2017-08-19Remove 'shakespeare' packageTeddy Wing
Get rid of this package because we're no longer using it. Instead we're going it alone for i18n (dde184a6e24b88f8d6628f4652d5c42ed0f016b2). Also delete the translation .msg file.
2017-08-19I18n.hs: Implement custom i18n using Haskell data typesTeddy Wing
Follow the example https://wiki.haskell.org/Internationalization_of_Haskell_programs_using_Haskell_data_types to get i18n. Get rid of the Shakespeare-I18N code. The idea of using text files to define translation strings was nice, but since I couldn't get it working with ease and couldn't find examples outside of a Yesod context, I decided to chuck it and go with the alternative, simpler approach. Really liking this system. Simplified things a bit from the example since we only need to show one language at a time. Will need to figure out how to use the same language throughout the program.
2017-08-19Try to get I18n workingTeddy Wing
An unsuccessful attempt at getting i18n working through Shakespeare. Had a little help from: https://gist.github.com/nicolashery/f87467fb37da2b00cec1eed028f51e60 Unfortunately, I can't figure out how to get this working. Even before, without the locale stuff and defining a custom `translate` function, when I tried using Shakespeare's `_{}` function, I was, and still am, getting this error: src/Plugin/GitHubCommit.hs:38:29: error: Data constructor not in scope: MsgGitHubCommitRepoURLNotFound Yes, obviously, that makes sense. But how do I get it to be in scope if it isn't even in my code? What? I'm giving up on Shakespeare for i18n. It was a nice idea, I liked the fact that strings were stored in external files, but I don't know how to do this, I can't find the right resources online to use this in a non-web non-template context, and it's becoming a pain. Going to get rid of all this code and just use regular Haskell data types to do it as described in https://wiki.haskell.org/Internationalization_of_Haskell_programs
2017-08-19Set up i18nTeddy Wing
en.msg: * Remove comment lines because apparently comments aren't allowed by the parser * Change data type to `T.Text` to match the import from the `I18n` module GitHubCommit.hs: Import the `I18n` module because we'll be testing it in context in a bit, but for now just want to get the module code to compile. I18n.hs: Follow the example on http://www.yesodweb.com/book/internationalization to make a function for proper internationalisation.
2017-08-18Add 'shakespeare' packageTeddy Wing
To allow us to take advantage of its `Text.Shakespeare.I18N` feature.
2017-08-18Add an English i18n fileTeddy Wing
This will enable us to translate our messages into multiple languages using Yesod's Shakespeare package.

2017-08-17gitRemoteSetOriginAction: Upsert instead of insertTeddy Wing
I had used `INSERT` as a placeholder while trying to get the plugin working properly. This would create a row every time the "git remote set origin" command was invoked. What I really wanted was an upsert. Looked through a number of different ways of accomplishing that in SQLite: - https://stackoverflow.com/questions/418898/sqlite-upsert-not-insert-or-replace/7511635#7511635 - https://stackoverflow.com/questions/15277373/sqlite-upsert-update-or-insert Ended up settling on this solution from CL.: https://stackoverflow.com/questions/20323174/upsert-in-sqlite/20326705#20326705 It seemed to be pretty clean and understandable, so I leveraged that approach.
2017-08-17gitRemoteSetOriginAction: Use regex capture groupTeddy Wing
Finally figured out how to get a capture group out of the regex match. Needed to coerce as a two-dimensional `String` list. Thanks to: - https://stackoverflow.com/questions/24699279/cant-capture-a-group-in-a-string - https://stackoverflow.com/questions/6729158/find-all-capturing-groups-of-a-regular-expression Get the captured group and set it to the URL to insert into the database. It lives in the second element of the first list: Prelude Text.Regex.TDFA> "git remote set origin https://example.new" =~ "^git remote set origin ([^ ]+)$" :: [[String]] [["git remote set origin https://example.new","https://example.new"]] Prelude Text.Regex.TDFA> "" =~ "^git remote set origin ([^ ]+)$" :: [[String]] []

2017-08-17Add GitRemoteSetOrigin pluginTeddy Wing
This plugin provides a command to set a git commit repo URL for use with the `GitHubCommit` plugin. Typing git remote set origin URL in chat will set that URL to the current channel. Problems: * Can't figure out how to use capture groups, so the entire matched message string comes back, not just the URL * Need to upsert instead of insert into the database

2017-08-17Message: Add a function to get the `text` field as a stringTeddy Wing
Clean up some of the calls to get the `text` field by adding a function that abstracts the call to `Data.Text(unpack)`.
