid/2015-05-15

Parse and colorize JSON

determine the encoding, if it is JSON, pretty print it with color

Add correct usage to man file

safeguard against completions when there is not enough data

otherwise SIGABRT

ls libc++abi.dylib: terminating with uncaught exception of type std::out_of_range: basic_string.

Support for chrome leveldb comparitor idb_cmp1

This is a feature request. Have you thought about implementing chrome's idb_cmp1 comparitor to enable working natively with webkit IndexDB storage?

This stack overflow question seems to outline some of what might be necessary: http://stackoverflow.com/questions/35074659/access-google-chromes-indexeddb-leveldb-outside-of-chrome

generate man pages from markdown

tabulate key lists so they fit nicely on the screen.

similar to this library.

^D causes strange loop...

Create man/ldb.1

output of `find in values`

should be the width of the terminal.
