由 时光怂恿深爱的人放手 提交于 2020-01-04 12:16:17
问题 I want to copy from the Ubuntu Linux clipboard into R Studio. My workflow consists of moving back and forth between R Studio and LibreOffice Calc. I've found the following code for writing to a Linux X11 clipboard, but I don't know how to read from it. Write to X11 Linux clipboard: clipboard <- function(x, sep="\t", row.names=FALSE, col.names=TRUE){ con <- pipe("xclip -selection clipboard -i", open="w") write.table(x, con, sep=sep, row.names=row.names, col.names=col.names) close(con) } #

问题 There plenty of examples on how to use Python to control the LibreOffice text document and spreadsheet but very little documentation on how to use the drawing program. I am trying to figure out how to draw a flowchart or at least some shapes in LibreOffice using Python. I am using Windows 10 and the Python 3.3 that came with LibreOffice 5. There is a very good example of how to use spreadsheet LibreOffice Python example In the example the following lines are common if you use the text

问题 Pre-read note: I'm using LibreOffice rather than Excel, but most functions should apply to both. I'm making a spreadsheet where I have a bunch of data, and for every property (such as # of employees or a name) I need a function that calculates how many rows contain each distinct value. I already have the distinct values extracted, and now I'm using the following function to calculate how many rows have each value: =COUNTIF(start:end;value) . (Note that the semicolon is LibreOffice's way of

word转pdf

很多人在工作经常会遇到word转pdf功能，word转pdf还是比较复杂，网上各种包，如python的各种转换包，其实是存在很多问题 的，尤其是对比较复杂的格式，真正的还的是调用组件来转换，这里介绍的是LibreOffice，以MAC环境为例，没有装LibreOffice的 可以通过brew install LibreOffice 安装，安装成功具体应用代码如下： 1 #!/usr/bin/env python 2 # -*- coding:utf-8 -*- 3 # Author:Eric.yue 4 5 from subprocess import Popen, PIPE 6 def convert(src, dst): 7 d = {'src': src, 'dst': dst} 8 9 command = '/Applications/LibreOffice.app/Contents/MacOS/soffice --headless --invisible --convert-to pdf %(src)s --outdir %(dst)s' % d 10 11 process = Popen(command, stdout=PIPE, stderr=PIPE, shell=True) # I am aware of consequences of using `shell

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 核心优势 异构服务：支持多种运行环境 用于媒体文件转换的库或者二进制往往和业务的运行环境不同，对计算资源的需求也有较大的差异。 函数计算支持多种运行环境，支持为独立的转换函数定制算力单位，根据请求量自动伸缩，让核心业务和支持业务做到较好的分离。 灵活触发：支持多种触发方式 函数计算既可以通过集成事件源服务（OSS、API 网关、日志服务和表格存储）产生事件来触发函数执行，也可以通过 HTTP 触发器使用 HTTP 请求触发函数执行，还支持 API/SDK 直接调用函数。 弹性伸缩: 轻松应对负载的波峰波谷 函数计算提供跨可用区的容灾能力，根据请求量自动进行毫秒级弹性扩容，快速调度计算资源，轻松应对业务洪峰。 预留实例功能彻底消除实例冷启动带来的延时毛刺，为在线应用迁移至函数计算扫清障碍! 工程效率：搭建速度快，运维代价小 使用函数计算，开发者无需管理服务器等基础设施，只需编写并上传代码，函数计算准备好计算资源，弹性可靠地运行任务，并提供完备的日志与监控报警服务，帮助服务快速上线且免除繁琐的运维操作。 最佳实践 快速开发一个分布式 Puppeteer 网页截图服务 示例搭建了一个具备弹性的 Puppeteer 网页截图服务，实现的功能为：客户端将想要截图的网页地址发送给函数，函数负责渲染网页内容，并截图返回。

word转换pdf的技术方案，供参考。【doc/docx/ppt/pptx/xls/xlsx均支持转换】 本方案是 Java结合shell命令完成 ，不同于以往的仅依赖java组件转换或打印pdf的方案，需要目标服务器安装office套件，可选方案有OpenOffice和LibreOffice[二者源是一家产品]，安装完office套件后，使用office提供的脚本完成转换。安装LibreOffice时，为避免复杂的依赖关系，建议采用yum方式安装： yum install libreoffice 脚本内容：soffice --headless --invisible --convert-to pdf 源office文档路径 --outdir 目录存储目录 需要将以上脚本编写成sh脚本的形式，其中源路径需要配置成参数，由Java程序调用sh脚本时传入，转换结束后，到指定的目录可取到同名的pdf文档，再进行与业务相关的逻辑处理。注： 临时目录需要定期清理 ，防止存储过多临时文档，导致磁盘占满。 Java调用代码： Java代码 try { String shpath = "/tmp/topdf.sh" ; //脚本路径，脚本中需要将源doc路径配置成变量，由下行程序调用时入参 String cmd = "param" ; //xshell脚本入参 Process ps =