2017-08-17Change `Plugin` and `Message` from `String` to `Data.Text`Teddy Wing
Use the `Data.Text` type instead of `String` in most of the places we use it in `Plugin` and `Message`. This allows us to more easily pass data between the IRC package. No more kludgy `pack`s and `unpack`s in our IRC message handler. The one thing we couldn't convert was our regex. From what I understand (https://stackoverflow.com/questions/14922579/haskell-regular-expressions-and-data-text#14922626), the regex library I'm using doesn't support `Data.Text`, so use `String`s for that instead.
2017-08-16handlePrivmsg: call out to plugins in QUERYTeddy Wing
When a PRIVMSG comes in from an individual user instead of a channel, invoke our plugins so we're doing the same thing in both cases.
2017-08-16IRC.hs: Remove old commented codeTeddy Wing
This was there as a test but didn't work. It's no longer needed, so we can remove it.
2017-08-16IRC.hs: Handle `Nothing` branchesTeddy Wing
Handle our un-handled `Nothing` branches. Make `privmsgFromPlugin` return a `Maybe` so we can decide whether or not to send a message upstream. If we do get a `Nothing` from `privmsgFromPlugin`, just return unit and don't send any chat message, since no plugin matched and thus none could respond.
2017-08-16handlePrivmsg: Move duplicated code to new functionTeddy Wing
We have some code that's duplicated in both branches of the `Either` case statement that sends a response over IRC. Extract that to a new function that can be shared between the two case statements to try to reduce repetition. Took me a while to wrangle the monads to get this, but it's in working condition now. Need to add the commented `Nothing` branch in so I'm handling all the cases.
2017-08-16Remove commented code from a0d21d9aed3a38e98e622fbae5fcab3e91c5ddeeTeddy Wing
I had a bunch of code commented from earlier and from false starts when working on integrating my plugins and the IRC message handler. Remove these commented lines now as they are no longer relevant. The actual code is functioning.
2017-08-16TODO: Add a few new tasksTeddy Wing
2017-08-16Connect plugins to IRCTeddy Wing
Instead of sending a hard-coded string message over IRC, now invoke our plugin list. Now, IRC messages get matched against our plugin list, and if any plugin matches, its return string gets posted to the appropriate channel. Move the database connection inside the plugin so that we can continue to access it without having to pass in the DB connection. I didn't want to connect to the database in the IRC code because it doesn't relate, and I don't have a good enough grasp of monads to know if I can create the connection in "Lib.hs" and "pass" it to the IRC message handler to then pass it into the plugins. Moving the database connection inside the plugins means that it no longer takes a database connection as an argument. The IRC message handler now has a lot of duplication, but it basically works, which is super exciting! Took a _long_ time to figure out the proper way to get the types to line up and get this compiling, but really glad it's working now! The magic function turned out to be `liftIO` to extract the `Either String String` out of its `IO` monad wrapper to be fed to the `IRC.send` function. Not a fan of the type conversion between `String` and `Data.Text`, so we'll eventually have to convert our plugins to use `Data.Text`.
2017-08-13Lib.hs: Move IRC-related code to a new "IRC" moduleTeddy Wing
Now that we have something sort of working on the IRC side of things, we can move it out into its own module to keep `Lib` clear and tidy.
2017-08-13dispatchEvent: Ignore user's hostname argumentTeddy Wing
We don't need this information. I was just saving it to find out what that argument actually was.
2017-08-13Lib.hs: Bot now responds on the channel that message came fromTeddy Wing
Instead of always responding on a hard-coded channel, the bot now responds on the channel the PRIVMSG was received on. This can be either a regular channel or a query message. The `serv` argument is apparently the message sender's hostname. Wanted to print it out to see what that argument was. I had been following this example from "barrucadu"'s 'yukibot': https://github.com/barrucadu/yukibot/blob/31930b234eb423ed74546b56ada100105c1680ce/yukibot-backend-irc/Yukibot/Backend/IRC.hs#L152-L156 but the code ignored the first `Event` argument. In order to send it as a chat message, needed to convert it to a `Data.Text`, using the method courtesy of this tutorial: https://haskell-lang.org/tutorial/string-types
2017-08-13Lib.hs: Test chat message listening and postingTeddy Wing
Add an event handler that gets called when a message is posted to a channel the bot is on. When a message is posted, the bot will send a chat message containing the text "test". This tests out the message handling and posting mechanism, and gives us a place to build off of to allow the bot to communicate.
2017-08-12Lib.hs: Make `Network.IRC.Client` a qualified importTeddy Wing
Make it a bit more obvious where these functions are coming from by prefixing them with `IRC.`.
2017-08-12stack.yaml: Turn off `-support_aesni` when compiling 'cryptonite'Teddy Wing
The 'irc-client' package depends on 'cryptonite'. I was getting this compilation error from 'cryptonite' on my machine: [111 of 111] Compiling Crypto.Cipher.AES ( Crypto/Cipher/AES.hs, .stack-work/dist/x86_64-osx/Cabal-1.24.2.0/build/Crypto/Cipher/AES.o ) cc1: error: unrecognized command line option "-maes" `gcc' failed in phase `C Compiler'. (Exit code: 1) The package recommends disabling AESNI via a compile flag to get around this error (https://github.com/haskell-crypto/cryptonite#known-building-issues): cabal configure --flag='-support_aesni' Add 'cryptonite' to our `extra-deps` in order to be able to set a flag on it. Turn off the `-support_aesni` flag in order to facilitate compilation.
2017-08-12Set up basic IRC supportTeddy Wing
Add the 'irc-client' package to facilitate communication over IRC. Copy the example from: http://hackage.haskell.org/package/irc-client-0.4.4.4/docs/Network-IRC-Client.html which connects to a network. We specify a channel to join, and what do you know, it works! Pretty cool. Commented out the code that runs the GitHub Commit plugin for now while testing this. Add the `OverloadedStrings` extension so we can write string literals but have them converted into the appropriate `Data.Text` and `Data.ByteString` types required by the IRC library.
2017-08-11gitHubCommitAction: Add missing period to error messageTeddy Wing
2017-08-11gitHubCommitAction: Fix whitespaceTeddy Wing
The `=` was previously aligned with the function definition below, but since the pattern match of the lower function definition changed, the `=`s were no longer aligned. Seems like it would be weird to move the `=` out and create a bunch of blank space to align the two `=`s, so moving the function body to the next line.
2017-08-11gitHubCommitAction: Ignore unused variableTeddy Wing
2017-08-11Lib.hs: Move `putStrLn` outside the `case` statementTeddy Wing
It's duplicated so I figured I'd take it out.
2017-08-10gitHubCommitAction: Get error handling to work using `Either`Teddy Wing
Get rid of the `fail` and use an `Either` for error handling instead. This allows us to send back the response string like before, but provide an additional error message when no data comes back from the database query. Remove the old error handling code I had tried to set up previously.
2017-08-10Try to set up error handling for GitHub Commit pluginTeddy Wing
This doesn't really work, but I wanted to hold onto this step. I've been reading about error handling, notably this article: http://www.randomhacks.net/2007/03/10/haskell-8-ways-to-report-errors/ I kind of like the idea of just using `fail`, and being able to have that set up some polymorphism to handle `Maybe`, `Either`, and `IO` situations, but today read some literature that discouraged using fail, since not all monads implement it. Anyway, this code doesn't print out the error string like I intended it to, so I guess I'll have to use `Either` instead.
2017-08-10Add TODOTeddy Wing
A few tasks to set up some clear next steps.
2017-08-03GitHubCommit.hs: Only select `repo_url` column from databaseTeddy Wing
We don't need to select the channel because we don't do anything with it. All we need is the repo URL. Create a new data type for use with the database query that allows us to select only the URL. Remove the `ChannelRepoUrl` type as it's no longer needed.
2017-08-03GitHubCommit.hs: Select row corresponding to correct channelTeddy Wing
Ask for the row corresponding to the channel received from the chat message. This gets rid of the previously hard-coded SQL and allows us to dynamically get the right URL value.
2017-08-02GitHubCommit.hs: Remove progress development commentsTeddy Wing
Added these while developing ff00355ade021d3e06d55017c5337f488474e5cb to test out different theories while trying to get the project to compile. These are no longer relevant any more, so delete them.
2017-08-02ChannelRepoUrl: Get rid of the `id` fieldTeddy Wing
We're not using it, and originally I didn't even put it in my SELECT query (which actually messed me up for a couple hours, as two columns in the SELECT does not match three columns in the data type). Added it later as a fix for that problem. But since I don't really want or need to select the id, we shouldn't bother, and in order to do so, we need to update the Haskell data type to only include two fields, so sqlite-simple can correctly convert the data.
2017-08-02Connect plugins to the databaseTeddy Wing
The GitHub Commit plugin needs access to the database in order to work properly. Include 'sqlite-simple' to give us access to the database and have it transform rows into Haskell objects. This change has the unfortunate effect of forcing us to make `PluginAction` an IO type. This means we'll need to make all our plugin action functions use IO, even the pure ones. `PluginAction` now takes a database connection as a second argument, and returns an `IO String`. I don't like the fact that the database argument is effectively hard-coded. Thus the TODO note to try to make a type class to replace it so we can pass a null database connection when it isn't needed. Eventually, if more things like this need to be passed into the function, we might consider making a new struct type for the purpose. In order to be able to use the `query_` function, which takes a String-like `Query`, we have to declare `OverloadedStrings`. Now in `gitHubCommitAction` we take the database connection as an argument, select a row (for now it's always the first one to test this out), and send back a GitHub commit URL (if a record matched, otherwise return an empty string). Eventually we'll want to make this more real by selecting the row corresponding to the channel in `message`. Also, instead of returning an empty string, we should be returning an `Either`, so the error state is clear. Update the `ChannelRepoUrl` data constructor to use record syntax so we can name its fields.
2017-08-02Plugin.hs(performPlugin): Use `PluginAction` typeTeddy Wing
Instead of manually writing out the type of the action function returned from `performPlugin`, use the consolidated `PluginAction` type. This makes it easier for us to change the `PluginAction` type signature if necessary.
2017-08-02GitHubCommit.hs: Make types of `ChannelRepoUrl` more specificTeddy Wing
Define some extra types in `ChannelRepoUrl` because I didn't like the generic ones.
2017-08-02GitHubCommit.hs: Add `ChannelRepoUrl` database typeTeddy Wing
A type that will be used in conjunction with 'sqlite-simple' to read values from the plugin's database table.
2017-08-02Change `PluginAction` type to `Message -> String`Teddy Wing
Have `PluginAction` functions take a Message type instead of a plain string. This gives us access to additional fields on the message: channel and nick. sorbot.cabal: Add `Message` to `exposed-modules` in order to be able to use it when building. Lib.hs: Change our test message to be a `Message` data type to conform to the new `PluginAction` interface. Plugin.hs: Use `Message` where appropriate. When calling `perform`, pass it a `Message` instead of a `String`. This means we have to match the regex within the plugin in order to get the match data. The benefit of that change is that now we have access to the full message in the plugin if we need it, not just the regex-filtered part. GitHubCommit.hs: Do a regex match against the Message text in order to get the SHA we want from the message.
2017-08-02Plugin/Base.hs: Remove duplicated exportsTeddy Wing
When I added the `Plugin(..)` export, I didn't think to remove the exports for the functions created by the Plugin record data type. Didn't see the warnings from the compiler when building until now.
2017-08-02Lib.hs: Remove unused `Text.Regex.TDFA` importTeddy Wing
We previously removed the call to `=~` that we needed this import for in 4bb65c50a2a85404af6d122acc53b6fb1739652b.
